Abstract:
It was verified and compared that the performance of T639, ECMWF and Japan models about their mediumrange forecasting during Dec. 2009 to Feb. 2010. The results show that the three models have good performance for the evolvement and adjustment of atmospheric circulation situation and the temperature trends of in the lower troposphere in Asian middle and high latitude areas. Compared with the EC model, T639 and JP models have some larger errors for the forecast of trough in the Bay of Bengal. For the high pressure of cold wave, EC model has the best performance for the location and strength of cold anticyclone central， T639 model is better than Japan model in the aspect.
