摘　　要：利用2000—2007年8年的逐日08时和20时的700hPa高空资料，对西南低涡进行普查分析，获得了2000～2007年期间西南低涡活动的一些统计事实：揭示了西南低涡年、季、月、日变化特征；得到了西南低涡源地分布的主要区域；获得了移动类西南低涡东移发展的主要路径及其统计特征，从而加深了对西南低涡的认识，有助于深入研究西南低涡。Using the observed data to analyze Southwest Vortex about 00 UTC time and 12UTC time from 2000 to 2007 year. We obtained some statistical facts . The first, it revealed different variation characters of South Vortex on annul --time scale ,monthly--time scale and daily --time scale; the second , it obtained emergent regions of Southwest Vortex; the third, it obtained main moving pathways of Southwest Vortex and its the statistical characters of pathway. To some extent, the facts make us know Southwest Vortex deeply and it was very useful to further study Southwest Vortex.
