两个雷电预警系统的应用和对比

四川省防雷中心自主研发了多因子融合雷电短临预警系统,并投入业务试运行.协助中国气象科学院研制开发了CAMS_LNWS雷电临近预警系统,并进行本地化处理和业务试用.对两个系统进行了简要介绍,并就应用情况进行了比较分析.结果表明：两个系统均具有较强的雷电预警能力,对19次雷电天气过程预警的TS评分,平均超过0.75.在实际应用中发现：CAMS_LNWS系统对未来新生雷电活动有更强的预警能力,而多因子融合短临预警系统则对已经出现雷电的移动路径和未来发展趋势有更好的预警效果,两者之间的结合应用为四川省雷电短临预警提供了技术支撑.

Applications and Comparative Analysis of Two Lightning Forecasting Systems in Sichuan

The Sichuan Lightning Protection Center developed the multi-factor lightning nowcasting system, which has been put into operational use. Cooperated with the Chinese Academy of Meteorological Sciences, the CAMS_LNWS lightning nowcasting system was manufactured and localized in Sichuan. A brief introduction is made to the two systems and the trial use in lightning forecasting. The results by forecasting 19 lightning activities show that they both have strong lightning warning capability, and their TS score are greater than 0.75. The CAMS_LNWS system has well warning capability for new-appearing lightning activities, and the multi-factor lightning nowcasting system is better in the prediction of moving path and development. Combination of two systems can provide well technical support for nowcasting service in Sichuan. ightning ightning
