Hi all
Myself and Paul Graham were suckered by the severe storm warning and some
beautiful towers right across Sydney (+ surface temps over 40 in the west
and DPs near 20) and decided on a chase . Due to my work commitments, we
didn't get started until around 4:00pm and so the Hunter (the preferred
target today) was out of the question. The Sydney storm for which the
warning was issued was structurally unimpressive - very high based, albeit
with a nice rain curtain at one stage, but the type that is likely to give
dry microbursts IMO. Indeed strong winds were the BoMs main concern with
this one although due to reports of small hail in the southern suburbs the
advisory included 'may produce large hail etc'. Anyway with these storms
riding on the front (which arrived in southern Sydney sometime around
5:00pm) we thought it best to head a little north and up to Wyong.
Unfortunately there seemed to be a mighty cap and nothing really got going
despite there being some of the most spectacular towering cumulus I have
seen for a long time. The highlight of the day was a quite bright AG (air to
ground) bolt, perhaps 10km from us. This 'CG' dropped from an innocuous
looking cumulus, not a tower but a real little cumulus. There was a storm
further east but this definitely wasn't associated with it. It was the most
unusual thing I have ever seen and I think ditto for Paul. Perhaps others on
the list may have witnessed something similar before. The only reason we
were looking at such a boring cloud was that it was in the direction we were
heading.
Oh, Jimmy has checked in for the night at Urunga and hopefully for him there
will be some destabilisation of the lower atmosphere and he should see some
nice storms tomorrow (today now), despite the winds looking a bit
pedestrian.

Ok the last thing i wanted to read at 1 am in the morning after i got back
from a hard days chase was everyone arguing/disagreeing about certain
topics, and i am in no condition to comment on those.. so i wont.. (i am
absolutly stuffed).
here is a very very brief rundown on the chase conducted by James Harris
and myself.
Castellanus observed ALL day. from morning right through to 10pm at night.
Development highly capped, everything that developed was high based, not
just that cell in sydney the other guys talked about, i mean everything in
the hunter as well. Saw some textbook storm from the US.. supercellular in
appearance.. great stuff, as we got closer it died and we made the decision
to turn around and head back to the muswellbrook (spelling) area. We saw
the only storm all day we had seen with any nice amount of precip comming
out of it SW of singelton, so we headed for it. A gigantic RFB developed,
and we drove under it, whilst watching the precip we had seen earlier kick
up dust ahead of it, which fed into ANOTHER updraught at the front, amazing
stuff to watch. By then the RFB decided to drop its load on us, right when
we were underneath it. Torrential rain, and strong winds accompanied it.
When we arrived in Singleton the hail started, we both got some nice
footage of hail around 5c piece size falling, bouncing here and there etc.
We had to go out of this storm and travel more SE then back north (road
networks suck sometimes dont they ?:) to catch the cell, we never really
caught it again, but we saw some lighting at sunset from it, and a
spectacular sunset, anvils being sunlit, Tcu being sunlite, the best
mammatus i have ever seen being sunlite and changing colours etc. (im sure
others have seen better stuff, but its the best ive seen!). And then it
started, the lightning show (we were at Dungog) BEAUTIFUL isolated cells
being fully lite up by CC/CG lightning every 2 seconds or so... GOOD GOD if
SOME of those photos me and james took come out, they will spectacular.
(out of cloud strikes etc etc)
Anyway thats it, i will write a report tomorrow before work
Thanks to these people for helping us out with updates:
Anthony, Ben Quinn, Daniel weatherhead, Paul Mossman and Jane ONeill. Im
pretty sure thats it, thanks alot for your help, esp. to anthony/ben for
the updates on movement on the singelton storm, continuing to go after it
and get that lightinng show paid off big time! Apologies as well for when
the phone cut out of service and my battery finally went dead..not to worry
though.
This email is suddenly alot longer than what i had planned for a briefing!
hehe
Bed Time.
Matt Smith

If, indeed, we did have a dew point of these extreme values as quoted.....I
believe that the the vapor pressure of the water vapor would rival the
atmospheric pressure! We could come close to doubling the current
pressure! I have not put a pencil to this but I believe this would be
true!

BTW......I hate to admit that this came from the US.......but you might
look up this site and see how this strikes you!!! These statements were

from knowing the limits of forecasting!

I guess I am guilty of bringing in far too much US weather. Yes, you are
right, this is Aussie Wx and not others weather.

