Back in January I made a plea to severe wx website operators to
consider a permanent URL structure for their sites. I said, in part:

I would think that ASWA at some point will need to consider some means
of indexing and cross-referencing the wealth of information on severe
weather that is rapidly accumulating. In the meantime, I am keen to
place links to event descriptions on the relevant news pages of my
Australian Weather News. These are already indexed back to 1998, and
are in chronological order back to 1996. Cross-referencing like this
would at least achieve a simple indexing across reliable sites, and
make it available immediately.
I've set up a page at http://ausweather.simplenet.com/severewebs/ on
which I've started listing those sites with permanent URLs, together
with a brief description of their file structures. There are only my
site and Australian Severe Weather there at present to give some idea
of what's intended, but it could grow to be a useful working document
for all severe weather site webmasters who want to link with
confidence to other sites.
If you would like to become part of this, have a look at the page and
email me.

Yes, this was a case I did not discuss. When wall clouds form prior to the
development of rain it is again caused by the updraft tapping the contact
layer or lower region of the boundary layer where RH is higher, typically.
"Accelerating updraft" does not lower the condensation level. You may be
referring to something else that I am not aware of. However, the only
other way, as I understand it, is to do so by lowering the pressure locally
which is what happens in tornadoes. However, the storm scale pressure
depression at the base of the updraft is typically only between about 0.5
mb to around 5 mb (Hectopascles) in the more extreme cases. Depressions of
this magnitude are still insufficient to produce any appreciable lowering
of the cloud base.
Thanks for reminding me of the case I excluded!

Well, yes, you are correct, in the states we rate a tornado by its most
intense destruction anywhere along the path. The F-scale is a damage scale
and not really a wind-speed scale. The wind speeds assigned to the F-scale
are only rough estimates. We really don't know how accurate these are but
we have never believed them to be very accurate.

Hi Ira and all,
I nearly completed a reply last night, but Windows decided it wanted to
crash first...
It's certainly a valid point over how do we rate tornadoes using the
F-scale, and Les also brings up a valid point over should we still use
the F-scale.
Currently, the F-scale states that the entire tornado path is rated
according to strongest damage attributed to the tornado. So if 100
houses are damaged, 99 exhibit F2 damage, but one house exhibits F5
damage, then the entire track *should* be rated an F5. Whether or not
they decide to the discount the house is a different story. But you can
already see the problems with this. Not all houses are built in the
same way, sone are older, others a newer, some may have been built well
by reputable builders, other houses may have been built by shoddy
builders. You could look at the position of the house, and then see if
it was close to other houses, as you would expect the damage to be
fairly uniform over a row of houses. But if the house was isolated, you
might consider that the tornado strengthened considerably.
As you said, Australia uses an average damage path, and rates it
according to that. In my opinion, this is how the US should do it too!
It gives a much more accurate representation of the damage path.
However, it has to be something the entire world would use as a
standard, or it'd make global tornado studies a nightmare! The '73
tornado exhibited a mixture of F1, F2 and F3 damage, with evidence to
suggest F4 damage in some areas! But the track was rated a "high F2."
I don't see any problem with using "high F2" or "low F4" as a break up
term to assist in dividing the F-scale, but I believe some people aren't
too happy with that.
The 1992 Bucca tornado was rated an F4 as an average of the damage, but
importantly in the official report it was labelled "...at least F4
damage." I've only seen some photos of the damage, and it certainly was
good F4 damage, but I have a feeling that there was some uncertainity in
the report as to what type of violent rating it should have been
given...
I have also heard good arguments over whether we should just label
tornadoes weak, strong and violent. With the argument being it really
doesn't matter if the tornado is F4/F5 - the fact is, it's a violent
tornado! Similarly with F0/F1 and F2/F3 for weak/strong tornadoes.
While I agree the Torro scale is broken up more - I guess I'm like many
others, slightly old-fashioned and still likes the F-scale to an extent
and wouldn't like to see it go.
A formula could probably be derived through extensive studies to try and
convert F-scales, but it'll never be perfect. Similar to rating
hurricanes in the US, and TC's in Australia and the different wind
speeds they use. There are formulas to try and convert them, but
they're not always very accurate. Interestingly, the SS scale in the US
is meant to be for a 10minute wind speed average!!! (Or is it five
minutes?), anyway - over time, they've just been using a one minute wind
speed average! Meaning that they've been rating their hurricanes higher
than they really should have been. I must admit, I was almost happy to
here this - as I remember being blasted many a time by a some what
over-patriotic obnoxious yank for daring to compare out Cat 5 TC's with
their Cat 5 hurricanes! :) (PS, I don't mean to offend anyone here, and
certainly not our US friends on the list! Every US person on this list
has been extremely kind and helpful!)

