Like with any index you can look at the Lifted Index the lazy way
(the more negative the LI, the better), or try and understand its limitations.

In essence the LI is the difference between the 500 hPa temperature 
and the (hypothetical) temperature of an "air parcel" that has been 
lifted to 500 hPa from (near) the surface (conserving its 
potential / equivalent potential temperature). 

A negative LI means that the hypothetical
air parcel is warmer than the environment, and thus buoyant.
"Hypothetical" refers to a bunch of assumptions included in the 
LI concept:  
parcel doesn't mix with environmental air,  
parcel is lifted from the surface (I think), 
parcel is lifted through all inversions on the way, 
the 500 hPa level might not be representative of a deeper
atmospheric layer ...

A more widespread measure of convective potential is CAPE
(Convective Available Potential Energy), as CAPE contains information of 
parcel/environment temperature differences through a deep layer.  

May the LI be low, and the CAPE be high,

Harald

Clyve is correct as I understand it.  Sleet is known as Ice Pellets or
"IP".  It is reported as such.  Sleet falls when the precip forms as rain
because it forms in atmospheric layers where the temp is above freezing. 
These rain drops then fall into a layer where the air temp is often several
degrees below freezing.  If that layer is of sufficient depth and is
sufficiently cold, the falling rain drops freeze and become IP.  (In
certain situations snow can melt as it falls through air that is above
freezing becoming rain and then changing over to IP as it again falls
through a cold air layer.)  These ice pellets will bounce upon reaching the
ground.  If it is sufficiently heavy and lasting sufficiently long, the
ground can become covered with these ice pellets, sometimes to up to
several cm deep.  They will be 5mm in diameter or smaller.  Normally, IP
occurs in an area where rain becomes mixed with IP as the temp falls, it
then changes to only IP, and then will become mixed with snow and the
changes over to all snow.

Yes, rain mixed with snow is just that, rain mixed with snow.  Another
"wintery" mix is rain, snow, and IP, all falling at the same time.  Again,
that is exactly what would be reported.  Sleet is defined as above, IP. 
When larger that about 5mm in diameter, when falling from convective clouds
accompanied by thunder and lightning, and when the surface temps are
appreciable (~ 5 degrees C or more) above freezing, then those large ice
pellets could be considered hail.  Here, hail in the winter months and in a
generally cold airmass is very rare.  Normally in this part of the world,
the only way we can get sufficient instability and sufficiently strong
updrafts for hail growth and fall-out is during the spring, summer, or fall
months.  These supporting airmasses are warm and moist having relatively
high dew points and temperatures.

Storm motion is the motion of the updraft area.  Storm motion is a
combination of "translation" and "propagation".  Translation occurs when
the convective cloud tends to move with the air-flow in which it is
embedded, that is with the cloud bearing layer winds.  Propagation can
occur discreetly as new congestus grow and merge with the storm on a
preferd flank.  The storm will tend to move in the direction of new
congestus development, that is toward that flank.  Propagation can also
occur "continuously" as new updraft is continuously generated on a preferd
storm flank.  

Sever storms will tend to propagate in either of these ways due to either
the interaction of the storm with the environmental sheared flow or due to
the tendency for the updraft itself to take on rotation. (The storms own
gust front or a mesoscale or synoptic boundary can also help induce new
updraft growth and will encourage the storm motion along the boundary
itself.)   When either of these dynamical interactions occur, the storm
will "deviate" from the direction of motion of the non severe storms in the
same environment.

Most often then, storm mergers are the result of one storm, often a severe
storm, deviating such that it collides with and merges with a non severe or
less severe storm.  If the precipitation area of one is drawn into the
updraft of the other, this process can actually kill the updraft and the
storm itself so only one updraft survives.  On the other hand, sometimes
the updraft of each can merge with the other and this process may then lead
to a stronger updraft and an even more severe storm.

> * hail breaking up *before* it reaches the ground?

This is usually the result of the fact that the hail is "mushy" or has a
large amount of liquid water within the ice.  When the hail reaches its
terminal fall velocities it may then begin to break up due to friction and
the "mushy" character of the ice.

I think one of the problems with LI, is that there are several different
ways of evaluating the theoretical (or hypothetical) air parcel plot
line.  Some take the strict surface measurements with no mixing, others
take the mean of the lower 100mb to base the DP/mixing ratio on - and
others go in between this.  The difference of this, is meant to be the
strict surface measurements are the SLI's, and the 100mb mean of the
DP/mixing ratio (ie, lowest 100mb of the atmosphere) is classified as
"LI."

