Date: Tue, 20 Oct 1998 00:19:44 +1000 (EST) From: Paul GrahamTo: Aussie Weather Subject: aussie-weather: Thunderstorms on Sunday? Reply-Receipt: pgraham1 at extro.ucc.su.oz.au Reply-Read: pgraham1 at mail.usyd.edu.au Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi everyone, I've just been looking at the NOGAPS model (sin!) and it seems to pick up on the trough the Bureau are predicting for QLD extending down into NSW which may bring thunderstorms. What is getting me excited is that, if the model is correct, Friday is just the beginning and it looks even better on Sunday! If you have a look, you'll see a gradual kink developing in the 300Hpa jetstream over central Australia with more of a northerly component into southern QLD and NSW corresponding to a "delta" or "right exit". The so called "delta" region of the jet with upper air divergence is often favoured for strong storms. Surface winds are also forecast to be northerly which would bring in moist, tropical maritime air in the low levels (rather than the dry north-westerlies we've been having lately that have produced only disappointment for storm spotters). I suppose I shouldn't get too excited by a model since Sunday is still a long way off but we haven't a good storm since last summer down here in Sydney (I certainly don't wish violent storms on anybody but, like everyone here, I can't resist a good storm). - Paul. --------------------------- Paul Graham m3052695 at hardy.ocs.mq.edu.au ---------------------------- -------------------------------------------------------------------------------------- X-Sender: kg5 at pop.syd.fl.net.au Date: Tue, 20 Oct 1998 00:16:25 +1000 To: aussie-weather at world.std.com From: Eric Subject: Re: aussie-weather: Sunday's Bushfires... Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Just for the record. I hope this explains some of what can happen. Please read it in the spirit in which it is written, that of Public Education about the realities of bushfires in this country. Before I get to the explanations, here's my qualifications to comment on this. I first joined the Rural Fire Service (or Bush Fire Brigades as it was then) in 1989. In my career as a volunteer firefighter, I have attended in excess of 1,000 fires, including the 1993/94 Bushfires and a dozen other serious "State of Emergency" situations from Sydney to the Queensland border. I now hold the positions of Training Officer and Public Education Officer for a Brigade in the Gosford area, just north of Sydney, the busiest Shire in Australia. I am also Australian correspondant for Wildland Firefighter Magazine, one of the largest magazines of its kind in North America. As far as I am aware, the hazard reduction was ignited on the Wednesday or possibly thursday previous to the weekend. At that time the forecast was for mild weather, with a chance of hot weather on Sunday but with storms and rain expected mid-morning on Sunday. For those who have never taken part in one, unless the area being burned is very small, few fires are -completely- extinguished. For one, it is often almost impossible to gain access to the whole of the area. Another problem that is faced is the unknown number of dead/dying trees that are hollow. These are called "candles" and can continue to smoulder for up to several weeks afterwards. In America, following a fire, tree stumps could still be seen smoking from under 2 meters of snow. Normally the fire is blacked out around its perimiter and the interior is allowed to burn itself out. By perimiter I refer to a rough standard of about 10 meters. Again the reasons are several. One is again access. Another is the safety of firefighters. "Candles" and other burned dead trees create one of the most dangerous hazards that exist on the fireline, and are often referred to as "widow-makers", because they can do just that. Believe me, I've seen a couple of them at -very- close quarters and it is something I prefer to avoid. If a candle is close to the perimiter of a burned area, either it is watched until safe, or the tree is felled. With candles, there are often small (or large) showers of sparks that issue from the top from time to time. Normally these are carried by any prevailing wind. In most circumstances this is only a few meters. However, with days like Sunday, where we experienced wind gusts locally here of over 70km/h these embers can carry quite a distance. I have seen a fire start 20 km from the source of burning embers carried by the winds. Hazard Reductions, when the tree-huggers let us do them, are normally carried out in the cooler part of the year, with autumn and Spring being the most favourable times, as the slightly warmer conditions (especially in the Blue Mountains... brrrr) mean that the H.R. burn will be effective in reducing the amount of fuels available to any future fire. Remember that we are still in the middle of spring, following a very wet winter that caused the majority of H.R. burns to be cancelled. It is very hard to light a fire when it's pourning rain. The forecast was, indeed, changed on Saturday to include the hot, dry winds. Yes, it is possible that "something" could have been done. But what? Pour a thousand men and women into the area to check each and every tree? As I mentioned above, these things can lie dormant for a long time, well insulated inside a dead tree, with little or no indication that they exist. The only possible method of detection -might- be covering every square meter with super-sensitive thermal imaging cameras, although