Non the less, I thought it was worth putting up. > Anyone care to comment? You are correct, the resolution is inadequate to tell much. It does appear to be an intense hook-shaped echo within what would be called in the states, an "HP" (high precipitation) supercell. What I see in this image makes me think more of the northern hemisphere rather than the southern. However, considerable research over the years has shown that the low-level scan is inadequate in the vast majority of cases to diagnose storm structure, intensity, or severity. It is the three dimensional structure of the reflectivity echo that can reveal, much of the time, storm severity. In brief, if a storm is severe in an environment of moderate to strong shear, in three dimensions, one looks for the existence of an echo overhang, a "Weak Echo Region" (WER) or "Bounded" WER (BWER), and the echo top displaced toward the WER/BWER flank of the echo. Of course, in low-levels one looks for a concavity bounded by strong reflectivity gradients and open toward the direction of storm relative low-level inflow into the updraft. On the rear flank of this concavity sometimes can be seen the "hook-shaped" echo. Often the high reflectivity core of the echo is displaced toward the updraft flank (often the concavity) of the echo. In the southern hemisphere, these features are most often found on the north or northwest side of the echo but it will vary depending on the updraft flank of the storm. The radar needs to be operated in what is called a volume scan mode enabling diagnosis of the three dimensional storm structure. This should be done at least once every 5 to 8 minutes. This is necessarily a *brief* discussion, of course. Les ************************ Leslie R.

Some nice Accas around today...mixed in with some Ac, Cc and Cs...very hazy too. But the DP is extremely low - only 13C! 24.8C here at 8:50am. Given the current conditions, I don't think much will happen. But, a seabreeze should override the NW'er this afternoon, and that should put the DP back up into the high teens. It'll be then it'll all happen I believe. But the seabreeze will remain a critical factor for today, the earlier we get that NE/NNE'er, and the further it goes inland, the better today will be for t'storms.

I've never seen this blueishness as clearly as this. Maybe it was the angle of the sun from behind, but there didn't appear to be any gaps showing the sky behind. Can anyone elucidate on this effect? Could the blue be caused only by the sky behind or is there another cause, similar to the green hail lighting effect? Cheers, Peter Adderley. +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ 020 Date: Tue, 16 Nov 1999 17:56:44 +1100 From: Michael Scollay [michael.scollay at telstra.com.au] Organization: Telstra Strategy & Research X-Mailer: Mozilla 4.5 [en] (X11; I; SunOS 5.5.1 sun4m) X-Accept-Language: en To: aussie-weather at world.std.com Subject: Re: aus-wx: ASWA Radar archives - some confusion?

There is a big difference between the archive of radar images and their access through ASWA > BoM. The archive scripts that run on my workstation every 10 mins, on the hour and daily, 24hrs per day, 7 days per week perform the following functions; 1) Automatically download each radar, satpic or msl image for selected URL's that include BoM radar, NPMOC gmsc/gmsd and gmsfull plus BoM MSL charts. 2) Automatically delete duplicate and undersize images and compress proper images into manageable files. 3) Provide a long-term archive to 4GB DAT tape. 4) Uploads from the archive are currently manual. Cropping of satpic images can be performed in a batch mode. The archive allows the arbitrary selection of individual images and the animation of selected images. It was/is intended that the ASWA archive would provide a reliable source of images. In practice, there are often periods when the internet, BoM, NPMOC or even my workstation and internal network has trouble leading the the loss of images. In general, the archive is 97% complete, but lately, it has taken considerable effort to complete requests due to numerous problems. The purpose of my previous mail was to seek a review of what radar sites the archive would include in the light of archive request feedback and ASWA needs, particularly with the approaching storm season. Each additional radar site adds between 1.8 and 2.4MB/day to the archive which already increases by 52MB/day. In conclusion, I must stress that the operation of the ASWA archive comes with Telstra's blessing while it is under development and trial. Within a certain period of time, alternatives will need to be sought. Previous mail has outlined the scope of this.

A brief history. 1) Got lots of requests ready to ftp but I couldn't upload them. 2) I put these requests on an unmirrored file system. Guess what?, the disk crashed (that's Murphy). Not only did this crash bring my workstation down, it also corrupted my "Networker" backup tape indexes. I only keep about a month's worth of "on-line" images. Older images are archived to tape monthly and backed-up by Networker each night. 3) I set about to recover lost images from my archive backup (a basic "tar"archive) since this was to prove easier than to attempt a complete "Networker" backup tape index rebuild with no guaranteed success. 4) In the meantime, our firewall support people have been waiting on a patch from Sun for the ftp proxy. This has arrived! but has not yet been installed because of Y2K testing taking a priority:-( The upshot is that an ftp of requested images will be possible on Thursday after I am advised of a successful patch installation in the ftp proxy server. Stay-tuned.

