Transport Coefficients of Lightning Discharge Plasma onPlateau Area in China

摘要

According to the 4 spectra of cloud-to-ground(CG) lightning discharge channel cap-tured by a Slit, lessspectrograph in Qinghai and Tibet plateaus, the electrical conduc-tivities are calculated and, for the first time, the thermal conductivities of electrons and thermal diffusivities of electrons are calculated by applying the transport theory of air plasma to the lightning channels. The results are compared with literature values, in general, a satisfactory agreement. These transport characteristic parameters have more important value for further research on the current and energy of lightning discharge channel.
