Hi people,

My name is Max, I've just subscribed to the mailing list, and it makes
interesting reading.
Just thought you might like to know, I was standing out near the old Control
tower at Mascot Airport
somewhere between 8.30 and 9.30pm, and i saw a HUGE flash of lightning way off
to the South.
That may well have been the same one......
Incidentally, can anyone tell me what IRC channel you folk in Sydney use....
thanks.

Hi Max

There have been a number of small cells moving north westish well out to
sea, so you would have seen a flash from one of those, anyway id like to
welcome you to the list and could you tell us a bit about yourself ?
name/where you come from/weather interests etc.

We hang out on the channel #weather on the austnet server on IRC, theres
usually a couple of people there all day and 1/2 the night :)
Might see you there.

Minutes for May's WA ASWA meeting

Meeting started at 5:30pm

Attendees: Ira Fehlberg, Greg Spencer, Mike Fewings, Rebekah Hoare,
 Mark Dwyer, Jacob Aufdemkampe.

No Business was brought forward from last meeting except the issue of those
who haven't yet paid their memberships.

Barry Hanstrum from the WA BOM will be attending our next meeting, so we
discussed what we want in terms of the relationship between ASWA and the
BOM here in WA. These points will be put to Barry at our next meeting.

Points raised were:

Recognition that we are an association.
*The wish for our reports to be taken seriously in the wake of the Sydney
Hailstorm issue.
We all agreed that we wouldn't be phoning the BOM with inappropriate
information, however if two or more of us conferred and agreed a warning or
forecast has been over looked than a phone call would be made with us
identifying ourselves as ASWA members.

Damage assessment program.
*We want to offer our time to help the BOM with accurate reporting of storm
damage, as the do not have the manpower to always do this.

Storm Spotters Re-vamp.
*The storm spotters program has been quite for a long time over here and we
would like to see a re-vamp of the program even if this involves us taking
some of the workload ourselves.

At this stage of the evening we took a break to watch "Savage Skies" on
channel 9 featuring tornadoes and lightning.

Resuming the meeting Rebekah brought forward a good point about the
information, or lack of, for those interested in the weather but don't have
a great knowledge of it but wish to learn more. Several members' homepages
contain this info but we all felt that ASWA needs to have something like
this available at the ASWA site. For the average person visiting the site
there really isn't any information about weather patterns, storms or
tornadoes in Australia. The point was also made that this information is
state specific. Most states have their own sites but we all fell that this
information needs to be integrated into the ASWA site. Greg, Jacob and
myself agreed to put together a WA wing of the ASWA site.

Another point was made by Mike about the storm report page on the ASWA. It
was suggested and agreed by all that it is very big and difficult to fill
out. Whilst it is an excellent idea that should remain, all agreed that
they may not fill it out after every event due to the time it takes. It was
suggested that maybe a simpler version could be made?
We also wondered where the information is going to and where it is to be
used? All agreed that they would be more likely to fill out such forms if
the information was put together and made visible at the ASWA site.

We also discussed the possibility of social evenings or days out for
members to get together outside of weather issues. All agreed that we would
hook up to go and see the new Star Wars movie.

Meeting closed at 9:30pm

Hello Everyone

A report on commercial television last night, from the Cruising Yacht Club(?) in a sailing magazine, blaming the crews of the yachts in the Sydney to Hobart for the trouble they got into. It also stated that there were inaccuracies in the met reports and they were critical of the way met reports were issued.
Has anybody read the magazine article?
It looks to me in the preliminary  Met report that the BOM released its forecasts accurately and with plenty of warning time. I am sure there are not too many of us who would go to sea heading into a area of gale and storm warnings!

I seem to recall reading somewhere that the relative contribution of
(a) and (b) was around 90%, and (c) around 10% - this would presumably
depend a fair bit on the relative wind speeds vis-a-vis central 
pressure and the configuration of the coastline.

The North Sea is unusually vulnerable to this - there aren't many
places in the higher latitudes where there is a flat coastline 
exposed to the west or north (contrast with, for example, Norway,
Oregon/Washington/British Columbia, Chile and New Zealand - all highly
mountainous). Worth noting here is that, despite what the Anglo-
centric media of the time would have presumably emphasised, the 1953
event caused far more damage and loss of life in Holland than it did
in Britain. There was also a major coastal flooding event in northern
Germany/western Denmark in January 1976, although I think loss of life
was minimal - these areas are no stranger to coastal flooding and most
settlements are well inland.

