2018年7月11日满洲里暴雨成因分析

2018 年7 月11 日，满洲里地区出现暴雨天气过程，本文对该次暴雨的产生的环流背景、 水汽条件、动力条件、不稳定能量等方面进行分析。结果表明高空天气系统的调整为本次暴雨 产生提供有利的环流背景，高低空急流的耦合作用为本次暴雨提供有利的动力条件，同时低空 急流带来渤海附近的水汽为本次暴雨的持续和短时强降水的产生提供可能，不稳定能量的贮存 与释放加剧了暴雨的产生。最后本文得出此次暴雨产生的机理模型，对本次暴雨进行较为明了 的说明。

Analysis on the cause of heavy rain in manzhouli on July 11, 2018

On July 11, 2018, there was a rainstorm weather process in manzhouli region. The paper ana? lyzed the circulation background, water vapor condition, dynamic condition, unstable energy and other aspects of the rainstorm. Results show that high altitude weather system is adjusted for the heavy rain provide favorable circulation background, height of air jet coupling provide favorable dynamic condi? tions for the heavy rain, and low level jet near bohai sea water vapor for the continuous and short supply of the heavy rain of heavy rain in May, the unstable energy storage and release contributed to the heavy rain. Finally, the paper obtains the mechanism model of the rainstorm and explains the rainstorm.
