| Summary: | -10 C, -15 C, and -20 C temperature heights were associated A sum-nary of lightning characteristics was developed for the beginning of CG lightning activity. The observed median lag beginning of CG lightning flashes was 15.5 minutes. Other currents was found to be higher than positive peak currents during the day, the diurnal distribution of lightning flashes showed that the afternoon (2000-2200 UTC) was the high ground flash densities can be seen over land matching in Florida. Although thunderstorms can Occur at any time initiation characteristics. Radar reflectivity echoes at the lightning initiation signatures were also examined at all NASA Kennedy Space Center (KSC). From-n a 1989-1996 data National Lightning Detection Network. A distinct region of observed during the summer months for both negative and over KSC. Forty of the storms representing summer (May positive flashes. The absolute i-magnitude of negative peak radar- echoes, it was found that the 30 dBZ echo detected at representing winter were examined for their storms-n results. set, the spatial patterns, temporal patterns, and first stroke mean peak current were analyzed. Forty five the -I 5'C temperature height is the best indicator of the the topography of the KSC coastline. A maximum of values was three temperature heights and did not yield as successful through September) airmass thunderstorms and five storms thunderstorms were chosen due to their isolated development time between this lightning initiation signature and the time of maximum lightning activity.
