Numerical simulation method for atmospheric electric field distortion effect of buildings under different parameters

Abstract

The invention discloses a numerical simulation method for an atmospheric electric field distortion effect of buildings under different parameters. The numerical simulation method comprises the following steps of (1) solving an atmospheric electric field distortion coefficient of the buildings through a finite difference method, wherein the finite difference method is as follows specifically: performing discretization on a researched spatial simulation region, using a finite difference equation to replace a differential equation, performing uniform division after grid discretization for data processing, and solving electric potential values of respective grid points in a discretized space range; and (2) solving the finite difference equation, performing sub-division on grids in the spatial simulation region, solving electromagnetic problems in the spatial simulation region, selecting an iteration factor, and then solving the atmospheric electric field distortion coefficient of the buildings. By performing numerical simulation on the atmospheric electric field distortion effect of the buildings, the actual measurement value of an atmospheric electric field instrument can be revised, so that the accuracy of thunder and lightning monitoring and early warning can be improved.

Description

technical field [0001] The invention relates to a numerical simulation method for the distortion effect of different parameters of buildings on the atmospheric electric field, and belongs to the technical field of lightning monitoring and early warning. Background technique [0002] Thunderstorm refers to the violent discharge phenomenon of thunder and lightning that occurs in cumulonimbus clouds. As a local strong convective weather phenomenon, it is often associated with disastrous weather such as heavy rain, strong wind, hail, and tornado. The safety of people's lives and property poses a serious threat, so thunderstorm monitoring and early warning work is particularly important. The atmospheric electric field instrument is an important part of the thunderstorm monitoring and early warning system. Since there are buildings around the location where the atmospheric electric field instrument is installed, the building has a certain distortion effect on the atmospheric elect...
