Laurier,

I think this very small change made a large difference in Wollongong this morning. Whereas it sounds like some areas had nights that were even colder than Thur morning, in Wollongong we were around 5 degrees warmer. It appeared that the bom had the minimum picked right when we were showing 11.7 at 9:30 last night, but on leaving home this morning at 5:30 it was still only 11.2. The only difference, an ever so slight SW breeze. I'm not sure if we got colder during the night, I'll need to check the minimum when I get home, but it certainly could have before the breeze moved things along.

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.

Hi Bussie
I've noticed the same occurring here on my farm around dawn, particularly in
winter, when out on the tractor.
As the sun rises from first light, the frost sets where prior there had been
none. It usually only lasts a short time here and is gone not long after the
sun actually rises above the surrounding tree line but remains where shaded
until the ambient air temp. rises enough to melt it!

Hi all.
Apart from being embarrassed by the trail of cows that follow me up the
Leopold hill when a photographic opportunity is in the wind, the big buggers
are now into pinching my raingauge off the rear fence post (my property
backs onto farm).Its odd though as the culprit is an elderly cow with warts
all over its mouth , (I always seem to attract this sought!) she simply
walks up to the raingauge, eyes it from one side,  puts her head under the
fence and knocks it off the  holding bracket,once on the ground she noses it
off in the direction of the open paddock with me in pursuit.  I kid you not.
Apart from moving the gauge this is the best spot of open ground,any cow
experts out there?.Any way I thought I would share my experience seeing very
little weather is happening and can this be logged up as a cow or gauge
chase?....Things look better next week though with  what seems to be a major
cyclonic phase moving into south-eastern Australia,  with some reasonable
chance of  snow later in the week across the Victorian High country and
Tasmania,  might even get into the Blue Mountains,some good rain across
Victoria too..... Regards Clyve Herbert.........I think Jimmy is the cow
expert...

The title doesnt sound good, but they did ! :)

I just spoke to Tim Marshall and he said Jimmy and David both saw
tornadoes north of Amarillo Texas on May 29 (the day a 3 supercells in a
line took off in NW Texas (the day the webcam link from an Amarillo cam
was posted). The storm north of Amarillo put down 4 tornadoes, the last
of which lasted 30 minutes.
Expect some great footage when they return !

The Dutch Storm Chase Team saw a tornado in a storm south of Amarillo on
the same day, and have posted some pictures of it here :

i have no explination to this but only a observation.
A few years ago i was travelling to sydney with a mate we were leaving at 6
in the morning. His car had a thermometer on it and when we left it was 10
degrees and still dark. around ten minutes later the first light of the sun
had spread across the sky and the temp had dropped to 5 degrees. i couldnt
explain then and i still can't now!! although i seen this happen again the
other night and i came up with a satisfactory explination BUT i forgotten
it. lol.....

We're looking at differences in scale here.

On scales of metres to a few kilometres, topography is critical, as
is local ground surface (for example, bitumen nearby favours high
minima, bare sand low minima). 

On larger scales (kilometres and tens of kilometres) other factors
become more important - such as cloud, wind, moisture levels and
the overall temperature in the air mass. This would go some way to
explaining the Charlottes Pass minimum above - I imagine there was
a little more wind or cloud than further north.

Small fluctuations in wind, which can explain differences in minimum
temperature BETWEEN sites, can also cause marked fluctuations at a
site, as any sort of wind will tend to break up the sharp near-ground
inversion that is characteristic of clear, calm nights (and which
is particularly pronounced over snow). It's not unknown for the
temperature at a site like Canberra to fluctuate 3-4 degrees from one
hour to the next during the night, as winds develop and then drop away
again (even 10 km/h can do this).

As for the forecasts, the models don't generate minimum temperatures
directly - they're based on a forecaster's interpretation of the
models. I'd noticed the recent overforecasting of the Canberra
minima too - and that the minima there in recent weeks have been,
in general, rather lower than what I would have expected myself for
the prevailing meteorological situation. I've seen this happen before
in prolonged dry periods (Canberra has only had 13mm in the last two
months), and expect that it is related to a lack of soil moisture and
consequent reduced moisture in the near-surface layer. Presumably 
this hasn't fed into the forecasting process yet - although the 
errors have been smaller in the last couple of nights.

I can't speak for Cooma and Orange, partly because I haven't been
following their forecasts as closely, and partly because I don't
know which site the forecasts are verified from (both centres have
a town and airport site, with significant systematic differences
between them).

Thank you to all who replied to my frost question. I now understand the
cold air pooling that occurs in valleys & why I will see very heavy
frost in the valley below my house, but Katoomba's minimum temperature
for that night would be reported as 3 degrees!
I have created a web site with Katoomba's daily maximum & minimum
temperatures, rainfall & snow days for the year 2000 & 2001 so far.
There is also a page on record snow falls in the Blue Mountains that
Lindsay from Blackheath gave me last year. Please check out the web site

You would need to take care that the rainfall is not being augmented by

Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

Very localised event in Sydney early this morningf with 97 mm at Little
Bay while less than 5 kms to the North there was only 3 mm The rain last
a while with 32 mm between 5 and 6 am, another 36 mm between 6 & 7 and
21 mm between 7 & 8 before easing off.
17 mm in 15 minutes fell in the royal Nat Park to the south in 15
minutes around 1.30 pm as well..... but virtually nothing anywhere else
in the state.
A look at the surface chart shows a high virtually on top of Sydney  but
as we know, that's only part of the story. 

Movement of upper high cloud over the continent continues. All the stuff
over the west 36 hours ago now over NSW then a big gap to another clump
around Broome and there's another mass about 750 kms WSW of Christmas
Island - one of these may eventually coincide with a front moving across
the SE stes to give the long needed rain in the inland.

hey people

I have just purchased an SLR and I am now looking for a scanner to go 
with it.

I was wondering if anyone could recommend a good one to buy. I dont 
want to spend too much, no more than $400. 

Should I go for one with one of those film scanner attachments, or will 
i get the results i'm after with just a normal flatbed??

My main purpose is to use the images on the web, so i'm guessing a 
super resolution is not a big concern, am i right??

feed back would be great

hey nick,
i have a standard flatbed, model canoscan fb 620p.
i have done my entire album with this thing. its perfect for just scanning
them for the web. i don't know what a film scanner attachment is:(
it cost somewhere around $200. scanners these days would be even cheaper.
if you spend 400, you would have a scanner with numerous other functions
that i can't think of.
this thing just plugs into the printer port, then ya printer connects to
the back of the scanner. just means if ya want to print you have to have
your scanner turned on.
all scanners can do different resolutions, zoom in etc
a flatbed is fine

They call it "One country, Two systems" and there is still an 
international border just up the road from here which you need passports 
to cross and anything, including cars, bikes, petrol, whatever that 
crosses has to be imported/exported from one region to the other.
We have the red flag with the yellow stars replacing the Union Jack and 
our post boxes changed from red ones with "EIIR" to green ones 
with "Hongkong Post" (which you can't find) but not much else has changed.

     Hi all in weather list land, and welcome to winter
         I was just wandering how badly people on this list find SDS to be, 
as no-one in the 'normal society' :) understands. Around this time of late 
autumn/late winter, is always a big struggle for me. I absolutely can't 
stand it. It feels kind of like being claustrophobic in a lift, only stuck 
in winter, no way (other than a ticket to Oklahoma, lucky bastards!), to 
escape.  Reading posts to this list and the aussie storm webpages I've found 
to be a good help.  I was watching the pretty sunset tonight going, yeah 
it's nice but phttt its 5pm and wheres the cumulonimbus on the ranges?. 
There are all these little things that trigger feelings, such as the smell 
of fireplaces, treading on heaps of duck shit going for a run, and all those 
posts from Lindsay (only joking Lindsay, i like your posts!), that are 
associated with winter.  I must say apart from ECL's and extremely cold 
outbreaks with an abundance of snow, i really hate winter.  So 3 months to 
go till spring, and with the thread of best storm locations being a good 
topic starter i though i'd try and start another one to get through winter, 
thus:
"Best location to see an oncoming supercell",
My unofficial top 5!
5: Mt Lofty overlooking Adelaide, with a sw'ly change aproaching. I've been 
up there 3 times but always in fine weather and with the whole city just 
down 'there' its a great spot

4: Standing on top of Ayers Rock. I was lucky enough to see an isolated 
storm from up there in '96 and it was an awesome sight, although i dont know 
of the chances of a supercell in that location.

3: The plains of Africa, with Mt Kilamanjaro in the background. O.K i'm a 
dreamer but i have thoughts of storms like this running through my head all 
the time !

2: In Oklahoma, the sun at your back, bright yellow corn feilds to your 
front, with a massive black tornadic system encroaching, with crisp, bright 
white outlines up high, boiling furiously, and lowerings+rotation galore.

1: The Spot, Glenorie. Am i being biased? Of course not!, absolutely the 
best place in the world to watch a storm from. :)

            Happy winter everyone, can't wait till spring!!,, Rune

Only problem with this site is if you get hit from the Western face, it can 
get very cold, I have been inside (yes inside) a thunderstorm while it 
passed overhead. Although this may sound great, it's not that good when 
there is lightning all around you and you don't know where it's going to 
hit. From a distance of say 20km a storm would look absolutely awesome, but 
you may find you won't be able to see the base of it, unless it's a fairly 
high based storm. Give it a go during one of our very rare thunderstorms 
one day, it gives you a new perspective to the storms. The city does get 
quite hazy down there too when there are storms about, so not good for 
getting pics of the city and storms together.

regards

Andrew

After my stuff up "hoax virus" I thought this may be appropriate. Plus there
isn't too much happening weather wise. That I know of anyway :-))
Subject: New virus warning

If you receive an e-mail with a subject line of "Badtimes,"  delete it
immediately WITHOUT reading it.  This is the most dangerous E-mail virus
yet!!!!!!

* It will re-write your hard drive.  Not only that, but it will scramble any
disks that are even close to your computer.

* It will recalibrate your refrigerator's coolness setting so all your ice
cream melts and your milk curdles.

* It will demagnetise the strips on all your credit cards, reprogram your
ATM access code, screw up the tracking on your VCR and use subspace field
harmonics to scratch any CDs you try to play.

* It will give your ex-boy/girlfriend (ex-husband/wife) your new phone
number.

* It will mix antifreeze into your fish tank.

* It will drink all your beer and leave its dirty socks on the coffee table
when there's company coming over.

* It will hide your car keys when you are late for work and interfere with
your car radio so that you hear only static while stuck in traffic.

* Badtimes will give you nightmares about circus midgets.

* It will replace your shampoo with Nair and your Nair with Rogaine, all
while dating your current boy/girlfriend (husband/wife) behind your back and
billing their hotel rendezvous to your Visa card.

* It will seduce your grandmother.  It does not matter if she is dead, such
is the power of Badtimes.  It reaches out beyond the grave to sully those
things we hold most dear.

* Badtimes will give you Dutch Elm disease.  It will leave the toilet seat
up and leave the hairdryer plugged in dangerously close to a full bathtub.

* It will not only remove the forbidden tags from your mattresses and
pillows, it will refill your skim milk with whole.  It is insidious and
subtle.  It is dangerous and terrifying to behold.

* It is also a rather interesting shade of mauve.

These are just a few signs.

Hi Rune & all,

The autumn stratocu season (normally lasting between 3 days & 6 weeks)
in Melbourne is my SDS season & this usually ends the day of the first
cold outbreak on or after 15th May.  This year's has been very short as
we have had a lot of AcCas & Cj turkeys about & the most wonderful
pyrocumulus (I must get the film developed), making for 'spring' skies
rather than autumn skies. Today we had middle level showers from
glaciated altostratus/altocumulus . . . . nothing SDS'ish about that!!

I spend a lot of my time between storm seasons (ie: late autumn /
winter) reading & reading & reading so that I'm 'more ready' for the
next season & catching up on all of the webpages, meeting minutes etc
etc that I wanted to do during storm season & didn't have time for . . .
. . have also started setting the car up for the next season (am I
starting too early???) - PS: MT - buy a CB!!


<snip>> "Best location to see an oncoming supercell",
> My unofficial top 5!

5. Mt Dandenong (looking NW - S)
4. West of Werribee on the flat country just west of Melbourne (360 deg
views)
3. Mt Ridley (in far nothern suburbs of Melbourne looking W - S - E)
2. Yarrawonga - flattish country - 360 degree views & a decent road
network
1. One Tree Hill - Ararat in the west of Victoria (360 deg views)

Hi Rune

Yeah SDS is hitting hard... Im keeping myself busy by looking at the US setup
every day. (Yes, before I look at the current oz situation ! :), reading chase
accounts, looking at photos of supercells in the states you saw the day before
on incredible close up visible satellite imagery that updates every 5 minutes,
and wondering what they looked like from ground level...then the SDS really sets
in.... If we *ever* get sat pics like that here either freely available or to
purchase from the BoM , it will be fantastic but I wont hold my breath waiting.
I think Australia needs to send up its own satellite :)

Top 6 - 6) The lookout at Bowral (shelter) 5) The lookout at Goulburn (shelter)
4) The lookout at Quirindi (shelter) 3) Rooty Hill (no shelter) 2) The lookout
at Gulgong  (no shelter) 1) The open plains 100-200km or so north and south of
Moree.

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.

Hi Rune & all,

The autumn stratocu season (normally lasting between 3 days & 6 weeks)
in Melbourne is my SDS season & this usually ends the day of the first
cold outbreak on or after 15th May.  This year's has been very short as
we have had a lot of AcCas & Cj turkeys about & the most wonderful
pyrocumulus (I must get the film developed), making for 'spring' skies
rather than autumn skies. Today we had middle level showers from
glaciated altostratus/altocumulus . . . . nothing SDS'ish about that!!

I spend a lot of my time between storm seasons (ie: late autumn /
winter) reading & reading & reading so that I'm 'more ready' for the
next season & catching up on all of the webpages, meeting minutes etc
etc that I wanted to do during storm season & didn't have time for . . .
. . have also started setting the car up for the next season (am I
starting too early???) - PS: MT - buy a CB!!


<snip>> "Best location to see an oncoming supercell",
> My unofficial top 5!

5. Mt Dandenong (looking NW - S)
4. West of Werribee on the flat country just west of Melbourne (360 deg
views)
3. Mt Ridley (in far nothern suburbs of Melbourne looking W - S - E)
2. Yarrawonga - flattish country - 360 degree views & a decent road
network
1. One Tree Hill - Ararat in the west of Victoria (360 deg views)

G'day Rune,

I can take a joke :) I can imagine how it must bore some of you guys
sh..less, this winter thing. Not so exciting for me at the moment either, as
this developing system looks like dying and giving mostly rain. Then again,
it will be great for the farmers.

Hi all

Prepare yourself for winter by going to my new SA snow page at:

http://www.cobweb.com.au/~paisley2/SnowWX.html

The lead story is a look at reports from 'The Advertiser' regarding the 2
[count em, 2] cold outbreaks of July 1951.  The second one, on the 20-21st
of July was truly extraordinary in many ways.  Anyway, there are MSL maps
to drool over and questions posed for commentary.

Maybe this will get the ball rolling with reports from the east regarding
this event.

Enjoy, and I'll appreciate your feedback.....

Phil

Well I mightn't know much about the weather, but I do know about these 2
products.  Not that I have used them both personally.  Not to worry, I don't
often get a chance to contribute something useful to the list .. <S>

Nair is a hair removal cream, whereas Rogaine is a cream that is used to
promote hair growth.  And I'm not even a yank ..  just a has been pharmacy

Hi everybody.
A moderate strength cold pool is advancing north-eastward from well south of
WA,also some reasonable baroclinic areas over much of the western half of
Australia. Look for vorticity around the western Aus Bight over the next 12
to 24 hours.

Hi phil,

Great article on the snow falls, although not a great fan of snow it's good 
to see you are keeping busy while the weather isn't :) I have added the 
link of your snow page to the article section on the SAStorms site.

By the way Phil, do you have the name of the guy who took the photograph of 
the Appila twister? I have looked high and low on my hard drive and cannot 
find the information.

Something else you may be interested in, I have requested information from 
the bureau of Met about the 22nd of Jan 1991 storms and also 8th of Dec, 
Snowtown supercell in 1999. I have also requested to get a copy of a 
tornado photograph that was taken on the 5th of May, THIS YEAR from south 
of Mt Gambier. Hopefully this information will fill the articles page a 
little more.

regards

Andrew

<br><b>Venue</b>: The Weather Company, 7 West St North Sydney.
<br><b>Time:</b> 7pm
<br><b>Parking</b>: Free in the streets around TWC building.

<p><b>Feature Presentation.</b>
<br>Although very quiet on the weather front in Australia , Jimmy Deguara
and David Croan have been roaming the Great Plains
<br>of America, storm chasing for the past month, and Jimmy (possibly David
as well) will be presenting video and analysis of
<br>there their recent trip. We know they managed to catch tornadoes from
supercells in NW Texas on May 29, BUT they seem
<br>to have been extremely secretive about their experiences over there,
not letting anyone know what has been happening.
<br>Expect some incredible thunderstorm footage and photographs of tornadoes,
storm structure, hail smashing the front
<br>windscreen (ok maybe not this one but who know's!) Did Jimmy manage
to see his aim of giant hailstones ? Did they come
<br>across large enough hail drifts that David was able to build a "Jimmy
Hailman" ? We will find out on the night!!!
<p>Please bring a couple of dollars for Pizza as well. This will certainly

Great site Phil obviously quite a bit of effort there.  Living in the south 
eastern suburbs I wouldn't mind some snow:)  Very interesting system 
developing this week with some significant falls of rain possible.  Finally 
starting to see moisture being pumped in from the NW hopefully some more NW 
cloudbands this year than last year.  Also mentioned on the weather zone 
list was the fact that a period of cradling highs, cradling lows in the 
Bight and southeastern Australia hasn't been seen for quite some time at 
this time of year.  Hopefully this could see some very decent falls 
developing this winter with another possible similar system developing over 
next weekend or early next week, a bit far off yet I know.  Wouldn't mind

Hi everyone,
                  I have received word that our intrepid storm chasers have
captured a couple of tornadoes in recent days while on the Oklahoma plains
(I only hope they can bring them home!).  No doubt we will hear more in days
to come..

Hi every1,

I agree with Matt Smith...the only way I cope with winter (except for 
tornadoes in northern Victoria - but nowhere near here) is to virtual 
chase....

Log on early...check the US radar summary...then check the visible 
satpix...then find a city close by and get on a weathercam!!!

Lotsa fun if you've got the time...which I don't anymore...:((

Cheers,
Kevin from Wycheproof.

I think a scanner's most important feature/asset is its colour tolerence.
Most scanners have the same resolution, and some are sharper than others,
but it comes down to how well they handle colour, and this affects how well
they handle dark photos, light photos and over exposed shots.

Most scanners that are $200 are pretty good. $400 will buy you a great
scanner. You might be able to afford a negative tray too (for the purist at
heart).

Hi all,

Jimmy had even sworn his mother to secrecy but it just made me more 
suspicious when she said that Jimmy hadn't even mentioned anything about 
storms when he called!! Jimmy not mention the weather/storms???

All who can make it should be at the Sydney meeting on 16th June when all 
will be revealed... that is the footage, photos, etc... not Jimmy and David!

Great report.
I remember the 1951 cold outbreak very well indeed.
I was a kid living in Terang, Victoria.
The night before the great snowfall, my mother read me a book about 
the "Little Match Girl" who died in the snow, and we discussed how Norway 
was a land of ice and snow.
When it was time to say my prayers, I prayed that God would send us 
enough snow that Dad could build a snowman before he went to work in the 
morning.  My Mum got awfully flustered about the prayer trying to shut me 
up because "it only snows in Norway, not here in Australia".
Next morning, the whole town was covered in inches of snow and Dad made 
us a snowman before he went to work.
According to the Terang Express, this was the first time since white 
settlement that snow had ever been recorded there, and as far as I know 
it has never been recorded again since.
So now the question arises:  did the prayer of a little boy who didn't 
know any better cause the great cold outbreak of 1951?

Tony,

I spend quite a bit of time at Goulburn Airport. As others have
mentioned it is a very open, flat spot but also the AWS is right at the
bottom of a gradual sort of hole, so ofcourse the cold air pools there.
The place is also very well known for regular and long-lasting fog -
quite ironic for an airport.

You'll notice that Gouldburn AWS (Airport) temps constrast alot with
Goulburn (PO I think) temps despite the fact that as the 'cessna' flies
they're about 2 miles apart.

Goulburn AWS is always the first station to go negative of a night in
fine weather condidtions.

Andrew.

The Goulburn town site is in P{rogress St - about 3.5 kms from the

The distance is actually 7.5km. The Progress Street site is on a ridgetop in
northeastern Goulburn, while the AWS is, as Andrew says, in a classic frost
hollow well south of the built-up area. The two sites almost seem chosen to
represent the two extremes that can occur due to topography on a cold night.
Bombala is similar, with the Post Office site just above the Bombala River
flats, and the AWS about 11km (I think) south of town on a substantial
mountain top.

Hi tropo's.
Check out the massive area of cloud west of Papua NG,  lots of embedded
CBs,although very poorly organised this region of cloud developed at the
north end of a major long wave mid lat trough a few days ago and has been
drifting westward very slowly. The only sign of organised upper flow is in
the northward moving outflow anvils over the eastern side of the cloud
mass.This area  is worth watching to see if there is any interaction with
the approaching long wave trough now advancing/stalling over the western
half  of Australia. regards Clyve H..

Hi Nick,

I have an EPSON GT-7000 USB scanner and have found it to be very good. I
also have a negative and slide film attachment for it so that I can scan
them.

Pretty impressive when the Australian Severe Weather Association (ASWA)
finds itself listed on the BoM website in amongst sites such as
universities, CSIRO, met services in various countries, WMO!!!!

This in the first 2 years...and so much more besides - interviews on
radio & TV, articles & displays, joint presentations with other
organisations.......!  What will ASWA achieve in the next 2 years?

I personally think we should concentrate our efforts on building a weather
controlling machine to get rid of SDS in Australia once and for all.

Imagine the publicity that would create.  "Lunatic weather watchers bring
tornado's and cricket ball hail to all capital cities in what is believed to
be an effort to bring Australia under their control."

Hi all..

In reply to Blair.
 i noticed the other night when i got home from work at 12:15am it was -1.9
and then when i went to bed at 4:00am it was 8.9degrees. i noticed the cloud
had rolled in and had the typical purple sheen to it that i see often in
canberra. Most probably from the city lights.

Simon Angell
Canberra ACT
current temp is 8.5 degrees...

Must agree about Gulgong, if only they would build a shelter there. A nice
piece of lawn and a tree in the centre would not go astray.

What lookout do you refer to at Bowral ?  Is it Mt Gibraltar.

I think that Razorback lookout at Picton is very good too, except you can
see right up north along the Blue Mountains, into Putty Road territory, I
get wanderlust everytime a see a nice cell up there. But my enthusiasm is
tempered by the knowledge of a mongrel drive through Sydney's west.

Simon, it arrived here in HK at 22:38 on 4/6/01 HKT (UTC +8:00).  I guess 
that means 00:38 on 5/6/01 in Eastern Australia.
This means it took 24 hours and 1 minute to get from your PC to my 
mailbox.
I think the problem lies with your ISP, as my posts always come back 
within 30 - 60 minutes.  Once in a while I see it only 2 or 3 minutes 
after posting, but that is rare. My mail server here only sends to and 
receives from the Internet once every 10 minutes  so that explains 
anything up to a 20 minute delay on seeing my own posts. Assuming the 
server at world.std.com has a similar setting, it would surprise me to 
see it become less than about 20 minutes.  I expect around 40 minutes to 
be the norm.

But where your post has been wandering for a whole day, I dunno!

Well, I'm sitting here in a short sleeved shirt as its 13 degrees! Quite
amazing for we folk in Blackheath. Maximums at my place so far for June are
9.5, 12, 13, 13 and even warmer at the Mt Boyce site. It usually gets warmer
there, than here, on sunny days. My temps compare well until mid-afternoon
on days like this, then the sun seems to push Mt Boyce AWS temps to 1 to 2
degrees above mine, as the site gets maximum afternoon sun. Curiously, on
overcast days, my site is almost always in agreeance with Mt Boyce.

Looks like it could get to 14C or more today. I have the back door open and
the sun is streaming in and it feels like March/April, not June. Even this
upcoming rain event looks mild and wet rather than cold or even cool.
Bummer. When will winter arrive?

Can't see anything drastic happening over the next week or two.

Cheers,

Ah well it just goes to show.  Here I am in Brisbane thinking that winter
had come early in mid May and wondering what on earth it was going to be
like by end of July.  Extrapolating from the last few weeks in May, I had
guessed severe frosts & even sleet was possible.  But the winds have finally
turned on shore again and hey presto - winter has taken a vacation.  Really
nice the last few days with temps in mid 20's, humidity back to an
acceptable 60% or so, and mins around 12-13C.

Funny thing though, similar event happened last year and the entire winter
ended up being mild after some fridgid dry weather in May.

If it was 13 in Sydney I think we'd call that pretty cold, but it's all to
do with acclimatisation I guess. Balmy in Sydney and about 17 at the moment
but anything under 20 and I'm more comfortable in longer 'woolies'. Warm in
the sun but cold in the shade.As for a mild change, I notice that even after
the predicted southwesterly goes through it's still expected to be 19 in
Sydney which is about 2 above normal. On a recent post I said something
about the high pressure systems tracking more northward but it was pretty
short lived and the next high is expected to settle over Victoria in a few
days..so more onshore 'stream' weather?

No..the one ASWA people use on Wednesday nights especially..(or used to be

Hi Keith,

It's not an ASWA (or affiliated) room - it's open to the general public,
and you can access it using any IRC software client (Pirch, mIRC etc),
and you can connect to the Austnet server (usually they have a list of
servers in the IRC client), but you can use the command 
/server au.austnet.org
to get you in.

The chat room is called #Weather (/join #Weather)

Sorry, I misunderstood.  I guess you must mean the ASWA committee chat
channel which you can log onto with mIRC, which you can download from

What can I say Lindsay.. I guess it depends on your definition. Any weather
beside sunny with a light wind is interesting in Melbourne at the moment. 

I am quietly optimistic that much of SE Australia will get a major rain
situation, but with the progs - well - looking so down-right weird one can't
be certain. One thing that has caught my eye with the approaching system is
the very high dew points which are starting to show up over much of
southern/central Australia - widely 11-15C. I doubt this system will be a
flooding event (the baroclinicity across the system is relatively modest),
but it looks like it could provide the first substantial rain over most of
Victoria and western NSW for 3+months. BTW, also noticed that the thickness
over northern South Australia are going to be marginal for snow/sleet on the
higher peak (thickness ~544gpdm) - pity "no" one will be there to observe
anything.

Hope I haven't jinxed it...


Cheers,

David.

Keith,

You can download mIRC from http://www.mirc.co.uk

I think the JAVA chat is on the Karratha Weather page, but I can't remember
the URL for that

Hi all

Well boy am I surprised.  I've just noticed it fairly dark to the
northwest, and checking the Melbourne local radar shows some precip coming
our way.  Although, it remains to be seen how much of this is actually
reaching the ground.  However, places to the northwest, like Bendigo, have
reported 1mm of rain.


Cheers

Yes, I should say that a significant rain event is fantastic for those that
need it. Its perhaps a bit selfish of me to be annoyed about the "Warm"
weather we are having early winter and the warmness of the approaching front
when much of south western NSW and Victoria etc, is desperate for rain.

I rebuke myself . Still, I do want some cold weather eventually.  :)

Hi all,

Must admit that I concur with the Brisbaneites on the recent weather.
Although it is currently (1600EST) a balmy 20 plus here in Proserpine, in
the last two weeks our recorded minimum has been as low as 4.6, and many
farmers report temps down to 3. Also had three (light) patchy frosts which I
consider a bit unusual, and the pasture shows the effects.

Not really looking forward to "winter" !!!

Bill,
in a mild, windy (25kn SE) and showery (11.5mm over 5 days) Proserpine -
where big highs down south usually mean showers up here.

Hi all!

As John pointed out earlier - it's been quite warm recently for winter. 
Past few days I've been registering max temps around 24-25C, at 11am at
work I was recording a temp of 25C - but it hovered around that all day
(assuming that the cool, moist E to SE'ly wind kept the temps down, as
well as some nice coastal CJ's).  

Yesterday there was some very nice TCU to the SSE of Toowoomba, and
today there were some convective showers over the ranges!  For those who
know about SE QLD's climate, it is 'famous' for it's horrible dry,
windy, cold (~20C max) days during winter, when highs push through
giving strong SW'lies.  This is them broken up by SE'lies that generally
keep max temps similar, but keep mins up).  Why are the maxes up with
the SE'lies though?  It really is a pseudo-E'ly, the winds are coming
along on a 1500km+ E'ly fetch across the Coral sea, and just dipping
into a trough a few hundred kilometres off the coast that is causing the
winds to come to us from the SE.  As this front and trough moves across
slowly, we'll get some NE'lies, and possibly even warmer mins and
maxes!  Depending on cloud, we could see some places knocking 27C in a
few days time.  Cloud will be the main factor, there is a chance we
could get bogged under mid to high cloud as a NW jet heads our way.  As
the jet strengthens in response to the cold pool pushing through, it
could produce a deeper cloud band.  This would be good for those down
south, but perhaps not so good for us SE QLD'ers.  Especially if we are
to have a chance of storms over the weekend, we won't want any cloud!

Interesting situation though - I knew that it would get warmer when I
went out and bought a replacement heater for an older heater that broke
down just over a week ago!

Meanwhile - this warm blooded Brisbanite is enjoying the warm
temperatures!  In particular the much 'friendlier' mins.

Yep... from Canberra's perspective even some clouds will be nice...

Have to say I am suffering WDS (weather deprivation syndrome) - it is like 
SDS but much more severe. I missed the last 1mm downpour by being in 
Melbourne at the time - despite (or because of) buying an umbrella, I 
managed to avoid any rain at all  :(

Lake George is not supposed to be a dust pan - it generally does have water 
in it... (with some exceptions I won't go into in this post)

The sad story is told here...

http://www.bom.gov.au/climate/current/rainfall_1month.shtml
http://www.bom.gov.au/climate/current/rainfall_3month.shtml

Hopefully the progged rainband looks like it is going to target the areas 
that need it most. My only concern is it doesn't fizz as it moves east.

A hopeful Patrick

Been bloody warm here too,

Yesterday breezed past 20 right up to almost 24!  That's gotta be something
that only happens a few times a century in June I suspect.  Today felt warm
too - certainly over 20.  Some nice congestus piling up now so it looks
like we are in for a dump, although a decent cold snap still seems a remote
event.

Hi Anthony,

There have indeed been some nice TCu around, particularly last Friday when I
spotted a very nice mid level cone shaped funnel and long thin "rope".
Regrettably I was in a colleagues car careering down the Western Freeway
with no camera to hand. :(

Lindsay,

I think Wednesday and Thursday will be noticably mild too. The forecast
thickness values on the models are quite high, dipping down from the
north as they do in summer. Depending on the humidity and the amount of
rain we get, it could be decidedly muggy - not what people like us are
interested in June!

Andrew.

Hi all,

According to Rob Gel on CH9 weather tonight, the maximum temp of 20.9C in
Melbourne was the warmest June day since 1957.

Some of the climo's out there might be able to confirm this one.

Regards,

Andrew McDonald

Anthony

I agree almost warm and balmy today in SEQ. But the law of averages tends to
suggest that things will correct things soon. After a bit of a warm spell,
there is usually an equally aggressive cold spell to even things up. However
I can't quite see it happening just yet.(I'm still think a genuine ECL is
not too far off, followed by a genuine cold outbreak -  time will tell)


Regards
Simon

Hi every1,

I'm starting to get VERRY nervous about my websites as they're all "free" 
servers. In recent weeks, most have been down for quite extended periods and 
some won't accept any uploads at all. In the last month I've had to remove 
all of my storage data from "free" servers and now the provider for may main 
webpage is "undergoing exteneded maintenance".

I'm certainly not whingeing about getting space for nothing but feel it only 
prudent to tell people that I suspect that many free servers are in the act 
of folding and may well lose all data therein...

I hope I'm just being my usual pessimistic self, but I'm sure there are many 
on the list who use these providers and wondered if anybody else has had 
these problems?

SDS = Storm Deprivation Syndrome. A condition whereby the sufferer thinks 
that fog is the chase coming to them.

Macca: 20.9 sounds low even for Melbourne in June.

Cheers,
Kevin from Wycheproof.

Could our higher than normal ground temps combined with a bit of moisture

Hi Robert.
You may have noticed how the developing 'lee wave' today south of the divide
increased in density as what appears to have been  a passage of a short wave
mid level trough this afternoon. It was interesting to see the progressive
thickening of this mid level cloud prior to 1400hrs and then to see most of
this mid level development undergo glaciation.I got 12mm here at Leopold,
looking good for the next few days... regards Clyve H.

Hi all.
One would have to be forgiven if your interpretation of the sat pic for the
Australian region especially the fringing tropics as being closer to summer
than June, but has anybody noticed (apart from the very nice and active semi
cut off over SA) the huge amount of tropical moisture lurking north of a mid
latitude long wave trough west of Australia. A similar tropical moisture
plume has been affecting the central Pacific for the past two weeks, worth
keeping a close look..regards Clyve Herbert.

Hi Phil.
In May 1979 I was running  the 0100 Geelong to  Warrnambool overnight goods
(midnight horror as it was known).The forecast was for a colder southwest
change reaching Melbourne in the early hours, I think it was the 31st of May
(set me right please Blair).After grinding all the way from Geelong to
Camperdown with a less than healthy 1952 vintage B class diesel loco,steady
rain with northwest winds (gale force) gave way to hail and then snow.We
staggered into Camperdown for a shunt in blinding hail and snow,also snow
pellets and the ground very white,by this time about 0430hrs the wind had
shifted to the south west and the temp was about 0c. However the best was
yet to come after leaving Camperdown our train entered a rare and unusual
landscape with what I can only describe as near blizzard conditions and
waves of heavy snow showers and in places the snow was blowing along like
sea spray. We arrived at Terang about 0500hrs and shunted the yard with so
much snow on the ground you couldn't see the top of the rails,after leaving
Terang the snow petered out and rapidly became thinner on the ground
approaching Garvoc,with no more snow after that.. I loved it. regards Clyve
Herbert.

Anyone care to tell us what's happening in Adelaide at the moment? The

with the Woomera radar which has gone absolutely crazy!

