Hi all, 

The Oberon snow pics are in and they are good! Remember, this is snow
from the Central Tablelands west of Sydney. Looks a bit like the Snowies
don't you think? And it was thicker than this on day two and three of
the falls too!

Michael Bath has kindly set up a page showing a few of the shots.

Thanks Michael, I appreciate your efforts.

Check them out on:

Hope I got that address right.

Cheers,


Lindsay Pearce

Hi All

Just to introduce myself to the list.

I am the Fire Control Officer / Emergency Services
Coordinator for the Warringah and Pittwater local government
areas.(Sydney)

I have been in the Rural Fire Service for 19 years. 

My interest in severe weather is obviously based on the
Emergency Response to the after effects but I have a
personal interest in the formation and composition of
developing storms.

I have at my Control Centre a local weather station
(Innovative Research -Environet) which also transmits and
receives other areas.

I would also like to hear some comment on the Lightning
Strike programs that are currently available as to their
suitability for use in Emergency Management.


ps.Jimmy, I have many more pics of the Hailstorm and also a
aerial video surveying the damage if you are interested, I will
burn a CD and copy the video just let me know where to
send them. 


Regards

Craig Geddes

Michael,

I've corresponded with the lady on this subject before. I think her
need to know stems from research she's doing into some type of wattle
distribution. I've since deleted my response at the time (it was over
a year ago), but recall giving some general information about the way
in which the Bureau's rainfall/climatic district boundaries were drawn
up, based on watersheds, rivers, even shire boundaries. In particular,
I emphasised that, although the Bureau's climatic boundaries are lines
on maps, real climatic boundaries are much more diffuse. 

I remember telling her that the name "Central" was because they were
between the Northern and Southern, but don't remember being asked
approximate area -- and I don't know the answer, but if she has a map
she can surely work that out.

Why is this particular area called the central tablelands?  You have drawn a map of the approx. area on your internet site so I'm guessing you have some idea of it's boundaries and what area it covers because nobody else I've tried calling seems to have any idea.  I would really appreciate any information you might be able to give about this.

It gets better all the time! I reckon, and this is only a
guess, that man-made-snow-making in Perisher Valley given 
particular wind directions will also put "snow" into their
snow-rain guage as well...Check it out if you like. The
guage is about 20m from the beginners J-Bar where the first
line of snow guns are. The "snow" plume from the guns 
sometimes floats right over the weather station! This last
week, I noted that Charlottes Pass recorded 0.6mm one night
and Perisher 10mm. Historically, Charlottes Pass gets that
fraction more snow than Perisher and this anomaly was
recorded after a night with strong W-SW winds while the 
snow guns blasted away all night at Perisher.

Yo Anthony,

What are those strange white scrapes across the Northern sky & those wierd 
cauliflower things off the coast?  Are they what people call "clouds"?? 
  (Quick quick Anthony, grab the camera - you may be able to get one of 
those elusive "winter cloud" photo's....)

Seriously, this is the first bit of cloud of any sort that I have observed 
for 9 straight days, 12 if you don't count a 1/8 cirrus day.

Coldest morning so far this winter at Mt. Crosby - a calm chilly 4.0C, 
still no frost observed, though it felt like it.  Will be interesting to 
see what Ch 9 reports Ipswich as.  Saturday morning they reported Ipswich 
as -2, yet I recorded a +7.5 (I am in Ipswich shire).  Something bizarre is 
going on here...  Does anyone know where Ch 9 gets the Ipswich figure, I 
bet it is actually Amberley's, which is another 10k's or so to the 
SouthWest.

John.

It is almost certainly Amberley.

As I've mentioned before, topography can make a HUGE difference to
minimum temperature under clear skies - a 5-degree difference between
a hilltop and valley site is commonplace. As an extreme case, there
is an instance in the NSW Snowy Mountains when Cabramurra (on a steep
west-facing slope) recorded a minimum of 0 degrees; Kiandra, in a 
valley 15km away and at a marginally lower altitude got -18! Although
I haven't checked the actual numbers, I expect that there would have
been comparable differences between Crackenback and Charlottes Pass
when Charlottes got its -23. As another example, on one of the frosty
mornings in late April in Victoria, Mt. Dandenong was the warmest 
place in the state!

