I think the earthing strap for your mast is what saved your house from going
up in smoke......my mast is bolted to a piece of pipe which is buried 3 ft
down..........another thing to worry about having radio's etc. still
connected to antenna's when lightning's about is a bolt landing close to the
house (or whatever) it can send a surge down the coax & rendering what's on
the end of it as what they call it in the trade is "being f****ed"
I haven't had that happen to me ....yet.......but having a 8m mast & a 5.5m
C.B antenna on top could be asking for trouble.......
John from Ballina
P.S Keith, how charred was the coax cable after the strike.....the reason
I'm asking is that I've heard different stories on what damage lightning
does to coax cable...thanx

Hi Jane, hi "List",
I am a new face on this list, and that's why I shall bore
you with some of my details.
As the trailer to my emails sate, I am currently based in Albany, NY,
attempting to use a mesoscale model (MM5) in the search for answers
on how thunderstorms form. Of particular interest to me is the
initiation of convection along so-called "drylines" - near-surface
boundaries separating high dewpoint from low dewpoint air.
One thing that would interest me a fair bit is evidence for
the existence and storm initiation role of those drylines
in Australia, particularly in NSW and QD. I have a funny
feeling that a number of the big storms there do actually
fire off the dryline. You can get special chaser satisfaction
out of observing those storms initiate on such a boundary, and
then monitor them for hours as they move E (NE,SE) and
develop all sorts of features, if you're lucky.
Why am I on this list? I lived on Melbourne
for almost all of this decade, and plan to return
after spending some more time with the National
Severe Storms Laboratory (NSSL) in Norman, Oklahoma.
I could post some of the chase experiences I might have in
the US, but as that is not Australian weather it would
be off topic, right?
Lots of CAPE, Harald

Hi Jimmy,
Quite similar to the Gold Coast house eh. Just shows what it can do. My
guess is that once again, lightning directly struck the house wiring at
some point (maybe at the meter box) as a way of getting to the best Earth,
which in this case would apparently have been at the dam, using the wire to
the pump as the conductive path. With a sufficiently intense storm there
may also have been more than one strike in the vicinity. One also should
remember that conductive material close to a strike obtains a huge induced
voltage due to the EM radiation. This is itself enough to take out any
connected electrical equipment.
John.

Ok my turn re lightning damage.
I can say at first hand that my parents have a farm located at Wyee which
was damaged one time from a lightning strike.
In August 1992, there was a dry day when although thunderstorms developed.
One of the storms came through undetected at Wyee by the locals (we weren't
there). Well, this storm produced a powerful lightning that left in its
wake a series of destruction. First, all windows on one side was shattered
facing the sonic boom created by the lightning (thunder). Every power point
was damaged completely and set on fire. Every electrical appliance was
damaged or burnt even though the main power was switched off at the fuse
box. By the way the fuse box lid which was locked with a pad lock was blown
off completely. The underground wiring leading to a pump of the small dam
was destroyed and the soil along the this wire was lifted to reveal its
location. Some of the fibro were cracked and the nails loosened and in some
cases has burn marks near them I think on the currugated iron sheets. The
PVC sewerage pipe we found a year or so later was shattered. A piece of
tile near the tap exploded into the air bouncing off the celing and then
onto the wall on the other side damaging a painting...
A tree near the house which may have been struck went brown but recovered a
month or so later. For months after the event, locals complained of not
being able to earth electrical fences... The telephone wire along the whole
road had to replaced. Yes, the transformer on the pole out on the road was
also damaged or destroyed.
To sum it all up, the electrical authority and electricians said they had
never seen this much damage in the many years dealing with their job!!!
Michael Bath has seen the damaged switches etc... I may bring it along to a
meeting some time.
Now had the people living in the other house (which was also damaged) not
acted quickly, the house would have caught on fire as well as the
electrical switched were on fire near the carpet...
By the way, people in the town 2 km away shit themselves with the sound of
the loud thunder...

There is no easy answer to this one! What I was saying that a scale of wind speeds based on
purely damage alone has to be flawed!
The TORRO scale is an extension of the Beaufort Scale, which is a measure of wind speed and
the consequent damage it causes, not vice versa!

