To: aussie- weather [aussie-weather at world.std.com] Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi everyone. I was interested to find a page which has some severe storm reports (of sorts) from the Netherlands + links to what seem to be a few other chaser pages (my Dutch is of the double variety so I can't read much of it). One particular storm, a classic supercell at the time given the hook echo which is apparent on radar, occurred on June 6 1998 and produced hail to 10 cm and a tornado (no pics!): http://haven.www.cistron.nl/06june98.htm Also, on one of the linked sites, I found a few photos of a shelf cloud ahead of what may have been a squall line - looks pretty impressive too: http://www.geocities.com/CapeCanaveral/Hangar/5549/severe.html (one of the Dutch sites did link to the ASW URL and to those of a few other aussie storm related sites) When I was in Germany a few years back (August 96) there were several consecutive days of storms, one storm in particular, which moved through the Berlin area, had a really spectacular gustfront with intense lightning and a dense precipitation curtain - looked severe. Since then I have always wondered how western Europe fared in terms of severe thunderstorm events compared with eastern Australia. Based on the model data I have been looking at, it would seem that our spring summer atmosphere is more often conducive to deep convection but I guess wherever the right conditions come together you will get some some significant storms, as was the case there on the 6/6 (there is a modified sounding for the day in question on one of the sites - I think CAPE was around 2500 J/kg). Just on the Sydney AMOS weatherwatch meeting, it was a great presentation by Rob Webb. As an aside I asked him what areas he considered severe storm 'hot spots' (i was thinking in terms of chase destination and expecting him to say around the Tamworth-Tenterfield-Moree-Coonabarabran box); he mentioned Sydney, Hunter Valley and the Grafton area. Despite some recent dry years, it is quite incredible when you consider the frequency of severe storms which move over the relatively small Sydney basin. Certainly, and all in the last 9 years, Sydney has had the three most damaging thunderstorms on record in Australia with only the 1985 Brisbane storm approaching the same destructive magnitude - pretty amazing stuff. _________________________________________________________ Do You Yahoo!?

Caused a lot of excitement at the time - the second supercell in Europe in 5 years! This baby was set off by seabreeze front convergance. > > Since then I have always wondered how western Europe fared in terms of > severe thunderstorm events compared with eastern Australia. Western Europe can and does get severe weather - with hot moist air from the Medditeranean, elevated areas of dry air from the Russian Steppes, moist unstable Arctic air and warm moist air from the central Atlantic all this and a jet stream aloft most of the year round makes the whole of Western Europe severe weather prone. There is no definate "chase season" as such - tornadoes can be spawned at any time but are usually weak. We also have the problem of lack of data - weather is an official secret both in the UK and the NATO countries - no friendly NWS or BoM here! We also have a poor and congested road network and extortionate fuel prices these make the european stormchasers lot not a happy one! The UK can get 33 tornadoes a year, on average, and parts of Europe can also get severe weather - there was a supercell in Switzerland in 1993. The attitude of the media here leaves a lot to be desired "freak" is the usual word used. Which it isn't. At the beginning of this year there was a T7 (F3) tornado in France - AHEAD of a cold front. Had supercell written all over it. Last week (22/5) there was an MCS in the Midlands (Birmingham) - rotation, pea sized hail, brilliant gustfronts, continuous CGs but no tornadoes. Today (28/5) at Wallsend there was a brilliant gust front as a severe multicell passed over - torrential rain and CG at about 4 a minute! > Based on > the model data I have been looking at, it would seem that our spring > summer atmosphere is more often conducive to deep convection but I > guess wherever the right conditions come together you will get some > some significant storms, as was the case there on the 6/6 (there is a > modified sounding for the day in question on one of the sites - I think > CAPE was around 2500 J/kg). Sounds about right - higher CAPEs have been reported.

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com On checking the web site below and looking at the 6 day surface chart prediction there is a forecast of a 'cutting-off' low forming near Adelaide and moving northeast. I am a bit skeptical that this will happen but if it does, I think we'll get a major cold and wet outbreak over SE Australia (another ECL from a different direction!) There's also another tropical depression in the Coral Sea. Anyone have any thoughts?

Also: http://www.met.hu (Hungary) had a severe weather section under construction if you thought Dutch was bad, try Hungarian!! NB Hungary gets one tornado every ten years or so but they get plenty of the wet stuff dumped. There are photographs on this website from one of their metmen stormchasing in the USA (obviously never heard of NSW) Chuck Doswell on his website has an analysis of two severe weather events in Spain - again LI's and CAPE values approach those found in NSW. +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 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------------------------------ -------------------------------------------------------------------------------------- 006 From: "Grant Boyden" [boyden at zeta.org.au] To: "Aussie Weather" [aussie-weather at world.std.com] Subject: aus-wx: Media Has Helped Date: Sat, 29 May 1999 20:01:19 +1000 X-Mailer: Microsoft Internet Mail 4.70.1161 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com As a member of the media, I would just like to point out how much the media has helped people over the years with regard to weather.

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hey Keith.. I wouldn't believe it myself no, any model forecast more than 72 hours out is to be treated with caution, and when you get into the 120 and 144 hour forecasts you can pretty much say it's "dreamcasting" more than "forecasting".. I have also found in my experience with the models over the past 7-8 months that MRF is notorious for being 'wild' outside 120 hours, and even over 72 hours at times.. It would be a good idea to follow the situation this model is forecasting, and watch how much the forecast will change leading up to it..
