Maleny Weather

The tropical Pacific Ocean sea surface has continued to warm in central and eastern areas, with a typical El Niño pattern clearly present. The central Pacific has now warmed to a level that has not been observed since the 2002 El Niño.The sub-surface water of the tropical Pacific has also continued to warm, with temperatures as much as 6°C above normal in some regions.The latest approximate 30-day SOI value is −15; the monthly value for October was also −15. The SOI has recently stabilised after a rapid fall in value through October.Following a sustained weakening of the Trade Winds during October, a pulse of average or stronger than average Trades is developing in the western Pacific.Cloudiness near the date-line has been slightly below average in recent weeks. However, cloudiness to the west of the date-line has been consistently above average, as also occurred during the 2006 El Niño and to a lesser extent in the 2002 event.Most leading international computer models surveyed by the Bureau predict that El Niño conditions will persist throughout the southern hemisphere summer.

*Noosa Bush Fires

Maleny missed out on the showers and thunderstorms generated from  an upper level system  over most of  Queensland, and the small amount of rain we did have came from some isolated maritime showers brought in over the coast on the trade winds.  With record breaking November temperatures and a heatwave in SA we are fortunate in so far keeping to our month’s mean temperatures and well below our past peak of 34.7ºC on Nov 29^th 2006. On Friday smoke from a bush fire was trapped overnight by a temperature inversion.

People in Norfolk (UK) with respiratory problems are to be sent reports on weather conditions which may affect their health. The Healthy Outlook service telephones weather-related warnings to patients in Norwich with chronic obstructive pulmonary disease (COPD). National Health Service (NHS) Norfolk said the pilot is aimed at reducing hospital admissions. COPD patients find that humidity, air pollution and changes in temperature can affect their condition.The service works by making an automated telephone phone call to registered patients in advance of changing weather patterns, NHS Norfolk said.

Adelaide’s extreme hot weather is now officially in the record books as the city’s first heatwave for November.There have been five days in a row above 35 degrees Celsius.Simon Timcke from the weather bureau says history was made before lunchtime today Nov 12″Shortly before 11 this morning we clicked over 35 degrees which makes it the first official heatwave in November in Adelaide,” he said.The previous hottest run was four consecutive days above 35 degrees in 1894.On Wednesday 26^th November 1997 heatwave conditions prevailed in Victoria and South Australia when hot desert winds moved south to blow away all previous November records. The hottest place at that time was Ceduna in SA with 46ºC, a November record. Likewise, Canberra was another record breaker with 38.9ºC. This heatwave was caused by a high pressure system in the Tasman Sea and a low pressure system to the west. Winds from both systems combined to bring a vortex of hot air drawn down from the north.
