| 摘 要： | 本文对2013年8月7日发生在黑龙江省中、东部地区的一次分散性暴雨天气过程进行了分析,通过卫星云图、多普勒雷达资料以及动热力条件等情况,详细讨论分析了此次暴雨天气产生的原因。结果表明:本次暴雨过程是中小尺度系统产生的对流性降水,强的热力不稳定层结是中小尺度系统发生发展的背景条件;暴雨以地面暖锋为触发机制,暖锋在黑龙江省南部停留时间长,是本次对流性降水过程持续时间较长的主要原因。

| Abstract: | Analyze the disperse rainstorm weather process in the central and eastern regions of Heilongjiang Province on August 7th, 2013 .Discuss the cause of the rainstorm weather with the satellite cloud picture, doppler radar data and dynamic thermal conditions. The results show that this rainstorm process is a convective precipita- tion caused by the meso-and micro-scale systems; the strong thermal instability stratification serves as the back- ground condition for the meso-and micro-scale systems; In this rainstorm, the ground warm front is the trigger mechanism. The long stop of warm front in the south of Heilongjiang Province is the major reason of the long du- ration of this convective precipitation. |