Heavy rain started here in Adelaide soon after 9pm.
Just a couple of rumbles here and there.
At Newton we have had 15mm in the 3 hrs since, Kent Town 17mm.
Roxby Downs/Olympic Dam probably the pick at this stage with over 30mm
since 9pm from those storms on Woomera radar. (all those lovely
colours!!)

Tim.

The spectacular radar seems to be for real, though I think some of the pink
stuff could be raised dust -- Woomera was reporting 33km/h wind gusting
44km/h at 11.30pm. Roxby Downs had 27.8mm between 10pm and midnight, and
many other falls in the 10 to 30mm range between 6pm and midnight across the
western 3/4 of the state. An enormous area of yellow and pink has entered
the top of the Adelaide broadscale radar and should be arriving in Port
Augusta around now (1am EST) -- if it maintains intensity and keeps on its
current trajectory, Adelaide could have an interesting time around dawn.

Something interesting may have happened at Coober Pedy -- the AWS reports in
the past few hours are:

The missing ob for 2300, followed by loss of rainfall data is interesting,
suggesting a power outage. Meanwhile, Woomera has also lost its rain obs:

1230 20010605 2230  30/ 14  18   15.2  13.8 1012.2 |  5.4   0.0   0.0   0.0

30  | 9.0*

Farther south, Minlaton has had 19.8mm since 8pm, Edithburgh 15.2 mostly
since 9pm, Parafield and Edinburgh RAAF both 16.6 since 9.30, the Bureau at
Kent Town 16mm since 9pm -- all totals to midnight. The rain map since 9am
for Adelaide at http://www.bom.gov.au/hydro/flood/sa/sa_metro.shtml is worth
a look, as is the rain map since 9am for all SA at
http://www.bom.gov.au/hydro/flood/sa/index.shtml, although it's a bit far
between gauges.

I also have a Canon 620 and I like its small light weight. I note that it
does not scan matt photos or magazine articles as well as the glossy
pictures, nor as well as a previous scanner. However if photos is the only
use , yes I would recommend.

The whole issue of slide/film attachments is a minefield. If inbuilt to a
cheap scanner they are not very effective.

A proper film scanner starts at $800 and goes up from there. You would not
believe how tricky film scanning negatives is. Slides scan OK as across
brand like Fuji, Koda, Kodak, etc a slide is the finished product and
colours are final. However negative film varies slightly from brand to
brand. The process lab actually treats each film brand slightly different to
each other when developing prints. When you scan negatives you yourself have
to make the colour adjustments and I have heard this can be tricky.

One final point - I now actually think digital cameras have come to a point
that for web photos they are superior. Colour saturation with most modern
ones is excellent. I would serious look at a digital. For magazine work and
posters the traditional film is still in front.

It must have looked spectacular crossing the trestle near Boorcan.

Well, I shall have to amend my story for all future tellings.

I remember the midnight horror like an old friend - when I was a little 
kid (primary school days) I would head off down to the station around 
04:40 every morning, as most of the drivers would let me ride on the 
footplate while shunting was going on.  I used to love the big A2 class 
engines the best.  Later they were replaced by the J class.
Shortly after the midnight horror left Terang the "Paper Train" (express 
goods - loco, two or three vans and a guard's van) would come through.  
Sometimes the midnight horror would be late and the Paper Train would fly 
through first.
I'm well off the topic of weather now, so I'd better stop rambling on!
Thanks Clive for bringing back the memories...

Not impossible, depending on which day you were looking at.

There have been 24 days of 20 or above in the 147-year Melbourne 
record, and 7 of 21 or above. 7 of the 24 20+ days (including 5 of the
7 21+ days, and the June record of 22.4 on the 2nd) were the seven
successive days 2-8 June 1957. 

There are three very clear standouts for June-July warm spells in
southeastern Australia; early June, 1957, early July, 1994, 
and late July, 1975. 2001 isn't quite in that league, but it's still
probably a once-a-decade event.

A particularly interesting aspect of the 1957 spell (carrying on from
May) was the consistent occurrence of very large diurnal ranges in
Canberra (something we've seen to a lesser extent in the last few
weeks). The 2-8 June week saw records set, both of which still stand
(as of 1030 this morning!), for Canberra's highest June maximum and
lowest minimum. This followed a May with a mean minimum of -2.7, the
second-lowest on record for any month and 5.8 degrees below normal.

Hi Blair,

If GASP is to be believed the current mild spell for SE QLD will continue
for at least another week, with Highs staying well south and a ridge north
of NZ.

Meanwhile the folks in Perth are freezing with close to record mins...

Balmy or Barmy us that???

I am creating a Cloud Indentification Chart for Australia. I have one from 
ages ago but it was made in the USA so the directions and winds stuff is 
wrong for the Southern Hemisphere. So I am creating one for Australia.

It will be distributed under the GNU Documentation Liscense - 
http://www.gnu.org/copyleft/fdl.html

I am looking for images of all types of clouds from cirrus to cumulonumbus 
and wall clouds,etc. Small thumbnail images will be used in a table on the 
chart with a small description underneath. If you have any images you would 
like me to include, please read the above liscense. This liscense would allow 
any group to reproduce copies of the document, or even charge for them as 
long as the liscense is passed along with it. The GNU FDL will be on the back 
of the page. It will be an A3 size sheet of paper. All images used will have 
to have permission to be used under the FDL. Only a thumbnail will be used 
however, so your full-size image is safe.

I think this will be a good way for people to learn a bit more about weather.

Thanks, 

David

This sounds like 1977, not 1979 - there was certainly an exceptional
cold outbreak on 31 May 1977 (probably slightly ahead of 27-28 May
2000 as the outstanding May cold outbreak of the last 100 years).

Interesting,

I was at the beach earlier and could see a beautiful 'trail' of sunlit
congestus anchored over the Yorke peninsula - but in this northerly there's
no way it was going to head over Adelaide!

A very strange day here so far, mild [19 degrees] under heavy mid level
cloud with faster moving lower level scud.  Some evidence of wave
formations in the mid levels.  After last night's quite heavy rain [a few
rumbles of thunder but nothing else] hardly a drop today.

Phil

I didn't know there was anything all that special about May 27/28 last
year! It didn't seem in the exceptional category to me - we barely even
saw any snow on my part of the Southern Tablelands apart from a few
showers.

It was a little bit interesting because of the cold pool that brought
brief snow to Canberra and other places as it moved north but that's not
as nearly as 'exceptional' as alot of other stories from last century.

Phil,

Radar showed a nice line of pinks on the Yorke Peninsula for about an hour
this afternoon.

Radar to your N is just starting to look interesting.

(perhaps more luck on my part than anything though)

Regards,

Andrew McDonald

G'day Andrew,

It certainly was pretty exceptional for May, if  I understand it. The snow
we had here was fantastic! Sure, not a massive dump (around 8 to 10cm) but I
think I recorded snow over four straight days in that outbreak and Oberon
(to the south) had over 40cm  in that outbreak, too. Oberon had a day where
its temp range was -3 to -1 or thereabouts and that day saw -2.5 as a min
and 0.8 as a max at my place, so it was pretty decent up our way. Also, the
extent of the outbreak was pretty far reaching too.

Mind you, locals have told me that if you go back to the 50's and 60's there
were plenty of times the falls were better than the year 2000, as a whole.
Especially July (around 18/19th) of 1965, I think. 40cm here in the upper
mountains, they say, and numerous times to compare reasonably well to that
during these decades as well.

Anyway, Huey, give us snowies some cold! I might have to move to Fairbanks,
Alaska. :(

Hi Blair et al,

I distinctly remember the May 31, 1977 cold outbreak...I was in my Year 11 
Geography class in Bendigo when everyone went to the window (on the second 
floor of Bendigo High School) and wondered what the hell the funny flakes 
were! First (and only) time I've ever seen snow!

Never settled however...melted as it hit the ground.

Cheers,
Kevin (now) from Wycheproof.

P.S. 10 mm. till 10.20 p.m. today.

Hey all,

Just a quick note...rainfalls between Midnight Tuesday night and Midnight
Wednesday night were 18mm.

This brings the total to 26mm so far, which should give farmers around here
some hope of planting crops soon. Lets just hope we get another 20mm...that
should make most happy :o) Also put some much needed water in our storages
*Fingers crossed*

Hi all,

Just a quick summary of rainfalls I have had in the last couple of  days.
Tuesday we had 19mm
Wednesday we had 26.2mm (in 1 hour)
and in the gauge right now I have 3mm (since midnight)

Not a bad drop!

Rainfalls taken from a Nylex 1000 Rain Gauge.
Observations taken from Paralowie SA.

Hi all

For all us QLDer's that have SDS BIG TIME, there seems to be some small
relief on the way. But it looks as it will not have a significant affect on
coastal areas at the moment as it is forecast to stay South QLD and weaken
on Sat.

If last nights TWC lightning tracker is anything to go by, it will be a
great system as that band of lightning had us QLDer's drooling and wishing
we were out there. And never mind about trying to see anything on radar, cos
there is none.

I am interested to see what affect it will have on SE QLD later tomorrow and
Sat. Will it l9ive up to expectations?

Here's the QLD extended outlook

Hopefully, BRING IT ON ( i just want some lightning photos)

IDF00Q01
BUREAU OF METEOROLOGY
Queensland Region
Brisbane Office


QUEENSLAND WEATHER FORECAST
Issued at 4:45am on Thursday the 7th of June 2001
IDF20Q00
EXTENDED OUTLOOK
The firm coastal ridge will relax on Friday, particularly along the southern
coast, as the Tasman Sea high moves eastwards and is replaced by frontal
activity over the weekend. In the meantime moist onshore winds will continue
to
bring scattered to isolated showers onto the east coast and adjacent inland.
The
deep low pressure system over the Great Australian Bight will be slow moving
today then begin to decay from Friday. The band of rain and scattered
thunderstorms linked to the low will move slowly eastwards across the
southern
and central interior during today and Friday before weakening over
south-east
parts of the State on Saturday. Some moderate falls of rain are likely in
the
south due to the slow nature of its movement. It should be cloudy over the
tropical interior again today with possible isolated showers. Overnight
temperatures will remain well average due to the moist airmass and cloud
cover.
Daytime temperatures will be also be mostly above average but will fall well
below average when thick cloud cover dominates. In the longer term, a new
high
will move into the Tasman Sea on Sunday with showers limited to the
northeast
tropical coast only and fine weather over the rest of the state. Another
rain
band is likely to form over Central Australia during Sunday and we may see
the
eastern limit of this rain move into far western Queensland on Tuesday.

I have seen photos somewhere of a non-TT tornado that picked up a cow. Also I 
have seen a video somewhere of a Tornado that seemed to disapate without 
going all that much ropy.

very nice.

Amazing what a tight centre it has.  Would be interesting to be at ground
zero at that point.  You would surely have to see clouds out to the horizon
slowly circulating around you.

The overnight minimum was 17.4; the 24-hour minimum was 16.1 (the
0900 reset value from yesterday). Both are records by substantial
margins; the previous 24-hour record was 14.8 on 8 June 1995, whilst
the previous overnight record was 15.something (can't remember 
exactly but I think it was 15.5) on the same day.

It's the sixth monthly high minimum record to be broken or equalled
in Melbourne in my seven years here:

January		1997
June		1995, then 2001
September	1999
December	1994, equalled in 1998

<P>I am intrigued by some of the radar images I saw yesterday (or was it the day before?) of storms over northern south Australia.&nbsp; Unfortunately I don't have the ability to save the image or the loop, but I think Laurier may have referred to it in one of his posts.&nbsp; Since I have been following the radar, with its various shades of green, pink and red, I have never seen so much red and pink in one area.&nbsp; Laurier speculated that it may have been due to dust storms&nbsp; However the radar image I saw had red and pink virtually covering Lake Torrens.&nbsp; Who knows it may have been a salt storm!?<BR><BR></P></DIV>

<DIV></DIV>&gt; &gt; &gt; Hi everyone, Just a quick email to see what other people think 
<DIV></DIV>&gt; &gt; &gt;about the potential for severe storms in SA this arvo (more specifically 
<DIV></DIV>&gt; &gt; &gt;the Yorke Peninsula and Adelaide area). Shear is fairly nice 
<DIV></DIV>&gt;(actually - 
<DIV></DIV>&gt; &gt; &gt;pretty awesome - see below) and I have no doubt about the instability in 
<DIV></DIV>&gt; &gt; &gt;the area after yesterday and looking at today's sat pics and surface 
<DIV></DIV>&gt; &gt; &gt;obs. WV shows a nice dry slot sliding over the trough (currently looks 
<DIV></DIV>&gt; &gt; &gt;to be on the W side of the Spencer Gulf and as it moves across the gulf 
<DIV></DIV>&gt; &gt; &gt;it should pick up some extra moisture too. Maybe something to keep an 
<DIV></DIV>&gt; &gt; &gt;eye on. Also of note is the Ceduna radar. The centre of the low can 
<DIV></DIV>&gt;be 
<DIV></DIV>&gt; &gt; &gt;seen quite clearly on it. Anyway. Let's hope this lot drifts over Vic 
<DIV></DIV>&gt; &gt; &gt;as rain (with the odd storm thrown in as well). BTW - the shear over 
<DIV></DIV>&gt;the 
<DIV></DIV>&gt; &gt; &gt;above mentioned part of SA..... WIND: 
<DIV></DIV>&gt; &gt; &gt; 2000 5000 7000 10000 14000 
<DIV></DIV>&gt; &gt; &gt;18500 (ft a.s.l.) 
<DIV></DIV>&gt; &gt; &gt; 020/35 010/30 360/30 360/35 MS01 350/40 MS08 350/50 MS18 
<DIV></DIV>&gt; &gt; &gt; (direction/speed in knts) (MS01= -1C) Regards, Andrew McDonald 
<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt; Interesting, 
<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt; I was at the beach earlier and could see a beautiful 'trail' of sunlit 
<DIV></DIV>&gt; &gt; congestus anchored over the Yorke peninsula - but in this northerly 
<DIV></DIV>&gt;there's 
<DIV></DIV>&gt; &gt; no way it was going to head over Adelaide! 
<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt; A very strange day here so far, mild [19 degrees] under heavy mid level 
<DIV></DIV>&gt; &gt; cloud with faster moving lower level scud. Some evidence of wave 
<DIV></DIV>&gt; &gt; formations in the mid levels. After last night's quite heavy rain [a few 
<DIV></DIV>&gt; &gt; rumbles of thunder but nothing else] hardly a drop today.

BoM used to have a radar at Cobar years ago.  Took it out because it
was under used apparently, and put it somewhere else, up north if I
remember correctly.  Bet they are wishing they had one there now, or
even better, how about putting one at Birdsville to fill in the "radar
hole" at the state corners.

 Seems like a mean and cold southerly outbreak has been lashing a certain
area of Australia over the last few days. But I doubt that anyone on this
mailing list lives in the Eucla SE WA area of the Nullarbor. Then again I
believe hardly anyone at all lives in that area at all - I passed through
the region last year, and I remember about one roadhouse every 100 or 200
km. So some very interesting weather is probably going unnoticed - I heard
the recent forecasts were for thunder, hail, and severe squalls in the
Eucla. I don't think any land there rises more than about 100 metres, plus
the latitude is closer to the equator than Adelaide - snow is most probably
out the question.
 Another cold southerly change here in Christchurch, but a pretty weak one
at that - no rain here yet, but showers visible (on the radar) not too far
away. A beefier, (but relatively brief) outbreak is forecast is predicted
for the weekend.

If it's zero degrees outside today and it's supposed to be twice as cold
tomorrow, how cold is it going to be?

Hello All,

Wow.

Notice the cloud band shearing over Victoria atm, part of what was the
inflow to the low west of Mt Gambier is now being dragged away to the SE
by the subtropical jet.
http://207.133.112.37/cgi-bin/show.pl?sat+aust+wv+auwv20011581024.jpg
Pretty obvious why the low's starting to weaken!! but keep your eyes on
the area to the west of WA - that area of cloud & lower pressure in the
Indian Ocean off the Geraldton area has been almost stationary for the
best part of a week........and there's some very cold air coming up
behind it.

  <P>I am intrigued by some of the radar images I saw yesterday (or was it the 
  day before?) of storms over northern south Australia.&nbsp; Unfortunately I 
  don't have the ability to save the image or the loop, but I think Laurier may 
  have referred to it in one of his posts.&nbsp; Since I have been following the 
  radar, with its various shades of green, pink and red, I have never seen so 
  much red and pink in one area.&nbsp; Laurier speculated that it may have been 
  due to dust storms&nbsp; However the radar image I saw had red and pink 
  virtually covering Lake Torrens.&nbsp; Who knows it may have been a salt 
  storm!?<BR><BR></P></DIV>

  <DIV></DIV>&gt; &gt; &gt; Hi everyone, Just a quick email to see what other 
  people think 
  <DIV></DIV>&gt; &gt; &gt;about the potential for severe storms in SA this arvo 
  (more specifically 
  <DIV></DIV>&gt; &gt; &gt;the Yorke Peninsula and Adelaide area). Shear is 
  fairly nice 
  <DIV></DIV>&gt;(actually - 
  <DIV></DIV>&gt; &gt; &gt;pretty awesome - see below) and I have no doubt about 
  the instability in 
  <DIV></DIV>&gt; &gt; &gt;the area after yesterday and looking at today's sat 
  pics and surface 
  <DIV></DIV>&gt; &gt; &gt;obs. WV shows a nice dry slot sliding over the trough 
  (currently looks 
  <DIV></DIV>&gt; &gt; &gt;to be on the W side of the Spencer Gulf and as it 
  moves across the gulf 
  <DIV></DIV>&gt; &gt; &gt;it should pick up some extra moisture too. Maybe 
  something to keep an 
  <DIV></DIV>&gt; &gt; &gt;eye on. Also of note is the Ceduna radar. The centre 
  of the low can 
  <DIV></DIV>&gt;be 
  <DIV></DIV>&gt; &gt; &gt;seen quite clearly on it. Anyway. Let's hope this lot 
  drifts over Vic 
  <DIV></DIV>&gt; &gt; &gt;as rain (with the odd storm thrown in as well). BTW - 
  the shear over 
  <DIV></DIV>&gt;the 
  <DIV></DIV>&gt; &gt; &gt;above mentioned part of SA..... WIND:

  <DIV></DIV>&gt; &gt; 
  <DIV></DIV>&gt; &gt; 
  <DIV></DIV>&gt; &gt; Interesting, 
  <DIV></DIV>&gt; &gt; 
  <DIV></DIV>&gt; &gt; I was at the beach earlier and could see a beautiful 
  'trail' of sunlit 
  <DIV></DIV>&gt; &gt; congestus anchored over the Yorke peninsula - but in this 
  northerly 
  <DIV></DIV>&gt;there's 
  <DIV></DIV>&gt; &gt; no way it was going to head over Adelaide! 
  <DIV></DIV>&gt; &gt; 
  <DIV></DIV>&gt; &gt; A very strange day here so far, mild [19 degrees] under 
  heavy mid level 
  <DIV></DIV>&gt; &gt; cloud with faster moving lower level scud. Some evidence 
  of wave 
  <DIV></DIV>&gt; &gt; formations in the mid levels. After last night's quite 
  heavy rain [a few 
  <DIV></DIV>&gt; &gt; rumbles of thunder but nothing else] hardly a drop today.

<DIV><FONT color=#000000 face=Arial size=2>It's interesting that t the moment 
there is a split westerly flow ie the flow being caused by these cut off lows in 
the Bight, then the high cradling them, then the main westerly flow in the 
Southern Ocean. There was a similar pattern last winter (?August) except that it 
was in the southern Tasman with a high parked at latitude 50-55 and low 
pressures being forced to divert around it. Also last winter there was a massive 
anticyclone over the Falkland Islands (lat 55-60 or so) which reached 1052 Mb.So 
we are having the mild winter the BoM was expecting in its temperature outlooks. 
17 degrees in Sydney at the moment..almost a late summer reading for this time

My guess would be under 100 metres, certainly under 200.  Going from 
Terang down to the beach at Warrnambool when we were kids, there didn't 
seem to be too much difference in level.
The whole of that part of Western Victoria is one vast lava plain 
punctuated by frequent extinct volcanoes.  It's best described as 
a "rolling plain" - constant gentle ups and downs as you travel across it 
but no real hills apart from the extinct volcanoes.

Hi Phil,

Amazing how many "extinct" volcanoes there are, SE QLD is littered with them
too (the Glasshouse Mtns being obvious examples), but others are not so
obvious (Mt. Coot-tha & Mt. Gravatt I believe).  Reminds me a bit of Aukland
although not so obvious and not so potentially active.

Curiously, I read somewhere recently that Mt. Warning (by far and away the
most impressive extinct volcano in the region) has recently been upgraded
from Extinct to merely Dormant....

Michael Bath, did you know that??

My guess would be under 100 metres, certainly under 200.  Going from
Terang down to the beach at Warrnambool when we were kids, there didn't
seem to be too much difference in level.
The whole of that part of Western Victoria is one vast lava plain
punctuated by frequent extinct volcanoes.  It's best described as
a "rolling plain" - constant gentle ups and downs as you travel across it
but no real hills apart from the extinct volcanoes.

Well, this is easy. It is -1 as this is always used in mathematics if the
answer is unknown. It is also the dollar value of current One Tel shares.

Mmm.

Maybe the square root of -1 you mean, which also reflects One.Tel quite well
(well rooted in fact)...

The overnight storms in SA's central north produced record June rainfall
totals for Woomera and Whyalla. The Whyalla record goes back 94 years, so
that's pretty significant. Eucla also copped heavy showers overnight in the
cloudband wrapping around the low, and broke its June record of 88 years,
too. I've put a report and some interesting pix at
http:www.australianweathernews.com.

Hey,

Well 0 degrees is 32º F  Half of that is 16ºF  Which is -8.88ºC... HAHA

That was easy.  But i guess they dont work it out that way.

G'day Steve,

It's a long way out but around next Wednesday GASP and NoGaps seem to have
some moderately cold air moving into the south east. MRF sort of supports
this, well its not as cold but at least its heading in the right direction
and I've just had a look at AVN via the Unisys site and it supports cool to
cold air moving through as well although the timing of it all is in
question. Some of the models have a low in the Tasman supporting a high
ridging somewhat to the south which might help change the current warm
situation. Anyway, early next week might tell us more and also those that
know the models much better than me may comment by then, too.

Cheers,

I notice the Highs are further south than normal so far this winter. Hense
the extremes of heat and cold
in both Australia and New Zealand.  We had the coldest late May weather in
NZ with the snow to sealevel south
of Lat 45. Overnight lows in Melbourne of 16C in June is crazy stuff. This
trend looks to continue for a while yet.

Hi Andrew,

Ignore my first post about this outbreak as its a day old and was accidently
sent this morning.Yesterday, I was using another isp and forgot I couldn't
send the post from there, it was rejected and I then forgot to delete it
from my outbox.

Hope things turn out for a good outbreak although it looks like I have an
engagment I can't get out of next weekend, so from my point of view, make it
later saturday or sunday :)

It just takes a well-defined scientific experiment to find out:
At 0C my teeth chatter at about 5 cps (clicks per second) so I suppose 
twice as cold is whatever temperature increases the teeth clatter rate to 
10 cps.
But here in Hong Kong in Summer time it is a bit hard to figure out how 
to do the experiment.
Additionally, the fact that I wear dentures might affect the formula in 
some way.

Our fourth day in a row of almost continuous lightning and thunder here 
for all you SDS sufferers.  Yesterday all schools were closed because a 
Red Rainstorm Warning was hoisted.  At one stage yesterday the HKO had 
Four warnings at once: Yellow Rainstorm, Thunderstorm, Landslip, and 
Flooding.

Andrew, the May 27/28 event last year was extraordinary, especially for so
early in the season. Canberra was not particularly affected, but snow was
reported as low down as Gundagai (250m), with substantial falls on the
Southwest Slopes and Central Tablelands, isolating Bathurst, Orange and many
other towns. In Victoria, snow was widespread above the 200m mark.
Beechworth had 30cm on the ground. There are full reports at
http://www.australianweathernews.com/news/2000/05/20000527.html and

The legend states that a bunch of storm chasers descended on the town in
Spring 1999 in search of storms (of which they did not find, but created one
of their own!). The owner of 1 of 2 motels in town charged rediculous prices
for accomodation, so the chasers seeked accomodation in some rooms behind  the
only pub in town. They returned to the first motel to get some dinner, but
were refused. Confused that in such a small town they would turn away so much
business, the chasers went to the pub and  had an all you can eat BBQ there.
After dinner most of the chasers went to watch videos, but 4 stayed at the
pub. The 4 had a couple of drinks, then a couple more.. and so on, and it
seemed that 1/2 the town was in the pub drinking it up with the chasers. Word
got out that the river just to the east of town was about to flood the bridge.
The concerned chasers watching the video's went to investigate, and upon their
travels came across the chasers in the pub, playing pool and in a very happy
mood with the locals. They warned the 4 chasers of the imminant danger of
being stuck in Thargomindah for a week or 2 if water rose over the bridge, but
our 4 chasers cheered in delight at the thought of being in the pub for 2
weeks in the middle of know where.
 The group inspected the river level and decided that it was safe to stay the
night. Everyone soon went to bed, but after the 4 chasers hit bed after a big
night out in Thargomindah , shouting could be heard as a domestic raged
outside with the pub owner and his girlfriend, wife, sister..(probably all 3)
. This went on for some time and was apprarantly caused by the 4 chasers
getting half the town drunk.
Rumour also states that one chaser could not handle his alcohol very well and
made the toilet bowl his best friend for a short time ;)
The next morning the chasers arose to big headaches, drizzly and overcast
conditions in SW QLD in late November. I believe they were also wearing
jumpers as it was below 20C.
They left the lively metropolis of Thargo, the deformed inbread dogs they had
made friends with in the town, and the locals, the fowl underground water
which some refused to shower in ... but not before purchasing post cards of a
dust storm approaching the town...a snap shot of what they were hoping to see.

Such is the legend passed down from one storm chaser to the next...

The latest 10 day MRF output seems to suggest that the patterns will get
back to 'normal' for this time of year within the next week.

That would be good - maybe we'll get some wintery weather before it's
spring!

The combination of a surface low moving NE from the west coast of
Tasmania, around King Island & towards Victoria, a trough at 300hPa &
500hPa temps of -23C had at least 3 of us out the door today. Cbs in
Bass Strait mid morning & congesting Cu & Cbs W, NW & N of Melbourne
shortly after had Andrew McDonald in the Whittlesea area in heavy rain,
me on Doncaster Shoppingtown (how did they know to leave that particular
car space free???) & Robert Goler patrolling the E suburbs for a couple
of hours. No lightning in the Melbourne area & no hail - but it looked
absolutely brilliant (if only it had been 28C at the surface....). Goes
to prove that it's not just Brisbane who can take happy snaps of Cjs in
June!!

Is it really June? The ground temperatures haven't dropped enough to
bare the cypress trees & I've never seen daffodils quite this early!!!

Hi Andrew and all,

Well, the latest model runs are still suggesting some fairly cold air to
pass over the south east later in the week. It doesn't look amazing or
anything but at least there is some agreement on it happening. Tuesday
nights run will be when I take a little more notice.

For those that are interested, check out my June weather obs at
http://www.lisp.com.au/~violin/june.htm  Its been pretty mild of late. Use
them as a guide only.

Hi Jane,
Just adding to your note about the daffodils flowering, ours have flowered 
early too!! I was quite suprised. Last year they flowered in early 
september. Our Franjapeny trees (is that how it's spelt?) that are notorious 
for not growing leaves until late spring/early summer has already begun 
growing leaves and flowering. Everythings rather confused up here. Hopefully 
the 'normal' weather shall return this week!

In the 1950s there was a rumour going around the country folk (and around 
the school) that Mt Warning would probably blow in the next fifty years, 
but as far as I can recall there was never any believable scientific 
explanation associated with it.  It may possibly have been an aboriginal 
legend that became stretched out of shape.
It didn't blow yet so whoever started it got their time frame wrong.
Actually, I cannot remember now exactly where Mt Warning is located.  Can 
somebody remind me?  I haven't been back to Western Vic. since the 1960s.

Phil,

I presume the Mt Warning they are talking about is the volcanic plug in far
NE NSW.

It creates the very distinctive sky line visible from beaches from Byron Bay
north to the Qld border.

Hi all,

Looks like some potentially interesting weather for the Maroon's
thrashing of the Blue's tonight :-)

Weak trough is slowly moving up the coast, it looks like it'll weaken a
little further (in response to a weakening high anyway, reducing the
convergence area). But GMSD does look interesting, you can see the
trough line and the convective line. Upper temps are quite cold in
Sydney, not progged to get much colder though, -4C  at  700mb, -20C  at  500mb
and -47C  at  300mb - sitting in the tip of the upper trough. Some rather
steep lapse rates there though.

What we will see though is a strenghtening of the isothermal gradient
over the Sydney region in response to the upper level trough moving
through from the west over SA pushing the upper level ridge ahead of it
further eastwards. This would result in stronger upper winds over Sydney
- might be enough to give some showers the extra edge to take the extra
step?

The trough really straddles the coast...but I wouldn't be surprised if
there's at least some lightning out to sea tonight, with the risk of TS
activity inland also. Perhaps they won't need fireworks :-)

Any thoughts?

Hi Tony,

That is 136.5 degrees Kelvin, which translates to -136.5C.  John is
right, twice as cold of 0C is -136.5C.  This was the reason why the
Kelvin scale was introduced, so that if you doubled the temperature, you
had a physical relationship where the heat content doubled.  Ie, 400K is
twice as warm as 200K, but 40C is *not* twice as warm as 20C.

hmm... This Might sound like a stupid question... but im wondering... This 
is a pretty strange theory of mine but is it possible that based on the 
theory that updrafts/downdrafts in storms create friction between the ice 
particles in teh storm ... could the thunder after the lightning help 
promote friction between the ice particles furthermore?

Since Ice is a Solid, All sounds should be projected off them, causing 
vibrations to take place. If yu get 3 seconds of decent thunder, say enough 
for you to easily hear, Could the thunder cause the friction between each 
two ice particles to be amplified thru vibrations from the sounds thus 
helping promote further lightning? If the updraft/downdraft of the storm is 
able to create one strike of lightning, which in turn produces thunder, 
which gives a short boost to the charge in the cloud, with the help of the 
updrafts/downdrafts help produce more lightning, etc etc etc until the 
updrafts/downdrafts decrease to a point where the thunder cant cause the 
extra friction nessassary to produce more lightning. Call it a semi self 
efficant lightning domino effect...

Anyone got any opinions on this? or any other theories that stem from 
lightning creation theories?

Cheers,

Michael Olsen

Just to add a twist to the interesting Domino effect theory Michael has put
forward, considering sound is based on compression waves and a decent 3
second thunder clap is pretty LOUD MAN, thus very high energy compression,
would it not simply shatter the ice particles?

Southwest Tasmania broke a few long-standing rainfall records last night.
The combination of *that* low that has been hanging around South Australia,
but overnight drifted down the Tassie west coast, plus a cold front skirting
the south coast, plus a lot of humid air dragged down from the north ahead
of the low gave a few hours of torrential rain during the evening.

Maatsuyker Island off the south coast recorded 40.6mm between 4pm yesterday
and midnight for a 24 hour total of 49.0, breaking the old June record of
46.7 in just over a century of records. Cape Sorell, halfway up the west
coast, recorded 56.0 for the 24 hours (the old June record was 55.4 in 70
years of computer record, and the all time record is 66.0). But 46mm of that
fell in the 3 hours period to 1am. Tasmania's west coast is renowned for its
wetness, but it's not usually that heavy.

Interestingly, totals away from the south and west coastal fringes dropped
off rapidly. Strahan Aerodrome, only a few km from Cape Sorell, recorded
only 13mm, Queenstown 10.2, and the notoriously wet Lake Margaret only 36.2
for the 3 days to 9am. However, the hourly satellite-transmitted reports
from the Cape Sorell AWS are internally consistent and look to be valid, the
low was passing just off the coast at midnight, and the hourly water vapour
satpix show an intense but tiny area of moisture on the southern half of the
west coast and around the south coast at the time.

Mt Wellington summit AWS also cracked its relatively short June rainfall
record for the second time in three days. The previous highest June one-day
total in 15 years' record was 23.6mm. The AWS recorded 25mm on Thursday, and
33mm this morning.

Hi all,

Just another record from earlier in the week:

I don't think my email got through to the list earlier in the week but in
the 24hrs to 9am Saturday morning, St George in south Queensland recorded
its highest 24hr June rainfall with 78mm (previous record being 57.2mm).

Regards

Andrew McDonald

Hi Michael,

I'm not sure!  It's an interesting theory, I was thinking back to a few
things I have observed.  That is sympathetic lightning, you can have a
line of storms 10-30km long and one cell at the end of the line will
produce a lightning strike, then the next one in line, and the next, and
the next etc, so you get a chain reaction!  But it happens over a couple
of seconds, which would suggest that the shockwave produced by thunder
which would take longer than several seconds to travel across would be
too slow to produce this effect.  Rather, it would be something to do
with the charges and electromagnetic forces, as they travel at the speed
of light which is more in the time frame we're looking at here.

As for whether it would occur in one storm itself, again I'm not sure -
the shockwave is pretty powerful when you are close to it - Clyve
Herbert from this list had his car pushed by a shockwave in Glenn Innes
on TD2K when a lightning strike hit a building he was driving by! 
However, if you are very close (over extremely close), you don't seem to
get much of a shockwave from what I've experience, just one high pitched
crack and that's it - where as if you are 100-200m away, you can
sometimes feel the thunder.

Hey all

Speaking of records, and with another 15mm or so overnight in Adelaide and
more to come later this week, and considering that we are only 11 days into
the month, i wonder what the chances are of us breaking the June rainfall
record?  Things are pretty sodden here and my backyard is a lake....again.
Still fairly mild though.

Phil

Hi all,

Jimmy here for those who forgot who I am. As most of you know, David Croan 
and I have been away from Sydney chasing storms in the United States. Well 
we tried to chase them anyway. For those in NSW or perhaps visiting NSW, I 
understand there is a meeting on about our chase expeditions in the United 
States on the 16th June 2001. I had requested it be put back on the 3rd 
Saturday of the month rather than the traditional second Saturday of the month.

Now there has been speculation as to what we got in the United States - I 
suppose you will have to come along and find out. Cheers.

Glad you are back safe and sound Jimmy! I was a bit concerned for Jimmy 
while waiting at Dallas Fort Worth. We  left on separate flights, though 
from adjacent gates. As my SFC bound flight pulled out from the gate I 
noticed that Jimmy's flight, which was due to take off 5 minutes before 
mine, was still parked and with what appeared to be every man and his dog 
(Jimmy!!!) inspecting the left wing of the 737. Given his tight flight 
schedule I thought he might have been spending the night at LAX.

