中文摘要: 1998年7月20~23日,湖北省南部发生了一次持续性特大暴雨过程,采用双向嵌套的非静力中尺度数值模式(MM5)对这次强暴雨过程进行初步模拟试验。结果表明,粗、细网格均能较好地模拟出雨带的走向和变动以及武汉地区的暴雨中心,尤其是嵌套域(细网格)模拟的降水强度比粗网格有明显改进,和实际观测结果更接近;另外,对引发这次特大暴雨的对流层低层的中尺度系统也能够很好地模拟出来。
Abstract:A sustained anomalous heavy rainfall event occurred over southern Hubei Province during 20—22 July 1998. A two-way nested nonhydrostatic mesoscale numerical model called MM5 was conducted to simulate the event. The simulative results show that the rain-band distribution with its center is basically consistent with that of the observation, especially for the results derived from the fine nested simulation that are very closely with the observations. In addition, the mesoscale system connecting with the heavy rainfall occurred in 20—22 July is simulated successfully.
