Abstract:
The MRI model is derived from an earlier version of the University of California at Los Angeles (UCLA) model (cf. Arakawa and Mintz 1974 and Arakawa and Lamb 1977 ). Subsequent modifications include increases in vertical resolution, and changes in parameterizations of gravity-wave drag, atmospheric radiation, convection, surface characteristics, and land surface processes. The model is identical to latest AMIP model MRI GCM-IIb (4x5 L15) 1995, except for different initial conditions and the Earth's orbital parameters.