Hi David,
It was certain impressive last night! A little too impressive actually
:) Townsville radar tends to overestimate a fair bit - quite a few of
the regional radars do. So the intensities can be made to look much
more intense. The best way to tell is by thinking "Does this look
real?"
On the other end of the spectrum, some radars under-estimate. Perth is
a prime example of this, and Brisbane also under-estimates.

The Fujita Scale was put forward by Fujita / Pearson in 1971, I believe. The
Torro Scale was proposed in 1972.... (:

Hi Everyone,
Just looking at the NGP model for Monday and it appears that we
may just have the right ingredients for some severe storms in E NSW. The
300mb prognosis indicates an upper level trough just skirting the SE of NSW
- although it doesn't appear to be very deep. Perhaps this is the one storm
chasers have been waiting for? If the dew points remain as high as they
have in recent days, there will be plenty of energy for any storms forming.

Even more curiously (and slightly OT) the Torro Scale can be used in place
of the Saffir - Simpson scale of TC / hurricane / typhoon intensity as it is
an extension of the good old Beaufort Scale....

Note, that in widespread precip, the C-band (~5 cm) radars will appear to
'underestimate' the intensities of all but nearby echoes as compared to
S-band (~ 10 cm) radars. This is due to attenuation of C-band radar.
C-band radars are about a factor of 10 more susceptible to attenuation than
are S-band radars. The more extensive or heavier the precipitation, the
worse will be the attenuation. Moreover, beam widths and pulse depths are
other factors to be considered. Finally the radar calibration is, of
course, a distinct factor as well.
As I am sure everyone realizes, these major factors mentioned above are not
the only factors but only the most important ones.

The one?? The last week has been pretty fantastic for NSW storm wise and it
looks like that will continue for the next 4-5 days. Don't know whether
you've looked at the AVN LI or other models, but the next 4 days look like
being great days with LI of -6 out west near Dubbo and Parkes. And Saturday
is shaping up to be great day for chasing in NSW with -4 to -6 enveloping
SE NSW. Monday is a long way off yet, and plenty of as promising stuff in
between.

Anthony and all:
Note that I did not wish to do away with the F-scale. I meant to only
mention that it was a damage scale and not a wind-speed scale. It really
can not be a wind-speed scale until we can accurately measure those speeds.
Moreover, it is not as if we here in the states disregard the structural
integrity of the damaged structures. That is factored in. However, the
F-scale is a very subjective scale and, unfortunate as it is, other factors
can affect the ratings such as experience of the one doing the rating or
biases of those responsible in the end for the final ratings. Texas Tech
University in Lubbock TX has a wind engineering department that will
sometimes send a team into a damage path when engineered structures have
been damaged. They will go to these sites and evaluate what was damaged as
well as what was not damaged. They will note what was moved and what was
not moved. They will also find structural components that have become
airborne and attempt to determine the trajectories these debris fragments
have executed and the time they remain airborne. However, we have also
noted, of course, that the surface roughness will affect local intensities
as will the amount of airborne debris. We have also attempted the use of
Doppler radar and photogramitry as means of estimating wind speeds. I have
been involved in using both those tools to estimate wind speeds as well as
numerous damage surveys. All these techniques also have their
limitations. Much goes into the ratings. I would agree with Anthony that
a mean intensity scale or damage scale is superior to the extreme along the
path. Yes, Australia, in my humble opinion, does it the right way.
To my knowledge we, in the states have never attempted a 5-minute or a
10-minute sustained wind estimate anywhere. We have always ranked tropical
storms by a 1-minute sustained wind and gusts during a 10-minute period. I
could be wrong but I believe this to be the case. In fact, in doing
comparisons of radar and other means of wind estimation I was always happy
that a 1-minute average was used because it was closer to what the radar
measured.

There is no doubt that there is a quite broad region of instability over
central NSW as there has been for a while. But the wind profile is very
ordinary so I assume that Paul is providing a supercell prognosis. Still, I
for one cant wait for Saturday as it is looking good for pulse severe storms
or perhaps multicells.
BTW your pics from earlier in the week were great. I went down to Camden and
saw that Richmond storm but dismissed it as it looked very low topped and I
wasn't detecting much in the way of static...a lesson learned I guess.

