The photo of the rotating mesocyclone was rejected by The Geelong News,
Victoria, Australia.....because there were no people standing in the
pic!!!!. The photographer, a well known Storm Chaser had 'evacuated the
area' before 4cm hail started falling & became concerned when suction
vortices started spinning up in the paddock. The storm later went on to
devastate Corio with up to 50mm falling in less than 30 minutes.
Therefore, the trick is obviously make sure you have the townspeople with
you when you take photos of funnels & cyclonic rotations to give the picture
a 'human interest' angle.

I have 2 Sydney March ASWA venue options to suggest;
1) My house at Lindfield on Saturday 13/03/99 from 10am. This option
will allow my wife to use our car instead, view videos OK and to
provide some distractions to my elder sons aged 3Y6M and 5Y9M.
Normally, they'll play at a friend's house nearby until lunchtime.
2) 7/255 Elizabeth Street in the city same time Saturday. This venue
has secured access for which I would need your names to give to the
security officer to allow entry.
Please sort this out ASAP as I am unable to attend the March ASWA
meeting if it takes place after this coming weekend and I would
also miss the NSW April ASWA meeting as well due to my travelling
to Kangaroo Island (SA) and Victoria. I might be able to attend
the Victorian April ASWA meeting if Jane can let me know where
& when.

That's ludicrous!!! What are you going to do? Say "excuse me, could
you please stand in front of that tornado coming towards us, so the
media will use my pic? Don't mind the near tennis-ball size hail, and
flying debris, it won't hurt too much."
Australian media...I could say some words about it, but wouldn't be
appropriate for this list :)
On the other hand....I'll give $5 to whoever scans that pic first!!!
(Ok, I won't...but please scan it soon, I'm already dying to see it!)
Again...it's a total joke (the media)

This is from my previous post of 25th Feb:-
*************************************************************
I just wanted to take the opportunity to remind ebbywun not to miss Channel 7 on Saturday night, for Frank Warrick's World Around Us
It is a tornado special feature -about (but, I stand to be corrected) - but I think, about the terrible outbreak in Texas, USA on May 27th, 1997 - that resulted in an F5 wiping out the Double Creek Estate of Jarrel. 27 people were lost ... the devestation was complete and unprecedented...
.. a couple of sites to bulk up on before the night:-
http://www.met.tamu.edu/research/texacal/outbreak.html
http://weather.cod.edu/notes/jerrel.html
http://www.tornadoproject.com/index.html
http://www.pulse.net/storm/jarrell.htm .... (not for the faint-hearted ok!)
Sure to open your eyes
************************************************************
It was the Jarrell tornado, the footage was arresting to say the least.
Yes, I have successfully taped the show, if anyone would like copies but email me direct and we'll arrange.
rals!!!

Just a reminder and to the new people on the list, that our weekly IRC
meeting on Austnet's #weather is tonight.
server: au.austnet.org
on the #weather channel.
Meeting starts at 9pm EDT, 8:30pm CDT, 8pm EST, 7:30pm CST and 6pm WST.
To the newcomers on the list, if you havent used IRC before, you can
download the best IRC Client http://www.mirc.co.uk/ use one of the austnet
servers, then type /join #weather
The channel is open 24 hours a day, but most of us visit on Wednesday night
for the weekly meetings.
Also, to the Adelaide people, we've never seen any of you on the IRC chat
channel for a long time (if ever?), we've got all the other 4 major cities
represented though, where are you all?:)

Paul,
If you were coming by a bus as you did another time before, you
could ask the driver to stop just 350m past Lindfield from the
Pacific Hwy one street south from Grosvenor Rd (where lights are).
There is Eton Road heading off the Pacific Highway heading SSW
where you'll find my house, No. 47 on the right about 400m from
the highway - easy. Better still, just look my name up in;
http://www.whitepages.com.au/search.shtml
and a nice map will be displayed.

Hi everyone. Just had a look at the AVN,MRF,Tot-Tots and 200mb winds for
Friday and Saturday in Victoria and things are looking exceptionally
good.
The LI's are around -2 to -4, the tot-tots are around 45-50 on Friday
and 50-55 on Saturday and the jet stream picks up a bit of strength on
Saturday too (assuming I've read the thing correctly ).
I can't chase on Saturday due to playing in a cricket grand final but
I'm up for a chase on Friday if the charts don't change too much. Any
Melbournians intersted?

Hi Paul,
Sorry this is so late in reply...
SFERICS was used in the 70's by a number of researchers to detect
tornadoes...but the way I heard it was they used TV!! They tuned to a
certain channel (the exact one escapes me) and dialled the brightness
down until you just couldn't see it...then they changed (up or down?) a
few channels and if the screen started glowing brighter and darker it
meant a severe storm was coming.
It must have had something to do with the band of EM radiation produced
in severe storms...sorry I can't help with specifics...I'm going from
(long-time ago!) memory :)

The first I read about the Jarrell Texas storm was in an issue of the Storm

scan the issue because of copyright limitations.
So check the article on the Storm Track home page from our links site as
Michael suggested.

