【摘要】 揭示了“91·7”鲁西大暴雨的主要成因,对卫星云图、雷达回波和地面中尺度系统进行了分析研究,提出本次大暴雨是中纬度西风槽与低纬度台风云系相互作用的结果;指出地面中尺度高能舌之前,有中尺度辐合线(辐合中心)产生,易触发龙卷、飑线等强对流天气。更多还原

【Abstract】 Based on the study of the satellite image, the radar echo and the surface meso-scale systems, the article mainly focuses on explaining how the "91. 7" Heavy Rain was developed and concludes that the rain-storm was a consequence of the interaction between the middle latitude westerly trough and the low latitude typhoon cloud-cluster;it also points out that if surface meso-scale convergence line (convergence center) appears in front of the surface meso-scale high energy tongue, then severe convective weather such as tornado,squall line,etc. would easily emerge.更多还原
