Good morning All!
Well, what can I say! It's 2:50am and I'm still
pumping! I was awoken by some distant thunder and
thought it would be one of those "couple of rumbles
then gone".........I was wrong! The lightning
intensified quickly, then I noticed and large dark
swirling "mass" sweeping in from the West. Then I
could see from the street lights that it was a wall of
rain! It hit with gale force winds blowing down some
trees in the park next to us, it was like "all hell
broke loose"! With each ribbon of lightning the
following thunder sounded like canon fire!! There were
several power transformer "flashes"- long green
flashes with an associated bang! There were sensor
lights going off and the rain was coming in
horizontal! I couldn't get a Radar image, when I click
the link nothing happens...maybe someone seen the
Radar image? The wind lasted for around 20-25 mins and
now it is almost calm! There is still some thunder
rumbling now. It will be interesting to see how much
damaged was caused. I should have got the video camera
out, but I guess I was too overwhelmed! Well better go
back to bed and try to get some sleep!
Regards,
Andrew.
PS. At last I have something interesting to report!:-))

Huh??? Plants evolved to deal with more CO2 that what is presently in the
atmosphere, plants would work more efficiently in elevated CO2 levels and
help bring the levels back down. It's ozone layer depletion and the
associated UV that'll kill plants, not temperatures raised by 1 or 2 degrees
and the most important form of plantlife and major oxygen producer is
phytoplankton and that's in the sea. Ozone layer loss is not global warming.
Nor is acid rain, which kills plants.

It's a rotating pulse storm or LP supercell - nothing volcanic about it.
Perhaps the tree got clobbered by a CG from said storm?

Does it - the advertisers are using an emotional argument rather than cold
hard fact - there is no real proof that the planet is warming up - it's only
30 years ago that we were all going to freeze...

Hello Everyone
Not the action here that Andrew had but we did have a thunderstorm pass south
of us at 6am! There is still another line of weather to the west on the radar
and should be here in a hour.

Les
Maybe I didn't explain myself properly in my opening statement. What I meant
to say was more along the lines of the way the media has been brainwashing the
population about this for many years. I was I suppose being a tad facetious
in the way I phrased my statements. The media has, I believe, been guilty for
many years of running an 'imminent disaster' scenario and generating a great
deal of fear in the minds of the average person. I suppose I shoiuld have
opened up my initial paragraph with a statement along the lines of 'this is the
way the media has been trying to portray global warming and is in no way
associated with the truth'.
I was trying to do an overview of the subliminal effect of the photo - not an
overview of what the photo really represented.
My belief is that we've been through many of these global warmings, ozone
depletions and subsequent coolings and we will go through many more. However
I'm quite happy to be proven wrong.

I believe that global warming's a myth - having been through one ice age
prediction. It'll sort itself out - Gaia will take care of that.
Right, well in the meantime if the world gets warmer then perhaps us here at
55N 1-30W might see more of this kind of storm - will have to get into my
solar cell powered car (not mains electric - unless fusion / wind / wave
powered electricity) and chase it....or take the train (us MSC members are
good at that) thats having saved a few whales and recycled a few newspapers
and advertising hoardings on bus stops just before lunch... (:
btw are Sydney buses "eco-friendly" ie do they use hydrogen / rapeseed oil /
alcohol???

Hey, don't those highs look nice situating themselves a little further
north just now?
Almost (I said almost) looks like a winter pattern. I wonder if they'll
stay there for a while? Maybe we might get at least a rain event out of
this next front due in Sunday sometime. Might even get a bit chilly up
our way. Saturday's event left us with 1mm of rain and a bit of wind -
wow.
Hey, looks like I've recruited another weather enthusiast from the
tennis club. He's 18 and has asked me if I would take him on a snow
chase this winter. His name is Adam and he said for me to say hello to
you guys as he doesn't have an internet connection.
And also, welcome John! Good to have you with us. :-)

I have been watching this event slowly unfold. The cold front that was
moving through Friday had become near vertical as well as a slight leaning
to it. It raced out into the Tasman with a dry line event out there and
seems to have stalled or slowed down rapidly. Now Sunday morning, there is
a north west cloud band racing down. Cold air in the Bight is pushing north
east and based on the erratic but prominent instability in the Tasman
caused more by the warm ocean currents and colder upper air temperatures,
it seems that a low will develop over the next 24 - 36 hours off the coast.
It will be interesting to see this system develop.
There are weak storms (even structure shows) from around 7:30am to 8:00am:
one to my northwest and another to the southwest. The northwest cloud band
should drop some decent rain as well but it depends where the low develops
in relation to Sydney as to where most of the rain will fall.

