Abstract:
Using the singular spectrum analysis method,the features of summer precipitation nearly one hundred years in Shijiazhuang city are analyzed.The results show that the feature of tendency variation of summer precipitation is not marked,main oscillation periods are 5-6 years,about 10 years and 30-40 years respectively,and time variables (amplitude and phase) of rebuild arrays are characterized by interdecade.The prediction result of summer precipitation based on the rebuild arrays during 1998-2001 are better.