Hi all, pretty cold down south today with a top temp in Melbourne of only 15.8c. There was some isolated hail (small) in some suburbs this morning and several centimetres of snow at Mt Baw Baw. Currently 6.00pm it is 13c in Kilsyth Dew Pt 4c. Well the forecast charts are looking good for later this week with a low presure trough expected to develop over eastern SA on Friday and move in western Victoria on Saturday. BOM is forecasting isolated showers and thunderstorms in northern Victoria on Friday, these are forecast to become more widespread Saturday to affect all districts. At this stage it looks like the trough will still be in the vicinity on Sunday with more showers and storms across Victoria. Looks like the Big Chase may start off down south!! What does everyone else think? Dane (Kilsyth) Melbourne. ASWA Victoria.

To the NW of Brisbane, marble sized hail was recorded to 15cm in depth! (6 inches for our US counterparts). A very nice little lightning display over the northern suburbs...I had some one phone and inform me of some spectacular CG's near the city, with some nice pink edges. As the storm moved closer to my direct north, I quickly ducked out to an advantage point with my camera. On the way there, I saw some fantastic lightning, some real "curvy" lightning crawlers and CG's, also with pink edages! However, as always, as soon as I got my camera/tripod out, the lightning display had tamed somewhat. It was difficult taking photos, the wind was quite strong (15-20kn N'ly) and it was rocking the camera slightly. I think I might have got one or two shots though, but we'll see. Southern suburbs seemed to have gotten the short end of the stick again as usual in NW-SE moving storms. Just some rain and local thunder here, but fairly intense cells to both our north and south. Most of the storms are clearing right now, but there's some cells forming up the central coast, snother nice cell near Gympie in the Burnett region and the BoM has issued a STW for it. Some more showers near Dalby, but I think we'd be a bit too lucky for them to turn into the last line of storms and hit here. But we'll see what happens. Should be some more damage reports from other cells to the south, as they were quite intense. Will report them if they do come through. -- Anthony Cornelius Queensland Coordinator of the Australian Severe Weather Association (ASWA) (07) 3390 4812 14 Kinsella St Belmont, Brisbane QLD, 4153 Please report severe thunderstorms on our Queensland severe thunderstorm reporting line on (07) 3390 4218 or by going to our homepage at http://www.severeweather.asn.au +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ 028 X-Originating-IP: [203.35.254.2] From: "David Croan" [wxbustchase at hotmail.com] To: aussie-weather at world.std.com Subject: Re: aus-wx: Singleton Supercell??

Hi Paul and all, I have to say that the development of strong / severe thunderstorm activity in the Sydney-Hunter area this afternoon and evening has taken me completely by surprise (much like the 14/4 HP supercell did) - I expected everything to be Northern Rivers. Certainly that Singleton cell looks very impressive. I spent about 45 minutes watching the Sydney storm for which the warning was issued. I was watching from Frenchs Forest and it appeared to be somewhere in the vicinity of Terrey Hills. One thing of note was the very strong directional wind shear - low level cloud was racing in from the east while mid levels were moving rapidly from the south and higher still there was a stornger westerly component - very chaotic sky indeed. I imagine the limiting factor for supercells around here today would be buoyancy rather than wind shear - so based on the very cold upper temps which you mentioned to me I suspect conditions may have been favourable for supercells. great stuff!

