Abstract

Considering the importance of wind factor in wind erosion, it can be used as one of the major factors in determining the power of the wind erosivity. Extreme WIND SPEED estimation is usually important in many fields of environmental studies such as climatology, hydrology, agricultural management and structure designing. Therefore it is important to estimate distribution function of wind velocity. WIND SPEED data are however often not available or attainable in short term period. To solve this problem, Linear moments analysis was used in this research. This method can determine the regional distribution function in a region, which in turn reduces the statistical uncertainty in the stations with short term period data. Monthly averages of maximum daily WIND SPEED of 26 meteorological stations in YAZD PROVINCE were used for regional analysis in this research. Based on L-moments analysis, the study area is divided to five homogeneous WIND SPEED regions. The results indicated by statistical tests DISCORDANCY MEASURE, heterogeneity measure, goodness of fit measure showed that the Generalized Logistic (GLO) distribution model was the best regional distribution models for 3 HOMOGENEOUS REGIONs.
