中文摘要: 通过对1993年8月4-5日鲁南特大暴雨的环流背景、环境场特征及中尺度系统的诊断分析,指出:在副热带高压加强西伸、高原槽携西南涡东移的有利环流背景下,低空偏南急流将高能暖湿空气输送到低涡辐合中心前部的东西向静止锋上被强迫抬升,引起中尺度对流复合体的发生、发展和再生,是造成鲁南特大暴雨的基本原因。

Abstract:Dignosis shows that the basic contributing factors caused the exceedingly heavy rain during August 4-5, 1993 in southern Shandong Province are as the following. Under the suitable circulation background as subtropical high intensified and spreaded westward,and the plateau trough moved eastwards with the southwest vortex,warm and wet air with southerly jet at the low layer were transported and reached over the stationary front (from west to east) in the front of the convergence core of the law vortex,and forced lifted, then, MCC (Meso-scale Convective Complex) generated, devdoped, and regenerated.
