Abstract:
In order to improve the ability to use the products of T639, some synoptic verif ication about its medium-range forecasting for 2008 autumn is made in comparison with the NWP of ECMWF and Japan models. The results show that the three models have good performances in the aspect of predicting the large-scale circulation e volution and adjustment in Asian middle and high latitude area, and they all sho w significant indication to forecast the transition and the weather disaster. As a whole, ECMWF model is better in forecasting key weather systems compared with the T639 and Japan models. Especially, T639 and Japan models have failed in pre dicting path and intensity of strong typhoon HAGUPIT, whereas ECMWF model are re latively accurate.
