I think it's some measure of the stability of recent wx in your area,
Paul. In stable, fine weather situations, the minimum will normally
occur around half an hour after sunrise, as it takes this long for the
rising angle of the sun to put in more radiation than is going out.
The timing of the maximum is usually more variable, as even in fine
weather there will usually be more variables (cloud, wind) around at
the normal time of maximum -- early afternoon -- than just after dawn.
One thing I've noticed, though, which Blair might like to comment on,
is that different locations appear to favour different times for the
average occurrence of their maximum temp (I haven't noticed this so
much with minima.) Factors such as sea breezes in coastal areas (and
the lack of them in inland areas), together with aspect would account
for some of this.
Still, having three consecutive minima at precisely the same time is,
I think, something of a statistical anomaly. Were the weather
conditions also the same each of those mornings, Paul?

Current (9.30am) radar shows large area of 2>10mm/hr over northern and
western Sydney with spots of 10>20 just north of the Harbour. I'm at
Drummoyne, and am now having the second heavy shower in an hour --
probably around 15mm/hr. The radar shows everything's moving from the
ESE, and there's quite a lot more out to sea.
Get the wellies out!

Just heard a report, on abc radio, of a 'mini-tornado' accompanied by
swirling winds which went through a town (M... cant remember the name)
about 200km north of Perth. Anyone with more details?

Hey Ben from Brisbane here ..
I know this topic has come up before, but the question was asked last night (in
the IRC meeting) exectly why they dont get hail in the tropics? Maybe someone
can post a few links on the subject, or give a more in depth reason as to why
they dont?

Ben,
Earlier discussion indicated that hail does occur in the tropics, quite
frequently in the north Queensland tablelands. You will have to look
through the mail archives to find more. I don't have any links to articles
on the subject though.

Ben, the main reason is that there freezing level is much higher then
the freezing levels down south. This means that the hail will be
exposed to above 0C temps for much longer. Occassionally the tropics do
receive hail, but it's very rare. I queried the BoM about hail, and
they said the Darwin office has never received hail for as long as it's
been in existece, but some of the suburbs has received rice grain hail.
Not to mention that without the jetstream, many storms will collapse on
themselves before strong, sustained updraughts can occur and make the
hail.

Hi All,
I've been lurking on this list for a couple of weeks and it seems to be the
done thing to introduce oneself so here goes...
Lieutenant Jim Crouch, RAN
Officer in Charge
Applied Meteorology and Oceanography Centre
Maritime Headquarters (MHQ) Australia (Sydney)
BSc Oceanography UNSW (ADFA Canberra 1989)
Grad Dip Met (BoM Course 39 - 1992)
MSc Physical Oceanography (NPS Monterey Calif 1997)
Spent about 2 years at sea driving a Patrolboat prior to Met Course then 3
years forecasting (Aviation and Maritime forecasting at both NAS Nowra &
MHQ) from 1993-6. Last year I was Staff Officer (Oceanography) here at MHQ
and this year I am responsible for the acquisition and development of METOC
(Meteorological and Oceanographic) products and services for the Navy and
for METOC training in the fleet (amongst other bits and pieces). Still keep
my hand in forecasting doing the odd watch "on the bench" now and then (we,
the RAN, have a full link to the BoM getting all their data. Should [touch
wood] have AIFS up and running by the end of the year).
Saw my first water spout Aug20 last year (thin "rope-like" thing that I
couldn't even see through the view finder of my Kodak disposable) out of a
not particularly impressive flat based Cu Type 2/3 somewhere in the Solomon
Sea. Lasted about 2 minutes while I was trying to convince the CO that we
should get closer so I could get a photo of it.
That's me, that's it.
Jim

Not sure what you're meaning by Tropics Ben, but this may be interesting to some.
My hometown of Ayr, nth Qld, seems to get hail on a far more regular basis than
it did 20 yrs ago...
We were treated to a huge hail storm (golf ball size on av.) when I was about
14/15 .. came completely from out of the blue.. the skies didn't even look
mean...they were just plain grey, I recall a gentle breeze ... according to my
Mum at the time, she'd never seen hail in the area ever ... and she was about
50 then! . in the last 10 years, I would say that Ayr has seen hail probably
once a year at least ...
unfortunately I've been living here in Brisbane all that time, and I've only
seen hail here at The Gap, twice (pea to marble size) just 4 years ago, and once
last year .. Yet other areas of Brisbane have been pummeled regularly....
on one occassion Kedron/Chermside areas were with meter deep hail?..
anyone remember more about that one? .. was a few years ago now...

