Assessment of the relations between the surface meteorological parameter changes and the spring rainfall of Khorasan-e Razavi province

The researches show that global climate changes and atmospheric general circulation are affected by large scale phenomena that occurred in the sea surface. These large scale phenomena are often called the climatic large scale signals. These signals are calculated based on criteria such as Sea level pressure (SLP), Sea surface temperature (SST) and etc. One method for weather forecasting is a special approach based on statistical modeling. In this research, the Kriging method was used to obtain average regional rainfall. Average data of 38 rainfall stations were used to obtain the relation between precipitation and precipitable water, zonal wind and meridional wind in the Khorasan Razavi province. The results show that significant relationships exists between rainfall and meteorological parameters and we can successfully use these parameters to determining of dry and wet seasons in the area under study.
