A General Circulation Model (GCM) is a mathematical climate model of the general circulation of a planet's Atmosphere or ocean. It incorporates fluid dynamics (Navier-Stokes Equations), rotation, and thermodynamics. Such a model can be analytic or can be fleshed out with computer-based numerical simulations. Such models have been developed for the Earth, but also adapted to other planets and Moons. With the study of Extra Solar Planets, there is much opportunity for using them. GCM can also stand for Global Climate Model, and detailed Global Climate Models can be General Circulation Models. Example models: Referenced by: MarsWRF MITgcm |
