Hi folks,
As far as my knowledge goes, this whole HP,CL,LP distinction is quite a
hazy area, and not really well understood. For a start it must be
remembered that all the evidence points to there being a continuous
spectrum of storm types, and that these classifications are subjective.
I've actually just read a recent paper on this subject by Rasmussen and
Straka (1998) in which they suggest that the formation of the different
types of supercells depends on the amount of hydrometeors ingested into
the updraft. It seems a nice idea, but its a bit too soon for it to have
bourne too much scrutiny as yet. To cut a long story short, in ideally
isolated storms, the storm relative (SR) upper level wind speed should be
the major distinguishing factor in storm type. LP storms should have
strong SR upper level flows which carry a lot of the hydrometeors away
from the updraft and prevents them being reingested into the storm. CL and
HP should likewise have lower SR upper level wind speeds. In support of
this theory they composited observations of the various types and this
seemed to support the idea.
If correct, this offers a possible explanation for the apparent propensity
for LP storms to form near the dry line. As the dry line is usually the
western most limit of convective activity (the furthest "upstream" of the
upper winds), only hydrometeors formed within these storms themselves are
available to the storms' updrafts. In other locations, there is often
other convection around (including "upstream") and hydrometeors from these
other storms may become available to other storms, leading to a higher
proportion of CL or HP storms.
As noted elsewhere, LP storms often evolve into the other types - some
authors go as far as to say that all storms have their origins as LPs,
even though they may only be LPs for a short while.
A lot more needs to be done in this area, but in my own mind, I can't
really see any reason why the proportion of LP type supercells in
Australia should be significantly different from the US.
Cheers,
Jonty.

Hi every1,
Hmmnnn...chaos theory vs. determinism...a knotty one!
Let's pause for a tick...
Both versions of existence would seem to be correct...for instance everyone
knows that a car travelling at 100 km/h will travel a certain distance in x
amount of time...but quantum theory makes it impossible to predict where any
given electron (or any other sub-atomic particle for that matter) in that
same car will be at any given time...hmmnn...
We seem to be dealing with (at least!) two different scales of determinism.
One which is inherently (Heisenberg) indeterminite, and one which is quite
predictable. I don't think that it is chaos theory that necessarily limits
our prognoses, rather our interpretation.
Yes, butterflies may well change the car's path, but ultimately, once the
car is going, we may well have an idea.
Hmmmnnn...seems we have to find out JUST WHAT THAT BUTTERFLY DID!
Cause and effect...(well at least I still believe in causality..)
Just my musings...

Hi Jonty and folks,
I do agree with some of your points here. A great post! Especially the
hazy distinction in HP, CL, and LP. There is entirely too much
subjectivity in the distinction. You also must remember, this comes from
someone who was a co-discoverer of the LP (along with Davis-Jones and
Burgess)!! LOL Funny that you should mention the '98 paper by Rasmussen
and Straka. I am on a student's graduate committee at OU with both these
mates and his topic deals with just this subject. In fact, a couple of
weeks ago I met with the student and reviewed his thesis prospectus. He
hopes to perhaps better and more objectively define supercell types,
especially the HP. He heavily bases and references his thesis on the paper
you mentioned and one other that also deals with the effects of storm
relative flow. Moreover, three days ago at the AMS annual meeting, Chuck
Doswell and myself spent three hours discussing this distinction, the
existence of my "Deep Convergence Zone" (which may well define the
structural difference between "Classics" and "HPs") and such things as
storm vortex motion via vorticity advection. I have put much thought into
these topics recently. In fact, I can see another Lemon and Doswell paper
might well result. At least I hope we can do put another together.
Before the series of papers on these three supercell distinctions,
supercell definition was strictly based on Browning and his three
dimensional reflectivity structure. These discriminators left no room for
doubt. But this subclassification leaves much room for doubt due to the
great subjectivity in these definitions. I keep asking the question if,
indeed, the greater or lesser distribution of low-level precipitation does
point to a significant and real subclassification or whether this is a
figment of our imagination. I was on the verge of arguing that this really
was not significant and that this subclassification was inappropriate. It
was going to appear in the last Tornado symposium, but I opted not to write
it. Ever since I have wondered if that was the correct decision. I guess
I will never know, but I do believe we will relatively soon find real
answers to this dilemma. In the meantime, apart from the DCZ and the LP
(for obvious reasons, LOL!), I remain skeptical.

