摘要
通过对2009年7月7～8日发生在宁夏北部石嘴山市的一次区域性暴雨过程进行环流形势、雷达回波及物理量场等方面的特征分析,认为西风槽、低涡切变及中尺度系统是此次暴雨的主要影响系统,指出了其产生的动力场特征及热力机制。同时,提出了区域性暴雨的预报要点。
The heavy rain on July 7-8,2009 in Shizuishan of Ningxia was synthetically analyzed in circulation trend,radar echo and physical variable field.The results showed that the mainly influencing systems of rainstorm included westerly trough,vortex,shear line and mesoscale system.It was pointed out that the characteristic of dynamic condition,thermodynamics mechanism and forecast essential of regional rainstorm.
