I am not saying that this particular storm was a supercell, but I do want
to mention a word of caution when considering the visual (or often even the
radar appearance) of storms.  As we all know, supercells are often
accompanied by a trailing flanking line of convective towers along the
outflow boundary.  These same cells or congestus towers will normally
overtake and merge with the storms updraft region and often lose their
individual identity.  However, not uncommonly, these cells will not lose
their identity but will travel through the storm complex, often along the
rear echo flank.  But at other times, these or other flanking cells will
grow explosively and merge with the storm , playing a vital role in
production of additional mesocyclone cores and severe weather.  Thus, both
on radar and visually the storm will exhibit both multicell and supercell
traits simultaneously.

Many have written on this process, including myself.  For the first time
and in my first publication, I wrote on this process in 1970.  I have
written on it again since.

Many of our concepts of steadiness and the 'single' cell nature of the
supercell were developed when radar resolution was relatively poor and the
visual storm appearance had little to do with storm research.  Moreover,
many neglected the statements that the supercell was relatively steady and
single cellular for the periods of time required for a parcel of air to
pass into and through the storm.  That did (and does) not mean that it
remained that way for much longer time spans.  Note that researchers at the
National Center for Atmospheric Research (NCAR) in Boulder, CO during the
early 1980's even suggested a 'new' storm type called the "West Plains"
storm, which was more weakly multicellular and evolutionary than the
multicell storm but more unsteady and multicellular than our concept of the
supercell at that time.  Now the primary storm classification system
includes only the "ordinary" and the "supercell" storm.  Both may be
multicellular (and probably are).  However, the secondary classification
scheme with includes the single cell, the multicellular cluster storm, the
supercell, and the multicellular line storm is still used as well.  Many,
including myself, doubt the existence of truly single cell storms.  As our
instrumentation resolution improves and our visual understanding improves
as well, the multicellular nature of all convection is becoming more widely
accepted.

Hi everyone,
	I have put an enhanced NOAA 12 VIS image of the Evans Head storm
at: http://marconi.mpce.mq.edu.au/~paul/interesting/EvansHead.jpg
	The image is from 1731 EDT, 31-12-99 ( I suppose that would be
0631Z)
	I suspect the Evans Head cell is the N most cell on the picture.
Cheers,
	Paul.

There is apparently nothing wrong with the Atlantic circulation, please
take this warning  in the same vein as Nostrodamus, the Millenium Bug,
the end of the world, flying white horses, etc.

So no need to get that really BIG boat built yet!

However, there is the North Wall effect which you Ozzies might find
fascinating reading (in times of SDS ) at the USN Norfolk website:

Look for OTSR/MET/PUBS on the left (thats where it is in Netscape) then

Hi all

Paul in Darwin noted large hail was reported near Armidale yesterday.  All I
heard was that the New England Highway in the vicinity was closed due to the
large amount of hail causing cars to skid off the road.  I heard that on the
midnight news, but other than that I have no info.

A severe thunderstorm (among many) also occurred at Bundaberg, as reported
on the ABC site:

Bundaberg awaits repairs after storm
Emergency workers say it could be another two days before repair work can
begin on two Bundaberg homes damaged by a viscous storm last night.

Producing lightning, strong winds and hail the size of golf balls, the storm
lifted part a roof off a house and an attached garage.

The storm cell was among several that at one stage stretched from Gladstone
to the New South Wales border.

State Emergency Service local controller Beverly Thompson says the affected
properties have been temporarily secured.

"Probably because of the holiday it will be fairly difficult to get a
builder in," she said.

"It will probably be Tuesday before those jobs [are attended to].

"We've tarped [tarpaulined] the house and made sure it's very secure and the
builders will come in and probably have a look at it but it will probably be
Tuesday before they get access to building equipment."

There should be storms inland of us (Brisbane) today; already there are
storms developing in the Bundaberg region (Wide Bay & Burnett) as I type
this.  Hopefully nothing serious will happen up that way.

Regards

In Melbourne it was exceedingly hot - one of only 5 instances of three
or more consecutive days over 40. (Nhill reached 46 on New Year's Eve).

Definitely no repetition this year! (unless you're in WA)

It's probably an observation in the sun (readings in the sun were 
taken routinely at that time). The screen temperatures were hot enough,
though - 41.8 on 31 December, 43.1 on 1 January, 42.1 on 2 January
(and the first two nights of the 1900s were both over 30). These are
Stevenson screen obs - I don't know what the Glaisher stand readings
were. (Adelaide kept dual records for ~60 years, and the 47.6 is a
Glaisher stand reading - the Stevenson screen that day recorded 46.1,
which will make for no end of confusion the day that Adelaide has
a maximum between 46.1 and 47.6!).

Sometimes storm systems can look great on radar, and hint a possible supercell characteristics, but plainly not be a supercell to the spotter observing. Of course it works on the flip side. Some storms can look like nothing sometimes yet hold features that the radar hasn't or can't pick up.

