Three typical large-scale autumn rainfall fields are obtained by use of empirical orthogonal expansion and causes of the large-scale autumn rainfall anomaly are analyzed. It is pointed out that there is a close relation between the anomalies of the autumn large-scale precipitation in China and the Southern Oscillation/El niño. The Southern Oscillation is used as the predictor and the autumn rainfall data from 1951 through 1984 are reconstructed by the statistical methodResults show that the average absolute error is only 0.70 of the mean square error. Trial forecasting made for 1985 and 1988 is quite satisfactory.
