Problems solved by technology

[0003] The amplitude of the pulse current and continuous current is much smaller than that of the return current, but because its duration is much longer than that of the return, a large amount of charge is transferred from the cloud to the ground during the process, which makes the charge moment of the lightning discharge continue to increase

Abstract

The invention relates to the technical field of lightning monitoring systems, in particular to a method for calculating the quasi-electrostatic field energy of ground lightning. The method comprises the following steps: receiving an electromagnetic signal of ground lightning; transmitting the electromagnetic signal to a processor for processing to obtain a processed electromagnetic signal; calculating a pulse response function through a time domain finite difference method FDTD; performing deconvolution on the processed electromagnetic signal and the pulse response function to obtain a ground lightning current moment waveform; and performing time integration on the ground lightning current moment waveform, and obtaining the ground lightning quasi-electrostatic field energy. The detection efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of lightning monitoring systems, and in particular, to a method for calculating the quasi-electrostatic field energy of a ground flash. Background technique [0002] Cloud-to-ground lightning (referred to as ground-to-ground lightning) is a common natural lightning phenomenon that often occurs in strong convective weather. When a lightning strike occurs, the cloud layer usually releases a high-intensity pulse current to the ground. Some scholars speculate that the part of the cloud may contain a large number of forked horizontal channels. When the positive flashback front reaches the end of the channel, it will contact with these horizontal channels in the cloud, and a large number of positive charges enter the discharge channel to make The current continues to increase, forming a pulse current. [0003] The amplitude of the pulse current and continuous current is much smaller than that of the re...
