【Abstract】 Four kinds of approaches were introduced.They are of synoptic pattern,MAPS numerical model,artificial neural network and Japanese numerical model for forecasting area rainfall in the Sanxia region and analyses impact of the experiment during the summer in 1999.Results show that the forecasting effects are better for artificial neural network and MAPS numerical model.Finally improving measures are given for the first three kinds of approaches.更多还原
