内容記述 | A new equipment has been designed to record the time variation of luminosity radiated from the discharge whose stroke channel is concealed in a thundercloud. This equipment together with the atmospheric wavefrom recorder has been employed to the observation of lightning activity. It has been found that the initiation of individual cloud discharges is governed by the statistical time lag of a spark breakdown, which is altered by the conditions of the cloud activity. In the early stage of a storm activity, the interval of successive discharges is short, and the scale of each discharge is generally small, so the luminosity accompanied is too weak to be recorded. In the last stage, most of discharges have considerable scales and emit strong flashes in spite of the very weak activity of the thundercloud. The luminosities of flashes can be classified into two groups in view of their durations, i.e. the weak luminosity with long duration and the pulse of strong luminosity. In the former, the luminosity continues during the greater part of the period of a cloud flash that discharges electricity in 0.2-0.8 second. In the latter, the pulses with durations of 0.8-2 ms. are repeated irregularly at time intervals less than 10 ms. and continue during the period of one discharge. The atmospheric waveform corresponding to each light pulse is an electro-static pulse when it is recorded in the vicinity of the origin or a group of differential pulses with rapid changes when it is caught in a distant place. | |||||
