The model calculates the return period of severe winds based on daily maximum wind gust observations. The model utilises an automated procedure to partition the data into the hazard constituents (thunderstorms, synoptic winds, tornadoes, etc) based on the World Meteorological Observation Codes 3-hourly coded observations. This observational data set records the archived and present weather at the station site. The model fits the GPD to the station data (daily maximum wind gust) by automating the selection of the appropriate threshold above which data is included in the extreme value distribution. This threshold u is selected as the maximum of all feasible return period values obtained by fitting the GPD. Published comparative findings, including same region results, demonstrate the model can produce similar results in a more efficient, fully computational way. Confidence intervals for return periods are calculated automatically to allow wind analysts to distinguish regions of greater reliability. {"type": "Polygon", "coordinates": [[[149.2, -35.3], [152.15, -35.3], [152.15, -30.76], [149.2, -30.76], [149.2, -35.3]]]} 149.2 152.15 -35.3 -30.76 Earth Sciences GA Publication Published_External Record model wind Download the Record (pdf) documentDigital Download the Record (pdf) PDF Unnamed resource documentDigital HTML