I firstly stopped about 12 Km North of Pt Wakefield to watch a farmer harvesting his crop and putting up heaps of dust, some of these started to spin, but due to lack of heat on the ground I don't think they got enough momentum up to keep rotating. From there I headed out towards Snowtown, my original idea for going up that far was to see how they were progressing after the 8/12/99 Supercell, which went through the area, still quite a few trees still laying over and sheds still partly demolished. Anyhow, I did not observe to many DDs (Dust-Devils) there so I decided to keep going a little further, 20km's later I spotted about 3 to the side of the road, I left the main road on the first available side road and headed towards the DDs. They seemed to be coming off one paddock so I headed straight for it, then the road went away from it (typical) I managed to find another road that put me right in the path of them, but they died out when I started shooting :( From there I followed the road around and saw a few more smaller DDs but there were twice the number feeding off one paddock, I decided to stop the car and take some shots, a huge DD went across the road I took a few pics of it. I headed towards the paddock which it came from and waited, nothing hmmmm, I turned the car around then went up the road a bit, then turned around again and came back to the original spot, BINGO about 4 or 5 DDs to begin with, all very small but boy they were fast. I jumped out of the car with camera in hand to photograph them, but when I got near them they died (do you think by now I was getting peed off). It was only a matter of time I saw approx 60 in a 2 hour period, not a bad effort, I did manage to chase one on foot and get close enough to get some close up pictures, I also tried my luck at core punching on, it was relatively small, but the wind was pretty strong, took all my energy just to get to the thing. one I managed to get inside it was cold, far from what I had expected, with me jumping inside and disturbing the airflow, it collapsed, but regained strength as it reached another paddock. Over all I think it was a great success I will be planning on going out that way again on Thursday or Friday, so if any SA chasers want to tag along please let me know, I think it would be more fun with more ppl and double the amount of camera equipment. I have tagged this area "Dust-Devil Alley" :) Loved every minute of it, in some way, I hate to say it, but it was more fun than chasing a storm. Only because there were more of them and they are fast. I wonder what a huge DD doing 300K's would be like :) regards Andrew Wall State representative for S.A. and N.T.

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi everyone, This is all I could find on yesterday's Armidale hailstorm (from the ABC News site). I also recall the Bureau reporting "Severe hail" which I think means >5cm. *************************************************************************** Armidale cleans up after storm ARMIDALE: The clean up is continuing in Armidale in New South Wales's north following a freak hail storm. About 50 homes and other buildings have been damaged in the storm which struck around 6:00pm yesterday. Neville Clarke, from the Namoi Division of the State Emergency Service, says his officers have been kept busy overnight. "Some of those jobs would only be water leakage caused by the guttering on the houses blocked up and overflowing into the houses. Some of them would be roof damage, some would be glass damage," Mr Clarke said. +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ 016 Date: Sun, 02 Jan 2000 16:52:10 +1000 From: Anthony Cornelius [cyclone at flatrate.net.au] X-Mailer: Mozilla 4.6 [en] (Win98; I) X-Accept-Language: en To: Australian Weather Mailing List [aussie-weather at world.std.com] Subject: aus-wx: Yesterday's Supercell(s?) in SE QLD Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi all, Well...I saw a magnificant thunderstorm while showing relatives about yesterday in the Brisbane valley. I told Jimmy that I'm fairly confident that it was definately a supercell, as it definately appeared to be rotating (although we never got that close to it). There was at one stage, a "collar cloud" that had banded itself around in the midlevel(ish) area of the main updraft, underneath a RFB. This was not captured on video tape, but there is a short glimpse at an inflow band into the base, and a suspicious lowering underneath. But the footage is very brief, and it's difficult to discern whether it was a shallow WC or not...but we'll see. While going through the footage, there appears to be a long, thin, bended tornado - again, footage was only brief (thanks to forests/hills), but a little later, I have footage of the same scene, but it appears to be a long, thin and very well bended hail shaft (? focus kept going out because there was sometimes more foreground than background...should have put it on manual override, so it may just be a different intensity rain shaft). I have to go through the tape more closely, but I'm fairly sure it was just a hail shaft..mind you if it was, there was very strong outflow winds. The updraft was very strong and impressive, going up into a backshearing anvil. At times, there appears to be an overshoot...but you can't tell very well due to the other cloud. Because the terrain is so horrible, there's lots of brief 2-3second shots of the storm. Maybe I'll be able to go over to James' and use his video capture card and people can judge for thsmselves, but we'll see. After such an RS season, I was just ecstatic to see something that I thought was spectacular. I suspect this wasn't the only supercell yesterday either. -- Anthony Cornelius Queensland Coordinator of the Australian Severe Weather Association (ASWA) (07) 3390 4812 14 Kinsella St Belmont, Brisbane QLD, 4153 Please report severe thunderstorms on our Queensland severe thunderstorm reporting line on (07) 3390 4218 or by going to our homepage at http://www.severeweather.asn.au +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ 017 Date: Sun, 02 Jan 2000 20:02:28 +1100 From: Ben [bodie at flatrate.net.au] X-Mailer: Mozilla 4.7 [en] (Win95; I) X-Accept-Language: en To: aussie-weather at world.std.com Subject: aus-wx: BSCH Products Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi Everyone, Just wanted to inform the people that follow any of the BSCH products (forecasts, recent events or weather potential) that they will be updated again from tomorrow onwards.. we gave ourselves a holiday over the Christmas/New Year period.. and ISP problems tonight (Anthony and i are both with the same ISP) prevent the forecasts being updated..
