Abstract

In this research it was tried to regionalize IRAN'S CLIMATE using multivariate techniques, like to define special characteristic of each climate. To do this we first collected datasets consists of 123 climatic and geographic variables from 77 weather stations all over of the country. After complete the missing data, ten variables were selected out of 123 using PROCRUSTES method. These selected variables used to grouping stations using FACTOR ANALYSIS and CLUSTER ANALYSIS with Ward's method. Results show that the first two factors contain over 88% of variation in the datasets. So these two factors considered as dominant factors. Factor scores after rotation calculated for 77 stations. These scores then used to as an input matrix (77*2) for CLUSTER ANALYSIS. All of sites classified into seven groups with respect to obtained dendrogram. In addition discriminate function analysis used to assessing the performed climate regionalization of the country. Results show that over 92% of sites classified by correct manner. So it can be said that results of regionalization performed by mentioned method, can then be used to following various studies like agriculture (especially dry farming), irrigation and so on.
