Abstract

The analysis of the rainy season characteristics such as the rainfall onset, cessation and different length of dry spells between precipitation occurrences is one of the important issues in agricultural arenas. Daily rainfall data of Mashhad Station from 1961 up to 2008 have been used to determine these parameters. The onset date has been calculated by 7 different methods that some of them are based on cumulative rainfall amounts and the others are based on relations of rainfall and potential evapotranspiration. At last a hybrid method has been presented being qualified to determine this factor. Furthermore we have specified the occurrence of false starts by determining of false start definition. The cessation date was defined by 2 methods and after that the length of the growing season have been calculated by using hybrid method for determining onset date and second method of specifying cessation date. Based on these calculations the rainy season will start at 27th November in Mashhad and the length of rainy season will be 185 days. Finally the effects of CLIMATE CHANGE on characteristics of rainy season have been detected that it showed the CLIMATE CHANGE haven’t had any serious effect.
