Abstract : Locations of cloud-ground lightning flashes were recorded during 1978 in south Florida; concurrently, radar data were digitized over a wide variety of meteorological conditions. Analyses show that a sharp difference exists between the frequency distributions of 1) radar cells (reflectivity maxima) associated with lightning flashes, which peaked at 46 dBz, and 2) cells without lightning, which peaked at 18 dBz. Similar results also apply for an area several kilometers around a flash, and indicate that only 20% of the radar data (above 30 dBz) accounted for nearly 70% of the collocated lightning. Other results specifying time relations, cell areas, and number of flashes are also described. (Author)
