Hi All Perth is have a small (minor) Heat wave this following week, the
exspected top is about 37 C till at least Thursday. With the west coast
trough not moving any were for the next 5 - 7 Days. We just might have
our hottest Christmas day in 20 Years, Yes 20 Years..lol. The record for
christmas day is 42 C , cant recall the actuall year this ourred, it was
in the 60's i think ( any one care to comment )... only time will tell
if we make it or not.
And to all on the list Have a Merry Christmas and a Happy New Year.

Hi Everyone,
I have put up my account of the 1989 SE QLD Christmas eve Tornadic
Thunderstorm on BSCH in the recent events section:
http://www.bsch.simplenet.com/products/recentevents.htm
This storm caused a huge amount of damage in Redcliffe City, with 500
houses unroofed, 1000 damaged and 17 or so declared structurally
unsafe.. 2 people were also killed, and several more badly injured..
The storm also produced multiple tornadoes during it's lifetime (which
could possibly have been up to 6 hours).. this is also the storm which
reached 23.1 km's in height (!!!!!!!!!)
There is even a picture of the gust front in the report!

Jimmy and all:
Storms producing all that severe and damaging weather are almost certainly
supercells. As I said, hail of that size can not be produced without a
mesocyclone. In my experience, hail greater than about 5 cm can only be
produced by supercells. The enhanced vertical accelerations created by the
turning of the flow aloft appears to be necessary to create the broad and
sustained updrafts that are needed for hail growth to those sizes..

This was a very good discussion. Good reasoning. Updrafts are very
definitely the location for large amounts of supercooled water. In fact,
it is these drops of supercooled water that become the source of most of
the mass of hailstones. They grow very rapidly in the updraft and in the
presence of this liquid water which freezes rapidly on contact with the
stones. However, the water does not freeze immediately due to the heat
exchange and heat budget of the stones. The largest stones often have a
10% to 15% liquid water mass that both coat the stone and that forms
trapped liquid within. Sometimes these stones reach the surface rather
"mushy" and can break up on impact with the surface.
It has been found that by the time the updraft temperatures reach -40 all
the supercooled liquid has frozen. Even here there is hail growth but it
takes place in a dry fashion (vapor to solid) and much more slowly. It is
in the wet growth that the lion's share of mass is accumulated. By the
time most of the updrafts reach the trop, the EL for most thunderstorms,
the updraft is much colder than this. So, at the tropopause and above, the
updraft finds itself colder, the higher it rises the colder, much colder,
it is than the environment. Note that on the IR satellite photos the
storms show up as being very cold......-70 to -100 or even colder. (It is
for this reason that the IR temperatures can not be used to estimate cloud
top heights. Thus, the glaciation (cloud water turning to ice) usually
occurs well below the overshooting dome level. However, during the phase
transition from liquid to ice lower down in the updraft, there are very
large quantities of latent heat released sustaining and augmenting the
updraft. BTW, most hailstones have as their cores, what is called graupel
(hope the spelling is correct but probably not [S]) or what can be called
pellet snow. However, sometimes you can even find insects that were lofted
by the updraft and become the condensation nuclei for hail growth.
Remember the discussions of CAPE? Also remember that CAPE is largely due
to the addition of latent heat. So, it is the initial conversion of gas to
liquid where some latent heat is released and then the additional heat
release when the phase changes once again from liquid to ice, that so much
of the potential energy of CAPE .....the P stands for "potential", is
released. That explains why so much of the CAPE is wrapped up in the water
vapor....humidity of the air.
Environmental shear and the fact that storms move more slowly than the wind
creates storm-relative, sr, flow. It is this sr flow as well as the storm
summit divergence that helps remove mass from the upper reaches of the
updraft and helps maintain the updraft.

Hi Blair and others,
Sadly, having worked in the newspaper industry (not in Sydney) I know
how much crap editors and subbies CAN (to be balanced, they also produce
good work) come up with. As a junior back in those days it was awful
just walking the streets after certain silly articles.
Its probably been discussed but has anyone thought of approaching the
papers about the said articles etc? Again, because its a "Weather"
article, somehow papers seem to get away with it, ie: few seem to think
its important, compared to other "Important" stories.

Perth's hottest Xmas Day was 42.0 in 1968 just behind Adelaide's 42.1
way back in 1888 as the hottest for any Aussie Capital
Let's hope we all "weather"the New Year in peace and contentment.

This reminds me of several aircraft accidents in Western Australia involving
the MU2 (This is a high speed twin turboprop that uses spoilers instead of
ailerons for roll control).
Both of these aircraft where believed to be flying through what a friend
described to me as super saturated air originating from decayed cyclones.
The aircraft skin is very cold, as it flys in cold air, it hits a area of
super saturated air with unstable super cooled water droplets that instantly
turn to ice on impact. Ice has several effects it adds weight and changes
airflow both have a negative effect on the aircraft's performance. Ice in
large quantities can also jam flight controls.
Both aircraft had autopilot on and accrued ice so fast that control was lost
and basically fell like a stone (large block of ice). At the accident site
there was no evidence of why these aircraft fell out of the sky because ice
melts.
Christmas morning is going to plan, the food colouring and chocolate has
kicked in, the dog has run for cover and you know who likes you by the noise
coming out of toys they gave.

