Atmospheric models calculate winds, heat transfer, radiation, relative humidity, and surface hydrology within each grid and evaluate interactions with neighboring points. [1] A general circulation model (GCM) is a type of climate model. It employs a mathematical model of the general circulation of a planetary atmosphere or ocean.
Ocean general circulation models (OGCMs) are a particular kind of general circulation model to describe physical and thermodynamical processes in oceans. The oceanic general circulation is defined as the horizontal space scale and time scale larger than mesoscale (of order 100 km and 6 months).
Integrated ocean modeling systems is helpful for specific regions: for example, the ESPreSSO model is used to study the Mid-Atlantic Bight region. Integrated ocean modeling systems often use data from buoys and weather stations for atmospheric forcing and boundary conditions. Two examples of integrated ocean modeling systems are:
HadCM3 (abbreviation for Hadley Centre Coupled Model, version 3) is a coupled atmosphere-ocean general circulation model (AOGCM) developed at the Hadley Centre in the United Kingdom. [1] [2] [3] It was one of the major models used in the IPCC Third Assessment Report in 2001.
Atmospheric models calculate winds, heat transfer, radiation, relative humidity, and surface hydrology within each grid and evaluate interactions with neighboring points. [3] A general circulation model (GCM) is a type of climate model. It employs a mathematical model of the general circulation of a planetary atmosphere or ocean.
Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant.
HyCOM uses mainly the ocean portion of what is shown in this example. The Hybrid Coordinate Ocean Model (HyCOM) is an open-source ocean general circulation modeling system. [ 1 ] HyCOM is a primitive equation type of ocean general circulation model .
A General Circulation Model (GCM) is a mathematical model that can be used in computer simulations of the global circulation of a planetary atmosphere or ocean. An atmospheric general circulation model (AGCM) is essentially the same as a global numerical weather prediction model, and some (such as the one used in the UK Unified Model) can be ...