(Also, in the current spell in the NSW Northern Tablelands, compare
Guyra with Armidale and Glen Innes)

Aside from the thread of severe weather on Lake Burley Griffin,
sorry for this diversion...Given the distinct lack of "fair-play"
political decisions in recent time, perhaps it's time to shout 
them (some politicians) a pleasure cruise:-) 

That comment's enough to get aussie-weather at world.std.com

For my recommendation, you may need access to an ANSI 
C-compiler for the operating system of your choice if
pre-built binaries are not freely availble. Check first! 

The fastest gif animator I have found is;

http://www.danbbs.dk/~dino/whirlgif/

Binaries for Windows  are available for 
whirlgif but I havn't used them. The version that I have
operating under Solaris 2.5.1 is blindingly fast by 
typically animating 150 x 78KB global satpic gif images
to a single 11.7MB animated gif file in 15 seconds.

The most flexible and capable of exploding animated gifs
into their individual images can be found at;

http://www.lcdf.org/gifsicle/

This is targeted toward the UNIX/Linux community which
would require some source code / make file hacking to
get it to build under Windows . From what I
can tell. Following the links from here might reveal 
someone who has done just that.

I suggest that you consult the READY site;

http://www.arl.noaa.gov/ready/cmet.html

In that, you'll find roll-your-own metrograms from which you
can select "Geopotential Height (3D)" at a given pressure, say
850mb, at a given location. This is the height, in decimetres, 
of the 850mb pressure. Don't confuse "Geopotential Height" with
"Thickness" since the former is the height given to the mean 
sea level and the latter is the height between selected pressure
levels, say 500mb to 1000mb. As an example, the 1000mb pressure
level can be sometimes below the mean sea level, during a "low",
for example, or above it, mostly.

Now if the BoM offered the equivalent of READY. I'd use that
instead (hint, hint).

Hi Blair,

Thanks for this, I keep thinking either my thermometer(s) are having me on, 
or Ch 9 is.  I am located in the foot hills of the Southern extremity of 
the D'Aguilar range, about 13ks directly due North of Ipswich.  My actual 
elevation is not that high, maybe 70m above sea level, but I am on a ridge 
with a gully 11m deep on one side and sloping down 15m along a 100m 
driveway to the road on the other.  It is an acreage property in an open 
forest location, with a clear grassed area next to the house on the ridge 
top.

Amberley is actually more like 15k's SW of Ipswich, and someone told me 
recently that the temp there is actually recorded on the tarmac at ground 
level (probably not true).  Certainly it is very flat and open compared 
even with Ipswich itself, thus I would suspect that Ch 9 is doing the 
Ipswich population a real disservice it is using Amberley's figures.

>snip

It is almost certainly Amberley.

As I've mentioned before, topography can make a HUGE difference to
minimum temperature under clear skies - a 5-degree difference between
a hilltop and valley site is commonplace. As an extreme case, there
is an instance in the NSW Snowy Mountains when Cabramurra (on a steep
west-facing slope) recorded a minimum of 0 degrees; Kiandra, in a
valley 15km away and at a marginally lower altitude got -18! Although
I haven't checked the actual numbers, I expect that there would have
been comparable differences between Crackenback and Charlottes Pass
when Charlottes got its -23. As another example, on one of the frosty
mornings in late April in Victoria, Mt. Dandenong was the warmest
place in the state!

