Parallel Climate Model (PCM) Effort at ORNL
Collaborative PCM Projects
-
The Parallel Climate Model,
is developed and managed by Warren Washington's group at NCAR. This model
is important for much of the DOE participation in the Global Change
Research Program. A version of the atmospheric model component was
adapted for distributed memory parallel computers along the lines
of the 2 dimensional domain decomposition in PCCM2. The atmospheric model
was upgraded to CCM3.2 physics and dynamics. Recent performance studies of
this model (CCM3/MP-2D) are shown on

Parallel Climate Model Ensemble Calculations,
on the IBM SP. We are providing support for Warren Washington's
group in managing the many, long runs and adapting the program
to run efficently. First case (B06.05) was an historical run
shepherded by ORNL folks. NCAR users added in Feb.2000 to shepherd
subsequent ensemble runs. Results archived at PCMDI at LLNL and NERSC.

High resolution case
To explore the next generation model resolution and get forecasts
appropriate for downscaling studies, a T85 (1.4 degree) horizontal
atmospheric resolution model is being studied.

Highlights of simulations show the realistic
ENSO patterns generated by the PCM simulation.
