摘要
本文统计了1970~1989年20年西南低涡生成的资料,得到了西南低涡生成的月际和年际分布的其本事实。在此基础上分析了生成低涡的500hPa环流背景和九龙涡生成的地理环境,试图揭示西南涡生成的机理,最后,文章利用非热成风适应原理,对低涡生成机理进行了理论分析。
We have statistics on the formation of the Southwest China Vortex during 1970-1989 years and obtain some basic facts about its monthly and yearly changes. In this paper the circulation on 500 hPa and geographic environment about Vortex source,and endeavor to reveal the generative mechanism of the Southwest China Vortex are analysed. Here it is discussed theoretically in the non-thermal wind adjustement principle of nonadiabatic and topographic effect.