Hi all,
After my comments yesterday about what the NOGAPS model was suggesting for
SE Aust for today, it seems that I am unlikely to be able to put the model
to any further testing.
Unless I have missed something, it looks like our part of the world south of
30S has been dropped from the display panels usually found at
http://www.fnmoc.navy.mil/wxmap/web/index.html.
I would appreciate a post from someone on the list telling me I am wrong -
otherwise it would be good if all of us who use the FNMOC models can send an
email asking them to reinstate the full Aust/NZ (which included WA) panels
that were discontinued in April this year.
I along with some others did email FNMOC earlier this year and didn't get a
response but I guess this is where persistence has to come into play.
Below is an extract from part of the WXMAP site which offers hope of more
areas at some stage subject to the usual constraint of resources...

Hi All,
Some time ago there was a question on how much water was required for
different crops - related to a question on winds picking up moisture while
passing over cropping land.
Original message was from Anthony Cornelius, 24/07/99.
On the 26th, Anthony asked :
>Does anyone have any exact figures, or know where to get figures on how
much
>water different types of vegetation emit?
Found these in a 1968 published book - Sun, Climate and Life by J Gentilli -
in the section on moisture budgeting and evaporation. Have added some
calculations of my own for sugar cane. Although they do not answer the
specific question, I thought they may be of interest. Haven't converted from
imperial, but 4.546 litres per gallon.
Product
Gallons required
1 man's woollen suit 224 000
1 pound scoured wool 120 000
1 pound beef
11 200
Daily dietary supply - 1 person 5 800
1 gallon milk
3 300
1 small fowl
3 300
1 pound rice
330
1 pint beer
300
1 pound bread
280
1 egg
220
1 orange
110
My calculations (average for Australia for a 100 ton per hectare crop)
1 ton sugar cane
30 000
1 ton sugar
220 000
The range (per ton cane) across Aus is from 43 000g in the Ord, WA, to 24
000g in SE Qld/NE NSW - largely radiation dependant.
On a per day basis, a sugar cane plant will transpire moisture at the same
rate as evaporation from an open water surface (Class A pan). However, the
relationship falls apart if winds get above about 25 knots as the plant's
protective mechanisms reduce water loss under such conditions. This
situation accounts for considerable loss of potential growth during cyclonic
conditions where constantly high wind speeds are sustained for long periods,
sometimes 15 to 20 days. For instance, Proserpine's annual evaporation is
around 2000 mm, but crop water use around 1500 mm.
Useless info - probably - there's plenty of it around !
Regards
Bill
Proserpine

*sigh* I wish I could tell you that you are wrong, but you are correct.
Australia from below 30S has been cut off the map. It seems that once
again Australia has been given the short end of the stick. FNMOC does 9
maps, and the US is not in 1, not in 2, not in 3, not in 4, but in 5 of
those maps!

I too emailed them, and had my email rudely ignored. What I am hoping,
is that they're updating, and they're going to put the old Australia &
NZ map on.

It is possible to still access the Australian panels. They are still there
but are hidden from the interface. Use you old URLs and you will find the
Australian maps that were discontinued in April this year.

Jimmy Deguara's email to Paul reminded me that I hadn't yet introduced
myself.. so here goes..
Anyway.. My name is David Jones and I live in Box Hill (at about 100m) some
15km east of Melbourne's CBD.
I currently work in the Climate Analysis Section of the Bureau of
Meteorology, and have been a Bureau employee for nearly 5 years. Since
joining I spent a year training to be a forecaster, 2 years in research, 2
years in climate analysis, and 10 weeks in hydrology.. I joined the Bureau
after completing a science degree majoring in meteorology at Melbourne
University. At work, my interests are primarily in the area of seasonal
prediction and monitoring of surface temperature, and the general analysis
of meteorological variables (particularly rainfall, and temperature). This
also includes the description of climate change..
Outside of work, I like to ski (X-country and downhill), snowboard, bush
walk, and boggy board.. I would profess to being a bit of a weather nut,
having taken obs since I was ~12 (BTW we had 102mm in August). Hate to admit
it but I am now 30... BTW I am also treasurer of AMOS and am keen to improve
links between our organisation and ASWA..

