中文摘要: 利用PSU/NCAR中尺度非静力数值预报模式MM5,对2002年7月22日08时到23日08时的一次强梅雨锋暴雨过程进行了数值模拟研究,模拟结果很好地描述了暴雨的时空分布及相伴随的中-β尺度系统的发生发展过程。进一步分析得出中-β尺度系统的发生发展条件及各生命史阶段高低层流型特征及其配置情况。

Abstract:A Mei-Yu heavy rain event in the middle reach of the Changjiang River during July 22—23, 2002 is simulated by use of PSU/NCAR mesoscale nonstatic numerical forecast model MM5. The simulation result describes successfully the spatial and temporal rainfall distribution of the event and the developing course of the concomitant meso-β-scale systems. The analysis shows the characters of the high and low level stream field in various stage of the life cycle of the meso-β-sclale system.
