The performance of T639, ECMWF and Japan models about their mediumrange forecasting during December 2011 to February 2012 was verified and compared. The results show that the three models all have good performance on predicting the largescale circulation evolution and adjustment over Asian middle and high latitude area and the temperature trends in the lower troposphere. ECMWF model is the best at forecasting westerly wind index and 850 hPa temperature. With respect to forecasting of trough in the Bay of Bengal, ECMWF model has the best performance, while the forecasts by T639 and Japan models are both weaker than their initial fields. The three models predict the weak surface high, and the errors of Japan model is the smallest while those of T639 and EC models are comparatively larger.
