| Summary: | Outline of the model Global warming studies at the Meteorological Research Institute (MRI) were started in the late 1980s. A coupled atmosphere-mixed layer ocean model was developed for this purpose and was applied for a quasi-equilibrium experiment under a doubled atmospheric CO2 condition. The atmospheric model (Tokioka et al., 1984) used has its top at 100 hPa and 5 layers and a regular 5 ° by 4 ° longitude/ latitude resolution. The model incorporates the radiative model by Katayama (1972), Arakawa-Schubert cumulus parameterization (Arakawa and Schubert, 1974), the planetary boundary layer (PBL) model proposed by Randall and Arakawa and the ground surface model by Katayama (1972). The effect of the ocean is included simply as a 50 m slab without horizontal heat transport. Sea ice is parameterized following the energy-balanced zero layer model by Semtner (1976). Because the heat flux by the ocean is completely neglected, the coupled model is not free from model biases caused by the neglect of the oceanic heat transport. The meridional temperature gradient is certainly |
