The 1965 Apra-AEC Joint Lightning Study at Los Alamos. Volume I. The Lightning Spectrum. Charge Transfer in Lightning. Efficiency of Conversion of Electrical Energy into Visible Radiation

摘要

The visible energy radiated (3900 to 6900 A) per unit of length of lightning channel was calculated using time- and wavelength-integrated spectrographic data of the 1965 lightning study. An estimated rain-transmission correction was used. The total energy deposition was calculated, assuming a dipole model of a lightning stroke and using measured values of charge transferred and channel length. The efficiency for conversion of electrical energy to visible radiation is found to be 0.007 plus or minus 36%. (Author)