(Also, in the current spell in the NSW Northern Tablelands, compare
Guyra with Armidale and Glen Innes)

Hi Peter,

Unfortunately, there is no basic conversion from 500mb to 5700m....they
vary from time to time.  IE, the 500mb level in Tasmania could be 5300m
high, but the 500mb level in Darwin could be 5750m high.  This is
because cold air is denser then warmer air, this means it takes up less
space, which is why the 500mb height in colder air decreases.  Where as,
warmer air takes up more space, and consequently the height of 500mb in
warm air is higher.  If you look at soundings:
http://www-das.uwyo.edu/upperair/au.html
you can get the current height, some models can also give you an
indication (ie 500mb geopotential height, is the height of the 500mb
level in metres) unfortunately
http://www.arl.noaa.gov/ready-bin/arlplot1.pl?metdata=AVN+191+km is down
at the moment, so you can't get that info from there (it's the easiest
format)

But you can go here: http://sgi62.wwb.noaa.gov:8080/cgi-bin/disp_avn.sh
and choose: "HGT" and select "500mb" at the bottom, and choose
"australia" as the location, and then also input your times, and that
will give you heights.

But again - there's no direct conversion.

Hope this helps, if you want more info or clarrification, don't hesitate
to email me personaly.

I recorded 8.7C this morning, but after taping the thermo sensor to the
roof a few days ago, yesterday morning it fell off (and for those of you
who have seen my room, you know that I have two thermo wires going
across my bed to the window) and a large coil on the shelf beside my
bed...well, when it fell off (around 6:30 yesterday morning) I had about
8m of coiled thermo wire fall on my head :-(  It was certainly a rude
awakening.  I will need to invest in stronger sticky tape   I would
like to make a small stevenson screen in the back yard, but the
clothesline is just outside my window....my parents bedroom is in a
perfect position for a stevenson screen just outside, I wonder if
they'll swap :-)

I'll buy some brackets over the holidays and nail it up on the roof
eave...I'll also buy a plank of wood so that the sensor doesn't get hit
in the early morning/late afternoon sun.  I hope the ladder holds me :)

Back to serious stuff...

Will be interesting to

One could debate why you watch channel 9 news :-)  I watch 7/10 for a wx
report (if I do watch them, as normally I make my own forecasts). 
Although none of them are really outstanding (Ray is no where as good as
he used to be).  I think the Ipswich temperature is Amberly, but don't
quote me on that.  But I think the position you live in, has a great
affect on your temperature reads.  Especially near a forest/near the
house etc.  I'd consider trying to set something up away from the house
and in an open area (if possible).  If not possible, some trees may need
to be sacrificed! :)  As Laurier pointed out too...topography does play
a very large part in temperature recordings.

Wow, Lindsay, you *really* did go snow chasing!  Like that lady in
Twister said "when you said you went storm chasing, I thought it was
some kind of metephor or something."  Replace "storm" with "snow."  None
the less, some quite impressive pictures from the area I thought.  But,
you didn't even have gloves on in the snow!?!?  (commence) Brisbanite
whinge)  The other night, when I was talking to MB on ICQ, he was
laughing at me because I was wearing gloves while typing, from memory it
was 8.4C I think (?) And my hands were still frozen! (conclude
Brisbanite whinge).

Back to the study books for me!

There are two roads south-east of Canberra which get up into the 1200-
1300 metre range; the Braidwood-Cooma route (via Numeralla) and the
Captains Flat-Jerangle-Bredbo road. Both are decently maintained
gravel but in fairly remote country and see very little traffic (in
other words, if you got into trouble in the snow it's likely to be a
while before help turns up), especially the Numeralla road.

The highest peaks in this region are Tinderry Peak (about 1600) and
Mt Tumanang (sp?) (about 1480). There is a fire trail which gets near
the top of Tumanang, but I don't know if it's driveable/open to the
public. Tinderry is only accessible by foot.

A few (weakish) Cb cells are evident to the west (along with a fairly thick As
cover). Radar showing
a few showers associated with this so will be interesting to see what happens.

A pretty warm 13 degrees at 2.30pm.

To Matt Smith - the best thing to do when you are in Ulladulla is to contact one
of us Canberrans.
We can then tell you whether there is snow close to Canberra or if you have to
go further south
to the Snowy Mtns. We can normally see snow on the Brindabellas from Canberra if
there
is any on the ranges.

Currently there are some patches of snow visible on Mt Ginnini (about 1700m) - a
big reduction
on the sea of white that was visible last week. Friday's warm temps and rain
removed most
of that cover.

