Abstract:Actually, the products of numerical forecast have been broad applied to weather forecast operation in China. In order to improve the ability to use the products of T213, ECMWF and Japan models, the performance of T213, ECMWF and Japan model s for 96h mediumrange forecasting during the period from June to August 2007 w as verified and compared in the paper. The results show that the three models have a good performance in aspect of predicting the largescale circulation evoluti on and adjustment in Asian middle and high latitudes. As a whole, ECMWF model is more classic in forecasting most weather systems compared with the T213 and Jap an mo dels. Especially, T213 model has a large error in predicting path and intensity of typhoon SEPAT, whereas ECMWF and Japan models are relatively accurate.
