The performance of medium range forecast is verified and compared for the models of T639, ECMWF and Japan from September to November 2014. The results show that all the three models have good performance in predicting the variation and adjustment of atmospheric circulation over Asian middle and high latitude areas and the transition of temperature at 850 hPa. They also have good performance in predicting ridge line position of western Pacific subtropical high, but the deviation of EC is the smallest. EC is the best at forecasting the track and intensity of typhoon Fung wong among all the three models. EC and T639 can forecast fog and haze, but EC does even better than T639.