Hi Kevin - of course I have no technical thoughts on the matter, just want to say that your concept feels absolutely correct. You just need to look around -so many results are dependent on other phenomena.

Hey everyone,
I was up at Falls Creek this past weekend and they have had heaps of rain
over the last week or so washing away a lot of the cover. Warm
temperatures have also not helped with the overnight temps not getting
below zero so as to freeze the slush which has formed by the end of the
day. Melting at about 8-10cm /day at the moment.
In terms of more snow - the next cold front due down here in the SE of the
continent looks to be prety beefy in that it should give the alps a decent
dump of snow to hopefully keep the season going for a few more weeks.
THickness looks to be below 536 for a few days (sunday and monday) and this
along with plenty of moisture should see somewhere in the vicinity of 30cm
of fresh snow falling at the Victorian restorts. I'm not too sure how it
will go in relation to the NSW resorts but I think they could expcet a
similar amount.

Dean - the Ballarat Courier is a local paper which was around in that era. It bought out the BAllarat Star,of which my Great Grandfather was Editor.. There is also a very active Ballarat Historical Society which would keep records of phenomena such as this. If no other authority has details, copies of old newspapers are on microfilm at the State Library (Vic), and possibly some local libraries.

Hey Harald, Everyone..
Welcome to the list Harald..
Funny you should mention the MM5 model.. I stumbled upon it a few weeks
ago.. and after i inquired about it further i got the email below.. I
haven't had the time to look into it much further, but it is in the
public domain.. and it's a global model, so i figure it has forecasts
for Australia.. Maybe someone else will get the chance to get it all up
and running.. I have pasted the email below..
BTW, I like what the models are doing with this next front + trough for
the eastern states late this week/over the weekend.. MRF is showing good
potential for storms in SE QLD and other patrts of the eastern states..
*****************************************
Dear Mr. Quinn,
You can find much of the information on MM5 from the MM5 home page
(address below). MM5 modeling system software is in the public domain
(please see the 'Public Notice' on the side frame of the home page),
and any interested person may download it. You may be also interested
in seeing many of the MM5 real-time forecast sites:

The New Zealand weather service has recently started to run MM5
operationally.
If you have further questions, please contact me. Thanks for your
interest in MM5.

Morning All,
Since it seems to be the fashion. I had better introduce myself as well. Many of
the Melbourne people would have met me our last ASWA meeting but for the benefit
of everyone else....
My name is Peter Corlett. I have had an interest in severe weather, and a
corresponding lack of common sense, from an early age - I used to lie on my back
in the road to watch the lightning. I have a degree in Earth Science (ie.
geology and geophysics) from Monash Uni during which I managed to take some
units in Atmospheric Science. After 6.5 years in the Mining Industry I have
finally escaped and I'm currently working for the Victorian Government as a GIS
guru.
My interest in storm chasing per se was encouraged during my time as a tutor at
Roberts Hall by the Senior Tutor at the time, one Harald Richter (who has also
recently joined the list). Unfortunately, the storms during Harald's time in
Melbourne were pretty lame so we didn't chase all that many. Still, if the
weather is fine there's always geology (right, Harald?).
My other hobbies include cooking and swimming - the effects of one almost
balance out the effects of the other!
Cheers,
Pete.

Hi All,
Got this from our IT bloke. Can only assume its validity, but thought you'd
like to know.
>There's a new virus called Toadie which is attaching itself to e-mails and
executable files. If you receive a file called "FUNNIES.EXE" in your
e-mail, delete it, that's the virus.
What it does : Toadie is a fast infecting file virus which infects a large
number of .EXE(executable) files each time the virus is run. During
infection, Toadie copies the first section of the file, inserts itself into
the start of that file and then appends the copied code to the end of the
file. It then rearranges the file pointers to make sure the infected file
works for a given amount of time. What that all means is that the virus has
to potential to keep replicating itself on one file, which, in theory, will
slow the computer down dramatically.<