Chase Details - 19 January 2000
After my afternoon reports of some decent storms around Newcastle, most went
just south of Newcastle, Belmont maybe or well North, perhaps north of
Nelson Bay.
The northerly storms looked impressive from a distance but I couldn't say
anymore about them.
The other storms would build to the SW and then move just south of Newcastle
and out over the sea. Perhaps the most spectacular parts of the evening was
watching the colour of the storms change as the sun set. The base of the
storms would be a rich blue or velvet whilst the colours would mix into a
pink, orange, yellow and then bright white towards the top of the storm.
The first cell I watched didn't get organised until it was out to sea. It
stuffed around, dropped a bit of rain, one decent hail shaft, had a cough
and splutter with thunder until displaying some beautiful mammatus once it
crossed the coast line.
The second cell I watched from a inconspicuous turkey tower and grow into an
impressive storm. The anvil had some amazing convection moving up the side.
The lightning show was good to watch although no decent rain was noted.
This was the storm that the sun painted the colours of the rainbow.
Both storms I watched had low inflow winds, barely more than a breeze, but
inflow nonetheless. After the 2nd storm, another turkey tower tried to get
going but died a quiet death without even a drop of rain.
Overall, two goods storms watched from a northerly position.
Distance travelled: 10 metres. (Good value for money)

G'day!
Yeh? Earlier there had been low scud cloud rolling in due to a very moist
Northerly blowing off Bass Strait which obstructed the view of most of the
sky. Then later the wind shifted to the NW and the low stuff cleared
revealing the growing towering Cu that rapidly grew into a text book Cb with
a lovely Anvil! As the storm moved towards the East Coast, smaller cells
grew in it's wake. But I never kept track of what happened later, so that's
interesting to know.

Leslie,
I didn't mean you specifically when I mentioned this was the Aussie weather list, it has been very educational reading
the information you put forward to the list, and I know there are a lot of similarities with the weather you experience
there and our weather.
Perhaps I was a bit harsh in making that comment, but I do believe the list does lose track sometimes......
Again, sorry if I upset people, just wanted to express my opinion.
Andrew.

Hi Les,
Yes well, I think I disagree with the sentiment. I like to hear about
severe wx from anywhere, and I think it is good to compare overseas events
to the aussie experience which helps put it all in context. In particular,
I think your contribution has been invaluable to date.
This is a public list where folks are free to share their opinions. Of
course from time to time there will be adverse commentary or even the odd
bucketing, right or wrong. That is to be expected and no-one should feel
they are immune from this. The important thing is to have enough maturity
to not get emotional about it.
John.

I guess I am guilty of bringing in far too much US weather. Yes, you are
right, this is Aussie Wx and not others weather.

Hi All,
Looks like Brissy is in for the first seriously warm day of the summer. Mt.
Crosby temp at 7:30am already nudging 28C after min 22C (Yesterday 34C).
The dreaded NW'ter is strong with 0/8 cloud cover. Reckon it will reach
high 30's maybe 40C here.

I think that discussing weather, whether
its aussie, the states or the UK or anywhere else is all valuable because of
the research that has been done to varying degrees in different parts of the
world.
We have also discovered that the setups are as different in Australia state
by state (look at the CAPE required to produce severe wx in WA as compared
to Qld!!! ) as they are in the rest of the world....keep it up - let's keep
learning and discussing as we have always done.

That's right, this IS a public list where people can share their opinions, so why does everyone get annoyed when others
air their opinions?
If you are not one of the list "gurus" you get laughed at or ignored, you do not have to chase thousands of kilometres
to understand storms, on a typical summer in Sudney, they pretty much come to you!
I cannot believe that no one else on this list thinks Halden got a raw deal..perhaps you are all too afraid to speak
up, for fear of being persecuted yourself?
Oh well, this list sucks now!
Have fun.

Hi John,
Indeed my A/C will get (its first) workout :)
8:10am Belmont temp, 31.3C with a DP of 23C. Min of 24.2C though
(surpisingly warmer than Mt Crosby). Maybe it's safe to say summer has
finally arrived? Just that whenever I say it, we get another blasted
ridge for 2 weeks over us!

Hi John,
you are most correct. I guess it has been 3 years since i have had to recall
any EM stuff - a magnetic field from a alternating current of what, mA? I
deserve a good whack from a thick physics book! BTW, i realised when i
quoted EMF that it would be confusing to somone who knows what
Electro-Motive force is, but i figured i was going to have to say EM field
so much that EMF would suffice ;)
Curious, i've never heard that the dissepation of charge is the source of
the field that shocks people - interesting.
Cheers,
Lyle

