The performance of medium range forecast is verified and compared for the models of T639, ECMWF and Japan from June to August 2012. The results show that the three models have good performance on predicting the variation and adjustment of atmospheric circulation over Asian middle and high latitude areas. Comparatively speaking, EC has better performance on forecasting synoptic systems and elements than T639 and JP models, and is the best at the prediction of the track and intensity of typhoon Haikui among all models.