I've also seen substantial (~2 m) storm surges in Port Phillip Bay 
during an episode of prolonged gale- to storm-force W/SW winds in
November 1994. I'd imagine that, given the configuration of the coast,
Spencer Gulf (and to a lesser extent St. Vincent, although Kangaroo
Island would provide some level of protection) could be vulnerable to
a storm surge in the right sort of winter S/SW flow (say, with a deep
cutoff centred east of Adelaide) - can any SA readers remember this
happening?

Germany and Switzerland, in particular, get their share of thudnerstorms
from my experience (in late August-early September 1994 I experienced
seven separate thunderstorms in 48 hours near St. Moritz); one would
imagine the risk would remain as one went further east. Scandinavia
can also get severe storms - there was a damaging tornado in Gavle
(Sweden) in July 1994, and I saw one of the more impressive hailstorms
of my experience (not being from Sydney, this means the stones were
topping out at 2-3 cm) south of Trondheim (Norway) last August.

This one's actually vaguely defensible on rainfall grounds - Bowral is
far enough east to get much of its rain from the east, unlike locations
further west in the Southern Highlands. (The same logic applies to
locations like Braidwood and Nerriga, which are classified in South
Coast). Of course, once one extends to elements other than rain, the
district boundaries are very dicey.

As previously remarked, district boundaries are essentially set in
stone - I get the distinct impression it would be bureaucratically
easier to move Bowral brick by brick to a location in district 70 
than it would be to change the boundaries to include Bowral in that
district!

Aus-wx colleagues! Time for another thread:-) Just think
that without old Sol and our fortunate orbital position,
we live and have reasonable weather for living because;

1) Unlike many recently discovered planetary systems, we
don't have huge gaseous giants close in to mop up all those
nice Class-M (Earth-like) planets.

2) Sol is comparatively stable and long-lived. That's a
fine recipe for the evolution of Life On Earth.

3) Earth's orbit is remarkably stable in that it is not
too elliptical.

4) Rotating every 24hrs or so is just nice for our
position in space to allow our weather cycles (based
on H2O) not to become too extreme. Just think of the
consequences if this was a week. Those "cycles" would
be more extreme, I think:-)

5) Earth's axis of tilt is also not too extreme. Just think
what it would be like if we rolled around our orbit like
Neptune (?).

6) Our mixture of atmospheric gases is about right provided
we don't overdo those greenhouse ones and cook like Venus.
We had a horrible mixture in early days that seems to be
the right mixture for carbon-based basic building blocks 
of life. Evidence has mounted supporting the notion that
life itself has played a critical part to derive the final 
mixture of atmospheric gases.

7) Take awat Sol and we'd become a lovely icy planet.

It seems to me that astronomical influences are fact and
never open to debate. Now as to precisely what astronomical
perturbations have in stall for us? That is an issue open
to much research and potential constructive debate.

As some of you may be aware, the radar password changed this

If by chance you still have authorization fail you will need
to either go through the ASWA Inc. site at

http://www.severeweather.asn.au/members/membersarena/

or if you have that page open already, reload it while
keeping your finger firmly pressed of the shift key on your

If both of these things fail you can contact me at

Can anyone help me with a max/min thermometer problem.

The marker keeps sliding down on the maximum side, so it is hard to get
an accurate reading. It's one of those push button ones, that you reset
daily. When I turn it upside down and let the markers "Drain" to the top
of the thermometer and then release them, it seems to help somewhat but
the problem seems to persist. What is the process involved in these
thermometers? How do they work?

Does anyone know of places that I can purchase a moderately priced
max/min thermometer if this one ends up being stuffed?

Also, apologies if I haven't got back to anyone that has emailed me. As
I said, I've been out of action for two weeks.

