地形在降水天气系统中的作用研究回顾与展望

Review and Outlook of Landform Influences on Rainfall Weather Systems

地形对降水的影响一直是个研究热点,本文主要综述了地形效应在降水天气系统的生成和发展过程中的作用。主要内容有:地形对热带气旋的路径、结构、强度和降水的影响;地形对中尺度切变线、西南涡、低空急流的形成、降水的影响;地形对冷锋的移动、垂直运动以及锋生锋消的影响。

Landform influences on precipitation has been a hot issue,the previous studies focus on topographic dynamical and thermodynamical effects,or topographic influences on precipitation intensity and spatial distribution. And this paper reviewed and discussed topographic influences on precipitation weather systems,including landform influences on the path,structure,intensity and precipitation of tropical cyclone,landform influences on the formation of shear line,southwest vortex and low level air flows,landform influences on the path,vertical motion and frontogenesis （ frontolysis） of cold front.