Not sure what you are saying here Les, I will treat it as satire. The buses
in Wollongong are good old diesel, not sure about Sydney. Australia is
almost up there with the USA when it comes to energy consumed per head of
population, and that is a lot more than the UK. On the other hand
Australian's who visit the UK are surprised by the relaxed attitude towards
smoking, in Australia all restaurants have non-smoking areas. Shopping
malls, public transport and work places are all no smoking zones. Hope you
are not smoker Les, you may find your trip chasing downunder different.

Hello all,
What a lovely day it turned out to be in Adelaide, and despite some
tactical blunders and stupid stuffups, my chase had a good ending!
After checking the radar at 1.30, I decided to head north to the Barossa.
But before I left I decided to check out the air display for the Adelaide
500 race. There was plenty of big cumulus around, and as I was watching
the F-18's from my backyard, I was amazed to see a funnel develop from the
ragged base of a dissapating congestus! It was a small rope, but no doubt
about what it was! I rushed inside to get my camera and just got a shot
off before it dissapated.
Not bad I thought, a funnel before I even leave!
So I headed north to Gawler. On my way a large congestus to my right
started to glaciate and develop a lowered base - and low and behold, in
the traffic, a large funnel-like appendage! I was heading away from this
cloud but managed to get a shot off between buildings.
Ahead of me was a large collapsing storm already spreading an anvil
overhead. My plan was to get to the north of new towers developing out to
the east, and I ignored everything else. Beautiful pileus and lenticular
clouds developed over these towers, which had very sheared anvils. I took
more shots. It was looking good!
I finally got to Truro and realised two things, I wasn't going to be able
to catch these towers out to the east, which were much further away that
I'd thought, and worse, horror of horrors, I'd not even bothered to focus
the half dozen shots I'd already taken, including the two funnels!!!! I
was not a happy boy - I really hope these shots can be saved, perhaps in
Photoshop.
Anyway, my options were now limited, and I headed back south through the
Barossa, hoping some new development would catch up with me. I got caught
in hilly terrain around Kersbrook and was beginning to think I'd miss out,
although the sky was still throwing up towers everywhere and there was
plenty of static on the radio. Then I saw a lowering out to the west, this
looked good, and I desperately searched for an escape route to give me a
good view west. I found one, emerging from the top of the ranges at the
Para Wirra conservation park [finding a great new viewing spot]. MY GOD!
Over the Elizabeth area amazing things were hapenning!! Two BIG wall
cloud-like lowerings, only a few km apart, were dropping copious CG's,
precip cascades and showing excellent scud action {inflow/outflow features]
and general cloud motion . Making sure I had the focus right this time
[:)] I fired off most of the rest of the film here. Finally happy, I drove
back through the now outflow dominated storm, got drenched, and fired my
last shot off showing the Torrens River in full spate.
Result? Despite the stuffups, I'm a happy chappy. Hope the film does
justice when it gets back.
Andrew and Kathryn? Hope you had some luck today too! There were that
many good targets around it would have been hard to miss everything!

I don't want to start one of those vicious and never-ending threads about
whether global warming does or doesn't exist - in my experience they rarely
illuminate anybody or anything. I would just point out two things and
encourage discussion:
1] The global insurance industry is certainly taking 'global warming' very
seriously
2] It always suprises me that people get locked into this ideological 'it's
all our fault, were all going to die / it's not our fault, it doesn't even
exist' dichotomy. My take on global warming is that there does seem to be
a warming signal there, certainly the CO2 levels are increasing. On one
level it doesn't matter whether this is a natural cycle or human made - we
are all going to have to deal with the consequences - and one could make
the case that because of our vast population, enourmous installed
infrastructure, and high level of sequestration of the world's biological
resources [agriculture], this civilisation, in spite of its amazing
technological capability, is not very well equiped to deal with large scale
climate change.