Subject: RE: aus-wx: fluro's and lightning
Hi Lyle,
I seem to recall that a flouro works via current flowing through the (low
pressure ionised) gas, which produces UV radiation. This interacts with the
phospher coating on the inside of the tube which flouresces to produce
visible light - hence the word flourescent lamp.
When a lamp is off, the gas is not ionised and is basically non-conducting.
The starter circuit ionises the gas by switching on a heating filament at
the end of the tube which releases metal ions, plus the ballast (inductor)
is used to produce a high voltage kick to break the gas down. Once the lamp
has started, the gas remains ionised by virtue of the AC current flow and
the heating filaments are switched off. I can't quite remember the purpose
of the Capacitor, it may be to protect the starter switch from arcing, or
simply to correct the powerfactor load of the ballast.
If you can supply a flouro with a high enough voltage (several KV) this will
also ionise the gas, and hence allow current to flow. And as previously
mentioned, only a very small current is required to generate a visible
result.
The magnetic component of the EM field around HT powerlines is basically
insignificant, but the electric field is substantial, being many KV per
meter between the line and ground. So the action on a flouro near HT
powerlines is purely due to electric field. You prove this by changing the
orientation of the tube, it only lights up when pointed at the lines, it
does not light up when oriented in any parallel plane to the lines. (Which
would be the case if your EM radiation theory was correct).
Lightning produces copious amounts of EM radiation, as is evidenced by the
crackles on radio. However, this is only instantaneous with the lightning.
I was picking up on the comment that the tubes glowed for a second
immediately AFTER the lightning.
So, I was suggesting that the CG transferred a large quantity of charge,
which appeared almost instantaneously in the ground at the location of the
CG. This must produce an electric field in the ground, which will quickly
decay as the charge leaks away. How quickly will depend upon the
conductivity of the ground. (It is this electric field near lightning
strikes which is responsible for most shocks due to lightning).
Seeing as Miguel was in a basement at ground level, it is not difficult to
imagine that the fluoro's and in particular the wires leading to it, were
subjected to the electric field with the consequent result.
Regards,
John.
p.s., the term EMF conventionally is short for Electro-Motive Force,
referring to the induced voltage in a conductor subject to a changing
magnetic field or moving through a magnetic field (the same thing
relatively).
>snip
G'day John,
I'm not so sure this is fully correct. You'r saying that the glow is due to
a small current but that doesn't give the link to the lightning bolt.
Lets use your example of the HT lines. Lets say it's suspended by a
non-conductive material, so there is no direct source for current. The fluro
will still glow. This is due to the voltage induced by the changing EM field
which excites the atoms to relase photons in the visible range (you could do
a calculation here to quanitfy the required voltage, but it would be well
documented). The low power requirments is because not much energy is
required to eject a photon by voltage induced excitation - the main power
sink is charging the capacitor to get the fluro going in the first place. A
convential light source produces the photons via thermal excitation,
requiring a continual feed of power, at a higher rate, so to raise and
maintain the tempreture of the fillament.
BTW: Fluro's lighiting up in strong EMF fields would be very normal, prolly
not normal to have one lying about when a bolt strikes and noticing it light
up though ;)

Hi Andrew,
I tend to agree that what you said was needed. I am new to the list and
don't know anyone here but i can tell that this list is a *small* group of
people conversing about a passionate topic. Seeing somosne post a letter
saying 'goodbye' means something/someone went too far. Being on lists
previously, this type of bickering/arguing/discussion/whatever is the type
of thing that can destroy the entire forum and i doubt this list has enough
new subscribers to keep it going if this were to happen.
Soloution: stop all this bullshit - the more everyone comments the more
chance of someone saying something to offend another person and hence
alienate them. All involved - kiss and make up.
All the best and looking forward to getting to know everyone.
Lyle

HI All,
In regards to that storm we hit in Singleton yesterday, it seems that this
cell has caused a bit of damage to a town just north of singleton.
Reports are through that up to 20 sheds and farm houses have been damaged
from the microburst winds out of that new cell we encountered there. From
whgat we saw and drove through It does not surprise me at all. The RFB of
this cell was amazing, so dark and ready to dump its load any second, and
when it did (right on top of us ) the wind was amazing, and we also did see
branches lying on the New england Hwy just to back it up. A very nice storm
!!
But the amazing feature was the raised dust being sucked up into the
updraught of this new cell. Absoloutly amazing sight !!!

Fair enough, im not going to comment on this Halden issue, there are good

These comments are totally uncalled for. No one on this list gets "laughed

Everyone is free to post there thoughts/ideas/experiences, and they do!
Totally uncalled for, get over it.

Yeah sure, that is true, no doubt about it, but what if you come from
Victoria and rarely get good storms, you have to chase the thousands of
km's! (sorry Vics couldnt help myself there hehehe )also, if you want
more storms, more chance of seeing severe weather, and to see alot more of
the country than the Sydney basin, you chase. I loved every minute of the
850km off chase we did yesterday, our target area was SPOT on where the
action was, and its the 1st time id ever seen hail falling in 41+ temps !
Amazing stuff.
hmm i think we are all starting to sound like a bunch of winging yanks/poms
;) ( no offence les's hehehe)... lets stop all the fighting and move on.
This is EXACTLY how other lists die. We have done well to avoid it for over
a year now, and lets not let this ruin aus-wx.

No need to apologize. But I do very much appreciate this message.
Sometimes I am afraid I get very close to fulfilling the reputation of the
'Yank'. That is not what I want to do nor do I wish to detract from the
focus of the group. It is your list and I am the interloper.
But again, thank you very much for these words!

