Abstract

Having a correct view of the effective factors on climatic changes by explanation of a considerable part of the total variance in data with limited number of PRINCIPAL COMPONENTs the analytical methods of decreasing data dimensions, such as PCA are important tools in water resources planning. In this study FACTOR ANALYSIS method as a tool for projecting the information space on the limited and specific axes, has been applied. The main aim of this study is regionalization of URMIA Lake basin from the view of DROUGHT using FACTOR ANALYSIS. For this purpose monthly precipitation data of 30 weather stations in the period 1972-2009 were used. For each of the selected stations three and twelve months SPI value were calculated. FACTOR ANALYSIS conducted on SPI values to delineate the study area with respect to DROUGHT characteristics. Homogeneity of obtained regions tested using the Sstatistics proposed by Wiltshire. Resultes of FACTOR ANALYSIS of 3 (12) months SPI values showed that 5 (6) factors having EIGEN VALUEs greater than 1 acounted for 68.08 (78.88) percent of total variance. URMIA Lake basin delineated to 5 (6) distinct regions considering the eigenvectors following rotation using the 3 (12) month time scale. Results of homogeneity test indicated that all of the obtained regions were homogeneous.
