中文摘要: 利用1996—2005年近10年的MICAPS和NCEP2.5°×2.5°再分析资料,对影响华南地区的西 南低涡以及致洪低涡活动进行系统性的统计研究,给出影响低涡活动的频率、集中生成地、 移动路径、生成和移动过程中的强度、影响时的生命史、平均环流场、降雨特点等气候特征 ,建立影响低涡致洪暴雨天气系统配置及其模式图,为华南地区低涡及其致洪暴雨预报提供 依据。

Abstract:MICAPS data and NCEP 2.5°×2.5°reanalysis data during the period of 199 6—2005 are used to make statistical research on the activity of southwest vorte x and flood producing vortex influencing South China. The climatic features such as frequency of vortex activity, genesis, movement track, and intensity during t he genesis and moving process, and its lifetime, average circulation field, and precipitation features are investigated. And the allocation of influencing flood producing synoptic system and its model graph are offered to provide basis for forecasting vortex and flood producing heavy rainfall in South China.