Hi Glenda,

I used to live on the South side of a wet & cold gully at Hornsby in a 
dense Bush situation - no sun in winter lots of damp, moss & mould.  In 
fact, after rain, it was not uncommon to find Leaches on the back deck, the 
boards of which would rot through in around 2 years.  I found that I had 
huge problems with Hard Disk drives - they really object to condensing 
atmospheres and irregular use.  I literally have a carton full of dead hard 
drives spanning every major manufacturer - none of which lasted longer than 
18 months.  Mode of failure was always difficulty booting up the drive 
followed by spin down after a gradually shortening period of time - 
eventually the disks dying altogether.  I figured it was the damp getting 
into the drive electronics but how this leads to permanent failure is still 
a mystery.

Computers like to be kept warm (10C...35C) & dry (non-condensing 
atmosphere), or simply left switched on,  where the internally generated 
heat & airflow will do the trick.

Just to keep this weather related... Brisbane is a great place for 
computers (and living...), although the weather at this time of year 
becomes something of a dry topic :).  Current situation Fine, 1/8 cloud 
cover, Gentle SW wind, temp around 22C.

John.

Hi Lindsay,

The sliders are made of a magnetic material.  A small magnet or magnetic 
strip is attached to the button, such that it adds sufficient friction to 
slider movement to stop them from falling.  When you push in the button the 
strip is pushed away and the sliders can move more easily.

This whole mechanism is not very robust and rather delicately balanced. 
 Vibration or poor construction can result in the sliders moving when they 
shouldn't - or worse, not moving when they should, resulting in them 
drowning in the Mercury column (Very difficult to fix).

I have tried several of the cheaper variety (after having first calibrated 
them against a digital thermometer for accuracy - most of them are anything 
up to a couple of degrees out) and typically the min column reading does 
not exactly match the max column reading at any given temperature - again 
highlighting their inaccuracy.

Better quality max/min thermometers use the opposite approach.  You have 
small hand held magnet to drag the sliders down to reset them.  These days 
I think a digital electronic thermometer with outside sensor is probably 
the way to go if you can afford it - I'd be curious as to what the BoM 
thinks of this.

John.

I've just updated my website to carry noteworthy weather observations.

These are available in near real-time from my Bureau of Meteorology
data feed. There's also a one-week archive, but right now it only goes
back to last Wednesday. 

The data is updated hourly at about 20 minutes past the hour, and is
in two reports:

Synoptic observations are the 3-hourly reports that come in from the
Bureau's Australian synoptic network. Any observation which shows
significant weather (defined in the heading of the report) will appear
here -- heavy rain, strong winds, noteworthy weather (like
thunderstorms or snow), or abnormally high/low temperatures or rapid
barometer changes.

AWS observations come in hourly or half hourly, and more often when
significant weather conditions occur. An obs will appear here if the
wind gusts to 45 knots or more, or there is 1.0mm or more of rain in
the past 10 minutes.

I'd strongly suggest you read the "important information" link, even
if you can figure out what you're looking at on the reports. 

I hope everyone on the list finds these useful. They should get often
unobtainable but relevant data into your hands as events are
occurring, with a short archive to help you download the data to study
at your liesure. 

It's taken nearly 3 months working with the Bureau to ascertain
whether distribution of the data like this complies with the Bureau's
still-uncertain secondary distribution policy. All I can say is that I
believe that it does at present, but things will hopefully be
clarified soon. The Bureau is holding a meeting with commercial
providers, to which I've been invited, on 10 June to discuss these
issues, so more should be known then. Any comments you have on the
usefulness of this sort of data would be appreciated by me, too, as I
may have to make a case for its retention.

I've also written a fairly lengthy briefing article for Australian
Weather News on the current state of play in the Bureau's data access
policy -- worth reading if you were interested in the recent thread on
this list about this.

For now, enjoy! (Always subject to my computer not spitting the dummy
;-)

 Any questions?  Just reply to this thread.

Thanks a squillion, Laurier. I'm running out of bookmark space.

On the subject of access to BoM data etc. Not only would I
mind being involved somehow as the voluntary ASWA archiver
of satpics and radar (I can say that now:-) but I'd also
like to see all BoM data as freely open as possible. Of 
priority interest is BoM model data (LAPS, MesoLAPS, GASP)
and HI-res satpics (~4km). Access to these might prevent 
my venturing to US model sites (NOGAPS, MRF, AVN) as prime 
model data source and NPMOC for gmsd and gmsc satpics. I'm
all into "Buy Australian" provided it offers superior value.

