电场资料在贵阳机场雷暴天气中的应用

Application of electric field data in thunderstorm weather of Guiyang airport

  • 摘要: 利用DNDY型大气电场仪对贵阳机场2011年1月2012年6月的雷暴过程进行探测研究,分析雷暴过程中雷暴云的电荷结构和电场曲线的特征,并详细分析贵阳机场2012年5月12日雷暴天气过程的电场变化.结果表明:大气电场资料可在一定范围内对雷暴进行短时预报和预警.贵阳机场雷暴过程产生的地面电场曲线有突升型、突降型和波动型,当地面电场曲线出现高频快变抖动且电场强度达5~10 kV/m时可作为贵阳机场可能出现雷暴的预报指标.地面电场曲线快变尖峰的出现表示发生云地闪,也表明雷电已发生.

     

    Abstract: The DNDY atmospheric electric field instrument is used to research the thunderstorm of Guiyang airport betwwen January 2011 to June 2012,and analyse the feature of charge structure and electric field curve of thunderstorm cloud,and amply analyse the electric field variation of thunderstorm of Guiyang airport on May 12 th,2012.The result shows that,the atmosphere electric filed data can forecast and warm the thunderstorm in certain range.When the thunderstorm occurred in Guiyang airport,the electric filed curve is divided into the jumping type、Droping type and undulation type.When the electric field curve has a high frequency fast jitter and electric strength reachs to 510 kV/m,it may be the forecast index of thunderstorm of Guiyang airport.The fast spike of the electric field curve shows that the light between cloud to ground occurs,and the thunderstorm already occurs too.
