The mediumrange forecasting performances of T639, ECMWF and Japan models from December 2015 to February 2016 are verified and compared. The results show that all of the three models can predict the variation and adjustment of the atmospheric circulation over Asian middle and high latitudes well, of which the performance of ECMWF model is the best. For temperature at 850 hPa, Japan model's mean forecast error is smaller than the errors of other two models. ECMWF model forecasts higher temperature for both the northern and southern parts of China, while T639 model produces a lower temperature forecast for northern part of China. For the surface high forecasting during the nationwide cold wave process in January 2016, T639 model performs much better in forecasting the intensity of cold high than ECMWF and Japan models, which underestimate the intensity in most time.
