【Abstract】 In this paper, a mathematical model, which is for the prediction of rainfall in Beijing region, is obtained through analysis of relationship between variation of rainfall and temperature in Beijing region since 1900 and solar activity and E1 Nino. The rainfall in the region in 1996 and 1997 has been predicted exactly. The rainfall in the region in 1998,750mm～800mm, is predicted.更多还原