Anyway it has been a truly memorable trip. The storm chasing was far from 
easy going in what Tim Marshall rated a 2/5 year a few weeks ago. Yet we had 
some excellent results, plenty of funny moments, chaser convergence, TV 
interviews, you name it. We used the same chasing strategy that we both use 
in Australia, relying only on the same forecast models and most importantly 
our own eyes to monitor the evolving weather.

hope some of you are able to share the adventure on Saturday night at the 
NSW meeting.

I am looking at buying a property in the Oberon area & would like to
know the height of surrounding localities including Black Springs,
Edith, Porters Retreat, Mt. Werong etc. Does anyone know the heighest
locality in the Oberon area? Also the Oberon web site notes there is an
area at around 300 metres. Where would this be?

Damian, I'm not sure of the heights, but I do know that Edith and Black
Springs get more snow than Oberon itself.  I have just been going through
some of my geography notes on Oberon, but do not have the  physical
geography details, just population and demographic details.  Perhaps a map
might help with the heights of the area, again, I no longer have those as I
have moved away from the Central West.  Perhaps contacting the Land
Information Centre in Bathurst they might be able to give you some
information as well.

Hi Anthony

I agree with that, if you are with in 20m or so of a strike, you get a short
"crack" and nothing else, but that short crack is VERY loud!... where as a bit
further away and it souds like a hundred whips cracking at once, and you can feel
the boom thundering through the car.

Nice to have you back on board Jimmy/David,  hope you can both make it on TDU
this year, over a piddly trip to see boring US storms :)

Missing a 1 there, should be 1300m, which puts into more than freak fall
snow territory. I think Shooters Hill is around 1300m.

Is pileus cloud where you have cirrus like stuff over the top of a Cumulus 
cloud? I saw some today near Brisbane on a small cumulus cloud.

Also could someone clearly show me difference in look of gust fronts, wall 
clouds, shelf clouds and roll clouds? Thanks,

Im slowly working on it, most of the stuff there works. A brief run down on
storms stucture etc with photos.

You are correct about pilius...this should help you a bit :

Black Springs is at 1210m. All the areas south of Oberon range between
about 1000 and 1300m.

And when you are the target of a direct hit as I was years ago you hear 
absolutely nothing at the moment of the strike - just blinding light (I 
was blinded for quite some minutes), searing heat (effects like a severe 
sunburn), and a dreadful feeling that something is terribly wrong (pains 
in the chest and guts).  Then came the echos of the big bang seconds 
after the event.  I had no idea that it was lightning until told by the 
driver of a car that had been following my motorbike about two hundred 
metres behind me.

On another occasion lightning struck a discarded engine block 12 feet (4 
metres) from where I was standing and I heard that one immense crack that 
Matt mentioned.  This was followed by a ringing in the ears which had 
been temporarily deafened by the first crack and only as the ringing 
lessened could I hear the echoing part of the thunder.  On that occasion 
also my face was "sunburnt" by the radiant heat from the lightning.
The shockwave felt like it went right through my body instantly as the 
lightning struck and was quite similar to the shockwave you feel when a 
powerful bomb explodes nearby (though most of you are probably too young 
to have had that experience).

G'day Damian,

My neighbours are in the process of moving to Oberon as I write. Shooters
Hill area is quite high, the settlement there is in the 1200 metre range and
recently that lovely, old, renovated church was for sale there, at a
reasonable price. Black Springs is a similar height and has an all bitumen
road to Oberon. Some decent houses there in the 100 to 130 thousand mark.
Edith, the settlement, is around 1080 metres and is within easy drive (good
bitumen and gravel) of  Oberon township. Continue driving towards Jenolan on
the Edith road and it gets higher, 1362 metres to be exact at Mount Trickett
and there is a radio tower there, some holiday cabins and two or three
houses just before the drive down to Jenolan Caves. This spot is my first
stop in marginal snow conditions. These are the spots I know quite well as
well as the farms to the east of Oberon which are in the 1000 to 1100 metre
range.

There are plenty of nice spots in this area, including small acreages/hobby
farms at a good price. I'd recommend a visit to the agents in the area. See
my site for snow photos in the Shooters Hill area. They can get HEAVY snow
there. 4WD drive territory for sure, in winter.

Does the shockwave travel at the speed of sound or faster?
I have observed the "chain reaction" lightning flashes along 20 or 30 km 
of cells and it travels very much slower than the speed of light and very 
much faster than the speed of sound.
If the shockwave is limited to the speed of sound then this effect is not 
caused by the shockwave, but if the cause is 
electrical/magnetic/whatever, then there is something which slows it very 
significantly below the speed of light.

Hey

It is a good point that you put forward about how the ice particles would be 
likely to just 'shatter'but logically this would only promote the cause 
furthermore. If each ice particle was to say break into two seperate ice 
particles then it would increase the charge made dramatically from the 
increased surface area from the ice particles seperation. This would give 
the storm a boost in its ability to sustain a higher charge and help produce 
further strikes.

But must be off,

Cheers,

Michael Olsen

I've posted a few images of the supercell at sunset and the highway 160
funnel, perhaps tornado, at:

I'll post a few more images from this day later this week.

Good luck to anyone chasing today.  I'd favor the Nebraska panhandle
today, even though the tornado probabilities are lower, the air is
clearer and the views better than in the moderate risk.

I dunno Michael. If this was indeed the case then we would be able to have
perpetual motion. If the ice particles are smaller, then would you not have
a weaker charge generated by the friction as there is a deficit of surface
area and thus a lower friction generated force even though you have more
particles.

Ahh. Come to think of it, you would probably have very close to the same as
(taking into account the losses due to heat and atmospheric dissapation of
charge energy) there would be weaker charge, but more of them.

Darn, back to the ol' drawing board for me.... :-) I never thought physics
would come in handy!

I am trying to get my vehicle ready for chasing this summer. Currently my 
windscreen wipers are stupid. In light rain you are better off without them 
and in heavy rain they ain't much better. I think the blades are worn out :-).

I was just looking for recommendations on the best brands and types for storm 
chasing, also do those things you can wash your windscreen with to help water 
move off quicker work? Some sprays claim they do. What would you guys 
recommend to me?

Some complex questions for people who understand radar:

1.  What frequencies reflect best off of rain. I have a chart showing 
attenuation vs rain rate vs frequency, but what about reflections.

2. Could I use a subtractive system to listen for reflections, but cancel out 
direct signal from an FM radio station at a certain distance, and use this to 
form radar patterns?

3. Could I listen to the frequency used for BOM radar, knowing that anything 
I pick up will be reflection not the direct signal(because I am below the 
horizon of the radar).

For 2 and 3 assume a rotatating radar antenna like on a ship. I just want to 
know if I can derive radar without transmitting, given that I know my 
position and the transmitter location. Thanks,

David

need for the wipers. Similar to the beading that happens on a newly polished
car. Apparently if I remember it was also good for repelling frost etc but
can't remember. Hope this helps.

Subject: aus-wx: Bombed out by lightning!
Sender: aussie-weather-approval at world.std.com
Reply-To: aussie-weather at world.std.com

About fivish this morning I attempted to send you an email re current.htm
but got bombed by lightning about a second after hitting the "Send"
button, so dunno whether you got it.  Anyway, if you didn't, look for
yourself.
Our building was struck by lightning four times this morning in about ten
minutes.  The third strike took out all power and communications for a
while.
This is our ninth straight day of Thunderstorm Warnings by the HKO and
the TSs have been around several times each day.  Often we get hour after
hour of continuous lightning and thunder.
The North Western New Territories is utterly flooded with loads of people
having to be winched from their house rooftops by helicopter.
Thousands of homes and cars are underwater and many roads are closed.
There have been landslips and numerous other weather-related calamities.

And everything is just plain, dripping wet!

The RH has been alternating between 98% and 100% for day after day after
day.

Can't get any sleep at night due to the din of the thunder.

The Sha Tin AWS was taken out by the storm at 03:00 today so I can no
longer keep tabs on Temp and RH.  At around 03:00 the Temp dropped
instantly from 25C to -10C and the RH has simply stayed stuck on 100%.
(See
http://www2.info.gov.hk/hko/wxinfo/ts/display_graph.htm?chinese=0&stn=sha )
I suppose it may be out for days as HKO will have
higher priorities than fixing busted AWSs.
I must describe the lightning strikes this morning:
There had been many hits within 100m or so, when suddenly I felt my hair
all standing on end.  Even the hair on my arms was standing on end.  This
hair-on-end bit was inreasing steadily and quickly and there was an
electrical hum and a crackling all around me arising at the same time.  I
kept typing my previous e-mail to you.  With the raising of hairs there
was also a "tightness" of some sort rising up across my chest.  I dunno
if that might have perhaps been "psychosomatic" since I knew from past
experience what was about to hit.
Suddenly, instantly, this rising crescendo of electrical activity utterly
collapsed as there was a blinding flash of lightning but NO BANG outside,
just the loud crack of collapsing electrical fields inside.  For some
reason, when lightning hits our house I never hear the instant BANG but I
hear the echoes from all the other buildings first.  Then the thunder
rises up enormously loud.  Instantly after the flash there is a stream of
molten metal falling past outside the window from the lightning conductor
mounted directly above the window.  It's like somebody is welding a floor
or two above.  As the echoes of thunder become louder, so too do the
pressure waves or shockwaves as they are reflected by the surrounding
buildings.  They just seem to go right through you.
At the moment of the strike, when all the other electrical activity in
the room collapses, the tightness across the chest is also immediately
relieved.
So this happened four times in ten minutes this morning. Twice while I
was typing my previous e-mail to you, once less than a second after I had
hit "send", and once again a couple of minutes later.  All power was out
for about 10 minutes - and this in spite of our so-called "storm-proof"
underground electricity reticulation system.
Actually, although I have been through it several times before, it is
always still very scary when you feel that hair start to stand on end.  I
understand that the lightning conductors overhead are supposed to keep us
protected inside, but you still feel like you're about to get obliterated
or something.
There is no way I will go out for my morning exercise on the river bank
while these storms are lasting.
All of the Territory's schools have been closed again today by the
Education Department because of the storms, so it's playing havoc with
end-of-year activities, examinations, etc.
Now, here it all comes again so I'm going offline.  You may forward this
to Aussie-weather if you like.  I won't be online again until this lot
quietens down.

Ooroo fernow,

Phil

Would this work: Put a cup anemometer on the roof of your car. Add a digital 
speedometer. Subtract the car speed from the anenometer speed to get the wind 
speed while driving?

Also anyone know of a good source for cups for anenometers?


Thanks

Thanks. How long does it last usually? Just wanted to know if it was worth

You'd need a direction sensor as well so that you could perform an accurate
vector subtraction to obtain the true wind speed.

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

Hi David,

There were some nice CJ's around yesterday, but I didn't see any
pilerus.  Had the updraft punched through the Cirrus, or was there just
Cirrus above the cloud?  You said it was a small cumulus cloud, pileus
requires the temperatures around the vicinity to be very cold (as you
need ice crystals to form), so if it was small Cu it would be unlikely
to be pilieus, but there can be exceptions.

To add some more to what Matt Smith said - "gust front" clouds and
"shelf clouds" are the same - shelf clouds form on the gust front, gust
front or 'guster' is chaser slang to mean shelf cloud (guster sounds
better!)

Shelf clouds are the boundary of inflow and outflow of the storm, as the
cool air pushes ahead, it lifts the warm moist air ahead of the storm
and it condenses.  A few examples:

http://www.bsch.au.com/photos/anthony/241198_06.shtml
http://www.bsch.au.com/photos/anthony/120301_07.shtml
http://www.bsch.au.com/photos/anthony/050100_01.shtml


Roll clouds are just a detached shelf cloud that has moved ahead of the
storm.
http://www.bsch.au.com/photos/anthony/181100_02.shtml

Wall clouds are inflow areas, found under or near the main updraft of
the storm - they are a rotating lowering, and are inflow dominated.
http://www.bsch.au.com/photos/anthony/211100_06.shtml
http://www.bsch.au.com/photos/anthony/191100_03.shtml
http://www.bsch.au.com/photos/anthony/041100_02.shtml

I have other examples of wall clouds in my chase reports which are
better, but the first example is pretty good.  If you go through my
chase reports on BSCH there's quite a few examples of WC's, and other
features too!  It's just a matter of having a look around David, best
thing is experience.

Hi Phil,

True - although I still think it has something to do with the difference
of charges.  There is a lag between the effects - it takes a while for
charge to build, and eventually discharge (all under a second though).

But a cup anenometer doesn't give you direction. It just gives you the total 
air speed. I don't see how direction comes into it???

Hmm - never noticed much of a different with windscreen wipers, they all
do the same job for me.  I always keep a spare set in the car incase it
breaks, I'd suggest giving them a clean if they are smudgy.  Also, if in
light rain they don't do much good - most wipers don't work well dry,
they need to be moist to get rid of the rain properly.

Rain-X is good, around $5/$6 a bottle, but you'll have to re-apply it
every few chases or so, or every 2-4 weeks if you don't do any chasing.

This would go for both the car's vehicle, and the direction of the
wind.  You'd need to get a special compass that caliberates itself to
the magnetic field of the car, as there would be a different field in
the car and also outside of the car.  Then you'd need to build a
program, and most probably power it using a laptop.  It's been something
I've thought about it, but the logistics and costs of it are too much
for what it's worth.  For now, I stick to the Beaufort scale, and again
experience in estimating winds - I have an anneometer at home, so that
allows me to get a good idea for winds speeds.

My advice would be to turf you wipers and the arms too. Most wipers need the
wiperblade changed very year, but many don't think of the actual wiper
itself. It is of vital importance to stop the wind lifting the wipers off
and thus not doing an effective job.

I think rain x while a good invention for a dry climate. It will wash off
your car if you get a few spells of rain. Just keep your wiperwasher fluid
nice and soapy (i put windex in it) and that will keep your windscreen
clean. Also wax keeps your windscreen cleaner for longer, so if you give
your car a wax, don't forget the windows.

If you want to know where the wind is coming from, then you would need a
direction sensor.  But if you're simply interested in wind _speed_, then
the cup anemometer method as David previously described would work fine,
as a cup anenometer measures the wind speed no matter what direction it's
coming from.  It would simply add to the speed of the car.  That is, if
the car is heading north at 60 km/h with a 30 km/h easterly blowing, the
cup anenometer would be reading 90 km/h.  So, unless there is absolutely
no wind blowing, the anemometer would be reading a speed greater than the
speed of the car.

Actually Robert that is not correct. If the car is going north at 60kmh and
the wind is from the east at 30km/h, the cup anemometer would read 67kmh
which is the vector addition of the two velocities. So a direction sensor is
essential even if you only want a speed reading.

<DIV></DIV>&gt; 
<DIV></DIV>&gt; &gt; I have just returned from a two day conference in Canberra. I must admit 
<DIV></DIV>&gt; &gt; Lake George was a bit of shock and I could not see any water at all. There 
<DIV></DIV>&gt; &gt; could be some at the extreme SE end, but I would not bet on it. 
<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt; It is a sad barometer of the general climate of the last decade for that 
<DIV></DIV>&gt; &gt; area. I go to Canberra 1-2 times a year and started in 1993. That year the 
<DIV></DIV>&gt; &gt; lake was almost lapping the edge of the Highway. 
<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt; Given the fence lines the recent dry is something that has occurred 
<DIV></DIV>&gt;before. 
<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt; I wonder however about fish. I have read that Lake George once supported 
<DIV></DIV>&gt; &gt; commercial fishing, surely the dry periods of the past would have been 
<DIV></DIV>&gt;near 
<DIV></DIV>&gt; &gt; as bad ? Do the fish hole up in isolated waterholes of some feeder creeks, 
<DIV></DIV>&gt; &gt; only the explode Lake Eyre like when Lake George fills again ? 
<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt; Also noted how dry things are in Canberra. I realise that frost burn does 
<DIV></DIV>&gt; &gt; brown things, but we are talking serious dryness.

<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt;

<DIV></DIV>&gt; &gt; &gt; Lake George is not supposed to be a dust pan - it generally does have

<DIV></DIV>&gt; 
<DIV></DIV>&gt;And when you are the target of a direct hit as I was years ago you hear 
<DIV></DIV>&gt;absolutely nothing at the moment of the strike - just blinding light (I 
<DIV></DIV>&gt;was blinded for quite some minutes), searing heat (effects like a severe 
<DIV></DIV>&gt;sunburn), and a dreadful feeling that something is terribly wrong (pains 
<DIV></DIV>&gt;in the chest and guts). Then came the echos of the big bang seconds 
<DIV></DIV>&gt;after the event. I had no idea that it was lightning until told by the 
<DIV></DIV>&gt;driver of a car that had been following my motorbike about two hundred 
<DIV></DIV>&gt;metres behind me. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;On another occasion lightning struck a discarded engine block 12 feet (4 
<DIV></DIV>&gt;metres) from where I was standing and I heard that one immense crack that 
<DIV></DIV>&gt;Matt mentioned. This was followed by a ringing in the ears which had 
<DIV></DIV>&gt;been temporarily deafened by the first crack and only as the ringing 
<DIV></DIV>&gt;lessened could I hear the echoing part of the thunder. On that occasion 
<DIV></DIV>&gt;also my face was &quot;sunburnt&quot; by the radiant heat from the lightning. 
<DIV></DIV>&gt;The shockwave felt like it went right through my body instantly as the 
<DIV></DIV>&gt;lightning struck and was quite similar to the shockwave you feel when a 
<DIV></DIV>&gt;powerful bomb explodes nearby (though most of you are probably too young 
<DIV></DIV>&gt;to have had that experience).

<DIV></DIV>&gt; &gt; Hi Anthony 
<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt; I agree with that, if you are with in 20m or so of a strike, you get a 
<DIV></DIV>&gt; &gt; short 
<DIV></DIV>&gt; &gt; &quot;crack&quot; and nothing else, but that short crack is VERY loud!... where 
<DIV></DIV>&gt; &gt; as a bit 
<DIV></DIV>&gt; &gt; further away and it souds like a hundred whips cracking at once, and 
<DIV></DIV>&gt; &gt; you can feel 
<DIV></DIV>&gt; &gt; the boom thundering through the car. 
<DIV></DIV>&gt; &gt; 
<DIV></DIV>&gt; &gt; Nice to have you back on board Jimmy/David, hope you can both make it 
<DIV></DIV>&gt; &gt; on TDU 
<DIV></DIV>&gt; &gt; this year, over a piddly trip to see boring US storms :)

<DIV></DIV>&gt; &gt; &gt; Hi Michael, 
<DIV></DIV>&gt; &gt; &gt; 
<DIV></DIV>&gt; &gt; &gt; I'm not sure! It's an interesting theory, I was thinking back to a 
<DIV></DIV>&gt; &gt; few 
<DIV></DIV>&gt; &gt; &gt; things I have observed. That is sympathetic lightning, you can have 
<DIV></DIV>&gt; &gt; a 
<DIV></DIV>&gt; &gt; &gt; line of storms 10-30km long and one cell at the end of the line will 
<DIV></DIV>&gt; &gt; &gt; produce a lightning strike, then the next one in line, and the next, 
<DIV></DIV>&gt; &gt; and 
<DIV></DIV>&gt; &gt; &gt; the next etc, so you get a chain reaction! But it happens over a 
<DIV></DIV>&gt; &gt; couple 
<DIV></DIV>&gt; &gt; &gt; of seconds, which would suggest that the shockwave produced by 
<DIV></DIV>&gt; &gt; thunder 
<DIV></DIV>&gt; &gt; &gt; which would take longer than several seconds to travel across would 
<DIV></DIV>&gt; &gt; be 
<DIV></DIV>&gt; &gt; &gt; too slow to produce this effect. Rather, it would be something to do 
<DIV></DIV>&gt; &gt; &gt; with the charges and electromagnetic forces, as they travel at the 
<DIV></DIV>&gt; &gt; speed 
<DIV></DIV>&gt; &gt; &gt; of light which is more in the time frame we're looking at here. 
<DIV></DIV>&gt; &gt; &gt; 
<DIV></DIV>&gt; &gt; &gt; As for whether it would occur in one storm itself, again I'm not sure 
<DIV></DIV>&gt; &gt; - 
<DIV></DIV>&gt; &gt; &gt; the shockwave is pretty powerful when you are close to it - Clyve 
<DIV></DIV>&gt; &gt; &gt; Herbert from this list had his car pushed by a shockwave in Glenn 
<DIV></DIV>&gt; &gt; Innes 
<DIV></DIV>&gt; &gt; &gt; on TD2K when a lightning strike hit a building he was driving by! 
<DIV></DIV>&gt; &gt; &gt; However, if you are very close (over extremely close), you don't seem 
<DIV></DIV>&gt; &gt; to 
<DIV></DIV>&gt; &gt; &gt; get much of a shockwave from what I've experience, just one high 
<DIV></DIV>&gt; &gt; pitched 
<DIV></DIV>&gt; &gt; &gt; crack and that's it - where as if you are 100-200m away, you can 
<DIV></DIV>&gt; &gt; &gt; sometimes feel the thunder.

<DIV></DIV>&gt; &gt; say enough 
<DIV></DIV>&gt; &gt; &gt; &gt; for you to easily hear, Could the thunder cause the friction 
<DIV></DIV>&gt; &gt; between each 
<DIV></DIV>&gt; &gt; &gt; &gt; two ice particles to be amplified thru vibrations from the sounds 
<DIV></DIV>&gt; &gt; thus 
<DIV></DIV>&gt; &gt; &gt; &gt; helping promote further lightning? If the updraft/downdraft of the 
<DIV></DIV>&gt; &gt; storm is 
<DIV></DIV>&gt; &gt; &gt; &gt; able to create one strike of lightning, which in turn produces 
<DIV></DIV>&gt; &gt; thunder, 
<DIV></DIV>&gt; &gt; &gt; &gt; which gives a short boost to the charge in the cloud, with the help

<DIV></DIV>&gt; &gt; &gt; &gt; updrafts/downdrafts help produce more lightning, etc etc etc until 
<DIV></DIV>&gt; &gt; the 
<DIV></DIV>&gt; &gt; &gt; &gt; updrafts/downdrafts decrease to a point where the thunder cant

Hmm,

This must be some new branch of mathematics I havn't come across before...
What happens if the wind is blowing directly from behind you?  Obviously the
anemometer would then be reading less than the speed of the car.

I'm afraid vector arithmetic is most definitely required and you do need to
know the direction of the resultant.

John.
>snip

It would simply add to the speed of the car.  That is, if
the car is heading north at 60 km/h with a 30 km/h easterly blowing, the
cup anenometer would be reading 90 km/h.  So, unless there is absolutely
no wind blowing, the anemometer would be reading a speed greater than the
speed of the car.

A bit of an incomplete statement there by myself.  

Of course, if the wind has a component from the rear of the car, the
speed registered by the anemometer will be less than the speed of the car.
ie a 60km/h southerly with the car moving 60km/h to the north, the
anemometer will register 0, but once you subtract out the car speed, you
get the wind speed.

I disagree.
If you were driving North at 60 kmh and there was a steady Southerly of 
exactly 60 kmh then the anemometer would not turn at all giving a reading 
of dead calm.
f you are driving North at 60 kmh into a Northerly of 60 kmh the 
anemometer would register 120 kmh.
Of course I know the wind won't be that steady, but it illustrates the 
point.
The direction component is necessary I think.
If whoever started this thread ever actually builds it, I would love to 
see a photo of it!

Therefore a direction reading is definitely a requirement.

I was getting worried there Robert. I studied mathematics at Monash and we
certainly learned a different set of world rules to the one you described :)

Hi all,

If you believe the latest GASP it will be bloody cold in the south east,
even in Blackheath, by Thursday/Friday. Other models are less impressive
although still pretty cold and some moisture, too. The BOM has sleet for
higher parts, with Orange going for a min of  3C  and a max of  7C on
Thursday. Higher parts south of Oberon could see snow. NoGaps has a nice
cold pool over most of  NSW during the same time, too. MRF alright as well.
Anyone got a view of  EC?

Cheers,

Well I've always wondered about similar things. Not weather related but I've
always wanted to know and now's my chance.
Theoretically a bullet leaves a gun at 100kmh. I'm driving at 100kmh and I
fire my gun out the back, will it just stay stationary and then fall on the
ground?
If I fire it out the side as mentioned here will it curve away with the wind
and then fall on the ground.
This is Physics isn't it? Way outa my league but I've always wondered.

Hi all,

Got home from getting take-away and dad told me that Channel 9 had
footage of a waterspout near Russell Island in Moreton Bay, just off
Brisbane!  There was some very nice Cu around today, and later in the
afternoon a line of showers went through Brisbane from the coast.

Not sure what time it was though...anyone have any further info?

Hi Lindsay and all,

Well, after this cold weather being downgraded over successive runs, the
current run looks really good again. It's time for the snow hounds around
the area to get ready to feel ill at work as the change approaches and the
temp falls. I know I'll be hounding the list and those with net access to
keep me updated during the day with radar returns and temps further down
along the south coast. I notice they are going for Bega to have a top of 11
degrees tomorrow which is pretty low for them. So, what's the guess for
timing of the change at this stage?

Also, I know this was mentioned some time last year, but what sought of
thicknesses would be required for snow to around 600-700m? This is of course
assuming there is sufficient moisture around.

Now for my read of GASP, I notice it shows a centre of 531 somewhere a
little NW of Sydney for Friday at 00UTC, and with the positioning of the
surface low I can only hope to see the main push of coldest air coming from
a little closer to S rather than SW, SE would be even better. The thickness
line seem to hopefully indicate the air pushing in from the SE with
sufficient moisture for a repeat of July 27th last year. Which brings me to
another question, what where the thicknesses associated with that outbreak?

Anyway, here's hoping, and I'd be interested to hear if anything is able to
correct my guesses from the model.

Cheers
Andrew Godsman

Sorry, have to disagree with that.  The cup anemometer would measure
the total vector wind, not the sum of the winds.  Sum is a scalar
quantity.  A wind has a direction (a vector quantity) and so does the
car.  Sum two vectors is not the same as summing to scalars.

Couldn't help but get into this one. You have to take into account that the 
bullet at some stage was at rest - not moving so it has to accelerate. So 
it is not as simple a problem and we have to take into account the impulse. 
I will leave it there.

In general, yes the bullet will eventually drop to the ground after making 
a hole into the window but the car will go away from the bullet and it 
should drop somewhere near where it was first fired.

Why damage windows with bullets - just let giant hailstones do the trick

Ok guys,

for those of us who failed the Public Service entry exam because of our
a) non-grip of logic &
b) failure in physics,
could we please have this discussion translated into easy to understand
english (preferably with working examples to help us scramble up to
somewhere approximating a level that we aren't embarrassed about)

i) please define vector
ii) please define scalar
iii) please could we have a couple of examples.

Many thanks,

your student

Jane

Hello David!

12 Jun 01 13:21, you wrote to All:

Rain scatter occurs most readily at frequencies in the GHz range and higher.
There are some excellent sites that describe the characteristics of rain
scatter.  From what I recall, the scattering/reflection increases in proportion
to the 4th power of the frequency (i.e. double the frequency = 16 x
reflection), until the wavelength approaches the size of the droplets.  Don't
quote me on it, but some of the amateurs who play around on microwaves have put
up some excellent papers on the subject.  Look up "rain scatter" on the web.

Broadcast FM is way too low in frequency.

Maybe.  I don't know the frequency or power levels of the BOM radar

You can derive that there is rain "somewhere".  Direction should be obtainable,
but the intensity readings may be a bit iffy, as there's a lot of variables
involved.

hi everyone,
  I have once again changed servers with my site (sorry for any 
inconvenience). This time to a FASTER, more RELIABLE server and with NO POP 
UP ADD BANNERS!!  :-)  yippeee
  I have a domain set up; www.anvilindustries.com  that directs to the new 
server ( http://bigmax.yi.org/users/anvils/ ).
  so if you could/would like to update your bookmarks/links (if you have any 
or care) that would be greatly appreciated.It is entirely upto you if you 
choose to link the 'actual URL' or the redirecting domain 
(www.anvilindustries.com )but hopefully the domain will be better for the 
longer term.

Thank-you and once again sorry for any inconvenience.

regards Tony.

PS. if you have any queries, problems with links or errors feel free to 
email me.

Hi Jane,

I'll do this in a slightly different order...

1) A scalar simply just has a magnitude, with no direction.  Ie, it is
27C, there are 10 supercells in that line, etc.

2) A vector has a magnitude and a direction.  Ie, that tornado is moving
at 40km/h <magnitude> to the north <direction>, or that supercell is
moving NW at 30km/h...etc.

If we look at the car example, we want to know the wind speed that would
result if we had a car travelling at 60km/h to the north, and an E'ly
wind at 30km/h.  We'd simply just add the two components as if the total
time was an hour, often cartesian planes are used for this.  But this is
a fairly simple problem, we can just use pythag to work out the sum of
the two vectors.

I've uploaded a small jpg illustrating how the two vectors can be added,
this can only be done with right angled triangles though.

http://www.bsch.au.com/anthony/vectoraddition.jpg

A^2 + B^2 = C^2
3600 + 900 = 4500
C^2 = 4500
C = ~67km/h

Hope this helps...

The last few days have had the most amazing fogs.

Sunday lasting till 9am
Tuesday(today) lasting for what seemed forever lifted about 945AM. One of
the thickest fogs i have ever seen in Warwick. Visibilty was almost
nonexistant

I wonder why the fogs are lasting so long atm

Hi Jane,

In regards to road rules, they've done some road works on the GB (Gatton
Bypass) to Toowoomba, and they've added in a few interesting signs and
oddities:

"Fatigue Zone: Rumble Strips Ahead" - These rumble strips are for tired
storm chasers attempting to make coffee in the car.  These are
conveniently placed so that as the car goes over the bumps, it stirs and
mixes your coffee.  (Rumble strips are like mini-speed bumps in the
road).

The other thing was that now they have politely created crash zones on
the GB - where people can crash at the least inconvenience to chasers
:-)

      <DIV>Hi everyone</DIV>
      <DIV>&nbsp;</DIV>
      <DIV>&nbsp;I'm an avid reader of this list, but being rather clueless when 
      it comes to all things meteorological, I don't say much. But reading this 
      thread got me thinking. So, here goes what will probably be the most 
      boring read you your life :)</DIV>
      <DIV>&nbsp;</DIV>
      <DIV>Firstly Bussie, yes you are correct, if you fire that gun out the 
      back of your car, then the bullet will just drop to the floor, and one 
      fired sideways would indeed curve away toward the rear of the car from the 
      perspective of someone IN the car, much as it would appear&nbsp;if you 
      were standing in a 100kmh crosswind and fired- the wind would blow the 
      bullet off course. However from the point of view of someone sitting on 
      the road side, assuming you didn't just blow their head off, the bullet 
      would appear to follow a trajectory initially at 45 degrees to the cars 
      direction of motion, and curve parabolically toward a direction at 90 
      degrees to the cars motion, as the wind resistance slowed the component of 
      the bullet's velocity in the cars direction. Obviously the wind resistance 
      would also slow the bullet down and it would also curve towards the 
      ground.</DIV>
      <DIV>&nbsp;</DIV>
      <DIV>Now this contraption for measuring the wind speed in a car. In 
      planes, tubes are used with pressure pads in them to measure the pressure 
      of the air rammed down the tube, and hence its velocity. Using 2 such 
      tubes at 90 degrees to each other, all you would need to know is the cars 
      velocity, and you could calculate the winds velocity, and its direction 
      relative to the cars direction. I can't draw a diagram here, so you'll 
      have to use your imagination.&nbsp;Consider 2 such hollow pipes with 
      pressure pads inside placed at right angles to each other (as in a L 
      shape) Now stick this out the window, with one pipe pointing up the road 
      in the direction you are going, and the other off to the side of he road. 
      </DIV>
      <DIV>Now for the maths.&nbsp;Consider some wind blowing at some an angle 
      relative to the cars motion&nbsp;we will call&nbsp; at  (for all the maths 
      purists out there (Jimmy), forgive me, i don't know the ascii code for the 
      theta character). The air pressure in the tube pointing up the road will 
      be due to the cars velocity, and any component of the wind speed parallel 
      to the cars motion. Call the cars motion V,&nbsp;the wind speed&nbsp;v and 
      the&nbsp;total velocity as measured by the tube P^, and assuming the wind 
      isn't coming from "behind" the car, we can generate the equation P^ - V = 
      vcos at </DIV>
      <DIV>The second tube measures purely the component of the wind 
      perpendicular to the cars motion and none of the cars velocity, since by 
      definition, there is no component of&nbsp;a velocity acting perpendicular 
      to itself.&nbsp;Calling the speed measured in the second&nbsp;tube P&gt; 
      we have P&gt; = v&gt;sin at  </DIV>
      <DIV>&nbsp;</DIV>
      <DIV>Two equations:</DIV>
      <DIV>&nbsp;</DIV>
      <DIV>P^ - V = vcos at </DIV>
      <DIV>&nbsp;</DIV>
      <DIV>P&gt; = vsin at </DIV>
      <DIV>&nbsp;</DIV>
      <DIV>Since P^, P&gt; and&nbsp;V&nbsp;are all known, it is a simple matter 
      of rearranging the 2wo equations and substituting one into the other to 
      give values for v (the wind speed) and  at  the angle of the wind relative to 
      the cars motion) hence:</DIV>
      <DIV>&nbsp;</DIV>
      <DIV>v = (P^ -V)/(cos(arcsin(P&gt;/V)))</DIV>
      <DIV> at  = arctan((P^-V)/P&gt;)</DIV>
      <DIV>&nbsp;</DIV>
      <DIV>A simple comparison of V and P^ would show if the wind was blowing 
      from "behind" and the equations adjusted accordingly (cos &lt;-&gt; sin ). 
      Easy to make the device, and the computations would be simple&nbsp;for a 
      computer to do, not sure how&nbsp;you would go about making an interface 
      though. I guess that's where any electronics boffin would come in. </DIV>
      <DIV>&nbsp;</DIV>
      <DIV>I hope i have done the maths correctly, and not bored you to death 
      :)</DIV>

here in toowoomba we get all day fogs!!! but i guess thats to be expected as 
the moist easterly winds rise up the range and hit the cool air. at least i 
think that's what happens.

oh well

till nex time

I use Trico Refills which seem to last the longest, I buy them from Autobarn.

I also recommend Rain-X for the windscreen, the water just flies off like no-ones business. My Volvo already has some kind of factory treatment on it's 'screen and now I 
don't need it, but on the old volvo, I used it religiously!! It sells for about $7 at K-mart.

