Abstract: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 075 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 lightning moving path and development.Combination of two systems can provide well technical support for lightning nowcasting service in Sichuan.