A very interesting thread - about lightning damage...a few
observations to go with it...and a good link...
http://thunder.msfc.nasa.gov/primer/
When dealing only with CG-lightning...
1) Lightning will find the most conductive path to/from Earth.
If that involves jumping a mere 2mm gap in a power switch, then
bye-bye switch. The power involved is more than enough to demolish
the entire electrical system in the average Australian house.
See above link.
2) Most damage to mains-connected appliances comes from CG strikes
quite a long way away. A "spike" propagates in the electricity
transmission cabling, often quenched to a degree by step-down
transformers (if their protection works and they survive) until
it reaches the 415V 3-phase consumer distribution network. At this
point, the consumer can install a "lightning arrestor". This is a
bad name for this device. A better name is "surge arrestor". It
would be useless against a direct CG strike on the house wiring
but quite OK for spikes on the incoming mains.
3) Other appliances such TV's can get damaged if their external
antenna's are directly hit or a CG strike occurs nearby. It is
best to incorporate a suitable "spark-gap" style of arrestor
at the splitter in the roof with a decent earth strap connected.
It will keep the induced spike from nearby CG strikes to within
your TV tuner's and splitter's manageable limits. The new earth
strap goes nowhere near the "earth" provided for your mains
power. Again, a direct CG-strike on your TV antenna will destroy
everything.
4) Telephones (not mobiles:-) are another susceptable device,
particularly if aerial cabling is used. Spikes can also be
induced from the telephone exchange but most of these are
caused by line-card failure, not by lighning-damaged exchange
power distribution. Underground cabling is susceptable if CG
lightning conducts through the earth breaking down the insulation
on the cables and also if remote above-ground repeater sites are
struck by CG lightning. Again, there are suitable arrestors
available for exchange-connected telephones and modems.
5) The cable-TV network is another potential source of damage
but there is a better sacrificial network usually installed
with it - consumer mains power distribution. See 1) above.
In summary, CG lightning can cause an incredible range of
damage from modems that exhibit some form of intermittant
problem and TV tuners that are not quite right to complete
destruction of all wiring in a house and even considerable
structural damage. Just imagine if CG lightning hit a metal
roof with metal framing tied down to reinforced concrete
columns via the reinforcing metal itself. Try dissipating
10,000 megawatts of direct CG lightning "up" that path and
you'll find that the concrete columns will probably blow
apart!

Looks like a strong cold outbreak for southwest WA on Friday - I see a
thickness level of 528 cutting across the southwest tip. Maybe a white
dusting for the Stirlings.
A fine, sunny day for Christchurch today, but still cool (about 9 C at
noon) after a morning frost. Yesterday's cold southerly was pretty
insubstantial - just some light showers.

The URLs include the date, which makes things a bit fiddly. I use the
attached document --
1. Open in a simple word processor like notepad or Wordpad
2. Globally replace the appropriate portions of the date (e.g. change
3100 to 3112)
3. Save as plain text
4. Open that file in your browser.

Hi Andrew,
In my experience over the last 11 years of visiting our Snowy
Mountains in late Oct/Nov almost every year, we have made our
"spring" opening of the lodge to friends/family later & later.
Only because of doubtful road access to our club lodge in
Perisher Valley for heavily-laden families. We started in 1988
with week 4 of Oct and were repeatedly snow-bound in 1989 and
1990 needing chains to get out of Perisher Valley (not on the
sealed road though). Another mob tried week 1 in Nov in 1991
which was OK (we were overseas). In 1992, we had to walk 100m
to the lodge over heavy snow drifts. In 1993, we were again
snow-bound by a 40cm fall. In 1994, we managed to drive out
while it was snowing before it really dumped. The work-party
that followed where snow-bound by nearly 80cm that blocked
all roads for 5 days. What a great excuse for missing
work! 1995 was clear of snow. We moved to week 3 of Nov in
1996 with good access. In 1997, a fall of wet snow froze
solid making roads impassable until the afternoon of our
departure. 1998 was excellent weather for bushwalking.
Now "our long weekend" in 1999 has been pushed forward to
week 1 of Nov as the directors have booked week 3. They
did this because of access problems in other years. So
fortunately, I have to disagree with you about "winter's
last laugh". It might be so for lower areas but up in the
mountains, winter has proven to just keep on laughing well
into November. Now I'm yet to be snow-bound in January but
last year, the mob who booked the Christmas period ended up
with a "white" Boxing Day. The kids (and adults) simply love
these occasions but it can a real pain as 1994 clearly shows.

