Distribution of Mesoscale Convective Complex Rainfall in the United States.

Utilizes results from each of the mesoscale convective complex (MCC) summaries compiled between 1978 and 1999 for the U.S. in order to develop a more complete climatology, or description of long-term means and interannual variation, of these storms. Indication that during the warm season, significant portions of the Great Plains receive, on average, between 8 percent and 18 percent of their total precipitation from MCC rainfall.