The Bureau of Meteorology uses separate maximum and minimum thermometers.
The Maximums thermometers are mercury in glass with a small constriction
that breaks when the temperature falls (just like a medical thermometer).

The minimum thermometers are alcohol in glass with an index that is dragged
down to indicate the lowest temperature.  

The cost of these thermometers are well over $100 each and meet an
Australian Standard for meteorological thermometers.

Thermometers are located in a Stevenson Screen designed to shade the
thermometer from direct and reflected sunshine, but allow a free flow of
air through the screen so that the thermometers can measure air temperature.

The thermometer you are talking about is a Six's pattern thermometer
designed by a Mr J Six.  As has been previously mentioned they are not as
accurate as the individual thermometers.

In addition to glass thermometers that need to be read by humans the BOM
uses platinum resistance thermometers in automatic weather stations.

I think that this might mean;

1) Only bash the BoM and/or media when facts confirm first:-)
2) A decision is required as to "who" awards;
   a) The BoM, for excellence in weather advice to the media
   b) The media, for excellence in reporting such advice.
3) "who" needs to be independant of the BoM and media.

Cheers,

Michael Scollay       mailto:michael.scollay at telstra.com.au

P.S. Above all, the "list" besides being an open forum, must strive
to remain constructive when it comes to progress forward in regard
to the study, observation and understanding of aussie-weather.

Hmmm Michael,

How do you define "Winter clouds"??

A winter cloud in QLD might well look like a summer cloud in Victoria... 
 And to not discriminate against members who don't live in the Antarctic 
regions of Australia :) surely the definition should be any cloud photo 
taken in Winter (ah but how do you then prove that???)

At our last ASWA meeting we had talked about requiring photo's to have been 
taken in the same month (but any year) as the month of the competition - 
and then using the winners in an annual 12 month "ASWA" calendar (which 
could also be a revenue source).  Anthony - were these suggestions ever 
forwarded??

Now, onto the June selections, would I perhaps dare to suggest that just a 
tincy bit of colour enhancement may have been added curtesy paintshop pro 
or some similar tool??  Is this fair game?  Me thinks that after voting is 
complete, winners should be required to make an original print available so 
that the judges can then ensure that it is a reasonably close approximation 
to the colours in the photo as submitted.  (thinks - what if it is from a 
digital camera??).  Any photos which clearly have been "enhanced" should be 
dumped in the "Dungeon of Disgrace".

John W.
>snip

Submissions are now open for the July photo competition.

July's theme is "Winter Clouds."

Hi Ira and WA members as well as the rest of the list,


Jimmy here.

I think the point raised in the WA meeting about filling in the storm
report is a valid one. I have brought it up a couple of times here in the
NSW meeting. My suggestion was to actually give someone the job of taking
charge of the page. They will research and manually fill in that page any
storm reports that came over the list and then this makes sure that is
actually entered. The person or persons has to be one who is willing to do
this and is always subscribed to the list and checks in daily.

What do people think? Is this a reasonable idea or are there other ideas. I
think the problem has to be solved by the next season. We can also simplify
the page somewhat but I don't think that the problem will be fully solved.
Sometimes, information comes in bits and pieces and someone can then make
the entries....

Come one, any ideas and are there anyone who would like to volunteer for
the job?

Jimmy Deguara

Hi Les and everyone else :),

I just thought I'd relate my storm experiences, at least, what I can recall 
of them, both in England from 1980-83 and in Europe during 1993

I can recall quite a few decent storms in England, specifically Lincoln, 
during the early 80s. I can't remember any news about the 1981 tornado 
outbreak unfortunately. The southerly wind in England is very humid - coming 
from a mix of the heat in Spain as well as the moistness from the warm water 
that reaches the SW coast areas. I can remember some spectacular storms - 
including one where the sky was an orange colour - due to the pollution on 
doubt - but it was truly spectacular.

I also saw some awesome storms in the Dordogne regoin of France ( have a few 
photos) and several spectacular night-time ones in southern Germany. 
although the air temps never got above 28-30C, the humidity would've been 
around 60% or so on both occasions. One of the southern Germany storms was a 
t night and was spectacular - lightning every 2 seconds or so.

