摘　　要：本文运用欧洲中期天气预报中心的数值预报产品，组成平均高度场，通过具有耗散强迫低阶动力学系统的控制方程，作随机动力处理，对有限区域５００ｈＰａ高度场作下一旬的平均高度场预报，经试验证明其结果能给中期预报提供依据。The numerical forecasting products made by the European Centre for Medium-range Weather Forecast are used to form the mean height fields.Using the governing equations of low order dynamics system with dissipative fouce,we made the prediction of the mean 500 hPa height fields of limited range for next ten days.The experiments,prove that the results could be a useful basis for mid-range weatherforecast.