Hi all,
The weather documentary that I was interviewed on was on CHannel 9, at
8:30pm last night. Probably the worse thing in my mind, was that they
used my interview, with James' footage (possibly giving the impression
that I took the footage), I wish they credited it to James for James'
sake! However, I also stuidly (or more probably, nervously), made a
mistake saying a gustnado is a tornado over water! (The gustnado I was
thinking of was actually over water, but I twisted the words around), I
meant to say it was a tornado on the gust front! Oh well, hopefully
everyone forgot to watch it, and it won't be too embarrassing :)
They showed some good footage - although in general I disagreed with
some of the opinions of the climatologist they featured (just my
personal opinion).

G'day Anthony + All, I didn't forget the weather doco in Brisbane
last night......All I can say Anthony is VERY WELL DONE
!!! Dont forget that you are your own harshest critic. As far as
your supposed ''faux pas'' are concerned, 99.99999999% of the viewers wouldn't
even have noticed - and that includes the few who have any knowledge of the
subject matter at all. It would have been nerve racking appearing on TV. Also,
as anyone who has a particular field of interest knows, as soon as the
electronic or print media get involved in something there will invariably be
mistakes, misrepresentation of facts plus questionable editing. Anthony, I am
sure that James understands this all too well. I have had a lifelong interest in
meteorology and Anthony, James, Ben Quinn plus the other members of ASWA and the
Brisbane storm chasers have done more to engender a local and practical interest
and understanding of thunderstorm events and features than anyone I can
remember. Good on you all. Anyhow, that is more than enough sunshine blowing
from me...It is midday in Brisbane and there are distant towering Cu to the SW.
Maybe there might just be the odd Cb on the NSW border ranges later..PS Anthony
I am jealous of your Green Flash. Damien.

Hey Lindsay,
I have noticed a slight shift in the high's to the north. I didn't want to
say anything and pull a jinx. It was about this time last year that I got my
first days snowboarding in up at Mt Baw Baw - let's hope for another strong
southerly buster!
I have to hope for this stuff, I'm off to the US in winter, so I won't get
another southern hemisphere season. Though i'll spend a few weeks in NZ on
the way and then be in Colordao for quite some time - can't complain :-)

Do not be too embarrassed, I thought you did a good job with all those
cameras and lights poking in your face. It is not easy to maintain clarity
of thought with all that attention. I have been witness to a 7:30 report TV
interview on an unrelated topic that was conducted in my home when I lived
in Tassie, and I understand the kind of invasion of your space that occurrs
in these situations. You did very well under the circumstances, and I bet
there was hardly a person that even noticed your slip up.
I also understand the way that editing can distort what was said, as out of
a half hour interview they may select a couple of minutes of clippings that
tend to remove things from context. Fortunately, they chose to present you
in a good, if slightly eccentric, light, and in any case, storm chasers
will always be seen as a little eccentric in the larger society. Editorial
bias can be very destructive in the wrong hands.
Once again, well done, and good on yer for having the guts to put yourself
in the media spotlight, which is always a rather risky thing to do.
>They showed some good footage - although in general I disagreed with

>Anthony Cornelius
I think your views on some of the opinions of the climatologist would be
worth an airing here, as it would be appropriate as a follow up to the
program.
Regards,
Carl.

