Although this is not the trough line, it is the eastern edge of trough, where the air has unstable enough to generate Cu growth without the aid of daytime heating. You really can't miss anywhere along this line from about noon onwards, the only dampener is that there is some high cloud, but it is slow moving and should not reach to far NE just yet. My hope is that a line of storms will grow from the before mentioned Cu and castellanus, if so the Sydney chasers and Wollongong chaser should be in position A, that is on the northern flank of the storms. I will hang at home for the next hour, 02 4297 1693, if anybody wants to chase, after that I will closely watch radar and probably head towards Picton.

Hi Michael, Paul Graham and I are planning on chasing this afteroon. We will probably head to Rooty Hill or Horsely Hill and, the way things have developed over the past few days, end up around the picton-Canden area. Paul no longer has internet but I will be online until about 12:00 when we will head out. (our contact no. on the road is 0412 655 134).

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com A few words about satellites and the web; 1) GMS satellites never move out of range until they fall out of the sky or are turned off. 2) Satellite reception is sometimes affected by both local and extraterrestrial radio interference. We can't do much about that except remove local sources and that means setting up your own receiver and knowing how to do that. 3) The WWW is notorious for poor fetching of data from prime sources. Most of the stuff we enjoy is automagically assembled, never checked and never quaranteed. 4) Last two weeks in particular seemed to full of problems in the internet particularly with name serving and mail. I'm not surprised that files are turning up with no data, particularly if they are dependant on getting a raw image ftp'd from some directory somewhere which turns up with default blanks. Basically, the internet is living up to its name of "best effort only". So if we want more reliable sources of satellite imagery, then we need to find sources closer to home ('net-wise) in the hope that this might isolate us from instabilities related to access to international sites. ,-_|\ Michael Scollay mailto:michael.scollay at telstra.com.au / \ Telstra Technology 7/255 Elizabeth St. Sydney NSW 2000 \_,^._* Strategy & Research snail: Locked Bag 6764 GPO Sydney 1100 v Sydney NSW Australia +61 2 9298 5891P +61 2 9298 5820F -------------------------------------------------------------------------------------- 009 Date: Mon, 14 Dec 1998 11:44:43 +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: aussie-weather: Blue Mountains storms -- 13/12/98 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Laurier Williams wrote: > > Perfect circles are pretty rare in nature, but have a look at the > radar image for 05.20utc yesterday in the loop at > http://www.lisp.com.au/~laurier/aussie-weather/9812130520IDR033lp.gif. > Any theories?

I would be interested to see this sequence overlayed with topography, lower and middle layer wind velocities, directions and relative humidity. From my position in Lindfield watching the development of these storms to my W, their demise coincided with a fundamental wind change from NW to variable SW/SE at the surface. What was happening higher up was difficult to work out. It was as if the southerly blew these storms out. It certainly coincided with their stalling from what I could see. My interest in topography stems from an interesting correllation of the circle on its southern flank to the Blue Mountains. Perhaps topography had something to do with maintaining the required lifted index. ,-_|\ Michael Scollay mailto:michael.scollay at telstra.com.au / \ Telstra Technology 7/255 Elizabeth St. Sydney NSW 2000 \_,^._* Strategy & Research snail: Locked Bag 6764 GPO Sydney 1100 v Sydney NSW Australia +61 2 9298 5891P +61 2 9298 5820F -------------------------------------------------------------------------------------- 010 From: "Greg Spencer" [hawk at aisnet.net.au] To: "Aussie Weather Mailing List" [aussie-weather at world.std.com] Subject: aussie-weather: Possible Storms in Perth Date: Fri, 4 Dec 1998 08:34:39 +0800 X-Msmail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.0810.800 X-Mimeole: Produced By Microsoft MimeOLE V5.00.0810.800 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi All It's currently 8:55 am here and I have been watching a large band of tall Cu to the south of me.