none that I have seen that are sensitive enough to detect a warm pocket inside a tree that might only be the size of a milk bottle can be used to cover a very large area. Even a few Hectares would take forever. The government, it seems to we firefighters, has better things to do than give money to the Rural Fire Service for firefighting tankers, let alone this kind of gear. Although the fact there were two separate fires, some distance from each other (I could see the smoke from here - 100km as the crow flies) seems to point somewhere else, at least for one of the fires. For myself, I spent Sunday attending fires lit by some kind-hearted soul who decided that it would be amusing to give us something to do. 4 Fires, all deliberately lit. Unfortunately there is no easy answer. It might have been caused by something left oveer from a H.R. burn. It is equally possible that something more sinister was at work. It is again equally possible that it was a fluke like two power lines touching in high winds. All 70,000 RFS Firefighters are volunteers, like me. We do what we can, when we can, with what we have. If someone would be so kind as to pay us for the time, I am sure there would be 70,000 firefighters offering to check every tree following every burn. Unfortunately this is only a fantasy that exists inside our minds. If you want to blame anyone, blame the people who are determined to build their nice homes right on the edge of the bush because "there is such a great view". Having nearly been killed a half-dozen times defending such stupidity, I have no sympathy for these people whatsoever. I still fight the fires, because that's what I do, but if a house, surrounded by trees, built at the top of a ridge (fire travels faster uphill) overlooking a thickly grown national park, with their gutters full of leaves, burns to the ground, I shall be saddened of course, but I will never, not now, not ever, accept any blame for it. You want your place to be safe from fire? Build it somewhere sensible, not somewhere that screams out "Burn me! Burn Me!". Until people learn that fire is a natural part of the Austrlaian Bush, and that houses and bush, with its inevitable bushfires do not mix, then this will keep on happening. If all else fails, ask a fireman before you build it. Cheers, Eric J. Berry MIFireE, MRFSA, JP.

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Eric wrote an excellent report. Sorry to snip it:-( [snip] I have to agree with Eric since I've been a witness to many a Blue Mountains fire and I am very sympathetic to way that -this land- was managed by its original inhabitants before they were driven out by invading Europeans. It's just taken us over 200 years to understand some of the forces operating; Southern Oscillation, native flora lifecycles/adaption and the changing climate that one of the world's most ancient peoples came to live in comparative harmony with for nearly 40,000 years. Off soap-box... 1) People must have rocks in their heads to build homes that become fire traps. There is much that can be done to mitigate the risk of getting incinerated but nothing that can be done to stop the worst fire rages other than to try an prevent them in the first place. Managed burn-off is essential. Back-burning in a fire storm means that it's too late IMHO. 2) Some councils have brain-dead policies of tree preservation etc. that result in excessive flamable material building up in reserves adjacent to properties. Common sense dictates that mutual interest are a priority to manage a reasonable buffer zone against properties in volatile situations. These need to be worked on. 3) Water is so precious in this harsh, brown land that is currently green and productive (it won't last). I've just been through an unnecessary battle with council over a water tank that I wanted to build to retain storm water. Trouble was they don't have a policy for water tanks. They only have one for temporary detention tanks and in-ground absorption disposal. What I am highlighting is the backward thinking of these organisations. 4) Now the BoM really needs to get Medium Range Forecasting down to a fine and detailed art. There are probably more suitable people in BoM able to give MRF fire risk reports than me. However, I could copy the mail that I sent last week highlighting the temperature gradient predicted by NCEP MRF and that it would be a "memorable Southerly Buster". I wasn't joking. Now I am a rank amateur, but I know enough about MRF to have said early last week that Sunday would be an extreme risk fire day. After all, the 850mb temperature predicted was 28 degrees for 00Z with an MSL pressure gradient to reckon with combined. That is a hot nor'-wester in anyone's terms and getting that info is almost free! 5) What 4) above highlights is more a general problem of poor communications. Good communication means getting the right info into the right organisations that can use it in a timely fashion. This is where I come at logger-heads with current BoM policy of charging for various services. This is an "anti-communication" policy with the only long-term sufferers being the community at large. This is where something like "aussie-weather" can really assist since it opens up communication channels between interested parties, including those in BoM. It would be good to get some better agreements with BoM and interested parties to improve imformation flow so that incidents like Sunday 18/10/98 are less likely to happen due to proactive rather than reactive management.