Hi Laurier, Mark and all...
Thank you very much for the information on NGP! And as much as I
appreciate it, I have to raise one little point! :) May I suggest that
if anyone ever finds little things that if you:
a) Fiddle with numbers/the URL you get more info for AU
b) Find a new model for AU
c) Find more info that will help the general users on aussie-weather
That you PLEASE inform the aussie-weather list!!! So that others can
use it, as I know there's lots of users on here that were dissappointed
about AU being taken off the menu on the FNMOC site...and who will be
glad they can now access NGP again!
Just a thought/suggestion to anyone else out there who has info! Even
if you think other people know about it, there will always be people out
there who are new, or don't know about it! :)
Thanks, :-)

Yeah, I would have loved to have the NGP models all winter, we missed out
last winter because the PCMDI webpage went down which had the NGP, then
FNMOC took over during the summer and went down again before the winter.
Now its the 1st day of spring, and I find out the NGP has been around all
winter:)

Hey Anthony, Everyone..
I have to agree with Anthony here.. There must have been 40 or 50 emails
to this list about the removal of the Australian NGP.. for others like
myself who spend many hours a day following the models, not having NGP
was a big disappointment.. I can say that if i had found a way to get
the NGP maps the first email i would have written would have been to the
list..
Don't take offense to this email Laurier/Mark.. But i am just a bit
confused as to why it was kept quiet for so long..

I was not aware this wasn't common knowledge. I guess it's a new twist
on the old "I don't know what you don't know" problem, which is
exacerbated by the fact that I don't know what I miss when I hit a
busy patch at work and only have time to skim the (often misleading)
subject lines of postings.
It's one reason why I started my Australian Weather Links site three
years ago, so as to try to organise all links relevant to Australian
weather in the one place. I hadn't added the FNMOC Aussie panels to
that list because of the impossibility of direct linking, the
complexity of describing how to access the files, and the availability
until yesterday of a reasonable alternative. There is also FNMOC's
obvious reticence in making them available to be taken into account --
if they are in fact available by error, publication of the fact would
likely lead to early rectification of the error and loss of charts.

As far as I know the coax wasn't damaged, but whether that's because the
top 2 inches of the aerial were fried I don't know. I presume the charge
came down the coax and went back out via the anemometer then down
through the earthing cable..

Geez guys give us a break!!
I did see the emails back in April and saw the problem 1st hand but I was
travelling at the time. I even sent a mail to FNMOC and received no reply.
However, once I returned I tried our PC in the office and it was fine. We
just assumed that the problem had been fixed. All our PC's have had NOGAPS
bookmarked since October last year and have never failed. Since we link
directly to the image, we don't notice when FNMOC change their front menu.
We use NOGAPS every day as it is our favourite guidance for producing the 7
day city forecasts that we supply to Network TEN. If it were to vanish, then
we would certainly notice very quickly.
So sorry for all you who feel jilted by our silence. We were not aware there
was a problem,
Cheers, Mark

I have just received word about a supercell that occurred on the fateful

cell was described by the people who live at Oakdale to the SW of Sydney
near Camden as having monsterous hail lasting 20 minutes completely
shattering windows, deeply denting corrugated iron roofs, and their son was
knocked unconscious by a hailstone!!! I will gather more information on this.

Has anyone noticed the bizarre spinning upper level cloud around

radar at around 4pm.......
It appears to be virga actually affecting the radar there.....I visually
saw a band of it tonight at 6pm travelling southeast from Lismore to home
at Evans Head. The virga was to the west southwest of Lismore. Looking now
at the BOM analysis chart there appears to be an upwelling upper low ahead
of the accluded front....any spotters?????

