Abstract

Wind speed is one of the most complex meteorological parameters in a specific region Furthermore, climate behavior in an area is influenced temporally in short and long terms. In the present study, Mann-Kendall and Petit nonparametric tests were applied to analyze the trend of monthly and annually wind speed data series in four synoptic stations of Lake Urmia (Tabriz, Urmia stations with 50 years, Mahabad and Sahand with 28 years). The results of the aforementioned tests, based on annual and montly scales, showed that the average wind speed at all stations has an increasing trend at 99% confidence level. However, the concerned years were not appeared to be quite identical in all stations. These changes occurred at Mahabad station in 2000 and at other stations in 1995. Also, the wind speed increased at Mahabad station in winter and at other stations in spring and summer.
