Abstract:

The Southwest China vortex is one of the important weather systems affecting the precipitation in China. Statistical analysis was used earlier in the study of the Southwest China vortex activity. The paper reviewed the research progress of the Southwest China vortex based on the climatic statistical analysis since the late 1980s, and summarized briefly the major achievements about the properties, multi-scale time variation, activity characteristics of the Southwest China vortex and its impact on the precipitation. And on the basis it tried to analyze and summary the existing problems of the Southwest China vortex in statistical analysis, which would be necessary to think seriously and research deeply in the future.

Key words: Southwest China vortex, statistical characteristics, review, prospect

摘要：

西南涡是影响我国降水的重要天气系统之一。统计分析是较早运用于研究西南涡活动的方法。本文回顾了从20世纪80年代末期至今关于西南涡的气候统计分析结果，简要总结了关于西南涡的属性、多尺度时间变化、活动特征及其对天气影响等方面基于统计分析的主要成果，在此基础上，分析、归纳出今后需要深入分析和进一步研究的若干问题。
