| 摘 要： | 为了优选考虑新疆气候和地形特征的背景场和物理过程,设计WRF模式的Lin、WSM6、Thompson微物理过程和KF、Grell 3D积云参数化敏感性试验方案,使用T639和GFS两种背景场,进行了回算和对比检验,确定了在新疆预报能力最优的物理过程和背景场方案,并对WRF模式在新疆的预报能力和不足之处有了较为清晰的认识。

| Abstract: | WRF model system is a new generation mesoscal numerical weather forecast model and data assimilation system which is development by meteorological community of U.S.A, widely applied in operations of meteorological service so far. For select background field and physics progress that suitable to Climate Topographic Characteristics, By comparing the result of sensitivity test about microphysics and cumulus parameterization of WRF models , and T639 and GFS as background field, background field and physics progress have best performance in xinjiang was defined. At same time, forecasting performance and shortcoming of WRF models in Xinjiang is revealed . |