As far as my knowledge goes, this whole HP,CL,LP distinction is quite a
hazy area, and not really well understood. For a start it must be
remembered that all the evidence points to there being a continuous
spectrum of storm types, and that these classifications are subjective.
I've actually just read a recent paper on this subject by Rasmussen and
Straka (1998) in which they suggest that the formation of the different
types of supercells depends on the amount of hydrometeors ingested into
the updraft. It seems a nice idea, but its a bit too soon for it to have
bourne too much scrutiny as yet. To cut a long story short, in ideally
isolated storms, the storm relative (SR) upper level wind speed should be
the major distinguishing factor in storm type. LP storms should have
strong SR upper level flows which carry a lot of the hydrometeors away
from the updraft and prevents them being reingested into the storm. CL and
HP should likewise have lower SR upper level wind speeds. In support of
this theory they composited observations of the various types and this
seemed to support the idea.
If correct, this offers a possible explanation for the apparent propensity
for LP storms to form near the dry line. As the dry line is usually the
western most limit of convective activity (the furthest "upstream" of the
upper winds), only hydrometeors formed within these storms themselves are
available to the storms' updrafts. In other locations, there is often
other convection around (including "upstream") and hydrometeors from these
other storms may become available to other storms, leading to a higher
proportion of CL or HP storms.
As noted elsewhere, LP storms often evolve into the other types - some
authors go as far as to say that all storms have their origins as LPs,
even though they may only be LPs for a short while.
A lot more needs to be done in this area, but in my own mind, I can't
really see any reason why the proportion of LP type supercells in
Australia should be significantly different from the US.<

Phil, Dion, and all:
Yes, these shots are incredible! This is why I recommended sometime ago
that you all order "May's Furry". Actually 46 were killed, five indirectly
and the rest directly. It is truly amzing that hundreds were not killed!
We had a two hour session concerning the OK tornadoes at the AMS annual
meeting that just concluded in Long Beach, CA. There was also a special on
paramedics that just happened to be filmed in OKC during that storm. If
you get a chance to see that, do so. Here, I saw it, I believe, onTLC.
As I believe I mentioned here earlier, as I watched the radar in real-time
and knew what was happening, I actually had tears in my eyes. I knew
people were dying and I feared so much for all my friends in the area.
Each time I see May's Furry I feel almost the same way. Keep in mind that
this has been my business for 30 years and I have seen many tornadoes. But
the awesome nature of this and so many other nearby tornadoes that night
was simply overwhelming. I have recommended to Jane that she purchase the
video and show it during an ASWA meeting. I only wish I could be there to
fill in some detail and to watch it with you all.

Hey all,
My family home in Riverton (Southern Perth suburb) recieved large hail at
about 10:50am yesterday. Mum said that it totally covered the lawn and
during the hail storm cars were pulling up in our driveway to shelter under
the trees from the hail so it must of been BIG! :). They also took pics and
saved heaps of the hail in the freezer for me to see next time im down. I
have radar of the storm when it moved through the southern suburbs, it was
pink when the hailstorm hit Riverton... u can find the loop here....
http://www.kisser.net.au/kevans/weather/radar/hailstorm0150-0400utc.gif
Radar shows the storm developing and as it dissapaited. Local time
9:50am-12:00pm WST
I also saved images from the perth web cam which ill make into a movie soon
and ill also upload pics of the hail as soon as i get them sent to me from
Perth :)
Regards
Jason

Hi all,
Well - this movie had been bugging me in the video store for a few weeks
now, called "Storm" - on the back it says the Government is trying to
develop a way to control hurricanes...yada conspiricy yada...and they
finally develop it, but it goes horribly wrong when they lose the
weather controlling device in a tropical storm off Mexico. The storm
then rapidly develops into a Cat 5, that is on a direct course with Los
Angeles.
I was due for a "free overnight video" - so instead of me choosing one
of the expensive block buster $7/night hits...stupid Anthony had to go
and choose the $4/night one about weather (despite the sensible part of
my brain advising me NOT to hire it!)
Besides the incorrect factual information, the poor acting, and the poor
development of the plot in the first half of the movie, the second half
is OK, with at least a hint of a plot present.
But for those who picked Twister to the bone the way they portrayed
tornadoes, would have an absolute field day with this!
A few of the more obvious errors were:
- You do not refer to entering to the hurricane as "we're entering the
front"
- Global warming does not result in the "El Nino Effect" - in fact, even
if they did say "greenhouse effect," it'd still be wrong! As the
greenhouse effect results in global warming...not the opposite!
- Even if we could control weather, a tropical storm does not form into
a Cat 5 hurricane in 10 minutes.
- A TC doesn't move 600-800km in 6hrs (although some extra-tropical TC's
have moved in excess of 100km/h, they are somewhat different, and
certainly don't accelerate to 100km/h instantaneously!)
- I've seen better radar of a line of congestus showers than I have from
a "powerful tropical cyclone" that had no organised rotation whatsoever.
- Lightning is not continuous (5-6 flashes/second) in the eye wall of a
hurricane. In fact most hurricanes have had very little lightning
detected in them from lightning detectors. Though there have been a
handful of exceptions.
- A reporter would not be able to stand up in 150km/h winds (unless he
went to the gym for 5 years beforehand!)
- Having Luke Perry star the main role...isn't it obvious he simply
cannot act!?
