摘要
2017年8月3-4日受高空槽和南部低压系统共同影响,自南至北绥化市出现一次暴雨、大暴雨天气过程。本文利用MICAP3.2资料、常规观测资料、自动站资料,卫星、雷达资料对暴雨产生进行分析,这次暴雨产生的主要原因是高空槽与南部的低压系统共同影响,低空西南急流为暴雨带来了充足的水汽和不稳定能量,充分的动力条件和大量的水汽是导致本次暴雨产生的主要原因。
Due to the combined effect of the high-altitude trough and the southern low-pressure system, a heavy rainstorm weather occurred in Suihua City from south to north during3-4,August ,2017. MICAP3.2 data, conven- tional observation data, automatic station data, satellite and radar data are used to analyze the occurrence of heavy rain. The main reason for this torrential rain was the joint impact of the high altitude trough and the low pressure system in the south. The southwest jets at the low altitude brought enough water vapor and unstable en- ergy for the heavy rain. The full power conditions and large amounts of water vapor were the main causes of the heavy rain.
