中文摘要: 作者简单介绍了国内预报员较为熟悉的欧洲中期天气预报中心、美国国家气象中心和日本气象厅三个中期预报模式的性能及预报效果，包括近几年颇为流行的半拉格朗日时间积分方案，物理过程参数化方案的完善和改进，中期数值预报业务模式的发展趋势等。
中文关键词: 中期数值预报业务模式，物理过程参数化，模式性能，预报效果
Abstract:The characteristic and performance of the operational medium range numerical weather prediction models is described, abroad which widely used by forecasters and have a very good reputation in China, such as ECMWF,NMC(USA) ,JMA. It mainly includes the Semi-Lagrangian time integration scheme receiving most attention at this time, the improvement of the physical parameterization package, etc. The outlook of the global model in the future is given.