Hi all, well certainly a very active day here. Didn't really take much
notice of the day until about 1pm when I saw a mass of thick black cloud to
my south. I got online and read a couple of emails about there being thunder
as well as Nick telling me on IRC he heard some. I ended up heading out
about 3.30pm to Doncaster Shoppingtown and filmed a few cells on and off for
a while. The storms were high based due to the low DP. One of the lowerings
I saw on a cell over about Malvern seemed to have rotation but it is uncelar
and the video I took of it will have to be studied to confirm this, it
certainly wasn't approaching true wall cloud stage or anything. Caught a few
decent CGs as well but missed a heap more. My interest then turned to a cell
over Melbourne airport about 5pm. Saw some great CGs out of this cell but as
it got closer it seemed to lose its strength. I left Doncaster to head home
(about 5 mins - very handy ) and it started to rain the drops were very
large and I was considering the possibility of hail occuring. As I drove
through the rain there was an incredibly bright flash followed
INSTANTANEOUSLY by a thunder. There was literally no gap and the CG strike
had either hit a power pole right next to my car or it hit the car itself! I
was fine until about 10 secs down the road when it sunk in - hehe. Certainly
an experience and by far the closet CG I have experienced or hope to. I was
shaking slightly by the time I got home but the adrenalin was certainly
there. I just wish I had got it on film or something somehow now. The
strangest part of it was the fact the thunder wasn't very loud which leads
me to believe that I was almost in the channel path of the strike. Anyone
have thoughts on this? Anyone else got stories of close strikes? All in all
a great day and fantastic to have such weather in april which has been
boring for the last 5 years.
Chris

Hi all,
Does anyone have any thoughts on the possibility of SE Aus getting it's
first worthwhile cold change on Friday? The latest GASP run has the 540
thickness line heading north over a bit of the SE on Friday, but I don't
know about the other models until they come out tonight.
The models I have looked at have been a little erratic lately so I guess
we'll have to wait and see but Sydney's extended forecast is for the
change on Friday and a cool weekend...
Andrew.