It seemed that something here was fueling the updrafts as they weren't forming anywhere else, with just flat boring cu everywhere. Mid afternoon a huge updraft went up, and from where i was took up my entire vision. The updraft wasn't boiling or didn't look like storm type stuff, but was solid and formed very very quickly. At about 3pm a few of these cells, which were just blue dots on the radar started to show up as yellow. After some observation i saw that one north me, over the richmond area looked quite established, and was beggining to drop some close CG's. I got in the car to have a casual look. It this point it was very hard to see where the actual storm was. Beyond a lot of middle and lower level cu, there was forming a big thunderstorm. I drove away from the storm for about 15 minutes,to get a better view while thinking that the whole thing had dissapated. But a phone call from Matt Smith saying that he could see great updrafts encouraged me. So, back into the fray i went. After 25 minutes I spotted dynamic lowering, that was attached to long line of very heavy looking scud. The storm seemed to have stalled, or was moving very slowly and was hard to judge where it was going. So after some naviagtion i finally came across the storm. I seemed to be under this lowering, and it was pretty dark all around, but nothing was happening. So I kept on when my actions suddenly became so clear. I couldn't see much because i was pretty well under the centre of the storm. Heading northwards i came accross heavy drops, then as i turned into a corner, i was confronted with a wall of hail. It belted into my windscreen very hard, the size of the hail hard to determine at this point as it was shattering when it impacted with the car and also the amount of debry in front of me was incredible. For about 2 minutes, crawiling along the road, my car withstoood a barrage of dense hail and rain. ( i was on Boundry Rd, Oakville at this point-west of windsor). I pulled over as the hail became even heavier,. and wound down my window where i was cracked on the forehead by a 20c piece of hail. ( i have the bruise to prove it). Eventually, after at least 2 minutes of this it eased, and i proceeded northward. I turned right, then right again so i was heading south, virtually adjacent to the road i headed north on, execept about 1km east (ie closer to the storm.) Moving south, the rain just seemed heavy , until it began to once hail, again. This the hail was so dense at this part, and the rain so heavy that the road i drove upon was a blend of a icy-mush, and seemed to engulf the road surface so much that traction was a big problem. I U-turned and headed back down Boundry rd, from whence i came. There a saw about 5 cars with cracked windscreens. Occasional hail was falling but it had all moved east, evident in the black curtain that was slowly sweeping away from me. The road and surrounds was covered in a thick spread of hail. At one point there were drifts higher than a foot, although these seemed to be at the lower parts of the road. All the drains were blocked, and making my return to home a few of the roads were, in some spots, almost a foot under water. I stopped at a grocerer on the way back and he was repairing some canvas tarps which had been punctured by the hail. The thing that struck me about this storm was how so much came from a day where showers were expected, how long the storm seemed to regenerate for, and how dense the hail was. It was some of the thickest, densest hail i have seen.

I was sitting at a set of traffic lights and had half a dozen close pulsing Cg's ( < 200m) in about 30 seconds! One of these Cg's also knocked out the traffic lights briefly.. and dozens of other Cg's within a few Km's throughout the storm.. the storm (?) then produced quite a nice lightning show when they moved out into the bay.. all in all a very nice afternoon.. Just called energex, and they had over 70 suburbs efected by power losses at one stage.. mainly rural areas, and south of the Brisbane CBD.. Radar and lightning tracker images (both of which are actually quite nice - especially radar) will be available within 24 hours in the recent events section of BSCH..

I had suspected that storms could develop today over the ranges and possibly just touch on the Sydney area. But I was so busy today, I only recall the growing congestus and did not see the storms develop. This is unusual for me so I must have been busy. After school, we were just aboutt to leave say around 3:00 to 3:30pm when I noticed a sudden burst of heavy drops. Then it was followed by ting sound. Jimmy knows the sound of hail and so I indicated this to the others. I had brought my camera along just in case but left the video camera behind so went home and got it (broke the record for the fastest time to get out of car and back in with video camera!!!). I headed to Riverstone (4:!5pm) for a brief observation point and footage and photos and then headed straight for Windsor (4:30pm). Once cell with hail had moved E and I then aimed at the rear cell developing rapidly SW of Richmond from the outflow of the previous cell. And boy did it take off!!! By the time I headed into the Windsor township, I had Matt ring me once and then again with the warning. There were large drops and then near the RAAF, hail began to fall with very heavy rain. I then headed after some footage towards the local Railway Station (Clarendon) and video taped some hail falling occasional larger ones but most pea sized to 1.5cm. When the bursts of hail was over I headed for Windsor again. Any opportunity I could get, I video taped the structure and the base of the storm and then as I headed for Oakville, the hail was getting larger with stripped leaves over the roads and in some cases, minor haildrifts making the road slippery but ok. I video taped this and head after the cell. The damn trees and the confusing road network kept me guessing. Luckily the storm did not moved that fast, otherwise it would have been all over. Around Kenthurst, I stopped to get some great footage of the base and hailshaft region. I noticed that the wind was turbulent with some lowerings but this is typical of hailstorms. This storm did have good rotational wind shear with inflow from the SE and also a W wind on the NW side. The downdraught also came from the storms on the NW side and was quite strong. I chased this storm further through the Galston Gorge and on to Asquith area or outskirts of Hornsby.The locals had come out to observe the hail covering the road. Hail was around 1.5cm to 2cm and covered the grass and roofs almost completely. I then headed for the Berowra area near the old toll gates. From here I got some more photos and footage including the possible supercell near Singleton, hard to say which one. On the whole a great afternoon of practice chasing, partially unexpected particularly the hail (LI from the previous model seemed to indicate best), and also great to see a hail drift for the first time and experience a storm developing overhead rather than sidetracking your area and teasing you. It was also great it was not that fast moving which is a problem travelling the roads of Sydney. Well done all the other guys who chased or videod (Dan, Max, James and David) and thanks to Matthew Smith for the excellent updates. I know he would have like to be there but that is chasing. When you are busy, things happen.

