General Circulation Model
A Parameterization of Cumulus Convection
with Multiple Cloud Base Levels
In the Colorado State University General Circulation Model (CSU GCM), a
generalized Arakawa-Schubert cumulus parameterization with multiple cloud base
levels is used. The parameterization is based on the prognostic CKE closure and
the linear mass flux profile. The cloud base mass flux distribution and
comparisons of simulated precipitation patterns and mean meridional circulation
patterns are shown in following figures. In the figures, MCB-run and C-run mean
multiple cloud base simulation and control simulation, respectively.
Cloud base mass flux distribution for various cloud types.
