Hi all,

Michael T - was in at the Sydney BoM this afternoon and heard that some
hail had been reported from around Wollongong. I saw some great rotating
lowerings and lifting scud as the gust front went over Kurnell -
Sutherland but it had stoped by the time I got to a good vantage point!

I am currently seeking out permission to post to the web a panoramic
view that was taken at Lucas Heights this afternoon - it's a corker!

Andrew.

Hello All!

I posted recently, on a topic which hinted at relationships between jet
streams, severe weather events and radio propagation.

I'm sort of in the middle of things here, and am finding out more with each
exchange.  Anyway, the basic gist of what is happening is:

One or more radio amateurs is studying the possible causes of a condition in
the atmosphere known as "Sporadic E" propagation, where a specific layer of the
upper atmosphere becomes heavily ionized.  This condition causes signals within
a certain frequency range to propagate over distances greater than normal (any
Melbournites seen TV channel 0 Toowoomba lately? :) ).

Despite being known for a long time, sporadic E is still poorly understood.
However, there are some people who believe it may be caused by weather events,
rather than solar radiation or other factors which are traditionally assumed to
cause sporadic E.

We will probably be looking for historical data on jet stream activity over
Australia and/or severe weather events.  Is there anywhere I can get hold of a
summary of such data that may be useful for this investigation?  I will be
posting more, just waiting for permission to do so (the discussion is in
private email now), and any other information that may help.

Any help would be appreciated on this one, you could be helping to solve a very
old mystery of the airwaves. :-)

Tony, VK3JED

I notice that Sydney (Obs Hill) had 17 mm in the 10 mintes to 4.16 pm
(actually 16.8 mm or 101 mm/hr). From observations in the area, it might
have fallen in less time. It will be interesting to see if BoM makes
available any pluvios etc.

Second hottest summer on record for Adelaide, only just beaten by 1905-06.
Hottest night temperatures on record I believe.  Driest summer in 9 years
too.

Thank the weather gods it seems a bit autumnal now......

Hi all,

Nick Moir a member of ASWA and also a photographer with Fairfax assures
me that there will be a colour photograph on the front page of the
Sydney Morning Herald Thursday of the squall line approaching Sydney.
There will be a mention of ASWA in the short passage of the article.

On another note, the article about my involvement in storm chasing in
the Good Weekend will be in the 10th March edition apparently. I hope
there has been a mention ASWA and ASW in that article as I had mentioned
several times to put the URL in. We shall see though....

Hi Tony & everyone,
                                Sounds interesting...In my ARRL antenna book
(1960's but still useful - I received 2nd hand from a relative), it suggests
sporadic E is somehow related to stratospheric winds.  Although, as you
suggest, other factors may well be involved.  Perhaps even thunderstorm
activity.  Recent research has been looking at jets of ionised gas (sprites
as they are known, I think)  at the tops of active thunderstorms.  Maybe an
archive of satellite photos would be useful?  This way you can also see
where thunderstorms have been, not just jetstreams.  For example, water
vapour images will reveal jetstreams and thunderstorms as they provide a
view of the upper troposphere.
Good luck with your research.
Paul G.

Has anyone seen the front page of today's Sydney Morning Herald?

It shows a pretty awesome shelf cloud in one of the storms that crossed 
Sydney yesterday afternoon.

Right now, a very dark (yet small) cumulus congestus about to possibly dump 
a fair bit of rain just to the west of Coffs Harbour.

Haven't got the state/regional averages to hand (and the person who
normally runs them is away this week), but some numbers for the major
cities:

Melbourne

Mean max	28.1 (3rd; highest 28.3 in 1950-1, 1897-8)
Mean min	16.9 (highest; previously 16.8, 1980-1)
Mean		22.5 (highest; previously 22.4, 1980-1)
Rainfall	57.8 (6th lowest)

Adelaide

Mean max	31.3 (2nd; highest 31.4 1905-6)
Mean min	18.6 (1st; previously 18.3 1967-8)
Mean		24.9 (1st; previously 24.7 1897-8)

Sydney

Mean max	27.3 (3rd; highest 28.5 1990-1)
Mean min	20.2 (equal 2nd with 1997-8; highest 20.7 1990-1)
Mean		23.7 (3rd; highest 24.6 1990-1)

Interesting that the three highest mean max values (which are not
affected by urbanisation to the extent that the mins are) have all
been since 1990.