Coincidently, 10 years ago around Christas, as the day of the Redcliffe tornado. This monster supercell formed at the border ranges, and spawned a tornado down there. It then moved NNE and spawned another tornado at Redcliffe (about 130-150km/80-90miles) away. At this time, the storm had tops of 57,000ft. I had originally thought this cell had just travelled out to sea, but apparently not so! I had thought this tornado 10 years ago at Cedar Pocket (that took off the roofs of two houses) could have been part of the same storm system, ie another supercell developed near Gympie. But Jeff said the Redcliffe cell actucally moved northwards along the coast! As the cell moved north from Redcliffe, it went over Newport, where the tornado track stopped, with "definate straight line wind damage" observed. A yacht had it's anneometer jammed on it's 100kn/185km/h maximum from these straight line winds (not a tornado as I and others had originally thought). It then moved over Bribie Island, where tornadic winds/pattern damage was again observed. A young girl was killed at Bribie Island from this tornado :-( It then moved north through the Sunshine Coast and left quite a mess. Over the next 1-2hrs, it continued to grow to a height, reaching 77,000ft/23.4km. A photo of this cell was actually put into the Spotters' handbook. I scanned this image, and uplodated it. You can find it at: http://www.bsch.simplenet.com/anthony/Dec89scell.jpg This was taken at Tewantin, about 100-120km/70miles north of Redcliffe. It apparently tracked just along the coast. Details a touch sketchy...as this cell knocked the Brisbane radar out. I'm guessing Mt Kanign radar was being used to follow its progress. Finally, it went through the Gympie area, with the new report of yet another tornado being reported at Cedar Pocket. In summary, this cell: - Reached 77,000ft/23.4km - Travelled about 350km/220miles - Spawned 4 different tornadoes, the closest two were about 30-40 apart. It's also quite possible others were spawned too, but not reported/did no damage. Interesting how some cells just follow the coast up, and others don't. The Brisbane Jan 18, '85 supercell didn't do this, even though it had max tops at 60,000ft/18km and caused ~400M damage (inflated figures), recorded a 101kn/187km/h gust (straight line winds, no tornado reported at all from this cell!) accompanied with cricket ball hail. The observers at the AP were apparently hiding under their desks from this even - not surprising given 7cm/3 inch hail + 101kn winds blowing :) But this cell actually just collapsed as soon as it hit the ocean. Other interesting cells will be the 'famous' Sydney April 14 supercell, that followed the coast northwards. A believe 2 recent very large supercells in NE NSW have also followed this pattern (ie, moved Northwards just along the coast). It all seems too much of a coincidence for me. Does anyone care to comment on why they believe this happens? Perhaps it has something to do with the way a storm can tap into hot, humid air, and warm moist air behind a cooler air boundary? I remember seeing a post on a US wx list one time about an AU supercell over the coast, and they described this as strange - which lead me to the assumption that the US doesn't receive many 'coastline supercells' - is this true? -- Anthony Cornelius Queensland Coordinator of the Australian Severe Weather Association (ASWA) (07) 3390 4812 14 Kinsella St Belmont, Brisbane QLD, 4153 Please report severe thunderstorms on our Queensland severe thunderstorm reporting line on (07) 3390 4218 or by going to our homepage at http://www.severeweather.asn.au +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ 040 X-Sender: jra at upnaway.com X-Mailer: QUALCOMM Windows Eudora Light Version 3.0.6 (32) Date: Tue, 16 Nov 1999 08:18:20 +0800 To: aussie-weather at world.std.com From: Ira Fehlberg [jra at upnaway.com] Subject: aus-wx: Singleton Supercell, radar tips Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Ive found that the radar never shows up supercells good, in fact i dont think ive ever seen one here that did have the hook. On a few chases ive done, ive got back and looked at the radar and the SC was actually the crappiest looking one! Unless they are huge and even then the rain may not be in the same shape as the hook. Some good signs for picking supercells off radar are, speed, SC's do motor along, most pulse cells are slowish. Not always the case but a general rule. Life span for obvious reasons. Pulse cells rarely maintain good strenghth for longer than about 50-100k's and they usually turn into a wide band of showers after a while. Ive seen SC'c travel 800-1000k's. One other point is that SC's here in WA seem to track a little straighter than most cells. The typical cell here tracks NW-SE or thereabouts. SC's seem to be more straight E, they seem to turn early in their life and straighten out. They move like this sometimes to obtain better inflow, or the inflow pulls them that way. When other storms on the same day are still NW-SE. The eastern states is obviously different and someone else may be able to comment on direction a little better. A possible example of this is the local radar right now! That cell that starts out just E of Newcastle at 11:00UTC then it turns and tracks N, i dunno i just noticed it then, it does seem to straighten out a bit. http://www.upnaway.com/~jra/IDR043lp.gif BTW That Singleton cell sure looks good!!
