Actually it would've been better with the roof open to get some nice warm
sunshine. It was damn cold in the stadium, and when I left just before
11pm, it was noticeably warmer _outside_ than in, thanks to the cloud
cover.

At least we thrashed the South Africans though.

Regarding Atlantic Hurricanes it has indeed been very quiet Alberto is still
looping the loop around the middle of the Atlantic and Beryl died yesterday.
In the Pacific Wene (16W) has just crossed the dateline going the "wrong
way", Hector is almost dead and Ileana is still steaming along near Baja
California.
Ewiniar missed hitting Japan and should fizzle out in a few days.
Yesterday my page at http://www.drdisk.com.hk/cyclones.htm had links to
details of seven concurrent tropical cyclones.
The reason the media has not been too excited is because they have all been
sufficiently well-behaved to not threaten any American interests anywhere.

I am not quite sure what a "cold air Cb" is.  It is probably 
a cumulonimbus cloud that forms in some type of "cold"
environment.  Does this mean cold surface temperatures?
How cold?  Or, what about cold air aloft (how aloft? how cold?).
When does a cold air Cb transition into a mere Cb?
Are there warm air Cbs?

Yes, the U.S. (and almost any other non-tropical place [on Earth!]
that I can think of) gets convection during winter provided the 
lapse rates (and/or the lifting mechanisms) are strong enough.

In the absence of any damage the tornado-strength-by-damage Fujita
scale is useless.  If an "F5-equivalent" tornado touches down over nothing 
but solid granite it cannot be rated in the absence of other observations.
It would probably be logged as F0/no damage (or not logged at all).

A cumulonimbus in deep cold air IS a true TS - generally of the flash -
bang - gone type, or at least they are here. They spawn waterspouts and
tornadoes too, they're the main source of TN in the UK, apart from cold
fronts.

Plenty examples on the website, some amazingly shallow, follow the "severe
and not so severe" weather link.

The UK definition of a cold air Cb is: single cell TS formed in deep cold
air (generally in polar maritime air - NW in northern hemi, SE in Oz???).
Hence flash, bang, gone. Will post an example.

Polar Maritime Air = deep cold moist (made unstable airmass due to long sea
track over warmer seas) originating directly from Arctic (antacrtic)

Presumably it's the same in the US but Pm air is surely going to be
substantally modified by the time it reaches the centre(er) of the USA or,
for that matter, Alice Springs...

The main limitation of the Fujita scale made apparent - no damage = F0
although it could be rated T10. Perhaps the TORRO scale should be adopted
more widely! Enlightenment below (:

I made this argument a few months back; for "granite" read "reinforced
concrete", F5 damage in a timber framed and plasterboard house may not rate
F2 / T7 damage on a good old fashioned bricks - and - mortar structure
although it is liable to lose its roof and perhaps damage the walls somewhat
but not cause total destruction...

Hi Harald,
    Cold Air CB's, well my understanding of them is that they are cumulonimbus
clouds that for in a cold environment, cold upper levels aswell, these are also
the type of Thunderstorms that are normally in the Cold Pools behind a Cold Front.
Here in Perth WA, we get quite a few of these in the cold pool behind the cold
front, and yes we get Coldie's to ( Cold Air Tornadoes ) of which there has been
at least 4 Coldie's this winter alone here in SW WA, 3 of them in the Metro Area
here in Perth and one of them 5 mins walk from my house. Any one what to elaborate
further on Cold CB's/ Coldie's ???.

MJ.

Interesting looking rain band showing up on the SA radar at the moment
(11:30 AM 17/8/00). 
The current observations are showing Pt lincoln as having had no rainfall
at all but Ceduna has had 7mm since 9am, bureau is forecasting isolated
showers extending throughout later in the afternoon or evening.

from Bill, Proserpine, Q.

Hi all,

Maybe of interest to all you frozen southeners. I've put up data from our
AWS's (not as fancy as ASWA's BoM sites).

http://www4.tpgi.com.au/users/billwebb/bsesirr/mainlink/web%20weather.htm

It's still cool for us at night, but otherwise perfect!

The sites are within a 40km radius of Proserpine. I have plans to add a map
showing their distribution asp. We are using the data for irrigation
management, disease and pest outbreak prediction, and plant growth
modelling.

Regards,
Bill

Hi Les,

I know I'm going to ask a stupid question here - but I'm honestly not
sure...

How is the T-Scale better then the F-Scale as in, it does not rely on
the damage?  I thought both scales still required the damage to be
surveyed, and then an appropriate scale is evaluated from that?

Thanks,

Anthony Cornelius

Wow - that's some cold outbreak...

Even Mawson in Antarctica can only manage around -27C at 700m (around 10,000 
feet) today (late winter) with a surface temp of around -18C.

Sub-antarctic Maquarie Island has -22C at 700mb and a surface temp of +1C

For us deprived Southern Hemisphere dwellers, -30 at around 30,000m would 
represent a reasonable polar maritime airmass over southern Australia.

