Abstract
ULTRA-RAPID photography has shown that lightning strokes consist of a ‘leader’ from cloud to earth and a return stroke in the opposite direction. From fluctuations in the luminosity of the return stroke at the ground end, D. J. Malan, Dr. B. F. J. Schonland and H. Collens infer that the return stroke is made up of several component discharges, the intensity and time separation of which in micro-seconds they have measured. The authors are now investigating the influence of these components upon the waveform of atmospherics radiated by the lightning flashes.
