中文摘要: 为更好地应用T639模式中期预报产品，对2009年3—5月T639模式进行天气学检验，并与ECMW
F和日本模式进行了对比分析。结果表明：T639和ECMWF模式及日本模式预报性能均较好，相
对地，ECMWF对中高纬大气环流的演变及850hPa温度有较强的预报能力。选取2009年4月23—
25日的沙尘天气个例，T639模式对于引发此次沙尘天气的地面强风的中期预报指示意义最好
，日本模式次之。
Abstract:In order to better apply the medium range forecast products of the T639 model，
s
ome synoptic verification from March to May 2009 are made in comparison with ECM
WF and Japan models. The result shows that three models all have good forecastin
g performanes. Comparably, the ECMWF is better than T639 and Japan models
in forecasting the evolution and modification of the atmosphere circulation in
middle and high latitude, and the trend of temperature in 850hPa. Taking the
sandstorm process during the period of 23-25th in April as a case, T639 mo
del can predict well in aspect of forcecasting surface strong wind in the proces
s of the sandstorm compared with Japan and ECMWF models.
