This was recorded in Cherrapunji, India. Australia's greatest one year rainfall was 11,251 in 1979, recorded in Belleden Ker, QLD. Although this does seem a lot, how about 38mm in one minute, recorded at Barot, Gaundeloupe in 1970!? That's a rate of 2280mm an hour! Of though it didn't rain for that long of course.

The new moon seems to have a bearing influence on the cycle of weather. If it rains ont he first few days on or just after the new moon, then it is probable going to be a wet month or unsettled. This could be viewed as "well it was raining anyway, so it rained on new moon and kept on going" but it's not that simple. I had tried to test out another hypothesis... Farmers believe that if the moon facing with it's belly down, then this signifies more rain ...etc over the next lunar month but if it is facing sideways.... standing, then it is going to be a relatively dry more settled month. Every time you try to prove it incorrect, it seems to hold. So I tried to make printouts based on the predicted precession and nutation positions of the moon (N-S movemenys of the moon with respect to the ecliptic) froma computer program and seemed to not find any set pattern. Once you start imagining it, you basically are looking for the pattern rather than testing it. A problem I have with this is that where does it rain. The moons position will look like this over a wide area across NSW for instance. What about the inland? What type of rain does this influence? Again this is not an accurate desciption of what the farmers say as they seem to vary slightly their story. But perhaps there may be something in the timing rather than the effect of the moon on the weather. More research has to be done.

Largest ahilstone was 1.02 kg at Bangladesh on the 14.4.86 Greatest temp change in 1 day is 55.6c going from 6.7c to -49 c at Browning Montana USA. Greatest ever annual measured rainfall was at Cherrapunji in India - it was a massive 26, 461.7mm from 1.8.1860 - 31.7.1861 The island of La Reunion also holds the records for the 6hr, 12hr, 18hr, and 1 hr falls as well. -------------------------------------------------------------------------------------- Date: Sat, 31 Oct 1998 12:02:42 +1100 Subject: Re: aussie-weather: Weather and Tides From: "Mark Hardy" To: aussie-weather at world.std.com Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Jimmy This theory is related to the sunspot theory of rain prediction in a way. You may know that Lennox Walker and now Haydon Walker provide a seasonal forecasting service which (to my knowledge) is largely based on sunspot and other solar or planetary activity. I have always thought that if sunspot activity was to have an effect on earth then the impacts would be global since we are all more or less equally exposed. How does one derive very local and long term rainfall trends from data which appears to have no local relevance??

Snow to 200 metres on the Flinders in mid/late October - that sounds unbelievable. Do you have any more details on that cold snap?. The BOM monthly summaries online go back only to November 1995. What other unseasonable spring snowfalls have affected parts of Australia which rarely receive snow even in winter?. I recall, while visiting Sydney in November 1992, seeing TV footage of freak spring snow in West Australia. Here in NZ, snowfalls to low-levels are just as likely to occur in early spring as in mid-winter - the Antarctic airflows still have plenty of power. -------------------------------------------------------------------------------------- Date: Sat, 31 Oct 1998 15:53:55 +1100 Subject: aussie-weather: Aviation codes From: "Mark Hardy" To: aussie-weather at world.std.com Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Does anybody out there have an up to date listing of all the BoM stations with aviation codes mapped against WMO synop number?

I keep one which I used to have on my website, but dropped when the Bureau put their own one up at ftp://ftp.bom.gov.au/anon2/home/ncc/metadata/wmosites.lst. Unfortunately, this is not being kept up to date, and also does not include the Bureau's "aviation" codes. The Bureau also keeps fairly up-to-date lists of rainfall stations at ftp://ftp.bom.gov.au/anon2/home/ncc/metadata/sitelists/ -- it'd be nice if they kept them fully up to date, though. There's a full listing of what I am aware is available at http://www.ozemail.com.au/~wbc/4reference.html#4.3 Understanding raw data. I get a full CMSS data feed (and subscribe to SILO data), and the first I know about new stations is when my programs spit them out because there is no station catalogue entry for them, so I then either phone relevant people in the Bureau or do some detective work and establish where/what they are. I'll put my listing (somewhat modified to reduce its size) back on my web pages, and notify this list when I do. -- Laurier Williams Australian Weather Links and News http://www.ozemail.com.au/~wbc/ -------------------------------------------------------------------------------------- From: "McDonald" To: Subject: aussie-weather: Melbourne forecast and ICQ.

Do you have any more details on that cold snap?. The BOM Hi Ben and everyone, According to my Bureau of Meteorology Annual Climate Summary for 1997, there were unofficial reports of snow at Uluru (Ayre's Rock) in the Northern Territory in July. There have also been some unusual cases of snow here in Sydney although this is fairly rare. I remember back in 1986 (I think) on a July or August afternoon with strong SW winds, snow began to fall at around 5pm and lasted for around 5 minutes (pity I don't have any photos to show). The temperature was above freezing so the cloud type had a lot to do with it I think. From memory it was a tall cumulus cell that drifted over. The freezing level was probably fairly low so it wouldn't have required much of an updraught for snow and ice to form. The downdraughts were probably sufficiently cold to maintain the snow to the surface (perhaps any katabatic warming is offset by sublimation and evaporation - the clouds weren't exceptionally high either, so it might not have mattered much anyway). - Paul G. ---------------------------- Paul Graham m3052695 at hardy.ocs.mq.edu.au ---------------------------- -------------------------------------------------------------------------------------- Date: Sat, 31 Oct 1998 18:21:07 +1100 (EST) From: Paul Graham To: aussie-weather at world.std.com Subject: Re: aussie-weather: Highest Rainfall Reply-Receipt: pgraham1 at extro.ucc.su.oz.au Reply-Read: pgraham1 at mail.usyd.edu.au Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com > On Sat, 31 Oct 1998 06:51:56 +1100, Anthony wrote: > >Australia's greatest one year rainfall was 11,251 in 1979, recorded in > >Belleden Ker, QLD. - I think Mt.

I saw on NZ TV in July 1997 shots of tourists at the base of Uluru, with light snow/sleet falling, and it looked like there was a very light dusting of snow on the ground. I've never heard of snow in the Aussie outback before, but I know that there have been freak falls in the Sahara, which is in a similar climate zone. I think the rarity of snow in subtropical/desert areas is due to the fact that polar outbreaks have usually run out of moisture by the time they have reached these areas. Freak snowfalls therefore can only occur if there is a local low pressure system producing the moisture while the very cold airflow is blowing at the same time. An example of that might be the storm that brought snow to to the central Queensland highlands in July 1965. > There have also been some unusual cases of snow here in Sydney > although this is fairly rare.

Sounds like Sydney gets snow about as often as Auckland does - ie very rarely. I think snow has settled in central Auckland only once this century (1939), and even then it only dusted the higher volcanic hills of the city (about 200 metres above sea-level). -------------------------------------------------------------------------------------- X-Sender: sgamgee at mail.geocities.com Date: Sat, 31 Oct 1998 19:48:25 +1100 To: aussie-weather at world.std.com From: Ben Munro Subject: Re: aussie-weather: Highest Rainfall Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com At 07:28 PM 31/10/98 +1100, you wrote: >Paul, > >Bellenden Keer is the highest.

Perth's October record is 37.3 Notham's hottest October temperature is 39.3 which is the composite record Mount Barker's is 35.6, which is also the composite record Some clouds developed over the hills during the mid afternoon and by late afternoon low level cloud in the SW airstream started to move through.
