Investigation of spatiotemporal behavior of annual precipitation based on EOF and fuzzy EOF: Ghazvin Province area

Introduction: The pattern of annual precipitation in developing areas and the related industries is known as one of the most important infrastructure in such studies. This investigation is based on statistical analysis of the frequency of the total annual amount of precipitation using Empirical Orthogonal Function (EOF). The long time statistical studies support the effectiveness of the implemented statistical EOF in the area. Fuzzy logic is a new fold of logical reasoning that is estimated rather than a fixed and exact * ﻂﺑار هﺪﻧرﺎﮕﻧ
