and was analyzed for that period in order to develop a mathematical model to predict the weather parameters for the next ten years. Weather prediction is one of the most difficult tasks in operational meteorology. There are several weather forecasting methods such as statistical methods and Numerical Weather Prediction (NWP) models [12] and [20]. Because of the nonlinear characteristics of weather parameters such as rainfall process, statistical methods cannot generate good results. Local climate situations can also extremely affects the rainfall generation process. And the NWP models cannot solve this local problem.
