Abstract:
One of several versions of global spectral models in use at the Geophysical Fluid Dynamics Laboratory, ithis version of the GFDL model is applied primarily to climate studies. In its treatment of atmospheric dynamics, the model is similar to the GFDL Dynamical Extended-Range Forecasting (DERF) model (cf. Gordon and Stern 1982 and Miyakoda and Sirutis 1986 ), but it displays a number of differences in numerical features (e.g., use of rhomboidal rather than triangular spectral truncation and a somewhat higher vertical resolution), as well as in some model parameterizations (e.g., radiation, vertical diffusion, land surface submodel, sea ice submodel).
