中文摘要: 介绍了中国气象科学研究院研发的雷电临近预警系统(CAMS LNWS)在北京地区开展的业 务运行试验。通过运行测试以及预警结果与闪电监测结果的对比评估,表明:CAMS LNWS能够稳定运行,定时读取多种探测资料、自动生成并循环显示雷电发生概率、雷电活 动区域移动趋势和重点区域雷电危险度等级三种雷电临近预警产品;CAMS LNWS的雷电发 生概率预警产品具有较高的命中率,能够较好地对0~30min内可能发生闪电的区域进行有效 预警;随着预警时间的延长,CAMS LNWS的预警效果会有所降低。

Abstract:The operational experiment result of Lightning Nowcasting and Warning System (wh ich is developed by Chinese Academy of Meteorological Sciences, CAMS_LNWS) in Be ijing area is reported. The comparison and evaluation between the lightning nowc asting products and lightning monitoring data show that CAMS_LNWS can work stabl y, obtain many observation data regularly, automatically generate and circularly display three types of lightning nowcasting and warning products, namely the li ghtning occurrence probability, the moving trend of lightning activity region an d the lightning risk grade of key region. The lightning occurrence probability products of CAMS_LNWS have a relatively high Probability of Detectio n (POD), and it can effectively nowcast and warn the regions that may occur ligh tning flashes within 0—30 min. However, with the extension of the nowcasting an d warning lead time, the effect of CAMS_LNWS products will deteriorate.
