Criss and others,

I am going to answer this question quickly. They covert it to sea level ("QNH"
comes in somewhere here??) by using the altitude of the measuring station.
Someone else may have a more precise answer on how they actually do it as I
have forgotten.

By the way I went on a 2 day chase last Thursday and Friday. 850 km and 5
storms later I feel satisfied again. No hail but heavy rain (not much all up
though). Good gusts out the front of the storms (about 80km/h on some looking
at the damage with many trees loosing big branches). water over roads in some
places and some good lightning (though I missed most of it on film).

All in all an enjoyable time but a really uncomfortable sleep in the middle. I
think I might take a pillow and mattress next time.

Morning all. I hope our wealth of information friend Blair is on today as I
would be interested to see Kempseys rain data for yesterday. Not only did
they get that severe storm BUT then last night a stiff SE developed and in
rolled either a cb or a massive congestus and dumped more rain in that
area. Looked quite impressive for some hours. Port Macquarie received a
decent fall (this would have to be confirmed by Blair) but I suspect the
hills behind Kempsey / Port area would have very decent falls last night
(possibly over 100mm).

Hi all,

Just some additional information, I was informed that the township of
Casino was blacked out last night.  This could have quite possibly been
the very structually strong looking t'storm to the S of us that we
couldn't really get to, and when we got up close, looked weak.  But it's
anvil was very thick, defined and crisp, it backsheared nicely and had
some very strong updrafts.

Also...when I got home last night, my mum informed me (her exact words)
"Stanthorpe received something severe from a t'storm today" but I
haven't heard anything further on it.

Border range t'storms often have me curious, as quite often they look
strong and sometimes severe from a distance, unfortunately we weren't
able to observe any 'internal features' from them, but that was because
we left too late (although we couldn't have left any earlier)
unfortunately, as they move off the ranges, they tend to collapse very
quickly unless there's sufficient heat and/or instability to keep them
going.

Anthony from Brisbane

enough proof for me.)

Hi Paul,

I have checked the rainfall registrations from the Bureaus Daily Rain
Bulletin and found the following

Kempsey 38mm
Port Macquarie AWS 37mm
Smoky Cape 26mm
Mt Seaview 13mm

The highest rainfall I could find in the state was at a place called
Mallanganee in the Northern Tablelands which had 63mm.

Highest daily reporting stations in this region were Kempsey 38 and
Port Macquarie 37. There might well have been other stations that got
more but don't report until the end of the month.

On the Northern Tablelands Mallanganee got 63 and Drake 39. I must
confess to not having a clue where either of these places actually 
are :-(

Daily rain bulletins for each state, and the 0900 and 1500 weather
bulletins for each state, are freely available on the Bureau web
page (www.bom.gov.au) - look under 'Observations'. Generally the 0900
and 1500 bulletins appear about 1 hour after the observation time,
and the daily rainfall bulletin sometime between 1000-1100 local time
(remember to adjust for time differences). With a couple of exceptions,
if a station reports daily, it will appear on one of these bulletins.
(The main exception I can think of is Wittenoom - the state government
is trying to close the town down, because of the asbestos, and doesn't
want other government bodies to acknowledge its existence - but the 
observer is one of the few remaining residents refusing to leave, and
because it's a Reference Climate Station the station will stay open
as long as the observer stays, so it still reports but isn't included
on public bulletins).

As Michael Fewings has pointed out, the readings are 'adjusted' to
mean sea level.

The process for doing this is complicated - mainly because the 
pressure change with height in the free atmosphere is dependent on
the temperature of the air as well as the altitude. As we obviously
can't measure the temperature of a column of air between a high-
elevation station and sea level, various fudges have to be employed to
estimate the nominal temperature that such a column of air would 
have. There's no internationally agreed way of doing this, which means
that sea-level pressure becomes an increasingly problematical 
measurement above 500 metres or so.

The adjustment method used in Australia is based on the altitude of
the site, the mean monthly temperature and the temperature at time of
observation.

Hi Blair and Others,

The towns of Mallanganee and Drake are to the west of Casino on the Bruxner
Highway. Mallanganee is closer to Casino than Drake which is up near
Tenterfield.

Decent rain is falling along the Coast as we speak. Taree (as far as Im
informed) is on the receiving end of some of it. Those with access can they
pull up Taree's AWS and see what the last 24hrs was? Thanx.

Hi Paul,

The Taree AP AWS 24hr total was 8mm. The other Taree reading available was
5mm.

No a dumb question at all, Chris. What the correction of barometers
each day before reading is assumed that a real site at sea-level 
nearby is experiencing the same atmospheric pressure as if the 
elevated site is reduced to sea level as well. This, of course 
assumes that the MSLP weather is also very similar between nearby 
points at different altitudes.

