Cumulonimbus vertical velocity events in GATE. Part II: synthesis and model core structure.

Abstract

By our definition a convective updraft must have a positive vertical velocity for 0.5km, and exceed 0.5 m s-1 for 1 s; a convective updraft core must exceed 1 m s-1 for 0.5km. Downdrafts and downdraft cores are defined analogously. Here the properties of the drafts and cores are compared to results of previous work. In addition, the implications of the results in Part I are discussed.-from Authors Nat. Center for Atmos. Res., Boulder, CO 80307, U.S.A.