I'm surprised that we do not hear more from Europe in their summer months - 
conditions can be very favourable for severe storms, plenty of temperature 
contrasts in the area, some useful DP's occasionally as well as a couple of 
major mountain ranges - and in high summer there is easily enough solar 
heating on many days - even in England - no offence :)

As of last Friday morning it was 69.2 mm. Although I haven't calculated
the index exactly since then, looking at the current trend it would be
about 72 as of this morning.
Bear in mind that the index is highly subjective as it is a function of
the annual rainfall and daily maximum temperatures of the site at which
it is measured.
If you have a list of your maximum temperatures (or Wollongong's,
assuming they would be almost identical) plus the daily rainfall since
the last time you had floods (which would have dropped the index to
zero), I could work out the index for your location or if you have a
spreadsheet program I could send you the equation (or the Excel 97 macro
I use to do the job).

As to the negative feedback side of things, one has also to remember
that the oceans are an enormous sink for carbon dioxide and from what I
have read, the oceans appear to be more capable of absorbing CO2 than
was first thought. I haven't heard of oceanic absorption of ions..I
would think that sunspots, being cooler, would emit less radiation,
depending on the type (ie long or short wave).I think the cooler the
temperature, the longer the wavelength. Someone out there with much more
knowledge of physics than I will no doubt be able to clarify that
one.But whatever wavelengths are emitted, the question is, how do they
affect the ionisation? Sea water of course also contains many other
elements particularly bromine and iodine but a halogen is a halogen and
very interactive at that, at least chemically!
Although I don't subscribe for one second to this New Age 'Gaia' rubbish
we hear about sometimes (ie the earth is a living, breathing organism or
something like that), there is no doubt about earth/sea/astronomical
interactions which make up the weather and much more research is
required before the doomsayers can be taken seriously.I don't mean we
should ignore warnings to cut emissions, we certainly need to have
measures in place, but we shouldn't believe everything they say just
because they are scientists and think the rest of us mere mortals are
too dumb to question them.

I haven't seen a push button one Lindsay but with the BoM standard one I
use (it's like a giant doctor's thermometer you shake down every day) I
mount it almost horizontally (in a Stevenson screen), the bulb slightly
lower than the other end. You might minimise the slipping marker if you
can do this with your one.
Hope this helps...

Some reports are trying to paint this tragedy as another Sydney Hailstorm type blunder, but there is a world of difference. Many of the yacht people knew what they were getting into, so it is like surfers complaining about a mate drowning at a surfing contest at sunset beach because the forecast said 20ft seas instead of the 30ft that occurred.

The wealthier crews would have had access to the US models like the rest of us, I would imagine that they would have known exactly what was going down and plotted courses still to win the race, not to turn back because of any risk.

Another factor is these boats are designed for speed not toughness, sort of a race car compared to a 4WD , except the sailing suddenly became 4WD territory so to speak.

Hello Everyone

A report on commercial television last night, from the Cruising Yacht Club(?) in a sailing magazine, blaming the crews of the yachts in the Sydney to Hobart for the trouble they got into. It also stated that there were inaccuracies in the met reports and they were critical of the way met reports were issued.
Has anybody read the magazine article?
It looks to me in the preliminary  Met report that the BOM released its forecasts accurately and with plenty of warning time. I am sure there are not too many of us who would go to sea heading into a area of gale and storm warnings!

The balance thing you talk about is true, afterall everything strives
towards balance, the balancing of heat is what drives weather afterall. I
know where your argument is coming from, and to an extent increased CO2 even
helps plants grow better, that sort of thing. But that is as far I would
agree with your arguments.  But the earth's attempts to ' balance ' things
may not occur in nice peaceful scenarios, what if increased absorption of
Co2 into the ocean led to a major ocean current changing course, what if the
gulf stream decided to just loop the mid atlantic. The older I get the more
I think that no climate change happens gradually or peacefully, and triggers
occur far more frequently than we realise, so why push our luck any further.

Man's reliable history into major climate events is perhaps at best 2000
years old, on an earth scale that is nothing.

On a slightly more borderline issue does anybody believe that the periodic
switch of magnetic poles is a relatively harmless thing, or does it unleash
volcanic chaos and subsequent climate change.

A pity as I do not keep temps and rainfall any longer, it's those trees
again, the figures for my yard are just too unreliable.

No good using Wollongong as the site is near the escarpment and has had
20-30mm more than me over the past few weeks.

