柳州"4·09"致灾冰雹的超级单体风暴过程分析OA北大核心CSCDCSTPCD
Analysis of Supercell Storm Leading to Disastrous Hail in Liuzhou on 9 April 2016
利用柳州和桂林天气雷达(SB)资料和相关实况资料,对2016年4月9日夜间柳州一次强雹暴天气的环境条件和雷达回波结构演变特征进行了详细分析.结果表明:(1)雹暴发生在低层热低压发展,中层有冷温槽发展东移,高层有急流的背景下.地面干线和中尺度辐合线触发的对流云团在不稳定层结和较强的深层垂直风切变作用下发展为超级单体.(2)超级单体的低层反射率因子呈现出明显的钩状回波或倒"V"型入流缺口.反射率因子垂直剖面呈现出典型的有界弱回波区、回波悬垂和回波墙.…查看全部>>
Based on the Doppler weather radar data of Liuzhou and Guilin,and the conventional upper-air and surface observation data,this paper analyzes the environmental condition and radar echo structure of the severe hailstorm which occurred in Liuzhou on 9 April 2016.The results show that:(1)The back-ground responsible for the hailstorm includes intense heating-up of the surface which led to the develop-ment of thermal depression in the lower atmosphere,the develop…查看全部>>
