Atmospheric model

Atmospheric model is constructed around the full set of primitive dynamical equations which govern atmospheric motions, and supplements these equations with optional parameterizations for turbulent diffusion, solar and terrestrial radiation, moist processes including the formation and interaction of clouds and precipitating liquid and ice hydrometeors, sensible and latent heat exchange between the atmosphere, multiple soil layers, a vegetation canopy, surface water, the kinematic effects of terrain, and cumulus convection. Most of the atmospheric models are numerical, i.e. they discretize equations of motion and they are able, depending on type of the model, to predict microscale phenomena such as tornadoes and boundary layer eddies, sub-microscale turbulent flow over buildings and in a wind tunnel, as well as synoptic, and global flows.
