摘要
为了提高宁夏对暴雨天气的预报能力,利用常规气象资料及卫星、雷达等先进探测工具,应用天气学和诊断学方法,从环流形势及影响系统、动力条件和水汽条件等方面对2004年8月19日固原市区域性暴雨过程进行分析,剖析该次暴雨形成的物理机制;应用MM5中尺度模式对暴雨天气进行模拟,模拟结果表明,MM5对强降水过程有较好的预报能力.
In order to gain many information of rainstorm, based on normal meteorogical regulations and digital satellite and Doppler radar data, using the principle of meteorology and diagnostics, the cause of formation of a regional rainstorm in Ningxia on August 19,2004 and the physical mechanism were analysed. At the sametime, weather of rainstorm was simulated by MM5, The simulated result indicated that MM5 is available for forecasting strong rainfall.
