Estimating maximum wind speed is an essential task in many fields of environmental and engineering risk analysis. This study used prevalent westerly annual maximum wind speeds for the period of 1983-1998 for East Isfahan station in Isfahan Province, Iran. The frequency analysis of AM data wind speeds obtained by averaging the wind data over some chosen averaging periods showed that extreme value Type I distribution is the best distribution for 15, 30, 60 and 120 min wind durations. The frequency and average corresponding duration were then plotted. This plot gives the average wind duration and speed for any given return period. (c) 2007 Elsevier Ltd. All rights reserved.
