Abstract : In a ground evaluation of an airborne lightning locator system, lightning stroke rates per 4 minutes were compared with aircraft turbulence during thunderstorm penetrations. Data were taken on 3 thunderstorm days and summarized mostly into 15-minute periods consisting of three to four aircraft penetrations. Stroke rates varied considerably and did not show a linear relationship to aircraft turbulence. However, when average stroke rates for the 15-minute periods increased, aircraft turbulence increased and vice versa. It is concluded that the lightning locator system is a potentially useful thunderstorm turbulences warning device, but requires further ground/air testing. (Author)
