GCM has various meanings in the Climate category. Discover the full forms, definitions, and usage contexts of GCM in Climate.
A general circulation model uses the same equations of motion as a numerical weather prediction model, but the purpose is to numerically simulate changes in climate as a result of slow changes in some boundary conditions.
ClimateHydrodynamic models of the atmosphere on a grid or spectral resolution that determine the surface pressure and the vertical distributions of velocity, temperature, density, and water vapor as functions of time from the mass conservation and hydrostatic laws, the first law of thermodynamics, Newton's second law of motion, the equation of state, and the conservation law for water vapor. Abbreviated as GCM. Atmospheric general circulation models are abbreviated AGCM, while oceanic general circulation models are abbreviated OGCM.
