| 摘 要： | 利用常规气象观测资料以及卫星和多普勒雷达监测资料，对2010年6月2日晋东南局地强降雹的天气过程进行分析。结果表明：此次降雹过程在500hPa高空环流形势场上呈典型的偏北气流型，低层辐合、高层辐散；蒙古脊前、冷涡后部偏北气流促使冷空气动力下传是这次局地强对流天气主要的动力触发机制；雷达回波演变显示位于低涡后部的强回波分布分散，呈现“爆米花”状；卫星云图上云顶亮温的变化与对流云团的发展有着很好的对应关系，孤立云团的合并使能量集中和加强，有利于冰雹的产生。

| Abstract: | The strong hail which happened in southeastern of Shanxi based on the observation, satellite and Doppler data. The result showed that low level convergence and upper-level divergence in upper air circulation province in June 2, 2010 was analyzed the hail was the typical north air stream, in 500hpa and the strong echo scattered and was like the ＂popcorn＂ and there was a good corresponding relation between cloud top brightness temperature from satellite image and the developing of convective cloud cluster . |
