| 摘 要： | 2011年7月24日—8月4日呼伦贝尔市出现了一次鄂霍次克海阻高影响下的降水天气过程,此次降水过程历时之久为历史罕见。文章通过分析降水过程天气尺度大环流背景影响下的中小尺度天气系统的活动,结合水汽通量散度、垂直速度、涡度等物理量场的分布,发现受鄂霍次克海阻塞高压的阻挡,高空槽稳定摆动且发展为低涡,为暴雨的反复出现提供了极有利的天气尺度环流条件。

| Abstract: | A precipitation weather process in Hulunbeir influenced by Okhotsk blocking high from July 24, to August 4 in 2011, the long duration time of which is rarely seen before. This article analyzed the medium-small scale weather system activity influenced by precipitation process weather scale in atmospheric circulation, combined with the distribution of divergence of moisture flux, vertical velocity and vorticity and other physical field, it was found that upper trough steadily swaying become low vortex influenced by Okhotsk blocking high, which provide rainstorm recurring with beneficial weather scale circulation conditions. |
