It is speculated that an NBE is instigated by the extensive atmospheric shower of an energetic cosmic ray. NBEs cause significant relaxation of the charge separation within the electrified cloud in a short time, on the order of 10 ms. The current flow causes radiation of a distinctive “bipolar ” low-frequency/very-low-frequency signal that can be recorded at locations on Earth up to thousands of km from the source. NBEs are preceded/accompanied by the most powerful very-high-frequency radio emissions seen in any kind of lightning. These intense pulsed radio emissions have been routinely detected with satellite-borne radio receivers in space. Owing to their easy detection and recognition, NBEs might be a useful remote-sensing proxy for space-based global, near-real-time remote sensing. However, in order for that potential to be realized, NBEs must be shown to be associated, as is ordinary lightning, with severe tropospheric convection
