Anthony that graph you have described is important but in a discussion with 
Paul Graham, we decided that some of the more violent tornadoes tend to 
occur in a group with high SRH and high CAPE at the same time.  I know that 
it would potentially be a massive complex. I think this may have been the 
case in Oklahoma City May 3 outbreak from observation of the satpic 
animation for the day. What do others think?

Hi Jonty,

Your thoughts are exactly what I am thinking about that we simply do not 
know. We have only covered a small proportion of our countryside over a two 
year period really. And usually when you want to be out there, you can't!!! 
Now the argument is not about chasing but I do believe that video and 
photographic evidence is more effective to help identify and also help 
educate others in identifying wall clouds, funnels and tornadoes as we see 
them rather than apply the typical model we see in the US documentaries 
where you tend to see text book cases, and often the footage you see are 
repeated time and time again in documentaries giving the impression of more 
violent tornadoes than actually occurs.

One question before I proceed: have the US chasers and researchers talked 
about Australian conditions? I mean have they been able to compare US 
satellite picture based data with supercell outbreaks here and even suspect 
probable tornadic activity? I am just curious as there may be patterns 
where one probably can with a high degree of certainty suspect tornadic 
activity..

However, I do believe that since conditions come together more often, then 
the US do have more tornadoes and therefore a larger proportion of larger 
ones. However, it seems the regularity of the conditions tends to occur 
April to June. Our storm season, like others of course, seems to be able to 
start from August and spread all the way to April in most years. We do not 
have a prescribed season.

Further, there was an argument put forward about the continental land mass 
allowing for cold air to come southwards with larger temperature 
differences but these tend to be more important and more frequent earlier 
in the season. As Jonty suggests, the synoptic conditions is not far 
fetched from Australia considering out latitude. I think the late 
spring/early summer season tends to be more aligned with similar profiles 
to what we enjoy here. Again the lower level jet is the key factor in my 
opinion that we have lacked in storms we have chased.

I think the answer will not come thoroughly from storm chasing alone but by 
improvements in remote sensing from satellites. Determining the wind flow 
at the surface and teaming up with observers/storm chasers is a very 
important project that I would like to be part of. It may help verify what 
conditions have occurred when we get more explosive environments - 
particularly when tornadic supercells are observed and perhaps compare to 
the US. Unfortunately, we do not have the "needs" for such research to take 
place but you never know if the US researchers may want to team up with 
Australian researchers to help improve global models on finer grid scale.

Anyway, I think it is an exciting time ahead.

Port Kembla 9:40am EST

It is fairly pizzling down in the Gong this morning. It has been fairly heavy since around 7pm last night, but since waking up at 5:30 this morning and donning the wet weather gear to ride to work it has been constant rain, mostly with small drops, but in the last two hours the intensity has been increasing markedly with frequent heavy periods of larger drops which would have to be close to 40mm+ per hour. I would guess that from the wind direction though that the heaviest rainfall would be just behind the escarpment and possibly southern Sydney where if it is heavier than here will be experiencing some flooding problems soon enough.

If the drizzle and rain of the last two nights and this morning doesn't green up the grass of Micheal T, then nothing will.

Cheers from a wet, but still stratocu'd Wollongong

Hi all,

Has anyone else had problems with the NSW AWS site available to the public?
I can access the current page with all of the stations on it but when you go
to individual stations for the last 72 hours of records, it hasn't been
updated since 10am Monday. Just wondering if its my server (although it
hasn't done this before) or at the Bom's end?

Hi all,

Ironically enough, Michael T's grass might not have been greened at all.
The obs for 9AM this morning show that both Wollongong and Bellambi got
about 20mm overnight but that Wollongong AWS (at Albion Park which is
closer to Michael) only got 0.2mm!

This sort of thing was also experienced in the metro with the airport
scoring more that double (94mm) anywhere else around. The radar revealed
that this was due to 'elongated' bands of showers moving on to the coast
and dumping on a 'small' area for an extended period of time.

Hi all

I don't know if anyone else has noticed this, but I was just playing
around with the satellite image loops provided by

http://207.133.112.37/cgi-bin/main.pl?aust

when I realised you can change the image size and number of images to
loop. For example, with the current IR loop

http://207.133.112.37/cgi-bin/movie.pl?sat+jpg+12+682+602+aust+ir+auir20011210231.jpg

the number '12' after the 'jpg' represents the number of images in the
loop, eg change this to 6, 16, etc

the next two numbers '682' and '602' are the image size.  This always
puzzled me why the loop image is so small compared to the still.  To get
the original size, just change these numbers to 1364 and 1204
respectively. The first number is the y-dimension, and the second the x.

These details apply also to the other loops provided.

Hi Jimmy,

Given that (IMO), these are one of the two most major factors - you'd
require both to be present in large quantities to produce the "perfect"
conditions.  If they both contribute to tornado liklihood, then you'd
expect both ingredients if present in large quantities to contribute to
larger/more violent tornadoes.  Ultimately the trade-off 'effect' would
tend to produce smaller/weaker/shorter lived tornadoes - but this is not
always the case, which I guess throws more fire into the debate of
tornadoes and how they form..

Hi Lyle,

Shear in itself can actually create instability.  For example, strong
diffluent or divergent jets actually cause a lower pressure around
them.  This is because more air is leaving the jet then enterting that
certain area.  (An analogy of this is actually something I've observed
at Withcott on the Warrego Hwy :)  Towards Withcott from Toowoomba, the
speed limit drops from 100 to 60, all the cars converge on each other
and bunch up as faster cars come from behind and slow down - there's
always people waiting near Withcott to join the highway, it's harder for
them here because there's lots of cars enterting.  Just on the east side
if Withcott, the speed limit goes from 60 to 100, the cars first to hit
the 100 sign accelerate away from the cars behind them - leaving space
for cars to join the highway.  Motto of this, you'll save time in busy
traffic trying to merge onto the highway on the east side of Withcott
heading east :-)  But it's the same in jets - with more air leaving the
region then enterting it (by region I mean over a small area of space,
ie several km/tens of km), this causes a low pressure region and air
below it moves upward to replace it.

Diffluent jets have a similar effect - just think of lots of cars
leaving the highway due to lots of exits, and there's a lot more room
for other cars to join.  IE - more air is leaving the area then entering
it, creating low pressure.  So this helps in adding buoyancy to the
updraft.  In high shear situations, low CAPE could prevail - but the
effects of an upper level trough/low and diffluent/divergent shear in
the mid-upper levels can assist in "pulling" an updraft (it doesn't
really pull though).  I think high shear situations tend to be stronger
in winter as the jets are lower, so their impact is felt stronger in the
lower levels.  A strong cold front, or even the convergence zone on the
coast due to wind friction (less friction on water than land), helps act
as a forcing mechanism.

<snip fascinating discussion>

Might I add another factor which might be hiding the number of Australian
tornados [along with low population density, low public knowledge of
supercells, bad road networks, not to mention any dynamic atmospheric
differences] - might there be a difference in the percentage of aussie
supercells that produce highly visible, easily verifyable to a member of
the lay public, condensation funnels?  If for some reason [higher
condensation levels, less available moisture etc] a large number of aussie
vorticies were only visible as a short inverted cone at cloudbase, and a
debris swirl if they touched down.  Hardly your average wedge that people
are familiar with on TV - they might not recognise a twister that was right
in front of them for what it was.

Might be blowing out of my proverbial, but it was a thought.

Hi all,

I may bore people here :)  But I finally did manage to watch the
documentary that was pointed out before (I taped it).  It was
interesting watching it, while it was slightly corny/angled at the UK
couple's life (I half expected you to be on it Les Crossan :-)

Besides the fact I love storms/weather - the woman did touch on one of
the fundamental reasons I love chasing.  The hours on the road (I love
driving though), but being in the middle of nowhere, out in the country,
just driving or sitting beside the road doing nothing...you're always in
a new surrounding environment, and it's the perfect opportunity to
reflect back on things in your life, think about any problems, think
about any dreams or aspirations - even try and solve the world's
problems :-)  It's just truly bliss sitting beside the roadside,
smelling the farming hay nearby from a light, humid N'ly in the 30C
temperatures.  It just really is so relaxing, and it adds a marked
contrast to the somewhat high-paced action that (hopefully!) happens
after!  It really is like a type of adventure, you don't really know
what's going to happen, and you don't really know where you're going to
end up (although you have an idea).

I guess this is another aspect to why I love chasing for a couple of
weeks towards the end of year - again, ignoring the factor of 24/7 of
potential weather/storms!  But you never know where you're going to end
up, and it just makes it that little bit more exciting.  You learn a lot
about Australia travelling all over the country side, and you visit
places that you haven't even heard of before!  Each of them having some
aspect of them that sticks in your mind forever...to name just a few
(I'm sure many will know what I'm talking about):

- We got thrown out of a restaurant in Thargomindah for asking to buy
dinner, and a certain person got half the town drunk in the pub and then
there was a domestic at 12:30am in the motel carpark!
- The Warrego Wizzard in Charleville
- The "button person" in Bourke
- Cunnamulla pizza poisoning & powerade night
- In Theodore if 3 people tried to talk on their mobile, the signal
would all drop out
- "The Quirindi Wind Event" 

The list goes on and on, lots of memories, lots of fun!

I liked how this documentary commented and touched on a few of these
sorts of points (ie, it's not *just* the weather), it's just great full
stop!

Reflecting back on last year, it was the first year I was truly able to
chase properly, and while the season didn't even match past seasons I
recall in Brisbane...it was infinitely better!  One of my favourite
events was November 2-7, I was able to chase on Nov3-6, covering over
2000km in SE QLD.  It was absolutely tremendous, the amount I learnt
about supercells was incredible!  There were other memorable moments -
in October, driving through a weak tornado was certainly a hair-raising
experience!  Followed by a few days after by a midnight outing to what
looked like weak thunderstorms, gave severe weather to parts of the Gold
Coast.  A week later Oct 25/26 was another great couple of days, with
lightning going all through the night on the 26th with some of the most
amazing (and frequent displays).  After TD2K (which was beyond any words
or description, both regarding weather and non-weather related things),
there were a couple of days of storms in the Downs.  I was able to chase
one of these days and got some very nice wind and hail, as well as some
nice lightning on video.  Things quietened down through December after
that, although around Christmas we had a couple of days of storms to wet
our appetite, and again towards the 2nd week of January.  January 17 and
18 were again, beyond words - at least, until I saw Michael Bath's
footage of this day (with anything else I had seen in QLD looking rather
tame) - truly incredible couple of supercells.  Again ten days after
that, another few days of storms gave some "fun chases" - although it
ended with a bit of a low note when while driving through heavy rain, my
car careered into a floodway which I hadn't seen - the water was high
enough to nearly go over the bonnet.  Fortunately the damage to the car
didn't exceed much over $200.  February was rather quiet though storm
wise.  Although we did get some rather significant flooding!

March was great - although the quality of storms wasn't always there,
but March 9 let everyone know that the storm season wasn't over yet! 
Some some places receiving 200mm in 50mins.  A few days after, what was
a fairly benign (yet nice!) looking shelf cloud turned into a monster,
which made my day!  To complete it, a 2hr lightning show with lightning
over second spread across a 180 degree northern horizon.  It was by then
I was truly content - I had already "talked to myself" about the season
winding down, and it had done the opposite!  There were up to about 18
or so thunderdays in SEQ during March, certainly quite active!  Humidity
was very high for a large chunk of this.  Even April came as a bonus
when just recently we had some storms in SEQ and the Downs.  And even
now there are storms to the NW of Brisbane towards the Brisbane
Valley/NE Downs region.

It really has been a great year - it's not hard to say why I like
chasing so much, there are just so many aspects which make it enjoyable
for me!

Hi Phil,

There certainly is truth in what you say. Most of the tornadoes/possible 
tornadoes have been observed without the so-called typical text book funnel 
reaching the ground. Good point made but I suppose time will tell what is 
observed in the future.

The time when I stopped to think about what is observed here as compared to 
the US is when I saw chasers referring to wall clouds that didn't even look 
like such. I mean i nice circular base rotating either slightly or rapidly. 
Well, when I observe small prongs in videos, I found myself reflecting back 
on my photos only to find very similar examples.

An example might come in handy here:

http://australiasevereweather.com/photography/wall01.htm   refer to the 
wall cloud pics 3/4 way down the page with Riverstone and Rooty Hill listed 
on the same storm. If you doubt this, I have seen US examples and these 
were rotating (I think anti-cyclonically but I couldn't be sure) and the 
storm had a very strong updraught.

Also 
http://australiasevereweather.com/photography/photos/2000/1204jd12.jpg  now 
this one would not even qualify in most people's book but it rotated 
anti-cyclonically and was maintained for over 20 minutes but obviously was 
never going to do anything.

And this:

http://australiasevereweather.com/photography/photos/2000/1208jd04.jpg

Yes it was underneath the main updraught and eventually became this later on:

http://australiasevereweather.com/photography/photos/2000/1208jd14.jpg

Quite interesting.

Hi all,
      yeah a huge dumping over my place overnight(airport). I am still 
convinced that at least 30-40 mm of that fell in 15 minutes this morning 
around 7.30am. Driving to city around the airport tunnel traffic came to a 
grinding holt with cars pulling over,slamming on brakes and others stopping 
completely in the tunnel. Within minutes the road had become a torrent of 
moving water and i was becoming increasingly uncomfortable not moving in it! 
I swear that i couldnt see the car in front of me for a few minutes there, 
and no the windows wernt fogged up.It was like night time! Incredible stuff! 
Wonder if anyone can confirm this on radar?
      After all of this i was late for tech and it just so happens that 
everyone else in my class lives in the western suburbs, "what rain", "Your 
full of it" and "Heard that one before" were all thrown at me. Very annoyed, 
let me tell u!!
SEE YOU ALL LATER.
REGARDS JAMES P.

I agree with you Anthony, great post by the way, probably the first essay I 
have read of yours :)

Nothing like the thrill, the chase, the exploration of the country side, 
while less than 1km away the ground is being pelted with 1 inch hail stones 
and lightning that can only be counted in milli-seconds.

You hit the nail on the head Andrew. I spent a frustrating rainless night
here in Mt Warrigal. There was some drizzle when I left for work at 7.30am
this morning, which became heavier rain once in Wollongong itself.

There still is the potential for better things this week, but it depends on
that low in the Tasman, the various models are quite undecided about whether
it will head W/SW  or stay stationary then drift towards NZ. Either way I
expect the seas to pick up to quite large by Thursday.

what they look like - they are on reflective backing & measure approx 15
x 10cm & look absolutely stunning!!!  Great for cars, fridges,
schoolbags, luggage & anything else you want to make easily
recognisable!! They are $4 each (including postage & handling).

If you'd like to buy 1, 2, 4 (or 10 like someone whose name we won't
mention in Qld....) , just send a cheque or money order for the
appropriate amount made out to ASWA Inc, include your return postal
address & I'll pop them in the mail for you.

I think many of your points about chasing are similar to mine and others
too.

I must admit I like the excitement and anticipation of moving from air mass
and into another.

A classic example was the first group chase we had back in 1998 (
http://ozthunder.com/chase/tour.htm )
On the second week Jimmy, Paul Yole, myself and Clyve Herbert chased. The
day we left had seen a SE wind change move up the coast overnight. At
Wollongong it was overcast with the almost obligatory stratocumulus. However
once above the escarpment Paul and I could see far in the north a line of
castellanus. Therefore we knew the trough was roughly no more then 150kms
northwards. The excitement mounted.

We picked up Jimmy and Clyve and then hit the infamous Putty road. The start
of the road was under the stabilising SE, but as we ventured north we
eventually caught the trough line, then at around Singleton overtook it.

This is one of the aspects I love !!..........and it is one our USA brothers
( and sisters ) share too, how many times have you read a chase report
saying something like " we moved east to intercept the dryline " or " we
left Kansas under a grey overcast, but knew once we hit Texas we would again
be warm moist air "

The other aspect is learning. I think my 'gut knowledge' ( no wise cracks
please ) is very good, I do a lot on instinct and rarely refer to radar or
any data once on the road. However matched against this ability was a lack
of knowledge of things like what the upper atmosphere was doing, LI, and
CAPES, so chasing and interacting with other chasers has taught me many
skills over the years.

Don't worry MT, if weather knowledge and experience was measured by gut
size both you and I would be the world's leading storm chasers,
researches and forecasters! :-)

(caution - long email)</FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>Just a few comments regarding David's email 
below.&nbsp; </FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>Regarding Australia not having as good a severe 
storm set-up as other countries....well I don't know enough about other 
countries to comment on this so I'll leave this to those who know.</FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>As for the comment re: storms exhibiting strong low 
level rotation - I am a little inclined to agree to the portion of the statement 
which suggests we don't <U><STRONG>see</STRONG></U> a lot of this in Australia 
to a certain extent but I will discuss my reasons for this in the next 
statement.&nbsp; As for the comment that we don't <STRONG><U>get</U></STRONG> 
this strong rotation in the lower levels - I think this comes back to the point 
which relates to the lack of strong low level winds.&nbsp; One of the main 
features which we lack in Australia is the strong moisture laden low level winds 
which help provide that added shear.&nbsp; Yes, the coastal areas get their 
NE'lys which bring in the moist air but rarely are they travelling at speeds of 
any consequence.&nbsp; To make a comparison to the US, they often get surface 
(note the term surface)winds of 25-30knt (if not more)&nbsp;providing food for 
their&nbsp;hungry storms.&nbsp; This is generated by the strong low pressure 
systems which park themselves&nbsp;over W and NW states, providing 
the&nbsp;tight pressure gradient.&nbsp; In&nbsp;Australia (along the E coast to 
be more specific), NE'lys would normally be as a result of a trough sitting 
inland and usually this will not be deep enough to generate surface flow of more 
than 15knts.&nbsp; The few cases in Australia which has seen&nbsp;strong surface 
flow has resulted in tornadic supercells along the E seaboard (not necesarrily 
the coast).&nbsp; The three examples I refer to are 1st January 1970 
(Buladelah), 4th November 1973 (Brisbane) and 29th September 1996 (NSW).&nbsp; 
In all three events, a deep surface low was present, promoting the tight 
pressure gradient and generating the resultant strong low level winds.&nbsp; I 
may one day get around to doing a more in depth study of events such as these 
(as I'm sure there are many more examples of these synoptic set-ups) but time is 
a limiting factor at the moment.</FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>As for David's comment regarding the fact that the 
prime areas of severe storms has been well covered - I disagree with this 
statement.&nbsp; I don't beleive that the small number of chasers we have here 
in Australia and the large areas considered "prime" have been covered thoroughly 
at all.&nbsp; In just the past 12 months there has been many a time where a 
handful of the chasers have sat and watched massive cells (pure speculation 
based on radar and satellite observations) from their computers and 
commented..."geeze I wish I was under that cell" OR "wouldn't it be nice to be 
in Murwillumbah right now".&nbsp; Unfortunately, many (if not all) chasers are 
restricted to when and where they chase due to work, family and other 
committments.&nbsp; The only times when a majority of the storms on the E 
seaboard are watched closely is when the Thunder Down Under crew is out and 
about.&nbsp; It is this 3 week period when you can (almost) safely say the 
chasers are likely, on any given day, to be in the area which would be "prime" 
for that day's storms.&nbsp; Yes, there are still times when distance and other 
factors (such as floods) can restrict where we chase on these trips and becuase 
of this events will be missed.&nbsp; This was the case on the Thunder Down Under 
trip in late November 2000.&nbsp; On the 22nd of November, we chased between 
Emerald and Alpha (a few hundred km W of Rockhampton) and saw some awesome 
storms.&nbsp; On the 23rd we had a dilema as&nbsp;heavy rains earlier in the 
month had cut a few roads further W&nbsp;but the trough which had help kick off 
the storms from the previous day was expected to retreat inland.&nbsp; With a 
strong jet aloft and high dew points (into the mid 20's) so far inland we were 
very tempted to head out even further W and chase in the Longreach area with the 
chance of some severe storms for the next few days.&nbsp; On the other hand we 
had to consider the chance of being stranded in Longreach if more rain was to 
further increase water in the already flooded area and also the fact that we may 
put ourselves a long way out of the way for the next system which was forecast 
to come through in 4 more days in S NSW.&nbsp; Unfortunately, we decided not to 
risk being stranded and never headed out towards Longreach, yet on the 24th of 
November, the Bureau of Meteorology recieved a report of "large funnel shaped 
cloud on the ground" (ie tornado) just 35km SW of Longreach.&nbsp; Now i'm not 
saying that we would've seen this - this is not my point.&nbsp; My point is, is 
that chasers cannot be everywhere where it is primed for big storms.&nbsp; 
Another example of this can be seen by looking at the last 16 months in 
Victoria.&nbsp; There have been at least 8 confirmed tornadoes here of which 
only 1 was seen by a chaser, yet on all except one of the days when a tornado 
was reported, several chasers were out in the field.&nbsp;</FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>At the end of the last Victorian ASWA meeting, I 
had a brief chat with Harald Richter about the differences of chasing in 
Australia and the US and one thing which has stuck in my mind was the comment 
that in Australia, a lot of chasing is based on luck.&nbsp; I cannot emphasise 
enough how true I think this is.&nbsp; Given our limited weather data resources 
and access to real-time weather information whilst out in the field on top of 
the topography and road network in Australia, it is amazing how much luck comes 
into play.&nbsp; When you think that the avergae tornado lasts less than 10 
minutes, the probability of being in the right place and the right time and 
under the right storm is amazingly minute.&nbsp; Given the lack of understanding 
in how one storm becomes tornadic over another, it is amazing that chasers 
ANYWHERE (whether it be in the US, Germany, Australia or New Zealand or anywhere 
else) see tornadoes.&nbsp; How do they do this?&nbsp; They do this by reducing 
the luck factor.&nbsp; They look at what limited information they may have and 
they position themselves in the area which, given the current understanding of 
severe storms, is most likely to have the most severe storms on a particular 
day.&nbsp; They also position themselves near/under the biggest or most intense 
thunderstorm chaseable in that particular area.&nbsp; Not only this, they 
position themselves on the side of the storm which is most likely to produce a 
tornado.&nbsp; Immediately they are giving themselves a better chance at seeing 
a tornado than someone who is sitting on the wrong side of the dryline/trough 
line or someone sitting at home in their loungeroom.&nbsp; The more often they 
do this, the more the probablility increases that they will see a tornado.&nbsp; 
They have siginifcantly reduced the "luck" factor almost to the extent where IF 
the storm does produce a tornado, they will see it.&nbsp; It comes down to the 
individual storm.&nbsp; I guess what I am trying to say is that given the 
circumstances facing chasers in Australia, I think we are doing an excellent job 
in increasing our chances of seeing tornadoes (and other severe weather 
associated with thunderstorms). And in the process of doing this, also 
increasing the awareness of both the Bureau of Meteorology and the general 
public of the frequency of severe storms in Australia, ultimately in the hope 
that it will benefit these people (being the public) in the long term.&nbsp;

  <DIV>
  <DIV></DIV>&gt;&gt;The point about supercell research being mostly based on 
  the US </DIV>
  <DIV></DIV>&gt;&gt;experience 
  <DIV></DIV>&gt;&gt;is valid. I do personally believe we have a slightly 
  different 
  <DIV></DIV>
  <P>&gt;&gt;animal. </P>
  <DIV>
  <DIV>I agree Michael and I suppose this argument could be used anywhere in the 
  world. I think the US is quite unique in that it seems so ideally located and 
  geographically configured for&nbsp;'the' animal. To me Australia is not, and 
  I'm not sure thatwe have a&nbsp;severe storm 'set -up' any better than South 
  America or even Africa. I believe we have a less ideal setup&nbsp;than China, 
  and other parts of Asia (Bangladesh for example).</DIV>
  <DIV>&nbsp;</DIV>
  <DIV>Based on the efforts of chasers over the last several years, in my view 
  it is quite telling that no&nbsp;supercells with rapidly rotating wall clouds, 
  or even the dramatic base structure which is the hallmark of the US storms, 
  have been caught on video. We get giant hail,&nbsp;we get 100+ mph straight 
  line&nbsp;winds and monster 18+ km high storms.&nbsp;But we&nbsp;seem to get 
  very few storms that exhibit strong rotation at the lower levels, something 
  that I believe will be confirmed over the coming years. </DIV>
  <DIV>&nbsp;</DIV>
  <DIV>It is still early days as far as Australian chasing goes, but my 
  suspicion is that the prime areas have been well covered by chasers now. I 
  know great storms will continue to be caught on video although i think the 
  tornadoes will continue to be few and far between.&nbsp;In comparison to the 
  US, I think&nbsp;it is quite obvious that they get more&nbsp;supercells than 
  Australia and many more tornadic supercells. </DIV>
  <DIV>&nbsp;</DIV>
  <DIV>Based on my armchair observations over the last few years, a typical 
  spring period in the US sees instability persisting over much broader areas 
  than Australia, is more extreme and of course both speed and dierctional 
  windshear is much better. Still we get our fair share and as a storm chaser 
  rather than a tornado chaser, I for one am not dissapointed with what we get!

Hi all.
Some impressive vorticity north of Kalgoorlie tonight, looks like some good
rainfall in that area and embedded storms too.Also a very nice looking low
over the Tasman, interestingly this Tasman Sea low can in part be traced
back to a small wave low that developed along a weakening cold front a few
days ago over Victoria and then moved into the Tasman to be enhanced by some
pre existing vorticity in that area.
            regards Clyve Herbert.

Jimmy and all,

All valid points have been discussed here so far but I'd like to keep this
particular email restricted to just 1 comment made by Jimmy.

Note this email contains some humor as well as a serious aspect.

Quote "Unfortunately, we do not have the "needs" for such research to take
place"

 I think the "need" will come from an initial trigger.  Unfortunately this
trigger, as we have seen in the past, will have to be a significant event
and in this case it WILL be by a strong tornado (actually....a tornado that
takes several lives) passing through a populated area (most likely a captial
city).  There will then be 2 main driving forces behind the push for more
in-depth research and that will be the general public and the insurance
companies (and a 3rd if you include us storm chasers....hehe).  It will then
come down to the government (which I hope Anthony Cornelius is the Prime
Minister of Australia by then so he can just give us an open cheque book to
work with) and then we'll all be paid to chase 24/7 for 52 weeks a year (who
needs holidays if you can chase chase chase....).

But you can see what I'm getting at here in that the government will not see
the need for such funds to be given to the BoM until an unfortuante event
takes place.

Regards,

Macca

<DIV><FONT size=2>Last years TDU2K was great, but was the weather pattern

Phil, Jimmy and others,

I think you have raised an interesting point here Phil.  I have spoken to
people in the past of classifying eastern states thunderstorms into two
completely separate categories (yet as usual there are exceptions to these
and combinations of the two).

The first category being the "coastal storms" where the storms usually breed
on the ranges and then move off the ranges to affect coastal areas.  Due to
their proximity to the coast, these storms breed in mositure laden
environments with surface dewpoints consistently hitting 20C and above, yet
surface temperatures in these conditions rarely exceeds 33C.  This mositure
will often give these "coastal storms" the low based, HP appearance and in
the case of a funnel forming, you would expect the condensation level to be
at such a point where a significant portion of the funnel is visible (if not
engulfed in rain).

The second category is the "inland storms" where the storms breed W of the
ranges in air which is regularly significantly drier than that of the
coastal areas.  Dewpoints in the 12-18C range are far more likely and
surface temperatures are more likely to be in the 35-38C range, giving these
"inland storms" the higher base and in the case of a funnel forming the
higher condensation level would lead to the expectation that the
condensation funnel would be only partly visibile (if at all).  I know there
is the factor that high-based storms can have locally lowered LCL's but
given a general situation you would still expect the LCL to be lower in
these conditions than in the circumstances of the "coastal storms"
situation.

Its an interesting question to pose.  Perhaps another point to keep an eye
on in future chases/observations.

Hi Robert, and All.

    Well on closer examination of it there were three green ( will call it a
possible glitch(s) for now ), Yes we seen the one that was further to the left
relative to the other two and the ground. Which could indeed be streamers, but
it could also be interference from the charge build up before and during the
resulting Lightning Strike and it's separate pulses after the main strike. As
on any Digital Camera whether it be a Video Camera, SLR or a normal Compact
Digital Still Camera, they all take the Picture(s) via there CCD's ( Charged
Coupled Device ).
    So it's charge may have been interrupted or interfered with by the
proximity to the Lightning Discharge, and the Stepped Leader that came of the
Tree only  8 - 10 Metres to our right and slightly behind us. But in saying
that you would think that these Camera's more so with the real expensive ones
would have adequate Magnetic shielding ect... to help guard against such
Interference.

Hi Anthony,

I think i misundersttod your initial statment as you were clearly siting
that a large SRH can produce tornadic supercells with small CAPE, so long as
the CAPE is above a certain level. But i interpretted it as a 'proportional
argument' such that, at the extreme, very large SRH with zero CAPE could
produce a tornado - clearly not.

I like the car example! Do you know that Traffic Engineers actually use
fluid dynamic equations is their models - so it's a very accute observation
you made ;)

As a clarity note, when you talk about 'instability' and 'bouyancy' due to
diffluence aloft and convergence zones, i know you realise this is dynamic
modes rather than thermodynamic but for other people reading this message,
it should be noted that these are two different forcings producing a similar
effect.

Cheers, Lyle

G’day All,

There has basically been no weather in Tassie for 2
weeks. For just over a week, there has been light
winds and almost cloud free skies – well a least along
the NW Coast any way. It looks like the weather is on
annual leave down here. Oh well, it makes for pleasant
days I guess!

Hi Jonty and all,

Thanks for an excellent post Jonty.

Of course my presumptions might well be borne out of impatience! I know 
Australia can produce some very serious severe weather: strong tornadoes in 
1989 and strong / violent in 1992. [ I am particularly curious about 
November 1992 since F3 and F4 tornadoes where reported in Qld and a monster 
of unknown intensity photographed near Adelaide - perhaps these were even 
part of the same system? ]. Add to this Sept 1996 - a day when major 
tornadoes may have evaded watchful eyes, and clearly we get some very 
impressive stuff.

However I have yet to see any Australian system (since the inception of this 
list at least) which would 'seem' capable of having that much clout, though 
I realise a single tornadic supercell need not be restricted to such obvious 
potent large scale weather systems.  As a consequence though, I do often 
wonder how rare are these storm systems
and their progeny are in Australia?

I do think it is fair to say that the US is considerably 'stormier'
than Australia, both taken as a whole. A casual glance at the historical
lightning data of both countries would seem to indicate this. Following on 
from this, I think it is fairly reasonable to assume that, with
generally much more dynamic wind fields, that supercell numbers would,
therefore, be higher in the US. I tend to disagree with those who suggest 
that we get supercells in numbers comparable to the USA. Your are quite 
right in that my assumption on Australia seeing a lower proportion of 
tornadic supercells is nothing more than a guess - there is nothing to 
suggest that this is or indeed isn't the case. It really comes down to my 
own personal 'gut-feeling' and so has little in the way of any objective 
reality.

A few things led me to this gut feeling though. Outside of the tropics, 
central eastern Australia, appears to be the most storm active (again 
judging from the lightning maps and also more intensive observations over 
the last few years). This area I feel can 'cut it' with the eastern US in 
terms of severe storm frequency. My feeling is that if it doesn't happen 
often here (as the last few seasons would seem to indicate) then it wont be 
happening too often elsewhere (Booleroo is an example that it can and does 
happen - just not all that often). Since these areas have been well quite 
well chased in recent years, and given that the population density is not 
all that low in the broad area I am thinking of, I really am suprised that 
nothing significant  (tornado or
decent rotating wall cloud) has been bagged by this stage. Like the eastern 
US, particularly the southern areas, there would seem a relative abundance 
of HP supercells - correct me if I am wrong but I have thought that this 
'end of the spectrum' tends to develop in high CAPE and 'not ideal' shear 
conditions >> less tornadoes, particularly the stronger or longer lived 
variety. Again you and some others on the list are much better qualified 
than me to draw these conclusions, this is simply based on my own 
observations and the limited data available.

All in all it is fascinating subject and kind of frustrating in that it is 
limited to much speculation - what really goes on in our backyard. Of course 
it is hard to imagine the BoM getting government funding for any reasonable 
study, at least, as Macca stated, in the absence of a major tornado 
disaster. I suppose our best chance is if the US researchers took an 
interest in our supercells in a comparative sense. Our geography / 
topography / climate is very different and yet we do still produce these 
monster storms year in year out - how frequently with or without tornadoes 
is the question.

Hi David and all,

My feelings also are of that very nature: why hasn't a "major" tornado 
struck a populated area of Sydney. Now, I feel that looking into the Bureau 
database, you can find accounts of more major tornadic activity. But not 
only has it been quiet since in the past few years (Michael Bath and I have 
chased since 1993) but I feel based on storm patterns, it has been quiet 
for a lot longer with fewer tornadoes being reported in the past 20 years. 
Now although the Sydney area which really is a small area when you talk 
about tornadic occurrences, I believe that it does not represent the 
eastern side and nor do I think it represents the coastline. Well not at 
the moment. Other areas north of Sydney even along the coast tend to 
observe far more serious storms on a more regular occurrence and thence 
would have a higher probability of producing a tornado. Inland is a 
different kettle of fish. Even based on surface lifted index patterns to 
give an estimate of areas of instability, Sydney has not been able to match 
it with other parts of the state. I know the list jumps up and down when it 
does occur. (Please note in my arguments I don't consider for my own 
preference the waterspout tornadoes as the tornadoes from the supercell 
spectrum. I know in a study by Bart Geerts and someone else, they suggest 
that tornado frequencies approach some of the tornado alley states here in 
Sydney but he included the waterspouts which by definition are called 
tornados once on land)

David, I again cannot emphasise strongly enough that we have only touched 
the surface in chasing storms the last couple of years. Perhaps we have 
done more in this season than the previous and we shall continue to do so. 
Surely we have gone right around northern NSW and SE Qld, Victoria and also 
Adelaide region and SWA. But because of distances and work commitments as 
Andrew has suggested, we have not been able to chase on the days we really 
would have liked. And like I said, when someone chases and gets a tornado 
of significance, I can tell you that it would represent a significant find. 
In other words, getting an F3 here would be like chasing and getting an F5 
in the US and just as significant in my books. To me, a storm that produces 
an F3 is very significant as I have seen storms producing F5' in the US 
with a variety of damage paths varying usually from F3 to F5 along its most 
damaging paths.

Anyway, this is one healthy debate with some interesting points of view 
coming through. Another point I would like to add is that the US tends to 
have particular days when they can record 50 or so tornadoes or lets say 
well in the tens. Often these are the days most referred to on websites 
with the major tornadoes. So the most significant events tend to be 
highlighted in such a way that if one is not careful, it is almost presumed 
it was a different day. I know that is not the case with you David and 
others but I know when I first started looking through Storm Track, it 
certainly gave me that impression until I started to read the dates of the 
events. On a similar note, and one event comes to mind which was the 10th 
November 1997. I observed a wall cloud whilst on the same day, Paul Yole 
observed one and also suggested that somewhere towards the east of 
Victoria, a tornado was reported. That day was an outbreak and I believe 
the many storms that developed did develop in an ideal situation for severe 
storms that were sufficiently isolated that wall clouds would have been 
reported from quite a few storms. Now that was a storm system. I have 
provided for those of us who don't recall it some satpic examples. Looking 
back at it, it is also worth while for those in SA and WA to observe the 
satpics. They are listed at:

http://australiasevereweather.com/temp/9711/

Even if you are bored with my rambling on, please look.

http://australiasevereweather.com/storm_news/1997/docs/9711-01.htm  here is 
my link for the report on the day. You read the report and you would not 
think much of it....

I know it is wishful thinking, but I still maintain what we would see if 
someone got a bulldozer and opened up a 5km grid road network throughout 
the inland and we chased more regularly. I really feel it is a matter of 
time so be patient.

Anyway, I have things to do and keep rambling on... Keep this thread going.

<DIV><FONT size=2>Hi Simon and all</FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT size=2>I would imagine that this policy outlook is being formed based 
on the EC model. This model certainly does call for a major upper 
amplification(ie a sharp upper trough amplifying over eastern Australia over the 
weekend). It has sub-550 thicknesses pushing into southern QLD by late Sunday 
with a 548 thickness cold pool north of Brisbane on Monday. In response to this 
sharp upper level feature, it develops a surface low south of New Caledonia and 
drifts it westward and deepens rapidly into Tuesday/Wednesday. </FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT size=2>None of the other models I have seen are going for this, 
although NGP does suggest a northwestward propagation of an offshoot of the low 
currently in the south Tasman Sea. I personally cannot see the EC situation 
coming off, and looks very similar to what this particular model was doing in 
the winter of 1999 with upper level troughs constantly amplifying strongly in 
the east and ECLs forming willy-nilly. </FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT size=2>All models would suggest some intensification of showers into 
early next week with the passage of the upper trough, but whether it is to the 
extent EC is going for I am not too convinced. Either way, it should be 
interesting to watch over the next few days of relatively "boring" 
weather.</FONT></DIV>

Hi Simon,

I was always under the impression that a low causes a blocking high by
blocking the high, which blocks everything else...so a blocking low is
needed before a blocking high would be established...

Anthony

So, I guess the low starts the blocking.

Not sure if the current low is an classical example though.

Still I think there is an interestring weather pattern (in a synoptic sense)
developing over the next few days (as per Weather Co. reply).

Thanks
Simon

Hi David,

One of the points you raised was one of the angles I was coming at in
regards to the type of supercells we get here in Australia.  They tend
to be orientated more towards HP (typical of high CAPE, low shear
situations).  In the US, a warm dry layer exists at around 850mb, and
that rarely happens here - normally it's moist, and not much warmer. 
Sometimes it does exist, but rarely when there is an upper level trough
above it.  Rather, we get what I call high CAPe days (cap and CAPE),
often combining with a strong upper level ridge, that crushes the hope
of the mightiest of the Cu Hu (or even at times CJ's) of ever getting
started in such an environment.

I agree that HP cells tend to produce less tornadoes than classics, I
think a study has been conducted on this before in the US?  One of the
main reasons being that the precipitation and outflow of the storm tends
to frequently get caught up in the mesocyclone, suffocating it.  HP
supercells also though make it much harder for people to see tornadoes,
as they seem to frequently be rain wrapped!  The other thing I find
interesting is the term "cyclical supercell" - which I have often
wondered exactly what it means.  But I've assumed it to be a supercell
that continually cycles through stronger and weaker mesocyclonic phases,
during each phase producing another tornado.  If this was the case, you
would also expect that HP supercells would be less likely to exhibit
this type of pattern.

