Between 1:30am and 3am, he received 39mm. However, in between 1:30am and 2am, there was 25mm, most falling in 10 minutes in what could be described as violent thundering rain due to the large drops. ---------------------------------------------------------------------------- --------------- Jimmy Deguara from Schofields, Sydney e-mail: jimmyd at ozemail.com.au homepage with Michael Bath http://www.australiansevereweather.simplenet.com/ -------------------------------------------------------------------------------------- 002 From: Paul_Mossman at agd.nsw.gov.au X-Lotus-Fromdomain: NSW_AG To: aussie-weather at world.std.com Date: Thu, 31 Dec 1998 09:26:04 +1000 Subject: aussie-weather: East Coast Lows. Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi Andrew. While I may not be able to give it the best meteorological explanantion as Paul G or Laurier would, East Coast Lows typically form at the change of seasons on the NE to E Coast of NSW due to the greater temperature gradients from change of seasons. These see the pools of very cold air making it somewhat further North then allows in Summer coliding with the warm air from the Land. This assists with rapid convection and hence the rapid development of these beasts! (I apologise to all Meteo's out there for such a simplistic view... :-) Paul G makes a very interesting and valid point with reagrds to a possible ctaegory for these South Ocean Lows or even east Coast Lows. They are cyclones lets face it - just Cold centred rather then warm centred. The BOM could put a warning that say a Cat 2 Southern Low will form and have winds gusting to....and the areas that may experience weather form that Low. Good Point Paul G. Paul. -------------------------------------------------------------------------------------- 003 From: Paul_Mossman at agd.nsw.gov.au X-Lotus-Fromdomain: NSW_AG To: aussie-weather at world.std.com Date: Thu, 31 Dec 1998 09:42:20 +1000 Subject: aussie-weather: Medai & BOM Responsibility re: Severe Weather Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Well it seems like the BOM may be in for a hard time soon. The NSW State Coroner is holding an inquest into the deaths of the people associated with the Sydney to Hobart race. The State Coroner can make any reccommendations he likes or even recommend that charges be laid for criminal negligence. So looks like the "weather" and forecasting responsibilities of the BOM and the distribution of that information will come under the spotlight. Will be very interesting to see the result.

Everyone on this list knows that storm cells/Low preasure systems and so on have a mind of there own. They can increase and decrease in size in a few hours. That had forcast that one it just came through stronger then they thought. You do ask and interesting question though, what would/will/could he change? Hmmmmm, I'll have to think about that. Lets just be careful what we right as we may be held in contemp if we are not careful. ****************************************** Grant Boyden -------------------------------------------------------------------------------------- 011 From: Paul_Mossman at agd.nsw.gov.au X-Lotus-Fromdomain: NSW_AG To: aussie-weather at world.std.com Date: Thu, 31 Dec 1998 10:27:18 +1000 Subject: aussie-weather: Contempt.

Date: Wed, 30 Dec 1998 17:18:40 PST Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi Paul, Grant, David and others, I have enjoyed reading the discussion on warning distribution. Here's what happens at the BOM end in NSW. When we issue a severe thunderstorm advice or warning, it is sent by fax directly to all radio and TV stations that we know of in the area under threat (it is also available immediately on Internet and pollfax servers). We then rely on media cooperation in broadcasting these to the public. In order to help the media understand the working of our warning service, we issue a Media Information Package each year in cooperation with the NSW SES. Well over a hundred copies were handed out direct by us this year and many others no doubt copied and passed on to their local media by the SES. We also hosted with SES a launch of the 1998/99 "Severe Storm Season" on 8 Sept that received good media coverage, particularly outside of the Sydney area. You may recall that this is the time the election was called! To assist in their broadcast, our advices and warnings all have a start and finish time and are updated when necessary (warnings every 30-60 mins). Some radio and TV stations are particularly good with reading out our messages, or displaying them as crawlers, and the communities they cover undoubtably benefit from this. Following the Yamba-Byron Bay storm we asked people to ring us with information on the storm. Of the 2 dozen or so people who took the time to do that, about 20% had heard the advice.

Do you think this would be feasible? This would allow a continuous update of the storm situation rather than having to wait for a local radio station which may only broadcast the warning once in the advice period. My idea would be to have a scattering of MW or HF AM radio stations for this purpose - I believe the US NOAA weather radio is only available to those with the right type of receiver (I think it's on VHF). Such a network should be as widely accessible as possible, so ideally you would want to be able to receive it on a normal AM/FM car radio. What do you think of these ideas? - Paul G. ---------------------------- Paul Graham paul at marconi.mpce.mq.edu.au ---------------------------- On Wed, 30 Dec 1998, Andrew Treloar wrote: > Hi Paul, Grant, David and others, > > I have enjoyed reading the discussion on warning distribution.