The sudden intensification at 04.40utc and subsequent development certainly correlates with the main Katoomba -- Springwood ridge, and the development on the eastern side (to the west of Penrith/Richmond) a little later could be coincident with the Lapstone Ridge. Jimmy and Michael B reported that the most severe wx (hail, rain curtain) seemed to be in the vicinity of or to the south or southeast of Bell, again on a ridgetop. From my position at Blackheath, the heaviest clouds and all thunder were coming from between N and E. Note the intensification of echoes NNW of Lithgow around 05.20utc -- possibly coinciding with the high country W of Portland, and the general westward movement of the western side of the circle. Is it possible that the downdraft from the storm east of Lithgow in the 04.00 panel combined with topography to produce the effect?

It always seems to go out just when things are starting to get interesting. I wonder if it is the result of backups or maintainance being done on the server at a quiet time in the US? I would support Paul Graham's attempts to examine the feasibility of developing a groundstation which could load timely and higher resolution images onto the Web locally. I would also be prepared to chip in a contribution if the costs could be divided up and end up not being too expensive. Perhaps the new Society could become involved and have a number of levels of subscription fees which could provide access to addtional services that are bought in bulk or are expensive as a one-off (such as setting up a satellite groundstation) and pass the savings onto members. It would be good to provide as extensive a range of products to members as possible as part of the basic subscription. I am mindful, however, that some people will want the society to access more and potentially expensive data that not all who want to join the society would be interested in (or could afford to pay for) the additional services. It may, of course, be better for such arrangements to remain as private between individuals and not necessarily involve the society.

It passed through Sydney CBD, in the last 10 minutes (15:55 to 16:05) and is still venting its anger on the city's buildings. I stood on the balcony of our building, observed the gust front blowing away people's umbrellas etc. and several CG strikes on city buildings. Some CC directly above Hyde park just about popped my ear drums. No hail or observable rotation from my perspective looking mainly N to S across Hyde Park. Very dark with plenty of prangs bringing emergency vehicles out. A few fire alarms also just to keep our fire-fighters busy. Basically normal city storm chaos.

I checked the rain guage and it registered 25mm in a period of about half an hour. The hail was only sparse and did not cover the ground at all. Before the storm arrived there was strong gusts of wind from the south and then a short time later during heavy rain there were strong gusts from the west. While the hail was falling the wind seemed to pick up for a short time from the north west.

The wind from the south was quite gusty, covering the lawn in bark and leaves. It began to rain lightly, and the wind shifted to the south west. I went out the front and stood on the porch, and it started to pour. Then the wind blew the door shut, and i was locked outside :) It started to hail, and continued to hail sporadically for the next 20 minutes, but never bigger than pea size, and mostly a lot smaller, and mixed in with a lot of rain. The best part of the storm was the lightning, heaps of CG, a few strikes visible each minute in the limited portion of the sky i could see from the porch. The thunder was continuosly cracking, banging and rumbling for the whole time, it seemed strange when it stopped. quite a lot of the thunder arrived at the same time as the forks of lightning. Lots of the cg's would flash on and off 4-5 times for about a second. The gutters were overflowing onto the porch, and the 5mm wide, 2cm long wound on the bottom of my big toe that I was trying to air and dry out after being bandaged for a week while i was in tasmania got totally wet. My mum arrived home from work about 4:15, by then the heavy rain had been stopped for 5-10 minutes. I went out the back and looked at the rain gauge. There had been 33mm in about 20-25 minutes. The maximum temp for today was 34.8, and the minimum was 22.0, but the storm brought the air temp down to 19.

Paul and I arrived at Rooty Hill at about 12:30. CAPE was very high (I don't have J/kg) although the jet stream was fairly weak. Unfortunately visibility was poor - a lot of mid level gunge and moisture haze. From about 13:30, through all of this, we observed an anvil to our immediate northwest (over the blue mountains) and also one going up to our southwest. There was so much going which made any decision on where to chase difficult. Luckily Michael B called and gave us a run down on the activity as observed on RADAR (thanks Michael). Michael mentioned a few cells over the mountains (probably those we observed) and a north-south line of strong echos (some red!) extending from ~ 200 km south up to around Katoomba which he expected to move over in about 1 1/2 hours. At about 14:00 when we next spoke Michael mentioned that a severe thunderstorm advice was out for several forecast districts (including the Sydney metro) and mentioned a bow in the line around the Camden - Bowral area. Decision time: do we attempt to get down to Camden and toward the bow echo which would probably be the best position for tornadoes to develop or do we stay put. The fast movement of the squall line forced us to stay put. We hoped that Michael T would be chasing that area so he would at least be able to tell us what we missed. We also had hoped to meet Michael and Jimmy on Rooty Hill at 15:00. However, with the ever darkening sky to our west (still poor contrast due to mid level cloud deck), we were getting edgy and decided to head off towards the storm. The line was simply awesome on its approach (I hope the photos do it some justice): spectacular lowerings, extreme turbulence, intense CGs and a green precipitation curtain. We experienced heavy rain and some small hail although we deliberately avoided the 'mean' area which was a few km's to our south. I will write up a more detailed chase summary and send it and the pics to Michael for Storm news online soon.