AVN says it calculates SLI's, but really in actual fact calculates the
LI.  Wyoming and the BoM soundings are all plotted differently - so this
makes it difficult for anyone who isn't familiar with them.

I've seen many cases where there's a large (8-10C) inversion at the
500mb layer, resulting on strongly stable (+6 to +8) readings for the
LI, when 550mb and below are actually unstable still allowing for deep
convective showers.  In other cases, I've seen the opposite when you
have a thin cold layer at 500mb.  500mb is too arbitrary!  And also is
not enough to base the entire atmosphere on.

I'll try and get this page up on MSC...as you said, it's better to try
and understand the limitations of LI rather then using them as negative
= better.  It of course does not mean LI is a horrible index, on the
grand scale of things it's one of the better ones.  But maybe that
doesn't say too much of what I think of indicies :-)

I do like SRH and CAPE though, as they give an actual measure or
'something' (ie, area bounded by theoretical air parcel and ELR, and the
mean storm direction and area of the winds on the hodograph).  But even
they too have their limitations when used too loosely.

Hi everyone,
                  Pretty interesting weather pattern at present with the
cold spells.  The jetstream is around the 150 to 170kt mark!
EC is predicting another nice upper cold pool moving in next friday, while
GASP has a much broader system with the coldest air much further south.
NGP has something similar to GASP but the one feature is that they all tend
to agree that the pattern is for more of the same.

The black stuff might be a precipitation core (in particular if the sun
was shining at "bloke's" position).

Maybe the storm from the south was a "left-mover".
Maybe the cold pools generated by the storms present in the area
set up convergence lines in such a way, that the two storms 
(seen as *processes* rather than travelling unchanging blobs)
"developed" along those lines.
No one I know really understands storm-storm interaction all that well.

Hail that breaks up in mid-air sounds like mushy stuff to me.
My best guess is that these mushy hailstones contain a fair 
amount of water.  If you catch one of those in a net and put it into the
freezer,  the same hailstone would emerge rock-hard after a few hours
(depending on your freezer). 

Cheers,  Harald

Hey pples.....

I think what we all call winter hail (aka graupel) is this "IP" that Leslie
is talking about - the description is very similar to what we get down
south.  A lot of the winter hail I get here in Melbourne is from showers -
thunder is very rarely heard.  If thunder is heard I think the hail takes on
a bit of a different "look" to it - I dunno - maybe its just cause I get
excited when I hear the thunder....hehehe.

No, hail is hail.  Hail occurs with thunderstorms and is usually larger,
often much larger than IP (IP is normally less than about 5 mm in
diameter), as I explained in my previous post.  IP occurs in winter with
winter type airmasses and storms or showers.  IP (sleet) consists of frozen
raindrops or raindrops that freeze while falling through air colder than
freezing and that cold air is usually near the earth's surface.  IP is
normally not associated with thunderstorms as is hail.

Hi Paul and all

The Day 4/5/6 charts are manually drawn by the forecaster on
duty(yesterday's charts ie me), and thereby naturally take an input from a
number of models, including the forecaster's own
intuition/experience/whatever you want to call it. Generally, we make use of
GASP, EC and NGP to a large extent, but do not rely on one solely. For this
particular setup, EC and NGP seemed to be roughly in line with each other
out to the end of their runs, while GASP was not far off, although differed
slightly in its setup for the southeast. Both NGP and GASP provide precip
forecasts which can aid the forecaster in determining rain areas, but once
again, these are not used exclusively for these particular maps. In the
particular case you are talking about, that shaded area is probably to be
interpreted differently to a similar shaded area further south for example.
At this time of year, shower activity is very hit and miss in the tropics,
so that area represents more of a "possible area for a shower to form"
rather than the delineation of a rain band area, such as might be expected
in WA or VIC in winter for example.

Hope this helps

Matt

Jane,

Great attempt at humour from Ol Me'hico. But seriously though, should the T
and X-junctions read something like: multiple choices, any of which will
turn bust as soon as driven down, and activity on other choices will
accelerate away at an exponential rate with desperation to get back into the
chase.

Happy storm chasing from the region with the poorest road coverage. The
Illawarra escarpment.

You guys need professional help!!

But you did forget, School Bus Ahead: The Bus driver will notice the
Stormchasers coming at terrifying speed and pull over into this zone to
allow them to pass safely.

