In order to understand the efficiency of the products from a mediumrange forec asting model, the performance of T213 model for 96hr mediumrange numerical for ecasting was verified during the period of Dec. 2007 to Jan. 2008 comparing with ECMWF model and Japan model.The result shows that the three models all have go od performances for evolution and major adjustment of the largescale circulati on pattern in Asia high and middle latitude area. ECMWF model is better than the othe r two models for forecasting westerly index,the temperature of 850hPa,the circul ation of 500hPa and southern branch trough, especially the event occurred during 10th-16th Jan. 2008, but the T213 model and Japan model have errors in terms of the precision of the intensity,position of the main system.
