global climate models

Synonyms

general circulation model,

Definition

A mathematical model of the general circulation of the planet’s atmosphere or oceans based on mathematic equations that represent physical processes. These equations are the basis for complex computer programs commonly used for simulating the atmosphere or oceans of the Earth. GCMs are widely applied for weather forecasting, understanding the climate, and projecting climate change. (UKCIP)
