| 摘 要： | 本文根据2010年9月17日成都地区一次强雷暴过程中大气电场仪和闪电定位资料,分析雷暴起始、发展、消亡阶段地面电场演变特征,通过对比地闪监测网资料发现地面电场仪能够准确反映闪电活动规律。将地面电场仪与闪电定位资料相结合,可大大提高雷电预警的准确性,同时实现面向重点区域的雷电短临预警,该预警模式具有时效性高、准确率高等特点,同时也能够有效弥补现有雷电预警方法的不足。同时为四川省强对流天气系统的演变和分类检测和临近预报提供参考。

| Abstract: | This paper is based on the atmospheric electric field meter and lightning location date of a strong thunderstorm in chengdu area on September 17, 2010. The evolution characteristics of ground electric field in the initiation, development and extinction of thunderstorms are analyzed. By comparing the monitoring network data, the ground electric field instrument can accurately reflect the law of lightning activity. Combining the ground electric field instrument with the lightning location data can greatly improve the accuracy of lightning warning, In the meantime, the lightning alert in the focus area is realized. The warning model has the characteristics of high time efficiency and high accuracy, and can effectively make up the deficiency of the existing lightning warning method. At the same time, it provides a reference for the evolution and classification detection of the strong convective weather system in Sichuan province. |