What we really need is a web cam on Mt Ainslie - it would be good for snow
viewing at this
time of year and for storms during the warmer months.

Hi all,

Ok now who is sitting on their winter cloud photos?

We have not had many entrants to July's theme.

So far only 2 people have submitted photos. :(

So the purpose of this email is to remind that submissions
for July's competition are closing at 12 midnight, Sydney
time, between the 26-27th of June.

The theme is "winter cloud photos" and anyone can submit
photos as long as they are taken in Australia or its
territories and follow the theme.

This means that you do not have to be a member of the
Australian Severe Weather Association to submit a photo, nor
do you have to be a member to vote on the current months
photos which are up for display.

Any submissions of photos need to be either 400 pixels in
width or larger (larger ones will be scaled back)

Please indicate the place and approximate time these photos
were taken and also your name :)

Submissions can be emailed to me at

webmaster at severeweather.asn.au

Thanking you in advance for your submissions.

Thanks Laurier and Andrew

I stayed away from the BOM boundary as  tried to be more "climatic" I did
not include the reference to the BOM map, so thanks Andrew. Have quoted my
answer below ,  welcome any criticism as I do not live in the area.

"You may find the boundaries are defined by parish, but this is not always a
geographically accurate measurement. My boundaries are just that, my
interpretations.

The northern one is easy as the Hunter / Goulburn Rivers almost slice the
Great Divide in two, so the north maximum of the Central Tablelands is
defined by the upper hunter valley, towns like Merriwa, Cassilis, Mudgee.
The western boundary can be the Macquarie river in the north, but then
heading southwards towards Orange away from the Macquarie, as the Macquarie
swings back SE and onto the tableland proper.. The south is a bit tricky, as
you probably already know coming from Canowindra that it slopes away towards
the SW quite dramatically, at what point on this slope away do you say no
longer tablelands ? definitely Cowra. Southwards I would extend the central
tablelands across the north ridge of the Lachlan / Abercrombie Valleys,
anything further south like Crookwell I would be tempted to call southern
tablelands. East is also tricky, you will find that many will include the
blue mountains.

I will forward your message to the Australian Weather newsgroup, we have
several members from that area, Blackheath, Orange and Katoomba. They may
know the ' official ' boundaries."

Michael





I've corresponded with the lady on this subject before. I think her
need to know stems from research she's doing into some type of wattle
distribution. I've since deleted my response at the time (it was over
a year ago), but recall giving some general information about the way
in which the Bureau's rainfall/climatic district boundaries were drawn
up, based on watersheds, rivers, even shire boundaries. In particular,
I emphasised that, although the Bureau's climatic boundaries are lines
on maps, real climatic boundaries are much more diffuse.

I remember telling her that the name "Central" was because they were
between the Northern and Southern, but don't remember being asked
approximate area -- and I don't know the answer, but if she has a map
she can surely work that out.

for the Central tablelands area.  For example what are its boundaries? What
approx. area does it cover?  Why is this particular area called the central
tablelands?  You have drawn a map of the approx. area on your internet site
so I'm guessing you have some idea of it's boundaries and what area it
covers because nobody else I've tried calling seems to have any idea.  I
would really appreciate any information you might be able to give about
this.

What a good thing it is to be able to communicate things on the list.. The
following photos were taken on the 1st May 1994. Now as some people know, I
write down observatiuons every day and attach the closest of all the photos
that match the conditions that day   forget about this octas stuff..

01jd01.jpg    02   and  03

Michael Bath also took photos from his place almost at the same time and it
wasn't planned either!!!!

01mb01.jpg  and 02 as well

Well, these were the type of conditions we had today  almost a repeat
forget the lack of storms we had on that day  It was a heavy downpour with
lightning and the storm then moved on east.  This is a typical cold upper
air situation or cold pool of air as some may know it. We must watch the
nest few days unfold.

Excellent photos Lindsay, next fall I am going in by Wombeyan Caves, I know
the road is bad, but I do have a 4WD Nissan Patrol and to Shooters Hill from
Shellharbour it has to quicker via this route , then the more traditional
across the Blue Mountains.