I also tried Fog-X to reduce window fogging, which works, but you need to keep it maintained a lot other wise your get streaks and such like which make it hard to see 
on a sunny day

Hi All,

can anyone help me in my quest to obtain a printable IR sat. image of
Aust., 00UTC, 4th June, 2001? This date falls in between BOM 7 day
archive, and longer-term archives which are unavailable until the end of
the month,

Thanks for any assistance,

I guess I should do a quick reply to this although with accounting theory
and accounting ethics exams this week I am extreemly busy and i'm only
commenting after a very limited look a data from this morning.

Front should cross Victoria tomorrow afternoon and cold air should extend
throughout by Wednesday midnight and snowfalls on the alps should start
sometime around midnight and then the altitude snowfalls start at should
drop rapidly and IMO bottom out somewhere between 400-600m (in Victoria).
Following the front we should see showers, local hail and thunder and
possible sleet in the suburbs of Melbourne (given the timing of the coldest
air to be early thursday morning and coninciding with the coldest part of
the day i think this is quite possible).  Overall snowfalls for Victoria:
The areas between 600-1000m should see between 5-20cm of snow, 1000-1200m
should see some heavier falls of up to 30cm and I think the alpine resorts
(inc. NSW ones) could see as much as 50-60cm from Wednesday night until late
Friday (maybe continuing very sparesley friday night) with the heaviest
falls being on Thursday.  I wouldn't be surprised to see some road closures
due to heavy snowfalls and black ice.  The road through the Black Forest
will be a shocker on Thursday as will be the Black Spur and the Alpine road
(both ways out of Mt Hotham) and probably also the roads to Mt Baw Baw and
Donna Buang may be closed.  Enough from me.

Please remember that this is based on the model runs I saw this morning
(briefly) and also past experience with systems such as this.  Apologies for
not covering NSW but i'm sure you can get an idea of what's going to happen.

Regards,

Andrew McDonald

<DIV><FONT face=Arial size=2>Why do I say this... well today's forecast for

my thermometers were hovering around 8.5 to 9.5 degrees. there were showers on

hi,

The speed of light is absoloute in any reference frame - so it would only go
'c', regardless if measuring relative to the car or an inertial frame -
confusing? it should be, this is Einstein's theory and is the route of why
time and space diallate - ie the only way to explain why the light can be
going the same speed is that time/space must change between the reference
frames.

this is a really simplistic view but if your interested, there are some good
books around.

On the topic of a cross-wind with regard to measuring the wind speed
relative to a moving car, the anemometer does not know direction but rather
resultant wind. Hence, i would suggest that the vector subtraction of the
two 'winds' would give the anemometer reading.

Cheers, Lyle

Hey all

I went on a bit of a chase yesterday and took a few snaps of the chunky 
Cu that developed, some nice showers occurred, reaching red on radar.

Here are some scans

Some very (more than) welcome rain has fallen here in the last 24 hours. I
have received more rain this morning than I have recorded for all of last
month. At a glance most places around the North East of Vic have done pretty
well out of it this time with light rain still falling. 26.4mm since
yesterday.

theoretically, you can't travel faster than the speed of light - note that
even Einstein doubted this but nothing more has ever been discovered.

But, if you were travelling near the speed of light (c), then, in your
reference frame, it would appear as though your headlights are acting
normally, going away from you at 'c'. Though, if you were travelling that
fast, i would be much more worried about diffraction and stuff like that,
another topic all together.

cheers, lyle

That's what I figured, and why I was wondering where vectors came into it.

I was near Mango Hill looking West. The cloud had cirrus-like stuff curved 
over the top of it, there were several in the area that had similiar looking 
features. It was a small Cu, but with a bit of vertical growth. So I would 
say an updraft had punched through the Cirrus. It looked to be over a farming 
area, so could the updraft have been a thermal?

So what should I call those wall-like lowerings on showers or storms that are 
followed by heavy rain drops.

I saw one good one of these once. You know the storm that had the tornado in 
the valley? When that came over my place the wall cloud was absolutely 
churning. Bascially the wall cloud was moving up into the cloud, but 
condensation was forming at the bottom of the wall cloud, so the wall cloud 
still stayed there. The must have been a huge updraft there. Is this a 
correct assumption? Also the storm last year, there was a huge 500ft high 
shelf(?) cloud in front, followed by nothing much of a storm. Ben Quinn saw 
this one from the hornibrook bridge. Was that a shelf cloud?

Yeah, well thats what I am trying to gain. I would like to try and get out 
for a chase or two this summer, or at least help someone out with SMS 
updates, so I figured I better make sure I know what I'm talking about by 
then.... :-)

I did this in grade 10. That's why I was hoping to cheat and not have to 
worry about the vectors.

> i) please define vector

A vector is a quantity that has both direction and velocity. Like you drivin 
north at 60kph.

> ii) please define scalar

A scalar quantity only has a value. No direction. Like temperature.

> iii) please could we have a couple of examples.

See above. Next we need someone to start crossposting to the maths_geek list 
and then we will never be the same again.... :-)

Well I think it would be cool looking to have on my car, even if it doesn't 
work! At least the other chasers would recognise me. But that other pitot

That's a good idea. Just means I have to look stupid and go into a kitchen

In any case I would still be able to use the device when I'm parked.

Damn. I was near there earlier in the day, but it was sunny then. I'm

Bussie,
The light will curve back over the bonnet and strike dead set between the
eyes. Blinded you will drive straight into a supercellular tornado (or maybe
a black hole) and punch out in a parallel universe.

Hi,

To obtain the relevant instruments for measuring the wind speed in the car
(apparent wind),true wind and direction, Try a ship chandlers that deals
with racing yachts, as they have been using the above instruments for
donkey's years, prices range from about $600 on up to what ever you want to
spend, they should be able to be calibrated to take into account  the higher
speed of the car.

What he is talking about is a pitot tube, but it has to be very close
to straight on to the relative airflow or it will not work.  If the
pitot tube was mounted in a wind vane so that it could rotate to the
relative wind, all you would need would be an electronic differential
pressure sensor and a synchro to provide the angle output, feed those
two data streams to a laptop also reading the electronic car speedo
output, and the magnetic heading from a flux gate compass, and with a
little software, bob's your uncle.
Personally though, for a cheap and nasty but effective solution, I
would be more inclined to use a hand held brunswick tube array.

Then there's egg-cups, communion cups from church, Turkish coffee cups, 
Chinese tea cups, or simply cut ping-pong balls in half!

Hi all,

In a reply to my own post here I just want to make some brief adjustments to
that forecast below based on this morning's model runs (of which again i
have only looked at briefly).

I'll leave the levels of snow and the amounts for the lower levels but for
the alpine resorts (escpscially Mt Baw Baw) I'm going to increase the amount
of snow from 50-60cm to 70-80cm.

Regards,

Andrew McDonald

More to point...

If I am chasing a supercellular tornado at 0.8 c and you are chasing from
the opposite direction also at 0.8 c, (lets assume the tornado is stationery
in the reference frame and lifts at the critical moment), then what speed do
you pass me at?????

At least we're all getting a bit of mileage out of this one while waiting

What happens then if I'm travelling faster than the speed of light and I

I'd be more worried about running into someone... Your brakes may overheat
slowing down from light-speed to stop.

Not to mention the Doppler shift would make the traffic lights all weird
looking. Does purple mean go, or was it the aqua one?

G'day Andrew,

Im sorry i don't have time to answer your email in detail now, besides, I'm
probably not sufficiently skilled to do so :)
I can recall Laurier saying once that 850 temps are also important when
getting a grip on predicting snow fall, not just the thickness. The 850
temps are around the 1500 metres asl mark so I use this as a guide for
places in my area that are approaching 1400 metres. That is, Mount Trickett
is 1362 metres, so that is about a degree or so warmer than the forecasted
850 temps as a rough guide. Make sense? Probably not! lol

     Hey guys,
        I remember last year there was a forecast for 32C or so in Sydney's 
west and it got to only 15C, today was the opposite with 14C forecast last 
night for Richmond today, and the top there reaching a balmy 23C!
Cloudy but not a drop today.

P.S, if i'm sitting 200m behind a cop in Tamworth, who's doing 70 in a 60 
zone, and proceed to follow at that length at constant velocity to the radar 
in his car, what is the result?
Answer: the bloody bastard booked me for speeding (now being contested)

Don't bother.  The court will convict you.  Just because the officer
is speeding does not mean you can.  He "may" have had a valid reason,
ie, silent approach to an incident or whatever, you do not.  Save the
legal and court costs, and save the additional fine the magistrate is
likely to impose.

This is getting silly, so one may as well contribute I suppose.

Lets take the given conditions, ie, you were both doing 0.8C in
opposite directions towards the stationary tornado.  Hence, your
relative closing speed would be 1.6C with respect to each other in the
tornado frame of reference.  The tornado would see two grossly doppler
shift distorted objects hurtling towards it from both sides at 0.8C
that would scare the hell out of it (causing it to lift off perhaps
?).  Each of you in turn would be able to see the tornado as normal,
but would see each other as even more grossly doppler shifted and more
frightening than the tornado's view of both of you.

Upon reaching collision point, a "humungously" inelastic collision
would occur.  Since E=mC^2 you would have an instantaneous
(mathematically) creation of 156% more energy than previously existed,
or deplete 156% of the previous combined mass into oblivion, (which is
impossible, since you only have 100% to begin with) or some
combination of both (because 0.8 + 0.8 = 1.6 and 1.6^2 = 2.56 =
256%).  Unfortunately, theory says matter can neither be created nor
destroyed, so, we have to keep 100% mass, so we give the tornado the
excess 156% as energy, or, perhaps, we could give it some combination
of both mass and energy.  Either way it gets boosted !

But if the tornado has jumped out of the way, then what ?  If it is
not there, it can receive neither mass nor energy.  Since we create
all this excess energy in the collision, (itself impossible, but to
continue) we need to create an event horizon to another frame of
reference into which to bleed the excess 156% of energy or some
combination of energy and matter.  In essence, you have created a worm
hole, or a black hole, into which one or part of both of you will
disappear, either in body or "enlightenment" or combinations of both
!  In reality, the "event horizon" has to be created by the collision
itself, to create a portal through which you acquire the 156% energy
for the collision (since it had to come from somewhere), and then give
it back, through the same (or another) portal, in the same instant ! 
This would be "far more exciting" than "any"  tornado you were chasing
initially !  (not to mention down right scary).

If on the other hand you play chicken and "just miss" a collision in
the first place, (boy that was close !) and past each other close
abeam, you would still have an unexpected risk of collision (and you
will loose !) because your masses have increased from rest mass due to
your speed by 1 / (0.8^2) = 1/0.64 = 1.5625 = 56.25%, which, in turn,
creates an unexpectedly great gravitational attraction between the two
of you as you play chicken !  (remember the gravity equations, ie, g
is proportional to 1/d^2 remember !)  SO, in the final instants on
approach, as the "d" is rapidly diminishing towards 0, mutual
attraction is rapidly heading towards infinity, and you both suddenly
realise (if you are lucky, but too late anyway !) that you can not
avoid a collision no matter how hard you both try to swerve to avoid
each other !  The poor old tyres just can't handle it and you skid
together and "wham" anyway ! (RIP guys !).

Should you survive, Einstein would like a word with you.

Hi Lindsay and others,

Yep - I have also taken this into consideration and now that my first exam
is well and truely over I can concentrate more on thie event.  AVN has 850
temps over Melbourne of -3.5C tomorrow morning and 850 temps of below -2C
are forecasted by AVN and other models as far N as Sydney (and Blue
Mountains) by tomorrow evening.  Further to this, AVN also suggests that
sub-zero 850 temps heading as far north as the Stanthorpe area by Friday
night.

Also of interest is the BoM forecast of snow down to 900m.  I'll be
interested to see if this changes tomorrow.

Hope this helps.

Regards,

Andrew McDonald.

Yep. Its true there was footage of a waterspout off Russell Island in
Moreton Bay. This area is a little too far south of where I am to see, but I
am not particularly surprised given the type of weather over Moreton Bay
lately. Although I couldn't spot any local landmarks to prove the footage, I
see no reason why anyone would try to fake it.

By the way the footage was a genuine waterspout - no doubt. No possibilities
of any mistakes. Does anyone know anyone at Channel 9 to be able to contact
the clever devil who shot this footage ?

Simon

In relation to the BoM/NMOC  500hpa height/wind/temp. chart, what do the

they small-scale height/pressure anomalies within the general flow?

2 Has anyone heard of or seen a "white rainbow". A friend of mine said he
saw it on morning before dawn around 5 am in Warwick. The w was showers, but
the moon was visible at the time. Any ideas? It apparently looked justy like

Go for it Rune.....that cop must've been in a bad mood....I've followed one
just south of Broadwater (25k's sth of here) doing 120 km/h.....the only
reason I coudn't keep up with him is because the double lanes finished &
there was traffic coming the other way.....I reckon he was doing about

g'day Adam,

 Can't help you with Q.2, but the halo effect of the moon is generally due to
upper-level cloud, in particular, cirro-stratus.  The old saying that a halo
around the moon is a predictor of rain has some credence as cirro-stratus
build-up is generally indicative of an approaching cold-front,

Hi Greg and Adam,

A "white rainbow" at 5am, sounds like a fogbow to me!

Hi Greg,

If you're looking what I think you're looking at, H and L should signify
high and low pressure at 500mb.  (Ie, upper level highs, and upper level
lows).

I've had my experience of high flying cop cars go by me for no real
reason (other than late for dinner...but I can't really make any
assumptions) - and I have also followed a few in my time :)

I personally would have used the excuse "My speedo is playing up, so I
thought if I followed a police car, then I should be right until I could
get it checked!"

Further to Greg's post, there is a website that has a step by step
explanation of all the features of aerological diagrams. I was looking at
the BoM's diagram the other day and while I understand some of it, I'm a bit
rusty with the rest. Can someone please point up where the above website
is..thanks (I forget whose it was)..

Hi Simon

I contacted Channel 9 early this morning and they said they would pass on my
contact details when they dropped the tape back to the guy today.  Hopefully
he'll be willing to donate a copy of the footage to ASWA and/or BSCH

Legally, the police have the right to break any law they see fit to break "in
the course of duty" and "when reasonable".

They do not have to display lights or sound a siren if they feel it will hamper
catching a criminal.

Sad but true.

I saw what I would describe as a white rainbow last Sunday morning.  I was
driving in heavy fog, the end of the rainbow was beside me.  The time was
about 8:30.

Very unusual rain here in Alice Springs at the moment. Looks like the end of
this rain period, in which we got 36mm. Yulara got around 148mm, which has
to be some kind of record for the month of June. I've been living here for
some time now, and although we have had cold periods that involve some light
rain, I have never experienced a good fall of rain in June. The Finke Desert
race for bikes and buggies was run over the weekend, which sees about half
the population of the town go bush down south and camp along the race track
between Alice and Finke, and small community near the S.A. border. Luckily I
opted out for this year. The road would have been and absolute quagmire for
all of the campers to return on, and many a muddy car was seen in town on
Monday night. Anyway, I would be interested to see how many, if any records
were broken for around here and Northern S.A. Good to see Adelaide getting a
good drenching for the winter, after a very hot summer.
Cheers,
duncan

Hi,

The halo around the moon from my understanding is caused by the moonlight 
being refracted by the atmospheric ice crystals at a certain level

The white rainbow  I have seen before and also I had mentioned to this 
list. It occurred due to the moonlight - usually just after a setting full 
moon scattered by the raindrops similar to a rainbow only during the 
darkness hours ie no colours are made out by the naked eye

Not a fogbow Anthony   it happens when moonlight is refracted by a shower 
that obviously has some clear skies to allow some of the moonlight through. 
It looks similar though perhaps a little sharper from memory.

HI all.. Have to agree with Bussie on this one. I have been in Wodonga
since Thursday last week. It poured from Young to Wodonga. It basically
was raining the whole time in Wodonga. Drove back to Bathurst today, 
left at 12.30pm, no rain until I arrived in Cowra. Bathurst had rain
on and off all day I was told.  Very cold in Bathurst now with temp at
6.1 deg. Quite a difference compared to Wodonga/Albury. 
Im now on call for work, so maybe very interesting if it happens to 
snow around Oberon,Lithgow area. 

Please watch my snow report site where i will state any road closures
at the time.  

http://www.nia.net.au/~davidkc/snowreports.html 

Thanks 
Dave
Bathurst.

Hi Keith, Greg, Anthony

I think it might have been mine - it was on the NEMAS site but it's since
closed down.  I've uploaded to here for now :

http://www.bsch.au.com/temp/500mb/index.htm

I'll leave it there for a few weeks

For some reason the long wave trough example has dissapeared, and i can't
find a good clear one in the current model runs.  Try looking at the long
wave ridge example and turn the map upside down :-)  If you really get stuck
email me and i'll whip something up in a paint program

Also, It was written a long long time ago and there are probably a few
errors, especially in the part about vorticity... i haven't got around to
updating it.  Having said that there should be enough there for a general
understanding of what's what

Hi Adam,

I have a picture of a coloured "rainbow" around the moon, I also took images
of the white "rainbow" too but still in the camera :(

The coloured image was taken trough Cirro-stratus cloud at the time, looked
quite impressive.

http://sastorms.virtualave.net/temp/moonbow.jpg

the bright object to it's Right is a reflection of the bright moon through
the lense.

I know slightly off topic...

regards

Andrew

saw it on morning before dawn around 5 am in Warwick. The w was showers, but
the moon was visible at the time. Any ideas? It apparently looked justy like
a regular rainbow except it was white.

Aerological diagrams are the life blood of glider pilots.
If you dig through these you should find what you need.

To start with the basic theory, try these:
http://www.booty.demon.co.uk/FAQ/subindex.htm
specifically,
http://www.booty.demon.co.uk/metinfo/thdyndia.htm#General

Then go and get RAOB at:
http://www.raob.com/

And then move on to the practical use of aerological diagrams at:
http://www.mindspring.com/~gmlawler/ses/stormlift.htm#LIFT_INDEXES
http://www.mindspring.com/~gmlawler/ses/storms.htm
http://www.isrv.com/~lhuffman/fore.htm
http://www.mindspring.com/~gmlawler/ses/stor_eck.htm
http://www.scottz8.fsnet.co.uk/

Then, you will be an expert.

PC

actually - no. If the wind is has a component in the same direction, you
will get a slower wind speed.

i think at that point brakes arn't going to matter, whatever object you come
near, your simply going to diffract around them, probablisticly go through
them or change time so it's not there anyways :)

awesome reply! Though, i'm not sure about the collision at 1.6C due to the
time/spcae change between there reference frames.

Quite a cold start to the morning here sitting 5.9 at present and a pretty
gutsy (gusty) WNWerly at present which has produced a wind-chill down to -3
at 6.15am this morning.
This has probably been mentioned before but does snow show up on the radar
and is it different colours for heavier snow etc. Just wondering.

That's one big call Andrew! My thoughts are that it will be too dry for the
major resorts to get much more than about 20cm, but Lake Mt, Baw Baw, and
possibly parts of the snowies will do better. It does look like a classic
system for leaving Baw Baw with more snow than it "big brothers".

Yea, I often scratch my head at some of the official snow levels, but most
of the discrepancy (I think) lies in the definition of snow, and that the
forecasts are chiefly for the "average" rather than the extremes in space or
time. Low land "weather nuts" like us who only see the odd wet flake in our
back yard about once in two years would probably define this as snow, while
the average person would probably not notice the flakes. Strictly, the
definition of snow is "Precipitation of ice crystals most of which are
branched", which would seem to leave the cut-off very close to the zero
degree isotherm (minimal melt), while evaporation cooling down drafts etc,
will see mixed frozen precipitation (sleet) falling 100-400 metres below the
freezing level. I would like to see "sleet" or rain/snow mix included in the
forecasts, but socially and economically there is probably not much to be
gained by this increase in work/text length, and most forecasters are snowed
under anyway.

As for the "local" (and I suspect currently unpredictable) variations, the
May 2000 event was a classic for this, with snow lying thickly on the Sunday
to the 150m level on the hills around Yarra Glen, but at the same time the
Dandenongs were clear of snow (only ~20km south) upto at least the 500m
level. Similarly across the Black Spur, the western snowline was around 500m
on the Monday, while to the east this was near 150m. 

Cheers, and happy WX watching.

David.

Very brisk here in Wycheproof this morning.

Sunny at the moment though.

Grand total of 8 mm. yesterday.

As I understand it, the lake is completely dry, although there is 
still deep mud in its lowest parts (as a group who tried to run 
across it over the weekend found out).

The only time in the last ~50 years that it has been dry has been
for a few months in 1982-83. The lake has a small catchment and is
extremely sensitive to changes in evaporation, as well as inflow; it
also seems to respond to rainfall on multi-year timescales (for example,
it came nowhere near drying up in the very dry year of 1994).
It was dry for much longer periods at various times prior to 1949.

The highest I've seen it was in the 1988-91 period when it was quite
close to the main road, although I have very vague memories of it
being at a similar height around 1976 (my recall isn't that precise -
I was five at the time - but given the rainfalls of the mid-1970s it
makes sense).

I don't know much about the history of land ownership on the lake bed -
presumably the land was originally allocated or possessed at a time 
when the lake was dry and those property boundaries have remained
ever since. You'd be a tad unimpressed if you bought the southeast
(deepest) corner in 1949 and had only had six months' use of the land
in fifty years....

I have just seen some weird clouds north of Brisbane. They are small to 
medium size Cu's on top of smoke from a bushfire. The smoke seems to almost 
be part of the cloud and it looks really wierd especially the way the light 
goes around it. Someone mentioned Pyrocumulus ages ago. Could this be it?

Also since this morning I have seen straight and not very wide bands of 
cirrocumulus go over. Why is there more than one band? If a front was passing 
I would expect one band, but why 3 or 4?

Finally, it seems some people who must compulsively thoroughly read every 
email they recieve from this list had their sensibilities offended yesterday 
when I posted to the list in response to a few replies to a message. I 
sincerely apologise to these people. 

Also #weather on Austnet seemed to be attacked by someone yesterday. It 
wouldn't suprise me if they did it because I was there or something and the 
issue above. To avoid this I am no longer using this chat group. I will also 
put all replies to this mailling list in one single message at the end of 
each day. This message will be over 50kb of confusing replies to dozens of 
different messages. Hopefully the compulsive readers will be able to figure 
out what is in reply to what, or maybe even better - actually skip the 
message. Thanks,

Hi David,

I saw some Pyro Cu yesterday in the same direction, probably from the same
fire you saw them above this morning.  There has been no shortage of them
lately - up to a week ago i was seeing them several times a day for weeks at
a time! One of the best ones was :

Definately the hardest updrafts i've ever seen in a Pyro Cu

Very brave call Andrew.  I am no forecaster of note, but the air up
there is way too dry, in fact, if you look at the sonde traces (see
below), you will see a definitely drier air mass below 500mb than
yesterday has moved in.

the Oberon area. Has there been any sleet/snow in that area today,
Thursday?

I would say probably not at this stage.

Temps around this part of the world have been a tad too warm I think,
and it's been quite dry (in Taralga the temp has ranged from 5 to 9
during today which has been similar to Orange and colder than Bathurst).
We had snow clouds (bearing rain) around this morning but they soon
dried out to plain jane cumulus and apart from some sago earlier have
not shed a drop!

There are some scattered echos on the radar at the moment heading NE
from Wagga which might indicate an area of moister air but it might
still stay too warm. AVN indicates that unlike what was expected
yesterday, thicknesses will probably not go sub-535 over the Central
Tablelands but then the elevation of the area surrounding Oberon and the
onset of night might make up for that.

Still very dry at the moment though.

Andrew.

Just before 4:30 pm the temperature dropped to a little below 4 degrees
& we had a good fall of sleet, hopefully there is more to come!

It was late autumn, and the Aboriginal on the remote tribal lands
asked their new elder if the winter was going to be cold or mild.
Since he was an Aboriginal elder in a modern society, he had never
been taught the old secrets of dream time forecasting, moreover, when
he looked at the sky, he could not tell what the weather was going to
be.

Nevertheless, to be on the safe side, he replied to his tribe that the
winter was indeed going to be cold and that the members of the village
should collect wood to be prepared.

Also being a practical leader, after several days he got an idea. He
went to the solar powered sat phone booth, and called the BoM asked,

"Is the coming winter going to be cold ?"

"It looks like this winter is going to be quite cold indeed," the
Meteorologist at the BoM service responded.

So the elder went back to his people and told them to collect even
more wood in order to be prepared.

A week later he called the BoM again.

"Is it going to be a very cold winter ?"

"Yes," the man at the BoM replied, "it's going to be a very cold
winter."

The elder again went back to his people and ordered them to collect
every scrap of wood they could find.

Two weeks later he called the BoM again.

"Are you absolutely sure that the winter is going to be very cold? "

"Absolutely," the man replied. "It's going to be one of the coldest
winters ever".

"How can you be so sure?" the elder asked.

The BoM man replied, "Because the Aboriginies are collecting wood like
crazy."

No Worries Peter, never really liked him anyway.

Onto other things more weather related, had some nice Antarctic weather come
through Melbourne today, including a nice thunder storm that hit while I was
sitting at my desk at work with my video camera next to me, think I could
convince the person on the phone that I really had to go!!

Also saw an Anvil this afternoon on the SE side of Mt Dandenong that looked
like Devils Tower from Close Encounters, only upside down.  Really strange,
never seen one like that and naturally couldn't find a decent spot to get a
picture of it before the MLC took over.

About a 45 minute period of sleet that was just turning to snow before
the cloud cleared (!!!) has just finished in Taralga. It would have
fallen as snow in the surrounding hills as it got down to and is still
1.2 here.

Always the way here - just about to snow and they snatch the clouds
away, back to the western side of the range. I expect snow is falling in
Laggan and Crookwell etc...

Hi Peter and all,

I just checked the AVN and it seems that there is a lack of moisture in 
this system for the heaviest precipitation on land. I also think that in 
the Blue Mountains, it will be the more exposed slopes around Oberon that 
will juice out most snowfalls due to the orographic effects. Tomorrow night 
is probably the best chance of some reasonable snow although the coldest 
air is expected northwards. So it should be interesting to see what happens 
on the Northern Tablelands with this system later tomorrow as well again 
with orographic lifting.

Cheers.

Jimmy Deguara

 Seems like SE Aus is finally getting what NZ's been experiencing on and off
since mid May. But we're now having a break from winter, with mild north to
northwesterlies (15 C max in Christchurch today). But this reprieve should
only last until Sunday, then a another cold southerly outbreak should
arrive.

<DIV><FONT face=Arial size=2>Hi everyone,</FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>Well - how could I resist.&nbsp; I woke up this 
morning at 6:30am and within 30 seconds of standing at the window was greeted by 
a big FLASH to the south, then 10 seconds later FLASH again!&nbsp; I loaded up 
the radar, sat pics, obs and forecasts and was out the door heading to the south 
eastern suburbs with an STA out for damaging winds.&nbsp; I headed down to 
Mordialloc and spent a few hours watching cold air Cb's to my south and south 
west before getting a few soft peices of hail while parked at the beachfront 
carpark at around 9:45am as well as wind gusts to 25knts and wind chill 
temperatures hitting -4.9C.&nbsp; After this cell passed overhead I followed it 
east on my way to Mt Dandenong - it was time to check for snow up at the 
observation tower.&nbsp; I captured some great mammatus along the way on the 
back side of that cell mentioned above.&nbsp; Half way up the mountain I drove 
into the cloud and by the time I had reached the lookout visibility was down to 
about 25m.&nbsp; A quick check with the Kestrel showed a temperature of between 
2C and 3C and with winds gusting up to 15knts, the wind chill temperature 
bottomed out at -8.9C!!!!!!!&nbsp; I called Anthony Cornelius to get a radar 
update and suire enough there was a nice cell headed my way.&nbsp; Within a few 
minutes light rain was falling.&nbsp; This soon turned to sleet and the 
temperature dropped to about 1.5C.&nbsp; After intermittent sleet and rain for a 
few minutes the hail started.&nbsp; Only lightly at first but within a minute it 
was TORRENTIAL to say the least.&nbsp; Of course the video camera was running 
overtime, getting footage of the hail falling and suddenly 
FLASH.....CRACKBBBOOOOMMM (although somewhat muffled for some reason).&nbsp; 
Well - if I wasn't excited before hand I certainly was now.&nbsp; The hail kept 
falling and another close lightning strike followed by 2 other more distant 
flashes/rumbles.&nbsp; As the hail stopped a brief flurry of snow fell&nbsp;(for 
about 20 seconds) and a distant rumble of thunder echoed across the mountain top 
- MY FIRST THUNDERSNOW!!!!.&nbsp; The carpark and surrounding areas were white 
with hail (some people may've mistaken it for snow).&nbsp; I was ecstatic.&nbsp; 
The cell and cloud cleared off to the N and I was out playing in the hail and 
taking photos and video of the cell which displayed some great structure with 
the flanking line and anvil and mammatus.&nbsp; What a day!&nbsp; Witht he hail 
cover, the temperature was hovering between 1C and 1.5C.&nbsp; Another cell was 
brewing down to the SW but I was intent on heading up to Kinglake for another 
check of conditions.&nbsp; I headed off from here only to make it half way down 
the lookout road and Robert Goler was heading up to the lookout in the other 
direction.&nbsp; A quick U-turn saw Robert and I meet for a 3rd time of 
unexpected chaser convergence within six months.&nbsp; We headed back up to the 
top to watch the next hailshower come through.&nbsp; This one was a little 
different with sleet starting straight away and within a few minutes, big, fat 
snow flakes became mixed in with the sleet.&nbsp; Intermittently, the snow would 
take over totally as these flakes just floated down on the breeze - sometimes 
lasting nearly a minute.&nbsp; The ground was far to wet for it to settle yet it 
was still very clod as the hail from the previous shower (over an hour before 
now) was still piled up in corners and on the grass.&nbsp; The snow and sleet 
stopped again and Robert and I headed up to Kinglake via Yarra Glen.&nbsp; It 
was only 4.5C here and were hoping for some more hail or sleet action.&nbsp; We 
got some lunch here at about 3pm and as we were about to leave a big flurry of 
snow pellets (though i'll call it sleet) fell for about 30 seconds followed by 
some more traditional sleet.&nbsp; After another call to Anthony, we decided to 
head back down to the eastern suburbs and then out to Mt Donna Buang.&nbsp; On 
the way a quick stop at Yarra Glen saw us in another hail shower.&nbsp; It was 
getting a little late for me (i'm supposed to be studying today) so I turned 
back and headed home (again via kinglake - hoping for more sleet or hail) and 
Robert continued up to Mt Donna Buang.&nbsp; I neared Yan Yean on my way home 
and saw a nice little Cb to my weat and I couldn't resist.&nbsp; I pulled 
another u-turn and headed N for a bit before heading W to intercept.&nbsp; I 
drove into the rain and hail and then sat under a nice little updraft base which 
was fairly turbulent and interesting.&nbsp; Hail kept falling for most of this 
time. The cell eventually moved out of chasing range and I watched as it moved 
away showing some nice structure and a chuncky lowered base.&nbsp; I think it 
was my 6th hail enounter for the day.&nbsp; I also encountered sleet 3 times, 4 
rumbles of thunder with 2 being flangs and a partridge in a pear tree.&nbsp;

Hi David,
    Yes indeed these clouds were most likely Pyrocumulus. The processes
involved (if you were wondering): An extensive wild fire or bush fire (like
the one you observed) produces vigorous rising air currents and a large
quantity of water vapour that is released by the air and vegitation during
combustion. The rising air lifts the water vapour to a level (LCL) where it
condenses and forms cumulus clouds that "ride" above the fire. The bases of
these clouds are usually difficult to discern as they are masked or hidden
by the smoke. Pyrocumulus have the capability (depending on the atmospheric
conditions) to develop into cumulonimbus incus (thunderstorms).
    As for the narrow and straight lines of cirrocumulus, depending on how
far apart they were or the size of them, I would have to guess cirrocumulus
undulatus. These are typical before a front or pre-frontal trough. They form
when atmospheric waves generated by wind shear (associated with the lifting
of an air mass over a horizontal distance) produce narrow "ripples". Another
way of looking at this phenomena is by picturing one layer of air sliding
over another layer moving at different speeds or directions. Just a little
info for whoever was interested. Cheers.

Thursday 9:30pm  (my last post took over an hour to get here...) Temp 1.5C
6/8 st. cu.

Hi jimmy,

I can see your point. There isn't a lot of moisture at the moment. Orange
has had some precipitation tonight whilst the temp has been in the 1.5C
range with negative dew points, so I presume that is snow and even Bathurst
is showing light precipitation with a similar temp. As usual here in
Blackheath, we wont get much from this unless the winds turn more south
overnight or tomorrow. There just isn't enough moisture, IMHO.

We had a light flurry of snow this arvo for a few minutes and some sleet and
a few more flakes tonight but very little, so far.

Hi guys,

Three of us hit the lookouts to the west of Blackheath at lunchtime and
there was precipitation falling but perhaps not reaching the ground in most
places. I'm sure there would have been some rain/sleet falling over the
Mount Trickett area (south of Oberon at 1362 metres) as there was low cloud
and what looked like rain/sleet there. It was around 6C here in Blackheath
at that time so I doubt there would've been much snow, if any out that way.

However as we speak, i am surprised to notice that the temp at Mount Boyce
is now 3.8C and falling. Hmmm, there might be some sleet/snow south of
Oberon as we speak. From what I can see (and have been told), the coldest
air should arrive during the night and into early tomorrow. There should be
some snow out that way tomorrow. I'm heading out there early tomorrow
morning to get there by sunrise, hopefully.

It's now snowing in Blackheath! at 4:22pm

<DIV></DIV>&gt; 
<DIV></DIV>&gt;It was late autumn, and the Aboriginal on the remote tribal lands 
<DIV></DIV>&gt;asked their new elder if the winter was going to be cold or mild. 
<DIV></DIV>&gt;Since he was an Aboriginal elder in a modern society, he had never 
<DIV></DIV>&gt;been taught the old secrets of dream time forecasting, moreover, when 
<DIV></DIV>&gt;he looked at the sky, he could not tell what the weather was going to 
<DIV></DIV>&gt;be. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Nevertheless, to be on the safe side, he replied to his tribe that the 
<DIV></DIV>&gt;winter was indeed going to be cold and that the members of the village 
<DIV></DIV>&gt;should collect wood to be prepared. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Also being a practical leader, after several days he got an idea. He 
<DIV></DIV>&gt;went to the solar powered sat phone booth, and called the BoM asked, 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;"Is the coming winter going to be cold ?" 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;"It looks like this winter is going to be quite cold indeed," the 
<DIV></DIV>&gt;Meteorologist at the BoM service responded. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;So the elder went back to his people and told them to collect even 
<DIV></DIV>&gt;more wood in order to be prepared. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;A week later he called the BoM again. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;"Is it going to be a very cold winter ?" 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;"Yes," the man at the BoM replied, "it's going to be a very cold 
<DIV></DIV>&gt;winter." 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;The elder again went back to his people and ordered them to collect 
<DIV></DIV>&gt;every scrap of wood they could find. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Two weeks later he called the BoM again. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;"Are you absolutely sure that the winter is going to be very cold? " 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;"Absolutely," the man replied. "It's going to be one of the coldest 
<DIV></DIV>&gt;winters ever". 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;"How can you be so sure?" the elder asked. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;The BoM man replied, "Because the Aboriginies are collecting wood like 
<DIV></DIV>&gt;crazy."