I am finding this discussion interesting Leslie. And your comments lead to
two two discussions the first still on this storm event
http://www.australiansevereweather.simplenet.com/photography/photos/1997/121
9jd20.jpg
First, just to clarify, the hailstones of 5cm were reported from the
northern part of the so called squall line structure. The photos of the
base is given as the following sets of photos and all are related to the
same storm but intensifying somewhat as it approached the coast from about
50-60km west in the first photos. The storm is situated to our west and
then gradually to our northwest and north later in these images
http://www.australiansevereweather.simplenet.com/photography/photos/1997/121
9jd06.jpg
http://www.australiansevereweather.simplenet.com/photography/photos/1997/121
9jd08.jpg
http://www.australiansevereweather.simplenet.com/photography/photos/1997/121
9jd09.jpg
http://www.australiansevereweather.simplenet.com/photography/photos/1997/121
9jd10.jpg
http://www.australiansevereweather.simplenet.com/photography/photos/1997/121
9jd12.jpg photos 12 to 17
This is the storm that gets the mention in the database of 5cm hail and
damaging wind report mentioned in the previous e-mail. Again, we have no
clarification of what type of storm it was. I assumed that it was part of a
squall line system but you may be right - perhaps this particular storm was
a mesocyclone (supercell). From the studies, it is well known that a
supercell can develop ahead of the squall line system and perhaps gradually
become part of the system. You and others may like to shed light on that. I
only tread on areas which I am sure about - I don't like to say things I am
not sure about.
By the way, this is my account of the day
Mild. Humid. Early altocumulus and altocumulus castellanus with rain -
heavy rain and thunder. This moved to E.\\\ More cumulus congestus
developed with a thunderstorm around 11:30am to the S. The cumulus
congestus developed rain and thunder was heard around 1pm. At 1:30pm, I
headed for Oakhurst and waited for Michael taking 1 photo of a smaller
storm moving E. I then headed for Rooty Hill for more photographs. At
2:50pm, I went to get Michael from Mt Druitt Station and then headed back
to Rooty Hill. We took video and photographs of the storms moving E with a
light green tinge. Two roll clouds moved S and overhead as a result of
outflow from the storms. We then headed home. The back anvil gradually
cleared. A thunderstorm developed to the S during the evening. Hail damage,
strong winds, and locally heavy rain was reported in these storms.
Unfortunately, my description doesn't help as it is ambiguous to suggest
that the "storms" could have included or not included this particular major
cell. Oh well, I will try and ask the Bureau in Sydney and see if they take
an interest or not.
The second point I would like to raise is that you probably meant that
supercells are the most common cause of giant hail events ie hail larger
than 5cm. Please not that it is not so uncommon (no percentage or numbers
can be provided here) to have non supercell storms sending down giant
hailstones. A couple of recent good examples of pulse events were
The Dec 16, '98 storm was a pulse storm in Brisbane area - it gave 10cm
hail, two people reported it after measuring it with a ruler!
from Anthony Cornelius
And also a storm which Michael Bath and I have documented in the following
report
http://www.australiansevereweather.simplenet.com/storm_news/1996/docs/9602-0
1.htm please note there are also radar images of the storm (one of the
few times we could get hold of them)
For interests sake (when you get time) you may want to read the report on
the supercell on the same day

Hey All
Happy Christmas
Woke this morning to the banging blinds, the light ENE
of last night has now freshened considerably.
Took a look out the window and saw what every severe
weather watching hates "a full sky of cloud"
So after a few mutterings to myself I went back to
bed.
Got up at 9.30 and it was starting to look a lot more
promosing, the cloud had become scattered and some
sweet sun was breaking through.
And now at 10.50 good breaks of blue are evident, the
temp has risen to 25. There is a line of congestous to
the south and a nice looking Cb is to the NNW.
Atomosphere appears primed for storm development.
The fire weather briefing is a work of art, have a
read
"A high pressure system south of Tasmania will move to
the Tasman Sea on Boxing
day while a low pressure trough deepens over Western
Victoria. The trough will
then move gradually eastwards across the state on
Monday. The passage of cold
front across southern Victoria and Tasmania on Tuesday
will reinforce a cool
fresh southwest to southerly airflow across the state.
Today will be generally warm and humid with easterly
winds persisting, fresh
along the coast. Showers and thunderstorms are
expected today and are currently
occurring in the Mallee and northern Wimmera. Humidity
levels are generally
high. Estimates issued this morning look ok although
the LAL's in the Mallee
should be 2 instead of 1. A significant weather chart
will be issued shortly and
indicates thunderstortms possible in all parts of the
state and a severe
thunderstorm watch area is indicated in the northwest.
Sunday will be humid and warm with showers and
thunderstorms becoming more
widespread from the west and some locally heavy falls
are likely. Winds will be
mainly moderate to fresh east to northeasterly."
Chrissie dinner is going to be a quick affair this
year :)
Got the SLR and 6 rolls of film ready, will keep
everyone posted.

Well, it was always going to be a storm day here, with Cu popping up all
over the place from very early in the morning. After Christmas dinner, I
checked the radar at 2.00pm CST and it was obvious that east of the Mt
Lofties was the place to be, but there was also activity on the Northern
Adelaide plains. Because of the shorter distance and the flat terrain, I
opted to chase to the latter hoping to be on the northern flank if any
severe stuff caught up with me.
So I drove north to the west of Gawler. Lovely H-bomb and flanking line to
the NW. Didn't take a pic as it was right in the sun unfortunately. To
the SE was very black. I got my reward with a lovely guster passing
overhead. After that it was just light rain so I headed east over the Mt
Lofties hoping to intercept the next cell head on. As it was the idea was
right but the timing was wrong as I emerged on the Lofties eastern scarp
just to the south and behind a gorgeous looking cell that ended up bringing
quite bad flooding to the town of Eudunda. Nice base structure, inflow
bands and a beautiful leticular cloud were my rewards - but there was no
hope of chasing it from so far behind.
All in all, not a bad day, no real severe weather, but some nice shots
snapped, and it could have been so much better. What I really needed for
Christmas was a laptop and mobile phone connection! Santa????
Godd chasing to all, especially in western Victoria!
