Application of Error Correction in Forecast Ensemble

In consideration of the error comprised of systematic and random error, the error analysis of the May rainfall forecast of several methods in Baoshan, Yunnan Province is made. And first, the systemic error correction method of each forecast technique is found out, to reduce its effect. Then, the corrected forecast is averaged, to eliminate the random error. The results show that mean error and mean square root error decrease obviously, and the forecast accuracy is improved obviously.
