【摘要】 利用常规和多种高分辨率非常规观测资料,分析了2006年7月3日傍晚到夜里盐城市中-β尺度大暴雨过程,发现此次降水是发生在副高边缘的高能量堆积区,冷空气的侵入是强降水的主要原因,而地面辐合是强降水出现的主要触发机制,充沛的水汽输送、聚集的对流有效能量为暴雨中尺度系统发生发展提供了必要的物理机制。更多还原

【Abstract】 Based on the conventional radiosonde and surface observation as well as high resolution non-conventional data,a heavy rain event in Yancheng,Jiangsu Province on 3 July 2006 is diagnosed.It shows that the event occurred in the area of high energy accumulation at the edge of the west Pacific subtropical high.And the main reason of the heavy rainfall is the cold air invasion. Surface convergence is the primary trigger mechanism to lead the heavy rainfall.The rich moisture transmission and the concentrated convection available potential energy provided the physics mechanism for the occurring and development of mesoscale heavy rainfall system.更多还原