The other thing, is I believe what a lot of people in Australia often
scoff at (the "cold air tornado"), actually occurs in the US a fair bit
during winter/early spring - and are classified as "proper"
supercellular tornadoes.  Many people don't chase on these days as the
storms move too fast (I think in March a tornado was moving at 90-100mph
in the US!?)  A lot of "cold air tornadoes" would move very swiftly too.

To briefly swap over and reply to Jimmy's email - I agree that the
weather over the past 20 or so years has certainly appeared to be more
tame than say in the 1920's and 30's!  It's difficult to tell though,
but I would argue that the storm reports in the 20's and 30's are more
detailed, and more actually exist than in the 90's and 00's!  (For QLD
anyway).  I remember typing up some severe t'storm records, and the
reports were phenomenal...cars bonnets being peirced by hail, hail
drifts that froze cattle to death in summer (some up to 6ft deep!) 
There are other reports of houses and farms being completely
destroyed...one referred to one half of the street being undamaged, and
the other half a street difficult to tell farmhouses had existed there! 
Certainly some interesting stuff.  Australia's most expensive tornado
was the Brisbane Nov '73 tornado...and it brings up another issue.  In
the US, tornadoes are rated by the highest single damage they do to a
house.  In Australia, they tend to be averaged out.  The '73 tornado was
rated an F2 - but I think it's commonly believed an F3 rating is more
appropriate (and I have heard rumours that the BoM would reclassify this
as an F3?)  Yet interestingly, F4 damage was also reported from this
tornado!  

I think that again it comes down to population density...rarely does a
major tornado ever hit a major city in the US, and given that there are
even less major cities in Australia - the probability would be even
less.  In the 30's (I think...) there is a report of a tornado that went
through south Brisbane for 30 minutes, and it "destroyed houses," so
this is also interesting.

It really is a great subject!  I've been enjoying this thread immensely,
impatiently waiting for some one else to write about it :-)  As DC has
said - it's subject to a lot of speculation due to the large data gaps
that are present when you compare the two areas.

Hi David

I could not help but reply to this comment in your email
" I really am suprised that nothing significant  (tornado or decent rotating
wall cloud) has been bagged by this stage."
I have to disagree.... and below is a list of examples which i think prove this
:

Banana wall cloud (Banana was the closest township that would have been
demolished had a tornado formed, and is in QLD) bagged by TDU chasers last year,
of which all who attended would have photos.
http://www.sydneystormchasers.com/pictures/Matt/2000/tdu-11-21-00-09.htm

This wall cloud and funnel reached over 1/2 way to the ground, no time to stop
and see what was really happening, and also tree's were a big problem and we
could not see the ground underneath, also on TDU last year.
http://www.sydneystormchasers.com/pictures/Matt/2000/tdu-11-20-00-05.htm

This speaks for itself Nov3 last year.
http://www.sydneystormchasers.com/pictures/Matt/2000/11-03-00-11.htm

That is just from flicking through my website, im sure ASW/MSC/BSCH have plenty
of similar photogrophs from recent times, and looking on these sites, there are
countless photos of massive distant storms that were unchasable because of
roads/terrain, or because people were not able to chase, only take a photo from
their home or whatever, and you just know something is going on in and under
these storms... eg :
http://www.australiasevereweather.com/photography/photos/1996/0205mb02.jpg
http://www.australiasevereweather.com/photography/photos/1993/1226jd07.jpg
http://www.australiasevereweather.com/photography/photos/2000/1207jd04.jpg
http://www.australiasevereweather.com/photography/photos/2000/1104jd33.jpg
http://www.australiasevereweather.com/photography/photos/2000/1104jd25.jpg
that is just from a quick flick through ASW.

And the wall cloud on the front of Storm News issue 4 is one of the best I have
seen for Australia, always drool at it when i look !

I also do not think we get as much as america, but its not a competition. Based
on what HAS been reported in NSW/QLD (with regards to significant damage) alone
in Bureau databases and what not, and  considering the area and population size
of each state, I think that we do get our fair share of superell thunderstorms.
And I bet a lot is not reported because 99% of people go inside once a storm
hits and dont see a thing. Take that fact with the low population out of the
citys, well I dont need to say anymore cause people have heard this all before
:)
The next couple of years will be very interesting, and after time it will pay
off for the people that are out in the field making the effort... it comes down
to the old saying "you wont see anything sitting at home".

Hi,

Just a quick note on the point 'Sydney should ahve been hit by now', a
recent speaker here showed a diagram of the return interval for torndaos in
the US - the shortest interval for any one spot was 2000 years - that's no
typo. I'm not sure what grid size they were analysing on but it must have
been small. Either way, it gives an indication on how infrequent it is for a
tornado to strike the sample place twice in any human scale length of time.

I think to presume Australia gets any where near the number of events as the
US would be foolish, regardless of any point of 'population density' or
'doppler radar' arguments. We simply don't have the georgraphic setup to
produce those frequent high CAPE days, which, as Anothony was noting in
another post, can make up for a lack of any dynamic effects. Hence, I agree
with Jimmy's quote that an "F3 (oz) is as significant as an F5 (US)".

But if you are tornado starved, with so many landfalling cyclones in Aus
(relativly recently), i think that would be a prime spot to look for
tornado's but stick to radar chasing only :)

Cheers, Lyle

If you are wondering what Matt is referring to, the first three photos on 
this page illustrate:
http://australiasevereweather.com/photography/recd03.htm
This storm on 16/12/95 had gusts around 50 knots and hail to 5cm was 
reported in Lismore.

Also I have archived this important supercell discussion from 
aussie-weather which was kicked off by the Junee funnel observed by Robert 
Goler. I am learning so much from the discussion, it would be a waste for 
all this knowledge not be saved.

hello all,
Blair or Laurier in particular may be most likely to help me,any is 
contribution would be welcomed though.
has anyone got rainfall totals/data for the April 20-25 Victorian rainfall 
event?In particular i am chasing totals/data for the SE Strzelecki ranges 
(Balook,Mt.Tassie etc)although Otway figures would be of interest too.I know 
Balook had 395mm from 9am Saturday (21.4.2001) to 7pm Monday (23.4.2001)but 
it is to my knowledge that moderate-significant rain began falling on the 
night of Friday the 20th in the SE Strzelecki ranges and there was also some 
rain here/there on Tuesday the 24th.
any contributions please reply to anvil_industries at hotmail.com
thanks

I plan to do a more significant review of this event once the monthly
postal rainfall returns are in, as a few critical stations only report
by post. This will probably be another week or two.

Hi all

It appears as though a late season low has developed North Of the Northern
Territory (Arafura Sea) and moving West.

Anyone know what sort of development potential is given?

The cloud cluster associated with it is quite impressive.

Hi All,

Just to add another thought to this popular thread, and it is a subject I
have previously mentioned on this list in the past.

There is some debate as to whether the coriolis force plays a part in
inducing or maintaining rotation in a mesocyclone system.  If so (and it IS
very debateable), then in the Southern hemisphere you would expect the
coriolis force to act on rotation such as to weaken a northward moving
storm, and to strengthen a southward moving storm (for the same reason that
a cyclone cannnot cross the equator).

It is a singular fact that by far the vast majority of US tornado tracks run
in parallel from SW to NE, no matter what latitude throughout the entire US.
Therefore it can safely be assumed that the parent supercells are also
moving SW to NE.  Thus, while there are no doubt a great many supercell
thunderstorms in the US, it appears that only those on a SW to NE track
generally produce tornadoes, with only a very few exceptions.

Inverting this to the Southern Hemisphere, you would perhaps expect then a
similar situation would prevail, i.e., a requirement for tornadic supercells
to be on a NW to SE track.  While I have seen a great many supercell
thunderstorms in Australia, very few have been on this track, with most
storms being on a SW to NE track, i.e., perpendicular to the preferred
direction.  And some almost a S to N track (Sydney hailstorm for example,
and Gold Coast storms just last week - using the Coriolis theory, none of
these storms had much chance of producing a tornado).

But...  maybe the coriolis force has sweet FA to do with it, and it is all a
question of prevailing winds, shear, helicity aloft, CAPE, etc..  In which
case it just so happens that the circumstances which give rise to tornadic
supercells in the US also happens to be the same circumstances which move
those storms SW to NE.

And perhaps latitude does have something to do with it, with storm movement
tending to prefer a clockwise shift in directional vector as you move South
in the Southern hemisphere (along with frontal boundaries of winter time
lows).  With the majority of Australia lying further equatorward than most
of the US, that "might" explain the preferred storm direction.  (But lets
not get confused with frontal storms and associated 'coldies', lets stick to
Supercells).

Whatever, I have always treated a severe storm moving on a NW to SE track
with special caution...

I wonder if there has been any attempt made yet to gather all known tornado
tracks on a single map of Australia.  I wonder if the data is even
available, it sure would be an extremely interesting addition to the ASWA
web site.

John.

Good call Chris - as there are no Outlooks issued now (being out of season)
I have just emailed the BOM Darwin for a call re: this low. Will forward the
email, if relevant, to the list.

The Geostationary rain based satpics show an impressive 24hr accumulation
(over 180mm) so there is obviously some significant convection wrapped
inside this Low.

It is overcast here this morning with a storm located off the NW Coast
streaming its anvil south. With an onshore sea breeze kicking in at 1oam -
this seems to be the predominate wind - I really wonder where this system
will go (if it survives).

Rgds, Paul.

Hi all

It appears as though a late season low has developed North Of the Northern
Territory (Arafura Sea) and moving West.

Anyone know what sort of development potential is given?

The cloud cluster associated with it is quite impressive.

hello all,
Blair or Laurier in particular may be most likely to help me,any is

has anyone got rainfall totals/data for the April 20-25 Victorian rainfall
event?In particular i am chasing totals/data for the SE Strzelecki ranges
(Balook,Mt.Tassie etc)although Otway figures would be of interest too.I know
Balook had 395mm from 9am Saturday (21.4.2001) to 7pm Monday (23.4.2001)but
it is to my knowledge that moderate-significant rain began falling on the
night of Friday the 20th in the SE Strzelecki ranges and there was also some
rain here/there on Tuesday the 24th.
any contributions please reply to anvil_industries at hotmail.com

Hi John,

Just briefly - I remember James telling me/suggesting this to me a few
years ago when we first met...anyway, it is perhaps interesting that the
Nov '73 tornado in Brisbane moved NW to SE...but this is just one event
(but the first <and only> one that called to mind of significance.)

Also - coriolis wouldn't have much directly to do with vorticity through
potential vorticity...as it's normally considered a constant across a
given latitude.  But I believe there is an element of coriolis that
still exists, just the magnitude of question (ie, in theory coriolis
should apply to all of the atmosphere, but it would have a less
noticable effect on smaller distances, perhaps negligible, perhaps
not).  Interesting none the less :)

Hi John
I'm just going to reply to this part of your email :

I hope to do this once I have a significant amount of tornado data in the
tornadic events archive I have built on SSC. Once I feel there is enough to do
such a map, I will do one, which has been the aim all along of this archive, to
eventually plot the places where tornadoes have occured, and tracks if possible,
and see if there are any "hotspots" we do not know about.

The extremely limiting factor is the lack of Australian tornadic reports
publically available. The only place that would have this is obviously the
Bureau, and the odd media report Ben Quinn stumbles across from old channel 7
storm stories.
I will again ask if anyone has any information about tornadic events in
VIC/NSW/QLD to please email me, it would be most appreciated.

Anyway enough from me...

Matthew Smith

Hi list,
       It's been an excellent year for storms so far around here (despite 
being a bit dry in parts) and to add to it I've just seen my first and 
hopefully NOT my last funnel cloud/landspout/tornado, YEY! It lasted about 
10 min from 11:45am on the 22nd of April about 8-10km north of Wagga. There 
are three photos which turned out fairly well considering the camera used 
and Michael Thompson has been kind enough to offer to put them on his site. 
They were taken from about 5km away (it's hard to say exactly how far).
I couldn't see if it touched down or not as it was behind a hill and there 
was no thunder at the time and very little rain. The cloud did however, soon 
after the funnel and wall cloud dissipated, turn into a thunderstorm over 
Wagga with heavy showers (anywhere between 15 minutes and 30 minutes later).

I remember seeing a documentary called 'Eye of the Storm'
where a chaser is filming impressive updrafts associated with a tornadic 
supercell and he says something like, 'This is what video is for', referring 
to the ability of a video camera to catch motion. It would be nice to have 
had one in this instance. Not that I'm complaining =]

Regards Shane

G'Day Simon,

The BoM are now going for showers/storms in Brisbane on Sunday (max 24),
and cloudy/showers/storms in Brisbane on Monday (max 21).  I think
certainly we will see some sort of amplification of an upper trough - it
depends on the magnitude to exactly what happens.  AVN suggests very
cold 500 temps (-18C  at  500mb) for Sunday arvo and night over us, and
300mb temps around -43C - very cold for us (although not unusual).  The
only thing unusual about this sort of event is that normally we get
those sorts of upper level temps during SW'lies when it's too dry, but
they can occassionally occur with SE'lies.  I think one of the main
questions is will it be storms or (thundery) rain?  Large masses of
cloud are still present over NSW/Vic/SA - and there looks to be a
further injection of cold air in these places further increasing cloud. 
So it may come to us in cloud...but we can only hope it's cloud free!

But rest assured...I have actually planned a lot of study for an
upcomming major exam + some assignments due in soon over this long
weekend...so it's bound to get even more interesting purely for that
reason!

Lindsay...
The only two days when the temp failed to reached 22 in Darwin was 14
July 1968 whe the top was 21.1 and the 13 July 1968  21.8.
Min temps all occurred in late July 1942 - maybe the bombing of Darwin
effected the weather.
The min was 10.4 on 29/7/1942, 10.6 on 28/7/1942 and 10.8 on 31/7/1942.
The only other < 11 was 10.8 on 20/7/1965

As well, last year a 23 was recorded during the massive snowfall event down
South, which caused very cool dry easterlies to prevail for several days.

All MIN Max temps have been recorded during the dry - btw!

This area looks quite good in this pm's sat pics. But I alas I can't see it
developing too much further.

The month of May is traditionally the worst of the year for TC's globally. I
can't see this disturbance will change that statistic at this stage.

The April rainfall map for Se Australia from the BOM
http://www.bom.gov.au/cgi-bin/climate/rainmaps.cgi?page=map&variable=totals&
period=month&area=seaus

shows are massive difference in rainfall from Sydney to around Batemans Bay.

The northern half of Sydney is within the 100-200mm shading, yet head south
to Batemans Bay and you are in 5-10mm area.

My experience for April was that I had only about 30mm here, obviously more
fell in the gauge at Wollongong AWS, which is nearer the escarpment and at
Wollongong itself which tends to be wetter then the Shellharbour area.

Hi John and all,



>Whatever, I have always treated a severe storm moving on a NW to SE track
>with special caution...

I tend to agree with you on this one. I feel that you should find that the 
average of the all the winds forcing a SE movement (or lets say ESE 
movement for a left mover) is easier to attract IDEAL lower level wind 
shear than systems forced to move NE. I can tell you this summer has had 
very little in that regards. I also think this is the reason that 17th 
January 2001 did not produce tornadoes as it was well chased. I hoped for 
tornadoes and I know it was possible but I did not really hang as much hope 
on it. Of course it is easier to say after the event. What I am trying to 
say, the excitement for me what have been far greater to see a NW jet and 
then NE winds feeding. I feel too many people are always looking for 
greatest wind shear possible. But you must be careful. In forecasting, well 
I try to model in my mind what is going to happen at the various levels in 
the atmosphere (yes based on the models satpics etc) Assuming the models 
have been reasonable, you also try and visualise what the storms will do - 
create a good flanking line, what would happen if it moves left etc. Mario 
can tell you what I mean. What I can say about this season is besides a 
couple of days, the lower level winds have not really fallen into line with 
what I would say putting a smile on my face. Of course one cannot really 
predict what happens but you give it a try.

Having said this, I find it remarkable that people with all their various 
techniques are out there and tend to end up in the same areas!!!! Fascinating.

Hi all,

In my opinion this is turning into the most interesting thread weve had on
this list for almost years!!!  Keep it up.

Now in response to Lyle's email.

Its an interesting point re: the return interval for tornadoes.  I know of
several US towns (and I don't mean city sized ones) that have been hit by a
tornado more than once.  Of more interest though is the town of Milawa in
North Eastern Victoria (Australia) which has a population of just 270
people.  This town has been directly hit by 3 (yes three) tornadoes in the
past 50 years, with the most recent one being on 9th September 2000.
Further to this, the 2nd tornado was reported as having a damage path of 1km
wide (i think it was in the early 70's) and significant damage was done to
the well known Brown Brothers winery which is located on the outskirts of
the town.

A second factor to consider is the historical data of towns in NE NSW, of
which nearly every single town in that area has had at least 1 tornado
reported (time frame and reliability of this report is a little sketchy).

As for the frequency of high CAPE days, I will leave that for someone else
to answer (anthony) unless it hasn't been answered.  Then I'll throw in my
two bob's worth on that bit too.

As for tornadoes in landfalling cyclones......well....I've always wanted to
do a TC chase!!!!  BRING IT ON I SAY!!!!!!!!!!!!

Regards,

Andrew McDonald

John and all,

This is a very interesting point.  I'm far from an expert on this coriolis
business and will steer clear from it for now.  I can just provide some
relevant examples of NW-SE moving severe (tornadic) storms (in Victoria).

The first, most recent event is that of 8th August 2000 where a supercell
tracked SE from Maryborough/Castlemain area and it eventually passed over
Melbourne CBD (in its weakening phase).  This storm produced 3 confirmed
tornadoes all with NW-SE tracks.  Interesting.....

The second event I have bugger all information on except I think it is one
of the longest tornado tracks in Australian history and I'm pretty sure it
tracked NW - SE as well.  It was in South Western Victoria and I think it is
termed the "Casterton" tornado.  My memory isn't serving me well this
evening but a figure of 76km is popping in to my mind regarding the track
and F3 rating also pops into mind.  I have a feeling the book Cockeyed Bobs
and Willie Willies has information on it and I also think Clyve or Lindsay
Smail may be able to provide some more accurate information on it.

I also have a little feeling that another tornado (which struck the
outskirts of Geelong in the early 90's???) may've also had a NE-SW track.
Again I think the Geelong locals may be able to fill in the large gaps I
have left in this.

This could be something to look in to.

Regards,

Andrew McDonald

Hi Macca et al,

Considering the Schofields/Riverstone area, it has had 2 tornadoes in the 
database - 1965 in Schofields and 1984 in Schofields/Riverstone that I 
experienced though never saw, and I think from what I have heard from 1965 
and observed in the 1984 damage, they were pretty significant tornadoes - 
say more like F2 (certainly not the pissy F0's - F1's). Now the possible 
path width is about 4km for these two suburbs.

Now this is interesting. This area finds it difficult to score direct hits 
from severe storms though these significant events. Occasionally, it 
surprises me. Riverstone though from experience is more prone to severe 
storms overall and that is no exaggeration. The Bureau had tried to argue 
against myself and also Don White that there were no scientific reasoning 
to support these observations. I was even told once that it was an optical 
illusion in my observations.Yerrr right.

I have posted Shane's funnel cloud pictures up on a page at
http://ozthunder.com/chase/shane.htm

I think you will all be surprised. They are well worth a look at.

Shane reads this group so you can probably share with the group any replies.

Nice photographs!

Looks like a light precip curtain infront of the funnel, and possibly a dry slot
on the right hand side wrapping around.

Great catch Shane!

Evening Andrew & all,

The Casterton storm of 1st July 1989 spawned a tornado that was rated F3
at one point along its path, with most damage being consistent with an
F2 rating. This main track measured approx 70km & ran NW - SE from just
west of Poolaijelo to near Paschendale (near Casterton which is NE of Mt
Gambier). There appeared to have been more than 1 tornado.

Forcing mechanisms of this storm were (per the BoM preliminary report):
i) the storm was initiated on the leading edge of the upper cold pool
under a marked diffluent pattern with split jet structure.
ii) low level forcing played a role in initiating convection.

A squall line developed with several larger embedded cells in the line.
The line of storms moved east at ~40kmh, whilst individual cells within
the line moved SE at ~60kmh.

The Warragul tornado of 6th April 1994 (Gippsland).  This tornado was
also embedded in a squall line & was rated as low F2. The main focus of
this path was from west to east & was ~ 4km.)

The Halls Gap storm of 27th January 1997 (in western Victoria) also
moved southeastwards, dropping cricket ball sized hail & a tornado which
briefly touched down into Lake Fyans.

Hi Everyone

Myself and Matt Pearce were just looking at the models... and they look
very interesting for this weekend. MRF/GASP/NGP are all going for some
sort up strong upper trough (gasp has a low) forming over eastern NSW on
sat/sun/monday.
This cold pool looks very cool (as Anthony has pointed out) and  if it
holds it will bring some weather for us all, either a rain event or if
we are lucky a storm or 2. Cloud cover may be the deciding factor. This
system looks good for ok for NSW and QLD at this stage... will be an
interesting one to watch.

I think the generally accepted source of vorticity is the tiliting from the
horizontal to vertical in strong systems, the mechansims of which are
debatable. There is also the notion of surface convergence to 'spin-up' but
this can only account for week circulations - there simply isn't enough
vertical vorticty on the surface to explain the magnitude of the winds that
develop - note that land spouts (can be combintation of both forcings), dust
devils etc are primarily forced by surface convergence - hence their
weekness.

Reveiewing some modelling studies, the effect of CF in simulations is not
that strong but definatly evident - it produces the 'bowing' in squall lines
and can give preference to the right mover but more dynamical forces seem to
be at play.

I guess an interesting analogy is the bath tub. Common misconceptions are
that toilets and bath tubs will circulate in opposite directions in the
different hemispheres but this is not true - sort of. the ciruclation is
*mostly* forced by the geometry but, given a very still bath tub and you
remove the plug without disturbing the water, it will rotate cyclonically.
Why - because it's an unstable equilibrium and the very weak coriollis force
that develops can cause the fluid to veer into the cyclonic direction. This
was done in Labs. However, if you put your finger in and spin up the water
anti-cyclonically, it will merily go that way. Whats my point? That the
intial conditions and boundaries are very important but, left to it's own
devices, the CF can push the balance. Is this why mesocyclones circulate
cyclonically? - hey i'm not going that far, but it's worth thinking about.

Cheers, LYle

Hi Michael,

like i said, the grid size analysed on was not specified, so they could have
been talking about a 1m^2 grid block (not likely). But a long return
interval does imply rare occurence.
Wichita, Kansas is quite a large city but it's not like they get hit every
year/decade. But their RI is definatly not 2000 years ;)

Cheers, Lyle

Hi,

Re Tracks:

I must say that over the last year i have learn't a little bit about the
fundamentals of severe storms but have very little working knowledge - i
hope to change that by the end fo this chasing season! But, from what i know
of devlopment in the states, the situations that will produce an outbreak (a
prime chase day) is a negativly tiling trough or just a good jet aloft. That
translates to a mean flow direction that runs SW-NE, hence so do storms and,
thus, their tracks. I imagine this must be similar to Aus.

I really haven't found much literature on Australian tornadic events and,
from here, i think it will be people like Anthony, Jimmy (etc) that will
bring the community upto scratch - I personally look forward to this time ;)

As a side note to Anthony, I was showing a collegue your photo's who was
very impressed. Curious, was that big arcus cloud done with a 17mm?

Cheers, Lyle

G'day Matt, Anthony and others.

This is a great thread and I have certainly learned alot from all the posts!

When I mean significant I am making a comparison between what I have seen 
here (my own eyes or others videos) to what I have seen in the US - of 
course this is not really a fair comparison for the number of reasons which 
i wont re-iterate. Rest assured I have read every single Australian chase 
report that is online and have enjoyed every single one - some amazing 
storms have been bagged. Please dont think I am scoffing at the Australian 
events. For me it is all about comparison - not competition. It is all part 
of the one global puzzle. .

But in my oppinion, the only piece of Australian video which comes close to 
the kind of wallcloud 'appearance' I am thinking of, is video by yourself 
and Con Bitis of the 3/11/00 Sydney supercell. MT's 03/97 Shelharbour pics 
would indicate something similarly impressive - where was your camcorder 
Michael :-(. Other than these, relatively few Australian wall clouds have 
caught my attention. Jimmy's Oberon and Woolgoolga ones + a few others from 
other states look very good although rotation is impossible to make out in 
every case. In the US the chaser motto is along the lines "stay on the 
southwest side and you'll be fine". In Australia, I believe storm chasing 
will almost always be more fruitful if you stay on the NE as opposed to 
northwest side of a storm - not for tornadoes but for photogenic shelf 
clouds, dark bases, lightning, and of course updrafts.

On the banana wall cloud, to be honest, and as I have told Jimmy, it did not 
impress me as a wallcloud. Of course I wasn't there - you guys are the best 
judge, but to me rotation was not discernible from video. I have seen many 
storms which exhibit 'bouts' of lazy rotation, but that is a far cry from a 
storm that means tornado business. If I have to do a double take, and squint 
and stare to make out rotation, then I suppose I just didn't find it all 
that impressive although in all cases it is interesting (here I am talking 
only about such storms I have seen with my own eyes - not judging your 
example as I know alot can be lost on video).

>there are

That is what I ask myself all the time. But what is different about these 
monsters to the ones each of us has been under at some time where nothing 
obvious has happened? (I mean nothing in terms of rapid rotation) - I just 
wonder why should there be anything going on under these ones?.

>I think that we do get our fair share of superell thunderstorms.

couldn't agree more.

>Take that fact with the low population out of the

>before

As an aside, when I was drivng around last year, from western Oklahoma all 
the way up to Nebraska and beyond, I came to the conclusion that the 
population density in these parts is not all that different to say, SE QLD, 
the northern rivers, northwest slopes (near the ranges) or the Hunter.

You are right. If this was 1993 - perhaps we would be considering the fact 
that Brisbane storm chasers, five months earlier had bagged some violent 
tornadoes near Bucca, and how our SA group got that monster on video (or 
would we have missed then all??). But would our perspective of what is 
'normal' be distorted then or is it being distorted now by a lack of 
tornadic storms. I know that big day will come - again my whole point is how 
often??.


cheers,  Dave

The tornado which demolished the house I was in at Geelong (Vic) in 1946, 
travelled in a SE direction as it was seen by the neighbours as 
approaching from the NW and did further damage SE of the house.  I was 
too young to have any recollection of it myself, just relying on my 
grandfather's oral reports.  I don't have any knowledge of track details 
except that it travelled at least 4 km and probably further.

Hi Lyle,

An interesting thing about the SW'ly jets in the US - I guess for one
the Rockies really help with the upper level troughs (again due to the
PV equation), but Australia also receives nice upper level troughs,
however - if they exhibit a strong NW'ly jetstream that is present too
far north, it taps into the tropical moisture.  As many are aware - the
stronger winds/jet overlying slower winds create vorticity which lifts
the air up from underneath it, cooling and (if the air is moist enough,
which it often is in the tropical areas), condenses it.  I guess think
of waving your hand over a page in a book very quickly and the page will
rise/flap over.

Just due to the nature of upper level troughs, NW jets tend to have the
areas of divergence/diffluence - and SW jets tend to have areas of
convergence/confluence (but not always, this is just an ideal model of
an upper level trough), the left entry region does give some lifting
also.  The delta region (right exit of the jet), is present in NW'ly
jets, and is often one of the most favourable areas.  However, it is one
of my least favourite jets!  Purely because for us it brings in too much
upper moisture, and often is associated with cloud.  Sometimes it
produces too much rain.  However - in these situations, inland Australia
has often taken off beforehand, so one would wonder what lies under some
of the cells that have formed before the rain previous to that.  I
prefer SW'ly or W'ly jets (even though it normally means most of the
cold air is to our S), purely because we don't get the cloud.  We just
have to rely on our DP's being a bit higher to help add some extra
instability.

In regards to the big arcus cloud shot - this is going to sound
terrible, and I hope I don't sound too stuck up here...but which big
arcus cloud shot?  As there have been two that I think most people have
said are nice, they are:

shot with 4, 28mm lens photos digitally joined together - taken from

; The coolest maximum in the dry season I can recall was back in&nbsp; late
June, early July '90, which coincided with the the end of an event, when
Canberra had about 2 weeks when the max was always below 10 degrees C.&nbsp;
From memory at the end of this event (which by the way lead to 1.5 metres of
snow in the Brindabellas), Darwin's maximum was about 25 or 26 degrees, with
a fortnight's worth of cool air, being pumped up over them.</P>

I'm curious as to what the freezing levels would be over Darwin during such
outbreaks of cold southerly air in winter. How high would a mountain have to
be in that area to get snow?. (knowing that cold winter airstreams usually
have lost their moisture by the time they reach the far north)

Of course, this is an AVERAGE return period - there will always be
exceptions that will be struck multiple times [and in this day and age will
attract media coverage because of the 'freak' event] as well as places that
NEVER seem to get struck [which will attract no attention at all - except
from frustrated storm chasers!]

Hi everybody,

I have yet to contribute anything to this thread as my knowledge just doesn't give me an opportunity. But I have to agree that the sharing of information and the level of healthy debate has made it a very interesting read and one that is hopefully going to give us a whole army of knowledgeable tornado/funnel spotters.

But to pick up on the point of Matt Smith in his email yesterday afternoon. The collection of data to form a nation-wide map of tornado tracks probably should be something for all of us to share the workload on, as I'm sure if we were all to dig we would find quite a bit more anecdotal evidence to point to tornado damage. So the point I'd like to raise would be, why wouldn't everybody who has the time and interest to help get together and divide the nation into much smaller areas where we would each research possible tornado activity over a set time into the past and likewise going forward. Maybe this would be something which each state branch of ASWA can coordinate and hopefully there would be a reasonable enough of a spread so that most people who don't work at bom or other, would be able to research the areas where or closely nearby to where they live. But this would be up for anyone to work out.

We should try to run it as an organised project and set a targeted completion date, how the data is to be presented, etc, etc. Matt, I'm not trying to give you a job, but I'd see you as an overall coordinator as long as this project didn't become bigger than Ben Hur, and being able to place the info on the ssc page as you had planned.

I would be very interested to hear of your feedback on this idea as I feel it would have some other benefits to all of us, which might include the gaining of true knowledge of local conditions which are more likely to produce tornadic events or other severe weather, eg the Illawarra escarpment, or Hunter Valley areas. I'm sure this information in itself will be of great use at some stage down the track. Anyway, I'm sure this is enough rambling from myself, but  I'd nominate myself now as researching the nsw south coast area, down to whatever point unless someone wanted a pice of the action.

Cheers
Andrew Godsman

The tornado which demolished the house I was in at Geelong (Vic) in 1946, 
travelled in a SE direction as it was seen by the neighbours as 
approaching from the NW and did further damage SE of the house.  I was 
too young to have any recollection of it myself, just relying on my 
grandfather's oral reports.  I don't have any knowledge of track details 
except that it travelled at least 4 km and probably further.

As an aside, Matt Smith has been compiling  a tornado archive of the
occurences in the  Eastern States for the past few years. Its an interesting
read. Its something that Matt is always working on and its a great place to
start when it comes researching Australian Tornadoes.

Hi all,

You are not rambling Andrew. I think it is a good point.

What I would like to see is a project under way:

- for storms/tornado from all areas libraries

- snow reports included

We had tried to start up a snow group last year but it never got underway.

I feel that people should form a yahoo group for this project and then 
things might happen. Iwill let someone else take charge as I tried 
unsuccessfully last year so perhaps somebody else will have better luck.

Hi Michael, Shane et al,

That is a wonderful pic of a funnel and it clearly shows cyclonic rotation 
ie it is going the right way so to speak. Well done. As Matt Smith says, it 
has a nice dry slot which helps in descerning the direction of rotation. 
Which direction was the storm moving and which way are you facing?

This also illustrates one of the frustrating things. So close and still a 
couple of trees and hills in the way.

Great shot.

Hi Shane,

Just remembered that was the same day Robert Goler got his funnels. I 
wonder if there was no thunderstorm associated with it regardless of the 
fact there was no lightning. There is precipitation evident. Do you have a 
photo of the whole cloud or one facing a different direction. I take it you 
were facing NW in those photos. How about S at the same time or similar 
time. Helps immensely in deciding where this was in association with the 
parent cloud.

Thanks.

Hi all,

I am currently working on a project that counts the number of lightning 
strikes within a 30km or so radius. I have Most of the parts needed, but 
one thing I cannot seem to find anywhere (DSE, Jaycar, Altronics) is a 5 
digit counter. The guy who developed the circuit calls for a CONRAD 19 56 
50-44 (whatever that is). Does anyone know where I will be able to get some 
sort of Counter with either 4 or 5 digits???

Thanks

Greetings once more fellow list goers :)

I think this is going to come down to a fairly common thread in this
discussion (and I think I have talked about it before), but Australia
and the US both tend to use different types of CAPE.  US forecasts tend
to be orientated towards surface based calculations.  Australian
forecasts tend to be orientated towards PBL (Planetary Boundary Layer
based calculations).  IE the commonly accepted Australian methods tend
to take into account the moisture in the lower 50-100mb of the
atmosphere to get a representative measure of heat and moisture.  As if
you have a dry layer just above the surface (for example during
seabreeze situations on a dry day), the moisture at the surface really
isn't representative of the *mixed* parcel that would ascend into the
atmosphere.  For example, if you had a 4L bucket of cold water at 10C,
and you added 1L of hot water at 60C, and took the temperature at the
top, you would get a much higher temperature then if you mixed the 5L of
water together and took the temperature at the top.

I tend to always take an average of the bottom 50-100mb moisture depth
when I look at skew-T's, otherwise I believe that if you plotted
strictly using surface observations, if there is drier air just aloft
you will get an over-estimated parcel ascent.  Given that CAPE is
essentially the area between the parcel ascent and ELR (environmental
lapse rate), then subsequently your CAPE is adversely effected.  One
example of US CAPE and AU CAPE that comes to mind was the flop in April
in the US when the SPC had a high risk out for some areas.  CAPE was
2000-3000 in quite a few areas, but I was surprised when I looked at the
soundings how shallow the moisture layer was!  It was barely 100m deep,
and was way too shallow.  The same sounding in Australia would have
given CAPE's perhaps around 1000 if that.  So this can make it difficult
in even comparing CAPE calculations between the two areas!  But if you
brought Australia and US in line with each other in regards to CAPE, I
honestly believe that you will find that Australia will come out in
front in regards to high CAPE.  With DP's often getting into the low
20's, sometimes mid 20's in the coastal severe storm areas, and even
inland getting DP's in the high teens and temps in the high 30's or low
40's, CAPE's can get quite high.  NE NSW and SE QLD tend to be a nice
high CAPE corridor.  While we don't get huge upper level troughs very
frequently, during Nov/Dec events we tend to get coldish upper temps
(-10/-12C  at  500mb - sometimes less) and DP's are in the low 20's and
temps in the low 30's - you get some very nice CAPE's (4000-5000 is not
uncommon).  You require a fairly deep moist layer, but that is fairly
common, especially if PBL airmass over the Coral Sea is transported over
the area - this can happen quite quickly if there has not been much
injection of southerly air over the Coral!  Assuming surface CAPE
calculations, Some areas can get CAPE's towards five figures along the
east coast (more so towards Capricornia regions), with their mid-high 20
DP's!

More importantly, I think that CAPE in Australia tends to be utilised
more so than in the US.  In the US, you need a front/trough/dryline
mechanism to break the cap because it's so strong.  We do have strong
cap days here (with favourable upper atmospheres for storms), and that
can be broken by the ranges.  The ranges along the east coast of
Australia certainly get their fair share of severe storms, and the
population density is even less in these regions, with limited (treed)
roads.  Often in the US, the highest CAPE values go to waste because the
cap is too strong, rather the more modest CAPE's tend to get the chance
to break the cap.  Then again, if the cap does break over the big CAPE
areas (and shear is somewhat supportive)...they have had some biggins!

There are other factors that we tend to experence that you don't hear
much about in the US.  For example the seabreeze front, which is
actually a relatively new phenomena that has been 'discovered' by the
BoM.  This is most noticable on days when you have a NW'ly at the
surface - the seabreeze intrudes and you get an area of convergence, as
well as extra moisture.  The seabreeze front can either kill or make
storms very severe.  I know that from my experience the seabreeze front
tends to not be conducive for TS development if TS have not already
occurred.  But if TS have developed, they can ride along this boundary
and be quite severe.  I know a few events that have developed from the
seabreeze front - Nov '73, Oct 13 '98, Dec 16 '98.  Another one I
believe is Dec 12 '00, Paul Yole and I got slammed in by a storm that
intensified rapidlly as we were very close to it.  Just 40-50mins prior
to this, we had made the observation of a strong easterly that had
arrived as we were driving through Aratula.  It was early in the
afternoon (3pm?) but the seabreeze can go through areas in Toowoomba as
early as 2-3pm!  (To digress a little, I've noticed that in summer the
seabreeze can get in as far as Goondiwindi, St George and Roma!  Not
until very late though, around 3-4am in the morning, I've only noticed
this because sometimes if I wake up in the night to relieve myself, I do
what any normal and sane person would do - go by the computer, reload
GMSD and some obs :-)  And these areas tend to get sudden DP increases
by up to 10C during this time in the morning!)

Back to the CAPE subject - I think the other thing that makes it hard is
because we don't have reliable CAPE forecasts.  The aviation model does
CAPE forecasts, but I have found them incredibly inaccurate, often only
giving small areas of frequently under-estimated CAPE.  I don't know if
it has something to do with their equations, or whether or not it's just
because its not calculating/evaluating the surface moisture properly. 
Note that LI's suffer from a similar fate of inaccuracy, but is
certainly less noticable than CAPE inaccuracies.  Probably because a
small inaccuracy in the surface moisture profile can lead to huge
inaccuracies in CAPE (over 500-1000!)  Hence why I tend to calculate my
own CAPE.