I think it was Easter 97...when one of the shopping centre's doors caved
in because of the hail drifts, and Myers (I think) had it's first 'hail
sale' :)

Most people on the list would know the recipe for hail:
1) Strong updrafts (vertical velocity)
2) Continual recycling.
3) Freezing level within recycling alititude.
4) Super-cooled condensed water in clouds above freezing level.
Now for the records:
1) Great Britain - 15 May 1697, Offley, 140mm, weight?
2) USA - 3 Sept 1970, Coffeyville, 190mm, 766gms.
3) World (Bangladesh) - 14 April 1986, Gopalganj, size?, 1kg (2.25lbs)
4) Australia? (Blair?) 1976 saw a hailstorm in Sydney causing $40M
damage.
5) Germany - July 1984, nearly $1B damage.
I could also go into deaths but that's awful with the worst being
recorded in the Moradabab and Beheri districts of India on 30 April
1888 which sported cricket ball sized hail that killed 246 people and
over 1600 animals:-(
The tropics do get hail sometimes but most of their storms are not
spawned from the supercells that delivered these monsters. I would be
guessing here but I'd say it has something to do with the ferocity and
cyclic nature of the updrafts in supercells that is worsened by the
collision of warm and cold air masses in the sub-tropical and
temperate regions that is largely absent from the tropics.

Just one other thing - elevation plays a lot to do with it, if you're
living on a hill/mountain, then the rules are different because if your
1000m high, then that's 1000m less time for the hail to melt for
example. Not to mention, the closer you are to sea level, the warmer it
gets. Most of the melting occurs in the lower, surface levels, as this
is where temperatures are warmer.

It is easy to get wrong estimates when you are not used to rain or storms
for a long while. Further, you are also likely to get more busts whilst
storm chasing when storms are scarce.

This from ABC news.
Mini Tornado and bushfires in
WA's wheatbelt
Thursday 21 January, 1999 (12:40pm WST)
In Western Australia, firefighters are still trying to quell a fire in
national parkland north of Perth, apparently started by lightning
last night.
Officers from the Department of Conservation and Land
Management and fire brigade crews are battling to control the fire
in the Watheroo National Park, while fires on nearby farmland
have been put out.
The storm coincided with a mini tornado which ripped through
the small wheatbelt town of Miling 200 kilometres north of Perth
at about 5:00pm.
Swirling winds, accompanied by torrential rain, tore the roof off
the local tennis pavillion, damaged the roofs of several houses,
and cut power and phone lines to Myling.
But nearby towns weren't touched.
----
The storms have moved east today, and there is a severe thunderstorm advice
for some inland districs again today. Also, a lot cooler in Perth today,
after yesterday's 39C. But the heat should be back this weekend again.
OUTLOOKS FOR PERTH FOR:
SATURDAY: Fine. Hot. Max 36
SUNDAY: Very hot. Max 39
MONDAY: Very hot. Max 39

Kev,
If it hit you, you wouldn't even be alive to measure it:-) Source of
info is a book by Paul Simons entitled "Weird Weather", published by
Warner Books in 1997, page 150, second paragraph.
Maybe our resident weather-data-facts hound, Blair, can confirm or
otherwise state another record. As for the Kansas monster of 766
grams, "it was preserved in a freezer and sent for verification to a
government research laboratory in Colorado". Dimensions were 190mm
diameter and 440mm circumference. It was just about 234 grams shy of
the world record claimed...Now as for cricket in the Indian
sub-continent...

Does anyone have any data on what IR1, IR2 & IR3 mean in terms of the
Infra-Red wavelengths detected and the correllation that would have
with temperature?

Hi All,
Two storms at present. One South over about Blayney with a small amount of
lightning. Another NW I would say over Peak Hill/Narromine with a lot more
lightning. Still scattered cu in Orange with no local action.