After a phonecall from Jane at 12:30pm telling me
that there was some serious looking congestus to the SW and W I decided on a
storm chase after checking radar, soundings and forecast charts. LI's of
-1 to -2 and CAPE of 500 or so across Central Victoria had me more than a little
interested, along with the 20knt 850mb winds, 60knt 500mb winds and a 300mb jet
of 105 knts. Also the temperature profile of the atmosphere was
interesting me with thoughts of hail popping into mind with 850 temps of 8C,
500mb temps of -21C and 300mb temps of -46C.
I headed out the Western Ring Road and headed NW on
the Calder Highway to Diggers Rest. I pulled off the road and waited
and watched. Decaying anvils to my N and more
active cells to my S and W kept me interested for about 20 minutes while I
waited for something further W to take off as the cells to the S, while being
the best looking, were heading over the metropolitan area into traffic and
unchaseable country. At about 2:15pm I decided to head for some developing
cells to my W and WSW which were about 50km away. These two cells both had
nice flanking lines and the W cell had a nice overshoot (no photos these as the
features were picked up through small breaks in the low cloud). I headed
WSW towards Melton to intercept these cells which were probably NNW of Geelong
at the time. I stopped briefly in Melton East to take a photo of the cells
to the S and also of a cell to my N, which, although looked nice, was outflow
dominated and not worth chasing. I soon found myself in some familiar
country out on the Exford Road which heads due W towards the Bacchus Marsh
- Geelong Road which was what I was aiming for. Turned S onto that road
and now had a clear view of the line of cells which stretched from Lara NW
to Merridith. I stopped again just out of Balliang East after seeing
lightning from the closest of these cells (which were now combining to form a
line) and an interesting lowering. I got a phonecall from Matt Smith with
a brief radar update letting me know that the line of cells varied
from 2-10mm/h up to 20-40mm/h. I waited here for about 15 minutes
before deciding to core punch this line. I headed S again along the
Bacchus Marsh - Geelong Road but the RFB was soon right overhead and a
new cell was developing closer to the city (now to my E) so I decided
against core punching this weakish line and headed E towards Werribee.
Lightning became more frequent with about 5 or so crackles from the radio per
minute and a few visible CG's just 2 or 3 km away made this drive E very
interesting. I had a heavier precipitation shaft to the S which
was fairly close and CG's where coming out of the RFB between where I
was and the precip shaft. I eventually ran out of road heading E so I
picked one heading slightly N which would take me a little further away
from the RFB and precip area where I hoped I'd be able to take some
photos. This didn't quite eventuate like I'd wanted as the road
heading N was just 500m long. There was a dirt road heading E again so I
turned onto this hoping that it wasn't too wet and slippery as I was
out of mobile phone range. It turns out that this road kept me running
parallel with this system from just N of the You Yangs all the way into
Werribee. While on this road I had a clear view of the
precip area which continued to get heavier just to my S. A new RFB
formed on the outflow of the heaviest precipitation area just up the road ahead
of me as I entered the outskirts of Werribee. I spoke to Jane O'Neill
who was sitting just up the road in Hoppers Crossing taking video of the event
as it unfolded. I told her I was going to continue E to try and get myself
under the RFB before it dropped its load to see if it was going to
hail. I used some creative guesswork to get myself
onto Sayers Road which would take me right under the cell which had
already started to drop a thick rain curtain down from the middle of the
RFB. I sped (literally) along Sayers road but as I was heading into
suburban areas I was held up by slow drivers, traffic lights and a train as
well. I was still about 3km from the precip shaft with only 10km until I
ran out of road (i don't think my car would enjoy driving through Port Phillip
Bay) but I pushed on and entered the rain at Altona and within 10 seconds was
slowed to 40km/h from the torrential rain. The roads were awash and
driving was difficult but I continued heading E towards Williamstown through the
rain which kept getting heavier but I was yet to encounter hail (not that I
could see out the windscreen though - hehehe). I was stopped again by a
train entering Williamstown but as soon as it passed I was heading the last 1km
East before reaching the western edge of the bay. The torrential rain had
flooded the main street of Williamstown with watter lapping up onto the footpath
and stretching across the road in several areas and I encountered some small
hail (to about .8cm). I rang the Bureau of Meteorology and reported the
the flooding in Williamstown and Altona. I headed back into the heart of
Williamstown to take some photos of the flash flooding and found a side road
street totally flooded from one side to the other with about 6-8 inches of water
in the centre and about 4 inches at the sides. I drove through this and
pulled off tot he side of the road (into the flood water - hehe) and took a few
photos of this. I could still hear the thunder from the cell as the precip
curtain was sitting about 2km offshore and there was still plenty of
lightning. As this cell was now unchaseable I headed back out the way I
came to see if there was any more significant flooding between Williamstown and
Altona but it had subsided significantly by the time I drove back. A new
cell had developed to the SW of the other one so I found a spot to pull off the
road in Laverton North and I took some photos of this new cell and the
still-rampaging cell heading across the bay. With over an hour of daylight
left and several cells still firing up to the NW and W I headed out to a cleared
area where I had a view of all the cells and picked the next best
looking one which was to the NW of the city, probably up near where I
started the day at Diggers Rest. I headed back to the ring road and out
the Western Highway. I turned N towards the cell just past Caroline
Springs down Clarkes Road. It turns out that this was also a
"dry weather road only" (dirt road) too. I stopped about 1km down
this road and watched as this cell developed a new RFB and scud formed under
this and was dragged up to the base. This small lowering was not rotating
and I didn't expect it to start given the linear wind shear. The lowering
remained visible for the next 20 minutes as I headed back to the Western Highway
and onto the Western Ring Road. Once again this cell dumped its load just
up the road ahead of me and with the sun setting behind me an awesome rainbow
formed in the orange coloured rain curtain and I took a few photos out the
windscreen. I pushed into the back of the rain curtain and
encountered moderately heavy rain from about Broadmeadows all the way to
Bundoora where I took the Plenty Road exit and headed SE along Plenty road into
what seemed to be the heaviest rain. Within 200m of heading further S I
encountered he heaviest rain of the day with visiblity (while stationary at the
lights) was cut down to about 25m. It had been raining heavily in Bundoora
for a while and this downpour soon flooded the roads again and the intersection
of Plenty Road and Grimshaw Street was like the intersection of two
rivers. I plowed through about 3-4 inches of water here and pulled a
U-turn and then turned towards home down Grimshaw street (all the while still
sitting in torential rain). I encountered more flash flooding at the
intersection of Grimshaw Street and Frye Street and again along the
Greensborough Bypass and more on Elder Street (just down the road from my
house). I got home just as the rain stopped and was informed by my parents
that we'd had hail at our house about 2 minutes before (very small).
I checked the rain guage as the cell moved off to the E and weakened but
thunder was still audible for about 15 minutes. 12mm of rain in
about 18 minutes according to my dad. I'm sure other areas like
Bundoora would've had slightly more but I thought this was fairly good.
All in all a good chase for a late season system.
Thanks to Matt Smith (for the radar updates), Clyve
Herbert (who rang me at the start of the chase), Jane O'Neill (who alerted me to
the developing situation and then kept me informed as to what was happening
where she was) and Claire McDonald (for telling me how good the storms were out
in the E of the state while I was in the W of the state - thanks sis -
hehe).
I hope the other Melbournites enjoyed this
system. Thanks and congrats to Nick Sykes for picking up the potential for
this system yesterday even though the BoM were only going for showers.

