长江三角洲区域性暴雨的统计诊断分析

Statistically Diagnostic Analysis on Regional Hard Rain in the Delta of the Yangtze River

  • 摘要: 利用1954年~1983年5月~8月气象资料,统计了影响长江三角洲地区的区域性暴雨类型。分析了1962年14号强台风的路径、暴雨落区以及产生暴雨的气象条件。诊断结果表明,有利大气环流形势、台风倒槽辐合线、低空东南急流、上升运动和强大的水汽通量与通量辐合是产生"6214"台风大暴雨的重要条件。

     

    Abstract: In this paper,synoptically and statistically classfied were types of regional hard rain influencing upon the delta of the Yangtze river.It was paied more attention to study the typhoon track,the coverage of hard rain and meteorological conditions causing hard rain of typhoon No.14 in 1962 (defined as "6214" typhoon).It was concluded that convergence line of inverted typhoon trough,south east jet in lower layer,upward motion,larger water vapour flux and stronger flux convergence are very important factors favorable to result in hard rain.