Unfortunately, this area doesn't have much in the way in radar
coverage.
There are a few interesting lines building up on the radar - one
stretching from Tamworth to Moree, another west of Wagga, another in
the Albury area. Also more extensive rain along the NSW coast.
(Sydney area rain in the 6 hours 0900-1500: 43mm at Observatory Hill,
but 63 at Homebush and 60 at Riverview).

Wamer and more humid in Melbourne today. Currently in Kilsyth it is 27c Dew
Pt 15c. Scattered Cu. Tcu and very distant Cb to the NE. Faint but frequent
static on AM Radio. Beechworth and Yarrawonga were reporting Thunder at 3pm
and Wangaratta was reporting Hail. So it looks fairly active in NE Victoria
at the moment, unfortunately cant get an updated Sat Pic at the moment.
Good chance of Storms over much of Victoria during the next two or Three
days. Dane

Hi all,
I've just come online after two thunderstorms that have passed through here
in the last hour and a half. The main storm cells are now to the east of
Albury, very impressive with the sun now shining. There are also some build
ups out to the north towards Holbrook and another buildup to the northwest,
this one developing quite nicely I think. We'll wait and see!
Earlier, continuous thunder alerted me to some action. A large cell moving
eastwards to the south of Albury was producing alot of CC lightning, as many
as 3-4 a minute.
Shortly after a smaller cell came overhead. The lightning was very close.
One flash lit up the house with the crash coming before I had a hance to
count one. Only a few gusts in this storm, with a light shower for about ten
minutes.
After this the tail end of another storm to the north passed over with more
lightning relatively close, a number of CG's going down on the nearby hills
towards Lake Hume. This time however, constant heavy rain for about fifteen
minutes. All the gutters were overflowing on the houses nearby, including
ours. No hail.
Temperature here dropped from 30.4 to 20.6 within the hour.
ALI AWS has the rainfall in Lavington at 1.6mm in the period, I believe here
there was more, but don't have a guage set up.
The sun is now shining and it is very humid. The main storm out to the east
of Albury is providing a great show at the moment.
Good Luck to any chasers going out tonight and over the next few days.
Things look on the up for this part of the world.
Cheers
David L (Thurgoona, near Albury)

I have to say that this kind of reporting really annoys me ...
mini-tornado... swirling winds ...
If a vortex of winds, whether visibly condensed or not, occurs during a
storm, and comes into contact with the ground, is this not a tornado ...
words like 'weak' or 'small' would be better used than 'mini' ... dont
you think? A tornado, is a tornado.
It's damage defines it's size. There does not have to be a lowered wall
cloud present for a tornado to occurr.
Why is it the Australian weather industry struggles so with the use of the
term 'tornado'??
Maybe it's just me...
rals!

Thanx Laurier...as usual your a wealth on information. Yes the conditions
have been the same for a few days now......(til last night).
Very hot days, strong NE then clear warm humid mornings...
Something u will also be interested about:
The storm yesterday did not move very far, but I believe that there were
some large falls between Wingham & Gloucester with some falls exceeding
70mm? Wondered if you had heard anything about that? Maybe the same for
today with them being total under this cloud mass, while Taree & est moved
in and out all day. But it is very humid here at the moment....70%
inside...more outside.
Regards, Paul.

Hi all,
I set up an automagic download of water vapour satpics from;
ftp://geo.msfc.nasa.gov/Weather/GMS-5/gif/mapped/wv/globe/
then using UNIX software (whirlgif, xanim) that converts 90 x 290Kb
gif files into a new animated gif file of about 25MB that runs a
"movie" of nearly 4 days in about 10 seconds. This shows where most of
the circulation of water vapour is happening around Australia.
Seeing is really believing as it comes "alive". You see Northern
Australia and individual major cells develop and dissipate from day to
day. It's like a bomb going off each day - simply spectacular. It is
easy to pick up the upper level wind sheer taking place in the top of
major storms and the feed of moisture into the rain around Sydney
today plus the circulations around developing cyclones in the Coral
sea and Pacific Ocean...

