中文摘要: 针对2006年12月至2007年1月T213 模式96小时中期数值预报产品进行了天气学检验
，并与ECMWF、日本模式96小时预报性能做了对比分析。结果表明，T213、ECMWF、日本模式
对亚洲中高纬度地区大尺度环流形势演变和重大调整过程均有较好的预报能力，因此对重大
灾害性天气的预报有较好的指示意义。三种模式相比，ECMWF模式对西风指数、850hPa温度
、南支槽东移的预报较为准确。
Abstract:In order to improve the ability to use the products of T213 model，the
performance of T213 model for 96hr medium range 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.