Note: But not this school bus driver. He will do all he can to beat you
there.......:-)

If my memory serves me correct that area had a decent jet stream, therefore

Hi Macca.
We had a shower here (i think 5 years ago in July) This large  cold CB moved
from the southwest, It produced occasional thunder but all the precip was
either snow pellets or small hail, air temp remained about 4c. Sea surface
temp over Bass Strait was about 12c, the lightning discharge was rather
uniform at about 1 discharge every 3min give or take a few seconds. After
the shower moved to the northeast a small mid level anvil could be seen
along the rear of the main Cb which was reaching to about 22.000ft . From
this mid level area snow was falling which actually reached  sea level, and
produced a few  flakes   here in Leopold.

Under the Bureau's new Basic Product Set, the following becomes free:

Observations for capital cities updated every 10 minutes
All other AWS observations updated hourly
Radar -- single frame and an animation of the three latest frames
Hourly state and national satpix at low resolution

In other words, not too far different to what The Weather Co has on
its site at present. 

Just when all this will be available is uncertain -- phasing in by end
of November is the best information I can get.

Hi Bussie.
Yep your right, the train windshields were all modified about 10 years ago
to be bullet proof after some goose started taking pot shots at drivers
around Laverton, interesting remedy!, as all the bullets came into the side
windows not the front windshield,and the side windows have not been
modified, in respect to bricks , a brick as big as your hand will merrily
smash a bullet proof windscreen into pieces and quite often with a huge
explosion, i have been in the cab with three transit police when a large
rock sailed through and hit the police sergeant square in the
forehead!....He required hospital treatment. but back to weather they will
stop golf ball size hail thats the largest i have encountered. regards Clyve
H.

The Bureau issues strong wind warnings when *average* winds of 22 to
33 knots (41 to 62 km/h) are expected over a wide area. I think the
definition of "wide area" is left to the forecaster. If winds of 34 to
47 knots (63 to 87km/h) are expected, they issue a gale warning, while
above this a storm warning is issued. 

So (1) it is average strength, not gust strength, and (2) warnings
aren't issued for strong local winds. Often ridge tops and certain
valley formations can induce stronger winds than over the wider area.
Squally gusts often happen on the leeward side of mountains, cliffs
and in some coastal areas, but unless the mean wind (which should be a
10 minute average) is expected to exceed the threshhold over a wide
area, a warning isn't issued. You can understand why if you drive for
a while in a moderate wind -- local effects can mean that the wind is
above the strong wind threshhold in isolated areas, but below
(sometimes near calm) in others areas. Gusts are typically 1.4 times
the average wind, but that can vary too.

An exception is gusty or squally wind near storms or a strong wind
change -- the Bureau sometimes issues specific warnings for these.

All this is off the top of my head, so I stand corrected on any
details :-)

MEDIA RELEASE - HEAD OFFICE

'Gold medal' forecasting for the Games

Sydney weather forecasts will become even more accurate, with an
enhanced ability to detect and predict thunderstorms and other severe
weather during the 2000
Olympic Games, when a new radar comes on line today. 

Sydney's new 'doppler' radar will be commissioned by Dr Sharman Stone,
MP, Parliamentary Secretary to the Minister for the Environment and
Heritage. This will be the
first time a doppler radar has been used by the Bureau of Meteorology
for forecasting in Australia. 

"This new $1.25 million radar, to be located at Kurnell, will enhance
weather forecasting in the Sydney region. Doppler radars used in the
US and Canada have led to
noticeable improvements to warnings of severe weather events such as
thunderstorms," Dr Stone said. "Built at an overall cost of $1.25
million, the radar tower is 22
metres high and allows a forecasting range of 150 kilometres." 

Doppler radars generate more information about rainfall and wind
patterns than conventional radars and assist meteorologists to more
accurately forecast thunderstorms
and events such as Sydney's southerly buster. 

"The new radar will be able to better predict wind shear, aiding the
safe operation of Sydney Airport. The radar is so sensitive that it
can pick up swarms of insects this will
have applications in rural areas in helping to track insect plagues in
the near future," Dr Stone said. 

The new Kurnell radar forms part of the Commonwealth Government's
extensive commitment to the Sydney Olympics, Dr Stone said. "$2.7
million has been spent by the
Bureau to ensure that the Sydney Games has the best possible weather
forecasting capabilities to cater for the hundreds of thousands of
athletes, officials and spectators
that will converge on the city during the Olympic fortnight." 

