摘要
本文采用了schmid ,house ,schiesser与fovell左移雹暴和右移雹暴的定义 ,对河套区左移强雹暴的天气形势和物理量场进行分析 ,得出左移雹暴和右移雹暴产生的有利天气尺度及中尺度主要特征。论述了左移和右移雹暴传播活动和雷达回波特征。
Based on the definition of left-moved and right-moved hailstorm by Schmid, Houze, Schiesser and Fovell,by analyzing the weather conditions and physical parameters of the left-moved heavy hailstorm in north of Shaanxi,we get the main characteristics of the favorable weather-scale and meso-scale,and study the characteristics of the hailstorm movements and the radar echo of the left-moved and right-moved hailstorm .
