Radar identification of urban-enhanced thunderstorm activity for Atlanta, Georgia, USA

摘要

The distribution of warm season (June through August) thunderstorm activity surrounding Atlanta, Georgia from 1997-2006 was identified from composite reflectivity data obtained from the network of National Weather Service radars (WSR-88D). Maxima of medium- to high-reflectivity episodes were identified to the north of and within downtown Atlanta and immediately east of the primary urban expansion of the central business district. Additional enhanced, high-reflectivity areas are found south of downtown Atlanta. These regions are also correlated with high-density urban expansion south of the Atlanta CBD.
