Current, core channel radius, and related parameters of channel plasma in artificially triggered lightning.

Based on plasma physics methods, the relationship among the channel current (i), core channel radius ( r c c ), and other related parameters including electrical conductivity (σ), thermal conductivity ( λ e ), and thermal diffusion coefficient ( D e T ) was investigated and strong interdependence was found among these parameters. Then, these dependent relationships together with the measured electron temperature ( T e ) and electron density ( n e ), derived from spectral diagnostics, were applied to determine the measured results on the i, r c c , σ , λ e , and D e T of channel plasma in artificially triggered lightning along with their measured accuracies. Good accordance can be found with the aid of comparisons with other measurements of the artificially triggered lightning [L. Cai et al., J. Electrost. 109, 103537 (2021)]. [ABSTRACT FROM AUTHOR]
