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。
For optimizing background field and physics progress of WRF model that are suitable toclimate topographic characteristics in Xinjiang, the results of sensitivity test about Lin,WSM6,Thompson microphysics and KF,Grell 3D cumulus parameterization of WRF models, are designedand compared applying T639 and GFS as background field. The background field and physicsprogress which have best performance in Xinjiang was defined. At the same time, forecastingperformance and shortcoming of WRF models in Xinjiang is revealed.