We've also had some really good dicussions so far. I've also received some feedback by others on this list on how we should make this list even better! Here are some ideas: * less one liners back and forth * encourage others to not reply to the list, but to individuals if there is no benefit to most on the list - eg. it is not about weather, or it is a specific request from someone about a PC question * more emails with depth offering interesting reading to all I agree with most of the feedback I've been getting and it would probably be good to use some of these ideas, but remember, these are only ideas, we don't have to use them. Here in Perth right now (12:55pm WST), its sunny, not a cloud in the sky, its 21.9C, winds ESE at 10km/h, 1028.4 hPA, and 32% RH. The forecast is for 27C tomorrow, which would be our first day over 25C since late August.

The best storm I ever saw was on Christmas Eve 1978. I was living in Oakleigh in the SE suburbs of Melbourne at the time. The day had been warm and humid top temp 28.8. The day started off mostly overcast with a deck of Ac over the city. this cleared by late morning and the afternoon was mostly sunny and humid. Some large Cu developed during the afternoon, but there did not seem to be any threat of storm at 6pm. when I recorded a temp of 26.7 Humidity 54%. A Humid east to north east air stream had developed over the state and a trough of low pressure was over western and central Victoria. At about 8pm I noticed some large Cu and Cb towards the Nw. Checked the Radio lots of static indicating lots of Lightning activity. went outside again at 8.30pm climbed up on the roof of the house for a better view of the situation starting to get dark. Large cb to the west and North west frequent lightning particularly to the NW. Lightning was still bout 40kms away at this stage so no thunder could be heard. 9.30pm storm was over the city still intenseifying. spectacular display of frequent lightning with many cg flashes. The anual Carols by Candelight was almost washed out. Had to get off the roof for safety reasons and because heavy rain was starting to fall. Storm broke over Oakleigh at 10.00pm and continued unabated for the next 70mins. The sky was electric incessant lightning at least 100 flashes per minute like looking at a strobe light. It dazzled the eyes to look at it for too long. Very heavy rain and flash flooding over most of Melbourne thousands of Households including us blacked out. I recorded 39mm of rain. No Hail or damaging winds. But as I am a lightning fan I rate this as the best storm I personally witnessed. One other good storm I should mention was back in July 1963 a very rare severe winter Thunderstorm. I have not witnessed a winter storm like it since. It started about 9pm( I was only 11 years old at the time). I noticed a lot of lightning to the Sw. Shortly after 9.30pm the storm hit and continued unabated till 6am. Gale force winds frequent lightning Rain and Hail continued all night. 45mm fell in the city I recorded 53mm. Went with my dad down to Richmond in the morning. The houses and lawns in that area were white with Hail, still remember seeing a bloke shovelling hail off the drive ways of a petrol station. Later that afternoon me my brother and my mate Dave rode our bikes over to Caulfield park were we surprised to see many large trees had been uprooted. The VFL(now AFL) cancelled the entire round of League Footy. This is the last time a round of Footy was cancelled. Dane Newman
