Abstract:
In order to improve the ability to use the products of T213 model，the performance of T213 model for 96hr mediumrange numerical forecasting was ver i fied during the period of Dec. 2006 to Jan.2007comparing with ECMWF model and Ja pan model. The result shows that the three models have good performances for evo lvement and major adjustment of circulation pattern in Asia middle and high lati tude area, therefore, they can forecast the severe disaster weathers ahead. By c o mparing three models, the product of ECMWF model predict well for forecasting of westerly index, temperature of 850hPa and southern trough, but there are some s ystem errors among the three model in forecasting temperature of 850hPa. Japan m odel is much better in forecasting surface pressure than T213 and ECMWF model.