Come on Andrew and Halden, aren't you being a bit thin skinned!
I have seen nothing on this list to justify the petty profanities in
your emails, and whether you agree with the specifics of Blair's earlier
email
or not the basic message that "we should all be careful about making
statements
which might be construed as warnings" is absolutely justified. I'm no legal
expert
(do we have any lawyers present?), but there would seem potential litigation
consequence here if someone acts in good faith, only to experience a loss.
Personally, the more important issue is that as amateurs it is easy to call
every major weather event as false alarms have no consequence, and it is
easy to dismiss warning failures by "professionals" as incompetence or
similar. While the flooding in northern NSW looked a distinct possibility
(as forecasted by Halden - and obvious to anybody with access to the
precipitation progs which litter the net!), the fact that BOM warnings
occurred sometime later does not reflect anything other than a greater
aversion (and sensitivity) of the forecasters to false-alarms. Anyway, I
guess what I am saying is there is a danger of unfairly undermining
confidence in warning providers such as BOM, though the issuance of what
might appear as warning on this list.
As for "foreign" WX reports, I appreciate the one or two posts (often less)
we get a day, particularly as these usually clarify news items we see in our
mass media.
Of course, we don't want these ever to come dominant....
Anyway, on something meteorological - snow cashing. It is seem pretty likely
that the Tasmanian's on our list will get a chance for some snowball fights
on Sunday morning, if they can find a hill higher than 1000m. Victoria,
looks marginal, though the latest GASP and UK progs suggest Baw Baw (and
possibly Lake Mt), may get a dusting.
Just my two bobs worth..
David.

I guess I am guilty of bringing in far too much US weather. Yes,
you are
right, this is Aussie Wx and not others weather.
Well, if I've brought in too much Northern European weather then I'm sorry
but I generally reply to queries made by Australians about severe European
weather, nothing wrong with that surely????
Funny that there wasn't a problem with European members joining MSC
/ ASWA when I asked about 9 months back....
However I'll not say anything in future...

Reply-To: aussie-weather at world.std.com
I think this issue is getting out of hand. My initial
response was not to add further to this
debate however I strongly feel the need
to say the following:
Firstly, I agree completely with Jane - this list is
VERY positive, I have learned a lot and met some great
people who share a common interest - I really want that
to continue..
Secondly the list is open to all who have an interest
in Australian weather and people should be and are
free to say whatever they like.
Having said that there are some constraining factors which
apply whether we like them or not (even though I know
some people think it is bullshit).
1) The law of defamation.
If you post something defamatory to this or any other
list and you risk being sued as an individual; you
may also result in the listowner(s) and various ISP's
being sued. As a free list, if individuals wish to
risk being sued that is their business. I am however
concerned if other people are inadvertently put at
risk of being dragged into such proceedings by virtue
of doing the great public service of getting this list
going in the first place. I think everyone knows this
which is why it has not arisen as an issue. Because it
hasn't arisen as an issue doesn't mean it is not there;
its like gravity we don't argue with it, we just work
within the framework.
2) Liability for advice
In this increasingly litigious age, the provision of
advice (especially if given on behalf of, or purportedly
on behalf of organisations which may be seen as having
particular expertise) on which people may rely could
again result in a legal claim if loss or damage occurs
as a result.
The threat of legal action may sound far fetched but
there are a number of legal firms making a good living
out of running class actions against organisations
that offer or purport to offer professional advice.
They are aggressively pushing the boundaries of personal
injuries and economic loss cases and have had considerable
success in extending the application of the law into
areas previously free of litigation. (I could go on
here but won't at this stage.)
I am sure the BOM is somewhere in their sights as a
potential target for litigation given the right
circumstances and client.
Personally, I think it prudent to leave the risks associated
with the issue (or non-issue) of warnings to the BOM.
Obvious personal opinions purporting to represent
no-one but ourselves as individuals should keep us well
away from the legal pirhannas.
If ASWA or any other organisation want to get involved
in offering professional advice (including warnings)
then we should get the appropriate insurance (and the
premiums would probably mean that membership fees would
go through the roof and lead to the end of ASWA). At
the very least an appropriate, prominent disclaimer
should be displayed - as quite a number of auswx members
with their own wx web sites which could be even remotely
construed as offering professional advice - currently do.
Halden's post did have IMO have a feel and similarity
of style of an "official" warning - it certainly could
be perceived that way by someone not overly familiar
with BOM products (and a court may find that to be the case).
I don't think that Halden's post did any harm in itself
but raised some issues which I think were quite legitimate
to be raised about future posts in that sort of style.
Whilst it was clear to me that the post was not an official
BOM warning, it was not clear to what extent there may have
been official ASWA sanctioning (ASWA was in the header).
Also the post did say that the BOM would issue a warning
in the next 24 hours (which did happen) - it was not
clear whether this was a personal opinion of what would
happen or based on a discussion with a staff member.
I would have liked to have known which was the case.
The issues having been raised in the post are, I think
legitimate for discussion on the list - I don't think
Halden or anyone else should be upset by that. I have
enjoyed Halden's posts and am saddened that he feels the
need to leave - but that is his choice.
3) Lets be sensitive to the needs of people on the list
(ie BOM employees who are in a special situation given the
subject matter of the list)
We have on the list a number of people who are employees
(or otherwise associated) with the BOM. Again I think they
make a great contribution and would be a great loss if they
felt uncomfortable being part of the list. I think we need
to be sensitive to some of their issues of concern. For
whatever reason competition from other organisations for
various BOM services is obviously an issue of some sensitivity
for BOM employees; as is responsibility for public safety and
issuing of warnings. Note I am not advocating censorship of
postings but sensitivity to issues of concern to members of
the list and THINKING about possible implications for others
BEFORE posting.
4) Freedom to criticise other posts
As a free list, once you post, your post is in the public
domain and is open to comment by others with differing views.
Such criticism is healthy and should not be discouraged
- provided again it is done with senisitivity. I fully
expect this post to attract its share of criticism or
disagreement - if I am not prepared for that, I shouldn't post.
Where you do disagree with a previous post, I think it helps
everyone if the reasons for your disagreement are set out.
Personally, I find terms like bullshit and persecution don't
add much value by themselves. If you think something is
bullshit, by all means say so - but you should also say why.
You may think it is self-evident but others may not be so
clear (including the person who originally sent the post that
you disagree with).
I think the rule is focus on the post and not the person.
5) Geographic scope of aussie-wx?
Weather does not know national boundaries. I enjoy hearing
occasional stories about interesting weather overseas
- I haven't got the time to subscribe to ten or more other
wx groups in order to do this.
Such posts should be to the point and clearly titled so
others without that interest can use their delete buttons.
I actually think the current level of discussion of o/s
weather is about right and would hate to think that some of
our current contributors felt disinclined to continue their
contributions at the current level(ie Les UK & US).
Indeed some discussion of o/s weather can improve our
understanding of Australian weather ie knowledge of
the processes involved in great plains supercells may
help us understand some of what might be going on in
our own inland storms that our low population makes it
hard for us to find out about. Similarly, UK tornadoes
probably have a lot in common with cold season tornadoes
in WA and SA.
I personally think that NZ should be a legitimate part
of the subject matter of this list. It is close and
has some quite different and interesting wx patterns.
They also have a more privatised wx service and fee
for service regime - the impact of which should be given
more attention on this list. Given the NZ population base,
it is unlikely that we would end up being swamped by
our Kiwi friends. (Comments on this please...)
I think this list from time to time gets quite a few off
topic posts that are of a lot less interest to me and
many others than the relatively few posts about o/s weather.
Finally, in relation to aussie-wx, while it is great
that the list is growing as well as it is, it should
currently be probably better called "aussie-coastal-wx".
With the exception of Wychieproof (spelling?) and I think
someone in NE Vic, all other contributions are from people
within 200km of the coast.
We really need some people on the list from the interior
of our vast continent - Alice Springs or some of the other
inland towns would be great. (The tableland dwellers of
NSW and ACT do not have coastal climates but they are
also not really inland climates either.) Thanks to the
chasers and their reports, at least we have an occasional
indication of some of the goings on in the interior.
Sorry for the essay - but I do feel quite strongly about
some of the above.
Patrick

