Not used to this soaking. The sun came out today but not very strong and any heating producing weak gathering convective Cu and hense blocking out the sun which was a bit of a niusance. We have had the September average rainfall so far already and only half way through the month. No thunder/storms yet apart from storms along the Southern Alps and that boring tornado at Hokitika the other Thursday. Mind you the media never used the M word so that's something. One year and 20 days since the last time thunder was heard in Christchurch. I thought I would let you know.

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi Jimmy, Yep - showers are convective clouds too, so certainly microbursts from showers are no strangers in some situations - I think the main thing is that most convective showers either: a) form on a SE'ly stream hence too much low level mixing b) form when storms are going to occur that day, so any damage reported might be classified as t'storm related, not shower related. In regards to what do you call a microburst from a shower if it falls under the wind strength definition - it'd still be called a microburst :) Microbursts and macrobursts are downbursts - so if you call something a downburst, then it either has to be a microburst or a macroburst. Microbursts are less then 4km wide, so it'd be called a microburst if it's less then 4km wide. As you said, the dynamics are analogous - it's simply a matter of scaling.

Hopefully all the bushfires now occurring in the district will reduce the amount of fuel so that when we get a gusty NW'er day in late Spring/Summer with temps around 40C it won't be so bad. --------------------------------------- ABC Weather News Report: Brisbane is having its driest year on record. The Weather Bureau says there has been no substantial rain in much of south-east Queensland since last year. Senior meteorologist in the climate section, Barry Gordon, says Brisbane has had just 344 millimetres so far this year, and that is less than 50 per cent of the long-term average. "Certainly in Brisbane I had a look at some figures the other day and we've had below average rainfall, I think every month this year," he said. "We're really having to go back to last year sometime and I must admit I don't know the exact month to find out when we've really had a good wet month. "The strange part is that most of Queensland, apart from the south-east quarter have had an average to above average rainfall. "It's just been the south-east and the Darling Downs that seemed to have missed most of the rain throughout the whole year." End of Report. --------------------------------------- After saying all of this, during this afternoon we experienced our first gusty SE winds in a long long time, bringing humidities into the 60's. Cape Moreton reported a few gale force wind gusts as a matter of fact. In Brisbane/Logan during the morning we had light-mod SW winds until the change to SE in the mid afternoon. My max temp was 28.4C and Amberley's was 29 after a minimum temp of 4C. Tonight we have up to 8/8 altocumulus keeping the temp around 15C. A Happy Olympics to all!

(snip) It is not Brisbane's driest year on record. It is the driest year so far on record at Brisbane Airport, whose record goes back as far as 1949. Even allowing for the site change, though, 1902 (which had 179.4 mm at the Regional Office for the year to August, 212.5 to the end of September and ended up with 411.7 for the full year) leaves this year for dead. That said, combining the RO and airport records leaves this year as number 2, which is still quite impressive. 1977 is the last year to get close, with 401.5 mm in the city and 371.9 at the airport for the year to August. (Most of the big Queensland drought years of recent memory, like 1991 and 1982, had one very wet month in Brisbane which bumped the totals up a fair bit). The last wetter-than-normal month was December 1999 (marginally), and October 1999 was very wet.

Great stuff! Was just talking to someone about this area the other day. Especially here at Rutherglen. Some heavy rain passed over here several times in the past week or so and it's as if it just "stopped" at the edge of town. Maybe this new one will pick it up. Even the Very heavy rain around the time of the Milawa incident was only showing Dark blue if I remember around 6-6.30pm. It was a fair sized storm as I was watching it and it was definitely dumping more than was showing up. Maybe we have a "dead spot" here. I know, I know. There's a joke there. Grin.