From what I know, they tend to form along the coast where the temperature gradient in the sea is greatest since there is a tongue of warm water, some distance out to sea, flowing down the east coast of Australia. I think that frictional drag of surface air moving over land may slow the wind deflecting it seaward, therefore aiding in offshore convergence. They also tend to intensify during the night (destabilisation due to radiative cooling of the atmopshere?). They can be warm or cold cored depending on their origin. For example, they may be the result of a tropical cyclone moving south, an inland low moving off the coast, a NE flow along the eastern seaboard from a high in the Tasman, or a cold front moving over the warm sea. In all these cases, there is some sort of upper air disturbance that favours development. - Paul G. ---------------------------- Paul Graham paul at marconi.mpce.mq.edu.au ---------------------------- On Thu, 31 Dec 1998 Paul_Mossman at agd.nsw.gov.au wrote: > > > Hi Andrew.

One the ABA ( Australian Broadcasting Ass.) do not have enoght frquencies to do this. If they did/do they would go up for auction and would cost an arm or a leg, or both. They do not give anything away anymore. If you could set up that type of a network, there would be no set frq. which would mean each town u would go to would have to be on a frq between 87.5 - 91.0 FM and they would only be 1-10 watts max. This would not really help some one. The idea is a good one, just in practice it would not work I fee. I really do no the answer and It was good to read Andrews view point. I would guess from that, that his fax would go to AAP who would type the data up and send it out to 2UE, 2GB, 2DAY, MMM and 2KY and all the others. That seems to me to be why we have a delay in getting the data. I don't want to fly the flag of 2KY but, we treat all storm reports as high priority as we broadcast to nearly evry toiwn in the state. If we can help, with up to date data there would be no problem having some type of code of conduct put into operation at the station so as the data is give out straight away. Sorry to harp on this but, if the data was available we could put a computer in the studio so as the annoucer could zoom in on the storm and give reports. So could all the other stations and it wouldn't cost much, if the data was free. Interesting though and Andrew thanks for writting. It's nice to hear the view of the otherside in this discussion. ****************************************** Grant Boyden -------------------------------------------------------------------------------------- 035 Date: Thu, 31 Dec 1998 12:57:09 +1000 From: Anthony Cornelius [cyclone at stealth.com.au] X-Mailer: Mozilla 4.5 [en] (Win98; I) X-Accept-Language: en To: aussie-weather at world.std.com Subject: Re: aussie-weather: ASWA venue??

We are not going to pay for any venue. We are a non-profit organisation and will have to hold the meeting at clubs until we get ourselves established. There is a possibility of getting a venue arranged but I am waiting on verification. Otherwise, we have to apply in writing to the boards of clubs and so on asking for free use of the function rooms once a month. Another possibility are universities but I am trying to stay away from that one. We will see. If anyone has some contacts who could arrange such a venue on once a month basis, it would be very much appreciated. On another note, I would suggest others from other areas of the country volunteer at least for this year to help establish their branches. It's OK to say we form a group, but we need people to get involved. This is the most important part. Please don't feel like you have to get in front and run the show, you just have to keep a tab on who attended, what is discussed and so on. So have a go. Anyone who feels they have something to offer in terms of a need to set up the interstate branches, please cocntact Matt. Remember, anyone is welcome to do it. If nobody does it, you will have no branch in your area. The more the merrier. Our first meeting to get things going was a success and fun too. People got to meet each other, we watched videos exchanged photographs and stories. This is what you are missing out on by not having have these type of meetings.

I'm at Hurstville and can almost see the airport but can not get Sydney Atis. I can just get Bankstowns Atis and I'm sure you'll agree that they are one of the best ways to track a cell that is coming over Sydney. If you used AM that would work but to cover the state you would still need a number of them. FM is the only TX's that are being given out at the moment. If you used SW the only problem would be no one would be listening. Don't get me wrong please. I agree with everything, everone is saying, I just do not think they would work well enough that way. ****************************************** Grant Boyden -------------------------------------------------------------------------------------- 042 Date: Thu, 31 Dec 1998 14:40:30 +1100 (EST) From: Paul Graham [pgraham1 at mail.usyd.edu.au] To: aussie-weather at world.std.com Subject: Re: aussie-weather: Media Communication of Severe Thunderstorms.

