高原地区雷暴过程地面电场变化特征分析

Analysis of Characteristics of Electric Field Change during Thunderstorm in Plateau

高原地区是我国雷暴天气多发区之一。通过对大气电场仪所测得雷电过程地面电场变化特征的分析有助于了解这一地区的雷暴特征，对认识该地区雷暴过程特征有一定的参考价值。对雷暴过程初期的地面电场波形变化的曲线拟合，总结出了共同的特征，为地面电场资料在雷电预警预报中的应用提供了参考价值。对雷暴过程地面电场资料的特征分析以及预报方面的研究都是很有现实意义的。

Plateau region is one of the thunderstorm-prone areas. It will help to understand the characteristics of the thunderstorms through the atmospheric electric field instrument measured changes in surface electric and analysis on the characteristics of the thunderstorms in this region. By the curve fitting of the surface elec, tric field during early process of thunderstorms changes and summed up a common feature, it would provided the reference in the application of the early lightning of warning and forecast. It will be valuable in analysis characteristics of ground electrical filed data during the process of thunder and lightning.
