摘要
本文利用不同高度大气电场实测数据，对近地面层大气电场随高度的变化规律进行了研究。通过数据对比及最小二乘法拟合分析，得出以下结论：近地面层大气电场强度随高度呈指数递增；同一时段不同高度之间的大气电场变化趋势是一致的，且这一特征不受天气条件影响。
We carry out the test and analyze the observation results in the atmospheric detection base of Xiamen straits. In order to understand the vertical variation characteristics of atmospheric electric field in the coastal areas of Xiamen, the probe datum of atmospheric electric field are analyzed. The relationship between X/amen coastal atmospheric electric field of sunny day varying with height and atmospheric electric field in different heights are given. The results show that the atmospheric electric field intensity within the surface layer of 30m in the coast areas of Xiamen increases exponentially with height. The variation trends of atmospheric electric field are consistent among different heights during the same period, and this feature is not affected by weather conditions. The change of atmospheric electric field is a good indicator for different weather.
