Natural characteristics of each area, especially the climate, plays a major role in planning and development. Chaharmahal and Bakhtiari is a province that located in the south-west mountainous region of Iran. Due to topography diversities, this region has a different distribution of climatic elements (especially, rainfall and temperature). In this study, the multivariate statistical methods such as factor analysis and cluster analysis were used to detect sub-climatic regions of this province. For this purpose, 26 climatic variables were collected from 6 meteorological stations in the province. For overcoming the lack of climate control stations throughout the area the IDW Interpolation technique was used to produce a data matrix with dimensions of 26 × 46 (variables× nods) and it considered as a database for factor analysis. The results of factor analysis on the produced data set showed that four major factors which affect the climate of the province in order of importance are: the precipitation, the clear sky, the temperature and the humidity. Finally, cluster analysis on the matrix of factor scores recognized the four climate zones throughout the province.