G'day all,

Too true Don, I think the endless supply of stats/records/trivia etc is
part of it. Also for me, it is the fascination with the impact of the
air/clouds/breeze etc, on the cricket ball as it is bowled. I LOVE
watching the art of swing bowling and Warnies drift etc.

As a youngster, I played baseball and cricket and whilst I didn't have
great success in swinging a cricket ball, I was able to get good swing
as a baseball pitcher. Not entirely sure why that was the case...I did
have a league injury (Broken/bent thumb) which could've helped.

Never straightened my thumb during delivery though. :-)

Hey guys,

I thought it was the fact that you got to see a constant supply of the sky &
storms in other parts of Australia - do you mean that you actually watch the
sport????? - (says she while being guilty of the fact that they couldn't get
me out on Sunday when I was batting in Sydney <g>) - I have always enjoyed
watching cricket in Brisbane (great storms) & Perth ( great storms like last
year <g>) - but strangely enough, when the cricket is in Hobart I can't be
dragged anywhere near a TV - ok, so I'll watch English soccer mid-season too
for the snow flurries, and then there's the Formula 1 if there's any weather
present too ...it's got nothing to do with the sport being played at the
bottom of the screen - it's the sky at the top that I'm interested in.....

ahem - 1027hPa here and blue sky............eyes to the west......

Hi everyone,
            Take a look at the latest New Scientist.  Bad news for storm 
chasers, good news for storm haters!  It's feature article is on how to bust 
tornadoes before they can cause damage.  An American scientist by the name 
of Ben Eastlund has proposed a scheme that might kill a tornado before it 
can form and cause damage.  The method is to heat the developing downdraft 
of a storm using microwaves beamed from a solar powered satellite from space 
since the downdraft of the storm is believed to be crucial in tornado 
formation.
Initial computer simulations have provided favourable results.
However, dealing with a chaotic system means it may be impossible to say 
whether the results of such a scheme can be verified.  But the whole idea 
rests on chaos - a small change such as heating the downdraft may lead to 
the demise of a developing tornado.
In many ways, the idea of controlling nature in this way parallels with the 
recent advances in gene technology and will raise a lot of questions about 
whether it may do more harm than good.
- Paul G.

Hi all.
I really have only one reason to watch cricket and that's the occasional pan
shots of the ground that allow weather scanning enthusiast to view any
build-ups on the horizon that may show any potential.

Hi Don and all,

You missed the 2nd innings of cricket on Sunday then!  The 1st innings
were played on TDU99 - halfway between Cunnamulla and Thargomindah (ie,
middle of whoop whoop).  The 2nd innings at Bicentenial Park at Homebush
Bay last Sunday.

I don't like cricket, although I did play (and batted twice, despite my
objects to "I will bat like a girl, ie worse than Jane!!!")  Not that
Jane was bad of course :-)  (How's the black eye you gave yourself going
Jane??? hehehehe)

Another cold, dry and windy SW'ly day here!  Not quite as strong as
yesterday arvo though, on the Gateway Mwy the winds were strong enough
to push the car!

Hi Everyone,

These are the best examples (from Brisbane) i could find of what i would
class as cold air Cb's

http://www.bsch.simplenet.com/pictures/assor/12-01-2000/12-01-200034.htm

http://www.bsch.simplenet.com/pictures/assor/12-01-2000/12-01-200072.htm


Those pictures are of poor quality (taken with my first digital camera), but
when i look at those updrafts i just think 'winter' ... i'm not really up on
all the technical explanations, but to me a winter Cb or updraft looks quite
different to a summer one

More pictures from that day are on this page - very  much a cold air Cb day
(the cold air that produced this activity actually stuck around for quite a
while, and we had 4+ Cb days in a row)

David,
        Yes the BoM have Doppler Radar in AU, but it is still in the testing
phase and has not been commisioned into service as yet, there are three
Dopplers in Au that i know of one in Darwin at the airport, one in Sydney (
yes it was there when the hail storm last april went through ), and apartently
there is now one in Melbourne to. On the subject of dopplers, Perth really
needs on asap with all the coldie's that have been happening ove the last few
year's, i think that the severe weather section here in perth is pushing for
on as we speak but whether / when and if they get one is a different story all
together. On the other question of  <snip> " Can inbound outbound wind
formations that form tornadoes be detected on reflectivity radar, without
doppler? " <endsnip> i think i will leave that one for our more experienced
ppl's on the Aus Wx list, Les Lemon ?? would you like to elaborate further on
this ?.

Oops....now I've tripped myself up over FEET!! The last sentence should, of

I might try and get it right 3rd time lucky!!

I meant -30C at 18000 feet (or 5.7km).

This is the last time I mention feet on this forum - all I seem to do is 
trip over all the left ones I have...

The Torro Scale is an extension of the Beaufort Scale and as such measures
windspeed and the damage it causes and not vice versa. It can also be used
in place of the Saffir - Simpson scale for measuring the windspeed of
tropical revolving storms.

