Use of Cloud Resolving Model to Address the
Climate Change Problem
Dr. Marat Khairoutdinov
Abstract:
A Colorado State University's 3-D massively parallel
cloud resolving
model (CSULEM) is presented. In addition to
conventional single-column-type
simulations, the model has been used to
model cloud organization and
interaction with the tropical large-scale
circulation using large
domains (up to 16,000 km in the west-east
direction and 9,000 km in the
south-north direction). Preliminary results
of a short climate simulation with
a 2-D cloud resolving model installed into
each grid column of an NCAR
Community Climate System Model (CCSM) are
presented. The climate
simulations using the NCAR CCSM with a new
variant of the
Arakawa-Schubert cumulus parameterization
with multiple cloud base levels
and exponential mass-flux profile will also
be shown.
