Analysis of spatial variability of climatic components of Isfahan province using Factor-Cluster Analysis

The purpose of this research is to identify the change of climatic components of spatial zones in Isfahan province. In this study, by using factor-cluster analysis has done climatic regionalization of the Isfahan province. This method selected for all climatic variables influencing in the climatic regionalization, for implementation this study, the wrought matrix for selected stations and parameters affecting the climatic, at size 29 * 24, including 24 synoptic stations in the province and adjacent areas, and 29 parameters were affecting the climate. Due to the nature of the research were used normal annual data for analysis and because of differences in scale variables measured were used of the standard value variables. Also from IDW Interpolation methods for creating nodes and the kriging method was used to create arenas. Results of the factor analysis showed that the five factors Height-Coldness-Precipitation, Thunder-Precipitation, Cloudiness-Humid, Humid and Dust more than 92% of can explain the behavior of climatic of the province. Using cluster analysis on the factors mentioned in Isfahan province was divided into seven climatic regions.