Maybe you had your windows up, making it sound heaps quieter than it
actually was, maybe the sound of the rain pounding on your roof deafened
the sound, maybe you were dreaming the whole thing :)
nah, I have heard that the closer the strike from you the less impact it
has, something to do with the shock wave not being able to get to full
strength, I dunno, but the one I encountered whilst watching from my
aluminium door way, didn't seem that loud also, and that was only 10-30 ft
away. Maybe there is an explanation, but I will be buggered if I can
remember it now.
Happy hunting!!!
Andrew

I was shaking slightly by the time I got home but the adrenalin was
certainly there. I just wish I had got it on film or something somehow now.
The strangest part of it was the fact the thunder wasn't very loud which
leads me to believe that I was almost in the channel path of the strike.
Anyone have thoughts on this? Anyone else got stories of close strikes? All
in all a great day and fantastic to have such weather in april which has
been boring for the last 5 years.

Andrew,
I checked the models on Friday and thought the same thing Andrew except I
think it may be delayed until Saturday. Even so, when I last checked the
models, it showed potential for some severe cold air CB's over Vic with
SW'ly surface flow of 25knts and N'ly 500mb flow of 60knts (estimate). I'll
keep checking the models as the week goes by and outlooks will be psted to
MSC page.

Well - I do know something - I can guarantee that while driving, thunder is
very difficult to hear even when very close (i also found out today with
several strikes within 3km of me). I'm not sure if this is due to the road
noise, the movement of the car or something else. Anyone?

Hi Damien, Carl and all,

Interestingly on this note, any factual information that I said was
actually re-said by John Schluter (eg, tornado information, and SE
QLD/border range information), a fair bit of it word for word. Whether
or not this was to portray me as an amatuer, different to experts, or
they decided that it would work better than that, I don't know - but I
won't judge.