Hi all,

A few weeks ago Winter seemed to have lost its way but it's back
now...14.6C here at 9:45am - brrrrr!  SW'lies with near zero degree
DP's.  Does anyone know what the current average highest Brisbane max
for June was?  If so, do they know what the current June max for
Brisbane is?  (Blair, anyone?)  We've had lots of above average maxes,
and I'd be thinking that currently we are exceeding the average highest
max, and would be interested to see what sort of temperatures we'd need
over the next 2 weeks to break that...

All,

It seems there was a few very light flakes here overnight as there was
an almost undetectable layer of white on the surfaces outside
thismorning. It was either snow or very heavy frost.

Minimum of -1 here overnight, still 3 in the shade at close to 11AM.

There are a few scuddy bits of cloud comming over from the west which
means that there might still be a bit of sleet or snow at Laggan, but I
doubt it.

I suspect Lindsay and co. will have seen some light snow showers at
Oberon/Shooters Hill early this morning. I look forward to hearing his
report.

Andrew.

Hi Anthony,

According to the BoM site:  Brisbane Airport June highest Max is 28.3C and
the regional office (up to 1994) is 31.6.  Think there is little chance of
breaking that now...  Site doesn't have highest mean max tho..

Hi all,

A few weeks ago Winter seemed to have lost its way but it's back
now...14.6C here at 9:45am - brrrrr!  SW'lies with near zero degree
DP's.  Does anyone know what the current average highest Brisbane max
for June was?  If so, do they know what the current June max for
Brisbane is?  (Blair, anyone?)  We've had lots of above average maxes,
and I'd be thinking that currently we are exceeding the average highest
max, and would be interested to see what sort of temperatures we'd need
over the next 2 weeks to break that...

<DIV></DIV>&gt;
<DIV></DIV>&gt;It was late autumn, and the Aboriginal on the remote tribal lands
<DIV></DIV>&gt;asked their new elder if the winter was going to be cold or mild.
<DIV></DIV>&gt;Since he was an Aboriginal elder in a modern society, he had never
<DIV></DIV>&gt;been taught the old secrets of dream time forecasting, moreover, when
<DIV></DIV>&gt;he looked at the sky, he could not tell what the weather was going to
<DIV></DIV>&gt;be.
<DIV></DIV>&gt;
<DIV></DIV>&gt;Nevertheless, to be on the safe side, he replied to his tribe that the
<DIV></DIV>&gt;winter was indeed going to be cold and that the members of the village
<DIV></DIV>&gt;should collect wood to be prepared.
<DIV></DIV>&gt;
<DIV></DIV>&gt;Also being a practical leader, after several days he got an idea. He
<DIV></DIV>&gt;went to the solar powered sat phone booth, and called the BoM asked,
<DIV></DIV>&gt;
<DIV></DIV>&gt;"Is the coming winter going to be cold ?"
<DIV></DIV>&gt;
<DIV></DIV>&gt;"It looks like this winter is going to be quite cold indeed," the
<DIV></DIV>&gt;Meteorologist at the BoM service responded.
<DIV></DIV>&gt;
<DIV></DIV>&gt;So the elder went back to his people and told them to collect even
<DIV></DIV>&gt;more wood in order to be prepared.
<DIV></DIV>&gt;
<DIV></DIV>&gt;A week later he called the BoM again.
<DIV></DIV>&gt;
<DIV></DIV>&gt;"Is it going to be a very cold winter ?"
<DIV></DIV>&gt;
<DIV></DIV>&gt;"Yes," the man at the BoM replied, "it's going to be a very cold
<DIV></DIV>&gt;winter."
<DIV></DIV>&gt;
<DIV></DIV>&gt;The elder again went back to his people and ordered them to collect
<DIV></DIV>&gt;every scrap of wood they could find.
<DIV></DIV>&gt;
<DIV></DIV>&gt;Two weeks later he called the BoM again.
<DIV></DIV>&gt;
<DIV></DIV>&gt;"Are you absolutely sure that the winter is going to be very cold? "
<DIV></DIV>&gt;
<DIV></DIV>&gt;"Absolutely," the man replied. "It's going to be one of the coldest
<DIV></DIV>&gt;winters ever".
<DIV></DIV>&gt;
<DIV></DIV>&gt;"How can you be so sure?" the elder asked.
<DIV></DIV>&gt;
<DIV></DIV>&gt;The BoM man replied, "Because the Aboriginies are collecting wood like
<DIV></DIV>&gt;crazy."

Hi Michael

It starts at 7:15pm or so, but most people start turning up between
about 6:45pm and 7pm. When you get to the door at the street, press the
buzzer, or if that doesn't work, give my mobile a call on 0417685086.

See you there!

Hi all,

This is from my snowchase reports link on my home page, sadly, it will not
format correctly on the web page so I have pasted it to here for now, as is.
Enjoy.

June 15th:  A nice little chase out to the Oberon area today. Overnight
minimum in Blackheath was -2.5 which is quite cold for us, being high on a
ridge top.  Adam and I left Blackheath just before 6am as we knew by now
that this was a fairly marginal event and thought our best chance of seeing
falling snow, would be early. We were right.

Blackheath was quite clear, albeit dark when we left and it stayed that way
for all of the drive into Jenolan Caves although the strato cu. was
beginning to thicken ever so slightly. Frost appeared along the ridge top of
Mounts Bindo and Trickett, very thick in places. Soon, we were looking at
snow on the ground, not much, around 1 to 2cm. Rounding a corner on our
descent into Jenolan Caves, in the still limited light, we were confronted
with a large tree that had fallen across 50 to 60% of the road. I was only
doing about  40kph and am certain had I been doing much more, I would have
damaged the car considerably. I swerved to the right hand side of the road,
as gently as I could, and felt thankful there was no oncoming traffic.
Curiously, there was no frost on the road at this level when it had been
very heavy a hundred or so metres higher up. With heavy frost in this spot,
an accident was certainly on the cards.

Jenolan Caves was dead quiet, not a soul around. We cruised on through and
made our way up the other side of  the steep valley. The snow line started
again at around the 1000 metre mark, the level I had estimated the previous
afternoon whilst watching from Mount Boyce lookout near Blackheath. Snow at
Mount Trickett was in the 1.5 to 2.5 cm range with no snow observed falling.
At 1362 metres, its one of the best and easiest places to visit in marginal
snow conditions. Ice was thick here in  roadside gullies and puddles left
over from yesterdays rain. It could almost take our weight (Adam and I  are
in the 70- 75kg range) as we tested the thickness of the ice in various
spots.

After some mucking around in the snow, and breaking lots of gigantic sheets
of ice (I'd estimate it was around -3 or -4 degrees at this time)   we
headed for some developing strato cu. over near Shooters Hill. Snow lay on
the ground from about the 1100 metre mark here and thickened to about 2.5 to
3cm in places by the time we arrived at the settlement. We headed straight
for the radio tower site and enjoyed a great panorama of the area and also a
few flakes of  falling snow. After being stick behind a logging truck and
its associated articulated arm, beach buggy wheeled, log loading machine (It
was an amazing site)  for about 20 minutes we made our way into Oberon for
some tucker and a visit to the library. Seeing that nothing was brewing
weatherwise, we slowly headed home, making an extended stop at Mount Bindo,
taking in the sites at the top of this mountain. The last half a kilometre
to the radio summit was too steep and icy for the little excel so we hoofed
it up and arrived to a great 300 degree view of the Oberon and Blue
Mountains area, bathed in sunshine.

So, it wasn't a great snow chasing bust, still, it was an enjoyable drive
and we still had some fun in the snow.

Hi,
Our local TV station (NBN) just featured a story on the news showing a 
chaser in the US that was filming a tornado (Did the major networks have 
it?). Anyway, It started coming toward him and he had to get out of the way 
quite quickly!! Fortuneatly he seemed to escape but the local towns neraby 
sure didn't. Quite a number of homes were destoryed. It's down to 11 deg 
here now, I'm quite a wuss and have had the fire going since it was 18!! 
Tomorrow looks set to be quite cool.

This is a stupid idea I know, but could we subdivide the mailling list into 
several on the same server of course.

= aussie-weather - this would stay, for breaking weather events
= weather-newbies - this would be for people like me to ask questions and 
learn
= severe-weather - to discuss severe weather events, but not breaking news
= chase-reports - moderated, only chase reports

Then if you hate the clueless newbies you don't have to listen to them. Also 
could the lag time of this list be improved? Is this idea stupid? Also could 
the list/s be archived?

Steven, the best situation for snow on the Australia Alps is in moist
northwesterlies ahead of a cold front, with the temp low enough to
produce snow. Good alpine snow also falls in shower form when there's
a succession of troughs in a westerly stream. As the wind turns
further to the southwest, the stream usually dries out and only light
snow showers result. Deep cold moist southerly streams give very
little snow on the Alps, again because most moisture is deposited in
the mountains farther south.

An east coast low tends to dump most of its moisture on the coastal
ranges, so that the Alps don't receive good falls. On the rare
occasions that the temp on the southern side of the low are cold
enough to drop snow, there can be very heavy falls in the eastern
Southern Tablelands, on the Blue Mountains, and even on the higher
areas of the Illawarra. The Bombala/Nimmitabel area has received
metres of snow on occasions from situations such as these.

Cold pools moving across the southeast of the continent can produce
very heavy falls over a relatively narrow path anywhere from Tasmania
to southern Queensland, but they are usually brief, because the cold
pool tends to move at a respectable speed, often driven by a
substantial S to SW jet.

Hi Dave

Jeff Piotrowski took that footage, he took some good close up footage of a
tornado last year that was aired around the world.
http://www.stormproductionsinc.com/media/photo/brady2_ne_00.jpg
That is a photo of it..
He obviously has contacts in the TV industry to get his footage available so
quickly... The tornado on TV only destroyed 1 house and farm fencing etc
etc.... no lives lost... im surprised the footage made it on TV ... probably
cause it was close up and dramatic and it appereared he almost got himself
killed... He better be careful getting that close.. just asking for trouble
one.

Hi John,

It's the highest mean max I'm interested in - just interested in how we
are going in that respect...

Having the newbies on a separate list defeats the purpose of the list.
Besides if the list only contained newbies somebody would learn anything. I
really don't think anybody on this list is intolerant of newbies. Sure they
ask lots of questions but there are so many resources out there in internet
land that it only takes a few pointers in the right direction and anybody
can catch up real quick. So David, don't be shy about asking questions.

The list work well as a single group IMO.

I believe the forum is archived on the net somewhere. Jacob will point you
in the right direction.

Agree, it can be slow sometimes. Not a big deal for most things, but it does
make the list an impractical way to report on breaking weather.

I think the list is fine the way it is David, no need to change anything.
And I think Michael Bath archives aus-wx and and has it on the ASW site.

Hi David,

I agree with everyone else who's responded to this thread...THIS is the 
place for newbies...and oldbies...and everyone else!!!

Hardly a day goes by when something interesting, unknown to most or just 
plain informative doesn't gets posted.

I won't speak for anybody else but I find it the most tolerant, resourceful 
and just plain fun list I've ever been involved with.

Stick with it man, we'll all be better off!

Cheers,
Kevin from Wycheproof.

Nice reply, Peter! Now try this one:

When I fire my gun, bullets exit the barrel at 1400km/h. 

I fire my gun horizontally through a hole in the back of a plane
travelling at 1400km/h, at exactly 180 degrees to the plane's movement
and directly above an observer on the ground below. 

Given calm conditions between plane and ground, does the bullet strike
the observer?

Worth a go, Rune. Magistrates aren't always supportive of smart-alec
tactics or cops that book so close to limits that they waste court
time with the inevitable contest. Presumably, if he had time to stop
and book you, he wasn't in a rush to a domestic or other calamity.
With that excuse out of the way, the question is why was he doing 70?
It could be taken as entrapment. 

Unfortunately, you probably don't have proof that you were following
at constant velocity, and his legal out will be to say he was
travelling at the limit. 

Did he actually book you for doing 70, or were you doing an indicated
70 (i.e. 70 on your speedo.) Most vehicle speedos read 3 to 5% over.
The NSW Motor Traffic Act requires speedos to be accurate to within
10%. I believe that for this reason you are unlikely to be booked if
you're doing up to 10% above the speed limit, as it has been
successfully contested in the past.

Hi Laurier,

Just to add to this; If your interested in the quality of snow' the best
conditions i have seen are from westerlies - of course, the quanitity is
usually small so a nice wet dump ahead of the storm creates perfect
ocnditions - for australia atleast...

Hi,

<snip>
> Then if you hate the clueless newbies you don't have to listen to them.

I'm about to start a flame but this has bothered me for sometime - no not
the newbies but the people like David who actually think like this -
elitists bastards. I remember when I first joined this list, some two years
ago, I had NFI about weather. I had studied a bit of science and only just
got into weather so I had a lot of questions, some on very basic principles
that were not clear to me. Most of these questions were met with a few
informative responses but more often than not, disdain.

In the last two years I have learnt a lot about weather and a lot from this
list because it is a great forum. I still find some people counter
productive but being in a position now were I have some of the world leaders
in the science at my finger, it doesn't bother me anymore. My concern is for
the new people and the amateurs who have just as much right to try
understand all this as anyone else. Why do some science people have such a
thing against 'clueless' people? Sure, a little knowledge can be a damaging
thing but that's not why these people are like this. Are they worried
someone is going to come up with some theory they thought was there's or do
they just not realise that as scientists, they DO have a responsibility in
the field to further educate the next generation?

I personally would like to see a shift in the actions of some people on this
list. And if you don't want to answer a question, then don't, but don't be a
bloody asshole about it.

Cheers, Lyle

You think weather has found Brisbane?

After a few weeks of about 7C mins suddenly we get
Thurs          Min 7C
Friday         Min -1C   Frost
Saturday     Min -4C. As i write this email  at  751AM it is -3C outside and
was -4C outside at 7AM. Fog has lifted and there is still a very heavy frost
on the ground.  At last winter finds it's home. Can we break last years
lowest temp of -6C this year

Hello all,

For Melbourne/VIC people in particular...

I will be in Melbourne from Sunday 8th (pm) to Sturday 13th July, for the
teacher training week at the Bureau of Meteorology - 150 Lonsdale St and at
the Field Annexe at Broadmeadows.

http://www.schools.ash.org.au/paa/training.htm

I am one of the hosts/coordinators of this annual event - major thanks to
the BOM for opening the doors for this!

Anyone like to catch up with a QLD'er during that time, It would be great
to meet some of you folks...

Regards,

Sel

Hi Ben,

Great!

I was out taking shots of the same sunset - I noted the same strange
shadows cast on the cloud - from some small bits if cloud over the horizon,
perhaps?

Must admit you had a better vantage point than I  had - great pan shot!

Great sunsets up here just now - this is the best year for some time...

I have an Elimbah Sunsets gallery up at my web site, and about 16 more
recent shots waiting to go up.

Cheers,

Sel.

Hi Lyle,
------------------------
Sure, a little knowledge can be a damaging
thing but that's not why these people are like this. Are they worried
someone is going to come up with some theory they thought was there's or do
they just not realise that as scientists, they DO have a responsibility in
the field to further educate the next generation?
------------------------

I just thought I would respond to this as it raises an interesting point. I 
think in my view, this list comes closest to giving people a chance to 
understand people's concept of meteorology. However, your point on 
"protecting theories or let's just say original ideas" is great in theory 
but in this world of competition (science included) and people being just 
plain humans, ideas are being stolen so one must try and protect theirs 
until they have come up with new grounds. Businesses have security access 
to research areas to protect themselves from others stealing ideas. I 
recall my friend in computing suggesting something he learned from his 
lecturer: tell people always less than what you know in any field as you 
may find that people will otherwise try and take over!!! And believe me 
there are backstabbers out there always trying to beat you!!!

On the same token, some people pry on other people's websites and ideas 
trying to beat them rather than coming up with more original ideas and 
variety. But that's human nature. This is all sad really but you simply 
have to protect yourself and at the same time help others as much as 
possible is my philosophy.

Just thought I would share a little story from my days as a labourer. One 
person was employed in the company and I was asked to help this person 
learn the job and I would be posted elsewhere. My philosophy was to always 
train that people produced the right product in the way most comfortable to 
them (people are taller and work differently than others). Well his person 
from the first MINUTE tried to outdo me even with all my years 
experience!!!! He would do everything different to what I told him, tried 
to go faster and eventually when I had enough I asked to be moved. Even the 
labels on the boxes were all crocked... Well later I heard a mighty 
bang!!!! I had told him to pack boxes evenly which he did not and they all 
fell when he moved them about 15 metres away with street lights inside the 
boxes. The next lot of retrenchments, he was retrenched and never was asked 
to come back. The moral of the story: he tried to outdo me and clearly 
wanted to take over my job even to the extent I get retrenched. Well it 
didn't work.

Anyway, enough from me. I'm out. This list has survived and done quite 
well. I am though a little concerned about the ability of e-mails to be 
posted electronically rather than by pigeons:)

Cheers see you all at the meeting.

For the humor-impaired this is a joke:

- Coffee Shop with a view - Drive to a good vantage point in front of a 
storm, with a battery powered coffee maker and hot water in the back of your 
car. Set up a fold-up table and chairs, put out a sign, and wait for other 
chasers to come by. Sell hot coffee, tea, and biscuits.

- House demolition - Get a big truck, put the house on the back, then drive 
the truck into the path of an oncoming tornado.

- Road holding testing of cars - Drive on wet roads under thunderstorms at 
110km/ph. Also try driving through microbursts and tornadoes. Sell the 
information on how well the car preforms to the manufacturer.

- Toll road - Find a nice dirt track that links two roads frequently used by 
stormchasers. Set up a boom gate at one end, and charge a $2 toll for use of 
the road by stormchasers.

- "Twister" Tour - Convert your car to run by remote control, then sell seats 
to "Twister" fans. Drive the car as close to a tornado as you can. If they 
pay extra, organise a petrol tanker to fall in front of them.

- Information Line - Run a 1900 information line for stormchasers. Just 
listen to them on radio and talk to them on mobile phones, then sell the 
information to other chasers.

- Weather testing - Offer electronics manufacturers a service where you will 
put their product in front of a storm, on the top of a lightning pole. Sell 
the results back to the manufacturers.

- House repairs(for builders only) - Take all your building gear with you, 
then find a good storm, drive behind it and offer repairs to affected people.

Let's see if anyone can think of anything else..... :-)

David

Well, i don't think there are any people here like that. I always view myself 
as clueless newbie and when I say i saw I always append a question mark to 
indicate I think it was this, and ask if it could have been.

I'm not really in favour of that idea.  means more list to keep track of.

Maybe an "announcements" list for those who only want announcements (and
possibly chase reports) and this as the "general" list.  Under this system, I'd
like the stuff in announcements to be posted here as well.

Hi,

as someone who is still learning about the different weather patterns and
the jargon of weather, I use a very important button on the
computer....DELETE!!!!!  If I find the topic  of no interest or just way
above my head I either delete it or I file it for later referal.  It is very
easy to be critical of those who are trying to learn something new, and as a
teacher, I am very aware of the prior knowledge of most of this list, and do
not make anyone feel unimportant because they are interesed enough to admit
they are just learning.  That my friends takes some courage.  Don't knock us
because we do not have PhDs in Science, et al.  We are on this list to learn
from those who know more than we do.

I was not going to respond to this, but having read some of the other
responses, I felt as though it was worth it.

Carolyn

It should, because the vector sum of the velocities is zero.  All that remains
is a downrards acceleration due to gravity.

But don't try translating this into relativistic (near light speed) conditions.
Newtonian mechanics is only an approximation of Relativity that applies when
all relative velicities are much less than that of light.

It is best to keep the list as and where it is.

STORM CHASE & BREAKING WEATHER NEWS SUGGESTION :

Where speed is really important due to current and fast changing weather
situations, arrangements could be made to supplement this list with The
Weather Co.'s experimental list - if Mark Hardy etc. agree to it - it is a
very fast server with delays measured in seconds rather than hours.

Postings via the TWC email server could also be cross posted here so those
who do not wish to use a private company do not miss out on the excitement
current events, albeit sometimes a few hours behind real time.

Fragmentation of the aus-wx list is undesirable, and no doubt some have
concerns about using a private weather company as a list server, which is
why it is best to maintain the status quo, however there are times when the
speed of TWC's email server is clearly desirable.

Personally, I have no concerns about TWC, having found staff attitudes
towards the rest of us in the weather community as evident on the aus-wx
list and in private communications both supportive and informative.

Regards,
Carl.

I have some of Jeff Piotrowski's chase videos and it is obvious that he is
used to "asking for trouble."  I don't think he is going to change.

<P>Hi All</P>
<P>I tend to agree Laurier.&nbsp; Since I've been following snow events, over the last 15 or so years I've been in Canberra, the biggest dumps were a cut off low in 1987 (don't know where it was positioned) which delivered 1.5 metres to the base of Thredbo and around 1 metre to the Nimmitabel area over 2 days or so.&nbsp; The biggest prolonged event though, I think was a what I call a Katherine Wheel Low (I love how this list gives you the licence to be creative in describing&nbsp;weather systems: eg. the Donald the Duck cyclone; fetches of cold air and anything Clyve Herbert gets to describe!).&nbsp; This Katherine Wheel Low sat almost stationary in the Southern Ocean for&nbsp;over of a week and a half in late June, early July 1990, while&nbsp;a series of fronts spun off it delivering over 2 metres of snow to the Alps and 10 days of below 10 degrees C maximums for Canberra.</P>

<DIV></DIV>&gt;Cold pools moving across the southeast of the continent can produce 
<DIV></DIV>&gt;very heavy falls over a relatively narrow path anywhere from Tasmania

I might try and take on in the morning

further to earlier, my thermometer in 1C out so i should make that -5C for
last night with BOM saying it was -6C. Either way, its still a fair bit
below zero. Also, the fog lifted at 730 to come back at 830 to lift again at
930

Hi all,

Wow, the BOM's 4 day chart shows the high sitting above the Bight, well,
almost. Thank the Lord for small mercies :)

RE the function of this list, I think enough has been said so there's not
much more for me to add. Suffice to say, I am a bit of a beginner for sure
and have appreciated this list and the folk that contribute to it. My little
motto is to respect everyone and appreciate our differences. There endeth
the lesson for today. :)

For those that are interested, my June records are posted for the days so
far this month. They are a guide only but make for some interesting reading,
especially over the last few days. See my page link below and go to June
records, in the right hand margin.

Cheers,

Evening all,

I've put links to all of the MSC humour up on the main page next to the
road sign ("chasers nightmare").  Keep an eye out for "StormChasers -
Egypt Branch" to be added when they have a photo of ..... (btw, I'm not
kidding here!)

I'm looking for an artist to do some 'diagrams' to go with the following
(with many thanks to the author for this donation to MSC)  .........
have a read & if you would like to 'donate' diagrams or drawings, please
email or snail mail them to me.....


"Lets take the given conditions, ie, you were both doing 0.8C in
opposite directions towards the stationary tornado.  Hence, your
relative closing speed would be 1.6C with respect to each other in the
tornado frame of reference.  The tornado would see two grossly doppler
shift distorted objects hurtling towards it from both sides at 0.8C
that would scare the hell out of it (causing it to lift off perhaps
?).  Each of you in turn would be able to see the tornado as normal,
but would see each other as even more grossly doppler shifted and more
frightening than the tornado's view of both of you.

Upon reaching collision point, a "humungously" inelastic collision
would occur.  Since E=mC^2 you would have an instantaneous
(mathematically) creation of 156% more energy than previously existed,
or deplete 156% of the previous combined mass into oblivion, (which is
impossible, since you only have 100% to begin with) or some
combination of both (because 0.8 + 0.8 = 1.6 and 1.6^2 = 2.56 =
256%).  Unfortunately, theory says matter can neither be created nor
destroyed, so, we have to keep 100% mass, so we give the tornado the
excess 156% as energy, or, perhaps, we could give it some combination
of both mass and energy.  Either way it gets boosted !

But if the tornado has jumped out of the way, then what ?  If it is
not there, it can receive neither mass nor energy.  Since we create
all this excess energy in the collision, (itself impossible, but to
continue) we need to create an event horizon to another frame of
reference into which to bleed the excess 156% of energy or some
combination of energy and matter.  In essence, you have created a worm
hole, or a black hole, into which one or part of both of you will
disappear, either in body or "enlightenment" or combinations of both
!  In reality, the "event horizon" has to be created by the collision
itself, to create a portal through which you acquire the 156% energy
for the collision (since it had to come from somewhere), and then give
it back, through the same (or another) portal, in the same instant !
This would be "far more exciting" than "any"  tornado you were chasing
initially !  (not to mention down right scary).

If on the other hand you play chicken and "just miss" a collision in
the first place, (boy that was close !) and past each other close
abeam, you would still have an unexpected risk of collision (and you
will loose !) because your masses have increased from rest mass due to
your speed by 1 / (0.8^2) = 1/0.64 = 1.5625 = 56.25%, which, in turn,
creates an unexpectedly great gravitational attraction between the two
of you as you play chicken !  (remember the gravity equations, ie, g
is proportional to 1/d^2 remember !)  SO, in the final instants on
approach, as the "d" is rapidly diminishing towards 0, mutual
attraction is rapidly heading towards infinity, and you both suddenly
realise (if you are lucky, but too late anyway !) that you can not
avoid a collision no matter how hard you both try to swerve to avoid
each other !  The poor old tyres just can't handle it and you skid
together and "wham" anyway ! (RIP guys !).

Should you survive, Einstein would like a word with you."

PS: weather -
Lots of surface water lying around this area would indicate that the

we've only have 43mm this month & 26 last month.  Dandenong Creek is

Don't knock the weather, nine out of ten people couldn't start a

Probably the last complete accurate forecast was when God told Noah there
was a 100% chance of rain.
If you see a heat wave, should you wave back?
Why not move the political conventions to the winter months and then all the

Hi all

This was an exciting day for me as I had never seen snow closeup and the
cold conditions meant that there would be every possibility that I could
break my duck.

After receiving an SMS from Jane about snow at Trentham and there being an
STA out, I decided to drive around and see what I could run into.  I left
my place in Clayton around 10am and headed to Mt Dandenong to see if I
could catch the tail end of a cell which was currently passing over it.
Unfortunately, the cell must've passed further south, as when I arrived in
the Dandenongs, there wasn't any hail/snow lying around (yep, I had very
high expectations!).  Driving around Mt Dandenong in ~<10m visibility
was awkward as I couldn't see what was coming from the southwest.  So, I
left via Maroondah Highway to get below the condensation level, and headed
west until I saw I nice line of cells to the southwest.  

At this point, I was a bit undecided as to what to do.  Should I head back
to Mt Dandenong for the chance of snow/hail, or should I find a lower
lookout so I could see what was going on, and not be engulfed in cloud? 
I decided to head back to Mt Dandenong, but the traffic meant that the
cell caught up, and produced some nice heavy rain.  On that way up I
couldn't resist petrol at 81.5 c/l, so I just had to stop to fill up.

By the time I was high up in the Dandenongs, the cell had passed, but
there was hail lying along the side of the road.  I had to see this, so I
stopped and got out to inspect it, and who should be pulling his car up
beside me?  It was Macca. Chaser convergence for the third time.  

As Macca described previously, we went up to Mt Dandenong and waited for
the next line of cells.  In the process he enlightened me with the
differences between sleet, hail and snow as it was all falling at some
stage during this cell's passage.  We headed north to Kinglake for lunch
and some more cells.  At around 4pm, Macca left for home while I continued
to Mt Donna Buang.

The climb up Mt Donna Buang was the most fantastic experience I can ever
remember.  As I ascended, I began seeing patches of snow along the side of
the road.  I would've stopped there and then to check it out, but there
wasn't a safe place to park the car.  So I continued up and more snow was
visible along the side of the road.  I leant forward to look high up in
the trees, and honestly, I was awestruck by the view.  In the fading
light, all the green ferns and smaller trees had white coatings.  It
looked like those white Christmas's portrayed on tv programs.  The only
difference was that it was _here_, and I was driving through it.  I
continued up, with the amount of snow ever increasing, and reached the ten
mile car park, which was already occupied by a couple of cars. 

When I got out, I didn't know what to do with myself. Walking around, I
estimated about an inch of snow on the ground, with much of it untouched,
ie no footprints or anything.  It was cold with the Kestrel reading ~0.5C,
but I reckon I was shaking more from the excitement of the situation.

My first handful of snow was a real surprise.  I was expecting a wet,
heavy mass which would melt in my hand.  Instead, it was like picking up a
piece of styrofoam.  It was light, had no moisture, and after packing to
make a snowball, would stick to any surface it was thrown at.  I could now
see why it's referred to as 'powder'.  So, I hung around for about a half
hour waiting for it to snow, which it did lightly, before deciding to head
further up the mountain.

I reached another car park which was vacant and played around here for a
bit.  It was now quite dark, and it began to snow with large flakes
visible in the light of my torch.  It was at this moment that some hoons
came to do donuts and wheel spins in this car park.  They were basically
doing this all up and down the mountain.  It was a little distracting from
the original peace and quiet.  However it wasn't all bad as the lights of
their cars did light up the falling snow quite nicely.

After this I decided to head home, although I could've stayed for longer.
Oh well, maybe next time.


By the way, the local radar for Melbourne, some webcam shots and an IR
loop for this can be seen here:

http://www.maths.monash.edu.au/~robert/Weather/Charts/bottomframe.html

And finally, Melbournites, expect the weather to go into a big lull, as
last night I finally took the plunge and purchased a digital camcorder.


Cheers

PS 
If a storm chaser is feeling "under the weather", then I guess this means
they're feeling very good!!

Hey All

I have uploaded some scans of my photos taken of the recent cold outbreak in
Victoria.

The first lot are from Wednesday night. Most of Wednesday was fine and
sunny, and the temp made it up to 18. But by the end of the day the front
started to make it's impact. I was down Cranbourne helping my brother
prepare his house for moving when this grunty looking squall line went
through at dusk, some nice gust and some pretty impressive rain, but very
brief.

These are pics are of the line after it had passed

http://www.photo.net/photodb/folder?folder_id=128012

Then the cold outbreak day came.

I managed to get a day off for Thursday but ended up helping my brother move
house. I had my camera on hand to get the action.

These pics were taken from Cranbourne. Some beautiful sun effects later in
the days and plenty of big anvils.

http://www.photo.net/photodb/folder?folder_id=128010

Oh and before I foget, i got my Sunset Cb pics developed. These shots were
taken last Saturday, a great day.

I have also got a new e-mail address as my ISP went Belly Up.

Hi all,

I'm a newbie to the list, but I've been following it for a while.

Brief description of myself:
Location: Sydney (eastern suburbs)
Occupation: Maths student for another two weeks then met at Weather Co.
Interests: Sailing, thunderstorms (not necessarily in combination!)...

I couldn't resist replying to this one though.

Good call with the collision at 1.6 c because its not possible to exceed
the speed of light (in a vacuum) in any frame of reference. As for the
excess energy being used to create a black hole, this wouldn't happen as
there is no excess energy! In the reference frame of the tornado, the
masses of the cars have increased, but in their own frame, they still see
themselves as having the original mass, and the other car as being much
heavier. In the collision, general relativity takes over as the reference
frames of the two cars are decelerating, so not only can't we use Newtonian
mechanics, we can't even use special relativity, as it only applies to
unaccelerated reference frames. I don't want to go into the calculations
for the collision, as it involves curved space-time...

awesome reply! Though, i'm not sure about the collision at 1.6C due to the
time/spcae change between there reference frames.

well two of them anyway!

Since both Jimmy and I still have to get around to completing reports, I 
thought I would throw a couple of the most impressive pics up temporarily.

The first is of an HP supercell which looked like it was ready to take off - 
I have never seen anything remotely like it. (Photo taken in NW Oklahoma)

The second shows a large pipe tornado prior to it becoming a 1/2 mile wide 
wedge (Photo taken near Panhandle, ENE of Amarillo Texas)

Hi Robert,

That was a nice read. Another person stricken with snow fever! Seriously,
there is something pretty special about watching falling snow. I can't wait
for another fall, if we get one this year.

I've got a question for anyone who wants to answer it. During our trip to
Oberon we pulled up near Mount Trickett on a gravel section only to hear the
gravel explode beneath the car tyres etc. Upon getting outside to have a
look the gravel was elevated about 2 to 4cm above the ground sitting on "Ice
stilts". It was quite amazing. We figured it was to do with the moisture
from rain the day before and then being snap frozen in temps around -3
or -4C that morning. Any thoughts?

Hello all,

The launch of Steve Fossett's solo round the world balloon attempt looks
like being tonight, sometime after 8pm. 

His crew has been in Kalgoorlie for 2 weeks or so awaiting favourable
weather conditions.

Steve will fly the southern hemishpere and complete the journey in about 16
days, all going well.

Our pages at the PAA site which are full of photos, writeups the Kalgoorlie
teachers and students have done:

http://www.schools.ash.org.au/paa/kalgoorlie.htm

http://www.schools.ash.org.au/paa/rtwballoon.htm

We will add photos of the launch if we can get them.

Note the URL for tracking Steve's journey around the globe on a range of
very tasty sat enhanced images.

I don't mind people who don't know anything about weather. I don't know much 
myself. But some people seem to take exception to people asking stupid 
questions. So I suggested that to so that the elitists you mention don't have 
to listen to my stupid questions that I should already know the answer to.

I have usually found the list to be helpful, but sometimes people seem to 
think you have unlimited time to search for information. A short pointer to 
the information to answer the question is probably most useful.

