摘　　要：考虑大气电场仪安装的位置周围有建筑物存在,而建筑物对大气电场具有一定的畸变效应,采用有限差分方法对建筑物大气电场的畸变效应进行研究。通过对建筑物的高度、宽度、电场仪与建筑物之间的距离以及安装在建筑物群之间时,建筑物对电场仪的大气电场畸变效应的数值模拟,并求出畸变系数,再用于对大气电场仪的实际测量值进行修订。本文的研究结论,能够有效地对大气电场仪的修订以及对雷暴监测预警工作的开展提供一些思路。Consider position around the building of the atmospheric electric field instrument installation, and the building of atmospheric electric field has certain distortion effect, this paper is studying building the distortion effect of atmospheric electric field with using the finite difference method. By using the parameter such as the height, width of buildings, electric field instrument, the distance between buildings and installed in the building groups, the numerical simulation of atmospheric electric field distortion effect is carried out, and the distortion coefficient is obtained, which can be used in actual measurement value of atmospheric electric field instrument for revision. Institute of some of the conclusions of this article, can effectively the revision of atmospheric electric field instrument and provide scientific guidance to thunderstorms monitoring and early warning work.
