摘　　要：本文利用一个全球谱模式（T63L9）和1994年4个时段个例的全球客观分析资料探讨了中期数值天气预报的误差订正方法。个例分析的结果表明，采用定常误差订正和时空平滑误差订正方法，误差订正效果显著，可考虑在业务系统中采用。With a global spectral model (T63L9),a error correction method for medium range weather forecasting has been studied using initial fields of four time periods in 1994.The case analyses show that error correction effect is obvious by using stationary error correction method and spatial and temporal smoothing error correction method. It is suggested to be used in forecast system.