Well, actually, if you really want to know,.......... they put all the
grass on top as a security measure, to neutralize the IR difference
that would otherwise be apparent with the surroundings, so as to
thwart modern day Guy Flakes types, who might seek to use IR guided
weapons on the place.  In addition, the heat generated below helps the
grass grow in Canberra's cold winter, ie, makes it look good and green
all year round, thus minimising the need to use expensive and non
green compliant chemicals etc.  A side benefit is sound proofing. 
Most of the thermals in fact come off the surrounding paved areas, as
small and barely detectable willie willies, but only when someone
spits the dummy inside, which causes a minor gravity wave purtebation,
just sufficient to trigger thermal lift off.  You can tell from which
of the two chambers the dummy spit occurs in by the direction of
rotation of the willie willie.  Clockwise = house of reps,
anticlockwise = senate.

Hi all,

For those of  you into weather records, I've found a good site. Perhaps folk
already know about it. It has weather records/averages/rainfall etc for over
16000 sites worldwide.

The Victorian aviation forecast is as follows:
 S/SW'LY SURFACE FLOW E OF SLOW-MOVING RIDGE FORECAST NEAR 141E AT 11Z,
143E AT 17Z, 145E AT 23Z

We know that the ridge is moving 2 degrees every 6 hours.  How many kms
is 2 degrees at 35S?

Thanks,

Jane

Yes, thanks Caroline, I just tried again myself with no problems..I
accidentally sent a reply to Robert G which was meant to go to the list as a
whole and that was I thought the hiccup was due to an on-site promotion of
some sort..there's always someone wanting to relieve us of our money, (and
also to thank Lindsay for his post)...

By approximation;
at 35S, 1 degree longitude is around 45 nautical miles, which is
approximately 90 km,

Thus the answer to your question is about 180km....although I may need
correcting on this......

pete

ps. I actually wrote that forecast so maybe you will see a speed of movement
of ridge on the next one!!?!

Hi Jane,

For future reference, you might want to use this rule for calculating
the distance per longitude degree (well, it's not a rule, it's something
I made up, I hope it's correct!)

x = [Pi*12740*Cos(latitude)]/360
Where x is what one degree longitude equals along the ground...

So if it is 35S, then:

[3.14 * 12740 * Cos(35)]/360
= 32785/360
~ 91km per degree longitude at that latitude.

12740km is the diameter of the Earth at the equator, effectively all we
are doing is finding the circumference of the Earth at the new latitude
and then dividing it by 360 to get longitude increments.

1 nautical mile = 1 minute of arc
There are 60 minutes in 1 degree.
Therefore there are 120 minutes in 2 degrees & thus 2 degrees is equivalent
to 120 nautical miles.
1 nautical mile is approx 1.85 km so 120 * 1.85 = approx. 222km
Cheers,
Debbie

d=(Cos(lat)*60)nm / degree lon
so d = Cos35 * 60 = 49.1491226622662266.... nm / degree lon
which = 91.078 km / degree lon.
So 2 degrees = 182.156 km
The ridge is moving 182.156 in 6 hrs, so speed of advance is 30.36
kph.

Jane:

One nautical mile is one minute of arc at the earths surface.

As there are 60 minutes in a degree that's sixty nautical miles. times 2
thats 120 nm.

A nm is 1.85 km according to my metric conversion tables so the number of
k's is 1.85 * 120 thats 220km.

Its velocity is 220/6 which is 36.67kmh or 23mph in imperial or 19 knots!

Do the BoM or Australians still use knots / nautical miles / flight levels
in feet / or is it all metric ??

Only at the EQUATOR Debbie.  You forgot to figure the Latitude.  What
you said but multiply by Cos (lat), but that only works if you are
going east west.  If you are going NE to SW say, it will not work, but
over short distances, a rough approximation is to use middle lat.  To
do it properly you should do the full spherical geometry formula.  Fo
further info see http://www.best.com/~williams/gccalc.htm.

2 degrees of latitude is 60 nautical miles. 2 degrees of longitude is 60
nautical miles only at the equator.

I'm not quite sure what their source data is. Using the ACT as an
example, their station coordinates (and data) seem to match real
stations, but these stations don't match the places for which they 
are listed - for example:

Canberra - matches Canberra Airport
Hall - matches Mount Stromlo
Royalla - matches Acton (the pre-1939 Canberra site)
Gibraltar - matches CSIRO Forestry (Yarralumla)
Gudgenby - matches Gudgenby
Tharwa - matches Honeysuckle Creek
Williamsdale - matches Orroral Valley

In each case the data, and the period of record, also match up
pretty well.

I can sort of understand how an algorithm that looks for the nearest
inhabited place might come up with Tharwa as a match for Honeysuckle
or Williamsdale for Orroral, but some of the other matches are a 
mystery to say the least.

I haven't analysed any other states in detail yet.

The only record at a site with a reasonable length of observations that
I found on a quick glance was 0.0 at Cape Byron, and I am rather
sceptical of this - it seems unlikely that a site could break its
all-time record by 3.3 degrees without records falling around it.

There were a fair number of near-misses, most notably at Lismore where
the min of -0.6 missed the record by 0.4 degrees, but most places seemed
to be at least a degree or two away. (Kingaroy, which missed by 0.3,
has had a very recent site change whose impact cannot yet be assessed).

My scepticism here is further reinforced by the fact that Cape 
Byron has reported 0.0 again today, despite 7/8 cloud, a 22 km/h
wind and nothing else below 6 in the whole Northern Rivers district.

Dear All

I am an Ecological Sustainable Design engineer, basically I try and help
architects to design their buildings to consume less energy. As part of our
work we simulate the energy consumption of buildings using real hourly
weather data. The availability of this data is some what limited and I
would to draw upon this groups expertise and ask if anyone has come across
any sites that have hourly weather data available.

Any help is greatly appreciated, does anyone have a contact at BOM that I
could talk to?

Thanks, Simon.

NOTICE OF JUNE SCIENTIFIC MEETING

The next meeting of the AMOS Sydney Centre will be held on Wednesday June 
27, 2001
Venue: University of New South Wales
             School of Physics
             Room 27, Old Main Building
             Parking is available on campus (for a fee),
but free parking on Barker St. is probably the best option.
The Old Main Building is opposite the Barker St. gate.
Time:   7:30 p.m. for a 7:45 p.m. start.

The program includes announcements, the current weather situation and 
forecasts for the week. The main seminar will be on "Winds and Runway Usage 
at Sydney Airport", by Professor Jason Middleton (full details on final page).

Members are invited to join the speaker and committee any time after 6pm 
for dinner at the highly recommended Mamma Teresa Italian Restaurant, 412 
Anzac Pde. Kensington (one block south of UNSW   easy walking distance!). 
It would assist our planning if members planning to attend the dinner 
phoned the Secretary (93854545).

Please take note of the two items on the next page.
Important Information for AMOS Sydney Members

1.      Over the past couple of years, the AMOS Sydney Centre has tried to 
conduct a number of its meetings at UNSW. There are a number of reasons for 
this, which include a desire to hold our meetings in more than one 
location; an attempt to attract members, and potential (student) members 
from the south side; and the fact that the Bureau is not a very suitable 
location due to security difficulties. So far, however, our forays south 
have been less than an overwhelming success. This month's meeting is thus a 
make-or-break effort. For those of you living on the north side, we would 
like to point out some recent changes: the Eastern Distributor has made the 
journey very much quicker and more convenient - yes, you do have to pay a 
toll, but the Harbour Tunnel connects to it quite well (take the Anzac Pde. 
exit); you no longer need a visa. (If you can't make it this month, but 
would still like to support our UNSW meetings, please let someone on the 
Committee know.)
2.      The Centre will be conducting a Weather Radar Course. The course 
will be held on Saturday afternoon, August 25, at Macquarie University. 
Notes will be provided on severe weather, radar, etc. The cost will be $20 
for the general public, $10 for students and AMOS members, and AMOS student 
members free. This should be an excellent opportunity to learn how to make 
maximum use of the Bureau of Meteorology's radar images, which are now 
available to all free of charge on their website. More information will be 
available early next month, but please pencil it in your diary.
AMOS Talk, Wednesday June 27.

Room 27, School of Physics
(Old Main Building)
University of New South Wales
7:30 p.m. for a 7:45 p.m. start


Winds and Runway Usage at Sydney Airport

Professor Jason Middleton
Aviation/Mathematics, UNSW

Wind velocity data acquired over a period of several years from anemometers 
at Sydney Airport were analysed to determine means and gust statistics. 
These statistics were used to estimate runway availability for aircraft 
use, which were then compared to actual usage. Utilising 2 second raw data 
and 10 minute means to determine gust factors (peak/mean) results in a gust 
factor of approximately 1.3. Utilisation of wind and gust factor data in 
association with operational limitations shows that the north/south runways 
are available over 75% of the time, but used significantly less due to 
noise abatement procedures. The data set also contains some interesting 
phenomena, with implications for flight safety.
This work was jointly undertaken with Rod Potts (Bureau of Meteorology) and 
Peter Monypenny and Richard Manasseh (UNSW).

Jason has been with the University of New South Wales for 20 years, where 
he was largely responsible for establishing the Physical Oceanography group 
within the School of Mathematics. Some eight years ago he established the 
Aviation Program at UNSW, which teaches both Flying and Operations 
Management students

Hey Lindsay,

I can't say i've ever experinced this, even after very cold snaps, though
your logic sounds plausibale. Maybe the road was re-graveled after the snap
freeze?

The suggestion of segregating the list repulses me. It's that simple. This
is not university, this is not school, it's an email list that was founded
with the intention of a share-all attitude (I think?). For the people who
you don't want to bother, they can filter the list as need be. If you are
concnered that your going to bother some people, say it in the subject like
'Newbie Question' - though I presonally would not do this, rather state your
question in the subject and a reader can decide for themselves whether to
read it or not.

I too have found it very usefull because most people are good about
answering questions and what not. I think maybe my problem was my questions
were more science based rather than weather based, the one I'm thinking of
from a long long time ago was 'Why does rain prefer a humid environment to
fall in but hail prefers a dry?' - When i first got into wx this duality
made no sense and i got some very abrupt replies when i didn't understand
the jargon in the original answer to the question.

Anyway, all in the past - cheers, lyle

Hi Jimmy,

I totally know where you are comming from and in a professional capacity, I
think the same way. But my refernce was more to basic ideas, that are well
accepted, which is more what comes our way on this list, even some threads
that seem 'cutting edge' rarely are. So why hold back? Obviously it would be
stupid of me to talk about my current research because it's IP to CSU but if
you were to ask me some question regarding convection in the tropics (my
research) that didn't relate on the very focus, I would have no quams
talking about where the science is currently at regarding this. Obviously it
would just be my very unauthoritive opinion, another reason not to worry
about having an open discussion.

Cheers, Lyle

Hi all,

Just checked around this ornings Observations around Adelaide and came up
with this one.

Nuriootpa 19 05:30 -1.1c -Dp 123%Rh CALM     - - 1023.6 0.0

Do you think that 123%Rh is some kind of new record :)

I guess it's along the same lines as Parafield getting 900mm in 10 minutes
sometimes.

regards

Andrew

Hi all

I'm wondering if someone [Lindsay?] might like to add a scan from a
reasonable scale topographic map to their web site so that those readers on
the list not familiar with the Blue Mountains can really see where you are
all talking about when you talk about places like Shooters Hill.  Nothing
like actually being able to follow a snow chase on a map!

Cheers!

Phil

Hi Lyle,

I hope to be studing some courses that will lead me in to a  meteorology
degree but ill be doing that over here. As for going over to the US in 2
years i want to be chashing. I really wanted to go next year but am a
"newbie" to this weather stuff and next year ill be tied down with study and
also i want to get to know the chasers on this list and hopefully chase with
them sometime this year.

Subject: aus-wx: Greating Chase Maps - a thought for all chasers - spatially documenting 
 your chases.
Sender: aussie-weather-approval at world.std.com
Reply-To: aussie-weather at world.std.com

Disclaimer:
This is just an idea, a discussion starter if you will, for the
Australian / ASWA chaser community.  I think this might be something
worth thinking about.

Subject:
Standardizing ASWA Chase Report presentations on the web.

Sub Topic:
Spatially documenting chases - Generating Chase Maps - a thought for
all chasers perhaps.

Example:
Maps from http://birds.rhyme.com.au/  (as an example of one source
only)  (There must be others available with Topo data as well - anyone
?)

Genesis:
Originally stemming from a question by Phil Bagust on 19 June 2001
about the Shooters Hill NSW snow chase of Lindsay Pearce and Adam
Southers on 15 June 2001.

Case Study:
Generating the maps for the Shooters Hill Snow chase Area.

Executive Summary:
The thought has often occurred to me (when viewing many chaser sites)
that they vary somewhat in layout, navigability, presentation and
general "feel".  Everyone has their own ideas and style of course, but
I think a chase is a "chronological adventure" and might best be
presented as such, so that the site viewer can "come along for the
ride" from the beginning as it were.

Desired Outcome:
Documenting the chase in a format as though it were an expedition. 
Most chases done locally are easy to document, but long range and long
time period chases (like thunder down under) obviously involve quite a
bit of pre-planning, and cover a hell of a lot of ground in the field.

Benefit:
With a little thought, ASWA chasers could set a new standard in chase
reports for the world wide web here.

Methodology:
High tech equipped chasers should have a GPS (only $300 these days),
so, if they are good scientific chasers with any methodology to them,
they should have a clipboard on the seat, and record (at every stop)
all the relevant spatial data, ie:-
Location:	Date time, lat, long, altitude GPS), view azimuth etc.
Event details:	Narrative as appropriate, along with all the relevant
weather data / info of course !
Pic Details:	Film Num, exposure number, zoom, f stop, shutter speed,
EV if known, exposure compensation if used, etc, etc.......

The benefit of this mapping exercise is I think that:
(a) The web viewer gets the "whole story".
(b) It is simple, free, readily available and easy to do.

Example:
Shooters Hill Chase Maps - a Case Study in the Methodology:

Go to the Auslig site at http://www.auslig.gov.au/ and do a search on
Shooters Hill gives you:
http://www.auslig.gov.au/cgi-bin/gazm00?placename=shooters+hill&placetype=0&state=0

The two at the top are the ones you want, in NSW.
Note the Latitude and longitude, you will need that data below.
Then click on the blue shooters hill name and you get
http://www.auslig.gov.au/cgi-bin/gazd00?213669

Then click on the BLUE CROSS

Which gives you:
http://www.auslig.gov.au/cgi-bin/col250?si5508C213669

Having got that far doesn't give you much, but you know where it is,
and you have the lat long.

Next, go to  http://birds.rhyme.com.au/maps.html   It looks like a NT
bird site, but stay with me.

Click the "Large Alice Springs Area" link.  That will produce 
http://birds.rhyme.com.au/virtmap/oz/50/600_400/133_51_19/23_40_49/birds.html

Now note the format of the URL.  This is the key to it all.  The
numbers towards the end  (133_51_19/23_40_49) are the longitude and
latitude of the centre of the map.  The numbers at the front (600_400)
are the screen size of the image in pixels, ie VGA 800 x 600, and the
(50) is the zoom factor.

Now Your Lat and Long for Shooters Hill NSW were: (from Auslig)
Lat	33º 53' S	[Decimal Degrees -33.89840º]
Long	149º 52' E	[Decimal Degrees 149.86790º]

Now, put them in the URL above, dso that it now becomes:
http://birds.rhyme.com.au/virtmap/oz/50/600_400/149_52_00/33_53_00/birds.html

Next, say you want a large picture, say 1280 x 1000, then change the
image size figures in the URL.  It now looks like
http://birds.rhyme.com.au/virtmap/oz/50/1280_1000/149_52_00/33_53_00/birds.html

Now, open that in your browser.

This gives you a map centred on Shooters Hill in NSW that covers all
of SE Aus, ie, NSW and Vic.  Note below the picture in very small
print is the scale.  The scale is:  1 pixel = 50.3192 seconds of arc,
(which is the same as 1.554 Kilometre / pixel).

Now to zoom in to a greater detail, just use the zoom buttons at the
bottom, or, better still, do it direct.
Notice in the URL again the figure at the beginning, just before the
monitor dimensions.  This is the zoom number.  Change the 50 to 10,
and you have
http://birds.rhyme.com.au/virtmap/oz/10/1280_1000/149_52_00/33_53_00/birds.html

Open that up and you get a pretty good map of the main roads of the
area.  If you really want to drill down and go large scale
(remembering that the map is centred on Shooters Hill, ie, the lat and
long figures in the URL) so that position is at pixel point 640/500
(since it is a 1280/1000 image).

change the zoom to 5, you get
http://birds.rhyme.com.au/virtmap/oz/5/1280_1000/149_52_00/33_53_00/birds.html

and if you really want to zoom in, change it to 2 and you get
http://birds.rhyme.com.au/virtmap/oz/2/1280_1000/149_52_00/33_53_00/birds.html
At this level, The scale is: 1 pixel = 4.4647 seconds of arc, which is
1 pixel = 138 metres !

In any case, you can save the gif file and the distance scale
information, and then use it as a base map, ie, edit it with a
graphics package to add names of towns, main roads, draw in your chase
route, place date and time blobs where events occurred and or you took
photo / video footage or made an observation etc, then make it into a
clickable map that opens individual frames on the spots for the
reports, photos, video or whatever.

Now, admittedly there is no Topo or Name info on this map, but the
rivers etc give a pretty good idea if you know the area at all, and
for a more general view we could go on to other map generating sites. 
Quite obviously though, this little exercise shows the possibilities.

Any thoughts out there ?

Regards,
PC

Hi Peter and all,

A few comments and points to note:

- People who chase, aren't actually chasing for ASWA, no one chases for
ASWA in itself, ASWA is just an association, it just so happens that a
lot of ASWA members are also storm chasers, but many were storm chasers
before ASWA was born :)

- ASWA doesn't encourage storm chasing (we don't discourage it either,
the only thing that ASWA has recommended is that those members who do
chase, report anything they see to the BoM, but this goes for all
members who experience a severe thunderstorm).  We also strongly
encourage ASWA members to join the BoM spotter network (ask your state
rep for details for those interested).

- Taking the previous point, for this reason - people who write chase
reports, aren't doing it for ASWA - they are reporting a personal
account of what they experienced, hence ASWA cannot ask anyone to
standardise their report format.  The only reports that ASWA "write" is
I know some people report events to the BoM, and send them under an ASWA
report - this is different, but these are not storm chase reports, these
are generally damage reports.

- The other activity ASWA encourages (some states anyway), and this is
not to be confused with storm chasing, is reporting and examining severe
weather damage by severe weather phenomena.

Hence Peter, ASWA is in no position to ask people to standardise their
reports, this could only ever be a personal suggestion by yourself.

One last point to note is that the aussie-weather list is not an ASWA
list, it's a list to the general public.  Best place to put proposals is
your state rep, who will discuss them with you and/or forward them to
the committee.

Hope this clears everything up :)

There's a problem (that we know about) with AWS wet-bulb sensors 
when the wet bulb temperature is below 0. We're working around this 
problem by planning to install humidity sensors instead at sites which
experience wet-bulbs below 0, but this process is incomplete. 
Nuriootpa is one site that still has a wet-bulb probe. 

On another data quality issue, Cape Byron's min thermometer has
(to no-one's surprise) been reported faulty. The minima of 0 on 
Saturday and Monday should be disregarded.

Hi Peter
<p>I don't think we need to go to such lengths to put so much detail in
reports. What it comes down to, is that it is a hobby. A very time consuming
one, and all chasers who write lengthy reports, scan there photos, try
and download any model data for the day that hasnt been deleted off websites,
find the odd sat pic to throw in the report,&nbsp; put them all online...know
it takes a long time.&nbsp; In the middle of a chase, the last thing you
want to do is write down down details of lat/long/shutter speeds/camera
settings etc for every photo, you would much rather be watching and filming
the mesocyclone a couple of km away....&nbsp; Also when it comes to the
crunch, there are only a few people make the effort to travel outside there
citys to chase storms in Australia,(some people dont like a 2-3-4 hour
drive to a target area, and some people have other commitments etc). and....
even fewer of those people have web pages and write reports on events they
witness. Only die hard weather enthusiasts are really interested in the
reports anyway.. we dont get too much feedback on them,&nbsp; they are
more for our own personal records than anything else i think.
<p>I think maps are a good idea though.&nbsp; =)

<p>Subject:
<br>Standardizing ASWA Chase Report presentations on the web.
<p>Sub Topic:
<br>Spatially documenting chases - Generating Chase Maps - a thought for
<br>all chasers perhaps.
<p>Example:
<br>Maps from <a href="http://birds.rhyme.com.au/">http://birds.rhyme.com.au/</a>&nbsp;
(as an example of one source
<br>only)&nbsp; (There must be others available with Topo data as well
- anyone
<br>?)
<p>Genesis:
<br>Originally stemming from a question by Phil Bagust on 19 June 2001
<br>about the Shooters Hill NSW snow chase of Lindsay Pearce and Adam
<br>Southers on 15 June 2001.
<p>Case Study:
<br>Generating the maps for the Shooters Hill Snow chase Area.
<p>Executive Summary:
<br>The thought has often occurred to me (when viewing many chaser sites)
<br>that they vary somewhat in layout, navigability, presentation and
<br>general "feel".&nbsp; Everyone has their own ideas and style of course,
but
<br>I think a chase is a "chronological adventure" and might best be
<br>presented as such, so that the site viewer can "come along for the
<br>ride" from the beginning as it were.
<p>Desired Outcome:
<br>Documenting the chase in a format as though it were an expedition.
<br>Most chases done locally are easy to document, but long range and long
<br>time period chases (like thunder down under) obviously involve quite
a
<br>bit of pre-planning, and cover a hell of a lot of ground in the field.
<p>Benefit:
<br>With a little thought, ASWA chasers could set a new standard in chase
<br>reports for the world wide web here.
<p>Methodology:
<br>High tech equipped chasers should have a GPS (only $300 these days),
<br>so, if they are good scientific chasers with any methodology to them,
<br>they should have a clipboard on the seat, and record (at every stop)
<br>all the relevant spatial data, ie:-
<br>Location:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Date time, lat, long,
altitude GPS), view azimuth etc.
<br>Event details:&nbsp; Narrative as appropriate, along with all the relevant
<br>weather data / info of course !
<br>Pic Details:&nbsp;&nbsp;&nbsp; Film Num, exposure number, zoom, f stop,
shutter speed,
<br>EV if known, exposure compensation if used, etc, etc.......
<p>The benefit of this mapping exercise is I think that:
<br>(a) The web viewer gets the "whole story".
<br>(b) It is simple, free, readily available and easy to do.
<p>Example:
<br>Shooters Hill Chase Maps - a Case Study in the Methodology:
<p>Go to the Auslig site at <a href="http://www.auslig.gov.au/">http://www.auslig.gov.au/</a>
and do a search on
<br>Shooters Hill gives you:
<br><a href="http://www.auslig.gov.au/cgi-bin/gazm00?placename=shooters+hill&placetype=0&state=0">http://www.auslig.gov.au/cgi-bin/gazm00?placename=shooters+hill&amp;placetype=0&amp;state=0</a>
<p>The two at the top are the ones you want, in NSW.
<br>Note the Latitude and longitude, you will need that data below.
<br>Then click on the blue shooters hill name and you get
<br><a href="http://www.auslig.gov.au/cgi-bin/gazd00?213669">http://www.auslig.gov.au/cgi-bin/gazd00?213669</a>
<p>Then click on the BLUE CROSS
<p>Which gives you:
<br><a href="http://www.auslig.gov.au/cgi-bin/col250?si5508C213669">http://www.auslig.gov.au/cgi-bin/col250?si5508C213669</a>
<p>Having got that far doesn't give you much, but you know where it is,
<br>and you have the lat long.
<p>Next, go to&nbsp; <a href="http://birds.rhyme.com.au/maps.html">http://birds.rhyme.com.au/maps.html</a>&nbsp;&nbsp;
It looks like a NT
<br>bird site, but stay with me.
<p>Click the "Large Alice Springs Area" link.&nbsp; That will produce
<br><a href="http://birds.rhyme.com.au/virtmap/oz/50/600_400/133_51_19/23_40_49/birds.html">http://birds.rhyme.com.au/virtmap/oz/50/600_400/133_51_19/23_40_49/birds.html</a>
<p>Now note the format of the URL.&nbsp; This is the key to it all.&nbsp;
The
<br>numbers towards the end&nbsp; (133_51_19/23_40_49) are the longitude
and
<br>latitude of the centre of the map.&nbsp; The numbers at the front (600_400)
<br>are the screen size of the image in pixels, ie VGA 800 x 600, and the
<br>(50) is the zoom factor.
<p>Now Your Lat and Long for Shooters Hill NSW were: (from Auslig)
<br>Lat&nbsp;&nbsp;&nbsp;&nbsp; 33&ordm; 53' S&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
[Decimal Degrees -33.89840&ordm;]
<br>Long&nbsp;&nbsp;&nbsp; 149&ordm; 52' E&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
[Decimal Degrees 149.86790&ordm;]
<p>Now, put them in the URL above, dso that it now becomes:
<br><a href="http://birds.rhyme.com.au/virtmap/oz/50/600_400/149_52_00/33_53_00/birds.html">http://birds.rhyme.com.au/virtmap/oz/50/600_400/149_52_00/33_53_00/birds.html</a>
<p>Next, say you want a large picture, say 1280 x 1000, then change the
<br>image size figures in the URL.&nbsp; It now looks like
<br><a href="http://birds.rhyme.com.au/virtmap/oz/50/1280_1000/149_52_00/33_53_00/birds.html">http://birds.rhyme.com.au/virtmap/oz/50/1280_1000/149_52_00/33_53_00/birds.html</a>
<p>Now, open that in your browser.
<p>This gives you a map centred on Shooters Hill in NSW that covers all
<br>of SE Aus, ie, NSW and Vic.&nbsp; Note below the picture in very small
<br>print is the scale.&nbsp; The scale is:&nbsp; 1 pixel = 50.3192 seconds
of arc,
<br>(which is the same as 1.554 Kilometre / pixel).
<p>Now to zoom in to a greater detail, just use the zoom buttons at the
<br>bottom, or, better still, do it direct.
<br>Notice in the URL again the figure at the beginning, just before the
<br>monitor dimensions.&nbsp; This is the zoom number.&nbsp; Change the
50 to 10,
<br>and you have
<br><a href="http://birds.rhyme.com.au/virtmap/oz/10/1280_1000/149_52_00/33_53_00/birds.html">http://birds.rhyme.com.au/virtmap/oz/10/1280_1000/149_52_00/33_53_00/birds.html</a>
<p>Open that up and you get a pretty good map of the main roads of the
<br>area.&nbsp; If you really want to drill down and go large scale
<br>(remembering that the map is centred on Shooters Hill, ie, the lat
and
<br>long figures in the URL) so that position is at pixel point 640/500
<br>(since it is a 1280/1000 image).
<p>change the zoom to 5, you get
<br><a href="http://birds.rhyme.com.au/virtmap/oz/5/1280_1000/149_52_00/33_53_00/birds.html">http://birds.rhyme.com.au/virtmap/oz/5/1280_1000/149_52_00/33_53_00/birds.html</a>
<p>and if you really want to zoom in, change it to 2 and you get
<br><a href="http://birds.rhyme.com.au/virtmap/oz/2/1280_1000/149_52_00/33_53_00/birds.html">http://birds.rhyme.com.au/virtmap/oz/2/1280_1000/149_52_00/33_53_00/birds.html</a>
<br>At this level, The scale is: 1 pixel = 4.4647 seconds of arc, which
is
<br>1 pixel = 138 metres !
<p>In any case, you can save the gif file and the distance scale
<br>information, and then use it as a base map, ie, edit it with a
<br>graphics package to add names of towns, main roads, draw in your chase
<br>route, place date and time blobs where events occurred and or you took
<br>photo / video footage or made an observation etc, then make it into
a
<br>clickable map that opens individual frames on the spots for the
<br>reports, photos, video or whatever.
<p>Now, admittedly there is no Topo or Name info on this map, but the
<br>rivers etc give a pretty good idea if you know the area at all, and
<br>for a more general view we could go on to other map generating sites.
<br>Quite obviously though, this little exercise shows the possibilities.
<p>Any thoughts out there ?

Hi Simon,

Since no-one else appears to have responded to your email, I'll give it a 
go. The BOM does have pseudo hourly observations in the form of automatic 
weather station METARAWS reports. These can be hourly or half hourly, but 
not exactly so. If certain weather criteria are exceeded the station 
produces a SPECI report immediately. If the report is within 10 minutes of 
a routine report, that routine report is not sent. The SPECI report is 
subtly different to a routine report, particularly for the of wind. The 
normal 10 minute averaging is suspended. This is to enable significant wind 
changes to be reported without the smoothing and time lag inherent in 10 
minute averages. You do have to be careful about using the wind speed on a 
SPECI as the real MAX wind since it won't be the standard 10 minute 
average. I think the Wind Gust report is treated identically though.

For the most part these observations are available in real-time on the 
BOM's www site, though some states show more sites than others. The data is 
only updated on an hourly basis though. The data is currently archived only 
within the Regional Office in each state rather than centrally in 
Melbourne. You would have to contact the Climate Section in the state you 
are interested to get a data series from one or more stations. We have been 
archiving for at least 5 years at most pre-existing sites.

Some sites (close to the Capital Cities) also have one minute reports, 
which again, most regional offices archive.

I believe the BOM is moving towards a new 10 minute standard which will be 
centrally archived at the National Climate Center in Melbourne. I'm not 
sure how this is progressing, but there will have to be significant 
comms/software changes at the AWS sites for this to happen. I don't think 
this will be freely available in real-time as one hour is the current 
minimal update time for free data on the BOM www site.

The data from METARAWS reports is temp, dewpoint (humidity) at screen 
height (1.5m ?) , wind direction and speed (10 minute average at 10 metres 
height), Wind Gust (highest 1 second wind in the last 10 minutes), pressure 
(ICAO standard QNH), rainfall since 9AM and rainfall in the last 10 
minutes. A very few sites have horizontal visibility, cloud octas and 
height. No sunshine data would be available though.

Hope this helps for a start.

Cheers
Hank

Hi Phil,

Sorry for the delay in getting back to you. My isp has had problems all day.
I'd love to set something up on my page on the Oberon/Blue Mountains area.
The main problems is time, as we are in the process of setting up a new
business. The other problem is that I am a beginner when it comes to home
pages etc. We don't own a scanner but I did know of a great detailed mapping
site but I have lost the link! If folk know of any great sites, let me know
and I will look at it all when I get time, and who knows when that will be
:)

Hi Phil and all,

I've just found a decent map of the area, its not topographical but its
clear and quite detailed of the Blue Mountains area. I will try to add some
notes to it or something at some stage but at least it gives you an idea of
the area. Go to the south of Oberon to see the Shooters Hill area. The
"Hill" there at around 1350 metres is just west of the town. Mount Trickett
at 1362 metres is near Jenolan Caves, just to the west of the caves
actually. Mount Bindo is just to the south of Hampton (east of Oberon) at
the first road junction you see on the map there. If any of this is
incorrect folk, feel free to correct it. I'm in a rush.

Map is here for now:   http://www.lisp.com.au/~violin/Graphics/katoomba.gif

Robert,

The sunset pictures came out great, what model camera did you get?

I have the Sony TRV-230e, but haven't got a firewire card yet, so I can't do
any captures from it.

Being nowhere near the expert that I'm not, I wouldn't be at all surprised
if there was some rotation on the surface of the Bristol Channel from the
funnel in the first photo.  Just looks too strong and organised not to cause
some disturbance at ground level.

But I am more than willing to be proven wrong.

Hi Tropos.
Its still interesting to see some tropical showers still ligering not far
north of Darwin, but whats interesting is the tongue of mid level (alto
stratus/altocu mix) moisture spreading south-eastward across the top end and
coming ashore just south west of the Darwin region.Also a nice long wave
trough building well west of WA with a low below 966hpa south west of
Perth.For rest of Australia its good Mars viewing weather, I had a look last
night with my Kids, and even through a low powered telescope surface marking
can be seen. The planet will approach to within 49 million klm I think on
the 22nd of June, who will be first to spot any clouds on Mars...regards
Clyve Herbert..

I hope that wasn't one of the nice new M Trains that we are doing at work
Clyve.

I would hate to have to explain to the guy that has to fix up the decals on
it that I know the person that was driving the train when it happened.  :-)

<DIV><FONT face=Arial size=2>The present high pressure phase affecting Australia 
looks to be rather strong and should persist for most of the week. The long wave 
trough over the Indian Ocean is slow moving but rather strong, although lacks 
the moisture inflow from the tropics indicating the jet is further south, unlike 
last weeks effort which saw the sub tropical jet dragging heaps of moisture from 
north of Australia. It looks as if early next week this long wave trough will 
encroach onto the Australian Mainland and if the following high ridges to south 
of 50 degrees it may indeed inject a reasonable cold air field&nbsp; across the

Hey Peter,

i think this is great idea. I've got a funny feeling that die hard storm
chasers (or storm spotters) in Australia and our friends in the USA would
love to have this info added to chase reports. It would definitely make
storm chase reports more personal to the reader.

Only points which i would say would make it a draw back are: -
  *  Time to do reports would increase
  *  May encourage other people who are not weather orientated to try and
chase, possibly with disasterous results (like in USA)
  *  Size of reports

Positives :-
  *  more detailed storm data on all aspects

GPS is a great idea. But i also think expansive as chasing for most is only
a hobby. But dare i say, that some people have already spent thousands of
dollars on Chase equipment ;-)

I think this will be on a person by person (or Webhost) baisis on whether it
would be standardised. I for one am trying to do maps and storm tracks,  but
at the moment, am not having much time. It is a lot of work. Hopefully for
this coming storm season I can get these maps done for Storm reports for the
bsch pages.

Anyway, i'll leave this up for discussion. A great point to consider Peter.

Hey Simon,

The tempreture difference between Canberra and the high alpine is due to an
inversion but it's not formed by the high, though it probbaly wouldn;t exist
if it wern't there. See the High gives calm conditions and *everything*
radiativly cools, all the time. So as the surface cools, it cools the air
around it - actually the air cools too but is also warmed/cooled by
sorounding air, it all comes down to it's 'efficiency' in cooling and how
the radiaiton is transmitted to space and to the ground. Anyway, this is a
complex side of the problem but, for simplicity, lets just say the ground
cools.

So, if we have a u-shaped valley, the air along the walls of the valley
cools and gets denser and, thus, slides down the valley wall into the
valley - this is known as Katabatic flow. But there must be mass
conservation, so that air in the center of the valley rises. This is called
a solenoidal circulation because it resembles the lines of a magnetic field
through a solenoid. See the attached file (Microsoft Word) for a quick
schematic of the circulation.

