Abstract:
The performances of medium range forecasts are verified and compared for the T639, ECMWF and JP models from June to August 2014. The result shows that the three models have good performance on predicting the variation and adjustment of the atmospheric circulation and 850 hPa temperature over Asian middle and high latitude areas. In contract, ECMWF model has better performance than T639 or JP models. Both ECMWF and T639 models have good performance on predicting western Pacific subtropical high while they still have some bias at some time. T639 model is the best at the prediction of the track and intensity of typhoon Rammasun among all three models, and the forecasting intensity of ECMWF model is weaker than that of the observation.
