Nowadays researchers are paying due attention to climatic parameters in order to offer justifiable grouping for farm products cultivation areas. Accordingly, the influence of climatic factors has already been proven in regard with the regionalization of vineyards. Although the temperature parameter has been emphasized so far, it seems that relying on single-parameter techniques has not been such effective in regionalization. Based on such an assumption from quantities of monthly minimum temperature, maximum temperature, precipitation, relative humidity, mean wind speed, and besides amount Penman potential evapotranspiriation in 45 synoptic stations of Iran in January-September from 1985-2005 that according SCI. Organization site were grape-growing regions, 3 index "Huglin's heliothermal, cool night, potential water balance index of Riou" have been calculated. These indices are representative of variability of viticultural climate of Iran. Then 16 climatic groups of grape-cultivation areas were identified using Tonietto and Carbonneau (2004) technique and their specifications were studied. Central and eastern regions of Iran were included in the hot region with hot nights and high aridity; while other regions enjoyed climatic variations. Based on the patterns introduced in this paper, it is possible identify new areas with higher potential for grouping grapes and achieving the highest yield in production, using different varieties of the cultivated grapes in different climatic areas.