So as the air overturns in the valley, a cold pool forms, with less dense
air (warmer) rising and the denser air (colder) sinking, continually through
the night. Also note that, due to the circulation, all moisture transported
into the air from the surface will also be carried to the bottom of the
valley, hence the dew point will be higher. This process will also fuel
valley fogs.

At day break, the surface heats up, generally stronger on one side of the
valley which has  a better sun-orientation angle. The circulation is now
reversed with warmer air on the walls becomming less dense and rising
(Anabatic flow). If you spend much time in the mountains, you'll see this
clear as day - literally ;) If the day is clear and the sun strong, a usual
occurance during a High, the valley fog formed at night will 'climb' the
walls.

Cheers, Lyle

Hi all.

 Ive just seen sno-info and weatherzone weather station reports and to my
surprise canberra is sitting on -3 but Mt Hotham and Crackenback stations
are above zero. From what ive read on weather forum this is due to inversion
from the High that we are under thw influence of at the moment.

Any way to my question.
Although canberra is -3, crackenback is 1.2, ant Mt hotham is 0.9.Canberra's
Dp is -3.6 crackenback is -19.2
and Mt hotham is -19.5. I would like to know what is Dew point? how is it
measured? and how it affects me (does it feel colder i.e at crackenback does
it feel well below zero even though it 1.2deg)?

Thanx in advance

Simon Angell

WZ temp -3.0 My temp -2.6 and 6.5 in my bedroom.. time to turn the heater on
methinks...

A reasonably cool morning in southern NSW.

Just noticed the 7.00 am temp at Braidwood was sitting on almost -9
well -8.8 anyway (which probably means the min would have been a little
less).

In Canberra, Tuggeranong got to -7 and the airport got to -5. By 8am it has
now warmed up to -1 with thick fog - should be an "interesting" drive to
work.

Hi all,

Thanks for all the replies and the URLs.  Didn't expect it to start off
such a chain of posts!  Basically my argument was that a picture is worth a
thousand words.  On the down side is time and resources - scanners and more
farting around with HTML with what is, after all, a hobby for most of us.
The whole GPS idea is great, but then again, I'm still saving up for a
camcorder, so its a matter of priorities......

We had a couple of interesting discussions on this on Weatherzone as well. I
suggest you read them as they may modify your thinking. Not radically
granted, but a little. Basically your explanation is correct but the
mechanism for the formation of fog does not read correctly.Yes, this
situation up a good for the formation of valley fogs but the circulation
does not carry the moist air to the surface. It is in fact trapped there.

Fairly cold at Wollongong as well. Although it is around 4 degrees warmer than yesterday, there is a fairly fresh SW wind blowing which has a good windchill to it. It feels much colder this morning than yesterday. I had 7.7 degrees at 5:30am yesterday and 11.7 today.

Beautiful clear skies, and some some cumulous towers and small anvils off the coast at sunrise this morning.

A small cold pool south of Adelaide on the north side of a fast moving low
looks to be heading for the southern part of Tasmania,this low is
interesting and may indicate a brief strengthening of the ridge over the
western Aus Bight region,also a weak baroclinic cloud area over the top end
has also moved rapidly south-eastward towards northwest QLD indicating a
strengthening mid and upper flow in theta region may indicate an upper
system over central QLD.regards Clyve H,.

Hi Phil and all,

Couldn't resist mucking around some more on the map link I set up for the
Oberon/Blue Mountains area. I've added some daggy little mountain icons
(drawn ones) to indicate the Mountains; Bindo, Trickett and also Shooters
Hill, and their heights above sea level.

Remember, you can also access this graphic under "2001 Chase/Snow Reports"
in the left margin of the main page. Just click on the link there and you
will find it all. Back to work for me :)

Further to my earlier post, from the 9.00am obs it looks like Cooma (town 
not the airport site) managed to get to -11 last night. I notice  the record 
for June is -11.5 so the record was probably just out of reach.

With the significant warming of the middle atmosphere due later this week 
and into the weekend, my experience is that the greater temperature 
difference that will be created below and above the inversion level will 
tend to maintain fogs in Canberra to much later in the day (thereby reducing 
any mixing down of warmer and drier air into the fog bank and assisting its 
break up).

This could result in some quite low day time maxima in the days ahead.

Now up to +1 in Canberra at 11.00am - warming nicely   ;)

Interesting situation - looks like the cold was largely confined to
the far SE of NSW.

Cooma came in with -10.5. This is not a record; their June (and
all-month) record is -11.5 on 16 June 1992. (This was a very
frustrating night in Canberra, where I was living at the time; I went
to bed at about 10 with it standing at -5, convinced that the all-
month record of -10.0 (or at least the June record of -8.5) would be
put under serious pressure, but the wind got up and that was as cold
as it got). An experimental site ANU was running at the time on Long
Plain, north of Kiandra, recorded a terrestrial min of -27 during 
this period (no screen temps unfortunately; with that number I would
have expected a screen min in the -20 to -23 range). The current 
situation actually seems quite similar to the 1992 one.

Braidwood's (rounded) min was -9. Their record is -9.2 (15 June 2000),
but it is a short record. We should get a more exact figure later
in the day. Another interesting obs was -4 at Bega. This is not a
record either (Bega's record is -8.1, the lowest ever recorded in
Australia so close to the coast), but it's the lowest for a while.

Corryong only had a max of 3.9 yesterday in persistent fog, missing
its June record (22/6/1984) by 0.1. Their all-time record is 3.1, set
on 9 July 1995. Again, that was a situation which has parallels with
the present one (a strong inversion developed around 1200m after two
days of high pressure and persistent fog in northern Victoria/
southern NSW). In 1995 this cold layer of air was deep enough to remain
intact as it was swept over southern Victoria by strong northerlies 
ahead of an approaching front, giving Melbourne a max of 6.8 on the
10th (and Ballarat only 2) with near gale-force winds - definitely
not the most pleasant day I've ever experienced in Melbourne!
(although it was worth it to see a forecast which read 'bitterly
cold northerly winds turning milder south-westerly later'). The
present situation isn't as extreme as that, but we've still had
below-average maxima with fresh northerlies yesterday, and will 
probably do so again today.

Hi Chris

Yep, mine's the same: Sony TRV-230e
I'm fortunate as I can simply plug my camera into the computers here and
upload anything with just a normal tv-video cable.  Although, I'm
currently working on getting the movies down to a user-friendly size :)

Great stuff Clyve.  Actually, a small morning glory did eventually
develop, but was not nearly as prominent as the curved cloud band west of
Cairns.  Check out the development here:
http://www.maths.monash.edu.au/~robert/Weather/2001_06_19/mg.html

Just looking at my archive of sat pics, there was a nice morning glory
on the 17th/18th.  Check it out here:
http://www.maths.monash.edu.au/~robert/Weather/2001_06_17/mg.html

This latter one seemed to form from the east and west coast sea breeze
interaction over the peninsula.  

However, the curved cloud you pointed out yesterday seems to be the result
of a downdraft from the blob of cloud in the first frame, on the coast
between Cairns and Townsville.

Just did a dual vehicle storm chase. Started at 12:15pm today(Wednesday) with 
a bike ride to the Deception Bay foreshore to get a look at some nice Cu's 
offshore. They looked excellent. Also noticed a column of pyrocumulus rising 
on smoke from a bushfire. Didn't look all that special at the time, so I rode 
towards a hill with a view to the west on Boundary road. From there I could 
see that a whole lot of Cu's were forming everywhere. Some were breaking the 
cap, others leveled out on top underneath the cap. Looked back across at the 
pyrocumulus and was astonished to see the highest column of pyrocumulus I 
have ever seen. 

It was levelling out at the cap a bit, with a bit of anvil forming, but the 
main updraft also broke the cap went skywards at least to 30,000 feet. The 
billowing clouds looked like a volcano eruption. Headed home, had a look at 
the radar and a chat to some people on #weather. Ben Quinn went to look at 
the pyrocumulus when I told him about it, and he was astonished by the size, 
and headed off to get photos. I also jumped in the car and went and grabbed a 
100 ASA film, chucked it in the camera, and drove to the top of Scarborugh 
near Newport Waterways to get photos. I have some pretty good ones(I hope). I 
will have to wait to get them back from the photo shop though, so you won't 
see them today.

Also on the way home i noticed that one of the Cu's i had been watching 
earlier had developed into a thundershower cell, and moved towards 
Caboolture. No time to chase it though :-(. Pretty exciting for a winter's 
day, and a bit better than the last few weeks. I'll post the pictures as soon 
as I get them back. Ben Quinn should have some from his digital camera too.

Hello,

I saw that pyro too - short on film in my good camera but got a fair shot
of that and a good shot of the small t'shower cell with the digital.

http://www.schools.ash.org.au/paa/images/pyro.jpg
http://www.schools.ash.org.au/paa/images/scelljun.jpg

It certainly was the most awesome, tallest cloud I have seen built by the
fire under it, and the growth! - it was truly billowing at a great rate!

I am sorry now that I didn't get more film for my good camera (nothing like
timing - first time my camera has been film-less since I've had it...) so I
could have had some zoom to frame it better....and go back to my vantage
point, off Toorbul Point Road...

Will be great to compare these with others...I was lucky to be on the spot
today - both of these were near my part of the world.

Note there was another big pyro in the Sunshine Coast hinterland -
Beerburrum perhaps.

Sel.

hi guys,
a pleasant surprise today. at about lunchtime we had a massive deluge in
currumbin (southern end) near border. there was a few rumbles of thunder.
one of them sounded pretty close. there was some pea sized hail that fell
for about 5 minutes, some very strong gusts which messed up the shop
blowing paperwork all over the place.
am very interested in seeing the rainfall stats. it poured for about half
an hour flooding some roads around the local area. am not sure on how
widespread that storm was. if anyone happened to save any brisbane radar
around lunch today, please let me have a squiz. ummm tahts all
cyas

Hi David, all

WOW!!!!!!!!! I think i can safely say today was a day i will remember for
many years to come.  I'm going to write up a report on BSCH with a series of
photos, but for now i have uploaded a shot of this truly spectacular Pryo Cb

http://www.bsch.au.com/temp/pyro1.jpg

Driving towards it was like driving towards and erupting Volcano!

And also a storm with excellent structure late in the afternoon

I must say that I don't comment on photographs  but that is sensational Wow 
Well done. Something to look out for - fires in winter where there is cold

Hi Keith.
You should see a lot more than I saw with a 10" viewer.Also the large
baroclinic cloud band across the top end of the NT has started to produce
patchy rain which is most unusual for this time of the year,what can you see
up there Paul M,.regards Clyve H.

Hi guys,

I am truly jealous of this shot. It would have seemed absolutely awesome to
watch it's growth and just how powerfully turbulent it looks. Volcanic is a
good description, and maybe quite a coincidence since there has been some
discussion about a dormant Mt Warning recently. Can't wait to see further
piccies of this pyro-cb.

Howdy Clyve,

Large cloud mass to SW - actually thicker yesterday afternoon. Looked like
it was going to rain. As soon as the sun sets - thick scuddy cloud screams
in of the ocean.

The cloud seems higher then the satpics indicate - very "mackerel" type.
Certainly was very dark to the South......

Very low moisture levels in the lower atmosphere - any precip that falls
would probably be virga I would suggest.

Rgds, Paul.

even during the big bush fires we have had down here in Vic.  You can almost
see the movement in the cloud.

Absolutely awesome.

Wow, what a way to kill a discussion.  I think all Peter was trying to do was start a 
discussion on developing some standards for reporting storm chases on the 
web. A noble aim I would say.  I think Peters mail was "a personal suggestion" 
with the aim of starting some discussion on the topic, ignoring any percieved 
confusion between ASWA members and the "public at large" on the list.  So how 
about a discussion on standardisation, no...lets say "best practice", for storm 
chase reporting on the web by anyone on the list (ASWA member or not).  
Seems reasonable to me.

Hi Rhett and all,

I have read through this and also commented but with Rhett's e-mail 
reconsidered another possibility. Perhaps one way of standardising the 
whole process of maps for instance is to have a separate site maintained by 
all with maps that can be referred to by all sites. In other words, reports 
links to this site for maps so that people who read about Australian storm 
chases can refer to a common map. It also allows for chasers to share the 
burden of maintaining maps. I don't recall all of Peter's ideas but perhaps 
this is a possibility.

Having said this, I hope people understand just how much time and 
enthusiasm is required in writing reports let alone building a site. It 
requires incredible discipline to maintain a site and I suppose feedback 
mentioned by Matt Smith can help or discourage the want of continuing at 
any particular time. Time is also the essence in this modern busy world.

Just my thoughts. I would say that if this concept was to continue, then a 
separate e-groups committee be set up with people who would like to take 
part. This list is perhaps not the ideal place to send e-mails in regards 
to the setup once a decision has been finalised.

So any ideas?

Hi all

Thanks Jimmy, Andrew, Chris!

I've uploaded the full series for the Pyro (10 photos)

http://www.bsch.au.com/photos/ben/200601_01.shtml

They're in order of when they were taken as i drove north along the highway
and then east towards it

In the report there are photos from Greg Curtis and Jason Rainforest of
storms late in the day

http://www.bsch.au.com/reports/20_06_01.shtml

The storm Jason got at Pimpama (between Brisbane and the Gold Coast) had
excellent structure, lit up by the setting sun!

http://www.bsch.au.com/lem/LemG/Wx/Chase_Images/200601/200601-1657-05.jpg

Also for those that haven't heard thunder for a while Jason has included 4
thunder audio clips

Hi Rhett,

I was going to post this privately, but I thought I'd send this to the
list, as I think a few things were miscommunicated.

I didn't want to stop the discussion, only I thought I would be doing
everyone a favour by telling people that there is no point in discussing
ASWA's involvement because ASWA is currently not involved in any chase
reporting as such.  But rather, discuss this suggestion at a personal
level for those people who have websites and do put up chase reports to
talk about it and they can decide whether or not they want to
standardise their reports personally, or do them differently to everyone
else.

Regards,

Anthony Cornelius

hi mark,

there were a lot of emails, so i only skimmed, but the gist is that the
inversion due to the high is creating a temp/moist boundary somwhere between
the high altitude station and the low altitude station? I havn't really
considered this and, considerng the huge dew point spread, certainly would
explain it.

Curious though because, the air is always very dry up there to start with.
And you don't need a strong high to get a valley fog forming but is what you
would need to get the transition layer down to below the 850mb. Though, i'm
sure a 20C DP spread is certainly due to that, i would like to see some data
for a fog forming in, say a little ridge of high that is quickly swept
away...Would make for an interesting contrast.

cheers, lyle

BTW, he was almost 20km away when he took that photo.(That's assuming you 
took it from near Redcliffe). I don't think anything will match that Pyro in 
a long time. I was watching it for a long time hoping to see lightning, but 
unfortunately no luck on that front. Hopefully today will be just as good.

I have some ones taken across the water looking towards the fire. Mine are 
more wide angle so you see the whole Cu. You can also see where the Cu had 
flattened out along the cap, and then broken it. That's assuming they come 
out. No photo would do this Cu justice, you just had to be there! 

David

P.S. Ben, if my photos come out, do you want to add them to the reports on 
the BSCH page. If you want I could give you a report on how it first 
developed and turned into the monster while I was riding.

 Were there any extensive snowfalls in Victoria during that 1995 cold spell?
Similar situations in the South Island have resulted in some (though usually
brief) heavy snow events, mainly in Central Otago and South Canterbury's
Mackenzie Basin. (both areas are notorious for cold air pooling and freezing
fogs) Even in the central North Island moist north to northwesterly winds
brought snow to unusually low levels at least once - 19 July 1995. (not very
long after the Victorian event you mentioned) On that occasion the
northwesterlies were preceded by an icy southerly blast on the 17th which
had already dusted higher ground in that area, and then a ridge on the 18th
which didn't allow any warming before the moist air moved in.

There was some snow at relatively low elevations - the snowline was
about 500 metres IIRC - the sort of snow that one might expect to see
2-3 times in a normal winter. (1995 was a good winter for cold 
outbreaks in southern Victoria, so 10 July didn't stand out as much
as it might have done in other years).

I would have been interested to know if there was any freezing rain
with this event - if it was ever going to happen in southern 
Australia, it would have been the right situation, but there were no
observations in the critical elevation band (between about 700 and
1100 metres, below the inversion).

Do the South Island inland valleys ever get freezing rain?

Hi Jane and everyone

Just saw the channel 9 midday newsbreak and it had a report of a
mini-tornado (hate that term so much it isn't funny - mini tornado should
only be used in reference to the funnel that forms when you empty the
bathwater out hehe) hitting some small town just outside Ballarat. Saw some
brief footage and it looked as though it did a fair number on the buildings
etc that it hit.

It could have been straight line winds but the set up was there imho for a
tornado - strong low level winds and shear (front came in from the west with
40-50kmh northerlies in front of it) so the SRH would have been pretty high.
WE could see a similar thing happen with the small front coming up from the
SW at the moment as well - though the directional shear won't be there as
much - can only hope I suppose :-)

Got a very nice heavy downpour here last night - was great to see - would
have been easily pink on radar at its heaviest. I am close to the CBD which
got 13.4 I think so would have got pretty close to that

Chris

It's written up at 
http://ballarat.yourguide.com.au/detail.asp?
class=news&subclass=local&story_id=58417&category=general%20news
where it is described by BoM as "a severe wind squall" and by the owner 
of a damaged house as "It looked just like a tornado."
They avoided that "mini" word, though.

Hi all,

The current patterns make for interesting synoptic charts. The
sub-tropical ridge is so far north that it's like the roaring 40s have
come up with it - which is why it is so bloody windy!

Hopefully this will mean a significant cold snap with in the next
fortnight or three weeks. Because of the above there is a great mass of
very low thicknesses on all the models welling up to the south - we just
need a good low to develop and sling it all up this way. The high belt
has certainly made way for them.

I can't recall seeing the ridge that far north for this sort of extended
period for a good few winters!

Ever hopeful.

Andrew.

From the latest advisories it would appear that Tropical Storm Chebi 
could be setting Hong Kong in her sights - although it is a bit early to 
say definitely yet.
For those wanting to follow the progress (during Oz's boring winter) I 
have gathered the usual collection of links and info on my page at 
http://www.drdisk.com.hk/cyclones.htm and will keep on updating.
The doctor has given me a week at home after a trip to the hospital, so I 
should be able to keep track of it far better than usual.

The severe weather folks on the 26th floor are examining the data.
>From watching over their shoulder it looks like:

* the "event" had virtually zero analysed CAPE
* the reflectivity signature of the convection (at all tilts)
  shows nothing outrageous
* the low-level shear was fairly large (I think aircraft data showed
  ~50 knots of flow around 850-700  

I am not sure whether I would be able to separate strong straight-line winds
from an equally strong surface circulation in the dark with rain
present.  The data certainly do not show a high probability of a "coldie",
but the shear profile suggests to me that you can't rule it out
either.  Can someone residing in or around BLT do a damage survey?

Cheers, Harald

Hi Andrew,

I'm glad you mentioned it first :) I was scared of jinxing it. Seriously
though, it would be nice to see some more cold air moving in. I noticed on
gasp and avn that it does look like the possibility of something developing
later this month in the south east, with this setup. Yeah, its been a while
since I've seen things like this, then again, it has happened over short
periods over the last few seasons and then gone again, so...it better not
this time! :)

Hey All, yeah I live in this cold ol' hell hole called ballarat, I was too 
busy playing with my new PC, heard it on the radio this morning, it hit 
delacombe, desttroyed a carport, threw a few roof tiles and knocked over a 
few fences, yet to go have a look at the damage, prob none now, I some how 
doubt it was a 'nader, prob a microburst, because there was some very heavy 
intense rain squalls that did move through here yesterday avo, at about 5pm, 
heavy rain, had 5mm in 10mins. Not bad for a CF that wasn't really expected 
to do a lot, although Clyve did say there was a small cold pool right behind 
it, I looked at the sat pic b4 I left tafe yesterday at 3:40pm, didn't look 
like much, but then on rob gell's weather report, it appeared as though the 
CF intensified as it made landfall, became more defined. anyway all in all 
not bad. Still have drizzly weather now, total wet grey sky.

Cheers LEs Baxter

Andrew,

Yes the models are hinting at this upwelling of cold air, but the last two days have seen the encroachment of this deep low situation being pushed back due to the high maintaining a ridge back towards WA. Hopefully this breaks down sometime soon and as the model predicts a new high cell with a fetch to south of 50S and a strong low slingshot some sub-530 air with strong minus temps at 850HPa our way. My eyes are definately glued to the models in hope.

Cheers
Andrew Godsman

This reminds me of the event at Fairfield in Sydney a couple of years ago...
very localised damage, but consistant with something in the F0 range.... but it
was hard to tell what exactly caused the damage! (Straight line wind etc). Why
do these events occur in the middle of the night when know one can confirm/deny
anything ! :)

What about if the weak, localised damage was the result of a gustnado or
even a landspout?
Can you tell that I've been reading the latest 'NSW Lightning Bolt'??     :)

down sometime soon and as the model predicts a new high cell with a fetch to
south of 50S and a strong low slingshot some sub-530 air with strong minus
temps at 850HPa our way. My eyes are definately glued to the models in hope.

Hello,

Great all!

I think your pics really captured the event!

Makes me sorry I didn't do a chase to get closer - working unfortunately.

Terrific!

Sel.

Hi all.
The upper cloud band across the top end of the NT looks impressive,appears
to be associated with a marked strengthening of the 500hpa -300hpa flow from
the northwest which may be responding to major cyclogenisis west of NZ,all
in all I like the look of it.regards Clyve H.

Of interest is the enormous field of cold air to the west of Australia
atm, and also the cross-equatorial flow that is being drawn into it.
Will it manage to hold it's latitude as it moves east?

<DIV><FONT face=Arial size=2>To some extent I agree with your explanation , 
however I would not go as far as to say it does not occur in Australasia,as I 
see it if rain falling from what ever source i.e. mid level cloud which may

freezing layer and is cooled below its freezing point, I would presume it to be 
supercooled in its water state. An interesting argument can be put as to 
supercooled precipitation from orographic origins over the Australian Alps (I 
have seen it ) that is freezing drizzle, could this not be presumed as 
supercooled rain, such precipitation freezes on impact with anything.Back to the 
case of freezing rain, there have been rare occasions of supercooled rain 
falling (large droplets) over the higher Australian Alps and freezing into clear 
ice on contact with the ground. Also , the south island of NZ as you are aware 
have some interesting localities such as Alexander, I have also read of rain 
falling into this rather dry valley after a frosty night with the lower levels 
recording temps close to -10c and the rain becoming supercooled and freezing 
into clear ice on impact with the very cold land surface. Is this not freezing 
rain?.In the northern hemisphere tropical maritime air invading localities such 
as the mid latitude regions of the USA ahead of active warm fronts initially 
produce snow at higher levels, which melt in a layer of positive temps above 
very cold air near to the surface,in so doing this rain becomes on occasions 
supercooled, especially if the rain is very pure with very low amounts of dust 
ect,on reaching the ground this type of precipitation freezes instantly to 
produce the well known ice storms we sometimes here about.</FONT></DIV>

Hi,

the set-up sounds like a perfect situation for a surface convergence vortex,
especially based on the fact the wind speeds were not that great.

Hi.

I would be carefull about saying it does not occurr in Australasia, as I'm
sure it has at one point in time or another. Though, as you said, the
climatoligical set-up is more prime in the Northern Hemisphere.

Just as weather weannie point, we had freezing drizzle here last winter. It
was really cool because, as all of us weather freeks secretly want chaos,
freezing rain seems to be one of  the biggest harbringers of pile-ups and
what not. We nearly droe through a shop window.

I'm not sure if this supports your case of 'no freezing rain' unless you
mean the rain hit the ground and then, some time later, froze?

Cheers, Lyle

Hi Clyve,

you are definatly correct - freezing rain does not need to originate as
snow, it just has to be supercooled droplets

  Blair, freezing rain does not occur in Australasia. It is a phenomena of
the cold continents of the northern
  hemisphere. By definition freezing rain is super cooled water that turns
to ice on hitting the ground.
  I have seen rain in sub zero temps in new Zealand but it was not freezing
rain, rather it was rain falling into
  frosty conditions. It produced icy conditions for a little while.

  <DIV><FONT face=Arial size=2>Hi Steven.</FONT></DIV>
  <DIV><FONT face=Arial size=2>To some extent I agree with your explanation , 
  however I would not go as far as to say it does not occur in Australasia,as I 
  see it if rain falling from what ever source i.e. mid level cloud which may 
  originate as snow then fall through the melt layer and then re- enter a sub 
  freezing layer and is cooled below its freezing point, I would presume it to 
  be supercooled in its water state. An interesting argument can be put as to 
  supercooled precipitation from orographic origins over the Australian Alps (I 
  have seen it ) that is freezing drizzle, could this not be presumed as 
  supercooled rain, such precipitation freezes on impact with anything.Back to 
  the case of freezing rain, there have been rare occasions of supercooled rain 
  falling (large droplets) over the higher Australian Alps and freezing into 
  clear ice on contact with the ground. Also , the south island of NZ as you are 
  aware have some interesting localities such as Alexander, I have also read of 
  rain falling into this rather dry valley after a frosty night with the lower 
  levels recording temps close to -10c and the rain becoming supercooled and 
  freezing into clear ice on impact with the very cold land surface. Is this not 
  freezing rain?.In the northern hemisphere tropical maritime air invading 
  localities such as the mid latitude regions of the USA ahead of active warm 
  fronts initially produce snow at higher levels, which melt in a layer of 
  positive temps above very cold air near to the surface,in so doing this rain 
  becomes on occasions supercooled, especially if the rain is very pure with 
  very low amounts of dust ect,on reaching the ground this type of precipitation 
  freezes instantly to produce the well known ice storms we sometimes here 
  about.</FONT></DIV>

Hi Steve,

When Clyve talks about melting snowflakes, he is implying that the flake
completly becomes a liquid droplet. Then enters a sub-zero layer and, if in
this layer long enough, can become supercooled. I think your getting
confused with nucelation and thermodynaimc heat exchange. Your correct that
the rain drop would have an ice nuclei in it but, when in the freezing
layer, it is not nucleating but rather cooling.

Supercooled droplets do not develop high in the atmosphere, it's more of a
mid-atmopsheric phenomena though i'm sure there are exceptions but this is
why upper level clouds are usually ice clouds. This is because homogenous
ice nucleation of pristine water will be significant at tempretures
below -18C - ie no ice nuclei are required to form an ice crystal. It is
also why a thunderstorm will suddenly glaciate when ice crystals form up
high and seed the supercooled droplets below.

The absence of ice nuclei will inhibit an ice crystal forming in warmer
tempretures but this is rare as there are nearly always some ice nuclei
about. Also, keep in miind that precipitating clouds nearly always transport
air from low levels to higher levels, so it's the low level analysis of
nuclei that is important, not the high levels - generally.

Here's an extract from a presentation I did on something close to this
topic;

* Can An Ice Nuclei Form? Check Coldest Cloud Top Temp;
    - 4oC or warmer No Ice Nuclei
    At -9oC Mostly super cooled water
    At -14oC Some Ice Nuclei
    -18oC or colder All Have Ice Nuclei

* Bochierri (1980) and Young (1978) Noted that 30%-40% of freezing rain
events occur without a layer above freezing in the sounding

There is no doubt that most precipitation in australasia is warm rain but,
in the southern parts (NZ, SE Aus etc) i imagine freezing rain is not too
uncommon in the higher elevations. However, most times the clouds are seeded
so we get snow. The classical synoptic setup would be rare, that is to have
a warm layer above a cold layer, as is common in the autumn here in the US.
But, supercooled droplets not nucleating would not be rare.

I must say i have never observed 'freezing rain' in australia but i have
seen a lot of riming, indicating supercooled droplets do exist. Infact,
after the big storm in may 2000, there was 5cm thick rime on top of Mt McKay
(Victoria), i have a photo if your interested. Next time you go skiing, look
at the poles around you after a storm, i'm sure you'll see riming as I've
seen it a treble cone, cardrona and Broken River in the south island.

cheers, lyle

Hi all.
A good example of a major jet streak extending from the Indian Ocean to
Tasmania today,also note the wave structure along the north-eastern edge
extending for hundreds of kilometres northwest to southeast. The cloud band
seems to have peaked and will possibly start to decline today...good stuff.
regards Clyve H.

Hi all planet watchers.
I have often been intrigued by the atmospheric physics of other planets,one
in particular is the cloud developments on Mars,its interesting to note that
some believe that apart for microscopic dust as nuclei also small ice
crystals also play a part in the base development of carbondioxide cloud on
that planet. On occasions large areas of carbondioxide ice cloud are seen
and some close ups appear to show falling precipitation and residual
anvils.Carbondioxide snow however will only reach the surface as long as the
temperature remains below minus 125c otherwise it evaporates very rapidly.
It would also be interesting to observe the occasional convective pulse near
to the equator of this planet which show up as rather bright white
cumuliform splotches not unlike small convective congesting cu here on
earth...regards Clyve Hebert.

Steve Williams... the hole you dig keeps getting bigger :-) ..... Anyway,
thought it time to consult some Meteorological Glossaries...

Anyway, according to the American Meteorological Society..

"freezing rain - rain that falls in liquid form but freezes upon impact to
form a coating of glaze upon the ground and on exposed objects. While the
temperature of the ground surface and glazed objects initially must be near
of below freezing, it is necessary that the water drops be supercooled
before striking. Freezing rain frequently occurs, therefore, as a transient
conditions between the occurrence of rain and ice pellets (sleet)"

And the UK Meteorological Office..

"freezing drizzle/rain - supercooled water drops of drizzle (or rain) which
freeze on impact with the ground or other objects to form glazed frost or,
in the case of smaller droplets ... rime."

The supercooled droplets can come about from two somewhat "separate
processes", being warm rain falling through an inversion into a cold near
surface layer (pretty rare in Australia), and from clouds deep enough to
precipitation, but with insufficient freezing nuclei or too warm temperature
to support the formation of ice crystal (indeed very common in Australia).

Freezing drizzle is very common in alpine Australia, where precipitation
stratus/stratocumulus is too shallow to support freezing, often leading to
thick rimming. This is not fog, as you can see and feel the droplets, and
indeed get saturated while skiing.

Personally, I have seen freezing rain only once in Australia, at Lake Mt
(elevation around 1400m) in the mid 1990s. It was a cold NWerly day, with
nearly continuous predominately orographic precipitation. For most of the
day the precipitation was snow, but for about 1/2 an hour it was rain. Of
course, falling on snow, this made for a slushy surface (Australian snow is
almost always slushy and near 0C), but on the supercooled road it formed a
treacherous layer of ice... On the drive home (in four wheel drive), the car
I was driving span sideways, and I continued in a slow sideways slide for
around 100m before coming to a halt. Fortunately, the road was straight and
very wide at the point.. but I so scared myself (and a friend) that we were
readying to jump out the car door, just prior to the car stopping. A little
further on, we came across someone less fortunate who was in the ditch.

I recall once reading about a major ice storm in that hit Perisher in the
1990s, closing the lifts for a period, but can't recall any further details.

Anyway, I would expect "proper" freezing rain to be relatively common
(though not very spectacular) in some of the bigger alpine valleys in the
snowy mountains, and probably also in parts of Tasmania where exceptionally
cold air can be trapped and over run in winter.

Cheers,

David.

This was definately a case of the rain droplets freezing when they came
into contact with the ground and then into contact with the ice layer.

Hi All

Although I couldn't comment on the technical nature of how freezing rain
occurs I did have the pleasure of experience such a conditioin in the UK.

I happened to be at my parents house in the Mendips (abour 800m above sea
level) South-West England near Bath. The freezing rain occured over the
christmas period, for the whole period we had minimal snow fall however
over one night freezing rain must have occured. When we woke up in the
morning (probably sub zero) the roads, fields and even trees were covered
in approximatley 1 inch of CLEAR ice. I had never seen anything like it
before and doubt if i'll ever forget it. I have a few photographs that i'll
scan in over the weekend and post next week. It was quite amazing. During
the day there was some fog around which must have been freezing fog as the
ice layer seemed to build up over the day, although i couldn't specifically
say by how much. The ice lasted well until the next day. From what i
remember (this was about 5 years ago) a lot of the power lines came away
from their fixings due to the weight of the ice on them.

Sorry this isn't very technical but it was an experience to remember. Would
love to see it again if it does occur in Ausralia.

Simon

Hi Simon,

Look forward to seeing the pics of the freezing rain/ice. And Jane, thanks
for that cool sat pic of that cold air pool west of WA. Watching it with
interest.

COLD AIR FUNNELS
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
1201 PM CDT THU JUN 21 2001

...COLD AIR FUNNELS POSSIBLE ACROSS SOUTHERN WISCONSIN...

COLD AIR FUNNELS HAVE BEEN SIGHTED IN GRANT COUNTY IN SOUTHWEST
WISCONSIN. THESE WERE REPORTED AS HIGH IN THE CLOUD AND NOT CLOSE TO
TOUCHING THE GROUND. THERE HAVE BEEN NO REPORTS OF THESE FUNNELS AS
OF YET IN SOUTHERN WISCONSIN...HOWEVER CONDITIONS ARE FAVORABLE FOR
THEIR DEVELOPMENT.

GENERALLY FUNNEL CLOUDS DEVELOP AND OCCUR IN CONJUNCTION WITH WELL
DEVELOPED AND INTENSE THUNDERSTORMS WHICH HAVE FORMED IN A WARM
MOIST AIR MASS.  THUNDERSTORMS OF THIS VARIETY AND INTENSITY NEARLY
ALWAYS FORM ALONG AND SOME DISTANCE AHEAD OF A STRONG COLD FRONT.
WHEN FUNNEL CLOUDS ARE IN ASSOCIATION WITH THIS TYPE OF THUNDERSTORM
THEY FREQUENTLY DIP TO THE GROUND AND HAVE SUFFICIENT FORCE TO
DESTROY EVERYTHING ALONG THEIR PATH.  A FUNNEL CLOUD THAT TOUCHES
THE GROUND IS CALLED A TORNADO.

AN ENTIRELY DIFFERENT CONDITION PREVAILS OVER WISCONSIN TODAY.
THERE ARE NO STRONG COLD FRONTS IN THE AREA.  THERE IS LITTLE
POTENTIAL FOR INTENSE THUNDERSTORMS.

RESEARCH STUDIES OF FUNNEL CLOUD OCCURRENCES DURING THE PAST
SEVERAL YEARS INDICATE THAT A SOMEWHAT DIFFERENT SPECIES OF FUNNEL
CLOUD FORMS WHEN WEATHER CONDITIONS ARE SIMILAR TO THOSE OF TODAY.
THESE ARE CALLED COLD AIR FUNNELS AND ARE NOT AS VIOLENT AS THOSE
ASSOCIATED WITH WARM AND HUMID CONDITIONS.

