Mesoscale Convective Complexes over the United States during 1982

Abstract

An important class of convective weather system, the mesoscale convective complex (MCC), presents many challenges and problems to both the research and operational communities. In addition, thew very large and long-lived thunderstorm systems have a significant social and economic impact resulting from associated severe weather phenomena and widespread beneficial rain. Enhanced infrared satellite images were surveyed to document MCCs which occurred over the United States during 1982. Thirty-seven convective mesosystems were identified that displayed satellite-observable characteristics which satisfied the MCC criteria described by Maddox. Details of the life cycles of the 37 cases are given and several specific cases are discussed. Current and proposed future research will focus on what are perceived to be key questions surrounding these important weather systems. This annual summary is offered as a starting point for scientists interested in pursuing studies of mesoscale convective weather systems.