I've seen it reported several times in the 1990's. Perhaps 1918 is the

Unfortunately not - a pity because it had overshooting tops and the
works (and a perspective from 10,000 metres is always different to
that on the ground). I was actually taken rather by surprise, having
been away at a conference and not seen a proper chart for several
days.

Les,
I was thinking of a recent tornadic event in Central Victoria where the
enhanced updraft tapping into the boundary layer and surface layer which was
very dry appeared to erode a hole in a small wall cloud where the updraft
entered the wall cloud base (this was a rotating tornadic updraft).
Kind regards,
Clyve Herbert
Les wrote:
Yes, this was a case I did not discuss. When wall clouds form prior to the
development of rain it is again caused by the updraft tapping the contact
layer or lower region of the boundary layer where RH is higher, typically.
"Accelerating updraft" does not lower the condensation level. You may be
referring to something else that I am not aware of. However, the only
other way, as I understand it, is to do so by lowering the pressure locally
which is what happens in tornadoes. However, the storm scale pressure
depression at the base of the updraft is typically only between about 0.5
mb to around 5 mb (Hectopascles) in the more extreme cases. Depressions of
this magnitude are still insufficient to produce any appreciable lowering
of the cloud base.

The site was moved slightly (30m) in 1996 to get it away from nearby
vegetation. I would expect that the readings from the new site are
more representative, and higher, than those from the old site (haven't
analysed this in detail), but there is still lots of vegetation nearby
(inevitable at that location), so it is likely that the true rainfall
is even higher than what is reported.
Incidentally, I will be doing an investigation over the next couple of
months of all the major Australian temperature and rainfall extremes
(highest max, lowest min, highest daily, monthly and annual rainfalls
for all states). Hopefully I'll get the OK to put the findings on the
external web - will keep you posted.

As far as I know this failed to reach TC status, but has brought some
very heavy rain to the coast between Innisfail and Prosperine;
252mm at Ingham, and widespread 100+ falls.

There were media reports of 250-350mm in the Pambula River catchments.
I presume that these were from State Forests gauges (which I know
exist, because I did a study of the area in an undergraduate project
once), as no Bureau gauge recorded remotely close to this. The
severity of the local flooding does suggest very heavy falls, at least
locally.

Curious, given that Buenos Aires is at the same latitude as Wollongong
and the nearest elevation above ~50m is 100km away. I presume the
extra snowiness is the result of colder ocean currents, + the way lows
in winter tend to deepen more substantially once they get east of the
constriction of the Andes.

I suspect the additional continentality resulting from the extension
of the landmass to the mid-50s south is a more significant influence.
Further inland at similar latitudes in South America, winter
temperatures can approach American levels of variability, although
with a higher base; I saw a month's data from a SE Bolivian station
once (in July) which had maxima of 40 and 10 within a few days of
each other.

Today is proving abnormally hot in SA and Victoria. Numerous SA
stations are reporting in the 37-39 range at present (including 37
at Adelaide), although nowhere had got to 40 at last report. A lot
of late-season records could be broken (Adelaide's previous hottest
so late in autumn is 38.8 on 23 March 1938), as could some records
for latest-ever 40-degree day (13 March at Adelaide and 11 March at
Snowtown, for example).
Victoria is also hot (widely over 30, and up to 35 in places), but
this is not of record-setting potential, especially after Melbourne
got 38.7 on 22 March 1998. Melbourne's max so far is 33.0. If it
gets to 35, it will only rank 21st for latest date over 35 - one
needs to go another week forward for it to be a rare event (only
1940 has seen a 35-degree day later than March 25).
Melbourne's mean maximum for March is also running well above average
(27.4, compared with a monthly mean of 23.8). This won't challenge
1940's record of 28.9 (arguably the most exceptional monthly mean
in the Melbourne record for any month), but currently ranks 3rd, and
should give us another month in decile 10 (cutoff 25.5), even allowing
for it to drop at the climatologically expected rate in the later
part of the month. Unlike February, hot Marches have not been a
feature of recent years in Melbourne - there has only been one March with
a mean maximum in decile 10 (1985) in the last 25 years. The mean
minimum of 16.8 is currently running equal to the 1974 record, and
should come in in the top five. The monthly mean of 22.1 is also
somewhat above the existing record of 21.4 (1940, remarkably enough,
had a mean minimum of only 13.1, just above the climatological normal).

