Crosby at 1:50am. Midnight temp was 15.5C under a clear sky which is mild, all things considering - no doubt wind chill factor is up, although so is humidity at around 60% - high for Westerley - guess it's because this is air circulating quite tightly around the ECL thus the air stream probably came onshore around Coffs. A true winter westerley would come across much of Southern Australia and be very dry, <15%. Can't see it getting sub 10C here tonight.

It's been constantly gusty here, 15-20kn - max gust of around 30kn though - nothing absolutely huge. Applethorpe has been 8C from 1-2pm, and 9C before that - it hasn't got up to 10C yet today!!! Toowoomba is 9C, I have 18.3C here right now, after a max of 20.1C - it'll be a cold night, high single figures...brrrr, but when the SW'ers lighten off (and last time I looked the models are going for lighter SW'ers) then it'll be even colder :-( Anthony from Brisbane +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 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------------------------------ -------------------------------------------------------------------------------------- 002 Date: Wed, 14 Jul 1999 16:43:49 -0700 From: Lindsay [writer at lisp.com.au] X-Mailer: Mozilla 3.0 (Win16; I) To: aussie-weather at world.std.com Subject: Re: aus-wx: NE Southern Tablelands Wx Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Nothing better except for sound of snow falling on the roof.

There's too much of a difference compared to 166km/h. One thing that is often forgotten/not understood is that wind power is the square of the initial multiplication strength (bad wording, sorry...) But basically, 200km/h is not twice as strong as 100km/h - but 4 times as strong (200/100 = 2, then square '2' and = 4) This would also mean that this gust would be 4 times stronger then any other gust recorded on land. At 166km/h - you'd expect lots of trees down, rooves blown off, and a flood of damage reports. The ECL only went down to 999hPa (as far as I know) and while ECL's have tight pressure gradients with highs, and do not need to go down to great depths in pressure to have strong winds, for an ECL I would be thinking 975hPa would be needed to give a gust of 90kn. 166km/h is at the top of the Cat 2 scale for TC's. The only thing that I could think of, would be a 'coldie' - such a tornado would not be unexpected in a very highly sheared environment - 'coldies' and TC-related tornadoes are very similar, they both require highly sheared environments. Tornadoes on tropical cyclones are very common, although generally are not mesocyclonically induced (although there have been exceptions). Shear at 850mb was 30-35kn, with some of it up to 35-40kn from the AVN analysis yesterday. Undoubtedly, the weather can do almost anything unexpected or unexplained, however unfortunately I still cannot believe 90kn/166kmh Just my two bob, Anthony Cornelius Michael Thompson wrote: > > Although 90 knots is possible in an East Coast low, you would also expect > that sort of reading on an exposed cape or headland, my experience is that > ECL winds die off very quickly the further you move from the coast.

If the gust was reported from a localised storm that moved overland, it is possible but Paul needs to supply more information. Like Anthony said, we need evidence of damage and so on from that area and whether there was a storm associated with the gust. For instance, during the 1986 major flood ECL, a report came in from Pendle Hill which is located well inland from the coast. The report was described as a localised very intense wind by the media. I found out later that it was reported as a tornado by the BoM. But damage was obviously reported with this event.

Noted at 9:00am that the Westerley was still blowing but had moderated considerably - but go up a couple of thousand feet and there was cloud drifting in from the SE. Now 11:00am and is dead calm with more cloud & drizzle patches approaching from S/SE. Either the ECL has taken off for NZ , or simply collapsed. I thought the Satpics yesterday arvo were good - you could see the really tight circulation just off NE NSW. Seems to me that it was/is part of a very complex low, with this ECL forming to the West of the main trough line. From the radar obs, which showed two distinct rain bands, I wouldn't be surprised if there was second weak low down off the coast near Newcastle which initially was centered on the 'rotating thunderstorm' observed two days ago. Comments anyone... Regards John. >snip Hi Anthony, Still howling at Mt. Crosby at 1:50am.

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hey all, Let me tell you about today. I was out at Gawler Plain, about 50km north of Adelaide, doing a native vegetation survey with a friend. It was a mild cloudy day with a northerly airstream and the occasional light shower out of thickening mid level cloud. Around 1.30pm I noticed some vertical development and a lowered base quite a distance away probably over northern St Vincent's gulf. I took a snap but didn't think it would amount to anything. We went to lunch and were inside for about an hour. On going outside and heading back to Adelaide I couldn't believe what came into view! This thing had drifted much closer, had a dark lowered base, and what looked like inflow bands. I got my camera out. No sooner had I done this than a funnel dropped out of this lowered base!! I couldn't believe it! I could see little bits of disconnected scud swinging around this thing! I took 2 snaps through the car window (please let them turn out) and just as we were waiting for the thing to drop to the ground, it retracted into the cloudbase!! The funnel had lasted perhaps 2 minutes. We tracked the cloud all the way back to Adelaide. It had some interesting base structure, but it developed a weak precipitation cascade offshore and never looked like dropping a funnel again. What more can I say? There was no severe weather around Adelaide today, and the radar offered only weak yellow shows over the gulf. Needless to say I'll post the pics when they are developed! Did anyone else spot this sucker? Andrew????

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi Phil, While reading this, it immediately reminded me of a similar event I witnessed last year in September. http://www.flatrate.net.au/~cyclone/1998sept.jpg <-- This is the photo. It occurred under a relatively lower Ns base (as you can see on the picture). I know many people do not believe this was a funnel/tornado - however, afer long hard thought, I believe it was. It lasted for 5 minutes, before it went out of view (dad refused to stop the car &*(&^&*(^(!$ him) but, it was moving horizontally across the ground, and as you said, you could see the little 'bits of cloud' moving around - at the time I didn't notice rotation, nor was I looking for rotation. My eyes were just glued to this thing, and I had totally unexpected it! At times, it changed shape slightly (on a slight slant) but other then that, the shape remained fairly uniform. This to my knowledge, occurred as a cold pool of air. Anyway - I'll let everyone judge for themselves Anthony from Brisbane Phil Bagust wrote: > > Hey all, > > Let me tell you about today.
