| 摘 要： | 为了提高四川省防雷减灾工作效率,推动雷电服务数字化、网络化、集约化、规范化、标准化,实现快速、准确、高效的雷电短时临近预警,四川省防雷中心协助中国气象科学研究院,共同研制开发了“四川省雷电短时临近预警系统”.目前四川省防雷中心已经结合本地的实际情况开展雷电临近预警业务试运行.同时在成都、凉山、眉山、绵阳、乐山等市州气象台进行区域化雷电监测预警预报推广应用,初步实现雷电监测预警预报业务和服务,并在2010 ～2011年几个重大天气过程中成功进行了雷电预警预报,同时对当地气象台站进行强天气过程预测预报提供了辅助手段,得到了有关职能部门及当地各级政府的充分肯定.

| Abstract: | To meet the increasing demand of lightning nowcasting and warning services with the rapid development of modem society, Sichuan Lightning Protection Center developed the Lightning Nowcasting and Warning system, which can obtain the lightning observation data on real time, and combined with radar, satellite and other observation data and numerical model production, to decomposition the radar image of the lightning area. And in order to trace the temporal and spatial variation of lightning, describe them by exponential trend, and build the forecast equation and model of influence time, strength and mov- ing direction of lightning, provide 0 - 1 hour lightning activity potential prediction product and lightning nowcasting and warn- ing products, the area identification, tracking and extrapolating algorithm, the ingredients - based methodology and the deci- sion tree algorithm were implemented in the system. At present, the local construct on province level has been completed, and the operational experiments of lightning nowcasting warning are also developed by the Sichuan Lightning Protection Center combination with the actual local situations. |
