Natural Lightning Parameters and their Simulation in Laboratory Tests

Abstract

The paper summarizes our knowledge of natural lightning. The derivation of flash incidence from thunderstorm day statistics is first discussed. Information on lightning parameters is then reviewed; these parameters include peak current, rate of current rise, intermediate current, continuing current, action integral, and several others. Parameters of importance in aviation hazards are given particular attention. The characteristics of positive flashes are examined, and the question of the representativeness of discharges to tall structures is considered. The electromagnetic fields radiated by close flashes are described. Finally, the realism of lightning models, specifications, and simulation tests, as they relate to natural lightning is critically discussed.
