 note = {To see the mechanism of radiation from a lightning flash, we observed atmospherics in the frequency range of 0.1 to 500 Mc/s under thunderstorm conditions. Within the distance of 30 km from the origins, the intensity of atmospherics from a discharge is of the order of 0.1 v/m at 100 kc/ s in case of band width 10 kc/s. With the increase of receiving frequency, the intensity decreases roughly in inverse proportion to the frequency, but in the range higher than about 3 Mc/s it seems to decrease more rapidly and show comparatively larger fluctuations than in the lower range. The radiation from a discharge is usually composed of many intermittent pulses individually associated with electrostatic pulses, though it sometimes includes some long radiations such as continuing over 0.1 s especially in the close vicinity of origins. The first leader of a ground discharge is one of the most powerful radiation origins in any frequency, but the return process does not always show a large intensity in the range higher than 10 Mc/s.},
