摘　　要：根据月时间尺度上的降水与大气环流之间的关系 ,利用国家气候中心 T6 3模式动力延伸预报产品 ,应用卡尔曼滤波方法对月时间尺度上降水进行了预测试验。结果表明该种模式动力产品释用方案在短期气候预测中具有较好的应用前景。According to the relationship between monthly rainfall and monthly general circulation and making use of dynamical extended range forecast products of National Climate Center′s T63 model,Kalman filter method was applied to attempt the monthly rainfall prediction.The result indicates that reexplanation and reanalysis of model dynamical products in this way have a good applied prospect in short range climatic prediction.
