Abstract:

An atmospheric general circulation model for climate studies (CCSR/NIES AGCM) is developed. The model uses spectral transformation method in horizontal and grid differentiation on sigma coordinate in vertical. The physical parameterization includes a sophisticated radiation scheme with two-stream k-distribution method, simplified Arakawa-Schubert cumulus scheme, prognostics of cloud water scheme, turbulence closure scheme with cloud effect, orographic gravity wave drag, and a simple land-surface submodel. The model also includes plug-in compatible alternative physical parameterization schemes and a slab mixed-layer ocean as optional modules.