Just thinking about this, I also wonder if the way we forecast storms
tends to be different to the way US chasers forecast their storms.  For
example, US chasers tend to primarily only be after one thing -
tornadoes!  Where as Australian chasers have always been happy with an
impressive storm - and we just forecast where we think the best storms
will be.  I don't often sit down and think "Now if I want a tornado,
where should I go?"  But it's difficult to do that simply because we
don't have data at a fine enough scale to do that!  I tend to just be
happy knowing there's 2000 CAPE there for instance, I mean one of my
forecast/chasing thoughts is once it gets to a certain level it doesn't
really matter how much - just as long as its unstable!  However it can
have some big effects - obviously there's a big difference between 2000
and 3000, but not between 2500 and 2800.

Hi Phil - Do you have a particular date in 1946?  All of my searching fails
to find a tornado in that year in Geelong.  There was however a severe storm
with strong gale force easterly winds (around 90 kph) on 18-1-46 which
caused a great deal of damage to houses, trees, etc.  On the 25-2-46 there
was a severe "electrical storm" through the Lorne-Geelong region  which
caused damage and at least 3 casualties.  Other than that there was a very
severe wind event in 1948 which demolished houses and uprooted trees right
across the urban area, hospitalising 4 people. But it was never described as
a tornado.  The Geelong Advertiser at the time said it was "the strongest
wind since the Highton Tornado of 1926."  Regards, Lindsay Smail.

The tornado which demolished the house I was in at Geelong (Vic) in 1946,
travelled in a SE direction as it was seen by the neighbours as
approaching from the NW and did further damage SE of the house.  I was
too young to have any recollection of it myself, just relying on my
grandfather's oral reports.  I don't have any knowledge of track details
except that it travelled at least 4 km and probably further.

Thanks Bill,
This is an interesting site.  I just had a look for information on
Antarctica for my eldest daughter who needs climatic information on the
continent.  I have tried a few sources but as yet I am unable to find a
great deal about it.  If anyone else can assist that would be fantastic.  I
hate geography assignments!!!!!!!!

It was definitely the 1948 event.  I would very much like to find out the 
exact date if you can look it up, as my Grandpa only narrowed it down 
to "when Phil was a baby" and couldn't be more specific.  I lived at 9 
Bloomsbury Street Chilwell from September 1946 until December 1948.  The 
main part of the house was then a thick walled stone or concrete house 
with a slate roof having no eaves around it.  The front half of the house 
was a poured concrete slab with mosaic tiling on top which had then had a 
big timber verandah with a corrugated iron roof built over it.  This had 
then been built in with some sort of timber siding and divided into a 
hallway and two rooms.  I was in one of the front rooms asleep when the 
tornado hit.  The rest of the family were in the main part of the house.
Grandpa used to tell it something like this:  It became so dark by three 
in the afternoon that they had to light the lamps (not commonly done in 
the daytime by my penny-counting grandparents).
A couple of times they went outside to look at the very dark and fast-
moving clouds.
They were inside when they heard a noise "like a dozen goods trains 
rolling downhill out of control".  The noise became unbelievable as 
everything outside seemed to be getting blown away.  Someone yelled 
out "Pray for the baby!"  As the noise abated, someone thought to check 
up on me.  They opened to door and found the whole front of the house 
absolutely missing - not a trace of walls, roof, windows - every stick of 
furniture vanished - except for one single item standing untouched under 
the open sky on the mosaic floor.  My pram was still exactly where it had 
been, with the mosquito net still in place, and yours truly still 
sleeping peacefully inside.
The neighbours had seen an enormous black column of rotating cloud 
approaching and had dived down into their cellars to escape.  Grandpa 
said a lot of damage had been done.
My Grandpa always used to tell this story to explain why I have been a 
weather nut all my life.

To place things into context more once I have heard on TV shows " I have
lived in Oklahoma all my life and have never seen one before "

I suppose we tend to think that they are so common that everybody has had a
brush with one.

Evening all,

Some nice CJs to go with the F18 aerial display this afternoon that
stopped traffic - if our phones were ringing, no-one was there to hear
them....everyone from al of the businesses was out in the street
watching the acrobatics. The rate of climb towards the cirrus at 28,000'
(?) was just breathtaking!!!!! Acrobatic altitude seemed to be as low as
2,000' (can someone confirm this?)...anyway, a bit of cloudwatching
thrown in - some nice convection to the W & NW of Melbourne this
afternoon with occasional lightning.

....and has anyone noticed a very small low lurking to the south of
Kangaroo Island?  Bears watching for the next couple of days. It's very
troughy over Victoria atm, eyes to the skies........

Hi Anthony

I must say that NW jets are too often moisture gravy trains. I was thinking
that if we can get ocean temperatures off the NW lower than normal we may
jet drier NW jets - or will the jets themselves be a vcitim of the cooler
water. Why I am thinking this is because at present parts of the Indian are
cooler than normal, if this were to persist until Spring  and even move more
north ?

Your thread below would be a great topic for the AGM, some overheads , etc
on the characteristics of the jets you describe.

Michael

The seabreeze is one of my pet loves and hates, I think you are onto
something with saying that the seabeeze can
be both a storm inhibiter or a storm assistant.

My experience in Wollongong is that the seabreeze will act as dreadful
inversion, sometimes only 800-1000m thick, and the cumulus/storms in the
first line against the seabreeze are often the strongest. The classic
example I can think of is the 11th December 1996.
http://ozthunder.com/chase/chase1.html  or
http://australiansevereweather.simplenet.com/storm_news/1996/docs/9612-01.ht
m
this day was memorable as the BOM had warnings out on almost the entire
state ( or was it the whole state ). I travelled from Wagga to Wollongong
that day and the cumulus was suffering for most of that distance through
lack of moisture. Most of the very severe storms that day fired along the
seabreeze boundary. The sat pics on Australia Severe Weather show this.

I suppose with seabreezes it is easy to be critical of the sea breeze when
you ignore what the steering winds are doing. Weak to zero steering winds
will see bugger all storms on the maritime side of the seabreeze. Any storms
would propagate back west riding the seabreeze. However with good steering
winds pushing the storm into the pool so to speak the storm itself will
break the seabreeze inversion and use the moisture.

Hi Michael,

Now that I have your attention as I have tried several times before, please 
change any of the links to our site from:

http://www.australiansevereweather.simplenet.com/

to http://australiasevereweather.com/

So
http://australiansevereweather.simplenet.com/storm_news/1996/docs/9612-01.ht
m

becomes

http://australiasevereweather.com/storm_news/1996/docs/9612-01.htm 
and so on

And Michael, a multiple copy and paste command will certainly change things 
quickly. Thanks Michael.

Hi Jimmy

You can stop panicking, the older link I quoted was simply from my web
browser, not one my web pages.

I had run a find and replace through my pages some time ago.

But your right, I should update my favourites as well as I may be causing
people to bookmark your old site.

Michael

Hi all,

Has anyone seen some of the soundings?  Some extremely impressive
instability!  Brisbane has LI's of -9986, Moree -9984, Melbourne -9978,
Adelaide -9976, Perth -9984, Sydney -9978 - but from the quick look I've
had at the soundings, Darwin takes the cake at -9988 LI's :-)  Obviously
some sort of error in the way the LI's were calculated in the soundings
tonight!

Yeah, probably only 2000ft Doubt they would have gone lower (Greg....what do
ya think?)

Hope ya got pics of the F18's.......oh...and the occasional cloud <G>

Had what looked to be a nice cell earlier today around 2:30om towards
Warracknabeal, but mainly only turkey towers the rest of the time. Hopefully
something will kick off soon

Evening all,

Some nice CJs to go with the F18 aerial display this afternoon that
stopped traffic - if our phones were ringing, no-one was there to hear
them....everyone from al of the businesses was out in the street
watching the acrobatics. The rate of climb towards the cirrus at 28,000'
(?) was just breathtaking!!!!! Acrobatic altitude seemed to be as low as
2,000' (can someone confirm this?)...anyway, a bit of cloudwatching
thrown in - some nice convection to the W & NW of Melbourne this
afternoon with occasional lightning.

....and has anyone noticed a very small low lurking to the south of
Kangaroo Island?  Bears watching for the next couple of days. It's very
troughy over Victoria atm, eyes to the skies........

Jane & Paul

If the Hornets were doing an aerial display for some event they would have been
as low as 500ft, climb rate is about 43,000 ft per minute from sea level. Still
waiting to see some hornets flying around Perth (storms too lol) havent seen
anything for a while now.

Evening / morning all,

Look at what we got when we sent Macca to Qld last year (cold outbreak),
& PaulY to Brisbane this year (great electrical storms & RAIN!).....I
tried it tonight when I over-reacted (no.... you don't get rid of me
*that* easily!!) to sinus medication & had to twiddle my thumbs in
Emergency for 4 hours waiting for the effects to wear off......but no
such luck!!<sigh>

Anyway, the Victorian aviation forecast looks interesting...
ISOLATED THUNDERSTORMS FAR NE TILL 14Z. ISOLATED THUNDERSTORMS/
SCATTERED SHOWERS FAR SW SEA EXTENDING TO SW OF LINE NARACOORTE/
FLINDERS ISLAND BY 23Z.

The public forecast reads:
Tonight and Saturday: Scattered showers and isolated thunderstorms,
mainly on and south of the ranges during Saturday.

OK, so SDS has set in already for the Victorians ....but I wouldn't be
surprised to see an interesting day in places in Victoria on Saturday
(ie: today), maybe early to mid morning for Melbourne, especially after
today's forecast....& those CJs...and that low / trough - upper-middle
level (by the look of it) lurking to our west - it's not big but it's
there & may have an interesting effect on our Saturday.

As an aside to Anthony's earlier email......what's it like when you see
a CJ or a Cb (or hear hail on the car roof on an old video in Jan
1998)???? I want to do is to drive in that direction to get closer, to
learn, to experience, to photograph.......but I also love sitting in a
paddock somewhere or the side of the road with a cup of tea for hours,
just watching & learning about the atmospheric processes - you see great
sunsets, dust devils & clouds demonstrating the physics of the whole
system in a visible manner.

I could never stop doing any of that!!!!!!  It gives me such peace &
joy!

Enjoy!!!!

Jane

Hmm, where are you, for starters?

I'm not familiar with that particular module.  Is it an integrated

Radio Spares in Melbourne carry all sorts of parts.  They're not cheap, but
have a very extensive range.

Hi Anthony,

an intersting read once again :) Just a few points...

I can't talk about the NWS but when forecasting here, we certainly mix the
PBL. In fact, check out www.rap.ucar.edu/weather - goto upper air and the
charts have automated LFC etc and you can see this product does mix the
PBL - of course, it is not NWS.

> With DP's often getting into the low
> 20's, sometimes mid 20's in the coastal severe storm areas, and even
> inland getting DP's in the high teens and temps in the high 30's or low
> 40's, CAPE's can get quite high.  NE NSW and SE QLD tend to be a nice

This is intersting, i know the other day i said that I thought the US had a
greater frequency of high CAPE days and i'm still out on that one - some
climatological analysis would be nice here - maybe after exams :) But I have
always been adamant that Aus get's higher DP's near the coast than any US
site - do we get high DP's inland up north?

However, i guess the importance is formation regions rather than just a
comparison of who can produce higher CAPES that never get utalised *or* goes
off everywhere and the storms become vapor starved. Also, the comment about
requiring dynamics to break the CIN is true but by no means the only
forcing - it does get bloody hot on the plains and breaking the cap is not
uncommon.

I wouldn't agree here. Most chasers here are very satisifed with an LP - a
tornado is a bonus. But picking a target to maximise the chance is always
the name of the game - but i think that has a lot to do with the fact that
you do ahve a real chance of seeing one whereas in oz it is more the luck of
the draw. Again - back to the argument of # of tonadoes in oz vs US etc.

Cheers, Lyle

As you go further NW into the "Survivor Outback" :-) the network of obs
gets less and less dense.  But one station comes to mind, Julia Creek -
guestimate, 700-800km W of Townsville, 400km S of the GoC.  I remember
making a comment on its afternoon obs how dry it was because the DP was
only 24 :)  The DP's tended to be 26-28 there most afternoons, but of
course it has the upper level tropical ridge on it.

Did you know that Mt Isa (250km W of Julia Creek) averages one severe
storm a year?  This is interesting (yes I know Mt Isa is the largest
city in the world...but this is the actual town/city itself), given that
actual centre is quite small, it's a fairly high frequency for somewhere
very close (if not in) the tropics!  Apparently they can get on the edge
of some jetstreams, and storms can be quite severe.  Just an interesting
aside I thought :)  Given the relative size of Mt Isa (I'm not sure what
it'd be, <10,000 though), it'd be like a suburb in Brisbane/Sydney
averaging a severe TS once a year (and some suburbs do...).

I guess my opinion of this is somewhat flavoured by the weather-chase
list and listening to many of the Americans forecast, and reading their
reports.  Often they tend to tone down any report that didn't have a
tornado.

Hi all,

Thanks to all who responded, I have found a suitable counter which actually 
is a 6 digit display. Just means I will be able to count more strikes, 
if/when we get a storm.

Once again thanks

Andrew

Hi all

Keep this discussion coming! - its about as close as we sould in SA are
going to get to severe weather in the next week or so [or in the last month
or so for that matter], enough of this slack pressure field I say!

Since we're talking wall clouds, anybody care to evaluate this:

What are we looking at here?

Lyle, Anthony, et all,

Anthony just mentioned Julia Creek as an inland place with high DP's and I'm
surprised he didn't comment on our last Thunder Down Under chase.  We spent
nearly the whole first week chasing in W NSW and W QLD (as far W as Burke -
Cunnamulla - Charleville - Alpha) and from the moment we got out to Burke
the DP was above 20 for the entire time.  Yes, there had been a lot of rain
and flooding out that way which would push the DP up above normal.  One
morning we woke up the day after Charleville had had its highest daily
rainfall total (for any month?) of 99.3mm (i think) and from 6:30am until
8:30am, temp and DP went from 20/20 up to 24/24 before the DP stopped going
up.  By midday we had obs of 31.5/24 which is fairly impressive by anyone's
standards.  We saw a few supercells this day and a wall cloud and funnel (or
3 <g>).  A few days later saw us out W of Rockhampton near Emerald.  A quick
check of the obs at one point saw the temp sitting on 29C whilst the DP
peaked ever so briefly at 27.2C but averaged 25C.  Unfortunately this day
the road network killed us.  THe storm to our SW was textbook multicell and
although briefly trying to go the next step, it never made it.  We still say
a HUGE microburst and some of the best pileus you'd ever see.  I'm not
entirely sure why.  There was another much larger and more persistent storm
to our N but the roads just couldn't get us there.

Anyway - that's my vote for the western areas.  They do get high DP's but
how regularly....who knows but the trees.  I guess over the next 3-5 years
when doing chases out there we may start to see a pattern but we can only
wait for the weather to take us back out there.

Regards,

Andrew McDonald

Hey people

Things are looking interesting in Vic today with the combination of a 
weak front and a amplyflying upper level trough producing plenty of 
instability.

Anyway, I have deceide to chase in Northern Vic/ Southern NSW, heading 
for that clearance. 

Updates aperciated.

I suppose everyone in sydney knows about the storms... nothing severe
but nice none the less. Heavy rain and a nice amount of lightning, and a
friend of Rune's had small hail at Eastern Creek.
This was expected but mid level cloud had me worried for a while, but as
a line of showers moved off the ranges t and the storms off the coast
slowly developed closer, it all went up nicely.
Fingers crossed for some more as this upper trough and cold pool (-22  at 
500!) does its work.

BTW thanks to Michael Bath for sending me some info on waterspouts off
Coff's Harbour, if anyone else has any contributions please let me know
so I can add them to the database.. Ill get to emailing you Vics about
the 1940's tornado near Geelong at a later date :)

Hi all,

A lot of work on severe storm/tornado climatology for the US has been done
by Harald Brooks and a few others at NSSL. You can see the results nicely
presented on a web page at

www.nssl.noaa.gov/hazard

There is stacks of information here, but I guess the parts relevant to
this thread are the maps of occurrence of severe weather within 25 miles
of a point. For example, many points in central Oklahoma can expect 7 to 8
days per year with severe hail (> 2cm) within 25 miles (this is the
highest for the country). If you look at giant hail (>5 cm) the figure
drops to about 2 or 3. 

For severe convective wind gusts, you initially may be surprised to find
the main peak is not on the great plains (although there is a peak here
too), but rather through the southern great lakes, Ohio and Indiana. This
is due to MCS or derecho events that produce widespread damaging
convective wind gusts.

Well, cutting to the big stuff, i.e. significant tornadoes (>= F2), not
surprisingly the peak is in central Oklahoma, and the value is around
about 30-35 days per century. So I guess you could look at it that if you
lived in central Oklahoma all your life and never went away, you would
expect to have about 30 or so significant tornadoes pass within 25 miles
of you. If you look at only violent tornadoes (F4 or F5) this drops to
about 4 or 5. 

(The length of the data sets varies - for the tornado data it is for the
period 1921-1995)

Other interesting stuff on Harald's home page

www.nssl.noaa.gov/~brooks

Cheers,

Jonty.

<DIV>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>All this talk of funnels etc in Australia must've 
encouraged a small storm over the north-western suburbs of Melbourne this 
afternoon.&nbsp; With the stong upper level system getting its acto together 
today, I expected some interesting things to develop, especially after seeing 
some nice small Cb's yesterday up in the Bendigo area where I was working.&nbsp; 
Once the fog cleared this morning, the cumulus showed itself and within a little 
while there were a few showers around.&nbsp; I took a quick wander outside to 
see if any of it was worth videoing (noticing that to the W there was a shower 
in the pink on radar) and low and behold FUNNEL!!!!&nbsp; At least I think it 
was.&nbsp; It persisted for about 3 minutes after I first saw it and it had 
quite nice shape and looked to be decended about 2/3 of the way to the ground 
(although the hilll in the foreground could distort that making it only 1/2 
way).&nbsp; Unfortunately the contrast was quite poor and the captures show up 
virtually nothing so I had to adjust the contrast and colour balance.&nbsp; 
</FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>I was a little unsure as to what this funnel was 
associated with and I went back out for another check a few minutes later and a 
little anvil had popped up right above where i'd seen the funnel.&nbsp; The top 
was only about 25,000ft and no thunder was heard.</FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>A little later another Cb developed just to my 
SE.&nbsp; I watched this as a new updraft kicked up on its south western flank 
and move overhead.&nbsp; Unfortunately there wasn't quite enough in it to 
generate hail but a nice moderate shower dumped right on my place.&nbsp; 
</FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>These weak Cb's developed across much of southern 
and north central victoria throughout the afternoon and come nice TCu on sunset 
was a good way to end the day.&nbsp; </FONT></DIV>

Hmm, where are you?  I'm in Niddrie, and the sky promised a lot at one stage,
but it fizzled out into a tame passing of a couple of cells here, then cleared
up.

For the record, I'm 12k NW of the city.

I did notice on the radar that there were cells around the Sunbury area at
times.

Carolyns message to 5 hours to get to the list because it was sent from:

	carolyn64 at bigpond.com

an address from which she is not subscribed. Majordomo only knows people
by the subscription address, and send all messages from other addresses to
me for manual aproval so we don't get inundated with spam. 

When I woke up this morning at 7:30 AM (I slept in because it's Saturday)
I saw the bounced message and approved it. It took me a couple of seconds
longer becuase of the html attachement. 4k seemed a bit large for a 2 line
message so I wanted to check the code for any Java or ActiveX reference
that might cause problems.

Carolys second message was sent from:

	carolyn at netcentral.com.au

the address she used when she subscribed to the list, and it went through
automaticaly.

If you have multiple addresses it might be best to subscribe to the list
from each address.

Hi all,

I feel perhaps luck was on my side today. I knew it as looking good but 
basically had to go up the coast lower Hunter basically for some work. Well 
basically everything timed well and on the way back I followed and videoed 
a storm. My parents were there and Geoff was with me as well as he came 
along. There was a mini chase on and we intercepted hail and some in minor 
coverage and collected on the side of the road in small piles nothing 
fancy. But the hail was in abundance mostly with diamters of about 1cm to 
1.5cm but some hailstones were up to 2cm. Unfortunately for me, Geoff (and 
mother who secretly enjoyed the chase doesn't want to admit it) we were not 
able to chase the best part of the storm with some of that lovely greyish 
mean green tinge. I suspect this area had the most dominant hail. The rain 
rates in some cases was incredible and extremely difficult to near 
impossible to see so I followed tail lights and in one case I stopped. I 
really enjoyed this late season May burst of hail. It has been reported to 
the Bureau as severe but I would say marginal would best decribe what we 
saw but I am confident that some sections of the hail areas were severe 
even if briefly. Wind gusts were  in some sections were quite strong 
although difficult to tell if severe, though the rainfall rate was 
definitely in the severe category - lots of run off. Nice storm.

Later on as the storm proceeded east, thunder was more frequent and deep 
rumbling occurred as I was on the phone.

I was also amazed at the organisation in this storm. It had real structure 
like any hailstorm.

Ahh and the funny bit, gosh I am a bastard, I started laughing whilst going 
back into the hail when we saw a group of bicycle riders racing with hail 
starting to fall on them. You hear it on the video. I just laughed because 
I never thought of that happening.

Cheers.

Hi All,

Woken by thunder at 4:00am in May!!  Nice little line of storms moving
through south of Ipswich with lightning rates to 100/5 mins.  Not bad
considering the surface temp here is around 14.5C.... Some nice bows in the
radar echo as well as pink & some red spots.

John.

Hi again,

Now gone 5:00am and the top end of line has passed through Mt. Crosby,
dumping around 10mm and no hail, some nice rifle shot cracks of thunder.
Activity has really tailed off according to lightning tracker, but radar
still looks OK, mainly CC stuff now.  Small red Blob Chappel Hill area
haading for the CBD.  But what bad timing?  If this had been 14 hours
earlier when surface temps were around 28C...
Still this is the best nightime activity at this location since Jan 17/18.

John.

Hi all,

Mario had just called that for about 10 minutes or so, he noticed clear 
rotation at Arncliffe. I would not be surprised based on the movement of 
the intense echo on radar. It seemed to move to the left of the mean level 
wind flow. He has photos of it and hopefully the photos do justice. No 
video camera I'm afraid.

Cheers

Hi Rune

Heavy rain here the last 15 minutes or so, had one of the closest lightning
strikes for a while to our house, within 100m, the inside of the caravan lite
up white (a hard task in the daytime !!) and crackbang thunder 1/2 a second
later.
Should be some reasonable totals from this rain in the 9am rain bulletin.
Any words from our friends in the Illawarra? surely you did not miss out
during this event !

8.30am sunday 6th may. Just observed a small wall
cloud between arncliffe and ashfield with
anticlockwise rotation and scud organizing itself
around a definite central point.At one point the scud
was coming in from every direction and incredibly fast
and a very weak broken funnel formed.Could've been an
old waterspout as it was weakening as it moved NW away
from Botany Bay, but then again........ Also lots of
very loud thunder.... yeah bring it on!!!

Nice little storm passed here(Redcliffe) around 7 am this morning. Hope there 
are some more coming... :-)

Hi John,

Got woken up by Dr Pearce/Andy (thanks guys!) about the impending storm,
I heard distant rumbles of thunder to begin with - the rain came quite
early, well before the closest thunder/lightning came.  Only scored one
flang, but some periods of heavy rain and gusty (40-50km/h) winds. 
Lightning/thunder started off at every 10seconds or so, but tapered off
towards the end.

You're not wrong about some interesting bows beforehand though, I went
through my radar archives and there's a couple of great bows in the line
of storms!!!  Wouldn't even be surprised if there was severe winds in
some areas of the line before it weakened and hit Brisbane.

If you look at the WV image, you can see a line along the dry slot that
has some small convection!  Very interesting, and this will most
probably fire today before moving eastwards.  The line is on the NE of
the upper level swirl on the WV image, it probably runs through the
western Downs, and in towards the Northern Tablelands, and Mid North
Coast, and NW towards the Maranoa and other districts.  The other line
of storms (which I think started near Moree yesterday), has moved out to
sea, although some are still going in the Wide Bay & Burnett regions!

An excited AC

Tony,

I'm in Greensborough in the NE suburbs.  This funnel shaped thing was a long
way to the W....i'd estimate a good 30-40km.  It was pretty distant so I'm
not going to say it definitely was or wasn't a funnel (unless someone else
saw it).

Regards,

Macca

David, I expected the email to be returned, from bigpond.
I was connected to that isp at the time and was getting reports of hail
around Newcastle at the time, and I did ask Dave Carroll to send for me
because I knew I was not subscribed with bigpond.  I will not subscribe with
bigpond because I will receive double the list then because all email go to
the one area...they are all connected on my email account, but bigpond wont
send with netcentral addy.

Hey all,

Speaking of wallclouds, I think I've finally got this right...

http://www.chariot.net.au/~paisley2/Elizabeth42000r4.jpg

Spotted north of Elizabeth from the Mt Lofty ranges on 9/4 last year.  What
is going on here?  Is this a tail cloud coming in from the left [south]?
There was lots of scud action and numerous CGs, but I was too far away to
see any obvious rotation, and no Andrew, this was not the same lowering
that you videoed from close up - it was several kilometres futher north.

Comments?

Cheers

Phil

Hi all,

We didn't miss out here either. CJs were visible to the far south around 
Grafton as evening approached yesterday. Just as it got dark the first 
flash was observed. I was out to dinner at Ballina and had a lovely view to 
the S and SW over the Richmond River so was able to enjoy the system move 
in. Only occasional flashes, no CGs observed but each one lit up the whole 
sky. Quite cool and fresh winds preceding some moderate rain and a few 
close lightning strikes around 10pm. This system headed towards the NE.

This morning at McLeans Ridges I was awoken just after 4am as more active 
cells spread in. Quite a few close CGs (within 1km) hit between 415 and 
430am and we had some torrential rain in that time - approximately 20mm 
fell. It's surprising all this happened at the same time as in Brisbane - 
must have been a good storm line!

cheers, Michael

Woken at 5am by that wonderful sound thunder - it has been a long time 
for some SEQenders. Only received 7mm, and only CC present here at 
Ashgrove. Still hoping for this afternoon, just wish I was up north of 
Kingaroy at present.

Nice little storm passed here(Redcliffe) around 7 am this morning. Hope

Whilst wet weather occurs over the west and east of the country, SA remains 
very dry for this time of year.  I admit WA definately needs the rain it's 
getting at the moment however I'm getting a bit sick of NSW especially 
getting so much wet weather.  The most interesting thing here in Adelaide at 
the moment is watching leaves blow of trees and whishing winter would hurry 
up and arrive.  Finally though in the 11:00am notes this morning, (this 
really shows how desperate I am for some interesting weather) there is 
mention of a front entering the SW of the Bight and amplifying possibly 
bringing some showers to SA later on in the week or weekend.  Models seem to 
be picking up this frontal activity but at the moment it doesn't look all 
that strong.  There is also the possibility of a shower or two on Tues. 
night or Wed. but I won't hold my breath for that.  Woith rainfall meant to 
be up around over 60mm by the end of this month I hope we get some decent 
falls soon or a very dry winter could be on the cards.  At the moment I'm 
trying to ignore the BOM's climate outlook of likely below average falls.  
I'm getting damn sick of sunny days too!!!!!  Going crazy.  Re-ignites that 
debate of the worst place to live and Adelaide is living up to that 
reputation.

As usual the ocean about 10kms offshore seemed to be the hotspot in the
Illawarra.

We had thunder yesterday, nothing special, just those short rumbles that
tell me the storm is over the ocean.

We have had 1-2mm from passing light showers and even the sun was out
briefly about 1.30pm.

Michael

It has certainly been fairly benign in Wollongong today, with only a little
rain and definately no thunder heard from North Wollongong. Yesterday down
at Coolangatta, (nsw south coast) there was a bit of rumbling and some
decently good rain. But by the looks of all the roads and cycleway along
north beach we had a heap of rain during the afternoon yesterday.

Michael T, an interesting story that was retold to me last night was of a
tornado back in early 1972 which came up from the lake and tracked SE across
Oak Flats and up towards the reservior on the hill. Apparently it caused
some good structural damage and completely demolished a partially built
house. My parents tell me it was covered extensively in the local media so I
might try to do some digging. At this stage I'd say the damage track was
around 1km (urban area) but unknown longer once it got into the sticks. And
the main reason I say interesting about this tornado, the NW to SE tracking.

Cheers
Andrew Godsman

Hi Everyone,

Well what a storm it was in the CBD of Sydney yesterday afternoon. I was on
a bus heading across Glebe Island bridge at about 2:15pm when it started to
absolutely pelt down with rain. It became so heavy that water was flowing
like a river across the road and forming lakes everywhere. The bus ploughed
through a couple of particularly deep areas sending a huge spray of water up
its side. Cars were stopping on the side of the road as the visibility
dropped to almost nothing. The lightning wasnt that frequent but it was
rather close as you could clearly hear the thunder inside the bus amongst
all the noise of the traffic and the torrential rain.

Matthew Piper

Hi Andrew - seeing you mentioned this - I rang my mum - who lived in Oak
Flats (as did I) around that time. You are right - it was described as a
waterspout that came off Lake Illawarra and then hit stoney range (the
reservoir wasn't there then as it was built in the early '80's).

Will be interesting to hear about it.

Paul.

As well - it may have killed someone living in the farmhouse at the time?
There seems to be a local legend about the farmhouse that was there (before
all the new development) where a person was killed and the family had to
leave the premises?

Could have this been the cause?

Yes SL.
 I know and understand your situation and weather situation.
The east coast of the South Island is suffering dry conditions so far this
year. The last 3 days in Christchurch have produced drizzle from the moist
NE flow over us at the moment which have resulted in the 2nd heaviest wet
period so far this year, a total of 12.6mm
...and it has only been drizzly rain.

The only stormy weather around Australia/NZ seems to be around New south
Wales area judging posts on this list. There has been heavy rainfall totals
around northern NZ areas but nothing really exeptional of note. 

John Gaul
NZ Boring Weather Society
(used to be the NZ Thunderstorm Soc but as thunderstorms are becoming a
rareity these days, I thought I had better change the name of the society
to something more appropriate with the weather resulting from weather
patterns these days ...anyone wants to join???)

Hi All,

Just back from a late arvo / evening chase. Lovely photogenic cells 
developed and spread into my area (Lismore Casino), with a possible 
spilting supercell west of Casino. I'll write it all up later but the 
highlight was on the trip home.

Heading E from Lismore the sky was ablaze with constant lightning - it 
looked severe just from the glimpses in the lightning to I kept going east 
along the Bruxner Highway and met torrential rain at Alphadale, then 1km 
further east the first hail smashed into the car. It sounded about 2cm 
diameter. I crept a few ks further east to Wollongbar and it just went 
berserk ! Copious amount of hail 1 to 2 cm diameter and incredible torrents 
of rain with strong gusts of S winds. The road became like ice and there 
was some fog from it. It was the first time I've seem enough hail on the 
road to make it look like snow, with the few cars still heading E making 
black tracks. It very quickly melted as the heavy rain persisted, all the 
while intense lightning flashes struck nearby, but hard to get an idea of 
where due to the noise of the car.

I noticed one driver had skidded off the road into a ditch.

I've uploaded a loop I saved:
http://australiasevereweather.com/temp/200105060930.gif

Quite an impressive blob of red !

regards, Michael

Andrew

You raise an interesting subject here. Despite my often whining about the
Illawarra weather, I have debated many a time whether the Lake Illawarra
area is a tornado hotspot.

There was my funnel in 1997. The 1972 incident you described, which also
affected Minnamurra spit, keeping pretty much in a NW/SE track. Then around
the early - mid sixties another event which damaged homes in Oak Flats, this
was described as a tornado at the time.

Further to that in 1956-57 a home was unroofed in Warrawong during a storm.
Eye witness reports suggest it was a funnel cloud, but one containing sparks
and fire - interesting !  perhaps this was a power transformer.

My theory is that the lake plays a role, especially in late summer to Autumn
when the lake water temperature is up to 28C, I know as when I worked in the
power station we used to measure the lake temperature. Although small in
area, it is non the less larger then a typical storm updraft base. The key
ingredient is getting low based convection to occur over the coastal plain,
once that happens any updraft over the lake has added fuel.

The March 1997 incident was proceeded by a ominous wallcloud that was
centred over the lake.........and guess what it moved NW-SE.

Hey all,

For the past week, Narelle Bowmaker has been chasing in the US. I am in
direct
contact with her while she is over there (Yes, most of you would have
noticed
in IRC that I have taken a majorly sudden interest in US weather). Anyway,
here
is her report for her first few days over there......enjoy.

Thurs 3rd May 2001 - Brownfield Hailer
------------------

Hey people!  Well my first day out was an eventful one!!

After a fairly leisurely start to the morning (much needed after the mammoth
13hr flight/30hr bus trek from Brisbane to the heart of Oklahoma City),
chase buddy Mark Roscovich and I left Yukon at approx 11am, heading out
toward the Lubbock area.

By 1630, situated just east of Tahoka, we recieved news from Tim Vasquez
that cells were developing rapidly along the TX/NM border with an alleged
tornado on the ground NW of Lubbock. (this has since been refuted - spotter
provided video which bore NO tornado.

The action began to really pick up around 1845 - we'd been heading west
toward Brownfield, and Mark had taken a north turn seeking an unobstructed
view of the cell moving towards us, but then I noticed what I appeared to be
a distinct funnel that quickly shot down and just as quickly retracted from
a highly active base/undefined wall cloud, back along our original path ...
Mark was reluctnant to retrace our steps and continue west, suspecting this
was one of countless scud bombs that abounded. Luckily we did though, and
positioned ourselves to the south west of Brownfield because we now found
ourselves to be literally on the side of a large slowly rotating base. A
hail shaft wrapped around us and showered us with 3/4 inch hail between
1855-1905 that came down in torrents. After a second wave of this we then
gassed up in Brownfield. As we left the station, DOW whizzed by on a
westerly track.. now we KNEW we had to be in the right place!

Proceeded NE out of Brownfield and caught up with slow moving storm that was
frequently pulsing.  Reports of 'baseballs' in this, found us tailing with
caution, Mark none too crazy to see his new truck christened with too many
dents... at one point, Mark was on the phone with Dave Ewoldt, when we heard
an almost deafening 'THUNK!' on the front of the car - followed by a
thorough pummelling by 1 to 2" inch hail. At this stage I think I heard Mark
muttering something along the lines of "..another fine mess I've gotten
ourselves into" - but while he prayed to heaven for the hail to slow down, I
was IN seventh heaven! ... well, the hail did slow down some, but even then,
with the window rolled down you could hear a VERY AUDIBLE hail roar! .. the
crescendo was majic!

We continued north bound slowly trying to stay just behind the hail core,
Mark's nerves weathering the odd deafening thuds on the roof .. we even
stopped to souvenier a singularly enormous stone from the centre of the
road, and admired and photographed our prize with childlike glee!! ...
without a rule or measure, it was still easily two and three quarters inch
in diameter .. gorgeous and perfect ... (and noted it was after midnight
before it even nearly melted away)

We continued to negotiate around the south side of the storm and arrived in
Lubbock around 2130. On the way in we were privvy to many strong CG's and a
particularly impressive multi-pulsing CG of several seconds duration.

Mark has yet to psyche himself up to checking out his new truck. I'm sure
there are a few new 'decorations' to say the least.

Overall, not a bad christening to the start of my 2001 USA Season!!!


Thurs 4th May - right place, wrong time
-------------

As for today, not enough cap, Storms will likely line out after 20Z.
We'll likely head out west and play what dryline there is. Not very
optimistic about today unless one wants to see more tropical like downpours
and gunge.

.... well, that's what I thought at about 3am this morning! And proved
partially true for W TX.

We took our time hanging out in Lubbock this afternoon until it was evident
nothing of great import would fire in the area.  Once back on the highway
and heading into OK City that evening we observed many anvil crawlers, CG
and CC.  Reports of tornado/tornados south of OK City came over the radio as
we came within approx:15miles west of the action, but what with darkness,
wet slewn asphalt and weary from lack of sleep last night, we conceeded this
event a big miss.

Outlook for tomorrow looking worrysome thanks to this evening's late deluge.

Fri 5th May, 2001 - a tornado blushed at me today! :D
-----------------

O.M.G.  Today (May 5th) has been amazing!!

Chased with Mark Roscovich, David Ewoldt, Rick Schulze & Bill Wasinger...

YES, we were on the Cordell SC, and YES I got the most incredible footage...
most of the stuff you may see on the news?... FORGET IT!  I have about 6
mins of wonderful, clear capture, from about 400mtrs west of the
touchdown... an elegantly stunning BRIGHT PINK TORNADO!!!!...it was so
breathtaking I actually cried.

May 3 99 was HOOG..... but this was incredibly beautiful.

... most stuff that made TV News, from what we've seen, was from the east,
or south and they missed the beautiful frontlit effect from the sinking
sun... there were chasers ALL OVER this thing.... at least a dozen vehicles
along 183, within a similar vicinity at the time.... touchdown was at
exactly 8.19pm, about 3miles north of Cordell, OK...condensation filled
stove pipe, tracked S to NE for approx 3 and a half mins before receeding
back up into the rapidly dissipating WC.  At its occlucion we were treated
to twin funnels, with a large,newly developing meso to its immediate east
.... rapid development and tightening over 15mins as we tracked east to
follow, intensed rotation with tornado imminent but it then experienced some
kind of strange upburst (?) which blew it nearly entirely apart..... Mark
checked in with a very dejected Jim Leonard, had having tacked SW to a more
southern cell near Manga(?) and missed the late show.

HAVE great video of the blushing tornado, couldn't bear to look away to pick
up my SLR for a couple of stills. Video grabs will be awesome enough!!!

Chaser convergence abounded all day with steak dinner Communion at Denny's
El Rimo, with about 20 chasers including Bill Woolsey, and Gene Roden with
his Norwegian entourage.  (there was another as large gathering elsewhere,
not sure where though) My footage enjoyed replay after replay until the
recorder battery went flat!

Prospects for Sunday looking ..hmmm... OK... but further east OK (which is
lousy chase territory view-wise)..but could be going out with Gene Roden and
couple of others.

P.S. ... our footage now featured on CH4/Storm Track's evening reports, here
in
OK City!

OK, thanks.  There was a cell to the N of here at one stage, so it's possible
there was a funnel north of here, but visibility was poor in this area, very
hazy. :(

Hi all

Am I dreaming, or is that ANOTHER east coast / Tasman sea trough / low
developing?  For us in SA this currently reads another blocking pair and
another week of dry, fine, warm weather as the early season green grass
slowly starts to wither...

