air discharge

air discharge

[′er ′dis‚chärj]
(geophysics)
A form of lightning discharge, intermediate in character between a cloud discharge and a cloud-to-ground discharge, in which the multibranching lightning channel descending from a cloud base does not reach the ground, but succeeds only in neutralizing the space charge distributed in the subcloud layer.
A type of diffuse electrical discharge occasionally reported as occurring in the region above an active thunderstorm.