My opinions are simply that - opinions, and I'm by no means an expert.
I feel almost guilty for this, given that Roger Stone made some nice
comments about storm chasers :-)
I disagreed with his general opinions of this season, talking about how
wet it has been in SE QLD this summer - when I thought it has been
rather dry! He also said it's a typical La Nina year, where the storm
maximum occurs in Nov-Dec, and then tapers off in Jan-Feb, and instead
it's just humid, and you get showers/rain instead. He also said this
year appeared to be a typical La Nina year. When really, if that were
true - given his description of a La Nina year, then we should have had
a lot of rain in Jan-Mar, but we didn't. Jan and Feb were very much
below average for me, and much of SE QLD. Not to mention, it's been far
from humid in Brisbane lately. That was the most noticable thing
comparing Jan and Feb with March. Jan and Feb were certainly quite dry
(except for the 4 days of summer we had, and DP's got to 26C along the
coast!) That was one thing that made it feel so cool/cold. I thought
March may have been warmer than February. But Blair proved this not to
be the case, however I believe that March overall was more 'humid' than
Jan/Feb. This would be explained by the sub-tropical ridge breaking
down, and becoming less defined, and giving an Easterly fetch across the
Coral, rather than a SE'ly wind.
Also - I believe that it is normal that the number of storms experienced
tapers off as the storm season progresses is associated with each storm
season. Certainly you don't have the air mass 'clashes' that you have
in late Spring/early Summer and the cold air aloft also dissappears.
During Jan-Feb, normally an upper level ridge sits over us. What I
found interesting, was that the formation of the upper level ridge was
meant to be associated with the formation of the Cloncurry Low, and the
heat trough that extends south from it. While the upper level ridge
wasn't as strong, it certainly was present.
Other things to consider during that influenced a different weather
pattern (rather than El Nino/La Nina), would be the unusual placement of
the sub-tropical ridge. It generally sat further north than usual. If
anyone can provide an explanation, or another opinion on this - it'd be
very much appreciated! I often that it had something to do with a
'positive feedback system' with SST's of the water, and the ridge.
Essentially, you'd have the surface ridge driving SE'ly winds up the
coast. This would then create a surface SE'ly current, and push cooler
water from the south up north. Ridges/sinking air favours areas of
cooler air/water - so the ridge would be quite happy to sit there, and
it would 'feed' itself cooler water, and the cooler water would feed
itself a ridge, and the process could go on until a jet/high eventually
moves out of the way. But the effect of the ridge would have displaced
the surface trough further inland, so a feature that was commonly seen
this season were high's amoebaing themselves into the Tasman Sea
underneath and inland surface trough. This then built another ridge on
the eastern coast - and the process continued.
This certainly wouldn't be the only factor that was cause a displacement
of the usual position the sub-tropical ridge lies at. I also believe
that the lack of development from the Cloncurry Low also played a part.
Had the low developed, the surface/heat trough probably would have
become more established, and exerted its dominance over the ridge.
Whether it's a case of something influencing and interfering with the
development of the heat low over Cloncurry that allowed the sub-tropical
ridge to sneak further north, or that it just happened that this year,
the sub-tropical ridge was able to exert its dominance before the low
could form, I'm not too sure. But the poor thunderstorm (at least in SE
QLD), was already evident due to Sept, Oct and Nov all being quite poor
thunderstorm wise. There was indeed an increase in November, but
certainly quite a reduced number. November also recorded its coldest
average max on record - with a plethora of other stations around
Queensland. So something certainly was 'brewing' well before that.
If anyone has any opinions, or information - I'd be very interested to
hear it! As I said, these are just my opinions, and I'm by no means an
expert - so please don't take it as if I'm saying Roger Stone is
incorrect!

Andrew,
While you were in Williamstown etc I was on the other side
of the bay enjoying the spectacle.
Saw a nice CG (around 14:20) hit the water just near
Sandringham yacht club ('home' !!) with simultaneous thunder & heavy rain
& winds that increased from around 10 knots to 25 knots in about 5 minutes.
At about 16:00 or so another cell hit but I didn't get out taking photos
until around 17:00 when I saw the next one heading right for me. I took a
few shots from Picnic Point at Sandringham before moving towards Brighton - I
got some nice shots of the rain curtain at sunset - little bit of mammatus on
the leading edge - and managed to finish off the film & wished I'd had
more!! Not a lot of lightning/thunder in any of them but great
nonetheless.
Cheers

Certainly, it's much harder to hear thunder in cars (with the windows up
of course!) Especially in newer cars that are well shielded from
outside noise, or older/more powerful cars that have louder engines then
other cars.
Another reason, would be the way you're moving compared to the sound
waves (something along the doppler effect of a siren???) If you're
moving towards the sound, or away from the sound - it might have an
effect. But whether or not the speed of sound relative to the speed you
are travelling has a dramatic effect, I'm not sure - just pure
speculation.
I had a similar event on Dec 10, 1999 when a lightning strike hit a pole
close to me while driving. It sounded almost like a gun shot.

Hi macca, great chase report, you did well :). Fair call about the sound of
the thunder whilst driving but this strike was 50m at the very most away, so
I do not think it was that personally. Remember that strike we got on the
2nd March last year that was 100m away but wasn't loud at all - this
experience was very similar to that, just a bit closer and the thunder less
loud. The thunder lasted half a second at most and was more like a poppy gun
going off than the shotgun sound you get when strikes are about 300-500m
away. It was certainly an experience - hehe

