Abstract : Gridded Miami WSR-57 radar PPI data during the summer of 1968 are used to study the coverages and frequencies of radar echoes typically associated with five convective regimes in South Florida. Three sets of maps are presented showing the average coverage considering all of the data, the average coverage per echo incident, and the frequency distribution of grid squares containing echoes at 0800, 1200, 1600 and 2000 EST. The maps are discussed with respect to convective echo activity, and with regard to preferred regions for the occurrence of anomalous propagation (A.P.). Various local effects are noted and one outstanding 'hot spot' of convection is observed in the Lostman's River area along the southwest coast of Florida. These series of maps provide a basis for determining the degree of convection on a real-time basis. By definition, the degree of convection is related to specific daily rainfall data. (Author)