Sydney,
Its great to be back again! Its even better when the tempereature is
above 23 degrees as well. Very rough flight yesterday afternoon, observed
some excellent cells to the north of sydney, quite annoyed too! Couldn't get
the camera out of the bag because the seat belt sign was on. On arrival
(5.30pm) the current temp at Mascot was 31 degrees with a light easterly, no
more than 5 minutes later it was 21 with a southerly gusting a good 35
knots.
It is these sought of days that have been missing in recent years,
statistics show that a southerly buster in sydney should be experienced at
least three or four times within a summer period, particularly in summers
early stages. It is often assosiated with a spectacular roll cloud, although
not always, and replaces very warm north-westerley air. The problem is, i
gather is that regular north westerlies have been largely absent for a
couple of years. (97-98 a good year).
The buster itself, as you south coast people would know arrives
with great unexpectant force and i must say if seen approaching looks very
threatning, particularly with storm activity in the area. The speed at which
the front moves depends on the temperature difference beetween the air
behind and and ahead of it. As a general rule the faster the front moves the
greater the temp difference. As seen yesterday for instance, with a sharp
drop of at lest 10 degrees. What i really like about these changes is how
shallow they are, affecting areas only east of the mountains, particularly
on the coast, and only short lived.
After a night of strong southerlies here in sydneys east, this
morning was warm and scud free with light westerlies again. Amazing stuff
aeh. A complete turn around in lets say 2 hours.(MELBOURNE WEATHER!)
Anyway folks, once again its great to be back and Jimmy, see you
soon! Regards JAMES.

Try Hobart... Hardly ever see thunderstorms in Tassie at all... In fact I
saw more lightning and heard more thunder in one single thunderstorm last
summer (we had 5) than in the previous six years all together! (Shows you
what an unusual summer we had in 98/99)
However, I do recall hearing a weak tornado happened somewhere in the
Midlands in 1979... Anyone has any data on that? :)

I can't speak for everyone - but i have never heard anyone complain
about people from overseas sending emails about their weather.. please
don't take one persons comment as everyones view - if Andrew Puddifer
doesn't like this list, then no-one is stopping him from leaving..

Can anyone confirm media reports this morning of damage
caused by wind in yesterday's storm that struck Sydney's
southern suburbs? I've heard tales of a microburst nature
which is really interesting. Why? The narrow-scale radar
image was most unusual from one image to the next,
precipitation rose from nothing to +100mm/hr in one
particular area. I wonder whether this sort of thing, the
rapid onset of precitation) represents a radar-signature
of a microburst...

