中文摘要: 使用NCEP再分析资料作为大尺度背景场,在9km网格距下,应用MM5V3.5对陕北地区的夏季降水和冬季降温进行了模拟试验,结果发现MM5V3.5对该地区夏季区域性降水分布型态、演变过程以及冬季降温过程具有很好的模拟能力,对局地性极强的降雨模拟能力较差,对降水中心的模拟存在一定的偏差,大范围的区域性降水模拟有虚假中心出现。

Abstract:Three cases are chosen to verify the MM5V3.5 model′s simulating capability for meso-scale system in the north of Shaanxi province. The results indicate that at 9km resolution and NCEP as the large scale background field, the model has the best ability of simulating the pattern of summer rainfall and evolution features except some deviation in the position and intensity of precipitation centers. Also, it has higher capability of imitating the trend of winter temperature. Meanwhile, it is poor of its performance in simulating the extreme local precipitation centers, and, there appear some dummy rainfall centers in precipitation′s simulation for large areas.
