Climate models, also known as general circulation models or GCMs, use mathematical equations to characterize how energy and matter interact in different parts of the ocean, atmosphere, land.

This term often requires additional qualification (e.g., as to whether or not the atmosphere is fully coupled to an ocean–see ‘Atmosphere-Ocean General Circulation Model’). Simple Model of Global Circulation We can gain an understanding of how global circulation works by developing two simplified graphical models of processes that produce this system. The first model will be founded on the following simplifying assumptions: The Earth is not rotating in space. A general circulation model (also known as a global climate model, both labels are abbreviated as GCM) uses the same equations of motion as a numerical weather prediction (NWP) model, but the purpose is to numerically simulate changes in climate as a result of slow changes in some boundary conditions (such as the solar constant)or physical parameters (such as the greenhouse gas concentration).

Air flow for no rotation and no water on a planet. Global Circulations explain how air and storm systems travel over the Earth's surface. The global circulation would be simple (and the weather boring) if the Earth did not rotate, the rotation was not tilted relative to the sun, and had no water.

It is shown that by using detailed and high temporal resolution observed/forecasted meteorological fields within the model, the global model is able to capture the observed seasonal variability in atmospheric mercury concentrations. Downscaling Global Circulation Model Outputs: The Delta Method Decision and Policy Analysis Working Paper No. 1 Julian Ramirez-Villegas1,2,3 and Andy Jarvis1, 2 1 International Center for Tropical Agriculture, CIAT, Cali, Colombia 2 CGIAR Research Program on Climate Change, Agriculture and Food Security, CCAFS The model coupling consists of bidirectional data exchange between the global model and the high‐resolution LES models embedded within the columns of the global model. Our setup allows for selective superparameterization, that is, for applying superparameterization in local regions selected by the user, while keeping the standard parameterization of the global model intact outside this region. These early forecasting models were regional, not global in scale. It was not for practical reasons of weather prediction that a few meteorologists wanted to push on to model the entire general circulation of the global atmosphere. To be sure, Von Neumann and the military agencies that funded him speculated that GCMD - Global Circulation Model. Looking for abbreviations of GCMD?