Hey Rals
This is the info i have on The Total-Totals index from my Soundings
page, it's pretty much self explanatory:
Total Totals: The Total Totals field show instability in the atmosphere
based on the lapse rate from 850 - 500mb plus Dewpoint at 850mb. It
consists of two components, the Vertical Totals (VT) and the Cross
Totals (CT). The VT represents static stability or the lapse rate
between 850 and 500 mb. The CT includes the 850 mb dewpoint.
A Vertical Totals (VT) of 40 is close to dry adiabatic for the 850-500
mb layer. However, VT generally will be much less, with values around 26
or more representing sufficient static instability (without regard to
moisture) for thunderstorm occurrence. A Cross Totals (CT) of 18 or
more is often necessary for convection, but it is the combined Total
Totals Index that is most important. Like the K Index, larger numbers
correspond to a greater likelihood of thunderstorms. Threshold values
vary from place to place.
44 Isolated to few Thunderstorms
46 Scattered Thunderstorms, a few may be moderate
48 Scattered Thunderstorms, a few may be moderate and
isolated severe Thunderstorms
50 Scattered Thunderstorms, a few may be severe and isolated
Tornadoes
52 - 58 Scattered to numerous moderate Thunderstorms. Scattered
Thunderstorms and a few Tornadoes.
60 Numerous moderate thunderstorms and scattered severe
Thunderstorms and
Tornadoes.
You can get the Total-Totals charts from the MRF model at
http://grads.iges.org/pix/aus.fcst.html
I may be stepping out on a limb here, but IMO they don't really do much
for us up here.. more so for the southern states, but then again i'm i
don't really follow them religiously so i could be wrong.

Hi everyone,
I was wondering if someone on the list may be able to answer
a question that has had me puzzled for years now. Why are good active
warm fronts so rare in the southern hemisphere? I have asked
professional meteorologists this question and have received different
answers, ranging from 'I don't really know why'; or to the absence of
substantial polar continental air masses; or the fact that circulations
in the southern hemisphere are strongly zonal in mid latitudes. We are
familiar with a process known as 'upslide' which results in a similar
sequence of weather and precipitation as a warm front; however without
the temperature discontinuities at the surface.
Also, without warm fronts we hardly ever get to experience the classic
occluding cyclones so prevalent in the northern hemisphere.

one absolutely magic shot of mammatus, clear air & a flanking line!!!!! and
another 180degrees shot from the west of the line that advanced on Mt

I'm surprised Ben hasn't said anything yet :) But as you all may

Hi all,
Rals...you may be more familar with the term "TT's" over "tot-tot's" I
know I use TT's more...
On the subject of TT's, I have to agree 100% here...I never take TT's
very seriously unless they are over 50-55, then I use it as a
guide...but there's been many times that TT's have been high in Brisbane
(and many other places for that matter) and nothing has happened. Then
again, there are very few variables that can be used on their own to
forecast severe weather. I always look at the following variables when
looking for t'storms to develop in SE QLD:
N'ly winds
LI's below -2
Surface Trough
Upper level trough
Jetstream strength
VV's
Upper level temps (to have an idea on possible caps)
TT's as a guide
There are many other small 'things' I look at too, but I guess it comes
down to personal choice. But those are the main variables that I look
for, for t'storms in SE QLD.
Another important note is the personal 'caliberation and adjustment' of
the models to your district. For example, I've often found that the
models underestimate our jetstream in SE QLD. I've also found that they
over-estimate a lot of TT and LI values...as well as a host of minor
alterations that I make personally. I'm saying this because a lot of
people often get excited when they see a forecast of low LI's but then
are not as low as forecasted.

I have to say that from a Sydney perspective I agree (not that there
been much of an opportunity to really test it this year!). I know that
the TT threshold values on storm likelihood are standardised for the
US midwest; they do not hold on the high plains over there and,
although we can't use altitude as an excuse, they don't seem to hold
here either for some reason (both the forecast model and sounding
data). Also, the model output is a bit old hat by the time we get it.
The AVN model runs are updated more frequently and the LI seems a lot
better predictor of storms. One thing I have noticed is that on many
occasions, a day or two out, the LI almost invariably underestimates
the northward movement of trough/frontal systems so that activity we
expected in the Sydney area (based on the model) gets shifted north
when the day arrives - maybe this somehow stems from the aberrant
weather patterns which have resulted in us having an unusually low
number of storms this season, and places like the Riverina area in
southern inland NSW having a greater than usual number of storms.

The main reason we've been excited down here when we see the models is
that they have tended to be very accurate for Victoria this
spring/summer. This weekend is looking good as all models are pointing
towards a very active weekend although against that the bureau are only
forecasting showers/rain.
There should be a lot more photos to go with the MSC reports in the next
week or so.

David,
This is what happened last Sunday with the Quirindi Hunter chase.
Everything raced northwards.

My answer will be probably rather layman, but in my understanding it is
simply the lack of continental landmass in the higher latitudes, say over
45'S. You will sometimes see warm fronts over the southern ocean.

That is exactly the scenario last weekend, Friday night AVN had Sunday LI's
going ballistic in the Blue Mountains area, come the Saturday night run and
the LI's had been scaled down and moved further north to the Hunter Valley,
come the Sunday and we found that the real situation probably had LI peaks
over the Northern Tablelands.
Speaking of models there is a wide variation in just what they are saying
for the weekend. The NGP is looking good, going for a nice deep trough and
widespread storms over the southern half of NSW, the Bureau GASP has a
similar scenario.
AVN and COLA MRF are going for little action from the trough, although AVN
clearly has the same deep trough it suggests little precip from it, MRF
backs this up.
The trough looks to good, it would be hard to imagine that it could not
produce some action.
