大气电场仪辅助观测机场区域雷暴的方法探析

Discussion on The Method of Observing Thunderstorm in Airport Area with the Aid of Atmospheric Electric Field Instrument

为进一步提升民航气象观测服务质量、保障民航飞行安全,该文利用厦门高崎机场大气电场仪数据,配合雷达回波图对雷暴天气过程进行分析,发现大气电场强度的变化和雷暴的产生、发展以及移动有着较好的对应关系——当大气电场强度变化曲线由稳定逐渐变化为快速波动,最大值不断增大且不断波动时,说明强对流天气即将发生。雷暴天气现象发生时,大气电场强度首次增大达到极大值的时间,与观测员第一次闻雷时间有较好的关联性,对观测员观测雷暴有着较好的预警作用。

In order to further improve civil aviation meteorological observation services and ensure the safety of civil aviation flight, this article uses the date of atmospheric electric field meter at Xiamen Gaoqi International Airport as well as radar echo images to analyze the process of thunderstorm weather. The study finds that the changes in the atmospheric electric field intensity is well correlated to the occurrence, development, and movement of thunderstorms. When the variation curve of the atmospheric electric field intensity gradually changes from stable to rapid fluctuation, and the maximum value keeps increasing and fluctuating, it indicates that strong convective weather is about to occur. When a thunderstorm weather phenomenon occurs, the time when the intensity of the atmospheric electric field first increases to a maximum value has a good correlation with the time when the observer first hears the thunderstorm, and it has a good early warning effect on thunderstorm observation.