Canberra

Mean max	28.8 (5th; highest 29.9 1990-1)
Mean min	14.0 (equal 3rd; highest 14.8 1980-1)
Mean		21.4 (5th; highest 21.9 1990-1)

Hobart

Mean max	23.2 (2nd; highest 23.3 1894-5)
Mean min	13.3 (1st; previously 13.1 1970-1)
Mean		18.2 (1st; previously 17.7 1994-5)
Rainfall	53.4 (6th; lowest 34.3 1897-8)

The January-February rainfall for Hobart of 12.2mm is the 2nd lowest
on record, after 9.4 in 1914.

I've now got hold of the regional anomalies for summer. Notable
ones are:

Southern Aus	max	+1.44 (1st)
		min 	+1.56 (1)
		mean 	+1.50 (1)

SE Aus		max	+2.49 (1)
		min	+1.76 (2)
		mean 	+2.13 (1)

SA		max	+2.58 (1)
		min	+2.74 (1)
		mean	+2.66 (1)

(the SA figures were all records by at least a full degree!)

NSW		max	+2.15 (1)
		min	+1.58 (2)
		mean 	+1.87 (2)

Victoria	max	+2.50 (1)
		min	+1.65 (2)
		mean	+2.08 (2)

Tasmania	max	+1.89 (2)
		min	+0.79 (7)
		mean	+1.34 (3)

February figures were mostly high, but not as spectacular, but SA
set records for minima and monthly mean, and Tasmania for maxima.

On the other side of the coin completely, Liawenee got -4.8 this
morning, missing the Tasmanian March record low by only 0.3 (and
this was on the 1st of the month). The new AWS there looks to be in 
a colder site than the already cold former site and is worth watching.

Thanks Blair for the info in your posts..

A question I have had for some time is whether there is an increasing 
frequency being observed of new record high temperatures (as might be 
consistent with a climate warming trend for Australia)and any decrease in 
frequency of new record low temperatures?

Or are frequencies of records at both ends more or less stable and more or 
less evenly balanced (as might be indicative of relatively stable climatic 
conditions; and the fact that accurate and systematic recording of 
temperatures is a relatively recent - in climatic terms - phenomenom)?

Is such data available?

Thanks Patrick

Hi Lindsay,

On the BoM sounding there's 2 plots.  The red is the current/most recent
sounding.  Its time/date is written at the bottom in red.  The right red
line is the temperature, the left red line is the dew point.  Along the
bottom and top horizontal axis, and the right vertical axis is the
temperature.  These can be read at any given level by following the
diagonal lines to a certain temperature.  The left vertical axis
displays the pressure height.

For example, to read the 500mb temperature, simply find the right
temperature line and where it intersects the 500mb line.  Then following
a diagonal brown line to a temperature.  Just follow the same diagonal
pattern to get temperatures outside of the 10C intervals.  However the
500mb level has 2C tabs on it to help you work it out.

The grey line is the current OR forecast theoretical air parcel plot
line.  If you want to know how to plot this - just ask :)

The blue line is the previous sounding, the right blue line is the
temperature and the left blue line is the DP.  This is useful in that
you can easily compare the previous the sounding with the current
sounding to work out if things are drying/moistening and warming or
cooling.

On the right are the winds.  The strength is measured in barbs.  Half a
barb is 5kn.  A full barb is 10kn.  A bold/thick barb is 50kn.  It also
indicates the direction.  The top of the page is "north," the end of the
line with the barbs on it is facing the direction the wind is coming
from.  So the barbs are on the line facing the left, the wind is from
the west of 270 degrees.

Hope this helps!

That's a useful suggestion.  Sprites are obviously an ionization phenomenon,
and would be a possible culprit.  At this stage, we are suspecting multiple
possible causes.  Stratospheric winds are still a possible culprit.

Our aims are:

1.  To understand Sporadic E better
2.  Predict possible openings in advance, as we can with ionospheric F and
tropospheric ducts/inversions.

OK, thanks.  I can see I'm going to have to broaden my weather interests and
learn a bit more meterology to carry this one through, but that's only going to
be for the better. :-)

On that score, does anyone have any records for severe (or other significant)
weather events that occured last Saturday (any time of day), location and type
of event...

There was one or more major sporadic E openings that stretched from Melbourne
and Adelaide to Brisbane during the day, and later in the day, it was most
pronounced over S.E.  Australia - Melbourne, Sydney, Adelaide.