[Into drill seargent mode] Come on you miserable little systems, lets get
moving! ;)

<DIV>Hi&nbsp; all, </DIV>
<DIV>&nbsp;</DIV>
<DIV>Just a question about rain events and topography.</DIV>
<DIV>&nbsp;</DIV>
<DIV>The SE flow that has predominated most of today has brought some nice falls 
around Sydney's coastal strip. I was just discussing with Matt Smith in IRC 
about how local topography may interfere with rainfall. For instance, I know 
here in Blaxland we do better with setups where the flow is from the NE 
(usually&nbsp; spring/summer),&nbsp; where the showers come in from the&nbsp;NE 
over the Gosford area. December of 19999 saw many of these types of days where 
western Sydney (Richmond, Penrith, Mt Boyce) would all record really solid 
falls. The showers seem to drift over, then build up at the base of the 
mountains and dump. I have thought this might be due to the typography of the 
showers path. They form offshore, usually with warmish air/sea temps, hit the 
coast near Gosford where its elevated, then off the foothills onto the plains 
east of Windsor and then get lifted again on the lower blue mountains. I was 
wondering if the second lifting process perhaps aided development.</DIV>
<DIV>
<DIV>&nbsp;</DIV>
<DIV>On SE flow days, we get patchy showers. The showers seem to die at 
parramatta. A similar process may be at work here in the reverse with the 
southern highlands and ranges around Appin and Camden. Also whether the cooler 
air actually worked different (it terms of the distance a shower 'cell' can 
travel ) than a warmer air setup.</DIV>
<DIV>&nbsp;</DIV>
<DIV>This topic is one that has been discussed at the NSW ASWA meetings on 
occasions. </DIV>

Michael,

I have just researched the 1972 event. An interesting time indeed. The
tornado occurred on Thursday 17th Feb 1972. Some observations in articles of
the Illawarra Mercury:
- Witness in Oak Flast saw funnel over tree tops lifting trees into the air.
- 3 houses detroyed, 30 damaged to some extent.
- 3 inch hail reported
- one house lifted from foundations, cars spun across yards.
- one person in a weatherboard house reported debris piercing a wall, then
shortly after being sucked back out.
- storm continued on a SE'ly track towards Minnamurra.
- Witnesses at Minnamurra reported seeing clouds converging only feet above
water level before a spin-up which sucked boats up to 10 feet above the
water. There was 5 boats sunk on the river. The spin-up passed over to the
sea without any reported damage.
- Up to 6 water spouts reported as to 80 feet high, where seen at sea north
of Kiama, some petered out as they hit land at blowhole point.

It was speculated by the bom that the weather was partly caused by cyclone
Anthea(?) nearing land in qld forcing a warm/moist airmass south across nsw.

The early part of 1972 was also very interesting weather wise with major
flooding reported from Townsville, Brisbane, Syndey, northern nsw, Bathurst
(which was hit by two big storms in two weeks) and wild weather lead to the
wettest january in the Illawarra since 1918, with 18 inches of rain in
January alone. Interesting times indeed.

Hopefully I'll have some more time later to look for the over events
reported.

Cheers
Andrew

Looks like a couple of possible tornadoes to report of.  Take a look at the 
ABC Weather news site:
http://www.abc.net.au/news/weather/
The first one was near where Michael Bath lives, near Wollongbar in NE NSW 
last night.
The other was near Kalbarri in WA yesterday also.
I'm surprised no one has mentioned anything on this list yet..
Hector..

Hi John Gaul

Sounds like you're being a bit modest with your weather down there, John,
judging by the following comment in 

http://www.abc.net.au/news/weather/weath-7may2001-1.htm

about the stormy conditions near Wollongbar.

"I've been on a holiday to New Zealand," Mrs Martin said. "Tonight, I feel
like I am back in New Zealand again."


Cheers

out today from one of the kids on my schoolbus that her horse was killed in
this storm by a lightning strike. You never know when you are the

Hi Hector welcome to the list, where are you from ?

I spoke to Michael earlier today and he suggested it was a localised gust of
strong wind. Could have been a micrburst or something.  He will be able to tell
people more though. All it seemed to do was take the roof off a servo which in
turn caused damage as it hit buildings. Still interesting.

Also got an email from Roger Hill (a US chaser) he has seen 6 tornadoes in the
past 2 weeks.

Hector has been lurking around for some time but won't reveal himself. Will
you Hector? Hector is a regular on the Weatherzone forum and we suspect he
is a storm chaser from NSW. Are we close Hector?

She was referring to the amount of hail which looked like snow.

I was interviewed on ABC North Coast for a news grab (which aired at 1230 
and 1730 but not put on their website) refuting the tornado theory based on 
what I observed (approaching the cell from its western flank, during the 
storm and today).

The service station is very exposed to the south, two roller doors to the 
workshop blew in then the roof lifted off and flew back (northwards) over 
one property and into the next were there are two-story townhouses. 
Extensive damage was caused by an I-beam attached to the metal roofing.

I had a detailed survey this afternoon and there is no evidence of major 
damage like at the service station. Some small branches were off trees, but 
the most obvious thing was the leaf litter from all the hail. This was over 
at least a 5km long SW-NE track.

Yes the HAIL !!  I was out after 1pm and there were drifts of hail in 
several locations, but particularly in one culvert on the Bruxner Highway 
between Wollongbar and Alstonville. It was up to 30cm deep in patches and 
looked like snow against the green grass. The stones were mostly 1-1.5cm 
diameter, but also many were in the 2-2.5cm range. And these had been 
exposed to full sun for at least 5 hours.

Hector is not someone else? He is Paul Graham ?

Why are you using 2 names for Paul ?

BTW does anyone know exactly where the waterspouts were the other day in Sydney,
and how many there were?
Thankyou

As Phil mentioned most models are entertaining another slow moving Tasman
sea low. It is a bit like a caged tiger, and the cage is barely bigger
enough to move in. The low really does not have anywhere to go, so the
slightest change in the high pressure systems will see it either drifting
off to New Zealand or coming closer to the NSW coast. In an almost identical
scenario last week the low failed to move closer to the coast and expected
rainfalls disappeared.

The question is will this low suffer the same fate.

GASP & MRF are going for the low to be bounced back to the NSW coast,
actually increasing rains towards the end of the week.

AVN and NGP are going for enough weakening of the high over New Zealand for
the low to slowly drift towards the tip of the north island.

ECMWF has an interesting scenario for Wednesday with a smaller low forming
just off the Hunter coast, this may indeed introduce some interesting
weather. This low merges with the larger one on Thursday and drifts it all
east by the weekend.

Either way I think the Hunter area may get some flooding.

This is very interesting Andrew, thanks for the information. The other
interesting aspect is that in February the lake Illawarra water is at a
maximum.

In theory the storm can move over the lake near Dapto and have a 5km stretch
of very warm water before hitting Oak Flats.

Hi Michael and all,

Studying the AVN models is interesting as well. It predicts that by around 
Thursday the winds will be onshore say at least above the surface and well 
onshore SE winds through to the mid-layers. The temperatures at 500hPa 
suggests that another cold pool is coming across and should re-intensify 
the rain activity from Sydney but particularly the Illawarra about Thursday 
06Z. There also seems to be a cloud and associated rain band developing as 
part of the approaching cold pool slightly inland around Bathurst-Orange. 
Quite and interesting scenario indeed. This picture seems to fit in with a 
low that moves SSW with the intense region gradually centring over the 
Illawarra during Thursday. This is consistent with typical flooding rains 
in the past during August of some years.

<DIV><FONT size=2>Hi Dann</FONT></DIV>
<DIV><FONT size=2></FONT>&nbsp;</DIV>
<DIV><FONT size=2>The discussion you raise could well be as complex as the 
supercell we just had on the list. In short there are no hard rules and every 
situation is individual...to a degree.</FONT></DIV>
<DIV><FONT size=2></FONT>&nbsp;</DIV>
<DIV><FONT size=2>Much of the trouble with SE flows is that we are looking at 
stabilising weather the further west you go - closer to high pressure. With 
showers from the NE you are often looking at unstable weather to your west, 
therefore showers along the ranges.&nbsp; Todays situation is typical of Tasman 
Sea lows, rainfall tapers very quickly away from the coast as the rain is often 
in a tight circulation around the low.</FONT></DIV>
<DIV><FONT size=2></FONT>&nbsp;</DIV>
<DIV><FONT size=2>However topography does play a part. Even here in the Southern 
Illawarra we do remarkably poorly in SE or S situations. The coast line from 
Kiama to Wollongong runs very N/S , the showers often run in the same direction. 
Add to that a shadow affect from Mount Saddleback near Kiama and we are often 
left with drizzle at best.</FONT></DIV>
<DIV><FONT size=2></FONT>&nbsp;</DIV>
<DIV><FONT size=2>During showers and rain from the NE the opposite occurs, we 
can get a decent offshore run along the coast from&nbsp; Port Hacking to almost 
Kiama before the showers run ashore, then add to that the lifting along the 
southern escarpment and the totals add quickly. You can often during these 
events a look at the radar and see heavy rain around Coffs Harbour, then lighter 
stuff until you get to Wollongong.</FONT></DIV>

  <DIV>Hi&nbsp; all, </DIV>
  <DIV>&nbsp;</DIV>
  <DIV>Just a question about rain events and topography.</DIV>
  <DIV>&nbsp;</DIV>
  <DIV>The SE flow that has predominated most of today has brought some nice 
  falls around Sydney's coastal strip. I was just discussing with Matt Smith in 
  IRC about how local topography may interfere with rainfall. For instance, I 
  know here in Blaxland we do better with setups where the flow is from the NE 
  (usually&nbsp; spring/summer),&nbsp; where the showers come in from 
  the&nbsp;NE over the Gosford area. December of 19999 saw many of these types 
  of days where western Sydney (Richmond, Penrith, Mt Boyce) would all record 
  really solid falls. The showers seem to drift over, then build up at the base 
  of the mountains and dump. I have thought this might be due to the typography 
  of the showers path. They form offshore, usually with warmish air/sea temps, 
  hit the coast near Gosford where its elevated, then off the foothills onto the 
  plains east of Windsor and then get lifted again on the lower blue mountains. 
  I was wondering if the second lifting process perhaps aided development.</DIV>
  <DIV>
  <DIV>&nbsp;</DIV>
  <DIV>On SE flow days, we get patchy showers. The showers seem to die at 
  parramatta. A similar process may be at work here in the reverse with the 
  southern highlands and ranges around Appin and Camden. Also whether the cooler 
  air actually worked different (it terms of the distance a shower 'cell' can 
  travel ) than a warmer air setup.</DIV>
  <DIV>&nbsp;</DIV>
  <DIV>This topic is one that has been discussed at the NSW ASWA meetings on 
  occasions. </DIV>

Yes Jimmy, very interesting times ahead.

Today's weather was light drizzly showers all day, perhaps just 2-3mm, but
windy, cold and miserable. I love it !!!

I wouldn't have a clue where she may have been. The only recent tornado was
in Cobden, Greymouth on  the March 28th. 
Was that the storm she may of referring to???

There's no other weather happening here.

It is so boringly settled here at the moment, as per normal for the time of
year!

Hi all,

Yesterday I was fortunate enough to get a nice little funnel under a
rotating base of a hailstorm near Beaudesert!  Also a few other nice

Hi all,

Check out these:

I'll have most of my pictures later today.

If people have the chance, it is well worth taking a look at the models,
which are obviously suffering a serious case of chaos for the next week over
southern Australia. The models are in general consensus for an unsettled
rather blocked period of weather, but are having great difficulty in
deciding where to place lows and troughs.

Against this backdrop of uncertainty, there is the suggestion of a
significant low developing near Victoria/Tasmania next week with thickness
values sufficiently low for a major snow event. Certainly all well worth
watching...

Cheers,

David.

It's amazing that a thunderstorm could be so well monitored that it could be
considered to have a history. We don't have the technology to track storms
with that degree of resolution.

Doesn't seem to be anything nasty to me. No attachments or anything. Maybe it 
is just picking up the subject as a suspicious. All lower case and contains 
the words "pics".

The issue of warnings on the NSW North Coast regarding STC Donald have 
received a lot of media attention around here, and been pushed by our NSW 
Member for Ballina Don Page since it hit on 8th March.

Apparently the Sydney BoM have agreed to review the way warnings are 
handled for these type of systems, providing more detail and emphasis to 
the dangers to media outlets like radio to broadcast. I haven't heard about 
the exact detail but perhaps the warnings will be quite similar to those 
for TCs, but without using the magic word "topical cyclone" ...

Hi folk,

Yes, we tend to get good rain when the wind funnels through the Grose
Valley, which is basically north east. In this current event I have had 21mm
so far, a fair bit of that (11mm) though was from the convective event on
Saturday where we had some thunder etc. Other than that its been mostly
light to heavy drizzle from the south/south-east with the odd burst of rain.

Been cool though. My max temps are: Saturday 13 (around 10 for most of the
day though), Sunday 7.5, Monday 8.5, and probably another single figure day
on the way today.

Thanks Daniel and Michael for your thoughts on rain/topography, I enjoyed
it. And as for this refreshing, cool, moist weather, I think Maxwell Smart
said it best, "And...loving it!'

Hi Dann

The discussion you raise could well be as complex as the supercell we just
had on the list. In short there are no hard rules and every situation is
individual...to a degree.

Much of the trouble with SE flows is that we are looking at stabilising
weather the further west you go - closer to high pressure. With showers from
the NE you are often looking at unstable weather to your west, therefore
showers along the ranges.  Todays situation is typical of Tasman Sea lows,
rainfall tapers very quickly away from the coast as the rain is often in a
tight circulation around the low.

However topography does play a part. Even here in the Southern Illawarra we
do remarkably poorly in SE or S situations. The coast line from Kiama to
Wollongong runs very N/S , the showers often run in the same direction. Add
to that a shadow affect from Mount Saddleback near Kiama and we are often
left with drizzle at best.

During showers and rain from the NE the opposite occurs, we can get a decent
offshore run along the coast from  Port Hacking to almost Kiama before the
showers run ashore, then add to that the lifting along the southern
escarpment and the totals add quickly. You can often during these events a
look at the radar and see heavy rain around Coffs Harbour, then lighter
stuff until you get to Wollongong.

G'day Dave and all,

Yes, this is the time when folk like me tend to come out of hibernation. The
models are certainly giving mixed messages. I like the look of that
potential front coming through for next week although a number of  folk on
snoinfo forum are saying this current blocking pattern is not good for
frontal development...hmm. Didn't we have a decent blocking pattern this
time last year and then a couple of weeks later that monster, meridional
high combined with a nice low in the Tasman to feed frigid air into the
south-east for days?

I like the experimental Bom charts out to 7 days, they show a nice sub 540
cold pool over the south-east for Monday. Does anyone have any comments on
the reliability of this experimental setup?

Cheers,

GASP is generally good for about 4 days in my experience, after that it gets

They would both indicate a low developing off the Hunter/Sydney coast at

See what happens I guess !

HI Lindsay and all..

Im not experiencied enough yet to really give my comments on models... I do
remember though 28th May last year where Orange,Bathurst Oberon had a
dumping of snow upto 4 ft in Orange and surrounding areas..   To many
others here on list, we hope it all happens again just as good.. For me
just means more work as blackouts galore happened last year.   All i can
say is BRING IT ON.

As the same last year, will provide road closure reports around my area via
radio scanner..

Dave
Bathurst..

Hi all,

Last night it was looking quite likely that the Sydney and southern areas 
were in for a drenching based on the AVN. Now it has decided that the winds 
will not be as onshore as first thought. Oh well just a model. Amazing 
change in just 24 hours. Nevertheless, there will be a fair amount of 
coastal shower activity and continuing cold conditions extending further up 
the coast.

Hi Matt

What is really interesting is the increased amount cloud coming into
circulation around the east and south of the low.

I am going out on a limb and suggesting on present course this cloud set to
come ashore Sydney / Illawarra sometime around 12am -2am tonight.

The Weather Channel animation shows it really well. The main spiral that is
500km offshore or so is heading this way and not looking like breaking up.
This is very different in some ways to the cloud mass that has been
affecting the Hunter / Mid North Coast, this is a large mass sourced from
the north Tasman. Unless it turns 90' in the next 500kms I see an increase
in rainfall overnight.

I haven't the time to investigate but its as if the NE quadrant of the low
tapped into nice moisture, actually there was a cloud band coming in from
the NW near the north of New Zealand, it's as if this low has entrained
this.
Michael

Matt and Michael

The fetch of this cloudmass is quite staggering, and can be best seen
on the Tasman satpic at
ftp://ws-ftp1.afwa.af.mil/metsat/current/agm5mb02.gif -- a mass of
very active cloud extends from about 500km east of Sydney all the way
to the east and southeast of Fiji. I agree that it would seem unlikely
that it *won't* give the Illawarra and Central Coasts some decent
falls overnight.

Norah Head has had 51.2mm in the 3 hours to 7pm, for a total of 102.8
since 9am.

ASWA - Victoria

Meeting held: April 21 at the Pancake Parlour in Doncaster

Present: Robert Goler, Andrew McDonald, Blair Trewin, Lindsay Smail,
Clyve Herbert, Rod Aikman, Dane Newman, Simon Borg, Debbie Parker, Paul
Yole, Luke Garde, Kevin Garde, Bill, Mel, Tony Middleton, Matt Smith
(NSW), Matt Pearce (NSW), Anthony Cornelius (Qld), Nick Sykes, Harald
Richter, Jane ONeill

Introduction of interstate members

Anthony Cornelius was invited to speak on his favourite topic:-
"The effect of a geostrophic flow during a left moving supercell and
what effect the isallobaric wind has on the agriclimatatology of SE
Queensland with special reference to the diminished superadiabatic
potential of paddocks with more than 10 degrees slope towards true
magnetic north."
but the invitation was declined due to the lack of time.

ASWA car stickers as well as posters from Lindsay Smail (Geelong Weather
Services) available

Group discussion of previous month's weather (lows during mid March)

**********
Guest speaker: Harald Richter
Topic: Big Bad Thunderstorms - when do they form? what do they look
like?

What is storm chasing? (brief notes)

Where can you chase storms?
(the area available increases as you go north from Melbourne) Some
regions are more favourable dependant up on latitude, proximity to
mountain chains, warm oceans, land masses generating convection. US
Plains, southern China, northern Argentina, Bangladesh.

When can you chase storms?
If it is too hold or too cold you will not get severe storms. The right
ingredients tend to favour spring.

Why would you chase storms?
People 'chase' for different reasons: adrenaline rush, structure,
process etc

4 key ingredients - if any of these are missing you don't get a severe
storm.
- moisture
- instability
- lift
- shear

Forecasting is the most important element of storm chasing - you need to
get your target area right. Deep towers tend to form in between other
moist parcels rather on the edges of the target area, as here there will
be mixing of dry air into the moist area.  The 'nose' of the moisture
tends to be where the severe weather occurs.  To check the depth &
condition of the boundary layer in Victoria check the temperature & dew
point for Melbourne, Dunns Hill & Mt Hotham.

A great discussion followed by some wonderful video footage taken by
Harald during his stay in the US.

We'd like to thank Harald for joining us & sharing some of his knowledge
(especially the practical bits with video) and look forward to joining
him during some of his lectures around Melbourne in the next few months.

**********

Next meeting: Saturday May 19th at 8.30am

Discussion topics: April rain event / wave low formation

Guest speaker: Rob Gell
Topic: "...and what does 'Fine' really mean?"

Hi Michael.
Are you going to stay up? and wait for the rain to start, things should get
interesting along the section of coast where this cloud mass makes landfall,
if it holds together.regards Clyve H.

Hi Dann,

I agree with Michael Thompson, this could potentially become as complex
as the recent supercell discussion!

But certainly, topography can make and break a potential shower or rain
event.  For example, one of the main reasons we get showers during
SE'lies along the east coast is due to the convergence zone between the
land and ocean.  Because the friction to the ocean (30%) is much less
than land (70%), you actually get a convergence zone that exists along
the coast.  This aids in coastal shower development, especially if you
have strong SE'lies and a bit of supporting cold air somewhere in the
middle atmosphere.  This convergence works best if the wind is
orthogonal to the coastline.  For instance, the NSW coast faces SE so
SE'lies winds provide the best coastal shower/rain events along the
coastal areas due to its alignment.  Starting from SE QLD, it's slightly
different though, as the curvature of the coast changes.  Hence our best
rain events tend to occur if we have E to ENE winds due to the alignment
of the coast.  Brisbane though is less exposed then say the Gold or
Sunshine Coasts, because of Moreton Bay and the islands.  This causes a
convergence zone out to sea first, so coastal showers tend to form near
the islands before moving towards the coast and often collapsing along
the coastal suburbs.  If we get E'lies or ENE'lies - these showers tend
to last longer.

However, the other thing to remember with SE'lies vs NE'lies is the
different sorts of airmasses and instability associated with them. 
You're going to get a much more warm and humid airmass with NE'lies,
hence (if we were to ignore upper levels), would give a slightly more
unstable atmosphere, helping the showers out and continue to grow. 
Also, SE'lies tend to have large DP fluctuations the further you go
inland (ie it dries out quickly), so this could have something to do
with showers dying out over certain regions - you do see similar
patterns in Brisbane - but it's difficult to get a feel for the extent
of it, as most coastal showers do not show up on radar due to the
underestimating effects of it.  However the Archerfield area does seem
to be a boundary of which most decent coastal showers will collapse
(from many coastal shower 'chases.')  It is not (in my opinion) a
coincidence that DP's tend to drop significantly between Archerfield and
Amberly on SE'ly days.

Mountains also play a huge factor in rainfall - just look at the effect
the Eastern Highlands has on central/western NSW and QLD!  Much drier. 
The reason for this tends to be if very moist winds do prevail, they
tend to cause thunderstorms/showers on the ranges.  This is due to a)
Convergence once more, b) orographic lift, c) elevated heating.  I'll
explain these soon.  But if moist air moves over mountains and clouds
condense from it, it loses moisture.  Once the air moves away from the
mountains on the other side, it sinks and warms (it is a dry parcel of
air, and it will sink and warm at the Dry Adiabatic Lapse Rate - DALR). 
This effect is not overly noticable in Australia though, as our
mountains aren't really that high enough.  Places like Death Valley
though in the US tend to experience hot and dry conditions because of
these.  Basically, the air is warmer then it started with because lets
take two figures, 5c/km for the SALR (Saturated Adiabatic Lapse Rate),
and 10c/km for the DALR.  Note the DALR is constant, but the SALR
fluctuates, but we'll assume it's constant here.

Lets say a parcel at 0m is forced to rise over a mountain range of
5000m.  Lets say it condenses at 1000m.  The parcel is 20C.  This
ascends at the DALR to 1000m, and is now 10C.  It is now saturated and
warms at the SALR (as the latent heat released by the moisture within
the air parcel contributes extra heat so it cools at a slower rate).  It
now cools at 5c/km for 4000m.  So it's -10C (remember, we're assuming
the SALR is constant when actually the SALR eventually tends to the DALR
as the physical quantity of water vapour in the parcel reduces).  It now
has to fall back to 0m after it crosses the range.  Because the parcel
is <100% RH, it now warms at the DALR.  Remember - air cools as it rises
because it expands, and there is the same amount of heat over a larger
volume.  The oppositite occurs as it sinks, because it shrinks and there
is the same amount of heat over a smaller volume.  It will now cool for
5km at 10C/km, so the new temperature at 0m because the parcel has dried
out significantly is 40C!  This is just a hypothetical example, but it
illustrates why often if you have a mountain range, the side towards
prevailing winds is moist, and the side away from the prevailing winds
is hot and dry.

Coming back to how ranges/mountains induce rain/cloud development - the
first one is the same process as to why we have convergence zones on the
ocean/land boundaries.  Simply air is forced to slow down as it
approaches a larger obstacle with greater friction values.  Next is the
orographic lift - the air must go *somewhere*, and it's forced to rise
with the slope.  This is an important initiation sometimes in
thunderstorms on the ranges.  The other is elevated heating.  By
elevated heating, I mean this - we often have surface stations near the
ocean about 50m above sea level.  Lets say it's 30C at sea level, and
-20C  at  500mb (whoa!!!)  If we take the 500mb level to be 6000m, that's a
50C drop in 6000m, or 8.3C/km drop (gotta love making up your own
figures :)  
What if it was 30C on the ranges?  This can happen - sometimes there's
only a small drop in temperature on the ranges - it really depends.  If
there is strong heat/moisture advection then the difference between the
ranges and the surface may not be as noticable.  We'll assume it's equal
for this example.  So that a 50C drop, but now instead of over 6000m,
it's over 5000m!  So your lapse rate increases to 10C/km (can see Macca
drooling already).  Of course, this is just hypothetical.  But it
illustrates how elevated heating means our surface parcels on the ranges
'see' the cold air much sooner then surface parcels near sea level
would.  This is a significant factor in areas of high elevation, but
still get very warm and humid.

So these are some methods of how the ranges effect rainfall - both on
the side of the prevailing winds, and the leeward side.  

I know that the ranges along the QLD coast results in much higher TC
rainfall (well IMO), then say the WA coast.  As the ranges provide a
great lifting zone, with gale force/cyclonic winds - there'd be a hell
of a lot of lifting due to orographic and convergent effects - thus more
condensation/clouds - and more rain.  All of the major rain events
generally are recorded on the ranges (ie, highest totals), or very close
to them.  This goes for anywhere, not just the QLD coast.

I think local topography will be one of the major variability factors in
mesoscale forecasting (ie, thunderstorms etc).  As sometimes a range or
mountain and be in such a position as to redirect the low level flow
into a storm, perhaps weakening it, or perhaps strengthening it.  Then
comes discussion into lee-vorticies and waves from mountains - and the
possible effects they might have on thunderstorms.  

Interesting dicussion though - as to your real question, I don't know
because I'm not a Sydney-sider (and who would want to be after the
THRASHING Queensland gave NSW!!!  QUEENSLANDER!!!!!!!!!!!!!!!! :-)

On that note, I had better sign off!

I have just driven home from Hong Kong Island and all the way watched the 
most magnificent display of distant anvil-crawlers I've seen in a while.
That part of the sky was just flickering away like a giant arc welder.
It's currently measured at 127 strokes per minute and still about 150 Km 
from here according to the lightning detector on Clarence's roof (see 
paste below) which anyone can check at 
http://www.weather.org.hk/lightning/ whenever you like.
The real beauty is that it is headed exactly this way.
Fair dinkum I had thought I was going to have to open a branch of one of 
John Gaul's associations over here the way the weather has been: hot and 
boring every day.
But the relief is here at last!

Hi all,

Apologies for asking a stupid question...but I've always wondered,
exactly what does the sky look like when GMSD seems to have such a nice
line moving over, yet there's nothing on radar?  For example...current
GMSD is a good example, I would have always imagined there to be showers
at least, but I've seen many cases when this is certainly not the case! 
And I was just curious as to what the sky does look like during those
times...

I'll shutup now...

Hi all, a few points.

1/ Hey Anthony, loved your note on topography etc, it certainly wasn't
boring, although I will have to go back and re-read it :)

2/ Macca, nah, it wasn't frog talking about the blocking patterns on snoinfo
although he has just surfaced again and started croaking. Why are you
banned?

3/ Jane, your sense of humour is wonderful! :) I have a funny story about
someone cornering me in Katoomba recently and telling me that the climate is
on a downturn and that we are now going through a very cold phase, its too
long for here but it was very funny although I felt a bit frustrated too.
She was very serious. Knew I shouldn't have mentioned my interest in snow to
her...

Finally.

4/ Someone has posted me and asked me more about Thickness and what
thickness might be needed to obtain snow at sea-level in say, Sydney, or
even Melbourne. Also, what method is used to calculate this? I'd appreciate
your help, folk. I've given him an initial reply but indicated there are
others that could explain it better than me. I know its not only thickness
that indicates the chances of snow, but its a start in the learning process.

Cheers,

Lindsay Pearce
PS: Approaching four days here now with the mercury not rising into double
figures - great!

Hi all,

Apologies for asking a stupid question...but I've always wondered,
exactly what does the sky look like when GMSD seems to have such a nice
line moving over, yet there's nothing on radar?  For example...current
GMSD is a good example, I would have always imagined there to be showers
at least, but I've seen many cases when this is certainly not the case! 
And I was just curious as to what the sky does look like during those
times...

I'll shutup now...

Hi Anthony,

Not sure about Melbournites, but I've just witnessed a most amazing 
transformation here in Wycheproof atm! (11.32 a.m.) In a matter of ten 
minutes the sky has gone from completely clear and sunny to mildly overcast 
but only at mid-levels! It has formed overhead and not been advected and is 
travelling quite noticeably south - north! Surface winds are negligible. 
Cloud has wavelike formations in it. The cloud deck appears to be 
continuously forming just south of Wycheproof, moving north, then 
evaporating again to the north of town. Hard to estimate altitude of deck - 
perhaps 1000 m? Interesting to me anyway!
:))

Cheers,
Kevin from (a very dry) Wycheproof.

Could everyone who has a webcam for weather please post the address? It is 
always interesting to go storm chasing on the internet.... :-)

Maybe we need a page one of the club sites with a map and the links.

<DIV></DIV>&gt;ASWA - Victoria 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Meeting held: April 21 at the Pancake Parlour in Doncaster 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Present: Robert Goler, Andrew McDonald, Blair Trewin, Lindsay Smail, 
<DIV></DIV>&gt;Clyve Herbert, Rod Aikman, Dane Newman, Simon Borg, Debbie Parker, Paul

<DIV></DIV>&gt;Richter, Jane ONeill 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Introduction of interstate members 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Anthony Cornelius was invited to speak on his favourite topic:- 
<DIV></DIV>&gt;"The effect of a geostrophic flow during a left moving supercell and 
<DIV></DIV>&gt;what effect the isallobaric wind has on the agriclimatatology of SE 
<DIV></DIV>&gt;Queensland with special reference to the diminished superadiabatic 
<DIV></DIV>&gt;potential of paddocks with more than 10 degrees slope towards true 
<DIV></DIV>&gt;magnetic north." 
<DIV></DIV>&gt;but the invitation was declined due to the lack of time. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;ASWA car stickers as well as posters from Lindsay Smail (Geelong Weather 
<DIV></DIV>&gt;Services) available 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Group discussion of previous month's weather (lows during mid March) 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;********** 
<DIV></DIV>&gt;Guest speaker: Harald Richter 
<DIV></DIV>&gt;Topic: Big Bad Thunderstorms - when do they form? what do they look 
<DIV></DIV>&gt;like? 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;What is storm chasing? (brief notes) 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Where can you chase storms? 
<DIV></DIV>&gt;(the area available increases as you go north from Melbourne) Some 
<DIV></DIV>&gt;regions are more favourable dependant up on latitude, proximity to 
<DIV></DIV>&gt;mountain chains, warm oceans, land masses generating convection. US 
<DIV></DIV>&gt;Plains, southern China, northern Argentina, Bangladesh. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;When can you chase storms? 
<DIV></DIV>&gt;If it is too hold or too cold you will not get severe storms. The right 
<DIV></DIV>&gt;ingredients tend to favour spring. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Why would you chase storms? 
<DIV></DIV>&gt;People 'chase' for different reasons: adrenaline rush, structure, 
<DIV></DIV>&gt;process etc 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;4 key ingredients - if any of these are missing you don't get a severe 
<DIV></DIV>&gt;storm. 
<DIV></DIV>&gt;- moisture 
<DIV></DIV>&gt;- instability 
<DIV></DIV>&gt;- lift 
<DIV></DIV>&gt;- shear 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Forecasting is the most important element of storm chasing - you need to 
<DIV></DIV>&gt;get your target area right. Deep towers tend to form in between other 
<DIV></DIV>&gt;moist parcels rather on the edges of the target area, as here there will 
<DIV></DIV>&gt;be mixing of dry air into the moist area. The 'nose' of the moisture 
<DIV></DIV>&gt;tends to be where the severe weather occurs. To check the depth &amp; 
<DIV></DIV>&gt;condition of the boundary layer in Victoria check the temperature &amp; dew 
<DIV></DIV>&gt;point for Melbourne, Dunns Hill &amp; Mt Hotham. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;A great discussion followed by some wonderful video footage taken by 
<DIV></DIV>&gt;Harald during his stay in the US. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;We'd like to thank Harald for joining us &amp; sharing some of his knowledge 
<DIV></DIV>&gt;(especially the practical bits with video) and look forward to joining 
<DIV></DIV>&gt;him during some of his lectures around Melbourne in the next few months. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;********** 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Next meeting: Saturday May 19th at 8.30am 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Discussion topics: April rain event / wave low formation

Hi All.

You will find my latest experimental colour enhanced satpics at :
http://users.ace-net.com.au/~carls/ImagesTemp/aunzir200105081431.gif
http://users.ace-net.com.au/~carls/ImagesTemp/SCS-200105081431.gif

The first image is a large area one showing the developing low off the east
coast and reveals the ex-equatorial moisture feed that is sustaining it
that was mentioned in an earlier post.

The second one is of Tropical Depression 03W entering the South China Sea -
this could become a reasonable sized cyclone and looks like it is headed
closer to Hong Kong - and also shows the severe thunderstorm Phil mentioned
last night as it was approaching Hong Kong from the NE (speckled light blue
oval with thin pink boundary).

These images from clipped from FNMOC satpics use a purpose designed colour
table to maximise the details in the image. Your browser may use pre-set
colours and dithering to approximate the image colours. For best results,
download them into your computer and use a quality graphics program that
checks and uses the image colour table - perhaps setting up a paint
document of the right size with a depth of millions of colours and
importing the image could give you the best results.

Regards,
Carl.

Hi all,

I've finally uploaded my Darling Downs chase - a nice little wall cloud
developed under a nice circular updraft!  As well as a small (mid
level?) funnel nearby.  I thought the guster looked quite mean as it
approached, also got slammed in by a severe microburst - the URL is:

There's one at the bottom of here but don't expect the Melbourne Webcam -

Hi David,

I'm actually in the process of building a website purely for weather
webcams/webcams with a good view of the sky.  I hope to have it finished by
August, and the URL will be virtualchaser.com (which transfers you to the
new BSCH URL for now)

Just let me to do a forecast !!!

I just can't believe the way this cloud fell apart.

It even had the cheek to push through some remnants of cirrus and middle
layer junk from the SE early this morning.

Great blobs of the cloud actually sheared off to the south ( of all
directions ) about 500km out.

Most of the models have backed away from this low doing anything more to
Australia.

Hi all.
A rather impressive field of cold air just getting into southwest WA,what
looks better though is a large grouping of enhanced cold CB's well south of
WA, concentrated near a vorticity region within a 500hpa thermal trough,
this region may generate a new low over the next 6 to 12 hours. regards
Clyve Herbert.

G'day All,

I'm a little confused? I thought the High Pressure
Band should be drifting further North this time of
year? We seem to be experiencing more of a summer
pattern now than we did during the summer months!
"Nice" weather is lovely...but Tassie certainly needs
some good seasonal rain. I know the forecast models
don't look good in this respect, but the weather is
dynamic...so I'm hoping it will prove them wrong!

All,

I find it a bit strange that the BoM has persisted with their forecast
of 'scattered showers' today for the Illawarra in their midday forecast.

This is despite the fact that it has been a fine sunny morning with no
more than 3/8 cloud cover and a S/SW wind as opposed to a SEly.

Can't see it!

Andrew.

Andrew,

Yes, it's often frustrating during Autumn when you're aching for the
highs to bugger off up north, and the models begin to show some promise
of that happening, and then it all gets dashed with a dirty great big
one showing up at your latitude (Tas)!

I think the ST ridge is slowly getting there but it's always a bit shady
at this time of year. It makes you shudder at the thought of getting
another winter like 1999 where the ridge generally stayed south for the
whole season, blocking any potential 'antarctic' cold outbreaks - that
winter was (mostly) a fizzer!

Andrew.

system stuffed up and I couldn't send/receive any emails. As soon as I
deleted the email I was going to send you, my email server started working
again...hmmm.

I've had some strange things happen today, crossed lines, funny connections
to the net etc.

Hi Clyve,

This is in the Notes on Weather from the BoM,  at  1600 WST 10/05/01,

FUTURE DEVELOPMENTS:
The cold front is expected to amplify on Saturday as it nears the SW with a
low
forming just to the south of Albany by Saturday night. Showers with some
heavy
falls, thunderstorms and hail are likely in the Lower SW. Showers should
reach
other parts with light to moderate falls.
The low should move south of Esperance towards the Bight during Sunday. As a
result showers with some heavy falls are expected in southeastern parts and
along the western south coast. Mostly moderate falls in other parts though
showers should clear the central west and lower west coasts later. Cold to
cool
conditions are expected in most parts.
The low should continue eastwards across waters south of the Bight during
Monday. Showers should continue in south coastal parts, although become
lighter
and more scattered. It should be fine elsewhere, with a cold night, and
local
frosts.

They have been forecasting this for the last fewday's and from all account's
alot of the Models that the BoM use have more aless all fallen in line with
each other, with some to a lesser degree that the other ones. But we shall
see what happens in the next 24 Hrs as we get closer to the day concerned.
Hope it does happen it should end up being a very interesting day :):), Hail
and T/Storms would be good. What are your thoughts on a possible " Coldie "
cold air tornado with this system passing through over the early part of the
weekend ?.

Hello Everyone,

There were problems in the Asia Australia region yesterday. Still unknown
what they were.  We had troubles reaching the WAN (wide area network) over
the internet. in Australia and Japan yesterday.

I think there are still problems but not as bad.

I think it's tied into how often the forecasts are actually reviewed.

Both Illawarra and Hunter have scattered showers forecast, whilst Sydney
sandwiched between both has ' the chance of a shower near the coast '

However there does appear to be an interesting cloud field south of the
Illawarra around sunset. It looked very much like it was showery further
down the coast.

Thanks Anthony, much of what you are referring to is back up by radar
patterns I see all the time.

For example the convergence zone you refer to - how many times have we all
looked out the window in Sydney / Illawarra and seen showers along the
coast. We tend to think of the ocean being a boundary to another air mass,
but look at the radar pics and how often are those showers streaming up the
coast  just in a band 50 -100km wide.

In the Illawarra, especially Spring - Early Summer it can actually be up 5C
warmer at 700m at Bowral then the coastline. The sea breeze combined with
the Illawarra escarpment make a beautiful inversion. If you want to see such
an inversion simply look at this photo.
http://ozthunder.com/chase/inver.jpg
at first it appears that you are looking at the ocean, in fact the level
line is the seabreeze inversion.

