A small set of in situ aircraft and ground-based radar data acquired during the 1981 and 1982 Joint Agency Turbulence Experiment is used to study the relationship of aircraft lightning strikes to storm precipitation, turbulence severity, and wind shear. The strikes were found to be strongly correlated with vertical drafts, predominantly downdrafts. Strikes were also well correlated with regions of strong turbulence. However, since most strong turbulence episodes encountered by the aircraft were not associated with lightning, use of lightning location methods to map hazardous turbulence within storms is considered unreliable. The strikes occurred in storm regions having a radar reflectivity factor between 25 and 35 dBZ (dBZ represents 10 log Z, where Z is the reflectivity factor). These regions were generally on the boundaries of the dominant storm precipitation cores. Storm wind shear was frequently high in regions near aircraft strikes.