The BOM produces for aviation needs and observation posts the mean
sea level pressure at that site at particular times of the day. 
The observer or aviator can then correct their barometer or 
altimeter accordingly. In the case of the altimeter, the altitude
can then be derived. Otherwise, if you're in an aircraft on the
ground at a known altitude or you have a barometer with an adjustment
for this purpose, you adjust your altimeter to that known altitude. 
This will also give the reading assumed at sea level for that point
on Earth. It is from the latter that MSLP charts are produced.

It gets a lot more complicated when mid-level pressure systems are
involved and different since way up, you'll experience quite a 
different regime to what is happening at sea-level. For most
elevations where people live, this is not an issue. Perhaps the
BoM can comment further.

Hi All,

Congratulations to the NSW people for having some storms to chase as well
as the WA people for having plenty of tornadoes and storms too.

Victorian forecast for the next few days looks pretty good.

Thursday will be generally cloudy with isolated showers and thunderstorms,
mainly in the west and north, as a low pressure trough extends over
Victoria.
There will still be a few early fogs in the south and the day will be mild
to
warm with chiefly light wind and afternoon coastal seabreezes.

Showers and thunderstorms are possible in most districts on Friday and
Saturday,
as the low pressure trough remains slow moving over Victoria. After morning
fog
patches, mainly in Gippsland, the days will be mild to warm with a light to
moderate northeast to southeast wind and afternoon coastal seabreezes.

Courtesy of the BOM.

And Sunday is supposed to be about 32C with thunderstorms as well so
melbourne may fire (once again).


Some people may find this interesting.  I found this on the Texas
Tailchasers Stormpage which is created by US chaser Steve Miller.  These
are his definitions (i guess you could call them) of storms:

Marginally Severe - Storms with very minimum severe criteria with 60mph
wind gusts and/or dime size hail. Yawn. 

Severe - Storms with at least minimum severe criteria. Wind gusts to 75mph
and/or hail up to golfball size. Usually a slight risk of a tornado. Just
enough for me to keep an eye on the radar and NWR turned on. 

Very Severe - Storms that scare old people, small children, and small, cute
furry animals (small dogs should take cover). Wind gusts up to 90 mph
and/or hail up to baseball size. Usually a slight to moderate risk of a
tornado. I seriously consider (and often do) call in sick or change my
social plans. 

Extremely Severe - Storms that create chaser nirvana, ecstacy, stormgasm,
and the forbidden sacred dance of chaser merriment. Normal, sane and
rational members of the community are terrified and seek shelter
immediately. Wind gusts exceeding 80mph and/or hail up to the size of small
watermelons. A moderate to strong risk of tornadoes with significant
tornadoes expected. Unless I am in an Intensive Care Unit with a ventilator
crammed down my throat, IV tubes everywhere, and a mean 300 pound nurse
between me and the exit...I will be out there for sure. :-) 

So there you go......

End of my weekly speil (until things start to happen around here tomorrow
or friday).

Andrew McDonald.

The AVN LFTX forecast is looking alright at the moment for Friday for

afternoon. There is an area of -8 at 27S and 147E at 03Z and that area 
grows at 6Z. There is also plenty of -4 or lower on Friday through these 
areas. Hopefully the forecast changes just enough to make it more within

Hi Matt,

It certainly was a shock here as well!!! Thought the building was starting 
to collapse at first !!! I have just heard on the radio that it was a 4.5 
quake centred on a town called Appin.

Just heard on the news about the earthquake and I thought what bloody
earthquake!!!. Didnt feel a damn thing here. Not even the slightest hint.
Ive heard that some homes have lost power in Appin near where the epicentre
was located. Apparently it occured about 12km or so beneath the surface.

Earth tremmor of mag 4.5 5km south of Appen.

It was felt from wollongong up to Newcastle, and caused a blackout
in Appen but no other reported damage.

Lucky you!!!!

Im located at the top of MIller St, North Sydney in a 13 storey building. 
Maybe being high up in a building is why I felt it?

Some other figures from last night that may be of interest.
Telegraph Point 27 mm
Euroka and Millbank both 52 mm. These are upstream from Kempsey I
gather, in the Macleay Valley. Millbank reported 33 mm in the hour from
7.40 pm. 
West Kempsey AWS had 56 mm.
Bowraville had 31 mm and another 24, while Talors Arm had 25 mm
overnight and 29 mm between 11 am and 2 pm this afternoon (Wednesday

Everyone I have great news.