Yeah i think the Illawarra escarpment is a great place to witness some great
examples of rain-topographic effects. I remember when Matt Pearce, Matt
Smith and myself met up on a little chaser convergence at Bulli Pass,
thinking back to the flash floods that occured there a few years ago. We
marvelled at how close the top of the pass was to the ocean. We pictured the
moist  SE winds pushing up into this bowl type formation and dumping its
load.

Its a truly awesome spot.

Hi all.
This is a very interesting photo,especially seeing that this waterspout is
very close to a populated area,although small the waterspout is relative to
the congesting cumulus,this was an interesting day with a light southeast
flow and rather mild(about 18c). The lower layers were very moist and
unstable with deep low level convection, cu  bases  were around 300m and
tops to about 3000m,there was a weak inversion at about 2000m,lapse rates
were very steep in the lower 3000m, but the cu  appears to  have been driven
more through the condensation process than strong surface heating. The
previous day there was a weak vorticity centre just west of Mt Gambier,this
low level system may have moved just north of central Victoria on
Sunday.regards Clyve Herbert.

Hi Anthony.
The reflectivity of high and thick cirrus is well known, and we get lots of
it here in southern Vic, especially in the vicinity of cold fronts
undergoing frontolysis,I also have wondered not about the occurrence of
showers at the surface but what it would be like to stand within the thick
cirrus streamers and what sought of precipitation it would be,last night the
cirrus tops were about 30.000ft or so with virga reaching about 23 to
25,000ft then subliming, below that there was nothing except haze.regards

Hi Eastcoasters.
An interesting comment about the fetch of the present cloud band coming
ashore on the central NSW coast. An interesting comparison can be made with
a similar cloud band that wrapped around the developing low over Victoria on
the 21 April 2001 and brought record 24hr/48hr/72hr and monthly record
totals to the Geelong area, on that occasion the cloud band had a similar
extent.Regards Clyve

There have several very extraordinary rain events in the Illawarra.

The most recent,  August 1998 http://ozthunder.com/diary/w98.htm#17AUG

Then there was the Dapto flood back in the 1980's in which 700mm approx fell
in 18 hours on the escarpment.

The key to all is not SE flow, but NE.

Clyve,

Your observation of cloud height is interesting.  I played tennis in Port
Melbourne on Sunday afternoon and sent an SMS to Anthony saying that the Cu
out to the W were looking very interesting.  From where I was, some of the
tops looked to hit about 15,000ft and even some very weak glaciation occured
on some.  Updrafts were visually fairly crisp and dare I say it but had I
not played tennis, I would've gone for a drive.

While being surprised to hear the report, I was not as surprised as I
would've been had I not seen that line of Cu.

I agree with you how close that spout is to the centre of Lorne itself.
Knowing the area very well, I'd say that spout is no more than 100m from the
beach at Lorne and probably sitting about 3-400m E of the surf life saving
club, putting it merely 2-300m from the main street.  Given that it was
moving in a S'ly direction, I am surprised that no damage was reported and
also that it isn't the talk of the town.

Regards,

Andrew McDonald

Hi Bussie and All

>Very nice. Blues, yellows and light greens mean some action? Hey I'm still a
>learner :-))
>Bussie (Rutherglen NE Victoria)

Yes, I'm a bit of a learner with these too (it is experimental after all :-).

The colour table preserves the relative brightness level of the original
greyscale image and adds the colours, which does have some effect on the
apparent brightness, however in general you can say that the lighter the
shade of a colour is the colder the cloud is at that point, and the hues
run through blue-green-red-blue in steps of 5 degrees of hue as it gets
colder, so you get an idea of the temperature gradients.

I would like to do a temperature callibration, so if anyone has anything
that will help me do this for the original greyscale satpics, I should be
able to get some kind of a callibration done for the enhanced ones.

I have added some enhanced images from the last couple of days which I will
be adding to (and removing the older ones due to limited space), so if
anyone is interested in these images you can check the links on my webpage
at http://users.ace-net.com.au/~carls/current.htm regularly.

To see how good this set of colours is for viewing very severe cyclones, go
to my webpage at http://users.ace-net.com.au/~carls/current.htm and scroll
down until you see the VERY SEVERE TROPICAL CYCLONES : section where you
will find some links for 6 very intense cyclones and compare the original
greyscale satpics with the enhanced ones, the enhancement is dramatic -
don't bookmark or link to these as they will be set up in a permanent home
on the archive website soon. I would like to gather together a collection
of cyclones captured in the satpics and enhance them for the archive
website, so if anyone has any good greyscale images (coloured coastlines
are OK), please let me know.

Regards,
Carl.

This could have something to do with the Home Page virus that has hit
hundreds of computers around Australia and many more elsewhere around the
planet in the last day or so, as was reported on the ABC radio news
earlier.

It is said to send itself to everyone in your address book if you use
Outlook Express, and has apparently clogged up systems all over the place,
so is probably causing the network to behave like it has had a hefty dose
of valium.

I recieved it a couple of days ago, and didn't think much of it at the
time, as it was just a junk email saying something like "Check out my Home
Page at (some URL)", however it came with a (string of letters).EXE
attachment, so I was a bit suspicious.

I use a Mac so xxx.EXE files are just useless junk that clogs up my HDD and
I trashed it. I would guess that if you open this email in Outlook Express
it launches the .EXE file, reads your address book, and sends itself to
everyone.

Regards,
Carl.

The Dapto event of 18 Feb 1984 was probably the most remarkable.
Wontawilli had 515 and Huntley colliery 467 mm in 6 hours - NSW records
and in 9 hours Wongawilli had 653 mm - an Austrlaian record for that
period --- not even Bellenden Ker has done that good!

Good Morning all..

Nice chilly morning in Bathurst, on weather station, stated a - 1.2 deg at
5.50am .  Car was very frosted over..

I think we are in for a early cold winter..

Andrew,

you are not the only one a little confused by this, as the failure of the
highs to migrate north in winter has occurred in most years since the mid
1990s.

Particularly recently, this has been reflected in the unreliability of
winter rainfall in southern Australia, and the very long lived rainfall
anomalies in the westerly dominated rainfall regions (eg
http://www.bom.gov.au/cgi-bin/climate/rainmaps.cgi?page=map&variable=deciles
&period=36month&area=aus - I suspect the 48 month anomalies are more
impressive, but are not accessible).
This has had a very marked impact on run-off in particular, as demonstrated
the behaviour of Melbourne's catchments
(http://www.melbwater.com.au/system/mainFrameset.asp?path=/your_water/latest
_reports/latest_reports.asp , many regional catchments are much more
dramatic).
The westerlies in particular, have become very poor rain producers, while
much of the rainfall which has fallen (particularly in the SE) has been from
cut-offs, which preferentially favours areas with good southerly exposure
(this is well demonstrated by
http://www.bom.gov.au/cgi-bin/climate/rainmaps.cgi?page=map&variable=deciles
&period=36month&area=vic )

If you look at Melbourne's winter-time pressure (a good proxy for the
placement and strength of the subtropical high pressure belt), only 1996 had
a station winter mean less than 1018 hPa (since 1993), whereas over the
entire 1900s the mean pressure was below this value typically about one year
in two. 1997 with a value of ~1025.5hPa was the highest in the twentieth
century, while 93, 94, 95, 98, and 99 all had values well in excess of 1020
hPa (ie well above "average").

A very good question is whether this is all a chance occurrence, decadal
variability, or long-term climate change, something which quite-frankly we
don't yet know the question too.

Cheers,

David.

Hi Andrew,

At Mt. Crosby, close to single digit figures in the early morning and a
crisp dry wind blowing.  It has extended well up the QLD coast
with a min of 2C recorded inland from Townsville (!!) yesterday
morning (lowest in the state), my max's are briefly into low 20's
at present.

Regards,
John.

Hi David,

Failure of the highs to move North should also result in far fewer
Westerley episodes for Brisbane, meaning above average rainfall
for the winter months due to SE regime.  I wonder if the long term rainfall
patterns for Brisbane also reflect this?  Certainly there seems to have
been fewer genuine Westerleys in recent years, and those occurring much
later in Winter (August - September).

John.

IE can handle Capital letters and blanks in filenames; Netscape can 
handle Capital letters, but not blanks; many other browsers and operating 
systems cannot handle either.  It is important for us to remember when we 
are doing our web-sites that the whole world is not yet Microsoft.

G'day Andrew,

Last winter certainly was a fizzer! I think we (tas)
had about two days where it snowed on the highlands! I
think we had more than that during late spring early
summer!

G'day David and all,

Yes, the lack of northward movement of the highs is a worry. During last
years big snow dump (28th of May), did Melbourne get much rain out of that?
I notice the central pressure of that particular high was around 1034hpa and
it was as far south as Tassie! The low that formed to the east of this high
(south-east of Tassie) was quite strong and helped maintain snow for days up
our way.  This was one episode where snow pelted us for days during a very
southern type high situation. We also had a very good fall of snow in 1999
west of here, (up to 50cm) on June 14, 1999 during a year when the highs
were well south and similar in August 1998, although I don't have the charts
for that one.

I guess I'm trying to get a handle on the situations where snow will still
fall on the Southern and Central Tablelands of NSW under these southward
high type conditions, and May 28, 2000 is an example, I presume. Wish I had
the charts for the August 1998 outbreak. The Bom archives to the public only
go back to 1999, I will head back there now to look at last years outbreaks.

Lindsay,

I also wouldn't forget the July 27th outbreak which from memory also originated from a high stationed possibly even further south than Tassie, which was nice and elongated in the north-south plane. It had a very deep fetch and brought some truly cold air up the NSW coast. The event is forever etched in my mind from sitting up at Robertson and going nuts as the snow buried everything (3-4cm anyway) in around an hour.

I certainly won't complain if we end up with these set-ups again this winter. Bring it on I say.

Cheers
Andrew Godsman

Hi all high pressure "lovers"
Despite the concern that another winter will pass with high pressure control
and a lack of westerlies over the southern states,has anybody noticed the
progressive decline in surface pressure over much of southern Australia over
the past 3 days.
Projected analysis was showing much higher pressure expectations which never
eventuated, instead a decline and weakening of high pressure control has
been underway and it looks as if a phase of cyclonic activity will develop
across the southeast of the continent this weekend.Even now there is a weak
area of upper vorticicty over western Victoria and another appears to be
developing at the head of the Australian Bight.The large area of cold air
south of WA also shows good potential.With the present high pressure ridge
weakening today and slipping southeast an area of low developing over the
bight might then piggyback over the southern high and affect south-eastern
Aus this weekend and early next week.In regards to a tendency for highs to
remain at  a higher latitude than normal over the past few years a clue must
be in part due to the rather warm sea surface temps over the Coral Sea,the
Tasman sea and this year even Bass Strait, which under the relative
conditions at this time of the year become somewhat adverse to the
persistence of high pressure cells and instead be areas of potential
cyclogenisis and this has been the case for the past 5 years or so as Mr
David Jones has pointed out. Bring on the lows!! regards Clyve Herbert.

Worth mentioning here that the ECMWF 24-hour prog for tonight (which
most of you don't have access to) has the 1012 isobar touching parts of
the northern NT and WA coasts, but otherwise, not a single isobar
ANYWHERE over land in Australia!

Note: Clyve Herbert: I just got cut-off from my isp as I was trying to
receive your email on "highs". My mail server played up in a similar way
when receiving Jane's email yesterday. Hmm...

G'day Andrew,

Yeah, I was just looking at that actual chart :) That's the thing, I guess.
Climate change/natural variability or whatever it is, impacts badly on some
and better for others. Most of our (Blackheath) snow last year seemed to be
from setups similar to the one you mentioned in July with deep fetches and
some sort of low in the Tasman. Pity I haven't got a scanner as I have pics
from the July 27, 2000 outbreak demonstrating the fascinating crystalline
structure of that snowfall and also of the snow on our local tennis courts
that took us an hour to remove for our early morning hit-up! Will get more
pics to the local photo/scanner shop this year, if we get some good falls,
no doubt Oberon will as they always get snow.

And Clyve, thanks for your email, it came through the second time and was
worth the read. :)

G'day Clyve,

Even with the possibilty of the current low developing
further - you may notice the westerly 'zone' is still
being pushed further south, thus there are less
frontal systems crossing SE Aus. These frontal systems
are what usually bring "consistant" rainfall to
Tassie, sometimes every 12hrs for days! There is no
doubt that the high's are broken up every now and then
by a low or front, but over the long period, the
pattern has been for more anti-cyclonic conditions to
pervail at higher latitudes over recent years. It will
be interesting to see if this current low develops
further.

Regards,
A.

G'day Lindsay,

Yeh I agree, much of the cold air pools missed Tassie
and affected locations at higher latitudes. I remember
watching the news reports of snowfalls on the mainland
with little happening in Tas.

Hi Dann,

These are great photos!  Love the clarity and definition - a very nice

Hi Michael,

It's been a while since we've had haildrifts in the area like these (in
SE QLD/NE NSW) - I wonder if it's a lack of cold air in the upper levels
(although we have had a few cold pools move through, nothing of this
signifance).  Yet again - I think back to the plethora of reports I have
read in the early 1900's where hail drifts were quite common - perhaps
they were just localised but better documented!  I know I'd love to see
one of those 6ft haildrifts :)

Any idea on how much hail was present the night before?  You would have
expected a fair bit of it to melt overnight and during the day before
you witnessed it.  I guess this makes it even more impressive!

Hi Clyve,

I think that it's interesting that the Melb sounding had a fairly good
SE'ly flow through all levels - although the low levels is not that
strong (10-15kn), I'm sure it would have been stronger out in the
ocean.  The Lorne area steeply ascends into the ranges - I would imagine
that there would have been very significance convergence in the lower
levels.  The sounding suggests it was unstable to around 2500m - but
with some extra forcing, things certainly could have gotten up much
higher towards 4-5000m.

The thought has crossed my mind whether the Lorne area is similar to
Wonthaggi area for SE'lies (where as Wonthaggi does well for
funnels/waterspouts in SW'lies...I think!)

Hi John,

We had Roger Stone lecture in one of our classes - and he briefly
touched on the 11 year cycle in regards to the sub-tropical ridge that
sometimes pushes further north in summer, giving us SE'lies (and he
mentioned as we all know, that the 99-00 season was such an event).  But
he also mentioned that it seems to have been a feature recently (ie, not
just one year) - and we have all observed this, with long lengthy
periods under SE'lies, rather than heat troughs sitting just to the west
of us, gving us humid, NE'ly days with storms on the ranges.  However
the 00-01 season certainly was not cold, and there were lengthy periods
of NE'lies (at times).

But one of the most interesting things he mentioned was that he believes
many of the cycles tend to change in April and May and "lock in" for one
year (espcially anything El Nino or La Nina related).  He said that the
presence of a sub-tropical ridge is normally predated by SE'lies through
winter...which gives higher rainfall/milder winter.  And the old folk
lore does say that a dry/cold winter indicates a good season, and a
wet/mild winter indicates a poor storm season.

I think there are other factors though - obviously a cold winter would
suggest active upper levels with numerous cold pools that would
(hopefully) continue into the summer as the surface warms up (as the
upper atmosphere tends to lag slightly behind the surface patterns).

So all of this is the reason we haven't had a winter of really good, meaty,
squall line and hail filled cold fronts in Adelaide since 1992????

<DIV></DIV>&gt;Hi Anthony, 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Not sure about Melbournites, but I've just witnessed a most amazing 
<DIV></DIV>&gt;transformation here in Wycheproof atm! (11.32 a.m.) In a matter of 
<DIV></DIV>&gt;ten 
<DIV></DIV>&gt;minutes the sky has gone from completely clear and sunny to mildly 
<DIV></DIV>&gt;overcast 
<DIV></DIV>&gt;but only at mid-levels! It has formed overhead and not been advected 
<DIV></DIV>&gt;and is 
<DIV></DIV>&gt;travelling quite noticeably south - north! Surface winds are 
<DIV></DIV>&gt;negligible. 
<DIV></DIV>&gt;Cloud has wavelike formations in it. The cloud deck appears to be 
<DIV></DIV>&gt;continuously forming just south of Wycheproof, moving north, then 
<DIV></DIV>&gt;evaporating again to the north of town. Hard to estimate altitude of 
<DIV></DIV>&gt;deck - 
<DIV></DIV>&gt;perhaps 1000 m? Interesting to me anyway!

I worked in a power station on the shores of Lake Illawarra at the time. I
actually made it to work that day. There had been steady rainfall all night
at Mt Warrigal, but nothing that I had not seen before. By Albion Park near
the Wollongong AWS I was surprised to see flash flooding of several small
creeks.

At Macquarie riverlet I was astounded to find it 4-5 ft over it banks.

We watched at power station as the water started to rise in a cooling water
bays. No one really believed it would get to stage of taking the power
station out, but it did.

At first we simply isolated the electricity to some of the lower pumps like
the mesh screen flush pumps, but after another few hours it was evident that
the massive cooling water pumps would go under. No cooling and your turbines
last 2-3 minutes. So eventually the whole station was knocked out.

 Some laxative must've been pumped into the constipated atmosphere of SE
Australia/ Tasman Sea/ NZ. Systems look as if they're starting to move
again!. We've just our 11th day of cloudy, often drizzly weather, upgrading
to light rain at times this morning. The moisture is great after 3 very dry
months (farmers are stilll complaining that it's not enough - when are they
ever satisfied?), but some proper sunshine would now be welcome.
 BTW, some very summery maximums in western and central areas lately - 23 C
max in Wellington today and last Sunday (6th May); could be a May record.
Some flooding up north though. These warm temps probably won't continue next
week - models now seem to be predicting some southerly changes, possibly a
cold one later in the week. Winter isn't that far away.

Hi all,

Some of you may have come across these already in my what's new page:
http://australiasevereweather.com/photography/photos/new/mb.html

Most are taken from my home at McLeans Ridges or while on local storm 
chases. Some of interest:

The morning of the Brisbane flash floods on 9th March looking NE, number 01 
and 04 are the most interesting:

Some UFOs:

This hit the Gold Coast with severe weather on 26th April:

Some cows came to greet me while on chase:

Anti-crepuscular rays ??? Is that what it's called when clouds on the 
western horizon shadow across the sky to a point in the east ?

Hi Anthony and all,

The storm on 8/1/2001 which tracked northwards along the eastern slopes of 
the Great Divide east of Tenterfield also produced hail drifts, and also in 
SE QLD somewhere??

http://australiasevereweather.com/photography/photos/2001/0108mb02.jpg
http://australiasevereweather.com/photography/photos/2001/0108mb03.jpg

These two pictures were taken about 30km east of where the hail fell. The 
hail was just west of Drake (and 30km NE of Tenterfield) and was described 
in the press as like snow.

In the Wollongbar storm, I don't really know how much more there was, but 
the night and morning was quite cool. There is one photo in my report taken 
by "Maria" at Wollongbar that gives a good idea of the coverage just after 
the cell passed.

regards, Michael

There is definitely potential for many Tasman lows this winter with the warm
water.

As usual placement will be the key and perhaps East Gippsland may be the
place to be.

As for "classic" East Coast lows I am not sure that the situation of highs
being so far south is a good thing, in fact for classic ECL's higher highs
perhaps are better. The ECL label is applied to anything these days and
reality none of the recent activity really qualifies.

You can get these at http://www.ecmwf.int/services/forecast/jmenu/index.html

however only from 3 days out and beyond.

As Blair mentions the 24 hour stuff you can' seem to get.

Your comment about hail has been backed up by reading I have seen.

Particularly for loss of wheat crops due to hail - it seems this was far
more common in the 1900-1950 that the last half of the century.

A couple of interesting images that I collected today while parts of
Victoria basked between the 2 weather systems - the complex low

I wish I could remember the 1979 event, however rainfall records show an
extraordinary event at Cordeaux or Cataract  Dam of over 500mm in 24 hours -
1950's I think.

Hi all,

In replying to this email i'd like to bring up a factor noted by myself and
another 2-year thunder downunder veterans (if you can call us that).  It has
been noticed that inland areas of NSW and QLD have, during the spring,
recieved above average rainfall and possibly as a result, have somehow
increased (or maybe thats just our perception since we are now chasing out
that way) the number of troughs which retract and park themselves in inland
QLD and NSW throughout the spring time.

One of the main factors influencing this has been attributed to, but not
confirmed as being, the ridging up the east coast being situated more inland
rather than sitting more off the coast.  This relates somewhat back to what
JImmy has mentioned when refering to the less then normally active storm
seasons in Sydney over the last 4-6 years.

It would be interesting to look at the the high pressure systems and their
relative positioning over the Australian continent when compared to the
early season rain events in the western areas of NSW and QLD as well as the
storm events over the coastal areas.

Regards,

Andrew McDonald
a.k.a. Macca (not in the best health i could be in writing this email)

Hi again all,

I must remind people that the events of late May 2000 were of a nature not
likely to be repeated in the next 30-40 years.  It was a phenomenal event
and I was in QLD for all of it (just to rub it into myself a little more).
As for relevent snow seasons over the last few years, I would have to say,
given personal experience, that 1997 was the last time we had what used to
be termed an "average" season (although some may consider it above average).
I think 1997 proved to be the last season where many Victorian ski resorts
had over 200cm of settled snow come the middle of August - meaning that
about 250cm had fallen between the start of May and the end of July and by
mid-August there was a good cover of packed snow sitting at over 200cm..

I would be interested if someone could provide the last say 10-15 years of
snow levels at the major Vic resorts just to see how the numbers turn out
and to compare it with what has occurred elsewhere around Australia.

Regards,

Andrew McDonald
(hanging out for some snow)

Hi All.

Experimental satellite lightning image :
http://www.awc-kc.noaa.gov/ltest/WORLD.GIF updated every 30 minutes.

On this (almost) global IR satellite image you can see where lightning has
occurred in the last 3 hours (last hour in red, previous 2 in yellow).

Unfortunately, they think no one lives S of about Adelaide.

Regards,

Michael...
The main reason you can't remember a 1979 event is because there wasn't
one. The wettest day in Wollongong that year was 22 June with 51 mm. No
centre in the Illawarra exceeded 60 mm in 26 hours throughout the
drought year.

Hi Michael et al

I take it you would only use the term ECL to describe one of those intense
'bombs' just off the eastern seaboard?

BTW - if anybody can direct me to a good web description of excactly how
these lows and their variants form I'd be grateful.  Living in an area
where most weather comes from the west, it all seems a bit
mysterious...[well, of course I have a rough idea, but stll....]

TIA

With the latest MSL having 9 lows & 2 highs marked on it (is someone
getting paid $x per low here???), the Bight & southern WA is looking
very, very interesting - strengthening polar jet, cold air being slung
to the NE - we also may see some rather more interesting weather in the
SE of Australia in a couple of days time than the BoM are currently
predicting.

NOTES ON THE WEATHER FOR WESTERN AUSTRALIA
Issued at 4:56am WST on Saturday the 12th of May 2001

SYNOPTIC SITUATION AND FORECAST EXPLANATION:
A cold front is expected to pass over the lower SW on Saturday morning
and move to eastern parts of the SW Land Division and southern
Goldfields later Saturday.  A low associated with the front is predicted
to deepen off the south coast during Saturday. This developing low
pressure system should cause a cold, showery outbreak over the SW Land
Division with the possibility of thunderstorms and hail in southern
districts. Winds are expected to become strong and squally near the
coast. Moderate to heavy falls may occur in the lower SW and western
south coast area.

WESTERN AUSTRALIA:
Southern Interior and Eucla: Isolated showers and thunderstorms.
Lower SW and South coast: Showers becoming widespread with a cold,
strong and squally SW change. Local thunder and hail possible. Chance of
some snow on the Stirling Ranges late in the day.

Interesting Don,

I only mentioned this as someone who used to live there suggested something 
about then. Perhaps it was 1978 during the flood years? I stand corrected 
on this one. This person seemed to be genuine and perhaps got the year wrong.

Sorry guys.

Hi all,

The ideal position for high pressure systems to be situated here in NSW is 
just off the coast in the Tasman and not so much well up north along off 
the Qld Coast. This means that inland would be under the influence of a 
N-NE geostrophic flow from Qld through to Victoria. Now a cold front (a low 
preferably) coming from the SW or W can then provide a prefrontal trough 
situation that persists for as long as the high pressure remains in the 
Tasman. I have looked at Michael's synoptic charts of the past and there 
were many situations that seemed to occur like this. This has not happened 
to often in recent years and I would bold as to say not since late 1980's 
from my memory at least on a persistent basis.

Some people have comments that it is good to have a ridge up the SE Qld 
coast though I tend to disagree as the situation provided above is more 
ideal for severe weather situations. Now some people might say that the 
early November 2000 outbreak was ideal in this regards. I just don't think 
it was quite right and it would have been great had there been a good 
geostrophic flow. The January 1999 outbreak from Victoria to Qld was ideal 
for severe weather and supercells but again I think the geostrophic flow 
was not as ideal otherwise it would have been. Now the tornadic dustwhirls 
in SE Qld near Roma we all know that was stuffed by fine weather and 
ridging along the coast. It would have been a potentially dangerous 
situation had there been a NE geostrophic wind rather than a lighter N-NW wind.

Anyway folks, I am ready soon to go to the ASWA meeting and then the party 
starts. David Croan and I are going to the US for storm chasing purposes as 
people already know. I will be e-mailing Goeff Thurtell about any news if 
anything happens and Daivd Croan will be in contact with Paul Graham I 
understand. They will pass on the message on to this list. As you all would 
expect we are excited but not excited about the bloody fat high pressure 
system on tornado alley at the moment!!! Thanks for the well wishes  and so 
I will see you all when I get back.

Cheers

Jimmy Deguara

That's exactly my description of an East Coast low, an overnight bomb.

I can visualise the scenario, but have trouble explaining . True ECL's tend
to occur 24-48 hours after a vigorous W/SW cold front. The front itself may
be aligned to a much larger low way south of Tasmania. You also need a cool
pool of air. The ECL low develops from a cutoff of the cool pool. It' more
complex than that, I could draw it, but have trouble explaining.

Hi Clyve,

Looking at the radar, it looks rather odd and abrupt (ie, pink and red
going into 'clear air' so to speak).  I think they are fake echos,
nothing is present on the sat pic either.  This tends to occur when
they're doing maitenance on a radar.

I believe the Victorian term for this is "FBS" :)

I would like to extend the same courtesy from all of ASWA Queensland -
all the best Jimmy!  I was telling Clyve a few weeks ago that you'll
have lots of practice on driving in the US already, as we all know how
much you like to drive on the wrong side of the road while chasing :-)

Happy supercell, tornado, hail and cow chasing!!!

AC

PS Clyve - You guys potentially could be making snow Jimmy's down there
next week?

Hi MB,

Yep - the storm on the 8th of Jan produced some hail drifts, but nothing
in the order of one foot 12+hrs after the event.

I got some hail drifts up to an average of 6inches (scraped the bottom
of the car actually!)  The URL was:

http://www.bsch.au.com/storm_chasing/08_01_01ac.shtml For those
interested...

The hail in this was mostly small - the larger events (ie haildrifts to
1-2ft or more) seem to have occurred with much less frequency though. 
The hailstorm on the 6th you experienced was something like what I was
expected in SE QLD too - but the air was too dry unfortunately :-(  If
we had SE'lies it would have been great (and from what you told me about
your winds, if you had a direct SE'ly with a bit more moisture the
results would have potentially been phenomenal!)

helps greatly. Here are some tips that i use.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
<DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>1. If you have some sort of imaging software, scan 
your image in about a third larger than you intend it to be and squash you image 
down using your program, or html. It may take your images a little longer to 
load, but they are much sharper. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>2. Unless you have a top quality scanner (which 
many do) you won't get very good clarity definition in landscape shots. I use a 
'unsharp mask filter' that sharpens my images dramatically.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>3.&nbsp; Some scanners have a 'sweet spot',. Try to 
find that by scanning graph paper and seeing where the best and most clearest 
part is.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>Hope these help.</FONT></DIV>

Michael....
The two great Illawarra deluges in the early years were in 1898 and
1911. some of the rainfalls were incredible and many 24 hour total still
stand as records today.
Some of the falls recorded at those times - for the 24 hours ending 9 am
on the dates given were:
 
14 Feb 1898 - Cordeaux River 574, Dapto 311, Brogers Creek 509, Jamberoo
278, Mt Kembla               260 mmm
but the best was.....
13 Jan 1911 - Brogers Creek 529, Bomaderry 331, Albion Park 278, Berry
306, Cordeaux 369, Helenburg 310, Jamberoo 277, Kembla Heights 443,
Maddens Plains 474, Mt Kembla 464, Mt Pleasant 264, Nowra 321, Nowra Nth
330 mm
The only other 500 mm + falls before 1950 occurred on  15 March 1936
when a place then called Viaduct Creek had 508 mm and on 5 May 1925,
when Mt Pleasant had 511 mm and 5 March 1893 when Towamba had 508 mm.

G'day Andrew and all,

I'm watching with interest re this latest front in the Bight. Lets hope SA
and Tassie get something out of it. I'm getting a number of the locals into
it all now, as they check out my site. :)

Yes, you are right, the late May event of 2000 was a pretty rare experience.
I tend to not include that event when comparing last years surface patterns
with this years, for the very reason you mentioned, it was an extra-ordinary
event. Still, with the warm water in the Tasman we could see the odd decent
low form there and combine with a nice meridional (I like that word) high to
its west and send some nice cold pools our way. Sadly, as its been
suggested, such a setup last year didn't help Tassie get any snow and I for
one am not selfish (well, a bit) so I am happy to share the snow around.
Maybe this current approaching system might give Tassie a sprinkle of snow
and I reckon Andrew Miskelly also deserves a nice sub 536 cold pool sitting
over Taralga with lots of moisture, this winter. :)

I'll probably open a can of worms here. My thoughts have always been that
our world has "cycles". The latest worries have been with regards to global
warming and that we will have heavier rainfalls etc. We have only kept
records for say 150 years. Does the world heat up/cool down every, say, 500
years and we get some not so ordinary figures.
Was there very hot/cold temps 500 years ago?
Was the rainfall high/low 500 years ago?
Maybe I'm just a sceptic. Is that how you spell it? :-))

Thanks Don, I'll file this E Mail away in a safe place.

The two falls you mention are consistent with rain events from the NE, with
moisture feeding into a trough just inland of the Illawarra. Very similar to
August 1998 in fact.

The Cordeaux River is an interesting recording, however some guess work
local knowledge may spread some light on it. At first it would seem the
recording was made at Cordeaux Dam, however that was not even built at that
stage. Cordeaux River would in fact probably be the now Mt Kembla apple
orchard farm. This isolated farm area ( unusual for the sandstone
escarpment ) is located just behind the escarpment, about 5km north of Mount
Kembla. Mount Kembla village is 200m lower and about 5km further SE.

The area is in perfect position for adding upsloped air from the NE to an
already moist situation, again shades of 1998.

My guess is Viaduct Creek is on the train line that goes from Unanderra to
Robertson.

Awfully close to Wongawilli actually. Now there is a thought as to local
topography.

These shots are simply 35mm photos. But i have manually taken a pan of 3-6
photos, scanned them in individually and then digitally joined them in a
digital imaging program called photoshop. There is a alot of little nuances
about the program that allow you to properly join photos, including
adjusting the hue / gamma so the the photos have similar exposure levels.

I have a series of pans from the Nov 3rd 2000 Western Sydney Tornadic
Supercell which will be completed in the next few days.
There are some other pans on SSC from a number of events.


These are some of my favourites:

G'day folk,

Could someone tell me what Braidwood's altitude is and what its
topographical set up is? I've been there only once (2 years ago) but it was
a very brief visit. I'm just curious about the AWS, there.

Thanks.

Yes Tracker certainly looks good, for a while there Static on my HF radio 
was continuous without a break between strikes, but now at 9:10pm local, it 
has dropped dramatically, lets hope this continues tomorrow and the next 
day over us. Looks like the storms really start to get going near sunset 
and continue for a while. If we don't get lightning tomorrow, might be a 
good chance to get some reasonable cloud feature photographs. I will be at 
work during the day tomorrow but hopefully I will be working outside :)

So all you South Aussie out there wipe the dust off your lenses and go 
outside, look forward to seeing some of your pics :)

Also if you get any really good pics of cloud features or whatever please 
consider submitting them to me so I can add them to the new gallery page on 
the SAStorms site which will be up by the end of the week.

regards
Andrew

Lindsay, Braidwood is not as high as some expect, just a little under 700m.
The geography of the area is very interesting. About 20km to the east the
rugged coastal ranges are heavily forested with peaks to 800m. The coastal
mountains are sedimentary rocks, with some metamorphic and igneous
intrusions. However a transition occurs inland from the coast range and
Braidwood itself sits upon a granite plateau not until Bathurst. The coastal
range extracts some mositure and rainfall increases rapidly from Braidwood
to the escarpment edge at Clyde Mountain. South of Braidwood the Moruya and
Deura river valleys cut a long way inland and there is a very steep drop
from Braidwood to Araluen. Close to 500m in fact. West of Braidwood you
actually cross the Shoalhaven River, at this stage it is not even in a deep
gorge, again very similar to say the Macquarie around Bathurst, also sandy
too. Further west again and you encounter a high range with peaks to 1300m,
these would see snow a few times each winter. Whatever moisture the coast
range fails to wring out, these ranges do, hence poor Canberra cops a really
bad double eastern rain shadow. You can actually notice the difference if
you cross this range from Captains Flat to Braidwood, the eastern slope of
the high range ( still west of Braidwood ) has some pockets of cool
temperate rainforest plants, not rainforest itself, just some moist species.
I find it fascinating, the transition occurs in less then a 1 km.

Michael

Hey Lindsay,

Braidwood is 650m.  Mt Gillamatong is to the NW at 907m.  Area of
rolling hills, granite outcrops, beef & Clydesdales & art studios.
Rainfall 719mm pa over 96 rain days (ave 8 per month). Summer max
rainfall, later winter / early spring the driest. Not too far east of
Braidwood you come to the top of the Clyde Mountain Pass to Bateman's
Bay.  SE will push air up Clyde Mountain from the coast where it wil
condense into 'sea cu' and quite often will continue to rise straight up
until it dries out & the cloud evaporates (got some great video fo this
a couple of years ago during spring).  Much of the cloud coming up from
the coast never makes it any further west & doesn't get to Braidwood.
Can't remember the prevailing wind in that area but suspect that it
would be NW.

looks like we might actually get some precipitation in the next few
days.
Can't remember getting this excited over just a few showers!
Adelaide radar (6pm CST) currently shows a few showers over Yorke Pen.
& BOM predicting a few showers tonight, & storms/showers tomorrow
night after a warm May day of 25 degrees.
Would be nice to get an inch from this - agricultural areas really
need it to start sowing.

Ceduna radar (6pm CST) also shows some storms bearing down from the
west as I write.

Tim.

Woke up at about 3:30am this morning and to my delight looked out of the 
window to a huge flash of lightning to the west.  This lightning kept up for 
about an hour, a  flash every 5 mins or so.  No more lightning right now but 
the forecast now calls for RAIN PERIODS in Adelaide today.  Be interesting 
to see if this comes off.  The very very slow moving nature of this system 
could see some heavy falls possible, us Adelaide folk can only hope.  
Gardens are just hanging out for something.  After today it all gets a bit 
messy, a bit hard to say what will really happen but showers are possible.  
Bring it on, only hope we get some very decent rain today but the forecasts 
for this system have changed so much who knows what will happen.

Hi all,

Much to my pleasure i was awoken just before 4:30am Adelaide local time, to 
hear the words "There was a Flash". I jumped out of bed in the usual 
morning superman effort and raced outside. Few minutes went by and nothing, 
tried loading the computer, but the computer decided it was too early to 
come on so that took ages to get it going. Made myself a coffee. Flash! 
walked outside with video camera and coffee and sat out there, about 2 
minutes and 30 seconds later Flash! Got that one on film :) Another Flash 
to the SW was basically the end of it. Radar showed a small cell about to 
hit McLaren Vale (good place to be in winter) associated with a medium 
sized rain band feeding in from the WNW (I think). Oh well it's only the 
start of what might happen today. Will keep you posted, also any other 
reports from SA peoples would be good to hear too.

I am off to get ready for work

:(

regards

Andrew from Storm Central :/ <--hey good name for an all round AU storm 
site :) minus the Andrew bit.

This is from the Area 50 aviation forecast (ie: SE SA) - does anyone
know what RERA means? between the pressure & remarks.  I assume it's
"something" rain, but I haven't come across this one before.

Thanks,

Wollongong,

The coldest start of the year this morning, with the first single digit start to the day. 9.2 deg C at North Wollongong (1km from ocean) sometime before 5:30am, but up to 9.6 with a light NW blowing to raise the temp marginally at 6:00am. Bring on that crisp, no feeling left in the fingers feeling when riding to work.

I would imagine that if other areas remained free of the breeze that we may have seen some good frosts this morning around NSW.

Cheers
Andrew Godsman

Michael,

My thoughts for Viaduct Creek would have been closer to Stanwell Park where there is a viaduct which the present day south coast rail line passes over. But only my guess here.

My guess is Viaduct Creek is on the train line that goes from Unanderra to
Robertson.

Awfully close to Wongawilli actually. Now there is a thought as to local
topography.

Morning Jane,

RERA basically stands for 'REcent RAin'.  Actually, to be more specific,
RERA would be moderate or heavy rain that has occurred since the last
report. REBLSN would be moderate or heavy blowing snow that has occurred
since the last routine report, etc.

Search for RERA on this page
(http://www.msc-smc.ec.gc.ca/nwsd/metar/mtrwkbk_e.cfm) for more info.

Regards,
Mal Ninnes
(Sydney)

Hi Michael and all,

1/ That was excellent Michael, thanks.

2/ We had a very mild night here in Blackheath ~ 5C, still it has been a
cooler than average May, so far. Anyone else seen the temp anomaly maps for
Australia, very interesting in the south east, for May.

3/ Fingers crossed for Adelaide today :)

Hi all

I got just under 2mm in an overnight shower at St Peters.  Now its so warm
it feels like March not May.  What a wacky year we are having.  This month
is going to have to get very cool and wet very quickly if Adelaide isn't
going to end up with a large positive temp anomoly and a massive moisture
deficit.

However - the sky now is full of ragged 'summer style' cumulus.  I smell
rain and thunder.  As we say around here - bring it on!