Mysteriously around 11am the castellanus cleared to the NE, one small cell developed just south then moved over the ocean, for a short while the only cloud visible was high cirrus ( my view to the SW is limited ). A radar check near midday revealed nothing in the immediate area.. 1pm and another radar check, a line of thunderstorms was now clearly visible out near Goulburn, I did an animated loop and thought I had at least 1 hour if I wanted to get the storms at Bowral. I decided on the infamous Macquarie Pass route, I was not in hurry as I thought I had my calculations on the storm speed under control. I even pulled over at a small creek near the pass to photo a wildflower that took my fancy. On the road again and the 13km trip up the pass became a 30 min crawl stuck behind two loaded semi trailers, the bottom of the pass was wavering between 28C -29C, at the top it was a cool 21.5C and low fog had set in, this is not as unusual as it sounds. Again not in a hurry I pulled over and took a video of the fog, I thought I heard a rumble, but dismissed it as yet another truck. Five minutes up the road and into the town of Robertson and it was rather gloomy, the fog should have lifted by now I thought ( the fog usually only drapes the escarpment edge with non-rain event NE winds ), looking up the main street of Robertson and I saw lightning reflecting through the low cloud. Less than 2 mins later on the west side of Robertson and a squall line was clearly visible. Within seconds the rain started to fall. It became very heavy and the wind rose, I pulled over about 5km west of Robertson. Numerous CG's were occurring in the area, small hail to pea size started to fall. After the a few minutes the rain eased and I proceeded westward again, another band of rain from the rear flank hit me near Wingecarribee Dam, again I pulled over to film the heavy rain and strong winds. After this last band cleared I again headed west, no more than 1 km up the road I came upon a large branch almost across the road, there were other small branches down as well. I pulled over again at the first available spot and appraised the situation. Do I head back east and try for the rear flank photos, or do I head west into some developing smaller cells. I decided to turn back east, to cut a long story short the storm was simply moving too quick and by the time I was back in Robertson it was already crossing the escarpment, I therefore headed to Bowral. Lowerings from the first storm were briefly visible to the NE in no mans land, I only wish there was a road through all that Sydney Water catchment zone. On the north side of Wingecarribee Dam is an excellent view to the west and south, a cell was developing nicely south of Bowral. I drove a few kilometres further and took some photos, the rain was moving towards me very quickly, just in the time it took me to change a film the rain from this storm had covered at least 2-3 kilometres and I was yet again in heavy rain. I pressed a little west to get a out of it, as it stopped I turned back east and took some photos, boy ! these storms were high tailing it. I got some shots of some nice, but non-severe cloud tags and scud that was very wild looking. That storm gone and back to Bowral and yet another small cell, this one also had a few CG's, like the previous cell it too quickly moved NE. The view westwards was now looking poor ( for storm chasing ), it was clearing rapidly. It was now about 4.30pm, so I decided to take the M5 freeway home via Picton. I ran into another storm on the Picton Road and scored more CG's. Storm number 4 for the day, but only storm number one had the hail and strong winds. At home at last and my wife said that there had been lightning and rain, but no hail or winds. A good day and some nice video, the photos will be only so-so, too much cloud, too little contrast. On reviewing the video I was disappointed that the CG's did not come out, although I have finally mastered the art of the focus lock, I have ignored the exposure lock, so when I was taking video whilst driving the exposure would set for the dark road, the sky would immediately white out. Next video I will get in all together at last !!
