Abstract:
In order to improve the ability of using the products of T639, a synoptic verification on its medium range forecasting prodcuts in autumn 2013 is made, and then compared with the NWP of ECMWF and Japan models. The results show that all the three models have good performances on the aspect of predicting large scale circulation evolution and adjustment in Asian middle and high latitude areas. As a whole, the ECMWF model is much better in forecasting most weather systems compared with the T639 and Japan models. Taking the strong tropical storm No.1319 (Usagi) process during the period of September 20-22, 2013 as a case, it is found that the ECMWF model is more effective than the other two models in medium range forecasting of the turning track of USAGI and its landing point.