Unfortunately it seems to be used only in Britain (and occasionally WA -
thanx, Ira)

Full info below:

Re cold air cells - the thickness the day that I took that small coldie was
528dm - please note the tephi showed a cold air INCURSION of -30C at 10000
feet.... I have the tephi for RAF Boulmer for the date I took the pic...

Would not want to be anywhere on the ground near where this microwave beam

will it do in terms of cooking humans?

I have just seen the 4-day forecast charts from the bureau of meteorology.   
Looks like Adelaide could see its first very intense low pressure system for 
winter on Monday.  Pressures below 990hpa.  Would be a great chance for some 
serious storm development.  I reaaly hope this forecast comes true.

It probably won't
We got low barometric pressures last week, down to 982hPa here and we just
got boring fine weather here in Christchurch whilst western regions of the
country enjoyed thunderstorms and even a *miniascure* tornado in Huntly in
the Waikato

Hi all,

The cold air cumulonimbus clouds brought some interesting weather off the 
NSW coast. James was ready with a camera and snatched a waterspout. He saw 
at least 4 waterspouts but his camera (I think one of the throw aways) did 
not do it justice.

I don't know all that much about NZ weather, but it sounds like you were 
unlucky.  But here in Adelaide when such an intense looking low pressure 
system heads our way we can be sure there will be some good weather events, 
unless we were very very unlucky.  What I meant was whether the position of 
the low will be where they are forecasting it to be, because if it is then 
the weather will be good (stormy), if it is further to the south then the 
weather could be more boring, (less stormy).  I suppose we'll just have to 
wait and see.

Are there two waterspouts in this photo? There seems to be a fainter one

Well, just speaking for me. Leave nature alone. Storms and any weather in
general are here/there for a reason. As far as I can ascertain, it's natures
way of trying to balance the temperatures across the entire globe. LEAVE IT
ALONE. As frightening as a tornado or any severe storm may be.

HI all - just finished watching the Weather Machine on Channel 7 - 
not a bad program at all!

One thing I got out of it was the importance of the Jet Stream - 
always knew that it played a part but not as significant as the show 
made out! Do we have models etc that forecast jet stream 
movement / direction?

Also - Darwins doppler is situated at Gunn POint which is about 30 
- 50kms North of the Airport. This is also a research doppler 
looking at a few issues:

a. Sea Breeze convergance (on Bathurst / Melville Island - the 
Hector storm has been known to produce tornado's )

b. Tropical airmasses & improving forecast accuracy.

Rgds, Paul.

Hello all,

Some weather humour from the students at Bukit View Secondary School,
Singapore.

There are more jokes from students and teachers around the world on the
Project Atmosphere Australia Online site at:

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

Sel Kerans.

______________

Don't knock the weather; nine out of ten people couldn't start a
conversation if it didn't change once in awhile! 

Probably the last completely accurate forecast was when God told Noah there
was a 100 percent chance of precipitation. 

If you see a heat wave, should you wave back??? 

Why not move the political conventions to one of the winter months, so all
the hot air won't go to waste??? 

And now, for your extended forecast: "Foooorrrcaaaasssstt" 

What's worse than raining cats and dogs??? HAILING TAXIS!!! 

It was raining cats and dogs one day last week, and I got my shoes all wet
when I stepped in a poodle!!! 

Climate is what you expect. Weather is what you get. 

Into each life some rain must fall, especially if you left the car windows
open. 

Most books say our sun is a star. But it still knows how to change back 
into a sun in the daytime.

Some people can tell what time it is by looking at the sun. But I have never 
been able to make out the numbers.

Clouds are highflying fogs.

I am not sure how clouds get formed. But the clouds know how to do it, and 
that is the important thing.

Clouds just keep circling the earth around and around. And around. There is 
not much else to do.

Water vapour gets together in a cloud. When it is big enough to be called a 
drop, it does.

Humidity is the experience of looking for air and finding water.

Rain is saved up in cloudbanks.

A blizzard is when it snows sideways.

Thunder is a rich source of loudness.

Isotherms and isobars are even more important than their names sound.

It is so hot in some places that the people there have to live in other 
places. 

The wind is like the air, only pushier.

You can listen to thunder after lightning and tell how close you came to 
getting hit. If you don't hear it, you got hit, so never mind.

Hi Paul, Phil and everyone, 

Statistically, it actually appears to be the norm for active Atlantic
hurricane seasons to start late. Typically, you will see very little if
any activity before the end of July, and so things aren't really too
unusual over there just yet. As you say Paul, last year was above average
both in terms of hurricanes and major hurricanes, but it did follow this
pattern as well. The first hurricane of the season was Bret, which formed
on the 18th of August. We can expect to see some action over there pretty
soon if all goes according to theory.

Cheers,

Jonty.

I hope the low will end up where the BoM is forcasting for your sake.  Good
luck

Anyway, it's looking good for your region for the middle of next week as
another low forms to the south of Aussie according to NOGAPS and EC. Little
anticyclonic activity (or should I say in-activity!) in sight, although
anticyclones are good at directing interesting weather forrms.
Upper levels look OK too.