I dont want to stiffle any debate , viewpoint etc, BUT maybe now this is all
out in the clear, people are aware of how other people feel about certain
things - we can put this behind us, let bygones be that and start afresh from
here on in. Remember that conflict can be also a positive thing - ways that
enhance the list and give it new direction.
:)
Anyone disagree?

Seeing as we're all into expressing individual opinions, I
think you'll agree, but no one is prepared to point the bone,
so to speak, that I am one of the sources of "Bovine Excreta"
spoken about on the list...I take no offence whatsoever, nor
would I be offended and leave the list or resign from ASWA
if someone told me off. That's life! Facing up to every issue
and dealing with it is what makes life interesting and we
humans very adaptable. Let's hope we can apply this to the
big picture items like "Global Warming" etc. In this Bovine
Excreta, I'll cover;
1) On Issueing Warnings
2) On the scope of Aussie Weather
3) On "Pulling out of ASWX"
Please digest:-)
---
Issue 01 - Bovine Excreta News
==============================
1) On Issueing Warnings:
Not a problem. Using the list, just point out the obs and
tell the BoM to go check it out . Many BoM people are
subscribers to "Aussie Weather" and some are also ASWA
members. If you are a registered BoM Storm Spotter, there
are formal channels and procedures to follow for getting
storm warning info into the BoM. These could do with some
fine-tuning as MichaelT can testify:-) The only issue left
undone is how warning info on this list can get into the
BoM "formally" so that we all know that the matter is being
dealt with by the proper BoM people in a timely fashion. I
have a vested interest in this due to a background task of
automatically analysing BoM radar gifs to track storms...
and perhaps issue storm tracking info automatically to a
known E-mail destination...
Unfortunately, ASWA is not a registered emergency services
organisation able to issue formal warnings so ASWA members
need to use the BoM, State Emergency Services, Police or
Fire Brigade in their area to get a proper warning out.
Only after this is done should anyone speak to the media.
If you think ASWA should become a registered emergency
services organisation, please feel free to suggest it to
the ASWA Committee (see http://www.severeweather.asn.au ).
Having investigated this option in my capacity as ASWA
Treasurer to address the GST Issue, this is a major change
in the scope and rules covering ASWA with no guarantee that
an application will be successful.
2) On the scope of Aussie Weather:
Aussie Weather (aus-wx) is not ASWA or vice-versa. Please
don't confuse the two though it would be confusing to
have a list for ASWA with another for Aussie Weather. Nor
do I believe that aus-wx scope ceases on Australia's
geographic borders. Discussion in the list should focus on
Australian weather for sure, but that, as you know, is
caused by events that are essentially of a world-wide
nature. It's also interesting and very benefitial from
the educational perspective to look at the activities
of other people in different countries with a similar
interest. They might also have a more innovative approach
which we can learn from.
3) On "Pulling out of ASWX":
People who have been the victim of a media feeding frenzy
and/or resulting litigation would relate to this - A very
dear relative of mine said some things in a "open" forum
back in 1986 that were written down, taken out of context
and then published in a double page spread starting page 4
in the Sunday Telegraph. The retraction was 3 lines on page
57 some weeks later. The main issue in question was finally
"settled" late last year. Yes, that's 13 years later! Not
one apology was issued e.g. "We're very sorry to have
f*****-*p your life..." and any compensation matters were
settled at forced retirement back in late 1990. The damage
had been done years before and it began the finish of this
relative's career. It also led to many extremely bitter
memories. It could lead to the break-up of a 40-year plus
marriage due to excessive drinking and sometimes violent
behaviour. This is the price of bitter memories. I don't
want this to happen to anybody. No person deserves that
kind of unfair, costly, inconsiderate and cruel treatment.
I may be quilty of an over-reaction, if anything. But
those who read my words about what Halden had written
would have understood one thing very clearly. I wanted
to protect Halden and ASWA Inc. Nothing more, nothing
less. Far from getting a "raw-deal", there's a subtle
lesson-of-life herein for everybody. That is..."No open
forum will ever protect you, only you can ensure that..."
I also refuse to subscribe to debates about what Halden
wrote. If you have a UNIX box, just save the original
E-Mail as a and run...

I was just reading an excerpt from the BoMs website and came across this:
"22 November 1992
During the early hours of the morning, a tornado severely damages over a
dozen houses, destroying several in the north west Tasmanian town of
Smithton. It is the State's most intense tornado, with estimated winds of
280 km/h which also flatten hundreds of large trees along a 15 km path."

Hi John and all,
Currently my backyard shade temperature is 44.7C - Brisbane AP at 1pm
was 38C, the Jan record is 38.3C - we'll probably break this, with the
highest record at the AP being 39.6C - another possible contender to
break the record...the only thing that can ruin the record is the
seabreeze...now you watch the seabreeze come in at 39.5C...

Hi all.
In media today - that storm I mentioned to you all esp: re lightning - we have
had some figures released today from the BOM's Lightning meter at the Airport -
an amazing 1438 bolts were received during that storm. Not bad hey - from 1
storm only.