Hi all,

Some showers and TS around in NE NSW and SE QLD today.  The sky had
hinted at something later on - and when some showers developed on the
border ranges I was getting a little excited.  I drove down to
Beaudesert and saw several large showers/small Cb's precipitating.  One
eventually took my eye to the SW of Beaudesert.  This gave rain rates
between 100-120mm/hr!  Could hardly see the road!  On the western edge
of this cell, I received strong winds (30-35kn), strong enough to break
off some small branches (very small...one foot or so!) off trees, but
the winds were brief.  

Still, better than nothing!

We are continuing through our period of marginal possibilities for the
next few days.  It will be better on the ranges and further west
though.  Oh well, we can only see and hope that we get a few more days
like this - or even better, days where we can see flashes of lightning
and hear rumbles of thunder! :)

Can't complain though!!!  (Sort of ;)

For anyone who's still awake in the Illawarra there's some rather tasty
stuff heading over the Southern Highlands towards Wollongong at the
moment.. might not be anything much stormwise but there's patches of
green in there.. maybe time for some nice nighttime lightning shots :)

I've spent a fair part of the last six years looking at exactly this
question in my (hopefully) soon-to-be-completed Ph.D thesis.

Whilst I've been looking at the frequency of temperatures above and
below certain thresholds (both fixed and percentile-based) rather
than the frequency of record-breaking, the results, I imagine, are
still of interest. These show that the frequency of extreme high 
(defined as those in the top 5% or 10% of the overall frequency
distribution) maximum and minimum temperatures are increasing, and 
that the frequency of extreme low maxima and minima is decreasing,
over the 1957-96 period. The trend is strongest for low minima, and
considerably weaker for high maxima than for the other three indicators.

Generally speaking the trends are strongest in winter. In the case of
low minima the trends are especially strong in Queensland; for low
maxima there is a marked decline in the winter half-year in areas 
exposed to the winter westerlies (Tasmania, Victoria, southern SA).
The trends tend to be weak or non-existent in summer and autumn in 
much of south-eastern Australia (this goes for means too), although
the data set I used finishes in 1996 and the succession of very hot
summers since then in that area may shift the long-term trend.

Had a storm here at 7am this morning. Thunder and some moderate rain,
best stuff developed out to sea though.

The good thing, is that it has now cleared, and we have sunshine galore.
If this keeps up and with the trough hanging around we should see some
more storms here in Sydney this arvo..
*fingers crossed*

Hi Matt

Similar situation in the Illawarra. Already( 10.30am ) there is convection
occurring everywhere, including that rarest of all - over the coast even.

Had a storm here at 7am this morning. Thunder and some moderate rain,
best stuff developed out to sea though.

The good thing, is that it has now cleared, and we have sunshine galore.
If this keeps up and with the trough hanging around we should see some
more storms here in Sydney this arvo..
*fingers crossed*

<x-flowed>
Hi all,

I could add a further word on the grey line parcel on the BOM sounding and 
the resultant Lifted Index (LI), since that is my work. Traditionally on 
web soundings the environmental surface temperature and dewpoint are used 
as the 'baseline' for the lifted parcel. The advantage I suppose is that 
everyone will come up with the same LI value. However we (weather 
forecasters in South Australia - I'm from the SA BOM) preferred to try to 
estimate a typical afternoon parcel, so that the LI would be more 
representative of values at the time of maximum convection. This has the 
effect of producing much lower LI's than you might typically see calculated 
from other Internet sites.

1. The method I chose to estimate the 'afternoon' surface dewpoint was to 
simply mix the lowest 50hPa moisture in the trace. This is a fairly 
traditional method which tries to take into account convective mixing and 
some kind of surface evaporation. It works surprisingly well.

2. The afternoon temperature is more problematic. We chose originally to 
simply take the temperature at the top of the 150hPa surface layer and 
bring it dry adiabatically to the surface. This does not work in very moist 
situations, so I modified the method slightly. If the line of constant 
mixing ratio of the calculated parcel surface dewpoint crosses the 
environmental temperature sounding within that 150hPa surface layer, the 
temperature of this cross-over point is taken instead of the top of the layer.

I hope that makes sense. This morning's Sydney trace shows what I mean. 
It's a nice rain saturated trace.

         http://www.bom.gov.au/products/reg/IDS65024/IDS65024.94767.shtml
                         (user: bomw007 password: aviation)

The 18.6C parcel dewpoint is calculated by mixing the environmental 
moisture in the lowest 50hPa. For the temperature I would normally have 
taken the temperature of the sounding 150hPa above the surface (about 14C) 
and taken it adiabatically down to the surface producing a parcel surface 
temperature of 27C or 28C. However the parcel mixing ratio line crosses the 
environmental temperature at 944hPa which is within the 150hPa layer. I 
therefore take this as the LCL thus making the surface parcel temperature 
23.6C. Looking at the Sydney METARS at showing precipitation and 8 octas of 
cloud and a temperature of 22.7 at 2330, 23.6C is not a bad 'guess'.

