Behavioral Analysis of Micro-climatic Regions in Central Iran Using Factor Analysis Method

The zoning of sub-regions and the recognition of the most important factors and elements affecting each area is one of the ways of recognizing the climate identity of the micro-climatic regions. Climatic zoning was carried out with the help of statistical methods such as factor analysis and clustering to obtain an accurate and comprehensive understanding of the central regions of Iran. To this end, 15 climatic variables were selected from 15 central synoptic stations. The results of the study by factor analysis showed that the climate of the studied area is affected by four factors, which are important, namely rainfall, temperature, humidity and thunderstorm. Among all extracted climatic factors, rainfall factor with explanation of 35.08% of total data variance has the most important role in determining the micro-climatic region conditions in the area. In total, these four factors have explained about of climate behavior in central Iran. The results of cluster analysis revealed four micro-climatic regions in the study area on the four climatic factors.
