摘要
飑线是一种线状的中尺度对流系统,发生时破坏力大,可以造成严重的经济损失和人员伤亡。在我国,几乎每年都会出现由飑线引起的巨大损失。近年来,国内外对飑线的研究不断发展,无论是从大尺度环流背景、形成机制、组织形式、内部结构还是维持机制都有了较为深入的研究。深入研究飑线的形成过程,对于预报和灾害预警、防护,都具有很重要的意义。
Squall line is defined as a line-shape mesoscale convective system,which has destructive power and can cause huge economic losses and casualties. In China, there are great losses caused by squall lines every year. In recent years, there are much domestic and abroad progresses on the research of squall line in the respects of its circulation background,organizational mode, inner structure and maintaining mechanism. Further research on the formation of squall line plays an important role in the prediction, early warning and protection of disasters. In this paper, the summary of above conclusions are presented to provide a better understanding of squall line.