Dept fair Trading lost our appln for incorporation BUT I talked to there
head honcho guy in Sydney and we dont have to incorporate because we are a
volutray assoc. SO this saves us $110 (which I have to get back from them
yet) and means we can start things rolling with ASWA. So expect a
membership form tomorrow. Also it means interstaters can becaome members
without any worries. For bank accts etc all we will have to show is our
constitution showing that we are non-profit (that should shut the banks
up!!

It is different every day, I do not like the congestus to shoot up straight
and tall and form a storm too early. This is very much opposite to how I
thought a few years back. Nowdays I prefer to see congestus that gets
sheared early so the towers are 45' degrees, I also like to see the first
few congestus towers spread out into strato-cumulus, this means there is
capping ( slight inversion ), this acts as a dam, letting the bottom
atmosphere build up more and more energy. If the capping is not too strong
eventually after many failed towers one will explode through the cap and
grow into a supercell. Well that is the how iit supposed to work, but
everyday is different.

My chase reports and photos for 12-13th March 1999 are up at -

http://thunder.simplenet.com/chase/chase12.htm

http://thunder.simplenet.com/chase/chase11.htm

Th report for March 13 has some very interesting storm formation, I am sure
it was not supercell, but rotation is indicated at least at low levels.
Anybody care to comment either yes or no.

March 12 is for diehard chase readers, it is fairly unexciting. Be warned.

Michael...
I got an unconfirmed report that 148 mm fell last night at Lake Conjola
- I think that's near Batemans Bay. This seems out of proportion but
there were a few brief very heavy showers in the Wollongong and
Ulladulla areas so its not totally impossible. The fall included 70 mm
in the hour to midnight.
Have you heard anything?

I agree with you most of the way Michael. Stratocumulus broken in the
morning is good although I don't really like the flattening out
startocumulus situation so much. I do however believe the best storm
activity occur when nothing seems to happen with collapsing or weak cumulus
or storm cells during the early afternoon and then the cap breaks and then
it is followed by supercell or major storm development. This has happened
only a few times that I recall but boy is it worth it. In most cases you
don't really suspect that it will happen.

Hi,

I think at this stage we will discuss at our meetings across Australia what
will take place in terms of forms and membership. No forms whether it be
online or printed will be issued until it is discussed with everyone. But I
am glad that we will SOOON be able to make that move. Our meeting is this
Saturday so we will begin discussions then and give feedback to everyone on
the list.

I think everyone is aware is of the importance of the format and content of
the form so if you wish to discuss it, I think it will be important and all
committees will take notes of what was said and discuss at the next meeting.

I know that the yanks prefer their supercells to be isolated storms, so as
the updraft is not competing for resources. Kind of reminds me of a pic on
your site of the that Central Coast supercell, the one that only fits on 2
frames. It was a singular unit.

No reports that I know of, we did get around 10mm at 11pm last night. There
were showers evident in Kiama this morning and cumulus had vertical growth.

Interesting side note is the COLA MRF model nailed the NSW coastal rainfall
perfectly with a small little patch in the Ulladulla area, and a larger area
north from Taree. But the model missed many of NW slopes storms.

Matt is right, Lake Conjola is just north of Milton, Milton used to feature
in many ' highest in last 24 hours ' reports, but in recent years has lost
some of former glory ( same with Robertson and Mt Keira ). The ranges come
close to the sea in that area, but nothing like the Illawarra escarpment.

Regards
Michael

It was a singular unit but in one of the photographs you will see a second
storm to the north of it which I would say would be a supercell.
Incidently, that is one storm that also had weak storms around earlier but
that storm exploded later. That was Boxing Day 1993 and dumped 0.5 metre of
hail in Wyong

Another day is the day you had your funnel cloud.

One of my favourites was a day which was hot I recall about 36C. It was a
nothign day with cumulus developing but not doing anything. Then I recall
"tall" cumulus towers leaning somewhat at a slight angle. These were the
start of storms. Within an hour, St Marys was under seige of a developing
cloud base which approached and gave very heavy rain and hail up to 2cm. It
moved on within the next half hour and I recall observing the rear which
had a nice tail to it. It moved east and later in the evening back shearing
from the storm system produced intermittent hail showers. This was January
1986 if I recall correctly. I miss the mid 80's. Michael Bath can tell you
how many times I mentioned that phrase on the chases we have had.

It seems that the style of thunderstorms changes over the years and I
believe that we are re-entering a phase of tornadic activity. Will Sydney
begin to see this activity???

One question: what do you think of this storm...?

This is what we watched for about one hour before it dissipated when we
decided to move. Perhaps if we had stayed the storm would have remained
intact???