Except that there are precedents for climatic change such as the one
that changed the climate of Greenland from a habitable place (it used to
be green hence the name) to a place so cold the residents had to
leave.This was over 150 years. I agree with you Michael that there is
potential for man, in his stupidity, to stuff things up pretty quickly
but I think the 'balancing' would limit that and indeed, has done so
far,as witness the fact that the scientific community is almost
unanimous in saying that we need a lot more research etc before we can
conclude that man's CO2 (and the cows' CH4) is causing our climate to
change that rapidly.
I know CO2 emissions weren't around in Leif Ericssons's time when that
climate change happened but the means of 'automatic correction'
certainly were and I see no evidence of that having diminished.
What I am trying to say here is, what sort of triggers could trigger
such a catastrophe that, for example, the sea level would rise 3 feet in
say 50 or so years? And yet that is what some of the extremists are
trying to make us believe.
As I have said before, we let these people scare us with as yet unproved
theories. We sit and let them tell us what to do, what to say and how to
say it.And then when someone says something like that, they are
immediately put down and laughed out of town.
The real balance needs to be (1) in what precautions we take given the
limited knowledge we already possess and (2) filtering the dogmas of the
scientific community through demanding they publicly justify their
position rather than let them (with the help of the media) promulgate
theory as proven fact when it isn't (a bit like evolution, but this is
not the forum for that one).
To get this back to something meteorological,I wouldn't mind a warmer,
wetter climate in Sydney...and (referring to another thread), what could
be a more wintry cloudscape than Sydney in a westerly gale under a
standing lee wave or those cold freezing southerlies that bring all the
low cloud up but scarcely any rain?

Well not me, but my car. Washed it for the first time since April 14 on the
weekend, and there are several on the bonnet. Only small but they are there.
My wife had the car that evening at Shellharbour where golfball size hail
fell.

I would not mind that warmer and wetter climate also.

You have a point in that most of this involves personal barrows being
pushed.

Any reasonable trust seems to have gone out of any discussions in the last
20 years, whether they be financial, scientific or political. Everything is
a negotiation these days, in other words to get X you have to present a
scenario of X+y. So if your a scientist who earns a living from the study of
climate you have to convince the government to fund you, on the other hand
if your a environment officer for a oil company, well everything is dandy
and climate change is all theory.

I'm in one of those sell everything and go live on a small farm, feed the
chooks and grow the vegetables moods at the moment.

Hi all,

There was a comment about people changing the colours of photos
that have been submitted and I was just wondering which photos
people were referring to. I've just checked out this months photos
(http://www.severeweather.asn.au/photo/) and I can't see anything
too strange. I trashed the email that mentioned this problem so
I can't reply directly - but I think photographers should be given
the benifit of the doubt, since there really can be some spectacular
lighting effects that only *seem* to have been colourised (and in
fact in many cases the offending pic may in fact be a poor imitation
of what actually was occuring in the sky)

cheers,
Chris

Unfortunately, weather isn't the only area of life where commercial
decisions come into play.  The minute money becomes a factor, the whole ball
game changes.  Justifications are required, grants must be applied for,
funding becomes an issue.  It is unfortunately a fact of life, and one that
none of us will ever be able to change, however much we dislike its role.

I doubt that it was referring to any of the photos displayed. I assumed that
it was a sensible general rule that was put ' before ' anybody tried this

As Laurier Williams stated earlier the BOM Gopher site has closed after 5 years of operation. This is very depressing, where am I going to get my 2 and 3 day NMC GASP Forecast charts from now? Where am I going to get my current Victorian observations (updated every ten minutes or so and including stations right across Victoria and southern NSW) from? Oh well that's progress I suppose. 			As for the first day of winter in Melbourne what can you say, a little early drizzle cleared to a cool overcast (Strato-Cu) day with a moderate west to northwest wind. 8/8 Strato-Cu all day great for all you eager Sc chasers. Top temp in the city 15.4c and here in Kilsyth the top was 13.6c, all in all a pretty typical early winters day in Melbourne. And to think only 3 more months of this to go. The outlook for the next few days looks pretty exciting a few late showers tomorrow( Wednesday) and then mostly fine and cool right through into early next week, top temps around 15 or 16 each day Bliss!!!. Dane.