Hey all
Yes a very enjoyable day had in Melbourne today.
Woke up about 9 and had a look outside and automatically thought storms,
that beautiful cloud was present castelattus.
Went on chat for a while but was in need of sleep so went back to bed. At
midday I woke (I was planning on 1/2 an hour) and jumped out of bed to see
what had devleped. Was pleasant to see some nice pilus out to the west and a
nice Cb to the east. I started jumping around like i was on beans and
quickly checked radar and sat pic for the latest. Some nice cells were were
evident on radar and some nice cloud tops were evident on the satpic in the
SW of the state. I decided I would head done the SE.
Before I could do anything, my brother came and asked if he could borrow the
car to get an oil filter, the one he had brought was the wrong type. So the
chase was delayed. I spent this time drooling over the sounding which showed
a very cold atmosphere as Macca has already mentioned.
A nice cell came over my place early afternoon (green on radar) and dropped
some very heavy rain. Heard some nice claps of thunder but saw no lightning
Mid afternoon had arrived and my other brother had come over, so we decided
to go out in my brothers car for the chase. At this stage we decided to head
towards the NE out towards doncaster. On the way a beautiful looking cell
had developed to the NW over the city. The way we were heading showed little
promise at this stage so we decided to head towards the city cell (was later
to be found to be St Kilda with red). As we approahed the features of the
cell became evident. A very nice base with some ruffled scud. A well defined
precipitation curtain had developed. We headed just shy of the main rain
curtain to miss the worse of the rain, earlier in the day it was evident
that any rain from these stroms would be very heavy.
That all good and well we still got some very heavy rain. Didn't here any
thunder while chasing this cell.
At this stage it was getting pretty late and my brother had to get home. Got
home and that cell we had chased was putting out some nice rumbles of
thunder, which goes to show it is very hard to hear thunder when in a car.
Overall a very nice day, the main feature of todays storms would have to be
the size of the rain drops, i have never seen them so big in cold air storm
before.

I have had similar experiences. I recall on Dec 14 1998 a lightning strike
hit just ahead of my car, and it was more of a explosion than a deep boom,
like i was used to. I can think of two reasons (none of which have any
scientific knowledge behind them).
#1- The insulation, like anthony said, is very good on cars, so you only
get the more louder 'harsher' sounds (...middle range to high range..??)
and the deeper bassier sounds are muffled and lost.
#2 -The deeper, lower sound waves which make up the 'booms' travel at a
different level away from the strike, so at ground zero, where the strike
occurs, the deeper sounds 'miss' you because they need the surrounding
atmosphere, space (whatever...) in which to travel/ and form. So at groud
zero you get a higher pitched gunshot sound and further away, when the sound
has bounced around a bit you get a lower pitched sound.
Do i need to draw a diagram?? =)
Again this has no scientific knowledge behind it, just 'speculation'

He he.
I even taped it (maybe I'll send it to Jimmy). I really liked the shot of
Anthony divining (or was that worshipping?) a storm from the edge of the
road up Mt. Coot-tha. They even used their helicopter for that! But
congratulations for having the balls to do it!!
I agree with you totally Anthony. But I will go further and say I thought
that what Roger Stone said was, by and large, a load of dingoes kidneys. I
found little cohesion in his argument. While I also think we are trending
back towards '70's style climate, I certainly can't see the argument that
this summer was a classic indication of this. Then again, perhaps if you
lived at Springbook or Maleny you might arrive at a different opinion.
Regards,
John.

My 0.2c worth (actually make that 0.1c).
I would presume that maximum intensity sound waves propagate at right angles
to the lightning channel, which would correspond to the direction of air
displacment. On that basis, if you are directly underneath a point of
lightning contact, such as the top of a power pole, and further, the flash
is fairly vertical, then you are close to 0 degrees of the channel path. I
can see an argument for the sound being less loud than were you say 50
meters away and hence close to 90 degrees of the path (using a line drawn
from you to the nearest section of the lightning channel).
I don't know about you, but I ALWAYS wind the window down during a
thunderstorm (so what's a bit of rain...), to make sure I get the most out
of the bangs. (Oh you poor sick person).
John.

Another reason, would be the way you're moving compared to the sound
waves (something along the doppler effect of a siren???) If you're
moving towards the sound, or away from the sound - it might have an
effect. But whether or not the speed of sound relative to the speed you
are travelling has a dramatic effect, I'm not sure - just pure
speculation.