Hi all,
I'm in total agreement with you, but there's a lot of confusement with
terminology between the media and the public.
Often we'll here of a "mini tornado" or a "mini cyclone" ripping through
some suburbs or a small town. Quite often, the damage with this is
associated with strong microbursts. However, there are a lot of
instances when it is a tornado, such as Oct 13 in Brisbane, the media
described it as a "mini tornado."
One of the reasons why tornadoes aren't mentioned as often as they
should be is because of the lack of knowledge of the Australian public.
If you ask anyone on the street if Australia gets tornadoes, 98% of them
will look at you as if you're stupid and say "of course not, only the US
gets them." If a 'tornado warning' was issued for an area, you'd create
panic!
I know the Brisbane BoM is not calling the Oct 13 incident a tornado -
despite a visible condensation funnel halfway to the ground with
swirling, rising debris caught on video tape. The plethora of funnel
sightings reported near the area, and the well defined hook echo
visible. Apparently some person from Sydney said it wasn't a tornado,
so that's how it's going down. But I don't know what the full story is,
but that's just what I got told.
Channel 10 said the Caloundra tornado in Nov 24 last year was the first
one in the QLD in 25yrs...with was ludicrous!!! Again, the media
feeding into the web of myths in Australia about tornadoes.

..y'know, sumwun oughta send those media guys a copy of "Willy-willies

tornadoes in the world, US being #1.
You can write away for this book by the way - for anyone who doesn't already
have it. It was $17.50 when I got a copy for someone last year. (postage etc

Hi Jimmy here,
You are not the only one, Narelle. The lack of understanding in terms of
the use of terminology by the public, media and other members of the
community particularly those in more professional fields really disappoints
me. Even more so, we are always left wondering what really happened. Was it
just a severe storm, microburst or a tornado. I suppose it is up to us ASWA
to address this and educate the community of what really happens.

Hey Melbournites,
look out your windows to the NNE/NE - there are a couple of nice cells going
up.
Clyve (our 'on the ball Victorian weather-spotter-on-the-move') has just
rung in to report it & I'm off with camera and video.
Give me a ring on 0411 455 100.

I heard it on the ABC news this afternoon where it was correctly
reported as a tornado rather than a "mini tornado". It's not often that
they report these things without describing them as "mini"...

Loaded camera & dog into the car and drove a couple of kms towards Mt
Dandenong to a nice clear spot with a great view to the north. Cells fairly
high based and glaciating at low levels over the Kinglake area in the hills
NE of Melbourne - short sharp punches - and then nothing. Development at
the NW side of the cells heading to the SE. Got a couple of possibly nice
shots - but nothing dramatically good. Showers showers were shortlived,
light and random.
Nice portent for tomorrow guys!! A definite goer for coffee up Mt Dandenong
after work.

Due to me being silly enough to use 2 computers 26 kms apart, I've got a
couple of email addresses on the *wrong* one.
Does anyone have an email address for Brian Weldon of Gembrook handy??
We're also doing a bit of a recruitment drive for the Victorian ASWA meeting
via web pages (anyone got Paul Yole's URL or email in western Vic?) and the
unis, csiro etc etc.
Trying to get as many people as we can involved down here initially.......

Thanks to all for your help with the email addresses.
I'll send the aussie weather location etc list in the next day or so and

to all for letting us know your details.
If you haven't already, could you please let us know your name (the real one

Thanks all,
Jane

Nope. It ain't just you.
This is a cultural thing that seems to have built up alot of inertia over
time. Its got so bad that an F3 dropping right over the harbour bridge in
front of 50 journo's would probably still be called a 'mini-tornado'! (of
course, we all know real tornado's only occur in the US).
It's one of the things that this group might help change, given enough time...

I have to say Kevin that I do accept reports of such enormous hailfall
in Bangladesh. The storms, supercells that is, in that country are in
all likelihood the most powerful on earth and develop in environments
with trully phenomenal CAPE - in excess of 8000J/kg which is much
higher than that in which the US midwest storms develop and certainly
also much greater than anywhere here.
Also as far as the record hailstone diameter in Australia, I recall
having read a report of a 14 cm hailstone which fell from 1996
Armidale supercell - which I think was the largest on record in this
country. Also, there was a report of a 12.2 cm hailstone near Tamworth
last season but that was thought to be a conglomerate of smaller stones.
Cheers
David
