摘要
选取湖南省长沙站的多普勒雷达资料,根据闪电定位仪数据对发生闪电和未发生闪电的雷暴单体的雷达回波资料进行对比分析验证,给出雷达回波顶高和VIL的雷电预警指标,并结合雷暴单体的速度场信息,提前0-30 min做出雷电预警,对该地区的雷电预警提供一定的技术支持。
Based on the Doppler radar data from Changsha station of Hunan province, the comparative analysis and checking analysis have been carried out; according to the data collected by lightning locator, about the radar echo data concerning the lightning storm cell and unlightning storm cell, the paper presents the lightning warning indication about radar echo top and VIL; in combination with the speed information, it can make lightning warning ahead time from 0 to 30 minutes. This result supplies certain technical support to the lightning warning in this region.
