摘　　要：文章旨在通过对相近的两个大气电场仪的大气电场强度进行分析,找出不同观测环境对观测值的影响。通过对距离相近的内蒙古气象局站和内蒙古医科大学附属医院站2018年8—9月以及2019年7—9月的大气电场数据进行波形对比、数据分析,得到不同天气条件下两站数据间呈倍数的相关性,晴天、阴天、降雨、雷暴4种天气的平均线性倍数分别为5.45、5.716、6.14、5.1。仅考虑距离因素时,由于内蒙古气象局站的大气电场仪距离附近最高建筑物较远,对该站大气电场的影响可以忽略。只考虑高度因素时,两站的相关系数为5.544。相比不同的天气条件,高度对两站数据线性倍数影响较大。为修订两站大气电场仪观测结果,调整预警阈值,提高多站大气电场仪监测预警的准确性提供理论依据。This paper aims to find out the influence of different observation environment on the observed value by analyzing atmospheric electric field intensity of two close atmospheric electric field instruments. Through the comparative of waveform and data analysis of atmospheric electric field data from August to September 2018 and July to September 2019 of Inner Mongolia Meteorological Bureau station and Affiliated Hospital of Inner Mongolia Medical University station, we obtain the multiple correlation between the data of the two stations under different weather conditions. The average linear multiples of sunny, cloudy,rainy and thunderstorm were 5.45, 5.716, 6.14 and 5.1 respectively. When only the distance factor is considered, the influence of the atmospheric electric field can be ignored because the distance between the atmospheric electric field instrument of Inner Mongolia Meteorological Bureau station and the highest building nearby is far. The correlation coefficient is 5.544 when height is considered only. Compared with different weather conditions, height has a greater influence on the linear multiples of the two stations.It provides a theoretical basis for revising the observation results of the atmospheric electric field instrument at two stations, adjusting the warning threshold, and improving the accuracy of the monitoring and early warning of the atmospheric electric field instrument at multiple stations.
