Abstract:The results show that all of the three models can predict the variation and adjustment of the atmospheric circulation over Asian middle and high latitude areas well, of which ECMWF model performs the best. The ECMWF model has a good performance in predicting the activity of western Pacific subtropical high, while the prediction of T639 model shows some biases compared with the observation. The three models can predict the persistent hightemperature in Xinjiang in July 2015 well and the prediction for 850 hPa temperature is a little higher than observation in Northern China. For Southern China, the three models have smaller biases in temperature prediction than for Northern China, and the ECMWF model has better performance than T639 and Japan model. As far as Typhoon Soudelor (No.1513) in concerned, T639 model performs better in predicting its track and landing position, although the predicted intensity is a little higher. The predicted landing time of Soudelor by ECMWF model is earlier than the observation.
