Climatic Zoning of South Khorasan Province With GIS Software

Climatic classification of geographical areas from the distant past has been done. With the difference that in the past the traditional methods and GIS technology today with the advancement of modern methods are used. As well as the use of multiple climatic parameters in traditional methods alone would not be cardiac regions climate reality. Therefore, in recent years, researchers have tried to use the number of parameters affecting climate and more modern methods, real climate regions of the video provider. The purpose of this article the climatic regionalization of southern Khorasan Province with the method of factor analysis and cluster and Spatial Autocorrelation and more climatic elements in determining the type of weather for the area to be incorporated.To improve the results of climatic regionalization of synoptic meteorological stations facts and climatological was used. For this purpose a matrix 34 * 11 Includes 7 synoptic station and 4 climatological station. The results of this analysis showed that climate affected province of 6 factors in order of importance are, Temp (temperature), humidity of the atmosphere, windy- dust, Frost, rainy, sunny (radiation). The exercise component of about 96.5 percent of the interpretation of climatological behaviour. Cluster analysis on the factors mentioned there are 6 region of air and water in the province showed. Semi-warm and dry temperate zone, Hot and arid area, Hot and dry semi-desert area, Cold and semi-arid mountainous area, Wilderness area, Hot and dry desert area