I have found that this method works reasonably well. It fails miserably in 
very dry situations, particularly when solar radiation would not mix the 
lowest 150hPa. Examples are the Antarctic soundings. It's hard though to 
produce a simple method that works over a wide geographic and seasonal 
range. As the LI is mostly used for TS forecasting I have chosen a rule 
that works well in typical Australian convective situations.

I apologize for the use of jargon which I don't explain, but if this 
monologue gets any longer no-one will read it.

Cheers
Hank

He he,

Wouldn't be too many on the list old enough to remember that Michael...

The 9:30am IR pic on the BoM site shows amazing structure for something
which has travelled so far over land.  But the models do not seem to think
that it will move out to sea, rather just decay over WA.  But these things
seem to have a mind of their own of course.

Stunning indeed Jane.  When I saw the first email, a few days ago, about
stunning images of Abigail, I thought it was someone passing on soft porn
images of the former 96 star!

I wonder if Abigail will do a Steve by following the Coral Sea-Indian Ocean
trail he blazed last year?  Time will tell.

I am certainly not pulling the links to Ex-TC Abigail from my site 
(http://www.drdisk.com.hk/cyclones.htm) until she shows a lot less 
organisation than she currently has.  My guess is an eventual wander out 
over the Indian, but who really knows?

And I still clearly remember Abigail of 96 but hadn't realised that it 
was all that long ago!

Hank,

there are sooooooooo many copies of the Snow White virus running around atm,
that it's nigh impossible to keep track of them.  Quite often now they will
turn up at a totally different time to any other email that you may
receive - I think a good virus checker program & a fast delete key are the
best ways of keeping this particular one under control.

We actually called one-net last year to inform of this (we get the snow
white virus about a dozen times a day) and they looked into it. Their
findings were that they were being spammed and the virus was not coming from
one-net at all. We have also noticed that the virus can originate from
several different servers - all of which are probably faked addresses.

So we just block the messages and forget about it. Tracking down these
losers is next to impossible.

Gday all,

Quick call from Dann confirmed what Sydney chasers weer hoping for !! TCU 
everywhere.
Dann has a big cell with a strong Anvil north of Katoomba in the Blue 
Mountains. There is also, according to radar, some big cells that have 
formed On the hills behind Ulludulla and are now Pink/red just near Nowra 
heading due north... Could be intersting for Sydney later. There is also 
plenty of Cu over sydney at the moment that seems to be getting bigger.. 
heres hoping !

On other thing to note is the big cell out to see of the Moruya coast ... Im 
only looking from Radar but does anyone else thinks it looks very Sus 
Supercellish ?

The panorama I promised is now at

The centre of the photo looks east. The neon glow came out brilliantly.

It could be a very interesting afternoon in that the cells are heading
South -> North which isn't the most common scenario...

Hi all,

Just a question to throw out there amongst you all.  I had a thought
(provoked through reading it somewhere) that gustnadoes didn't actually have
cloud base rotation and that it was more surface voriticity that lead to
these features.  I'd be interested to hear peoples thoughts/comments on this
statement.

Regards,

Andrew McDonald.

Hi all,

From looking the BoM's four day forecast charts and GASP models, I would
say there is an outside chance of an ECL developing next week. Certainly
hope so - that would be our first in about a year now (not counting the
questionable one that caused one of the snow events last winter).

Andrew.

Hi all,

Nick Moir a member of ASWA and also a photographer with Fairfax assures me 
that there will be a colour photograph on the front page of the Sydney 
Morning Herald Thursday of the squall line approaching Sydney. There will 
be a mention of ASWA in the short passage of the article.

On another note, the article about my involvement in storm chasing in the 
Good Weekend will be in the 10th March edition apparently. I hope there has 
been a mention ASWA and ASW in that article as I had mentioned several 
times to put the URL in. We shall see though....

I am off to bed - still ill from the hard  day I had :)

Hi Paul,

That is excellent news to hear It seems that Darwin was located on the NE 
quadrant of the low so I would say it should still apply to that area. Was 
the tornado from a supercell - mesocyclone detected? Could you post some 
radar images of the event please?

