| 摘 要： | 利用天气实况图、自动站资料、多普勒天气雷达及风廓线雷达分析2011年4月17日影响广州市南沙区的一次强对流天气过程的成因。结果表明:环流系统和中尺度影响系统配合较好,多普勒雷达观测到弓形回波和超级单体风暴是这次强对流天气的主要影响系统,而风廓线雷达测得的温度及风向风速资料可以监测边界层能量堆积情况及水平风的垂直切变等现象,值得预报员关注,以提前做好预报预警工作。

| Abstract: | Using Micaps,surface observation datas,doppler radar and wind profile radar datas,the cause of severe convective weather process occurred on April 17 th,2011 in Nansha district of Guangzhou City was analyzed.The result showed that:the circulation and mesoscale affecting systems matched well,observed echo by doppler radar and the supercell storm were the main influncing system of this severe convective weather process,the temperature and wind speed data provided by wind profile radar data could monitor the boundary layer energy accumulation and vertical shear of horizontal wind phenomenon.It deserves weatherman′s concern,in order to do early warning and fore-casting. |
