Lightning-warning data was taken during the 1974 thunderstorm season at Holloman AFB, N.M. using a GCA Model EL-300 Lightning-Warning Set. A computer program was then written to analyze this data in order to optimize the choice of warning criteria to be established in using the Lightning-Warning Set for tethered balloon operations at Holloman AFB. This report provides a discussion of the various criteria which were employed in the computer program in order to provide a one hour and a 5 minute warning of an impending electrical hazard. From these various criteria one was chosen which provided a minimum number of hours under false warnings and a minimum number of hazardous conditions without warnings.
