为更好地应用T639模式中期预报产品,对2009年9-11月T639模式96小时预报产品进行了天气学检验,并与ECMWF、日本模式进行了对比分析.结果表明:3种模式均对亚洲中高纬环流形势的调整和演变具有较好的预报性能.综合来看,ECMWF模式埘符系统及要素的预报最接近实况;日本模式和T639模式次之;ECMWF模式对0917号热带风暴芭玛(Parma)的预报较为成功,T639模式稳定件较差,而口本模式对"芭玛"的预报无论是路径还是强度都存在较大偏差.
為更好地應用T639模式中期預報產品,對2009年9-11月T639模式96小時預報產品進行瞭天氣學檢驗,併與ECMWF、日本模式進行瞭對比分析.結果錶明:3種模式均對亞洲中高緯環流形勢的調整和縯變具有較好的預報性能.綜閤來看,ECMWF模式塒符繫統及要素的預報最接近實況;日本模式和T639模式次之;ECMWF模式對0917號熱帶風暴芭瑪(Parma)的預報較為成功,T639模式穩定件較差,而口本模式對"芭瑪"的預報無論是路徑還是彊度都存在較大偏差.

In order to improve the ability to use the products of T639,some synoptic verification on its medium-range forecasting in 2009 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 largescale circulation evolution and adjustment in Asian middle and high latitude areas.As a whole,ECMWF model is better in forecasting most weather systems compared with the T639 and Japan models.Taking tropical storm No.0917(Parma)as a case,it is found that ECMWF model gets the most correct results,and that T639 model has poor stability,whereas Japan model completely failed in forecasting the track and the intensity of Parma.
