ELECTROMAGNETIC RADIATION AND PHYSICAL STRUCTURE OF LIGHTNING DISCHARGES,
Abstract
A theoretical analysis was carried out based on oscillographically obtained magnetic field variations emitted in the vicinity from vertical lightning strokes. The mechanism and the physical properties of lightning discharges as well as the distributions and the time variation of the lightning currents were treated. Methods of calculating the current variations by the use of the emitted magnetic field variations were discussed. Calculations of the lightning current by the aid of the theoretical method presented in this paper resulted for some individual cases in differences in comparison with values obtained by the aid of an approximative method conformable to the law of Biot and Savart. Notwithstanding, a comparative statistical analysis based on a more extended amount of data did not give any appreciable differences as to the results when both methods of calculation were applied.
