Transport Coefficients of Lightning Discharge Plasma on Plateau Area in China

Abstract

According to the four spectra of a cloud-to-ground lightning discharge, channels have been captured by a slitless spectrograph in Qinghai and Tibet plateau, the electrical conductivities are calculated, and, for the first time, the electron thermal conductivities and the electron thermal diffusivities are calculated by applying the transport theory of air plasma to the lightning channels. The results are compared with existing values, and in general, they are in satisfactory agreement. These transport characteristic parameters have added important value for further research on the transport characteristic of the current and energy of the lightning discharge channel.