"A feature of the Olympic service will be the greater frequency of
forecasts. Along with the normal maximum and minimum temperatures,
predictions for temperature,
rainfall, wind and humidity will be made every three hours." 

The Bureau has supplemented its normal Sydney forecasting contingent
with an additional 20 interstate forecasters and staff for the Games,
while two forecasters from
Athens will see first hand how Australia's Bureau of Meteorology has
prepared for the event. 

"Today's commissioning of the Kurnell radar will give Sydneysiders
up-to-the-minute, accurate and reliable weather information for the
Olympic fortnight and well into the
future," Dr Stone said.

**VANTAGE POINTS DATABASE
I'm going to compile the Victorian chapter of the Vantage Points
Database as Dann is absolutely flat-chat at the moment so if you have
any good Victorian viewing spots, could you please send me the details
with the following information:

Name (if any)
Location (nearest cross streets / roads & suburb / town)
Map reference: either Melways or Victorian Country Directory
Pros & Cons
Direction of view
and any information you think would be useful and I'll start a page for
each area of Victoria.
and a photo taken from there if you have an image you can email me


**WEATHER: Melbourne
It's that time of year when we all start to get out a little bit more
(Macca's catching fish, Anthony's at the football in the wrong state ie:
NSW) - this afternoon was my first 200km afternoon drive for a while
(seemed like a good idea at the time <g>)  & I found myself in a new
housing estate to the NW of Melbourne - see the shot on the linked page
if you'd like a totally unreal look at Melbourne....there were a few
high based showers about the N & NE of Melbourne earlier this afternoon
& the plane spotters were all out at the end of the runway with their
thermoses.

Hi all.
One can say its about time i will look forward to the possibility of seeing
this device in action ,after all its tax payer funded, i liked the referral
in the media release in regards to tracking insect swarms!?,i would rather
see the tracking of the early stages of a rotating updraft take precedent,
lets hope all capital cities can benefit from the installation of Doppler in
each state soon.
regards Clyve H.

The Bureau has updated its climatic data on the web. I haven't had a
detailed look, but first impressions of the changes are:

1. The data on which the averages and extremes are based appears to be
up to the end of 1999 or early 2000 -- I can't find a reference to
when in the accompanying notes, but the station period given for
current stations states "2000". The old data was up to end 1995 or
1996.

2. There are about 30 additional stations in the new listing, as the
additional 4 years data has pushed more stations above the minimum 10
years required for inclusion. Around 1140 locations are covered. 

3. Mean 9am and 3pm wind speeds are the only additional values given
-- but the amount of freely available information is superb compared
with most other countries' web offerings.

4. All stations now carry the rationalised naming system the Bureau
initiated about 2 years ago, so locations are a little clearer to
understand.

All this comes with comprehensive lists and maps to find the place
you're after. Pretty impressive.

The Victorian Aviation forecast has gone into "modify frequently mode"
as it does regularly in late winter - early spring every year - last
time I listened to it on the phone (which was probably 1500 or so near
Sunbury), there was absolutely no mention about anything remotely
interesting except for a decrease in the 500hPa temp from -25C to -27C
on either side of the ridge that went through this afternoon, so this
update came as a bit of a surprise........

OVERVIEW: UNSTABLE W'LY FLOW. ISOLATED THUNDERSTORMS TILL 12Z, MAINLY
NEAR AND N OF RANGES.
CLOUD: ISOL CB 3000/28000 TILL 12Z, MAINLY NEAR AND N OF RANGES.

Hi all.
A very nice detailed  image of the approaching cold CB line moving through
the central districts of Victoria, this line has just passed through Geelong
producing 2 to 10mm/hour rates( 2015hrs.). An interesting feature on the
colour loop this afternoon was the wrap around cloud band  south of the low
near Tasmania ,which has now started moving due west and is now south of the
weak low presently approaching the south west of Victoria. Another feature
worth watching is a blotch of mid level cloud moving through southern SA.
all worth keeping a watch on.

at 1130Z (2100AEST)
seem to show an extensive but not deep infeed of moisture from the Indian Ocean
to the SW of Sumatra and middle level (?) cloud development in SA. Might make it
interesting over the next few days with moisture loading like that???? - it
appears (from the soundings across that part of the country) to be between
approx 700 - 550hPa (~10,000 to ~17,000ft) & with a low heading for us and
returning air from south of Tasmania..........??????

2226AEST - it's just started to rain in Bayswater.......