THESE STUDIES OF COLD AIR FUNNELS SHOW THEY RARELY DO ANY DAMAGE.
THESE FUNNEL CLOUDS NORMALLY PROTRUDE A FEW HUNDRED FEET DOWNWARD
FROM THE PARENT CLOUD...ROTATE OR SPIN LIKE A TOP...AND LAST A FEW
MINUTES BEFORE DISSIPATING.

REPORTS OF SMALL FUNNEL CLOUDS MAY BE EXPECTED OVER SOUTHEAST
WISCONSIN THIS AFTERNOON. WARNINGS MAY BE ISSUED IF ANY OF THEM
TOUCH THE GROUND.

Wow! Maybe a lot of the funnels "we" see are actually these cold air funnels
which are never going to touch down and do any damage? Gotta agree that I've
never seen or heard anything like that. Every day is a school day....

Good question - it certainly looks like a TC in the satpics, and given
JTWC's tendancy to under estimate wind speeds in midget southern hemisphere
systems, it may be more intense than they think - it has a distinct eye
feature in the satpics.

Some satpics of TC 21 S are at
http://users.ace-net.com.au/~carls/currenttropical.htm along with some
images of Typhoon Chebi now in the Bashi Channel and Tropical Storm Barbara
now in the North Central Pacific. Click on the thumbnails for the full size
images.

Hi,

I was wondering if anyone knows of any site or software that will plot the
METAR's for australia? I can only seem to find data products rather than
real time images?

Hi,
My definition of freezing rain was based arround the American version. The
UK definition is much
broader. I have never considered rimming to be freezing rain. I have to
agree with Lyle, freezing
rain could occur at high elevations, particularly the southern Alps.

 Are we witnessing the return of El Nino? All the models seem to be placing
anticyclones in lower latitudes, with westerly quarter flows (maybe allowing
for more cold outbreaks) predominating over NZ and throughout the southern
parts of Australia . Recently I heard a NZ MetService spokesperson say we're
still in a weak La Nina, but this current weather pattern seems to be more
typical of El Nino.

Hi Ben,
The Australian Bureau's Tropical outlook notes are saying the majority of
models predict neutral conditions with only a few going for El Nino, at
least in the next 6-9 months.
In terms of patterns, my understanding is that you can get just about
anything whether El Nino is operating or not. We do have very intense
depressions operating in the southern ocean at the moment bringing all those
gales but I think it's a bit early to say if this means a reversal of La
Nina or the neutral pattern we've been having for quite a while now. I could
be wrong of course..there are plenty of people on the list with far greater
knowledge than me!

David et al,

There is an instance of freezing rain on 30/7/74 at Mt Buller 
and Falls Creek, and most likely other locations at a similar 
altitude; this is detailed in a paper, Meteorological Note 
80, by G.H.Sabin. In this instance the freezing rain was due 
to one of those somewhat elusive occurrences, a warm front, 
which would provide the ideal set-up for such a phenomenon in 
the alpine regions. At Mt Buller this persisted for around 10 
hours; and it is stated that a coating of clear ice covered 
everything on the mountain. Local residents stated that 
freezing rain was rare, and that they could not recall a 
situation  of the duration and intensity as this occurrence.

Hi Jane

Check out this site which shows an animation on how this vortex street is
formed:

http://www.mcef.ep.usp.br/staff/jmeneg/cesareo/Cesareo_Page3.html

Basically, the island acts as a barrier in the flow.  Due to the stability
of the flow, there isn't much vertical movement, and so the airflow
primarily deviates _around_ the island.  On the downstream side of the
island, the flow is separated, and forms a succession of vortices called a
von Karman vortex street. 

Here's some more cloud examples:

http://www.eng.vt.edu/fluids/msc/gallery/vortex/guadb.htm
http://climate.gsfc.nasa.gov/~cahalan/KarmanVortices.html
http://www.ocean.washington.edu/research/gfd/cloud/clouds.html

Basically, any search under 'von Karman' on the net should bring up a
plethora of stuff.

Hi all,

Not exactly weather I suppose, so apologies for the slightly off topic
post, but I thought people might find this interesting. A strong
earthquake was observed near the coast of southern Peru at 2033 UTC (6:33
am AEST) this morning, given a preliminary strength of 8.2 on the Richter
Scale, which has generated tsunami wave activity. Arica in Chile has
observed a peak to trough height of 2 metres with a period of 15 minutes. 
A tsunami warning is current for most of the west coast of South America,
with a watch current in Mexico and French Polynesia. At the present time
it is not known if a pacific-wide destructive tsunami has been generated,
so Hawaii is only on stand-by. Will find out in the next few hours of
course. 

Cheers,

Jonty.

Afternoon all from the windy city,

Even if you weren't around for the 'wind trousers' last year in Italy,
you've probably guessed that we are talking about tornadoes...(this is
waht you get via the translation of the word 'tornado' through
AltaVista's translation engine.

I've been hunting for new sites to add to the MSC Cafe (
http://www.stormchasers.au.com/forecasting.htm ) & today I have found
another reference to 'Wind trousers' on a Bavarian site.  I've already
run it through a translator so it's sort of in English
http://babelfish.altavista.com/urltrurl?lp=de_en&url=http%3A%2F%2Fwww.bl
itzwetter.de or if your German is up to scratch then go to
www.blitzwetter.de .... to see the frequency of 'wind trousers' in
Germany during 2000, click on the link on the left "Tromben 2000"

If you're into Vortices & Fractals, then the 'Why is it so?????' page
has some new links at http://www.stormchasers.au.com/why.htm
with thanks to Robert Goler & his amazing library of links!!
Enjoy!

It's not very off-topic.
I think tsunami = weather.
If pyrocumulus started by forest fires qualifies as weather then tsunami 
started by eathquakes also qualify as weather.
We (many of us) shall be fascinated to see what develops as it travels 
around the world.

Hello Dean

We did get storm conditions here in Strahan but it was today not
yesterday. At 12noon one of the fiercest thunderstorms past through
here. Storm winds, hail, torrential rain and the power out. The storm
actually ambushed us as it was proceeded by a couple of hours of
showers.

WOW there are some great shots in those pages!
Makes me want to go back there myself. (I did a little storm chasing 
there in 1978).
Actually, I am looking forward to some good write-up about some of those 
shots (not putting any more pressure on of course!).

Well not exactly. I was just wondering how you would build a sensor to
detect that you are actually in a tornado. Updraft detector maybe?

Also after a careful search I was unable to find anything that was useable
for anenometer cups, so i have reverted back to my original idea of half
pingpong balls. I was just wondering if anyone here is familiar with plastic
moulding. I was going to get some tough PVC plastic sheeting, heat it to 250
degrees in the oven, and then use half a ping pong ball as a mould. I did it
once at school for some sort of bowl we made in manual arts. Just wondering
how to stop the PVC sticking to the ping pong ball. Thanks,

David

G'day Chas and All,

Yep, we were hit by the storm yesterday at around
13:30 in Devonport. I've captured some screen shots of
the system - looked like a squall line. Some trees
were blown down in the park across the road from us.
Noticed a few fences and trees down on the way to work
this morning. Radio news reports damage to houses and
powerlines. Any damage down your way Chas?

Andrew.

Still blowing from the west. There is now a chance of flooding here in

notes received from Kevin Parkyn at the BoM in Melbourne re the Ballarat
event - with many thanks to Kevin for letting us know.
............................................
<snip>

From all accounts so far the damage is consistent with F0. Spoke to a chap
who lives about 300 metres from the damage site who has an AWS in his
backyard. He'll be sending in the reports from his AWS this week hopefully.
The signature from the 3-D radar shows a cell of deep-convection near
Ballarat at the time of the incident. Middle level capping of most cells
occured around 4km, however the cell in question managed to break this
resistance barrier and shoot up to 6km, but only magaged this feat for about
10 minutes. Bouyancy was nothing spectacular, however the extra vertical
extent probably allowed middle level winds to mix to the surface. I suspect
that negative bouyancy played a part adding to the already strong WSW winds
aloft (about 40-50 knots).

Directional and possibly speed shear existed in the low levels right near
the passage of the front on which the cell formed. Consequently a short
lived tornado is not out of the question, however the damage is consistent
with that caused by straight line winds.

Hi all,
VERY warm in Blackheath today. I cannot recall having so many mild days in
June. I recorded 15C at my place and the official AWS at Mount Boyce
recorded 15.6C (a site very close to lots of bitumen and the afternoon sun).
Quite amazing for this time of the year. You could easily forget that it is
June. I think Katoomba's record is around 17C for June so maybe around 16C
here. Usually our temps are in the 5 to 10C range at this time of the year.

This case hints at one (of many) severe weather forecast dilemmas.
Not many of the classic severe parameters were in place for this
event.  There was little in the way of CAPE, lapse rates, moisture,
cyclogenesis etc.  The only ingredient of note was the low-level shear. 

My question to the group:  how can you pick the cell (cells - there might
have been more) that dumps (dump) stronger flow at the surface over an area
of 90 x 300 m.  You had many cells to choose from...

Les,

Thanks for the links to the noctilucent cloud.

Thought you might be out chasing...given the current UK forecast (as set out 
on the BBC website). Looks somewhat more interesting than most of Oz at the 
moment.

Let us know if things get "paticularly interesting"...

Patrick

Hi all.
Another synoptic/broadscale sized 'Hockey stick' cloud band (im sick of the
description northwest cloudband!)approaching west Aus, similar but not as
big as the one several days ago.Also a large field of cold air south of 40
degrees over most of the ocean south of Australia,looks like  the west and
south of Tasmania will be the place to be for consistent
showers/rain,although conditions look better for the southeast of Aus this
coming Thursday/Friday with  the possibility of a more active cold
front....regards Clyve Herbert.

Hi Jonty.
I was reading a description of a tsunami recently which claimed that the
ocean shock/wave moves at speeds of up to 500kph+ although such a wave slows
down over shallow water but with a corresponding energy transfer which
results in an increase in the wave size! anybody confirm..Clyve H..

That is pretty much the textbook.

The energy of the wave only transfers to significant height when interaction
and resistance with the ocean bottom results in energy being pushed upwards.

The wave bottom then is retarded that much that the top which moves faster
spills over ( the wave breaking )

Nice and balmy in Sydney too. But very dry. Seven Hills is having its driest
June (3.8mm) since 1962  and the 3rd driest on record.

HI all..
<p>Was doing some searching around for info on the Newcastle Earthquake
and came up with this part of an article explaining the pure amount of
Energy these produce. Quite interesting to read..
<p>Dave
<p><A HREF="http://www.ncc.nsw.gov.au/library/eqdb/earthq3d.htm">http://www.ncc.nsw.gov.au/library/eqdb/earthq3d.htm</A>
<p><b>There are a number of methods of describing the size of an earthquake.
The most commonly used scale is a numerical scale called the Richter scale.
About 700,000 Richter magnitude l earthquakes occur each year on earth
(earthquakes). Each one of these is equivalent to about 0.5kg of TNT exploding.
A Richter magnitude 2 earthquake is 10 times more intense than a Richter
scale 1 and a Richter scale 3 earthquake is 100 times more intense than
an Richter Scale 1.</b>
<br><b>&nbsp;</b><b></b>
<p><b>About 300,000 scale 2 and 49,000 scale 3 earthquakes occur on earth
each year. Richter scale 4 earthquakes are 1000 times more intense than
a Richter scale 1 earthquake, with about 6200 occurring each year.</b>
<br><b>&nbsp;</b><b></b>
<p><b>A Richter scale 5 earthquake is 10,000 times stronger than a Richter
scale 1 and releases energy equivalent to a small atom bomb (20 kilotons).
Those are damaging quakes, especially if residents and buildings are near
the epicentre. About 800 scale 5 earthquakes occur each year.</b>
<br><b>&nbsp;</b><b></b>
<p><b>A Richter scale 6 earthquake is 10 times more intense than a scale
5 earthquake. It is extremely damaging and the energy released by rock
breakage in equivalent to a 1 megaton hydrogen bomb explosion. About 120
scale 6 earthquakes occur each year. Richter scales 7 and 8 occur sporadically,
are totally devastating and the energy released is equivalent to a full
scale nuclear war of 60,000 one megaton bombs. Australia is a stable plate
with rare low intensity (Richter 3-5) earthquakes. These earthquakes occur
once every few years, in contrast to the world average of 140 earthquakes
a year.</b>

Hello Andrew

No major damage here in Strahan but there where 4 or 5 large trees blown
over on Murchison Hwy to Burnie.
Snow expected down to 600m in the morning giving us a cool 9C max
tomorrow.

Perth recorded a max temp of 21.3C yesterday (Monday), which is now the
12th day in a row over 20C, I believe the record for Perth in June is 13
days in a row. With 22C forecast today (Tuesday), we should tie it. 22C is
also forecast for Wednesday and Thursday, so at this stage, its looking
like a new record for June.

Rainfall has also been well down, only 63.6 mm of rain has been recorded so
far this month, the average is 182.0 mm. It's not record territory, but not
far from it.

Isn't Perth [and the south west generally] starting to show a pretty
substantial negative winter rainfall anomaly over the last couple of
decades?  Might we ascribe this to long term climate change or simply to a
long term natural variation we don't fully understand yet?

Simon, the hourly/half hourly metars Hank refers to are available at
ftp://ftp2.bom.gov.au/anon/gen/fwo/. The files beginning IDY03101 are
packages of METARs and SPECIs for each of the past 24 hours. Files beginning
IDY03001 are packages of the synoptic reports, which are at best 3-hourly,
but carry significantly more information. These files are in comma-delimited
format, making them easy to read into a spreadsheet or to handle with a
program. There is also the bonus of a 24-hour archive, which is not
available, or not easily processable, on the html Bureau products.

Cheers

Laurier

G'day Clive,

This sounds pretty accurate. Tsunamis are extremely long wavelength, long
period waves, most commonly generated by shifts in the ocean floor caused
by earthquakes or lanslides, or erupting volcanoes. Wavelengths can be as
long as 500 km, and periods of tens of minutes, up to 2 hours (compare
average wind generated waves or swells with wavelengths of a few hundred
metres and periods of 10 to 30 seconds).  In the open ocean they behave as
shallow water waves, which means that their speed is approximately given
by c=sqrt{gH}, where G is the acceleration due to gravity and H is the
ocean depth. If you plug in 9.8 for g, and about 6000m for H, you come up
with about 900 km/h - these kinds of speeds have been observed. The
corresponding amplitudes (i.e. heights) are small, no more than a
metre, and they are undetectable visually over open ocean. With such long
wavelengths, energy dissipation is small and so destructive tsunamis can
be generated many thousands of kilometres from their impact area. Those of
shorter wavelength do tend to dissipate more rapidly. The wavelength of
any particular event depends entirely on exactly how it was generated.

Over shallower water, the speed is reduced and amplitude increased. The
form the tsunami waves take when they reach the coast is very dependent of
the local characteristics of the shoreline. Some appear as merely surges
of water (like a fast-forward tide, hence the name tidal wave), some as
bores, and others as breaking waves. Either way, they are associated with
much more energy than wind waves, and so the wave run is generally a lot
longer than a wind wave of comparible height. The 2.5 metre tsunami in
Arica, Chile the other day doesn't sound too bad at first, but this would
produce much more coastal inundation that a 2.5 metre wind wave. A tsunami
moves a lot of water - both in and out. Many victims of tsunamis are
drowned, no surprises there, but they are actually drowned out at sea due
to the retreat of the tsunami carrying them way offshore. One very common
misconception of tsunamis is that they consist of just one wave. In
reality, there is almost always several waves (as I mentioned, they may be
up to an hour or two appart), and the first one is not always the highest.
In between the waves, there is usually a very large flow of seawater away
from the coast. 

All interesting stuff. 

Cheers,

Jonty.

Hello Andrew

Yes, I usually do the weekends and school holidays when the main
observer is away.
I did a two day course to do the synoptic observation, I have to do more
training to
do the Metar obs. Currently here in Strahan we do obs for 9am and 3pm,
there is talk of reintroducing the 4.30am obs for the aviation
forecasters.
When cheap reliable automatic visibility instruments are available I see
no need for observers at places like this. The automatic station only
misses a beat with power failures but this could be overcome.
Cold stream conditions today with heavy rain showers and soft hail.
We drove to Queenstown this afternoon (25km due east) and there is a
thin cover of snow on the peaks above 700m.

The word tsunami translates to "harbour wave". Presumably because the
amplitude of the wave is magnified as it surges into a harbour.

Hi Les.
Looking ok for the UK!,looks like areas to be affected running in line from
east central Wales south-eastward to just south of London, suspect an upper
trough moving slowly from west also some very warm and humid air stagnating
over the central  parts of England, should be primed for locally severe
storms later today look out for some decent overshoots,good luck Clyve
Herbert.

Great post Phil, Ive always wondered about this. In the short time ive been
observing the weather here Ive seen it go from killer summers and winters,
1990, 1996 and 1994 which gave us many storm days and 14 tornades over
summer. Also winter 1996 when Mundaring Weir over flowed for the first time
in 28 years. Just 3 years later it was at 27% full. I also know that the
Harvey area gets about 70% of the rainfall they used to get pre 1950. Barry
from the BOM here told me that the early 80's around 82-84 produced over 30
severe cold fronts and countless tornadoes and numerous heavy rainfall's.
The SW usually averages 4 severe cold fronts a year, normally that is. Now
this summer just gone and winter have given some of the all time records
for lack of rainfall a real nudge. I often wonder if the climate is really
changing or if this is like u said just part of a bigger pattern that we
dont understand. Ive noticed that some of Perths all time low records for
rainfall and hot winters go back to the 1800's. Really accurate weather
data only goes back a short time in regards to what we need in order to see
long time patterns. I guess only time will tell...........

Just to add to this,

I can recall as a kid, winter after winter in the late 60's, significant
flooding of the Canning River in the Thornlie/Gosnells area.  This is
something that has simply not happened in ages, largely due to little
overflow from Canning Dam no doubt.  Of course, that could be explained by
the greater load imposed on the water reserve as Perth has expanded.  But
one thing is for sure, should a really wet winter occur a hell of a lot of
housing now in this area is going to go under water!!!

20 years or even 50 years is way too short a time frame to determine whether
we are seeing normal variation, abnormal variation or trend.  A problem is
that if this is an abnormal trend, it may be masked by the same variation.

Hi all

I found these videos on the Accuweather site a few days ago and i thought
they were worth a mention on the list.  For those who follow US weather they
have several excellent streams for forecasts and current events.  The also
have a great "world report" where they go through the current and forecast
weather for various regions around the world (including Australia)

http://www.accuweather.com/adcbin/video_index

They're great for when you don't have the time to wade through a heap of
sites to find out what's going on around the world

BTW - you don't need cable to view them, the 56k streams are quite good

 In a southerly airstream, I wonder if the west coast of Tasmania is
sheltered from shower activity by the islands mountains. In the South Island
the mountains are aligned SW - NE, thereby blocking moisture in southerly
flows, with the West Coast usually fine in such airstreams. From the look of
Tasmania, it seems the island and its mountain ranges are shaped N - S. Plus
the Tasmanian mountains are a lot lower than the Southern Alps. Is Strahan
sheltered from wet weather in a direct cold southerly outbreak?

 A cold (8C) and wet afternoon in Christchurch; the skifields must now be
getting some decent snow. A really cold southerly southerly blast is
predicted for Friday and Saturday, with snow to very low levels in the South
Island, and possibly the lower North Island as well. (528 thickness line
cuts across central North Island by Saturday in one model) Could be
interesting.

Hi ben, and all.

If your interested in NZ snow chances check out
http://www.snow-forecast.com/nz.html
Click on any of the 10 images (not the three at the top) and at the bottom
of the image that loads there is a temp forecast aswell. Christchurch looks
chilly at around 8 degrees in the next 24 hrs With a freezing level around
1100 metres. Also there is only going to be from 5-25cm of snow in the next
48 hrs on the south island Mountains. Aussie ski bunnies check out
http://www.snow-forecast.com/aus.html although there aint much happening
here..

I did a little bit of work at the Storm Peak Laboratory, at Steamboat
SPrings, Colorado. I guess Storm Peak and Mount Washington are the only two
cloud research labs set ontop of mountains. There seemed to be a little
rivalry between the two, mount washington had t-shirts that said "The Worst
Weather in The World" because of it's harsh climate and strom peak had "The
Best Weather in The World" implying that they got the best clouds to study.
Bit of a geeky joke but amusing anyways ;)

Hi,

i'm bored at work (typical) and was reading the weatherzone forum and noted
that you guys were talking about chasing with computers. Over here, we rely
on calls back to people in the office or local libraries, which are
everywhere, for data updates.

Whats the data access situation like in Australia?

Cheers, Lyle

Hey all,

Hmmmm.  I myself remain convinced that the number and severity of cold
frontal passages in Adelaide has fallen away over the last 10-15 years,
while we now get more rain from east coast lows/troughs and NW cloudbands.
No real evidence, just a feeling.  Once again, i guess this doesn't
necessarily mean global warming or anything, maybe its part of a cycle our
records don't go back far enough to pick up.

p.s. Some WEATHER here would be nice ;)

G'day Les,
Looks like it's our turn here in HK also.
Since Typhoon Chebi passed us by the other day leaving behind 
a "stationery trough of low pressure" we have had thunderstorms several 
times each day and it has hardly stopped raining.
So far this month our rainfall has been more than 1 metre which has 
broken the previous all-time record for June (962.9mm in 1966).
Until midnight last night (27th) the total for the month was 1045.2mm!
The trouble is, I have to keep on working through it all, and don't get 
much chance to get out and enjoy it!
All over the territory the street lights and traffic lights are out and 
there's a lot of minor landslides all helping to make chaos out of the 
traffic (which is usually chaos here anyhow IMHO) and the HKO is saying 
there's a lot more rain to come.
Yesterday afternoon when I got online briefly the HKO had five warnings 
in effect at the same time: The Red Rainstorm Warning, The Thunderstorm 
Warning, The Landslip Warning, The Strong Monsoon Signal, and "The 
Special Announcement About Flooding" (so-named because of a political 
decision announced a few years ago that the Observatory would no longer 
be issuing "Flood Warnings").
For those wanting to do a virtual chase to HK, there are a lot of useful 
links on my http://www.drdisk.com.hk/cyclones.htm page.

Cheers from an extremely wet HK!

Everyone:

Golfball hail and poss tornado damage reported from S. England. Probable MCS
on a CF / squall line moving up from France that did that one. Lightning
reported in excess of several a minute. Anvil crawlers and overshoots
reported from Edinburgh (probably severe pulse). Other severe pulse (sounds
like) reported from Central Scotland with marble hail.

The day it was supposed to happen CAPEs ant LI's  were huge but the cap was
'huger' ):

When it lets go in the UK it can do in style... nothing like the tornadic
cold front in 1988.... yet. However there's still time for that dryline
pushing into a Spanish Plume making it all go off  LP supercell style it'll
probably happen at the Wimbledon Henman - vs - Rudzetski (?) final well you
can but dream (:

Nothing at all here, nor in Central England today. Typical.

Evening all,

Checking the MSL at 4pm
http://www.bom.gov.au/weather/national/charts/synoptic.shtml I find a
high pressure system (H) in the south of the Bight, a low (L) near NZ &
a W......what is a 'W'?

Now, as well as this, what is everything in the Australian area
responding to because the following seem to be happening all at the same
time:
i) unusually active area of convection east of PNG
ii) rapidly increasing levels of moisture & cloud in the Coral Sea
iii) middle level disturbance in Qld expanding southwards
iv) high pressure system suddenly shifted further south
v) low north of NZ

The loop below shows this well

Hi Lyle,

I generally call people for updates, I have a few people I normally get
updates from/give updates to - it tends to be a return the favour thing
(ie, we all help each other out when we can).  So basically it just
depends on where I can get phone reception, and if anyone is available
and near a computer!

Hi all,

Since the weather is a bit quiet on the home front, I have put two of the US 
chase reports up. Without doubt these two quite different events were our 
favourites. Jimmy will be putting his more in-depth reports up at ASW soon 
as well. We both have to grab video stills somtime; we kind of neglected 
photos in favour of video.

Hi all,

Just thought I'd take the opportunity to express my disappointment that
we are a third of the way through winter and so far the SE has had no
more than a third of a cold-snap!

Despite our speculations from a few weeks ago, the sub-tropical ridge
has gone back to being all over the place without us having had the
penetrating low (with a 'W'?) we'd hoped for.

As Lindsay P. has mentioned, the daytime temperatures are unseasonably
warm up here on the tablelands which is disappointing for people like us
who enjoy the hardness of (normal) winters here.

Andrew.

Hi Andrew and all,

Yes, its been a mild winter so far. We've only had a handful of days into
single figures. Monday the 25th apparently saw the max temp just miss a June
record (set in 1999 at 15.8) when the mercury hit an amazing 15.6 at Mount
Boyce AWS. Mind you, the site has only been in service since 1989, I think.

I do think the experience of mild weather this winter has been exacerbated
by the lack of rain (9.5mm for me so far this month) so the sun has been
shining nearly all of the time of  late. We are currently running at more
than 2.5C above average for this time of year, ~12.5C  instead of 9.8C.

I must say, I think my frustration is heightened about it all today because
I can't hear myself  THINK as I sit here and ponder winter or the lack
thereof. There are two massive chainsaws blaring away next door in two part
harmony as well as a gigantic shredder! My house/office is shaking. Time to
go for a walk down the back yard and check things out.

The Brisbane Airport mean for June is currently running at 23.6. This
is 0.5 degrees above the existing record (23.1, 1962), so I'd think
there is a chance of the record being broken, but it is no certainty 
with half the month still to come.

The old Regional Office site had a 23.0 in June 1902. It seems a little
cooler in such months than the airport, so the 1902 obs probably 
equates to something around 23.3-23.6 at the airport. Nothing else
approaches the 1962 mark.

"January 28, 2001:  This chase was a simple case of SDS manifesting
itself physically, making us drive 700+ miles for nothing. Matt, Kelley,
and myself took my car straight down I-35 to San Marcos, TX., where we
stopped at Wendy's, grabbed some lunch, turned around and headed back
home. The Wendy's triple cheeseburger I had was delicious, but not 700
miles delicious."

...it's getting to this stage.......I haven't done a 700km afternoon

Even some clouds would excite things a little, but it has been largely
cloudless here in the Illawarra. Even the strato-cu has deserted. We had a
surprise shower of rain on Monday night, but the rest of the last three
weeks has been dry.

Hi all,

Very cold night on parts of the Southern Tablelands. It's currently
hovering between -6 and -8 here in Taralga and is -6 inside the cab of
my ute which is novel!

It's a good setup for a very cold night - a ridge of high over the top
of us and the high centred just west of here.

Obviously the temp is now very close to the dew point so it's a battle
between fog and rising temperatures, and clear skies and lower
temperatures for the rest of the night. I await the morning's results
with anticipation!

Andrew.

Hell I know how that feels. I have only been out on some 6 chases this year!
If you check my site, I only have one chase to talk about, the other 5 were
either busts or no big storms broke out to make it photo worthy. We went
landspout chasing the other day and ended up in Nebreaska hoping for 3700J
of CAPE to be utalised - nothing went of course but the Wheatland Inn has
some good cheap grub.

Heading out tomorrow to WY/NE - looks like a good chance of supercells, lets
hope ;)

Cheers, Lyle

Hello Ben

Our West coast is aligned NNW-SSE so there should not be any any
sheltering. What I believe happens is the low  has moved to the SE of
Tasmania by the time we get southerly winds and is not producing a lot
of severe weather in that quarter.

Hi all

I'd like to propose we fill a small urn with the ashes of our burnt weather
monitors, to officially commemorate the 'death of winter', this day, the
30th of June 2001.

Maybe the urn could be photographed and placed on the ASWA website to
remind us all of the death of winter, and the extreme SDS [WDS?] being felt
by most of our members...

     Since starting taking rain totals in August 97, June 2001 is now the 
driest month here at 5.8 mm, beating Dec 98 with 15.7mm. High month was 
March 2000, with 283.0 mm.

     When is 'the cloud' coming back from its backpacking trip o/s?

Rune, "the cloud" is right over our place at the moment.  We have had 
more than a metre of rain this month setting a new all-time record, and 
it hasn't stopped raining all night and is still pouring down outside now.

HI.

Very cold night here in Bathurst last night, down to -7.   It tends to help
having heater on before arriving home.

Inside my place was 10 deg..at 10.30pm last night.

We have had severe fogs and frost every morning for last 2 weeks.. Getting
pretty used to seeing white ground
each morning.

      Phil,
        Please stop being hospitable to the cloud. It has been away from 
home far too long and Australia is getting worried for it's welfare, we miss 
it very much.  And tell it no stop-overs in Bangkok this time,..we want it 
functioning properly this spring/summer :)

Great reports and pics David. I got the Rand McNally USA road atlas out and
did a virtual chase with you. It is amazing the action that has centered in
that area ( over the years ) you chased on the 29th.

Whilst running through the atlas you either went through or came close to
several towns that feature in my commercial USA tornado tapes..Pampa,
Childress, Larvene.

'The Cloud'

Rune asked: When is 'the cloud' coming back from its backpacking trip

Phil replied: Rune, "the cloud" is right over our place at the moment.
We have had more than a metre of rain this month setting a new all-time
record, and it hasn't stopped raining all night and is still pouring
down outside now.

I think we need the cloud sooner than that! Just had the driest June here
since 1962 at 3.8mm (2.0 equal with 1953).
The average 9am barometer was 3.0 mb higher than normal.

<DIV></DIV>&gt; 
<DIV></DIV>&gt;Hi all, 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Very cold night on parts of the Southern Tablelands. It's currently 
<DIV></DIV>&gt;hovering between -6 and -8 here in Taralga and is -6 inside the cab of 
<DIV></DIV>&gt;my ute which is novel! 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;It's a good setup for a very cold night - a ridge of high over the top 
<DIV></DIV>&gt;of us and the high centred just west of here. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Obviously the temp is now very close to the dew point so it's a battle 
<DIV></DIV>&gt;between fog and rising temperatures, and clear skies and lower 
<DIV></DIV>&gt;temperatures for the rest of the night. I await the morning's results 
<DIV></DIV>&gt;with anticipation! 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Andrew.

Well, Rune, they have hoisted the Typhoon Signal this morning, so the 
Cloud is likely to get crowded out by hundreds more.  With any luck it'll 
get blown right away from here.
Might head for mainland China first though...

I agree with Michael: the reports are grwat and I wish I still had my old 
Rand McNally...

Michael, your mention of Laverne reminds me of the day we rode a 
motorbike from Shattuck(Sp?) to Laverne through the most incredible storm 
we had ever experienced in our lives to that date.  
We stopped and filled up with petrol at Shattuck and the road ahead 
seemed to disappear into these ominous black clouds reaching right to the 
ground.  The petrol station attendant told us if we headed up that road 
we would be swallowed by a tornado for sure.
All our waterproof wet-weather gear was in the box on the back so we were 
only wearing jeans and shirts.
As we were expected considerably further up the road that evening we 
prayed about it first and felt peaceful about going on.
Before long we had Flang after Flang as the CGs were hitting all around.
We did see swirling clouds touching the ground on either side of us but 
don't know to this day whether they were actually tornados or not.  The 
noise of the thunder and wind deafened the sound of our motorbike's 
engine.
It was rather scary, so we started singing that old Sunday-School 
song: "With Christ in my Vessel I can Smile at the Storm" and just kept 
on riding through.  There was nowhere to take shelter anyway, even if we 
had wanted to.
Several times we saw walls of rain across the road half a mile ahead and 
thought we would get wet for sure.  But each time they opened up and we 
eventually reached Laverne with not even a spot of rain on our bike's 
windsceen although our boots were wet from the several times where we had 
ridden through water covering the road after what had obviously been very 
copious downpours.
We stopped for petrol again at Laverne and the attendant asked us where 
we had come from and we said "Shattuck".  He said "Impossible, the road's 
closed by floods." and pointed.
We looked around and 200 yards behind the motorbike the police had pulled 
two cars across the road to prevent any traffic from proceeding.  And 
less than half a mile away, there was just a solid wall of falling rain 
that covered the road and both sides of it.
It was kind of humbling; we wondered what Moses had felt like after going 
through the Red Sea.
We saw a great number of other magnificent storms that day, but they were 
all at  a safe distance.  That one was the only one we went right through 
the middle of.
This was in July 1978, but I have forgotten the exact date and left the 
diary for that year in Australia years ago.  I wrote up a very full 
report of the storm in that diary, too.  Wish I still had it now.

Hi List,

A little while ago someone was after cups for an ana thingy for measuring
wind speed, and was considering constructing same (ping pong balls were
mentioned).

Weeeelllllll - Cleaning up about the place earlier, I came across an empty
50ml Rexona personal deodorant container. The plastic lid of same would be
perfect, maybe with some minor modifications. Different colors available!

Might help ?!!!!!!!

To get to weather - 8/8 cloud cover, 25-30 knot SEasterly, showers off the
coast, but currently fine here in Proserpine, 2mm to 6am, temp now 19.5°C,
barometer on 1020.

Seems all are enjoying the high pressure systems?

Regards,
Bill

Where are you? I'm down 21mm for this month and 78 for the year to date.
Interestingly, February is the only month I had that went over the average
by 27mm.

Andrew and Lindsay,

Don't despair as the probability is that when it does come it will come in 
full force. I am actually quite excited that it is lagging as you may find 
that July may hit us hard. Well we shall see. And of course if I am proven 
wrong, then October late season is something to look forward to. Weather 
has its way of balancing itself but we find it when don't know which way.

Don't get me wrong. I am also disappointed with lack of action too but I 
suppose over the years I have learned to pass the time so to speak. I also 
advise not to look too far into models or at least get overexcited over 
them when they look fantastic. This is why I like AVN as it only goes 3 
days out.

Anyway enough from me.

Thanks for the suggestion. But now I have decided to manufacture the things
myself. I have designed a jig for bending hot acryilic plastic to the right
shape, so I will make my whole weather station instruments from acrylic
plastic. It will look really good to, and maybe oneday I could even retail
it in kit form..... :-) Thanks

Hi all weather starved cloud watchers.
Interesting to see what appears to be a mid level disturbance over central
Vic this evening,there are two decks of AC with the lower deck at about
10.000 moving from the south and an upper deck of AC around 13.000 moving
from the north, although non active its worth watching this upper system
over the next 12 hours.regards Clyve Herbert.

I think we need the cloud sooner than that! Just had the driest June here
since 1962 at 3.8mm (2.0 equal with 1953).
The average 9am barometer was 3.0 mb higher than normal.