Any of the WA people on the list know if any snow actually fell? 
The numbers coming out of WA on Saturday afternoon (late afternoon temps 
widely in the 6-10 range) would have suggested a 600-800 metre snowline
(the Stirlings peak at just over 1000), but I've heard no reports one
way or the other.

It warmed up quite a bit overnight, so I'd expect any snow that did 
fall would have been washed away by Sunday morning.

Braidwood does have a bit of exposure to the east - as Michael points
out, the second range (the Black Range) west of Braidwood has a major
rainshadow influence west of there. 

The result of this is that, although Braidwood's mean annual rainfall
isn't too different to Canberra's, it is more susceptible to extreme
high daily rainfalls - there are 20 instances in a 113-year record
of daily totals exceeding 100mm (plus a few other 2- and 3-day 
accumulations), about one every 5-6 years, whereas at Canberra the
return period for such a fall is more like 30-40 years. May 1925 was
particularly remarkable (as it was on the South Coast - a couple of
coastal stations topped 1200mm for the month) - there were four
separate days in the month with more than 100mm - 142.2 on the 11th,
111.3 on the 19th, 199.9 on the 27th and 101.6 on the 28th.
This, not surprisingly, produced major flooding on the Moruya and
Shoalhaven systems, although frankly I'm surprised it wasn't even
more severe, given the rainfall totals.

Hi all.
A bit of an odd shape to the low approaching south-east Aus: note the
Hammerhead concave shape near the centre,I haven't seen this formation too
often,seems to be where the wrap around pushes into one of the convergence
bands ....good stuff!!.regards Clyve Herbert.

On the northern side of the low we have the upslide in the developing
baroclinic leaf. On the southern side a drier and descending airstream in
the westerlies on the southern side of the upper low. The line where the two
meet is a deformation zone. It's actually a pretty common feature and this
one looks like a classic case straight out of a dynamic meteorology
textbook. It's rare to see such a clear example.

Lots of cumulus and high cloud starting to rush in from the north over 
Adelaide at around 3pm.  A line of activity is evident to the west and the 
rainband is still hovering over Eyre Pen.  Rain periods and local t'storms 
are likely tonight with gust to 40knots possible.  This rainband is very 
very slow moving and if it remains slow moving and combines with the cumulus 
developing now, Adelaide could be in for some decent falls overnight.  
However we have not had a decent long lasting rainband here in Adelaide for 
ages so I'm not holding my breath.  The low is expected to deepen quite a 
bit tomorrow and could send winter like, windy, wet and cold weather north 
over the central districts.  Whatever happens looks like we are in for an 
interesting couple of days finally.  The ants are going crazy as well at the 
moment.  The western side of the low also looks rather impressive at the 
moment too.  Bring it on!

Hi SG.
The ants  appear to have disappeared from Leopold washed away by our record
rains of April (173mm), however the frogs have been croaking for the past
two days,its about time Adelaide had something.regards Clyve H.

Hi Mark.
Yes,its not often a meteorological development parallels the text book,as in
this case.I have always been fascinated by deformation zones which as you
know can occur at all levels and at relatively thin levels seemingly
detached from other levels,also can be rather confusing when at times one
would expect a jet on the poleward side only to find very light winds and no
jet!although on animated sat imagery its possible to separate the different
types.regards Clyve Herbert.

Hi all tropos.
There's a bit of activity going on around the Solomon Islands, not very
organised but showing some weak potential,also an interesting convergence
zone to the south of this area and a very nice and large tropical moisture
plume extending across the central pacific and southward towards Antarctica.

Might be thinking of the 10-11 March 1975 event - 591mm in 30 hours 
at a (non-Bureau) gauge at Mt. Keira. (This area has a pretty 
dense network of gauges and pluviographs, run by the Bureau, Sydney
Water, the Public Works Department (or whatever it's turned into) etc.).

As for the 1984 event (which I'm currently writing up for the next
AMOS Bulletin), the main culprit seems to have been a mesoscale low
that formed just north of Wollongong and stayed near-stationary for
several hours. This is reinforced by the fact that in the period 
between 0400 and 1000 on February 18, which was when Wongawilli and
places nearby got their heaviest rain (515mm in 6 hours at Wongawilli),
a gauge at Beth Salem, 25km to the NNE (which got as much rain at
Wongawilli through the rest of the event), was almost completely dry,
suggesting a local offshore flow in that area.

500 was also topped at the then Sydney site (Rose Bay, IIRC) in a 
day in the 1840s (can't remember the exact date - it was mentioned
in Henry Russell's diaries).

Hi all,

Well we had a storm here today - very localised but I received 25mm! Next
door says it was flogging down for 30 mins.

That's almost a daily record for Darwin!

Formed on a seabreeze convergence line directly over the coastal areas of
Darwin.

Hi all

Just looking at the local Adelaide radar shows an abundance of blue/cyan.
However, none of this is within 50km of the radar.  In particular, there
are some reflections to the north, which judging by the motion of all the
other stuff, should pass over the radar, yet disappears at the 50km range
mark. So, I'm gathering that most of the blue stuff is simply virga???
Also, the rainfall totals around Adelaide, which peak at a whopping 0.2mm 
don't suggest much has fallen of late.


Cheers

I am pretty sure its down this end. I will ask my mum, she is in her 70's
and was born on a farm in Wollongong.

I know the viaduct you are referring to but I am sure that creek has a
different name.

The South Head Station twice had + 500 mm in the 1840s.
On 29 April 1841 it had 511 mm and on 16 Oct 1844 it had 518 mm. In
russell's book on "The Climate of NSW" 1877 on page 13/14 (in the Bureau
library in Melbourne if you want a copy) there's a detailed account of
the October 1844 event including periodic breakdowns  given by the
observer - a J. Phacock.... interesting and worth a read. He referred to
"a fearful squall with wind and rain came on with thunder and lightning
at 1.30 pm on 16th. It last to 4 pm during which time 10.61 inches (269
mm of rainm fell." That's what I call a decent fall but being coastal it
is hardly topographic.

Unusual events developing in Adelaide at around 8:00pm or just before, we 
got a rather strong infeed of moisture from the ocean, increasing humidity 
significantly and introducing very fast moving areas of low cloud it has 
settled down a bit now at 8:30pm.  Winds from the southwest were fairly 
strong at times a gust of 50km/hr at Adelaide Airport.  Still a good 
rainband to the west be interesting to see how this reacts with the low 
level moisture, if the rainband ever arrives, it is taking ages hope it 
doesn't slip away all together.  Also I don't know if I've ever seen such 
strong winds from the SW ahead of a front moving east or south east???

The ants  appear to have disappeared from Leopold washed away by our record
rains of April (173mm), however the frogs have been croaking for the past
two days,its about time Adelaide had something.regards Clyve H.

Maybe the frogs have eaten all of the ants and that's why they are croaking
:-)
A big contrast from here as I only picked up 19mm for April, and only 10.2mm
so far this month. As most places in Vic probably are this morning it is
very warm at present sitting on 15 C. Leading up to this morning we've had a
few sub 4C temps overnight.

Yes, there was quite a bit of virga falling from small Cu for much of

Good rains to the west [20mm], but another night of 'all blow and no go'
for Adelaide.  Another mm or two is not enough!  A few woosy rumbles of
thunder at about 10.00pm

I wait with bated for the arrival of the colder air later today....

Well last night was dissapointing here in Adelaide as only a few showers 
developed and dumped a small total of just over 3mm.  Anyway I'm amazed at 
how deep this low is getting, pressure on latest MSL chart down to 993hpa 
and some very tight isobars.  Front to the SW of the low seems to be a 
little bit stronger than may have been antisipated and is now introducing 
cold air to the western side of the low from as far south as 50S or more.  
Glad the low is moving east as well instead of south east, even though it 
will probably gain a slightly south east track again soon.  Could always 
remain eastward moving though or even north eastward if we were really 
lucky.  Hope to get some decent falls out of shower activity this arvo 
onwards, Adelaide really needs it.  However after last night's bad rain 
performance who knows what may happen.

Hi all Adelaide-ites,

I for one am hoping you'll get some great weather through town later today or preferably this evening as a bumpy trip across on a plane will be worth it to arrive to something exciting weather-wise. I have a work trip to Adelaide for Wed, and seeing as this will be my first visit to the "stable weather state", hopefully I'll get a taste of a strong, cold front on arrival. In the meantime let the pre-frontal weather give hope of a good day.

Cheers
Andrew Godsman

PS being work I won't get much chance to site-see, but the camera will be ready.

Hi,

Seems to be quite a bit of speculation as to what the low will do.  GASP
still has it vanishing off to the SE very rapidly to be replaced by a
monster High with a fetch halfway to Antartica that will make conditions in
Brisbane literally frigid by Friday night.  The current BoM chart shows the
Low moving directly East, but the 00UTC chart has the front in Sydney by
10:00am tomorrow with the low slipping down the west side of Tassie.
Curiously the 1200UTC chart (from a different model obviously) has the low
placed west and south of this position 12 hours later...  On the late news
last night the spokesman mentioned the front as moving at a snails pace
across inland QLD and not expected to reach the coast until thursday night
at the earliest..

Votes anyone??

John.

Hi Simon and all,

We already have a live weather chat on the internet, its on IRC on the Austnet
network. Up to 20 people each night usually come on, sometimes even more.
(nearly all of them are also on the list).

For instance right now at 1pm WST (Tuesday), We have 16 people on right now and
its not even Prime Time.

To get on it, you have to download mirc at:

http://www.mirc.com/

Or you can chat via the web at:

http://www.kisser.net.au/kevans/Javachat/

I don't know whether you have tried it but we have set up a weather forum on our site.<BR>
<BR>
http://beta.weatherzone.com.au/cgi-bin/Ultimate.cgi?action=intro<BR>
<BR>
It is not a realtime chat but messages appear the instant they are sent. It's perfect for posting messages that you want people to see ASAP. It's not good for rapid fire back and forth conversation style of messaging - ICQ, IRC or Instant Messager is much better for this.It's free and anyone can login and post messages. It has one significant advantage over a realtime chat in that you don't need to be there all the time to see other peoples posts. So give it a go, it may be what you are looking for. <BR>

</BLOCKQUOTE><BR>
<BLOCKQUOTE>Hi All, <BR>
<BR>
A couple of times I've seen and wanted to post messages telling people of something that is happening &quot;RIGHT NOW&quot; and by the time it processes, the event has passed. <BR>
<BR>
I've grabbed a free (adv.) chat program from the net, and slammed it up for AusWX so that now we have our own REAL TIME chat. <BR>
<BR>
Don't expect people to be on there all the time, but I'm sure if you check in and check out, you will find time when it is quite busy with other people on this list. <BR>
<BR>
SO.... bookmark and go to: www.tastyworm.com/weather/ &lt;http://www.tastyworm.com/weather/&gt; &nbsp;for the realtime chat session. You don't need a password or anything, just jump on and chat. <BR>
<BR>
I'll be on for a while just now to see what people think (if it's a good or crap idea) <BR>
<BR>
Thanks!<BR>
Simon <BR>

Check out the Adelaide local loop at the moment.  Interesting
squall-line-esqe feature approaching the coast.  Lots of red in a 'knot'
about 60km south of Adelaide.  looks rather dynamic.  Anyone care to
comment?  mesoscale features here?

A few showers falling in Adelaide - nothing dramatic yet.

Hi all.
Just checking the sat pic and it appears the low south of Adelaide is
becoming complex with a new centre of vorticity apparent just west southwest
of Mt Gambier,and another centre (old one) further to the southwest.regards

Nothing at all happening here. An isolated flash or two well north of here.
No rain and clear sky to the west. Looked very threatening around 4pm but
fizzed out.

   Hi all, just a quick question for anyone in Sydney, late this arvo 
looking to the west it looked like a sky full of 'box jellyfish', their were 
that many small clouds with what appeared to be virga underneath them, but 
the clouds did not appear to have enough substance to them to be rain 
bearing, so was it something else?.. looked nice all the same, thanx, 
Rune...

Looking at the Adelaide obs, at around 20:30, Mt Lofty had received a gust
of 102km/h, ~88km/h sustained.  Not too shabby!

The Victorian section of the Ozwind site at
http://www.ozwind.com.au/homeindex.php3 now has 4 maps of wind
directions & strengths which are regularly updated - South West Coast,
Port Phillip Bay, Wilsons Promontory & East Gippsland.  Some of the
recording sites update every 10 minutes.  It's worth a look at the SW
coast map for some 25 knot winds around Hamilton.

I recall Sydney had a fall of about 9 inches in 2 hours from a
thunderstorm one night in March several years ago (early 90s/late 80s?)
and there was a comment that Sydney Harbour had actually helped sustain
the storm's intensity (it was apparently already slow moving or else the
storm stuck around because of the moisture supply).The falls were
locally confined to the inner eastern/southern suburbs much like the
April 1999 one and out here at Seven Hills there was scarcely a drop of
rain.

We've also had a couple of shower periods that have contained bursts of 
torrential rain, so heavy you could here it coming even though it was 
already raining steadily, plus at about 4:30am as a very heavy shower passed 
over and some rather small and brief hail developed but was almost instantly 
washed away by the heavy rain burst at the same time.  Anyway the cold air 
mass to the south making its way morthward hopefully we are in for some more 
good falls currently on around 12mm here in Adelaide.  Only problem is these 
shower periods are very brief to bring sustained rain it's very hit and miss 
stuff.  Also interesting to see how the low to the south east develops, if a 
cold front or trough will be pushed NW from the low up towards the southern 
SA coast or is this already happening?

G'Day All,

Interesting little setup (IMO), it has felt a little more like Spring
here, over Autumn, and this next potential storm situation actually does
look a bit like an early Spring one.  It was interesting and encouraging
to see the development late yesterday in northern central NSW and
southern central QLD become lightning active!  Also interesting is the
sat pics and radar for the NE quarter of NSW - it appears that the front
(albeit weak), has separated into a front and PFT (pre-frontal trough). 
There are a line of decaying TS on the PFT, with old strikes present,
and another line of TS behind it on the front with one very lightning
active cell an hour ago on TWC (tracker hasn't updated since).

I think that there'll be storms again (despite the drier air out west)
given the situation.  I'm also wondering if we'll see anything from here
(anvil or lightning wise), later on today/tonight.  Some nice shear is
progged to be associated with this, 50kn  at  500mb, 120kn  at  250mb...temps
around -15C  at  500mb also.  This is not extremely cold, but it is
sufficient given that our temperatures and DP's will be up (mid 20's for
the temperatures, with perhaps some areas out west getting to 27-28 west
of Ipswich tomorrow if it is sunny for most of the day), and DP's
generally sitting around 15-17.  My only concern is that the winds could
shift NW'ly, which would not be any good for us!  The change is S to
SW'ly also, which tradiationally mean everything is touch and go.

I guess we'll see as the situation unfolds!  Actually the current
situation does remind me slightly of October 14 last year, which
resulted in an early morning squall line that produced one confirmed
tornado, with several other possible sightings.

There's actually a fair bit of AC and ACCAS around (although more so to
the east) - certainly a fair chance today even...it just depends on how
much this front slips south as it moves east...

AC

The Vic (Area 30) aviation forecast has the word 'snow' in it!!!!!

Lunchtime had some pretty grunty cjs & cbs about with what felt like
soft hail!!!!  Tops seemed to be getting to around 25000' (guess). If
every day in winter held this sort of promise, I think everyone would
migrate here for the winter!!

G'day all,

The latest Gasp run (wed. night) has a nice cold (cold-ish) pool over the
Central Tablelands for Friday and Saturday. Its nothing frigid, I know, but
its a start and the sat pic looks nice too. Hope there's a bit of moisture
with it.

Reply-To: aussie-weather at world.std.com

Hi all - visitors are more than welcome to attend!!!

Apologies for the late meeting - we were moving the meetings to every
two months in the quieter season, however it was later than anticipated!

The next QLD ASWA Meeting will take place on Saturday, the 26th of May. 
Time will commence at 10am as usual at the usual venue of Spherion
Technology, Level 4, 200 Creek St, Brisbane.  

There's quite a few items that need to be discussed, as well as ASWA car
stickers will be on sale for $4 each, and for those whose membership
falls in May, it would be a prime time to renew their membership!

April and May have been fairly interesting weatherwise, and there'll be
lots of footage from these months to display!  As well as some "Thunder
Downunder 2000" chase footage that I'll bring, so plenty of new stuff to
watch!!!  We'll also look at a recent event in depth (probably the the
May 6th cold pool), and have a look at the mechanisms at work - in
particular for NE NSW.

The details recapped: 

Date: Saturday, 26th of May 
Time: 10am - if you come late, phone 0417 759 304 and we will send some
one down to let you through the security. 
Venue: Spherion Technology, Level 4, 200 Creek St, Brisbane 
(Right next to the Novotel) 
What to bring?  Yourself, storm footage/photos you want to 
share, any visitors, $4 for pizza and drinks. 

If you can come, it'd be great if you could drop a quick email just to
let us know for numbers!

Look forward to seeing you there!

Hi all,

Some more chase reports have been updated:

http://www.bsch.au.com/storm_chasing/27_01_01ac.shtml
Just a short one - but check out the little "rotation spot" I parked
underneath...

http://www.bsch.au.com/storm_chasing/28_01_01ac.shtml
Some nice lightning captures here, was a nice day - except for the
unfortunate experience I had when I hit the floodway in heavy rain...

http://www.bsch.au.com/storm_chasing/18_03_01ac.shtml
Fun chase into Redcliffe - some strong (but not severe) storms, but some
great updrafts on the back ends as they moved out to sea!  Also "The
Bridge" encounter...

For all of my 2001 chase reports see:

Hi All.

If you go to http://users.ace-net.com.au/~carls/current.htm you will find 4
coloured satpics embedded in the page -> Coral Sea, NW WA, Southern
Australia, and the South China Sea.

These are from a recent GMS5 FNMOC full disk image with colour highlighting
ranging from deep blue for the dark areas through cyan to pink for the
bright areas.

I will update them from time to time over the next few days, however I may
set up a proper page for them if I decide to make this a regularly updated
part of my site as it makes my page load a little slowly. Don't bookmark or
link to the images themselves as the URL may change.

Morning all,

A nice little low that appeared west of Tasmania yesterday has moved NW
(probably cheating the models) & is currently sneaking up on Adelaide from
the SE.  (see Adelaide broad radar loop) It's bringing some seriously cold
air at 850hPa up from the south which should destabilise things somewhat!!
The line of showers currently heading towards Melbourne from Bass Strait is
part of this system.  Now if that's not a wild card, I don't know what is!!!

Hi All,

Not looking to shabby in BNE this morning, shallow unstable layer around
3500m still there, and evident with  Accas around in the west, DP's high
teens, last nights cap was just 2.8C and anything breaking that could go to
7400m and maybe 9300m if its strong enough.  Plenty of solar this morning
too, very little wind which should mean NE seabreeze will happen early.

John.

Pretty good.
The TCFA currently in Beibu Wan doesn't look much like a TD yet though.
I reckon this colour treatment would allow you to make truly excellent 
animations from satpics next time a TC develops somewhere.

Hi all,

Interesting to see that Charlotte Pass reported snow at 9AM this
morning. They also reported 25mm of precipitation - I wonder what
proportion of this was also snow! Their minimum was -3 and their maximum
4 so there would have been room for quite a bit.

Andrew.

Hi all

Not sure if anyone has posted this already, but here is a nice weather
page from Germany which plots various weather parameters for Australia
(and other world-wide locations).  
If you want to test your German, check it out here: 

http://www.wetterzentrale.de/topkarten/

Otherwise, have it translated into English via the Babel fish translator
at AltaVista by going to:

http://babelfish.altavista.com/tr

and entering the above URL and selecting 'German to English'.

In the top left frame 'Beobacht.' means observations.  Clicking on any of
these items brings up another menu where you chose which part of the world
you want to see the data. E.g. clicking 'Beobacht.' and then 'World-wide'
allows you to select temp/dew point.... for Oz which comes up in a nice
graphical format.  By all means play around and see for yourself.


Cheers

Found this link this morning, it shows up-to-date wind reports (in graphical

Hi Jane and all,

Don't you just love it? Yeah, what a nice little low it is. How will that
interplay with the current pattern, I wonder? Hope Adelaide gets more out of
it, they deserve it, not just the weather dudes but the farmers too. SG,
Phil, others, keep us informed :) I look forward to the next GASP run etc.

The BOM has sleet possible just to the south of us now, and we are fairly
south in our central tablelands zone, so we still might see some white stuff
on Mount Trickett (1362m) , hope so.

Yeah, nice bit of rain on the Adelaide radar before moving north over
the city around that low (which looks spectacular on the sat-pics.

AVN have a cold pool with 540 thickness developing NE of the low at the
moment and getting stronger (?!) until it dies later tomorrow. It's
forecats to move NW and die over central-west NSW somewhere.

Sheep Graziers warning has been issued for Southern Tablelands and SW
Slopes for tonight and tomorrow.

Andrew.

This to me has been one of the best unexpected weather days here in Adelaide 
for ages.  Most people are shocked at how much rain we've had.  Going out 
today everyone is talking about the rain.  Basically it hasn't stopped since 
7:30am here, and some rain periods have been very heavy at times.  My crappy 
rainfall gauge is now overflowing way over 40mm because I forgot to empty it 
this morning.  Right now it is pouring with not a single gap in the clouds.  
I was starting to seriously think this month would be well below average in 
rainfall terms however we are now approaching 50mm mark and maybe more!  It 
is great for the farmers in areas where rainfall has been recieved.  Weather 
reports last night indicated farmers suggesting the rain we had had was just 
enough to settle the dirt however now it has drenched the dirt in areas like 
Adelaide.  Feels way more like the end of winter with all the water lying 
around everywhere.  I am no longer depressed about Adelaide's weather 
situation as things are starting to look up but this is definatley a freak 
event.  Bring it on!

Hi all!

I was able to chase after uni today, the main point of interest was
coming across a strip of trees that had come down from the storm, with
almost all trees in the area receiving some sort of damage!  I also got
some nice hail drifts, up to a foot in some places!  I've uploaded a few
captures...a chase report will follow in the next few days.

http://www.bsch.au.com/anthony/May%2017/HailFog1.JPG  <-- Some hail fog

The storms were moving incredibly fast today - made it difficult to
chase!  But the cell that did this was certainly a nasty one...whenever
I got close  to it, I got caught up in torrential rain & hail, and then
I wouldn't be able to overtake it due to the road network.  Also a very
nice line of storms moved through this evening, it gave some very close
strikes - including one that struck incredibly close!  I was watching to
the NE, and for half a second I heard a high pitched noise, and then
came the bolt which struck just behind the house diagonally across to
ours!  And it came with a simultaneous high pitched crack!!!  (not even
a boom), it was about 20-30m away, certainly a little unnerving!

Hi Michael,

This was 'The Cell' for which the BoM had a STW out, that started NW of
Ipswich around 3:00pm and tracked SSE through Beaudesert on a line that
eventually saw it cross the coast near Mooball around 5:40pm, and was
continuously Red for most of the route on local radar.  Suddenly died to a
green on the border, but then picked up pink again a short while later.  I
had thought it was the Range that killed it, but on reflection think it was
more to do with crossing the 100km radial distance on radar and having the
reflectivity intensities adjusted by the software.

All of the other activity was very pulsy, but this cell stands apart in
being both more severe and very long lasting at 4+ hours and around 200km
path, gives a mean speed of 50km/hr or thereabouts.  (Havn't tracked it this
evening, but that might still be it way out to sea off Coff's Harbour  at 
11:pm!! and still pink)

Regards,
John.

Hi everyone

There is a chance of storms today in NSW, southerly change will  move up
the coast and *extremely* cold upper levels  (-26C at 500 in the
Tamworth-North west slopes and plains area) with the weakening upper low
should hopefully provide enough instability to kick some storms up.
keep an eye out it should be very interesting., I will be in Newcastle
for the next 2 nights.

BTW anthony awesome hail drifts!!! severe storms in SE QLD in May...
pretty rare !

Hi John,

Just in regards to your comment on radar reflectivity - do you know if the
bureau's radar software does actually make compenstations like that, based
on singular preset ranges (like the 100km example that you mentioned), or if
the display software automatically makes continuous discrete adjustments
(sampled at small intervals over a larger range)?

Regards,
Malcolm

Hi all

Yes, agree with all of that SG.  A very suprising day and a reminder that
sudden small scale cyclogenisis can happen when you least expect it and
catch even the experts off guard.  I got 42mm, but at work up at Magill
near the ranges it felt like more.  It did not stop between about 8am and
10pm!  It was also very cold.

Can anyone offer a dynamical explanation for what hapenned?  How good
[bad?] are the models for picking up things like this?

Interesting to see this feature now drifting NE over western NSW.

However, we should remember that this was a narrow band of rain, and that
fermers on the Yorke Peninsula, in the north, and in parts of the Murray
mallee got far less and in some cases are still waiting for that break in
season.

Hi John,

Looking at all the radar loops, the cell the QLD BoM warned for did track 
over the border and crossed the Tweed Coast north of Byron Bay. At about 
the same time it crossed the coast (5.30pm) it rapidly weakened while a new 
cell gathered strength 30ks west of it. This one continued on a SE track 
passing near Byron Bay then out to sea. This storm was very lightning 
active, particularly 6.40 to 7.00pm to my east.

More cells developed further inland with one passing just west of me at 
8.30pm. An area of red passed over the eastern suburbs of Lismore by the 
look, about 5km W of McLeans Ridges. We got some brief heavy rain and fresh 
NW winds as the eastern edge passed over. Lightning was quite frequent but 
mostly in-cloud.

regards, Michael

Hi list! Jimmy emailed me and this is part of his

Hi there Mario

We have had a high here and now the S winds have come
in and the stratocumulus have breezed inland finally.
We are expected a little action over the next few days
so we shall see what happens.

I am enjoying it here and we have just hired the car
and I have driven thankfully (tell Alex) on the wrong
side of the road. Shit do they have a lot of lanes
here and I can't see above the steering wheel.

Hi Malcom,

While you wait for an official bom response, my experience at looking at the radar tells me that there is adjustments made I think at both the 50km and 100km range. There has been ample times that areas of rain have either appeared/disappeared or had intensity changes at these points. So my best guess says that it isn't continuous.

Cheers
Andrew Godsman

There was an interesting interview this early this morning on ABC Radio 
National (no transcript available unfortunately) about with Martin Lisius 
who runs a commercial storm chasing tours business in the US. The tours only 
operate in May and June.

Unfortunately the Australian interviewer was not that well briefed, so 
Martin Lisius had to deftly manage to simultaneously describe the tours in  
compelling detail whilst, at the same time, downplaying the Twister image 
and questions about "driving through tornadoes".

Much to the (unfortunate)surprise of the Australian interviewer, he  also 
indicated that Australia was likely in second place when it came to 
super-cell frequency. The interview highlights once again the high degree of 
ignorance held by the media when it comes to severe weather.

The site for Tempest tours is:

http://www.tempesttours.com

Perhaps there is an interesting entrepreneurial opportunity for someone on 
the list??

They still have one or two spots left for some coming tours - Jimmy??

Hi Malcolm/Andrew,

Yes agreed.  My obs was based on the fact that a large area of blue had a
discontinuity corresponding to the 100km circle line, which I guessed was
extrememly unlikely to be a chance occurrence.  Don't know where the
adjustment is made, I assume at the source.

Regards,
John.

After the torrential rain of the last few days, I notice that Canberra 
Airport's rain for the month has rocketed up to 0.6 of a millimeter.

On present indications it will be a struggle to get to 1mm by the end of the 
month. Not a record breaking performance - 0 is the lowest but certainly 
very likely to be in the lowest decile.

Farmers in Sthn NSW/Nthn Vic must be getting very nervous at the total 
absence of NW cloud bands or substantial fronts so far this autumn. Instead 
we have seen a large number of slow moving highs settle over SE Aust with an 
occasional upper cold pool that has chipped away at the coastal edges but 
left the inland very dry.

Found a cool link for 'Australian Aviation Meteorology' (most of you will

Some interesting (and detailed) reading on many different topics (I've only

Hi all

Check out the following water vapour sat loops which show the development
of barotropic instabilities on the front in the Bight and in the Tasman

For western section of OZ:
http://cimss.ssec.wisc.edu/tropic/real-time/shemi/movies/gmsswwv/gmsswwvjava.html
Look just to the west of Perth, and another nearly due south of the SA/WA
border

For eastern section of OZ:
http://cimss.ssec.wisc.edu/tropic/real-time/shemi/movies/gmssewv/gmssewvjava.html
Look in the Tasman sea between OZ and NZ.


Cheers

Talking of COLD temperatures.....Cobarat 1pm today had a temperature of 9C.
I'd be interested to know what their lowest record max is.  With that cold
pool above them (-28C at 500mb) i'm sure there are a few chilly people out
there today.

Regards,

Andrew McDonld

Apparently some stations south of Adelaide may well have recorded record

Hi all

Firstly congratulations Anthony on your great chase on Thursday!!!  I was
stuck in a TAFE classroom, then a 30 min train ride for much of it.  I did
get home in time for some brief small hail and heavy rain.  The lightning
was great too!!!

Friday night was pretty good too!  You don't really expect storm activity on
a dry SW'er day, but with night falling, up went the storms!  Quite a lot of
activity developed over the inland towards Gatton, Ipswich, Boonah etc.  Two
of the storms showed maximum intensity on radar indicating certain hail.
There were also storms off the SE Qld and NE NSW coasts, several of these
reaching high intensities on radar as well.

The activity in the Ipswich area weakened a little and moved over
Brisbane/Logan after 10pm but still with pretty good lightning and brief
heavy rain.  As I type, it's now just a rain area.

Should I talk about the BoM forecasts throughout all of this???? I don't
think so - it just makes me mad!

Oh yeah...more of this action likely during the weekend.  As Ben Quinn first
said, and many others have repeated........... BRING IT ON!!! hehe

G'day Dave and all,

Unlikely to see snow out of this one, 1000 - 500mb thickness and the  850's
are a bit warm. Although it would be interesting out at Mount Trickett this
morning as it was 3.5 degrees at my place and raining at 6am. Could've been
1C out that way with sleet.

Hi Phil, SG and others,
                      I have a perfect explanation for the rain yesterday in
Adelaide.....non scientific mind you. I left the State yesterday morning for
a 3 day ( fully paid! ) medical conference on the Gold Coast. The minute I
left Adelaide it started pouring and obviously continued for some time. This
is about the 3rd or 4th time this has happened when I have left Adelaide in
the last 3-4 years so next time it is desperately dry I'll leave the State.
Up here at the Gold Coast, balmy and warm and humid. Nice brief thunderstorm
last night ( fist lightning and thunder for me for over 12 months!

Martin Davey

Well the high pressure system near SA is really starting to take up 
residence and looks like it will last for quite a while.  However later on 
in the coming week it looks like this system may disintergrate or weaken 
dramatically and set up shop for some fronts to head SE Australia's way.  It 
is a long way out yet but after this high pressure leaves us it could be the 
last very strong and slow moving one for a while.  It's about time as winter 
is just around the corner and I think most of us are getting sick of the 
strong Autum highs?  BOM's recent climate forecast isn't saying above 
average rainfall is likely through the Adelaide region but at least it's not 
as a severe a forecast as last month eg around a 40% chance instead of 30% 
or whatever it was.  Now that Adelaide's had a taste of heavy rain I'm 
greedy for more.  By the way did anyone see the report on BOM in Adelaide 
during Stateline last night at 7:30pm?  I'm not one for ABC shows but I just 
flicked over as it started, they made reference to the Snowtown supercell of 
1999.  For once it wasn't a bagging of BOM which is good because although I 
like to get annoyed with BOM at times their forecasting has been fairly good 
in SA for this year.  In the report they also made reference to the rapid 
changes in weather technology that have been developing over the last ten 
years or so. There wasn't much info in it that most of us wouldn't know but 
good for the general public.

G'day SG,

Yeah, it'd be nice if the highs start to weaken and head north for a change.
Some of the models are showing a more "normal" winter setup emerging later
in the week with a zonal pattern (at sea-level, anyway) and lows pushing
through. Hopefully this cooler air over Oz of late will help the highs move
a little northward. For us, its okay as we can get snow from meridional
highs and lows in the Tasman but I'd rather see the more traditional pattern
develop, as this sees rain for Adelaide. A good thing.

Cheers,

I have thought about this myself, but the ball game is so different to the
USA. I would be a bit worried to bill it as purely storm chasing. How I
would do it is advertise the things that you can't see in the USA on down
days.

I would advertise Australian storm chasing for lightning, hail and winds. I
would not dare mention trying to score a tornado. On down days we would tour
world heritage rainforests, surf clean beaches or tour an outback station.

It's something I would really like to do, who knows with a government job
like mine you never know when the redundancy package is coming.

At least they are starting to get some action after a week of barely any

Okay, it is official.

Yesterday morning around 9am radar showed light blue passing over Warwick.
At this time it hailed down the main street of Warwick, covering the ground
completely in places. This has been reported by several people i know now.
From what i can gather an area of 2km long x several hundred metres wide
recieved nice hail.

Today, about 13C top and rained most of the day so far.

Intersint weather i must say.

Adam

Want snow?. Then head to the bottom of the South Island this week. A strong,
disturbed southwesterly flow seems likely to persist for the whole week,
with progressively colder air behind each front. Snow is forecast to 400
metres in the south tomorrow, but the level looks likely to drop even
further after that. I can't say how this flow will affect Christchurch and
Canterbury. Slight changes in wind direction are very critical in these
situation as to whether we get fine, cool weather or wintry showers. Looks
like an interesting week ahead, far more interesting than drizzly
northeasters of late!.
 Speaking of cold snaps, during that icy blast in southwest WA last
Saturday, I noticed some very low late afternoon temps on the reports - 3-4
C at a few places. I looked at my atlas of Australia, and one of these
places was northeast of Albany (snow on the Stirlings I guess), but the
other was on the outskirts of Perth! (Kalamunda I think that place was)

Hi all.
Check the huge trough and cloud band extending from northwest WA southward
to Antarctica you  could run a competition for find the lows!, how many can
you find along this cloud band I can see at least 4 and possibly 5 with an
unusual centre of vorticity inland northeast of Albany,also the tropical low
north of New Caledonia looks ok for this time of year,northeast NSW looks
good too. regards Clyve H.

Hi Matt

Ive been watching this site for a few months and have been in contact with the
guys on there chasing expedition in thestates, they are loving it over there,
and even though they are not getting tornadoes, they chase purely for the
reasons you should chase, unlike a few "tornado" chasers over there, they have
seen storms almost every day since they arrived  (sounds like TDU last year...
storms every day ;)

Hello Jane

It is the same here. Light westerly winds drizzle on and off day and night.
Everything outside is getting very wet the moisture is moving sideways soaking
into everything. The moss, mould and lichen are in heaven. I am quietly hoping
for a cold front, to produce some wind so we can open up the house and air it
out, but Im not confident one will influence us soon.

Hi all warm water lovers.
Although a bit late in the season,two areas of interest still exist in the
near Australia region.Its interesting to watch the tropical disturbance
north of New Caledonia although weak can be traced back to a persistent
convective area near the Solomon's last weak.This disturbance is showing
weak upper divergence and there is a concentration of surface convergence
producing occasional larger cumulonimbus clusters on its northern flank
there is also  a weak line of CB's extending northward,it would be
interesting to see what sought of surface conditions will accompany this
system if and when it crosses the northern part of New Caledonia over the
next 12 hours. The other area of interest is  in the vicinity of the Samoan
region northeast of Fiji there has been a persistent and positive area of
convection in that region and is now showing weak to moderate upper
divergence its worth watching this area over the next 12 to 36 hours.
regards (going to have a warm bath) Clyve Herbert.

You will find colour highlighted images of these two disturbances at
http://users.ace-net.com.au/~carls/currenttropical.htm along with the area
JTWC has a TCFA for in the Phillipine Sea.

I have placed T°C bars alongside these images, and alongside the full disk
and the regional ones at
http://users.ace-net.com.au/~carls/currentsatpics.htm - I calibrated the
temp. scale using two versions of a satpic of a cyclone, one of which had
been enhanced for Dvorak analysis for which I also had the temperature
information. I do not know if these IR temps are universally applicable to
geostationary satpics, however if not, they at least give a guide.

I am managing to update all these images twice daily at the moment.

Regards,
Carl.

<P><BR><BR></P>Hi Matt and all;</DIV>
<DIV>&nbsp;</DIV>
<DIV>Yesterday (Saturday) was a great chase day. No tornadoes, although the two storms we were on each had a tornado warning out and the sirnes were squeeling through two towns. We met up with a chaser who had seen three tornadoes from one of the two storms - dont know where as were in great position. Anyway they were both HP supercells - rotation&nbsp;of the entire cloud base was clear as day. Anyway today is a moderate risk and we are in Norman, Oklahoma - looks like we will drop a little south and east. Since it is a moderate risk day a bust is probably on the cards.&nbsp; See you later.</DIV>

<DIV></DIV>&gt;Some rather large storms in the US this evening, few tornado/large hail 
<DIV></DIV>&gt;warnings out. 
<DIV></DIV>&gt;At least they are starting to get some action after a week of barely any 
<DIV></DIV>&gt;storms on the plains.

<DIV></DIV>&gt;Hi all. 
<DIV></DIV>&gt;Check the huge trough and cloud band extending from northwest WA southward 
<DIV></DIV>&gt;to Antarctica you could run a competition for find the lows!, how many can 
<DIV></DIV>&gt;you find along this cloud band I can see at least 4 and possibly 5 with an

Hi all,

The upper cold pool which started in W VIC and SA some days ago has been 
making its presence felt up here in NE NSW. Combined with a developing 
surface trough and fresh S winds from the high, some impressive falls have 
occurred but mainly on the coastal parts.

At McLeans Ridges I recorded 60mm from noon to 8pm yesterday, 50mm on which 
fell after 3pm. After 8pm the rain virtually ceased, with only a further 
4mm to 9am today. There's been another 10 since then.

However, on the coastal strip south from Byron Bay, falls have been a lot 
higher. Some unofficial reports came in over ABC radio this morning in the 
150 to 200 mark. Note the huge difference between Ballina on 251 and 
Ballina Airport on 133. The rain tapered off dramatically NW of Ballina, 
and the airport is a few km NW of the Ballina rainfall site, so it should 
be a correct figure, but a little suspect. My parents in central Ballina 
recorded 145mm in the 24 hours to 9am.

