Abstract
Thunderstorm electrical activity in terms of surface-observed lightning-stroke rate is related to that radar-reflectivity maxima above the 0C level and to vertical profiles of radar reflectivity. This, and the fact it is also related to the incidence of hail at the surface, lends support to a previously stated theory of charge generation and separation by Workman and Reynolds. Observer data show an order of events at the surface which indicates a thunderstorm structure coinciding with previous models.
