From early ages, regionalizing and classification have been noted in all scientific views of geography, especially climatology. For precipitation zoning of KurdistanProvince, the monthly data of 28 synoptic stations and rain gauge stations were used for a period of 15 years. Using cluster analysis with the Ward's technique, precipitation regions of KurdistanProvince were determined. The results from this analysis specified three different regions in this province that were called the central moderate precipitation region, the east low precipitation region and the west high precipitation region. The central moderate precipitation region was the biggest precipitation region in KurdistanProvince. Annual precipitation of this region reaches about 455.8 mm. A high proportion of the precipitation in this region occurred in winter; thus, it indicates a winter regime. The east low precipitation region is the second region with the highest amount of precipitation in KurdistanProvince; annual precipitation of this region is about 323.4 mm and most precipitation of this region happens in spring; therefore, it has a spring regime. The west high precipitation region includes the least region and, at the same time, it was the region with highest amount of precipitation in KurdistanProvince. The annual precipitation of this region was about 837 mm and it is considered as the winter regime precipitation.
