Abstract

In this study an attempt has been made to evaluate long-term average variation and fluctuation of Seasonal wind in Iran. For this purpose wind database network was initially formed over Iran. Then data from the base of a 30-year period the daily period of 1011982 to 31122012 was supposed as the basis of the present study and a cell with dimensions of 15 15 km of the studied area was spread. In order to achieve the wind seasonal changes in Iran modern methods of spatial statistics such as Moran global spatial autocorrelation Moran Local insulin index and Hot spots by using of programming in GIS environment were accomplished. The results of this study showed that the spatial distribution of wind in Iran has the cluster pattern. In the meantime based on Moran local index and Hot spots wind patterns in the South South-East East South West and North West have spatial autocorrelation positive pattern and parts of the Caspian Sea coast north and center of the country have negative spatial autocorrelation. During the study period a large part of the country almost half of the total area had a significant pattern or spatial autocorrelation.
