Abstract

Increasing greenhouse gases could increase the frequency of changes in precipitation in different regions of the world. So, identify the effects of global warming on precipitation in a country like Iran which is located in the dry area of the earth is of great importance in planning related to water resources are. According to the study, statistical analysis method used. for analysis, total precipitation data of 34 stations from 1984 to 2012 was received from the National Weather Service. Also data of methane Gase (ppb) as one of the most important factors of global warming, the site of NOAA received. Outset this elements by method The Pearson correlation coefficient determined, afterwards long-term changes in precipitation than was calculated. The results of this study showed that, Bharhdr rainfall in the north and northwest parts of the country grew 13 mm; and Precipitation stations southern half of the country have faced long-term reduction of 46 percent. Due to the increasing amount of greenhouse gases, analysis of the data suggests a reduction of 30 mm of precipitation in summer than long-term stations in southern Iran, but in contrast rainfall in western and northern stations, an increasing of 14 mm. The results showed that the autumn precipitation is most relevant to global warming, in this season, about 24 mm of rainfall western stations to long-term decline, but the Southwest and Southeast stations surged 17 mm have experienced. Finally, the results of the Winters precipitation showed which, the West and Northwest stations were reduced 18/6 mm.