Rapid decent of a high reflectivity core from aloft can signal the immanent
danger of a microburst. Moreover, when surface temperatures are so hot,
even with relatively high dewpoints, the temp - dewpoint spread can be
large (up to 40 to 50 degrees F) and the low-level lapse rate may be dry
adiabatic. Conditions such as this are prime for microbursts. In the US,
several years ago, a major airline crash occurred at the Dallas-Ft Worth
airport in exactly these conditions. The surface temp was ~ 102 degrees F
and the dewpoint was ~ 60. Precip opened up over the glide slope and
runway just as the aircraft was making its approach and they encountered a
rain-filled (wet) microburst, underwent a stall from which the pilot could
not recover, and nosed in to the runway.

Hi Anthony.
Unfortunately I am now at work, not home (actually fortunately because it is
A/C!!!). Last temp at home was 35C at 11:30am. The NW'ter still has quite
a bit of steam in it here at Sumner (ha ha), so no seabreeze just yet. But
ho!! Is that Cu I now see popping up down South?? Don't have an accurate
thermo here, but according to the dodgy decorative device it is 39C on the
balcony with 40% RH at 3:00pm.
I know these sort of temps are not remarkable for places like Adelaide or
Perth, or even western suburbs of Sydney. But for Brisbane they are a real
rarity due to our normally high RH's. Record High's will be all the more
amazing after the recent run of record low avgs.
Not sure what the record is for Ipswich, I recall a 43C+ out there a few
years back, but I don't think we'll break that today.

I'm sure most people on the list dont have a problem with overseas posts
about their weather every now and then, it doesnt happen often, and most of
us find it interesting anyway, as it its about the weather, and thats the
subject we like to hear about.
About the ASWA and the list, they are both seperate like most of the others
have said, and anything that is said on here doesnt imply thats its to do
with the ASWA, but if someone uses ASWA in the subject header, then it
would most likely imply that email is connected with it and some people
reading it might consider that it comes from the ASWA and thats what we
have to be carefull about.
For anyone that hasnt done so yet, please read the Aussie-weather list
guidelines at:
http://www.iinet.net.au/~jacob/auswx.html
Also, for many of the newer people to the list and older ones that havent
tried it yet, a lot of us chat live on IRC, on the austnet network on
channel #weather
We generally dont have the weekly meetings on IRC anymore because each day
and evening there is usually enough people on to talk too, so its almost
like the old weekly meetings each day. If you havent used IRC before and
dont know how to get on, go to the guidelines page above and at the bottom
of that page there is info on how to come on the channel.
Thanks.

I don't have any data on the tornado that occurred in

Hi Anthony,
I've been following this with interest in the Brisbane RFC today -
Brisbane airport number 1 reached 38.4C *just* before the seabreeze kicked
in and knocked it down. At the time of this maximum, the DP was sitting at
23.1C. It was interesting that the eastern part of the airport received
the seabreeze quite a while before the western part. At the present time
(4.00 pm EST), Amberley is sitting at 39.4C and DP 17.9C.
We've just had Channel 10 up here interviewing the SPOC, so that should
appear on the news tonight. The other stations have called, but I don't
think there have been any other interviews.
Cheers,
Jonty.

Well it's hotter than was expected in sydney today.
The forecast for the city was 29, it's currently about 26
The forecast for the west was 36, but temperatures in the west are between
37 and 39
At my house in Ashfield, it's currently 39, which is the highest so far today.
I'm less than 10km west of the city, and there's a temparature difference
of about 12 degrees over that distance.
The maximum here yesterday was 37.8, which is lower than the 40+ that was
experienced further west because of the increasing cloud in the afternoon,
and the change that came through earlier and sstronger than it did further
west.
Today the sky is cloud free and the temperature appears to be still
climbing so we could crack forty yet :)

Hi again.
Just a bit more about the weather today.
The dewpoints have been fairly high. At 3pm today Canterbury Racecourse
AWS, which is about 2km south of here, had a DP of 19 and a temperature of
33. The dewpoint may have gone down a bit since then though, there seems to
have been a movement of air from the north west, the temperature rose
fairly rapidly over about the last hour.
however yesterday, the 3pm dewpoint was 20, and the air temp was 37.

Hi Jonty, everyone..
Apparently we broke the record for the highest max in January today? The
max at the aiport was 39.1 - the previous highest being 38.1 in 1985.. i
got this information from someone at the BOM..
DP's were quite high in coastal parts today - Coolangatta had 32c and a
DP of 25c mid afternoon.. Brisbane airport also had a temp of 33c and a
DP of 24c around the same time (these are all weather underground
observations - they seem quite accurate)..
I also reached 38c in Redcliffe (official max) which is horribly hot for
me - normally i'm 2-3c under the Brisbane max temp, but NW or Westerly
winds stuck around for most of the day..

