Identification of precipitation patterns on Chabahar Coastal

The location of Chabahar coastal areas on the development circuit requires knowledge of the environmental characteristics of this area for comprehensive planning. The genealogy of flood risk is very important for executives in planning and preparing the coast. One of the main drivers of floods on rainforest shores is that by identifying its behavior, floods can be managed Precipitation is one of the most variability climatic elements that it has complex behavior, spatially in arid and semi- arid arias. Therefore investigation of precipitation characteristics in a region has significant effects on the environmental planning. The recognition of precipitation characteristics of a region, its monthly and seasonal distributions, intensity, duration and amounts can result to determine the different types of precipitations patterns in a region. In this paper by using the daily precipitation data of Chabehar synoptic station (during 1985-2013) 280 rainy days from total days (4817 days) was obtainedFinally by applying a cluster analysis on the 183 rainy clusters in a 183*4 matrix, five patterns of precipitation types was recognized and the characteristics of these types were analyzed.