The downside of AM is interference from lightning and other sources. If a VHF network were setup, you would need a greater number of relay stations but, using FM, you would have reduced interference. Also, I think it is important to have such a network as accessible as possible so it would be desirable to have the broadcasts within either the AM/MW or FM/VHF broadcast bands. Perhaps a network of low cost and low powered VHF/FM transmitters within the 88->108Mhz range would be the way to go?

It was primarily developed for coastal waters forecasts (by the same people who brought the yachting community "WeatherAlert") but we have worked with them to extend it to severe ts advices and warnings. You only get the ones appropriate to the area you are travelling in. Another option we are exploring is using email for warnings. This eliminates fax queues.

So I thought I'd do a quick report... I was awake quite early at my dad's farm (situated in Hiddenvale, 5km S of Grandchester, which is about 20km SW of Marburg - in the Lockyer Valley area) At 6am, it was 8/8 overcast, looking very much like rain, the BoM's forecast was for "cloudy and rain periods." I was hoping it the cloud might thin out a little, but I wasn't too confident. Although the DP was 22C, and was 23C at 6am, which wasn't too bad for in the country. At 8am, there were some breaks in the cloud, it was thinning out fairly quickly, and I also saw some Altocumulus Castellatus! I immediately changed my personal forecast to "storm" when I saw this, as by 8:15-8:30am the sky was screaming "storm!" At 9:15am, while doing checking the fences on the tractor, I noticed a congestus line to my S. At 9:45am it was 31C, DP of 23C and a line of congestus/TCU had formed to the S, and was spreading to the SW. But this remained like this until 12:05pm. The temperature was now 37.1C, DP still sitting on 23C. Some Cb Calvus had now formed to the SW, within the next 30mins updraughts looked rather strong, and the first signs of precipitation were obverved. By 1pm, thunder could be heard. But this cell actucally moved north. Another cell had formed to my SSW by 2:00pm. By 2:20pm, it was looking very nasty with some very deep and dark rain shafts, and a visible ragged shelf. I was surprised that no warnings had been issued at this stage. As there were too many trees for my liking, I then quickly took the tractor back up to the boundary fence on top of the ridge (I wasn't feeling too safe with a storm nearby, and being in a tractor with a 2m tall metal muffler and being the highest object within kilometres!) I took a few picture and observed the storm, she had a hint of rotation in it. At the rear of the storm, I observed a funnel shaped, cloud lowering with rotating scud beneath it. It didn't appear to be a true funnel, but rather just a cloud lowering that looked like a funnel. However within about 5 minutes, this began to dissapear and went back up into the cloud. A visible CG to my S convinced me to drive back as it would be too dangerous. At 3pm another cell to the SW had formed and was heading our way. At the same time, the cell the S (previously SSW) had it's rain shaft divide into two within about 1min, then a rather obvious cloud lowering came from underneath it (it was difficult to tell if it had rotation in it or not) However again within a few minutes, the cloud lowering disappeared and the rain shaft took its place. At 3:15pm, I heard a dull roar from the coming wind. At this time, all of the insects had stopped chirping, and many of the birds began to fly away (often associated with the erie 'calm before the storm.' We began getting S'ly winds of about 30-40km/h, this then proceeded to 40-50km/h. Soon it began to spit, and then light rain came down. Winds were now gusting to 50-60km/h, but for the next 10minutes, never went below 40km/h! The rain steadily became heavier, at the heaviest stage, the rain was pelting to hard on the ground, the gravel on the driveway was actually getting knocked about, and some of the gravel was 'jumping' from the impact of the rain! I was expecting some hail, there was a light green tinge, but fortunately for my dad's car and mum's beloved cattle - no hail fell. The rain and winds continued to pelt down, gusts were now 60-70km/h, possibly 75km/h. But no indications of 80km/h winds in our immediate area. Some small twigs, leaves and branches were also falling off a couple of the trees. The wind was actually whipping the water off puddles on the ground, to make a mist on the ground! It looked awesome the way the 'mist' was just shooting through across the ground! Very soon the winds changed to a N'ly direction, gusting at around 30-40km/h, and within another 5mins, completely died off. By 3:45pm it was a complete drizzle. I went to check the rain guage, juding by the run off, the puddles and the way the rain came down, I actually estimated about 30-40mm of rain (of which most would have fell in 15-20mins) However only 16.9mm of rain was recorded - but throughout the storm - except for the last bit with the light rain, the rain was completely horizontal! So 16.9mm wouldn't be accurate. There was no visible damage on the farm that I could see. However when coming home this morning, a few kilometres east of the Grandchester area, there were numerous large branches down, and some fallen trees. One barn/animal shelter had lost a sheet of corrugated iron off its roof. From what I saw, the damage was indicative of 90km/h (possibly even 100km/h gusts) winds! ******* This brings me on to something else, how many other storms like this occur without any warnings? I didn't report the storm, because apart from the rainfall, according to the BoM it wasn't severe. But as the storm moved on a little, it was. Perhaps the BoM should have storm spotters report "near severe thunderstorms" so they can issue a precautionary advice for people downwind of the storm. Because if what I saw yesterday, was any indication of what normally goes bye without notice, then they're going to be in big shock one day!