Some imbedded storms have been observed, but mostly offshore. Winds have 
swung from S to SE during the past three hours. Radar suggests the rain is 
patchy or just showers, but the change of direction should allows further 
rain to move inland later on today.

Carl et al

I can't get excited about these current tropical disturbances (even the one
in the Philippine Sea). I think it is too late now in the season, despite
warm sea surface temps in patches.

For TC watchers worldwide, the next best bet is probably south of Mexico in
the next few days.

Simon

Hi all

I know this has popped up a couple of times on the list already, but it
seems I must have deleted those emails....doh!

I was wondering what weather instruments (ie to measure temp/dew point)
people have in their cars and how they are set up (ie where to position
the sensors so as not to be affected by the engine)? 

I seem to remember that someone had posted up a URL showing how they set
their system up (Anthony C?) Any info/advice would be very much
appreciated.

Robert,

I have an inside / outside temperature sensor that sits on the dash in
front of the speedo with the sensor superglued up under the front bumper
as far to the front as I could get it.  I do find that it takes a little
longer for the temperature to stabilise after moving off that some of
the other setups eg: Anthony's.

I have a compass in front of the speedo also - the same model as
Anthony's - which is available from the Australian Geographic shops for
$99 (I think) - I have tried 3 different styles & this is the only one
that I've had any success with, because as well as having an ignition
system that plays havoc with radio reception ( a lot of you are familiar
with the ear splitting whine of my radio .... and that's not even during
electrically active storms <g>), I spend a lot of my time under tram
lines which tends to recalibrate compasses within about 3 days - this
model can be recalibrated within the time it takes to do a U-turn - the
others either pointed N whichever way the car was pointing or had to be
painfully recalibrated manually.

I carry a Kestrel & can be seen scaring the tripe out of other motorists
by having it out the window at various times taking DPs as I drive
along.

I've also found two automatic weather staions in Victoria (1 near
Ballarat & I in Bright) that will give you a report if you ring the
number.  There's another at Flowerdale which currently is out of action
and a few in the high country that can be triggered, and will report
over CB radios......oh, and Robert, if you're thinking about
TDU2K01....buy a CB or else <g>!!! - a Uniden 510XL will do the job
brilliantly for you........

and for those thinking of a video mounting system for the car, check out

Does anyone know whether there is a system available like Airservices
used to run????? They've taken that off the public phone number & are
making pilots buy Phoneaway cards .... it used to be brilliant being
able to drive along listing to the aviation forecast for the area - made
chasing a lot easier because it helped pinpoint the position of troughs
& fronts while you were staring at them

Definitely enough rambling from me....

Hi,

Up here in Colorado our chase season is just starting but not too much
action yet. However, last week we went upto Torrington (eastern Wyomming,
near Nebraska border) and got onto a very pretty supercell. Unfortunatly i
don't have a web server on my machine as yet so photo's would have to be
posted to the list, which i know no one likes. But jus to summerise;

At one stage we counted 16 beaver tails (inflow clouds). The storm had a
persistant wall cloud and at one stage what may have been a lowering but
probably just scud. Rotation was amazing with a flanking upfraught
'wrapping' around the core of the storm, never seen a tower do that before -
photo came out great too! Ended up in central nebraska, had a killer chinese
dinner in some little place and got back to Fort Fun 1am'ish - total
distance 800 miles.

Cheers, Lyle

Hey guys,

did you get onto those 3 supercells in the texas panhandle on saturday?
Looked awsome on the vis, 3 isolated supercells just standing up against the
sheer. Can't wait to see one of them again!

storms we were on each had a tornado warning out and the sirnes were
squeeling through two towns. We met up with a chaser who had seen three
tornadoes from one of the two storms - dont know where as were in great
position. Anyway they were both HP supercells - rotation of the entire cloud
base was clear as day. Anyway today is a moderate risk and we are in Norman,
Oklahoma - looks like we will drop a little south and east. Since it is a
moderate risk day a bust is probably on the cards.  See you later.

Hi,

I would like to correct a comment i made in my post about the storm we
chased on may 10. I said there were 16 'beaver tails (inflow clouds)' but
what i should be clear about is that there were 16 inflow clouds and
probbaly a beaver tail in the distance.

I guess the definition of Beaver tail is just one of those words to indicate
a feature of a storm rather than some scientific definition, hence people's
opinion on what it is differs. The concensus here (to *very* much
abbreviate) is that it is an inflow cloud that forms along the interaction
of the FFD and low-level warm front. The subsidance of the FFD caps the
inflow producing a long laminar cloud as opposed to a standard inflow cloud
that may convect along it's path into the meso-cyclone.

Anyway, this is probbaly only of interest to a few of you who already know
this ;)

cya, Lyle

Hi all,

As you may have all wondered did we get onto the storms Sunday our time? You 
bet - spot on!!! These have to be the most incredible explosive storms I 
have seen - developing into supercells rapidly.

After checking the models at the Uni of Oklahoma Library, we went outside 
and saw the stratocu had cleared completely and cb's were developing 
rapidly. By the time we were heading down the freeway, the storms were 
exploding rapidly with massive updraughts - one dominating. We headed for 
that storm once finding a road east. Although the mean level wind shear was 
approx NE, any right mover (and this one began to right move quickly), it 
would generally head east. We were not able to get onto it except from 
behind on one road so we went back down and around. We met with David Gold 
of the Silver Lining Tours ie the chasers were already out. He never thought 
much was going to happen (except for this particular storm) but we headed 
for this one. We had to chase from the west due to lack of road options ie 
river minimised the road options. The roads in eastern Oklahoma were to say 
the least - CRAP!!! We never were able to get into the right position so we 
entered from the Bear's Cage. Don't worry guys we knew what we were doing. 
As long as trees didn't fall on us due to rapid changes in wind strength, we 
kept going. And so did the convoy behind us... It was like a funeral 
procession!!! In Australia, we have no idea about what it means to have pit 
street chaser convergence. Since this was the first major cell of the day, 
there were TV crews including helicopters, the tours, and of course the copy 
cat chasers... I ended up letting some of the crew take over - we simply 
didn't want to be the ones leading.

Eventually, as we headed east we got into some recent large hail and then - 
wow. Tree damage. There were already tornado warnings for this storm but we 
did not expect to run into tornado damage. It was a mess with trees felled 
and yes power poles leaned over clearly indicating cyclonic (anticlockwise 
rotation) indicative of tornado. It was about 100 metres at least wide of 
intense damage and then less damage further beyond. I would estimate about 
F1 damage (minimum to be conservative). We headed further east with police 
out in force, spotters, and of course chasers making decisions.

Then after stopping further down the road with rain wrapping winds, we 
proceeded and wow. A tornadic funnel spun up very quickly with tight 
rotation. We only got 5 seconds on video before trees got in the way and 
never revealed them again. I suppose we don't know the areas and what lay 
ahead in terms of opportunities.

After letting this storm go, some of the crews who had proceeded further 
reported seeing a major tornado!!! At least the tourists thought that.

We headed west and then SW to get onto another storm further south with hook 
echo. In the meanwhile, the radio was tuned into the TV channel with Garry 
England giving a constant update and reports of the outbreak unfolding. 
Incredible!!

As we headed SSW, we saw what we thought and I think was confirmed by some 
experienced chasers as an LP supercell. Then we saw the monster!! It was 
massive with classic backshear and flanking line including boiling 
updrughts. All storms produced incredible lightning.

As we headed SSW we noted that there was a separate supercell attached at 
the backend which dumped isolated large hailstone onto us. No dents but I 
think US cars have stronger bodies as these were definitely golf ball 
thumps.

Anyway, a great day over all and some good footage and a few photos. You all 
shall see when we get back and hopefull there will be more to come.

Will catch you all.

Regards from the two mad and excited chasers.

Jimmy Deguara / David Croan

Hi all,

I like the new graphics and the front page!  They certainly are great
improvements, especially the direct links to the states on the homepage.

But there is one thing I don't like, and that is the re-organising of
the menus for the states, I think they look tacky.  I prefer the old
format when it was all listed together - rather than spread out.  I
noticed Vic had their forecast page change and I thought "Geez, I'm glad
ours hasn't changed like that!"  But now it's all like that :/  Personal
opinion though - other then that I thought it was great!

Hi Rob,

On Sunday I cleared out files on my computer for some space (30gb
doesn't go very far nowadays...) and I was contemplating whether to
delete some stuff I had kept on my car in regards to setting up a thermo
etc, and I thought "Nah, no one has needed it since, so I'll delete
it."  Of course, some one to askk this question within 24hrs was
inevitable :)

I basically have the same things as Jane does in her car.  I use a
thermometer, it sits on my steering wheel ledge, beside just under the
dashboard.  I found this convenient as whenever I checked the thermo, I
could check the speedo!  (Or is it whenever I checked the speedo, I
could check the thermo...)  I then had the external sensor go out
through the door, and then fed it through underneath my bonnet (so about
an inch of the thermo wire shows on the outside, but I never notice
it).  I then dropped the thermo sensor behind my right light, and
superglued it under the bottom of my car.  I let a little bit of it
dangle (2 inches or so) so that it gets the air temperature, and that
any heat from the car doesn't readily transfer to the sensor (and if you
are driving, the air coming in is unaffected whatsoever).

One suggestion - you can get thermos that actually have a little light
in them - this is useful for night!  I got a velcro strip and put it on
a plastic ruler to provide a base above the steering wheel base.  I then
superguled another ruler on top of the base, so I could position the
thermometer directly to the angle I would normally look down with my
eyes (this is essential for the night light to work on this thermo,
otherwise at the wrong angle you can't see the digits).  I then
superglued the thermo onto this second ruler...and it works great for
me!  

You can get a special car thermo from Tandy's for $33.95 - but the
sensor comes with no adhesive, you have to glue it to something.  

I also use a digital compass - Jane mentioned it, $99 from Australian
Geographic.  It sounds expensive, but it is BRILLIANT!  It adjusts
itself to the magnetism of your car, and is spot on!  You can get exact
bearings of storms from your position, there's no "I think it's sortof
NW'ish" - this thing gives you the direction to within 5 degrees, and
also gives you the direction (W, NW, N etc).  It sits on top of my dash
board.  It means each time you get out of the car, you don't have to
keep looking at a compass either, you can get the bearing off the car,
and then use the car as that bearing and work out the other directions
from there while you're outside filming that tornado :)

Hope this helps...

The coming weekend is starting to look very interesting for SA including 
Adelaide it looks like we will get another stab at getting some rain for a 
low pressure system.  This low however looks like it will be a lot stronger 
with some very cold air moving in behind it with a sufficiently large cold 
pool.  Of course it will be hard to get another upper low move in behind it 
like last time.  Anyway looking forward to see what happens as the weekend 
arrives.

Hi all,

The latest GASP run has a sub 540 cold pool over the south east (including
the Cent. Tablelands) and  -2C 850 temps by Tuesday next week and NOGAPS has
a similar thickness set-up for around the same time. I'm not sure when AVN's
latest comes out so it will be interesting to see it and MRF too. It's
looking interesting for some nice cold air, anyway.

I'm no expert on the models, so feel free to pick me up on anything.

Cheers,

Hi all world wide TC watchers

Guess what, just when I thought south of Mexico was the place to observe, up
pops a TC west of the Indian coast. Looks like it could be a potential nasty
beast !!!!

I can't get excited about these current tropical disturbances (even the one
in the Philippine Sea). I think it is too late now in the season, despite
warm sea surface temps in patches.

For TC watchers worldwide, the next best bet is probably south of Mexico in
the next few days.

You will find colour highlighted images of these two disturbances at
http://users.ace-net.com.au/~carls/currenttropical.htm along with the area
JTWC has a TCFA for in the Phillipine Sea.

I have placed T°C bars alongside these images, and alongside the full disk
and the regional ones at
http://users.ace-net.com.au/~carls/currentsatpics.htm - I calibrated the
temp. scale using two versions of a satpic of a cyclone, one of which had
been enhanced for Dvorak analysis for which I also had the temperature
information. I do not know if these IR temps are universally applicable to
geostationary satpics, however if not, they at least give a guide.

I am managing to update all these images twice daily at the moment.

Regards,
Carl.

I've never really chased a storm, normally I just watch them blow in from the

got in touch with Jimmy for information on the storm but he could not recall the 
storm (he was probably chasing), but he wanted to hear my account of it. I got 
some time to type it up and sent it to him only realising he had flown of the US 
(lucky devil). Michael Bath got the report and it is now up at <A

(thanx Michael). There is no pictures because I didn't think of it at the time 
because the storm was just so menacing. Plus like I said before I've never 
chased a storm and thus, I don't have the equipment...</FONT></DIV>

One MAJOR addition is graphic rainfall/flood information for all states
similar to what has been available for Qld for some time. Go to
http://www.bom.gov.au/hydro/flood/index.shtml and click on each state. The
maps show graphically rainfall for the 24 hrs to 9am, the period since 9am,
and the latest hour, updated hourly. For NSW, NT and WA, you can get
regional maps (follow links at the bottom), and the one for the Sydney basin
is excellent, with an ability to get hourly graphics for the past 6 hours.
There's a similar display for Adelaide Metro area. I presume all states and
capitals will eventually be the same.

One excellent feature, buried rather deep in the menus, is a set of rainfall
tabulations showing hourly registrations for the past 8 hours, 3-hourly
registrations for the past 24 hours, and 24 hour to 9am registrations for
the past 7 days + the since 9am total for today.  They are arranged by river
basin. These are only available for NSW and Qld at present, from what I can
see, and are accessed from links at the bottom of the regional maps. The Qld
section is still well ahead of the rest, with an array of links and a
variety of presentations that should make sleep close to impossible during
major flood times. The links to river basin maps and detailed hydrological
information are brilliant, and I hope will be a model for other states.

Naturally, you can also get flood information on each of the maps, though
this is limited to graphics showing below minor, minor, moderate and major
flooding. Tasmania has a link to a useful page showing the critical levels
(alert, minor, mod, major) for main flood level stations.

Morning all,

Sometimes things drive you vaguely nuts because they don't quite fall
into place when you are trying to make sense of them .....and then you
discover that you weren't far off in the first place!!  What am I
rambling on about?  Yesterday I noticed 'something' - not sure what it
all meant at the time but it was a combination of things...cloud
movement at different levels, a patch of low level (?) cloud in NW
Victoria which stayed put as middle level cloud moved across it from the
west, a possible weak trough that passed through central Victoria during
the afternoon, an enlarging area of cloud between Cape Otway, NW
Tasmania & Wilson's Prom, and slightly lower pressures in central
Victoria - this was all still all apparent last night ...and they
finally analyse a low planted in the area on the 4am MSL!!

Moral of the tale? Just because it hasn't been analysed doesn't mean
that it isn't there (especially on the sub-synoptic scale) ....... keep
practising!!

Jane

Anyone looked at GASP and NGP ? Both are showing a nice system forming
on the weekend for SE States. Both have an upper trough and develope a
low in the bight with an upper low forming soon after, and the whole
system moving NE over inland VIC/NSW,  and the upper low moving towards
NE NSW/S QLD... looks somewhat similar to the system we just had. Snow,
storms, rain... all look likely at this stage, will be an interestong
one to watch !!!

Funny about this, as on the animated water vapour loop yesterday arvo,
this low could be seen quite clearly in its early development stage, but I
didn't mention it since no one else mentioned it, and so I figured that it
probably wasn't important :-(

http://www.budget.gov.au/minst/html/transp-15.htm


Bureau of Meteorology

Improved rural weather services

The Bureau of Meteorology provides a broad range of ongoing weather and 
climate related forecasting and information services to regional
Australia. An initiative aimed at enhancing the services to provincial 
cities and rural areas has been underway since 1996, with the main focus so
far being improvements to the infrastructure within the Bureau's field 
offices so that staff can respond more effectively to local needs for
information and services. In 2001-02, a further $350,000 is expected to be 
directed towards upgrading services of particular interest to rural areas,
including the development of new forecast and information products and 
improved product coverage in regional Australia.

Web access to weather radar

The Bureau has recently implemented new services on its web site to provide 
free of charge access to radar imagery from the Bureau's more than 50
radar sites and current weather information from automatic weather stations 
in regional areas. In 2001-02, coverage will be extended to a range of
250 kilometres from each location, which will increase significantly the 
regional population served.

Extensions to weather radar network

The Bureau will increase its weather radar network with the installation of 
three new radars near Canberra, Yarrawonga (Victoria) and Bowen
(Queensland) during 2001-02. The capital cost of these installations is 
about $3 million.

Some very low minima in Tasmania this morning. 

-9.7 at the new Liawenee site appears to be a new Tasmanian record
for May. This is the second successive month where this site
has set a state record - it looks quite a cold site and could be 
very interesting to watch in any winter cold spells this year.

Hobart's 1.1 was its lowest in May since 1966.

Launceston Airport is showing up at -5.0 - not sure if this is rounded
or not - the previous May record was -4.7 so it has probably fallen,
even if rounded.

if you click on it you will get the full size version.

You will also find a colour highlighted image of TC 01A in the Arabian Sea

Hi all,

Some storms around today - lets see if they can continue into the
night!  Very cold upper temps, -19.5C  at  500mb, with DP's getting into
the mid-teens WOW!  It got very cloudy and junky on the coast -
currently a broken line of storms moving WSW to the west of Brisbane -
it's difficult to guage the actual movement though as the radar stuffed
up a little while ago.  Will see in the next image or two.

Currently yellow/green/pink cells.  Certainly a good chance of hail
under any heavy shower or TS due to the cold air.  I can't believe this
is May!!! :D

There is some lightning down south towards Appin, (south west of Sydney)
and moving towards the coast. MT might have a nice view of it... bit too
far away from my position, also some nice storms on brisbane local !

I hope some people come out of hybernation (spelling) and talk on the
list.. getting a little slow lately.

Fantastic shot. Nice discrete system. JTWC predicting a curve away from
Indian Coast. Probably just as well !

Still watching the organization south of Mexico. Elsewhere, not up to much

Hi Anthony,
     You certainly have been having a good time up their this autumn :) I 
was surprised this evening to see flashes in the sky (heat flashes), then 
later noticed clouds lighting up infrequently to the south in Sydney this 
evening, havent checked any forecasts but the cloud has built up this 
evening, some with nice virga. It was May 22 last year that i went on my 
first snow chase and now its later than that and still hovering around 20C. 
The more you get into weather, the more interesting it becomes, cheers Rune.

Hi Matt and all

It was a one flash wonder this system. This afternoon at around 4pm I
remarked to a work colleague that today would have been interesting if we
had another few degrees heat at the surface. Lo and behold very shallow Cu
developed into a weak line of showers around sunset.

Michael

  recall the storm (he was probably chasing), but he wanted to hear my account 
  of it. I got some time to type it up and sent it to him only realising he had 
  flown of the US (lucky devil). Michael Bath got the report and it is now up at 
  <A 
  href="http://australiasevereweather.com/storm_news/">http://australiasevereweather.com/storm_news/</A> 
  (thanx Michael). There is no pictures because I didn't think of it at the time 
  because the storm was just so menacing. Plus like I said before I've never 
  chased a storm and thus, I don't have the equipment...</FONT></DIV>
  <DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
  <DIV><FONT face=Arial size=2>my plan in life is to become a meteorologist and 
  storm chaser.</FONT></DIV>
  <DIV><FONT face=Arial size=2>I want to be a storm chaser more than a "weather 
  man" but I would like to have the knowledge and expertise when chasing storms 
  to try an understand what the storm is doing and thus what it will do. Also 
  having a degree in meteorology ain't such a bad thing for my 
  future...</FONT></DIV>
  <DIV><FONT face=Arial size=2>Hopefully I will have my license and a car but

Even Scamander, a town on the East coast with its recording site on the edge
of the beach, measured a min of 0C.
Our min was a balmy 3C this morning but a cool -1C yesterday.
Yesterday I started my training to be a local Met observer. Encoding the
weather observations is a interesting project. Is anyone on the list a
observer?

Time for a sweet plug...

I have just uploaded my re-designed webpage, it's on Victorian weather, 
has a discussion on the current satellite situation and a model 
discussion. The notes on the sat pic will be updated each morning and 
the model discussion between 7 and 8pm, depending on time etc. A lot 
more sections will be added soon.

Yes Matt I've been looking at those, and some of the models follow the
scenario with a deep east coast low just off the NSW south coast, by
Tuesday. I suspect the weekend scenario would favour the heaviest
rainfall on the ranges and western slopes especially the south, then on
the coast south of the Illawarra early next week. UNISYS has a similar
scenario but I haven't seen many people's references to that so maybe
it's not regarded as so reliable? These anticyclones appear to be
assuming a more normal winter track in the west but in SE Australia we
seem to be having persistent cut-off or Tasman Sea lows or at least a
lot of meridionality and those southerlies that bring buckets of rain to
the coastal fringe and leave (in Sydney at least) much of the coastal
hinterland bone dry, or nearly so....

Hi Keith and all,

GASP seems to have backed of a bit in the latest run, hmmm, I'm a little
confused. Maybe I am reading it all wrong.
And hey Bussie don't worry about not following it all, we are all learning,
I know so little but a lot more than I did :)

Hi all,

Currently - I'm constructing a website of my own (slowly but surely...),
and I've been trying to decide on some names.  I would like to call it
"Thunder Downunder" - but I realise that the end of year chase is often
called this.  I was wondering, who coined this term first?  And if it
was you (or if you think it was you), do you mind if I call my website
this?  As I don't want to get anyone upset by choosing this name!  If no
one replies to this, I'll assume that no one minds...

Sender: aussie-weather-approval at world.std.com

Hi Rob and all,

While visiting DSE (Dick Smith Electronics) today, I noticed they
actually had another type of car thermo.  This one actually had an
auto-sensor that detected the amount of light, and if it got dark (ie,
night time/evening driving), it'd turn its auto-backlight on
automatically!  Pretty nifty - so nifty, I bought it to try it out.  It
comes with another power source though - the battery only runs the
thermometer LCD.  There's another plug that plugs into your ciggerette
lighter and that is what powers the backlight.  The catch?  Unlike some
of the other car thermos, it doesn't measure the min/max temp :(  I
guess it's a priority thing...I generally only use it to record mins if
I'm staying at another place - but I could always take another thermo
and do that.

Also - a note to anyone who owns a digital compass/plans to buy one -
make sure (especially in summer), that you do NOT leave it in the full
Sun!  Otherwise the LCD screen will eventually stuff up (as I found out
the hard way), it might be more of an issue in Brisbane though, since
the Sun often heats the cars much more efficiently here!  But certainly
you'd be well advised to put the compass in a glovebox, where the temp
will only reach 50C or so, instead of 70-80C!

If you want to make a tripod - Jane has something set up in her car, and
it works quite well.  Simply erect a normal tripod onto the passenger
seat of the car, and clip the seatbelt around it!  I've been trying this
out in my car recently, and it seems to be quite stable and sturdy! 
Best of all, it's completely removable if you need to remove it.  Only
drawback is it's difficult to see what you're videoing, but if you want
to video while driving through heavy rain/at night for lightning etc,
it's quite good!

If you want to get rid of musty smells in your car (obviously you often
get wet every so often, or your shoes are wet etc) - DSE has a niffty
little air freshner that also plugs into the ciggie lighter, and it only
works when the car is on - but it does help give a light pleasant odour,
rather than an overwhelming smell that other deodourisers give.

And last but not least...the other thing you can do, and I've find works
well - is place little moisture absorbers under the car mats.  This just
helps if any moisture gets underneath the mats - they are absorbed
nicely.  It doesn't help in the short term - only the long term, as it
can take several days for underneath the mats to dry!  Especially if
you've done a lot of chasing recently, or gotten quite wet!

Calder Park raceway down here in Melbourne used the phrase 'Thunder
Downunder' to advertise the first NASCAR race at the Thunderdome in the
80's.

I also have a nice 'Thunder Downunder' t-shirt, from of all places, Kansas.
I picked that up from the B-1 crew at Avalon airshow.

The new Bureau rainfall data I mentioned in my post yesterday is great, but
accessing it is hard work with many menus to go through.

I've put up a shortcut method of access on my site -- follow the link on the
right of the main page at http://www.australianweathernews.com. Only NSW
regional data at present; other states coming.

I have also set up several pages that amalgamate the rainfall graphics for
all states -- handy for getting an overview of where the action is.

Hi Lyle,

I use Ulead Pan 360 - does a good job, but you have to be patient.  The
main problem I've come across, is the different light on different parts
of the pan, so sometimes you get faint white areas over the joins as the
program attempts to blend them in.

Two examples I've used:

http://www.bsch.au.com/anthony/281100pan1.JPG  3 photo shot of a storm
in the central slopes/plains of NSW

http://www.bsch.au.com/anthony/041100pan2.JPG 3 photo shot of a
supercell to the west of Brisbane

Visitors more than welcome!

Just a reminder that The next QLD ASWA Meeting will take place 
on tSaturday, the 26th of May.  Time will commence at 10am as 
usual at the usual venue of Spherion Technology, Level 4, 200 Creek 
St, Brisbane. 

There's quite a few important items that need to be discussed 
- especially in preparation for state rep elections, and 
housekeeping matters - so it would be great to get a good turnout for
some 
comments and feedback!  ASWA car stickers will be on sale for $4 each, 
and for those whose membership falls in May, it would be a prime 
time to renew 
their membership! 

April and May have been very interesting weatherwise, and 
there'll be lots of footage from these months to display! 

A few highlights come to mind: 

- April 26-27, inland trough, nice well developed wall cloud, 
and video footage of 100km/h+ winds from a microburst 
- May 6th, cold pool - gave huge hail drifts still nearly a 
foot deep 18hrs after the hail fell!  Footage of this 
- Recent May storms from late last week in SE QLD - some 
lightning/thunder footage, and lots of hail drift/damage assorted storm
footage 
from these days! 

As well as some "Thunder Downunder 2000" chase footage that 
I'll bring, so plenty of new stuff to watch!!!  We'll also look at 
a recent event in depth (probably the the May 6th cold pool), 
and have a look at the mechanisms at work - in particular for NE 
NSW. 

The details recapped: 

Date: Saturday, 26th of May 
Time: 10am - if you come late, phone 0417 759 304 and we will 
send some one down to let you through the security. 
Venue: Spherion Technology, Level 4, 200 Creek St, Brisbane 
(Right next to the Novotel) 
What to bring?  Yourself, storm footage/photos you want to 
share, any visitors, $4 for pizza and drinks. 

If you can come, it'd be great if you could drop a quick email 
just to let us know for numbers! 

Look forward to seeing you there!

Actually, I think from memory that Jane came up with the term for
chasing...don't quote me on it though, but I don't see anyone having any
objections with it though Anthony.

Calder Park raceway down here in Melbourne used the phrase 'Thunder
Downunder' to advertise the first NASCAR race at the Thunderdome in the
80's.

I also have a nice 'Thunder Downunder' t-shirt, from of all places, Kansas.
I picked that up from the B-1 crew at Avalon airshow.

Most often a sporting type term - I thought it was something to do with
cricket.

Evening all (yep I'm still alive)

If you want lots of reading.....

there was the inaugural ''chase' in 1998 written up....
Michael Thompson's report
http://ozthunder.com/chase/tour.htm
Clyve Herbert's synoptic analysis & synoptic description
http://www.stormchasers.au.com/stormchase98.htm
http://www.stormchasers.au.com/98synoptic.htm

.......................but on to attempt an answer to your
question........................"ThunderDownUnder" was the name we gave
to the 1999 'chase' which saw 14 weather enthusiasts explore the SW of
Queensland, the western areas & the SE of NSW in late November - early
December.
http://www.stormchasers.au.com/tdu99.htm

The name got shortened to TDU2K (ThunderDownUnder2000) ...........
my pics
http://www.stormchasers.au.com/tdu2kjon1.htm
Michael Thompson's report
http://ozthunder.com/chase/tdu2k_1.htm
Matt Smith's report
http://www.sydneystormchasers.com/2000/TDU1.htm
Andrew McDonald's report beginnings
http://www.stormchasers.au.com/tdu2kam1.htm
Jimmy Deguara's report (3 'episodes')
http://australiasevereweather.com/storm_news/2000/docs/0011-08.htm

& this year there will be TDU2K01 (ThunderDownUnder2001) - then in the
future we have "ThunderDownUnderUpOver" - which is us in the Plains of
Oklahoma, Texas & anywhere else there is severe weather - how's the hail
over there Jimmy?????

I can't remember who should be'blamed' for suggesting the name - but I
think we 'field trippers' can take the credit for its evolution last
century <g>

Sorry AC, did I steal your thunder?? <g>

HI All..

With the possibility of snow around the Central Tablelands and Blue
Mountains soon, I have made a simple page up for road reports and closures,
also any reports of snow I hear in Bathurst /Orange/Oberon area.    My
radio scanner will be tuned to Police and any updates I will put on this
page..

http://www.nia.net.au/~davidkc/snowreports.html .

As I did last year and many people appreciated the reports i gave.. If
unable to update page, will send emails and list on weatherforum..

Dave
Bathurst.

Afternoon all,

There's a small mid level low east of Esperance which formed this morning
and is currently rolling up around the coast of the Bight (and hopefully
down the other side and across Victoria). It shows the leading edge of cold
air at 850hPa & the strengthening jet. 500hPa temps at Mt Gambier
were -20.9C this morning & -25.9C at Esperance..........

Interesting to watch this development within the developing situation today,
tomorrow & Sunday.

Hi Jane
2 days ago it was -25C at 500 here in Sydney... quiet amazing, back to -20 now

Next system looks interesting, monday will be cold... strong SW winds and an
upper trough pushing through NSW
http://www.bom.gov.au/fwo/IDG00V56.gif?20010319044637
That stuff in the bight is the start of it no doubt. Hope the models hold true
with this system.

BTW has everyone been looking at the states lately? if not, bookmark this page :

http://iwin.nws.noaa.gov/iwin/graphicsversion/bigmain.html
current sats/radar/warnings, great page for nowcasting or for a quick glance at
what is currently happening in the US.

Also it looks likely that I will be moving in the next few weeks to Newcastle.
Based in the Hunter.. cant wait till storm season.

Hi all,

Pretty average static on the AM band currently, few nice burst every now 
and then, counted a couple at 8 seconds. I have seen a flash of Lightning 
to the NW, it was pretty far out. Adelaide broad is looking more droolable 
each update, but most of it seems to be headed too far south to hit 
Adelaide. Satellite picture look very nice aswell.

Anyways BRING IT ON!!!!!!!!!

Hold it off... Hold it off!!

My last MTB ride in Victoria tomorrow, and miles from nowhere... I'd like to be
back in Melbourne before it hits, so I can enjoy it with a drink.

Lightning tracker is showing some wonderful fireworks, and it doesn't seem to be
slowing done. Finally a good one in Vic, and none too soon.

Hopefully Sydney puts on a few more storms than we have had so far!

I live in Holland myself.

It might be a good idea for them to go to aussie..  Since over in Holland it
rains alot, but never really storms, or has much exciting.

Your reports last year certainly were appreciated. Let's hope you get a
chance to give the page a workout over the next few months.

Who jinxed Adelaide's chances of getting good storms!!!!?

Seems this is happening quite frequently lately. Is anyone to blame for this?

Last night we had a couple of strong bursts of wind which I was told was 
from a roll cloud that went over Adelaide. I had just gone to bed when it 
happened, by the time I  was woken up and went outside for a look, all I 
could see was cloud and no rolling. The lightning frequency had greatly 
diminished (I did manage to see two flashes from lightning far far away.) 
and started to look like our chances of getting a storm were fading by the 
minute. I kept telling myself, we are going to get one.
After waking up this morning, I knew our chances of getting a decent storm 
had gone, but we are getting the rain we so badly need for our gardens. 
Wind is not too strong here atm.

How is everyone else in Adelaide going, I have 6.5mm in the gauge now, with 
some more coming by the looks of it. It's fairly cold outside about 12c and 
we have moderate winds gusting to about 10-15 knots occasionally.

Hi Andrew

I have over 15mm in the can now, still falling quite heavily.  Absolutely
no electrical activity here at St Peters.  Cold though, only 11 degrees
here.  How did you hear about this roll cloud?

I'm thinking I might head to the beach tomorrow morning if the 2nd front or
the cold sector air arrives in a timely fashion.  Anyone notice how 90% of
the fronts seem to cross Adelaide at night? [yes, I know the nights are
longer than the days in winter, but it seems like ages ago a decent front
arrived during the day.....]

Phil

Hello Phil

It would be nice to know statistics on the time cold fronts cross the coasts.
When I lived in Perth WA I always thought there where more cold fronts at night.
Now I live on the West coast of Tasmania I also have the same opinion that cold
fronts mainly cross at night.

 The icy southwesterlies certianly came as predicted this week. The deep
south took a prolonged lashing, with snow down to sea-level in Southland,
South Otago, Dunedin, and even parts of the West Coast. (snow was lying on
South Westland beaches early on Wednesday) Canterbury got off lightly, but
there was a brief heavy snowfall over Banks Peninsula on Tuesday night, and
some mean frosts in Christchurch. It did get milder for a time on Thursday,
but it's now getting cooler again, and another cold outbreak is forecast for
tomorrow - snow showers to about 300 metres in the east of South Island.
 Late May 2001 in NZ is shaping up like late May 2000 was over SE
Australia!. But our very cold outbreak seems to have sent its worst only to
the higher latitudes so far - the North Island has had cold southwesterlies,
but nothing too much colder than usual. BTW, SE Aus looks like getting a
cold outbreak soon, but it doesn't appear to come anywhere close to the
events of a year ago.

Yes Andrew that roll cloud you metioned was very interesting, I watched low 
level clouds quickly roll in from the coast, then all of a sudden some huge 
gusts of wind developed here, lots of uplift of leaves vertically etc. all 
as the cloud moved over.  There was some serious rolling going on, scud 
everywhere, then some very brief lightning as it pushed into the SE Adelaide 
Hills.  Some ok falls of rain so far in Adelaide.  System approaching from 
the SW looks very interesting with a heavy upper level influence associated 
with it, could and I only mean could because I don't want to get my hopes up 
get some very heavy falls here tomorrow morning especially, really hope 
BOM's forecast comes true for tomorrow. Being tucked in near the hills here 
hoping for those possible heavy falls mentioned in the forecast.  I am very 
prone to slight orographic rain here, (because we don't get true orographic 
rain due to the height of the Ranges), I'm not complaining though:)

SA radar looks very impressive at the moment with the the next front now crossing
the Yorke Peninsula and Kangaroo Island. Latest radar pics have quite a bit
of pink and green heading our way although the lighting has died off and doesn't
look like affecting the city. 

The Bureau has issued a severe wind advice for Lower Eyre Peninsula, Yorke Peninsula,
Kangaroo Island and Mt
Lofty Ranges south of Adelaide.

SEVERE WIND ADVICE 

Severe winds and squalls associated with thunderstorms are possible in these

districts  Lower Eyre Peninsula, Yorke Peninsula Kangaroo Island and Mt Lofty

Ranges south of Adelaide Lower Eyre Peninsula, Yorke Peninsula Kangaroo Island

and Mt Lofty Ranges south of Adelaide during the next three hours.

A frontal band currently near the western end of Kangaroo Island is moving east

at 70 km/hr. Squalls to 90 km/hr are possible and may be associated with
thunderstorms.  The State Emergency Service advises that people should secure

loose outside objects. Driving conditions may be hazardous.

Some excellent winter weather just passed through Adelaide from about 2:30am 
to 3:00am.  Was woken up at about 2:00am by some rain, then noticed some 
lightning and some rumbles of thunder to the south.  The rain soon became 
torrential and some hail as well, the thunderstorm rumbled as it moved over 
here and became very lightning active when reaching the Hills.  A few deep 
rumbles out of it nothing really really sharp except as it passed over.  I 
don't care how fast the rainband has ended up moving we have finally got a 
winter thunderstrom in Adelaide!!!  Can't wait to hear reports from Andrew 
and Phil etc bet they are out chasing, I'm too lazy;)

Sitting at work I was watching this system come in from the Yorke Peninsula for
about an hour, it didnt look that exciting until it hit the coast then it went
crazy. Quite a bit of close lightning around the city as well as some hail,
very gusty winds and very heavy rain. Many areas received 10mm in about 30 mins
from this band. Its now tracking east and is out around Murray Bridge.

Going out for a drive I found quite a few areas that have minor flooding, and
listening to the scanner the emergency servics are busy with trees down and
other wx related incidents.

All up a very good little system for us weather starzed Adelaide people.

Cheers

Matt B

Hey SG,

Unfortunately I'm a bit crook at the moment, so there's no way I was going
chasing at 3 in the morning!  Yet another frontal passage at the most
innacessable time of the day!  But it definitely woke me up.  Quite a
lightning active winter thunderstorm, not just the one flash bang type.
Mostly CC but I saw a few CGs.  And that strange 'soft' thunder you get
with winter style storms.  Some good strong gusts and brief ricegrain hail
too.  I expect to see another 20mm or rain in the can when I check it, so
May, after starting warm and very dry, has in about ten days become a month
of above average rain!  Don't ya love it.

Can't see much in the cold air field, but it will be worth watching the
satpics for any comma clouds or secondary vorticity during the day.  We
might even hear a report or two from the hills about a coldie or two.

Now - all I'm asking is for that again [but stronger], during a day I can
chase!

Phil

I missed it all, only got light to moderate rainfalls and a little bit of 
wind. With no car right now so I couldn't chase either.

Hi all,

If you looked at Oakey's obs (QLD) this morning, check out the
temperature rise!

5am:  1.8C
6am:  1.1C
7am:  2.2C
8am:  9.4C
9am:  16.7C
10am: 21.0C

Not sure if this is unusual for some places in Australia, however still
impressive, normally Oakey would struggle to get to 20C after a night
near the negs - NW'lies are responsible.

Hi all,

At the QLD ASWA meeting on Saturday, we held a brief dicussion on the
unusual storm season, in particular for NE NSW and SE QLD.

I produced this image:

http://www.bsch.au.com/anthony/StormEffect.jpg

It displays the number of thunderdays for each day, for the past five
days (courtesy of James Chambers' information), and there is an averaged
out line of the graph to show you the unusual anomaly.  I have also
indicated on here, the most likely reason for it.

Shame Dave Ellem (Michael Bath's storm chasing partner) couldn't come to
the meeting, as I am sure he would have enjoyed the discussion!

