Extreme Wind Prediction – The Australian Experience
The extreme wind climate of Australia is discussed with a description of the available historical data recorded by the Bureau of Meteorology. The necessity of correction of gusts for gust duration, and for terrain, and for separating the data into storm type is outlined. The ‘bootstrapping’ technique for assessing sampling errors and confidence limits is also discussed. As examples of the methods discussed, recent data from three locations in South Australia were processed. These illustrated the mixed climate near the southern coastline, and the dominance of non-synoptic downdraft winds at a northern station far from the coast.
