Abstract

Enhanced infrared satellite imagery is used to document the occurrence of mesoscale convective complexes over the United States during 1983. Thirty large convective systems are identified that display satellite-observable characteristics which satisfy the MCC criteria described by Maddox. Details of the life cycles of these 30 systems are given and four examples are discussed in the context of large‐scale midtropospheric features. This is the third in a series of annual summaries assembled as a documentation for those interested in investigating the mesoscale convective weather systems that occur over the United States.