Thanks

Hi Blair and all,

Thanks for all of that, it makes for fascinating reading. I'm sure there's
plenty of us on here that enjoy reading these particular posts. It's been so
warm (especially during the night) here in the mountains, warmer than I can
ever recall and indeed one of the warmest summers ever, at least on local
anecdotal evidence, as my records don't go back far enough.

Can anyone tell me the impact such warmth might have on the SST for the lead
into winter? Its pretty warm around the Bight at the moment but there is a
cold-ish large pool of water to the west of Australia, that might move this
way. Lets hope it does as apparently we need average or slightly cooler than
average SST's for a decent winter. I know its a long way out for winter but
anyone got any thoughts for the upcoming season, compared to last year?
There's certainly plenty of moisture around.

Cheers,

Lindsay Pearce

Hi all

Like Joy, I'm getting a bit frustrated with Melbourne's weather..... 
....way too fine and sunny, what's the deal with that?!? If it weren't for
people posting pictures of clouds, I'd have forgotted what they look like
:-P

Anyway, looking at the model forecasts for tomorrow, there'll be a broad
trough over Vic/NSW with the AVN model going for CAPE of around 500J/kg
near Echuca, but with surface RH ~20-30%. As I'm pretty desperate for some
action, I'm thinking of heading up that way tomorrow. What do other people
think? Waste of time/money?

I'll check by here again tomorrow morning (provided I get some sleep soon)
to see what's happening.


Cheers

You are correct, Andrew.  Theory is that they do not have at least
*appreciable* nor visible cloud base rotation.  Thus, nor are they attended
by a funnel aloft.  The "gustnado" is made visible only by a surface dust
or debris whirl.  Non supercellular tornadoes that do have cloud based
rotation are called either "non supercell tornadoes" or "land-spouts". 
(Some write this as one word, others as two or still others as I have

This Line was still really good when it arrived here at Gosford, I was 
trying to capture these really close CG's with my camera when one 
of them hit a transformer a few suburbs away, it exploded and 
made all these fizzing noises and I could see it on fire!  All the lights 
went off in that suburb, then another one hit close and all the power 
went out here for about 2 hours.

Replying to my original email, with the updated AVN forecast going for
CAPE less than 300, and with a 300+km drive to get there, even I have my
limits. Looks like I'll be watching any action from the comfort of my

Hi all - seems that there is a rare SE Pacific TC atm - not real strong but
evidence of the strength of the MJO pulse that went through.

Anyone got an idea how likely TC's are in the SE Pacific? I always thought
they were rare......

Re TC Rita - quite rare that far east. Usually more common in el-nino years.

However, I have always found it very difficult to get any accurate
up-to-date advisories in this part of the world. I notice that Fiji Met has
improved considerable in that regard this year.

It appears that we are almost full cycle with latest 'west to east' burst of
monsoonal activity. Clusters of storms are starting to becoming more
apparent again closer to Africa/Madagascar.

That would suggest another monsoonal burst over Australia mid-to- late March
if the cycle repeats.

Regards
Simon

<snip>

Whilst they are considered rare, this is the 2nd SE Pacific TC of the
season - the previous one was TC OMA 08F 11P around the 30th 21st of Feb.

The activity of this MJO pulse can be seen more clearly in the FMS area
marine bulletin from http://www.met.gov.fj/aifs_prods/10140.txt  pasted

Simon,

Looks like this is a mid to upper level feature possibly responding to
an increase in the jet which heads NE in the direction of / in response
to TC Paula (12P).  It is located at the northern edge of a 300hPa
trough.  What is very interesting is that it seems to have been
'anchored' in the one spot for the past 12 hours!!

Hi

Got some photos back, and wrote up a little report on the squall line
that hit sydney on Feb 28.
http://www.sydneystormchaser.com/2001/February28.htm

Also a report for the Jan 17 storm chase is up, some people would have
seen this already.

Hi all,

Possibly also to do with a high being present over the area, helping to
split/divert the jetstream further north over that section, enhancing a
300mb upper trough that will most probably descend down through the
layers in the next 24hrs.  Might even see a surface low develop early
next week from it - is it just me, or does that look surprisingly
familiar to what happened a couple of weeks ago?  We had an upper level
trough amplifying in the Tasman with the help of a nice Quidge.  The
Quidge got killed by a surface and upper low that developed and moved
westward.  Approximately 6-12hrs before the main development of the
cutoff low itself, we saw a huge arc on the jet reaching will into the
tropics of QLD.  This was enhanced on sat pics due to ex-TC Wylva being
in WA.  Here were are 2 weeks
