分光分析を用いた大電流・雷パラメータセンシング手法の確立への基礎研究

Abstract

The authors could measure many date at the indoor discharge experiment and rocket-triggerd lightning experiment for establishment of lightning parameter sensing method. As for the indoor experiment, the result could get the sperctrum distribution photography. Also, the authors have been taking part in the trggered lightning experiments in winter, at the site Okushishiku, Ishikawa, for the purpose of observing the entire lightning current waveforms and spectroscopic photographs since 1986. As that result, the current waveforms were similarly to the typical winter positive current waveforms. The wavelenrth of strong radiance was selected by sperctroscopic photography.
