Description:
Lightning location data from northeastern Colorado and central Florida for the summer months of 1983 have been studied to ascertain the diurnal development of spatial distributions of flash frequencies. The data sources are discussed, and for both investigated regions, the regional geographic and climatic characteristics, the day-to-day variability of lightning activity, the diurnal cycle over the entire region, the spatial distribution of lightning activity, the diurnal changes of spatial distribution, and the diurnal variation of lightning at individual sites are described in detail. In both regions, the time and space distributions of lightning are modulated by the topographic features and the contrasts of the terrain. Lightning activity is a relatively rare and variable phenomenon in both regions when day-to-day frequencies are considered. There thus must be meteorological parameters that determine the extent and frequency of lightning occurrence.