Sender: aussie-weather-approval at world.std.com
Reply-To: aussie-weather at world.std.com
Hi all,
A scorching 39.1C at the AP today...my thermo reached a shade
temperature of 45.5C! I have noticed that it tends to read higher than
it should on still days - and despite the warth, it was surprisingly
still for most of the day until the seabreeze came in dropping the
temperature to 33C in just over an hour.
At 2pm, the Brisbane Airport was 36C with a 24C, giving a sfc CAPE of a
nice 4916! Unfortunately, the cap was just far too strong.
Given todays efforts, I'm not holding my breath for storms tomorrow,
even in SE QLD although there is the risk of something on the ranges.
The cap will continue to dominate, even though CAPE will probably be
around 5000 again. I don't like those SW'ers so close to us either.
Saturday has slightly more potential, border range storms and isolated
storms around SE QLD will probably be the likely outcome IMO. The cap
will be weaker, and the trough will still be closer to us. But as for
Brisbane potential, again - I'm not holding my breath. The winds will
be more N'ly than NW'ly - and the winds behind this won't be quite so
SW'ly, so that's one (or two) positive notes.
Sunday looks like the best (and quite possibly the only!) day for storms
in Brisbane, and in SE QLD. With a geostrophic N to NE wind throughout
the day, with a SE change in the afternoon. This is a much better
situation, and I'll definately be making sure I keep my chase resources
for Sunday! The cap will be much weaker too, no more 25-27C at 850mb,
rather 18-20C at 850mb, a much more respectable figure.
Any other people's thoughts on the SE QLD potential over the next few
days? Now that I've said something, there'll be storms on every day but
Sunday :)

Hey everyone,
The late westerly winds that kicked thru in Sydney round about
5pm have caused the dropping temps to rise again.
Sydney City
1930 34.7
17
1900 31.9
25
1830 27.6
65
1800 27.8
62
Most other stations have leveled out and are quite warm
for 8pm. Also in many part of Sydney the air pressure is down below 1000,
which has also been rare recently.
In discussion on #ICQ, it was noted that most of the storm
activity this season has occured west and north of Sydney, with most of the
bigger cells forming in the Sydney Basin, not roaring up from the south as we
have been accustomed to other seasons. Indeed this season will be known as
the season of the westerly, in
Sydney.

I realise that this is not a AWSA list - hence why I have stayed out of the
debate as Vice President of AWSA, until now.
Please can we just wind the clock back a week and pretend nothing has
happened.
If people are offended by one person's remark, then realise that that is not
the general consensus of the group. Please just ignore the post.
Somebody pretty much wrapped it up in an earlier post in saying that the
longer these sort of debates go on the greater the chance of somebody
getting offended.

I'm not leaving the list at all - just going to lurk around a bit, after all
I'm a paid up member of MSC / ASWA and I ain't gonna miss these reports of
golfball sized hail, huge rainfall totals, supercells, tornadoes,
gust/dustnadoes or downbursts.... not to mention red on radar over Sydney /
Melbourne / Darwin or wherever....
Please don't let aus - wx go the same way as wx-chase!
Weather is an international thing, this list isn't exactly swamped with non -
Australians talking about non - Australian weather, i believe there's three in
all!
BTW Scots are not whinging poms I believe that expression is for English
British. (:

The internal weather stations at my work recorded just over 44C at Victoria
Park today (northern outskirts of the Brisbane CBD). This was a one minute
average from a properly calibrated instrument. Out of interest, work also
has weather instruments at Meeandah Substation. About 1 km away from the
BOM Brisbane Airport station. It registered 39.2C. Weather stations at
Southport and Mooloolaba both went over 40C (this disagrees with BOM data,
local geography is a factor here).
If you have ever wondered what the weather does to the price of electricity
have a look at the NEMMCO web pages at;
http://www.nemmco.com.au/nem_resources/market_data/graphs.htm
The Queensland spot price is current shown here;
http://www.nemmco.com.au/mms/GRAPHS/GRAPH_5QLD1.HTM
The "spot" is around $30-40 per M.Wh. Presently, it has spiked over $5,000
per M.Wh! Ouch. (PS. domestic consumers do not pay the spot price.)
Accurate prediction of temperature is very important to the power industry.
It takes 24 hours to "cold start" a coal fired generator. Reduce this to
about 8 hours for a "warm start". Gas turbines can start in about 60
seconds, but they guzzle fuel. It is a black science predicting power
consumption 24 hours in advance - factoring in official BOM forecasts and
the public's behavior. (I reckon the best one's ignore the computer
prediction and secretly consult tea leaves:).
Regards,
Anthony Spierings

I back the comments made by the fellow weather mates.
I have only been getting used to the comments made by
Les cause i have only been interested in the weather
since June last year and still learning the termonolgy
as new people go through when they have new interests.
So please Les stay with the list as i will miss some
of the comments made by you.

Nice variation on Sydney Harbour tonight. Wedding Cake Is had the
seabreeze up to 8 pm. Temps at 8 pm was 23.4 but by 9 pm reached 33.9 -
a 10.5 degee C jump AFTER sunset - pretty unusual but on Christmas Day
1957, the temp jumped by 75F at 6 pm to 101F just before 8 pm -
remarkable effect of blowing out a sea breeze.
