Climatic Regions of Fars Province

The recognition of regional lands of Fars province due to their vast expanses for planning purposes of various dimensions (local, regional, national) is of great importance. This research has studied the recognition of climatic regions of Fars province. In order to reach our goal, 25 climatic variables in relation to moisture, heat, precipitation and radiation were used from 18 synoptic meteorological stations. Afterwards, a factor analysis method based on the principal components of the regions and a clustering analysis method in acompound model were used for separation of stretched lands. The study of climatic variables on the basis of principal components analysis showed that there were 3 principals in the climate of Fars province. These principals, in order of importance, are: thermal principal, precipitation principal and principal of summer precipitation, respectively. A clustering analysis on factor amount helped dividing this province to four climatic regions: southern, western, central and northern areas.