We got the northern end of the storm here at Newton (NE of Adelaide)
about 3am. No hail, but very heavy rain - 15mm in 20mins. (30mm to 9am
this morning, 42mm in total from this system since 10pm Friday).
The radar loop of the squall crossing the coast looked very
impressive, and it was nice to see some lightning once again!

Hi all,

Finally have done my May 17th chase report - received a funnel, dozens
of trees down and one foot hail drifts!  Unfortunately due to the speed
of the storms, I wasn't able to get much footage, so not as many
captures as usual.  But captures of the hail!

Riding into work this morning was made so much easier with three very dark areas over a dark and promising ocean horizon with lightning flickering away, and beautiful fibrous anvils pushing back SW over the coast from probably 50kms+ away. The remaining horizon from the NE to SE has cumulus pushing up behind the cells to continue the storm. It will be interesting to see just where along the coast the low sets up. Could this system be enough of a primer for a bomb to go off just off the Sydney/Illawarra coastline?? We can only hope!!

Temp was 11.5C in Wollongong at 6:00am with a light but cool SSW wind blowing to slow the bike trip into work. Still, a very nice way to start the week. Bring on the cold, wet and stormy stuff.

Hi all,

Seems to be a shallow layer of dust has enveloped the Norther Rivers area 
on NSW. Anyone else got this - Brisbane ?

Or is it just haze? We have a fresh gusty W blowing which usually brings 
crisp clear skies.

Hi Anthony,

Another interesting read AC, great work! WOW - 11 chase reports this year 
already.

Thanks for putting on another QLD ASWA meeting on Saturday. Those attending 
got to see Anthony's recent storm chase footage including the 17th May and 
to discuss the recent unusual weather patterns.  Well worth the drive up to 
Brisbane for me. I hope a few more Brisbanites will come along to the next 
one !

Hi Chas,

As far as I know there is no reason frontal passage to prefer any time of
day, other than Murphy's law for chasers... :)

John.

>snip

It would be nice to know statistics on the time cold fronts cross the
coasts.
When I lived in Perth WA I always thought there where more cold fronts at
night.
Now I live on the West coast of Tasmania I also have the same opinion that
cold
fronts mainly cross at night.

Hi,

Some comment on where we should have radars in NSW:


 From ABC North Coast
http://www.abc.net.au/news/regionals/northcoast/reglis-28may2001-3.htm

Farmers' group seeks
storm-tracking radars

The New South Wales Farmers Association says the
weather bureau should establish storm-tracking radars to
warn north and mid-north coast communities of severe
weather events.

The Budget allocated funds for a new radar station at
Canberra, but left out an area known as "thunderstorm
alley", where severe weather events spawn and head
towards northern New South Wales.

Association senior vice-president Xavier Martin said new
radars at Dubbo, Gunnedah and Walcha would fit in with
existing ones at Grafton and Moree.

Mr Martin says the area where storms build up is a "black
spot" in the weather radar network.

Hi Andrew !

A veryyyy small surface low formed over the Central coast/hunter coast yesterday, this directed E/NE  winds in towards Sydney in the afternoon, the little bit of added moisture was just what was needed to trigger storms. (freezing upper levels of -24C  at  500 and a the jet slowly moved down a bit, so we had about a 60knot jet, aided in lifting), this low moved out to sea and is the low in the tasman you see now growing !
Of course yours truly was stuck at work from 6pm onwards and missed it all.

Could this system be enough of a primer for a bomb to go off just off the Sydney/Illawarra coastline?? We can only hope!!

Hi all,

Yep, we have what appears to be haze in Brisbane in a colour I have not 
seem before. Maybe a combination of dust with a slight smoke/pollution 
element? Very unusal because as you mentioned Michael we usually have 
clear skys when we have strong winds from the south west/west.

Hi all,

Seems to be a shallow layer of dust has enveloped the Norther Rivers 
area 
on NSW. Anyone else got this - Brisbane ?

Or is it just haze? We have a fresh gusty W blowing which usually 
brings 
crisp clear skies.

Michael

A tremendous line of storms is moving through the whole state of
Oklahoma at the moment, every warning you can
imagine is out.

Check this image out from one of the TV stations, from the front line.
Every chaser on this list will drool over thi pic...
it is the shelf cloud lite up by lightning at 10pm, and Anthony , it is
more impressive than the one you saw near
Beaudesert that time (when you met up with Jame chambers) and THAT was
impressive !

Jimmy/David must be having a ball there at the moment, anyone got
updates from them ???

Hi All.

Hurricane Adolph off the W coast of southern Mexico has intensified very
quickly to a US Category 3 cyclone. It is likely to intensify further and
still has the forecasters stumped as to which way it is going to go. It has
a well depicted eye in the satellite imagery.

Also Tropical Cyclone 01A in the Arabian Sea has lost some of the intensity
it had a couple of days ago - it was the most intense cyclone ever recorded
in the Arabian Sea.

Links to all warnings etc are on my webpage at
http://users.ace-net.com.au/~carls/current.htm and you can see some
coloured satellite images of these systems at
http://users.ace-net.com.au/~carls/currenttropical.htm

Latest Adolph advice pasted below.

Regards,
Carl.

But it is based on ancient history...
On the Bellarine Peninsula it shows Marcus, Wallington and St Leonards 
(three tiny places) while completely ignoring Drysdale, Port Arlington 
and Queenscliffe (three much larger settlements).
The Queenscliffe railway is shown going through to Moriac but with no 
connection to Geelong.  And Leopold is missing!
Whoever drew the map is utterly unfamiliar with the area.
This is the only area I checked so far, but I think a greater accuracy 
would be highly desirable.

I've just been looking through a few more of my favorite stamping grounds 
from around Victoria and found that a vast number of good sealed local 
roads are missing even when zoomed right down to 1:200,000 which appears 
to be the closest one can get in Australia.
However, after having been critical, I have to say that I do believe it 
is better than a lot of other on-line maps I have used.

There you go Anthony, it hasnt updated for a while now, i suspect alot of wind damage
throughout the state, or a lightning strike is the reason for no update.

Still there are meso's all over the place and VERY VERY strong winds and large hail.
I hope people dont mind the posts about US weather... this list is really quiet lately.
Jimmy/Dave will be having a field day... lightning show must be spectacular through
the whole state/

Hey People
I know it is a long way out but both GASP and NGP are looking quite 
interesting for next week. Both have a deep low pressure system and 
strong front south of the bight. Thicknesses associated with this 
system are very low, below 520 and the thickness gradient is very sharp 
(rapid cooling of the upper levels). What this system does will depend 
a lot on the high to the east (the one which will plant itself over the 
SE for this week). Hopefully the rigde over SE Australia will weaken.

Thanks for that. I've rediscovered a site I thought I'd long lost - I can

Carl

How low can he go ? I think at least a Strong Cat 4 (say 930hpa) by
tomorrow. Probably a WNW track then W, and then the usual rapid dissipation
as he encounters severe wind shear ???

Interesting to observe a couple of other cyclonic swirls affected by the
same strong upper outflow - one now over the Yucatan Peninsula the other
well south of Bermuda. Neither look too exciting at present, but over the
next couple of days may be 'spun up' by the same strong outflow.



Regards
Simon

I zoomed in on the Mudgee area out of curiosity. As you mentioned the roads
are a bit ' iffy ', but the creeks and rivers seem very accurate.

I have always been told that if you stand on the main street of Capertee (
south of Mudgee ) that the rain in the west gutter runs into the Murray
Darling system via the Turon and Macquarie rivers, then to South Australia,
whilst the rain that falls on the east side runs into the Fish River and
Nepean Hawkesbury system. Looking at the map I cannot fault it as it has
east and west flowing rivers dead on the road at Capertee.

On the other hand I notice it has a road from Orange to Hill End. In the
real world there is a such road, but it is 4WD track and includes a no
bridge crossing of the Macquarie River.

Hi Matt and all,

I got a brief e-mail from Jimmy yesterday.

Most of the libraries where they are do not open until 10am and then they 
use a lot of their time checking the models, with e-mail the second 
priority. :-)

Jimmy and David's biggest problem is that their South Pacific Pesos have 
very limited buying power in the US so renting and running the car and 
getting accommodation that is not glorified slums is using up a lot of 
their resources.

They did meet with Tim Marshall on Friday, I think. Jimmy was very 
impressed with Tim's room full of tornado photos! :-)

Over the weekend they were intending to move into north west Texas. If they 
did, then they would have been in perfect position to intercept yesterday's 
action as it moved through Oklahoma.

It is just on 6am Monday morning there now. I'd say that in 5-6 hours time 
we will see something from either David or Jimmy. There may even be further 
action today....

Geoff

I think Chris's explanation is fair spot on. The term is pretty hard to
trace. My father thinks 1983 Americas cups, the American press referred to
the aussie performance as thunder from downunder, which is pretty much the
same thing.

Yeh - the old story that the USA is cheap is not at all true. Even the 
price of petrol here now is no cheaper than in Australia (about US$1.90 per 
US gallon), and the prices for most other things are much more expensive 
(often dollar for dollar the same price, which makes them about twice as 
expensive in real terms).

There's been quite a lot of talk here in the US about replacing the 
windchill scale with something more practical. As it stands, windchill 
readings basically tell you what temperature it feels like if you're 
standing outside in the wind, stark naked - so unless you're into 
stormchasing in the buff, it doesn't mean that much. From my own experience 
over the long cold winter we just had in Madison, -20C temp. with no wind 
feels *much* colder than, say, -20C windchill with 0C temp., at least when 
you're well dressed.

G'day Iain and all,

Yes, I tend to agree with your thoughts on windchill etc. We've had wind
chill of roughly -5 to -11 here this morning and really it hasn't felt that
cold, to me. Even our windy/snowy, amazingly cold outbreak of  late May last
year didn't seem very cold to me and that had wind chills of  below -20. Our
Oberon cold from last year of nearly -10C (Where our cabin was at the bottom
of a valley with 1150 to 1250 metre hills around it) felt much colder. Of
course that was in dead calm conditions, ideal for radiative cooling and
down-slope winds. The frost was ten to fifteen feet high in the trees and
hoar frost feathered over all of the windows. I have the photos :)

Wind-chill is something that needs to be looked at, I'd say.

Lots of rain in coastal Sydney overnight. Generally from Homebush
eastwards haev scored the best rain
with 50mm+ falls since about 8pm last night,  1 report of 87mm in Sydney
which is a very nice total.
42mm at my place to 9am.

Hi all

On Sunday I made a purchase of a Radioshack max/min digital car
thermometer which has a backlit display for $35 from Tandy.  
http://www.tandy.com.au/shop/viewproduct.asp?sku=1003597&sn=gad

I wouldn't rush out to buy one though, as in my opinion, it isn't all that
its cracked up to be. 

It seems that the only way to reset the max/min temps is to take out the
battery, which at first doesn't seem too bad.  However, the fact that the
battery cover is held in with a screw makes this task a little more
harder. 

To activate the light you press a button, and the light is supposed to
last 5 secs before turning off.  I turned on the light on Sunday night and
found that some 3 hours later it was still on!!  This may be a good
unexpected feature for nighttime driving, especially since the buttons are
small, but by the next day, the battery was on the verge of conking out.

So I returned this and went to Dick Smith and opted for this one:
http://www.dse.com.au/cgi-bin/DSE.storefront/3712359/Product/View/Y5037
It doesn't do max/min, but the light button is nice and big to press, and
the light actually turns off!!

Anthony's autolight one is this:
http://www.dse.com.au/cgi-bin/DSE.storefront/3712359/Product/View/Y5006

Another slimline one is this:
http://www.dse.com.au/cgi-bin/DSE.storefront/3712359/Product/View/Y5007
but it doesn't have a light.

There's this one which measures humidity as well, but what it doesn't say
is that the humidity is measured on the inside, not with the external
sensor.
http://www.dse.com.au/cgi-bin/DSE.storefront/3712359/Product/View/Y5189
This is also much larger than the other ones.


Cheers

Hi all.
A marked convergence line looks interesting over the south west of WA at the
moment. Some rather large anvils one of which seems to show a slight
anticyclonic curve this area looks like it may generate some good storms
today especially with a thermal trough moving over this region later
today,there seems to be a risk of a possible severe storm or two this
afternoon.

Wollongong 14:40 EST,

A very nice coldie just out to sea at the moment, a little SE of the Wollongong CBD. Very nice looking tops which are quite high and rainbow. Massive anvil spreading NE, nice and thick with plenty of mammatus underneath. I like the looks of this and can only assume it comes ashore in about 40 minutes time as I run home from work and get saturated and soaked like this morning. You Sydney-siders should be able to clearly see this down to the SSE.

The views out to sea have been very nice, with a beautiful sunset last night of large cumulous and cbs and anvil reflecting different colours to the ocean just on dark. We may not have seen much eventful weather on land but it is great to look at anyway. Love this cold unstable weather, we just need a nice little spurt of extra cold for some crystalling stuff to fall from the skies now!!

Sender: aussie-weather-approval at world.std.com
Reply-To: aussie-weather at world.std.com

Hi all,

I was just wondering on the possibility of sleet/snow in the NE NSW/SE
QLD ranges overnight?  In particular between Glenn Innes and Armidale,
some obs of interest:

ARMIDALE AP AWS1600 SW /020  7 1018.0 
GLEN INNES AWS 1600 S  /020 10 1017.4                                   
GUYRA          1500 SE /009  6          0.2    DRIZZLE  5000m
STANTHORPE      1600  SW /008  12  1017.0

Many of these places will get to around zero overnight, and there are
currently showers around - and they look like they'll continue with the
instability from the cold air aloft!  Stanthorpe is around 800m, Glenn
Innes around 1080m, and Guyra (the most likely to receive anything of
all), is about 1200m above sea level I believe.  I think the possibility
definately exists, as in Toowoomba this morning at 6:30am, I was
registering a temperature of 4.7C, with light rain!  The snow line was
approximately 400m higher (Toowoomba is 650m above sea level), so the
snow line was a little over 1000m.  The air aloft is even colder now! 
So will be interesting to see what happens.

Any thoughts/comments?

Yeah they are huge. Just back from taking some photos of their sunlit
brilliance. They must be pretty high as we can rarely see them so clearly
from Blaxland.

G'day Anthony and all,

I'm not sure about your area, someone more qualified may answer that one but
let me know how it goes, I'm definitely interested. It's currently just over
6C here and drizzling. Katoomba is forecast for 3C overnight and the chance
of a morning shower, so you might see sleet here, or more likely out west if
the showers remain there overnight.

Hi Simon,

I agree that wind chill factor should be given out - it's very useful! 
Especially in cold and windy places like Toowoomba - when the
temperature hovers around 12-13C for most of the day - with howling
S'lies, and the temperature feels more like in the negatives!

Hi Robert,

In order to clear the min/max on the Tandy ones - you have to press the
"min max" button for about 2 seconds, and it resets the display!  The
backlit thing is weird, sounds like you got a lemon.

I am trying out the auto-backlit one at the moment, I've found it
brilliant for the night driving I've done so far!  But you need to
connect it to your ciggie lighter in order for the light to work.  This
is good though, as otherwise you'd waste too much battery power!  

It's a shame about the min/max though - wish they would combine all the
features!

UNISYS is still holding out for a deepening low crossing Victoria
although the real deepening is to occur in the Tasman Sea. Perhaps it
likes these cut-off lows..it has another one forming over WA at the same
time. I think that's a bit unrealistic..the prognostic looks like a
February map. (I wish the weather would feel like it)! But if I recall
correctly, this model accurately forecast several days in advance the
last upper depression that brought the heavy rain to the north coast (or
it might have been the one before).
By the way, can anyone point out the difference between baroclinic and
barotropic? Is it something to do with warm and cold occlusions?

Guys,

The one particular coldie which captured my attention bit the dust within
minutes of writing the email. I didn't see another with an anvil spreading
NE after it, they all seemed to form to the SW as if the lower portions of
the cb's were moving faster than the upper. It would seem that the downdraft
rapidly became dominant in this case as suddenly there was a line of scud as
the coldie moved ashore with very little left of the base features which I
saw only minutes earlier. But still some great clouds about, hopefully we
will see much more during the winter.

Keith,

Baroclinic conditions (we love to love these!!) are simplisitically
where the isotherms cross the isobars at an angle eg: fronts & troughs,
so that there may be cold or warm advection.  In barotropic conditions
(where we all go into hibernation & find something else to occupy our
time), the isotherms are parallel to the isobars & no advection occurs
(hmm, stable weather).

Hi guys,
        Can't help but remember the last year these upper cold pools and 
associated coastal thunderstorms continued to drift by.
       That year was 1997, a sensational winter for anyone on the eastern 
NSW coast. CBs were continually out there, even on a fine day nudging closer 
to land on every cold change arrival. The occasional one would strike the 
coastal suburbs bringing flash flooding and irregular deep rolls of thunder. 
I recall that year was a poor ski season and one with a few late season 
ECLs. I know things were alot different back then eg el nino, but i recall 
that following summer as been sydneys and much of eastern NSW hottest 
(sydneys 2nd hottest). Wetstern sydney would on regular occassions hit 40-43 
with the city not falling much below 29. This may all sound like rubbish 
talking about these sought of things, however, i have found on previous 
occasions seasons can be predicted through  types of recurring weather 
patterns. Anyway heres me thinking of summer, guess it makes me feel better 
talking about it.
     Anyway, lets hope winter does something exciting for ALL of us 
including the Perth , Adelaide, Tassy, and Melbourne lot.
REGARDS
JAMES Sydney (With the in car shower and those PASSING thunderstorms)

James... are you saying Perth, Adelaide, Tassy, Melbourne dont get weather ? :)

If so, you forgot to include Canberra ;)
Just kidding guys

More stuff from the states. This chaser got hit by 106mph winds from a storm,
and has video captures up (that is close to 170km/h winds) awesome stuff !!!

Hi,

Colorado got some nice storms the last two days. I missed these but with due
cause as I was backpacking in Yellowstone for a few days - saw amazing
wildlife up close and personal (Bison, Elk, Moose, Bears and even a wolf!).
But on the way home through Wyoming we drove right around a nice supercell
so everything was good - some chases at CSU caught a tornado - oh well ;/

Hi Iain,

I'm not sure who spread that nasty roomer that the USA is cheap because I
thought that too when I came here. As far as things go, everything is much
more expensive, especially quality stuff - ie bikes, furniture etc. I'm
earning US dollars so it's ok now but to travel here on the aussie dollar
would be real expensive!

Cheers, Lyle

Hi everyone,

Just a quick note to say I was pleased to see on the WIN/Nine news weather report last night that they included a warm front on their synoptic chart for today. It extended from between the forecast two high pressure centres south of Adelaide, where it was shown as an occluded cold front, then became a warm front which swung into the low centre SW of WA. If would have been great if this was to have crossed land, but it was a little too far south.

I didn't notice it on the Channel 10 chart, but it definately wasn't on the Seven chart. But it was good to see something that I have never noticed on the commercial stations forecasts before.

Canberra got -6.0 last night, its lowest May minimum since 1982. The
record is -7.5 (set in 1976).

Nothing so interesting in Melbourne; there has been very little 
variation in temperature since the 17th. If the forecast of 15 for
the next two days is realised, the 15-day standard deviation for
the period 17-31 May, for maximum temperature, will be around 0.6-0.65,
which would be the lowest for any 15-day period since 1923.

Hi folks,

Tornado Alley is (as I type) experiencing its best day of
the season thus far.  A line of tornadic supercells is 
moving E through the E panhandle ATM.  Large tornadoes
are a likely possibility.  If these hit something, we
should hear about it in the news soon.

Check out 

     http://www.wunderground.com/data/severe/current_severe.gif

for the assortment of SVR/TOR warnings and the SPC watch boxes.

Gee, if this keeps going I won't get any work done,

Harald

The Perth broad radar loop is interesting, love the rotation on it, not
often you see that.

BoM have the low at 32S115E, which makes it about 100km due west of Perth,
the centre of the low is at 1006 hPa, its too bad its not well below that,
or we might have been getting gale force winds here.

Hi all,

I got out of work early - and was able to head out to Cleveland Point to
have a look at the storms out to sea.  Unfortunately they were at their
best (as in, awesome for even a land storm!) between 11am and
midday...and I didn't get there until around 12:45pm, after which they
fell apart.  But I did get some footage, and decided to try and put it
into a time lapse.  It didn't end up being as good as I hoped, the
storms weren't particularly dynamic (the reason why the lapse wasn't as
good as it could be), I also had the exposure on a tad too bright!

Anyway, it's 2.9mb and in avi format - about 25mins of footage condensed
into 13 seconds.

Let's hope the cloud links up and doesn't get blown too far east....

Hi Iain

I started out to disprove you on Petrol price and must admit I have to eat
humble pie.

Price here for unleaded in approx 95c per litre.

There are 3.59 litres to a US gallon. Price for US gallon in Australia 3.59
x .95 = $A3.41

One Aussi dollar is worth about 52 US cents, therefore 1.90US per gallon is
= $A3.59 give or take a cent.

Michael

 Could be some record lows over the inland South Island over this last week,
possibly here in Christchurch as well. (mean frost this morning) Twizel (at
about 500 metres asl in a basin area not far from Mt Cook) had freezing fog
on Tuesday - the maximum apparently only got 'up' to -5!) The North Island
hasn't escaped the cold either - maximums of only about 8 C in places like
Hamilton, Taupo, and Rotorua over the last few days. This was due to cold
southerly air undercutting cloud spreading from a low pressure system to the
north. A light dusting of snow fell on Mt Pirongia, a 900 metre high
mountain west of Hamilton, yesterday. More snow, however, on the main
skifields, most of whom now have a decent coating.

GASP prog indicates a NW cloud band stretching from Sydney through to the
Pilbara coast on Wednesday night (+7 day prog). Tracking through the charts
it seems to be the same cloud band that is over WA at the moment - or
perhaps a resurgence of the same cloud band as it appears pieces will drawn
off through the week as fronts pass to the south.

Hi every1,

I'm not sure exactly what sort of storm I managed to catch on the Amarillo 
weathercam this morning...but I offer it for comments...from the shadows on 
later shots I think it's facing roughly NE from Amarillo...

Cheers,
Kevin from (a very cold) Wycheproof.

P.S. Karen, hope you got some great virtual snaps too!

Why is it Katoomba's night temperatures are no where near as cold as everywhere else

Hi Tony,

It certainly was a cold start, there was even some frost in a couple of open areas in Wollongong. We only got down to 6 degrees when I left to run to work this morning at 5:20, so it was wrap up time.

If I was to have a guess as to why Katoomba doesn't get as cold as places like Goulburn I'd say it is to do with topography. Katoomba and areas around are on the tops of the ranges and would only really experience what the true atmospheric temperatures are. This would probably be very different in the deep valley floors, but I'm generalising here. The difference I feel with places like Goulburn, Bathurst, etc is that they sit in lower parts of the land as to what exists for a fair area round them and as such the colder air has a far better chance of sinking into these areas and getting even colder. My experience also, on a much smaller sclae is that with open grassland and parks on the way to work, the air gets much colder around these and if this air then spills into a hollow nearby, that hollow gets extremely cold compared to the air around it. On nights like last night, a distance of around 1.5km from my place which is in one of the lowest areas in North Wollongong, to a sl!
!
!
ight rise meant a temperature difference of at least 3-4 degrees by the feel of it. A lot of the areas around Goulburn, Canberra, and from memory Bathurst as well is cleared so the effect of this cold air spilling into these city's would probably have some effect.

Anyway, I've started rambling on and I'm sure someone will have a far better explanation. If you ask me, 6 degrees today felt much, much colder than the windy, wet, and cold start we had to Tuesday morning when I also ran to work into the wind. That was cold enough.

Cheers,
Andrew Godsman

Katoomba's location on the top of the plateau doesn't really lend
itself to low minimum temperatures - under clear, calm conditions
cold air will tend to drain into valleys, whilst hilltop temperatures
more closely approximate those in the free atmosphere (this is 
particularly noticeable in the alpine regions - compare Crackenback
with Charlottes Pass and Perisher, for instance).

The Katoomba site itself is on the top of a high ridge with what looks,
from the photos, to be a pretty steep drop away to the west, so I'm
not surprised that its extreme minima are relatively high. The
Katoomba site has a very chequered history - it has remained in its
current (quite good) site since 1982, but before then it moved no fewer
than seven times in 20 years. I would expect that valley temperatures
in North Katoomba under last night's conditions would be anything from
4-8 degrees lower than those at the Bureau site, which would
take them down to between -2 and -6 (the Bureau site's minimum was
2). Katoomba isn't unique by any stretch of the imagination - Mt.
Boyce and Nullo Mountain also had minima above freezing last night.

Goulburn Airport can be a very cold site indeed. It's in open country
in a broad, flat valley and has a history of extreme minima, with
numerous readings below -10. It reached -14 in 1971.

Large town-airport contrasts are also quite common in cases where 
the town site has become affected by development in the vicinity
(bitumen car parks being a particularly common scourge in country
towns). Good examples of this are Glen Innes, Parkes and Walgett
(NSW), Naracoorte (SA) and Cunderdin and Southern Cross (WA).

Tony

The station at Katoomba is in Cliff Drive, about 0.5kmm south of the Great
Western Highway junction. It is on the highest part of the ridge, with the
land to the west dropping rapidly to the cliff line. As a result, it is
impervious to cold air pooling, and its wind and temperature will usually be
fairly close to the ambient conditions at about 900hPa (although the
Katoomba observer always seems to underreport windspeed). As a bushwalker, I
know that the best place to camp on a really cold night is the top of a
mountain!

Hi Andrew,

A very valid explanation I think.  Local topography on quite a small scale
strongly influences temps on calm clear nights, due to pooling of cold air.
Any sort of wind stirs things up and prevents the phenomenon.  I live on a
small ridge and have proven that temps between the ridge top and the bottom
of my driveway, which is close to a valley bottom, can vary by 4..5C on
still winter nights.  Vertical height is just 15m and horizontal distance
100m.

What it does mean is that minimums forecast & reported for places like
Ipswich are very misguiding for the average resident, because it all depends
on where you live.  It seems that Amberley temps are usually used in media
reports for Ipswich.  Amberley is just a few K's south west of Ipswich city
in flat open country.  It is not uncommon for Amberley min temps to be below
Toowoomba which is further inland and at 675m elevation cf 27m for Amberley.
Yet Ipswich city itself is generally quite hilly and I would suspect few
parts of Ipswich would have anything like the forecast and reported mins.  I
am not that far from Amberley (13kms NNW) and can have mins up to 8C warmer,
at a similar general elevation <50m but in hilly forested country.

General Whinge now follows....  It seems that Ipswich does have figures in
the BoM's climate averages (Ipswich composite whatever that means), and
these are somewhat different than those for Amberley.  E.g., July Av Min 5.5
for Amberley cf 6.9 for Ipswich and av number of days below 2 deg in July:
8.2 for Amberley cf 1.7 for Ipswich (and cf 6.2 for Toowoomba..!).

Which leads to the obvious question: Why does the BoM not provide more
representative figures for Ipswich to the media for public consumption?
After all, very few folks actually live at Amberley itself.

Maybe Blair can shed some light on that...

John.

Hi Tony,

It certainly was a cold start, there was even some frost in a couple of open
areas in Wollongong. We only got down to 6 degrees when I left to run to
work this morning at 5:20, so it was wrap up time.

If I was to have a guess as to why Katoomba doesn't get as cold as places
like Goulburn I'd say it is to do with topography. Katoomba and areas around
are on the tops of the ranges and would only really experience what the true
atmospheric temperatures are. This would probably be very different in the
deep valley floors, but I'm generalising here. The difference I feel with
places like Goulburn, Bathurst, etc is that they sit in lower parts of the
land as to what exists for a fair area round them and as such the colder air
has a far better chance of sinking into these areas and getting even colder.
My experience also, on a much smaller sclae is that with open grassland and
parks on the way to work, the air gets much colder around these and if this
air then spills into a hollow nearby, that hollow gets extremely cold
compared to the air around it. On nights like last night, a distance of
around 1.5km from my place which is in one of the lowest areas in North
Wollongong, to a sl!
!
!
ight rise meant a temperature difference of at least 3-4 degrees by the feel
of it. A lot of the areas around Goulburn, Canberra, and from memory
Bathurst as well is cleared so the effect of this cold air spilling into
these city's would probably have some effect.

Anyway, I've started rambling on and I'm sure someone will have a far better
explanation. If you ask me, 6 degrees today felt much, much colder than the
windy, wet, and cold start we had to Tuesday morning when I also ran to work
into the wind. That was cold enough.

Cheers,
Andrew Godsman

Interesting you should mention this - I was having a discussion 
about this on the weekend with an old acquaintance who's just been
elected as State MP for Ipswich, and who was similarly unimpressed about
what the Amberley temperatures do to Ipswich's image :-)

The Ipswich site was downgraded from synoptic to rainfall in
January 1994. I couldn't find the reason why in the files here but
presume it was financial (although the site wasn't great either). 

I don't think the Bureau would fund an Ipswich site itself, because
Amberley meets its requirements, but I imagine they would be 
interested if (say) the council was willing to fund an AWS, or
someone was willing to make a long-term commitment to observing.

Here in HK we have been paying HK$10.70 per litre for unleaded for 
several years.
Not sure of the exchange rate today but I think that's still over or 
around AUD$2.00 per litre.
People fit big tanks and drive to China (30Km from my home) to fill up at 
half price, but the import/export hassles on cars are just not worth it.

89.9c/L for ULP and 39.9c/L for LPG in Horsham atm. Think we would possibly
be the cheapest in Vic atm

Hi Blair,

The BoM climate data suggests that the last obs for Ipswich are 2001, i.e.,
current.  I wonder what this means...

The choice of site in Ipswich would be critical.  The city centre itself is
in a shallow basin on the banks of the Bremer R.  Not that the city centre
would be an ideal site anyway, but there is plenty of relatively open space
across the river  (river runs through a 20m deep ravine).  A more
representative location might be in the grounds of the hospital, which is on
a hillside to the South of the city centre, but probably not enough open
space for rain guage there.

I would be happy to commit to long term observing, but I am not at Ipswich
and Mt. Crosby would hardly be representative either, being some 11km from
Ipswich...

I think the council should give consideration to funding an AWS.  The Mayor
(John Nugent) is very gungho towards exploiting the area's tourist potential
and is actively encouraging anything which might help attract tourism.

Regards,
John.

Interesting you should mention this - I was having a discussion
about this on the weekend with an old acquaintance who's just been
elected as State MP for Ipswich, and who was similarly unimpressed about
what the Amberley temperatures do to Ipswich's image :-)

The Ipswich site was downgraded from synoptic to rainfall in
January 1994. I couldn't find the reason why in the files here but
presume it was financial (although the site wasn't great either).

I don't think the Bureau would fund an Ipswich site itself, because
Amberley meets its requirements, but I imagine they would be
interested if (say) the council was willing to fund an AWS, or
someone was willing to make a long-term commitment to observing.

Dear All

I have been avidly reading the e-mail and looking at the storm chaser
reports for a few months now. Love your work. This is my first ever
question question to you all and is for a friend of mine who is a keen
sailor on Sydney Harbour. He has asked me if there is a web site that shows
the current and predicted weather or satelite images for Sydney Harbour so
he knows where and when the best time to go sailing is. I presume he knows
enough about weather data to predict wind direction and speed.

Thanks very much for the forthcoming help.

G'day Tony,

Other folk have described the reasons for Katoomba's mild overnight temps so
I wont go over that ground, suffice to say, you can do some interesting
experiments in our area. I've been to the bottom of Mount Blackheath (I
think its called Centenial Glen?) and you can see some monster frosts in
that area. You can certanly find places in our area in cold pool setups with
much colder temps than the ridge tops. Interestingly, we get slightly cooler
minimums here than some parts of the ridge at my place as our home backs
onto a little valley. I sometimes stand on the back step and imagine what it
might take for that colder air to stir  just a touch and drop our temps a
fair bit. Still, it usually stays in the 2  to -2  range in my area and that
is common in winter. Even in this little valley behind us, the frosts can be
quite a lot thicker than our yard just one hundred metres from our house. In
winter, you can feel the change in the air as you walk down our quite steep
street, to the swampy area.

Well folks ther have been an interesting set of replies to this one.

The comments on the differences between the local topographies around the
Katoomba and Goulburn sites are valid, but do not provide the full answer, by
a long way.

This morning, as usual, the minimum temperature at our home site (-6.7) was
about a degree lower than that at the Bureau's site up the road at the
Taralga PO (-5). The difference in topography is the reason.

Goulburn's minimum temperature is usually a couple of degrees higher than
the Taralga PO site, simply because of the difference in altitude. The Taralga
site is at 880 metres, the Goulburn site is around 670 metres, I think. The
airport AWS a bit lower of course. It may be that the Goulburn AWS was in
error for once, of course, because the other Goulburn site at -4 is more in
line with that at Taralga PO.

If not, then those folks who have access to more detailed data might have a
look at the differences in dew points etc and pressure gradients between say
Goulburn and Charlottes Pass. There was only a degree difference between the
minima. If the conditions were the same in both places I would have expected a
-16 at Charlottes, simply because of the lapse rate with altitude. It seems to
me that a really cold pool went past Goulburn this morning

And, as I have said on another occasion, on each of the last
several nights under this present high, the Bureau's estimate of the o'night
minimum in Canberra, Cooma, Orange has been way too high. 4-6 degrees
difference is a big number. Please guys, don't lecture me again on the
differences in topography - the minima given by the models ought to reflect
the values measured at the Bureau's sites in the given locality. This is not a
criticism, I would merely like to know why it is that the models have
difficulty coping with still air, low humidity conditions.

Andrew of the same name, any comments?
John Gaul, the kind of weather pattern you were bored with back in early
May (blocking high) excites interest as an extreme weather event once we
get into frost-producing temps. BTW - looks like it was the best South Island
vintage on record!

I have two questions. One isn't weather related but may help out some what.
I got sent the following and wonder if it's true or not.
Guess what?  I was going through all my Windows files the
other day, and I stumbled upon a Trojan virus that my antivirus
didn't detect.  It's called "SULFNBK", and it goes by a lot of
different names, but it's a very destructive "macro-virus" that
will damage or delete a lot of Windows files to the point that
you will have to reinstall Windows.

There is a much easier way to check your system to see if you
picked it up somewhere than the way I found it.

Do this:

1.  Click the "Start" button.

2.  Click on "Find"

3.  Type in:  sulfnbk

4.  Where it says "Look In", select:  C:\WINDOWS

5.  Click "Find Now"

6.  If it's there, delete it to the "Recycle Bin"

7.  Now, delete it from the "Recycle Bin"

8.  Restart your computer.
--------------------
Secondly. This may be an obvious one but why does the temp always drop
sharply just about sunrise? I thought that the approaching sun would make
the temp rise and not fall. I start work at sunrise and it always feels
colder than well before sunrise.

Paul,

You're right in that local topography is only part of the answer, though
other things being equal, it is the most significant one. Altitude is only
part of the answer too -- Charlotte Pass (in a frost hollow at 1755m)
recorded -9.4 this morning, but Cooma Airport (in a frost hollow at 931M)
recorded -7.0. On a purely adiabatic basis you'd expect a difference of
around 8 degrees.

I think that the greatest differences can occur over very small timescales
and areas due to upper winds mixing down through an inversion that can
sometimes be very thin, and by movement or development of cloud cover and
local advection of moist air. Last winter I rode a bike from Dalgety to
Cooma. The ground was white with frost and I'd estimate the temperature
around -7 at Dalgety, with a clear sky and no wind. About 10km north, I rode
under a deck of stratus which appeared to be drifting in veeeeeery slowly
from the east. The air felt noticeably warmer and more humid, and I noticed
that the ground was moist not frozen, so I'd suspect an air temp of around
+3 or better. About 10km farther on, I rode back under clear skies, and
froze again. It underlined to me just how variable and hard to forecast
minimum temperatures are, as a whole range of micro variations can produce
major temperature fluctuations.

The models certainly can't cope with this short wavelength variation; even
with the best topographic database in the world, they won't pick the other
variations over small areas and timescales that can lead to substantial
variation.

1. sulfnbk.exe is a valid Microsoft file -- it manages long filenames. It is
the email currently circulating the world about it that is the hoax. I
checked this today, and though I've deleted the reference, you can read all
about it on Symantec's website.

2. Don't know about the temp dropping sharply at sunrise, but it does
continue to drop, as incoming radiation takes some time (~half an hour?) to
exceed outgoing radiation. Depending on where you're standing, the slight
air movements created as differential warming is set up by the rising sun
striking nearby surfaces could also drift colder patches of air in your
direction.

update every 10 minutes or so at
http://www.ozwind.com.au/newstuff/nsw02.php3
The BoM observations page for Sydney would also be useful
http://www.bom.gov.au/products/IDN65066.shtml
This page might also be useful
http://marlin.mhl.nsw.gov.au/htbin/wave_data_plot.com?Location=Sydney
and pressure trends over the past few days
http://marlin.mhl.nsw.gov.au/data/tide_data_baro.htmlx
You'll find the BoM forecast for Sydney closed waters here
http://www.bom.gov.au/cgi-bin/wrap_fwo.pl?IDF11N00.txt

Just a few things to start with .......

Hi Bussie,

I'm not sure what you mean by a 'sharp' drop before sunrise, as a sharp drop
would imply some type of front moved through (katabatic flow? - which can be
like clockwork). But more generally, the actual tempreture as related to
heating rates is out of phase. By that i mean that the strongest heating is
at 12 local noon but the highest temp is about 3pm - generally. This is the
same for night, except were talking about cooling. Once the solar radiaiton
becomes negligble (around sunset), the strongest cooling occurs because the
surface temps are the greatest and the outgoing longwave radiaition (OLR) is
very large. Hence, the surface cools and by sunrise, the coldest tempretures
are reached. This would not be sharp drop though but rather an exponential
decay. So this is probbaly not the answer to your observation. But it's
worth noting delatyed highs/lows as they are related to maximum
heating/cooling rates.

As a side dish, this is not restricted to the surface - the reason for
spring being the most explosive season is because the upper atmosphere is
still cold from winter but the lower atmosphere is just starting to warm -
it can take upto a couple months, depending on location, for the surface
warming to propagate up in the atmosphere and stabalise the atmosphere
(usually a nice summer). Conversly, Autumn is very calm because the upper
atmpshere is warm but now the lower atmosphere is cooling - which will in
turn propagate up and we start all over again.

Cheers, Lyle
