Physics part of GCM calculate the forcing terms in governing equations. Parameterizations of each physical process are following.
1. Simplified Arakawa-Schubert cumulus convection scheme based on Relaxed Arakawa-Schubert scheme (Moorthi and Suarez, 1992).
2. Large-scale condensation scheme based on Letreut and Li(1991)
3. Diffusion-type Shallow Convection.
4. 2-stream k-distribution radiation scheme (Nakajima and Tanaka,1986).
5. Bonan's Land Surface Model (Bonan 1996).
6. Non-local PBL/Vertical diffusion (Holtslag and Boville 1993).
7. Orographic gravity-wave drag (McFarlane, 1987).
8. Dry adiabatic adjustment