Blaming the BOM for bad weather is not unlike blaming doctors that lose their patients. I've stayed out of this one for a while but geez! A 25 year event (essentially quite hard to predict - not just the onset but the development) is hardly the fault of the Bureau. Yes, the dissemination of information may well have been a tad slow, but to err on the side of caution is hardly the exclusive prerogative of weather bureaus. Having sailed a bit myself (in younger years) I know that most yachties keep up with, and are generally well aware of, the upcoming weather. Yes, they could have (and in hindsight, probably should have) postponed the race by a day (as I believe, the Melbourne to Hobart did). However, there were many very seasoned sailors in the S-H race and all would have been aware of the possibilities (particularly veteran racers) and prepared accordingly. The more vexing question of land storms remains. This is an area where warnings should be much more up-to-date, however, during holiday periods, the general public is just as likely to say that the BOM is scare-mongering. I believe that the Bureau is probably in a no-win situation. If they don't issue, say, a severe storm warning and one occurs, they cop the flak from the general public - if they do issue one and nothing happens, they cop the flak from traders and other people who rely on holiday income for their livelihood. I have no answers, but I think blaming the BOM is a bit easy. Yours, Kevin from Wycheproof. -------------------------------------------------------------------------------------- 051 From: "Matthew Piper" [mjpiper at ozemail.com.au] To: [aussie-weather at world.std.com] Subject: aussie-weather: Blue Mountains Weather and Happy New Year Date: Thu, 31 Dec 1998 15:52:33 +1100 X-Msmail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.5 X-Mimeole: Produced By Microsoft MimeOLE V4.72.3110.3 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi Everyone, The weather here is overcast and drizzly with a temperature of about 22.

I think it may have been November 1994 but I am not exactly sure. I remember watching the storm front approach. As it was nearly overhead, the pressure dropped so suddenly that my ears popped - like ascending in an aircraft! Then a gale force wind came whistling through for about 30 seconds but there was no significant damage. Apparently a couple of buildings in Chatswood had a few of their windows shatter - this was attributed to the sudden pressure drop. - Paul. ---------------------------- Paul Graham paul at marconi.mpce.mq.edu.au ---------------------------- On Thu, 31 Dec 1998, Anthony Cornelius wrote: > Just one extra thing - towards the end of the storm, the pressure fell > so quickly, all of our ears were popping! > > Anthony -------------------------------------------------------------------------------------- 054 X-Msmail-Priority: Normal To: aussie-weather at world.std.com, aussie-weather at world.std.com From: "Nandina Morris" [nandina at alphalink.com.au] Subject: Re: aussie-weather: ASWA Motto Date: Thu, 31 Dec 98 17:37:29 PST Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com X-MIME-Autoconverted: from quoted-printable to 8bit by penman.es.mq.edu.au id SAA06923 Nandina from Mulgrave Matthew, Hello and Happy New Year, I like your motto suggestion very much.

I was going thru my email today (31/12), & I agree 100% with Paul about the media & BoM not giving warnings about the storm that came thru Yamba, Evan's Head & points North. SURELY there was SOMEONE in the BoM looking at the radar when the storm changed direction & headed north. Even if we had 5mins warning it would have been better than what we got(! at #$&%$ nothing!!!!!!!!) I think the BoM & the media should pull their collactive fingers OUT of their backsides & get together to try & give warnings when severe storms are around & which way they are heading. That's my 2bob's worth, if anyone thinks I'm wrong, LET ME KNOW!!!!! On another note, thanx to Michael for taking me out on the chase yesterday.....it was good to get some pointers on what to look for in storms (but I still think he scared them off!!!!!!!!!!). I'm linked up with ICQ so if anyone wants to talk online when I'm on, my ICQ no. is 25440353.
