Abstract

Rainfall is the most variable climatic elements. The changes occur in the location and the time dimension in the form of regional climate. The purpose of this study was to investigate the SPATIAL AUTOCORRELATION of IRAN's heavy and super heavy changes. For this purpose, the daily rainfall data of 664 meteorological stations during the period 1950-2010 have been used. In order to analyze changes in rainfall within a decade, geostatistical techniques such as SPATIAL AUTOCORRELATION analysis of hot spots, statistics Getis-Ord Gi along with programming in Matlab environment and the Surfer and the GIs were used. The results of this study indicated that the Caspian coast, North West and West along the western foothills of the Zagros Mountains of IRAN, the inner regions of IRAN and southern parts of South East and North East of IRAN had the highest precipitation of heavy and super heavy requirements. Spatial pattern of heavy precipitation showed that the maximum positive SPATIAL AUTOCORRELATION pattern of heavy precipitation, despite their different periods of oscillation, but includes areas of West, North West and West coast of the Caspian Sea. While this is a negative SPATIAL AUTOCORRELATION pattern of heavy precipitation, it is observed frequently in central IRAN and parts of the East, particularly in Zabul. Patterns of heavy precipitation are similar to heavy precipitation.
