Track figures for previously documented 1978-1982 Mesoscale Convective Complexes (MCCs), as well as smaller cloud clusters and convective lines that occurred during 1979-1983, are presented. Other climatological attributes, including diurnal characteristics and average durations, are extracted from a tabular documentation of more than 500 meso-systems. This satellite-data-based climatology of convective weather systems may be used, in conjunction with climatologies of severe thunderstorms, as a research resource to help to improve the authors understanding of central United States convective weather. 收起
