We have benefited considerably from the advice and comments of Michael Baldwin, Steven Corfidi, Greg DeVoir, Paul Janish, Ann McCarthy, and Drs. Daniel Keyser, Donald MacGorman, John Molinari, James Moore, Richard Rotunno, David Rust, Terry Schuur, Charles Seman, Alan Thorpe, and Jeff Trapp. Insightful reviews of earlier versions of this manuscript were provided by George Bryan, Ronald Holle, and Drs. David Blanchard, Kerry Emanuel, Jack Kain, Robert Maddox, Jonathan Martin, John Nielsen-Gammon, Paul Roebber, David Stensrud, Robert Weisman, Earle Williams, and Qin Xu. Katherine Day (NOAA Library, Boulder, Colorado) obtained lists of references at our request, assuring a thorough bibliography to draw upon for this review. The first author thanks Dr. Charles Doswell III for his invaluable discussions/arguments on atmospheric convection and encouragement during the preparation of this manuscript. Most of this research was conducted while the first author was a National Research Council Postdoctoral Research Associate at the National Severe Storms Laboratory. This work is inspired by and dedicated to the late Dr. Bernard Vonnegut, who challenged us to scrutinize paradigms.