One of the advantages that the New England area of NSW has that if storms
don't fire you can always go fossicking. A bit off subject, but there is an
old mining area about 20kms east of Glen Innes called Kingsgate ( probably
gets some great storms as it is on the escarpment but chasing would be
impossible ). There are several old shafts in the area that mined quartz
veins in granite for Molybdenum ( spelling ? ). Even today there are bits
and pieces of broken crystal laying around that once must have been points
2-3ft long. Finding a intact crystal of any size is now rare. From a book I
read some of the mines had to blast around quartz crystals a metre long.
With today's new age stuff all the rage I think it would turn a tidy profit
to reopen one of these mines specifically to mine crystals.

Bills E Mail is a good warning, do not run any .exe.com.bat ( or MS word
macro ) attachment to E Mail from an unknown source.
On the other there are a number hoax E Mails, How to give a Cat a Colonic,
You have won a holiday, etc. these are just chain mails.

Hi Harald
It is a pity you missed our sea breeze discussion a few months ago. The sea
breezes role in storms was hotly debated. There is no doubt that the
seabreeze front influences storms in both states.
Perhaps not a dryline in the US sense but often we get a NW wind pushing
ahead of front, typically September - December. On the coast the NE sea
breeze usually overpowers it. I have noticed time again that the best storm
activity occurs as the NW wind finally pushes aside the seabreeze. It is a
dual edge sword though as nothing ever forms behind the NW wind.

Hey Halden, Everyone..
There is actually an upper level trough moving across the region at the
moment and will effect SE QLD and Central QLD over the next 48 hours or
so.. but it is far from an upper low..
I'm not exactly sure what you are seeing there.. but i have seen it many
many times.. They are definitely ghost echo's..
On a slightly different subject.. I think we could see some nice
vertical development in Brisbane late tomorrow and Friday (if the cloud
stays away) with the passage of this upper level system.. I hope so, we
all know how storm starved us SE QLD'rs are

Hi all,
Well, both June and July have been above average, and August has been no
exception! Thanks to the thunderstorms a few days ago, I recorded
72.2mm, which is well above the average of 41mm. We're now into
September (spring, YAY!!!!!!!!!!!!!!) which is our driest month of all
(on average) with 33mm.
How have our NE NSW counterparts faired?

Hi Benn, and others interested in MM5,
It sounds like MM5 is run operationally in New Zealand
only (Wei, the primary MM5 user support person, would probably
know if someone would run it seriously in Australia).
MM5 is a mesoscale model, and the NZ version *might* cover
parts/all of Australia.
If you're keen you can download it yourself from the
website below. It would take some time to feed the
data into the model correctly if you don't have access the the
NCAR Mass Storage System where it is all set up already, but
in principle MM5 is quite user-friendly and easy to run.
Maybe one day I'll get the chance of implementing an
Australian version - that will possibly depend on the future
BOM funding and priorities.
s y later, Harald
Hey Harald, Everyone..
Welcome to the list Harald..
Funny you should mention the MM5 model.. I stumbled upon it a few weeks
ago.. and after i inquired about it further i got the email below.. I
haven't had the time to look into it much further, but it is in the
public domain.. and it's a global model, so i figure it has forecasts
for Australia.. Maybe someone else will get the chance to get it all up
and running.. I have pasted the email below..
BTW, I like what the models are doing with this next front + trough for
the eastern states late this week/over the weekend.. MRF is showing good
potential for storms in SE QLD and other patrts of the eastern states..
*****************************************
Dear Mr. Quinn,
You can find much of the information on MM5 from the MM5 home page
(address below). MM5 modeling system software is in the public domain
(please see the 'Public Notice' on the side frame of the home page),
and any interested person may download it. You may be also interested
in seeing many of the MM5 real-time forecast sites:
http://www.mmm.ucar.edu/mm5/mm5forecast/sites.html
The New Zealand weather service has recently started to run MM5
operationally.
If you have further questions, please contact me. Thanks for your
interest in MM5.
Wei