I am unfamiliar with anything like this. There are a couple of
possibilities that I am familiar with. I have seen wall clouds eroded
away by the RFD and not by surface air. The second possibility is that if
the storm overtakes dry air, as they often can do when they outrun the
low-level jet and the most tongue and support, you will see the wall cloud
simply appear to dissipate or "lift". And the storm will weaken and
dissipate.
But, what you describe, I have never before observed nor read of. It is
interesting speculation.

Suggestions please for a new humour web page being written for the MSC
site:-
Idea:-
things to do in Thargomindah when trapped by floodwater (bearing in mind
that you may be trapped for between 8 & 16 weeks as has been the case
recently)
All suggestions greatly appreciated, but to get you started, here are just a
few ideas to get you in the right mood:
* bindii - extraction kiosk (a 3 pronged seed that penetrates thongs, 1"
thick leather & tyres)
* buy drinks for the locals (guaranteed to pass one night)
* develop a smelling scale for the local water (how many of you have benn in
close contact with very old bore water????)
* encourage friendly competition between the 2 motels by consistently
checking out of one and into the other
* chat up the local publican's daughter because if you see the local
publican you'll be able to walk on water
* dream of going to Cunnamulla
PS: for those who have no idea what we are talking about, think of the last
place you'd want to be for 8 weeks ...........

VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON CURRENT SATELLITE INTENSITY ESTIMATES OF 30 KNOTS. ANIMATED
VISIBLE SATELLITE IMAGERY INDICATES A PARTIALLY EXPOSED LOW LEVEL
CIRCULATION CENTER (LLCC) EAST OF THE CONVECTION. UW-CIMSS ANALYSIS
SHOWS A VERY TIGHT GRADIENT OF INCREASING VERTICAL WIND SHEAR TO THE

Issued at 3:45 pm on Friday, 17 March 2000
For people in the West Coast east of Ceduna, Eastern and Lower Eyre
Peninsulas, Yorke Peninsula and the Northwest Pastoral west of the Stuart

As part of 2 bus loads of 16 year olds on a high school excursion we escaped
floodwaters further west during November 1989 and ended up being stuck at
Thargomindah for a several days (but long enough I can tell you).
So here are some ideas:
*Spend every last cent on the local pay phone unsuccessfully explaining to
your parents where the hell you are.
*Behold the beauty of the steaming toilet bowl (a result of the boiling
local water)...who needs Old Faithful.
*Discover just how many hours you can sleep in one day.
*Find a vehicle and do laps around town just so you can use the
air-conditioning (and if your are really lucky you'll find a coach and watch
a movie) - not too long though or you'll get dizzy.
Beware of these suggestions thought as our bus trip subsequently descended
into madness and I don't think my whole year of school were ever the same
again.

LOL!!!!!!!!!!!! very funny :)
Certainly a place that leaves lots of memories.. we were only there for 1
night... but the memories will live with us chasers forever. I cant imagine
what a few days would have been like!
Just got back from a storm chase as well, chaser convergence at Luddenham
where me, daniel weatherhead and max king met up. Nice little storm on the
ranges got progressivly closer and we then took off towards penrith, where
just as it was about to move off the ranges it died... should have a few
nice photos though.

Still looking the goods for storms tomorrow, but just to be certain leave
Sydney for Lithgow or Bowral.
LI's have been scaled down a little, but CAPE has been scaled up to 2000
just south of Bathurst.
Upper winds pretty poor though.
So what about tomorrow's meeting if there are chaseble storms ?
The models look similar for Sunday an Monday too.

Just a reminder of the NSW ASWA meeting tomorrow night. (And there is also
one in Victoria for the Vics)
Please be aware that some of us may turn up around the 6pm mark or so
because of chasing and that the meeting starts at around 7:30pm officially
this time around. Mario should be home regardless.
Just remember, the talk is on Supercells by Paul Graham.
See you all there.

My "best" was an air temp of 36 and DP of 28 in Darwin mid November 98, and
quite a few others close to that. I think a few days I spent in Kakadu and
Katherine the November just gone would've been close to that at least.
Probably higher air temp (39-40) and slightly lower DP 25-26 though. This is
a guess admittedly but all I know is that in Pine Creek I was in the hottest
weather I could remember - no breeze and clear sky - best storm I have ever
seen that night though. Half a dozen cells all going ballistic electrically
- awesome stuff :).
