### general circulation model

**(GCM)**
(climate model of a planet's atmosphere or ocean)

A **general circulation model** (**GCM**)
is a mathematical climate model of
the general circulation of a planet's
atmosphere or ocean.
It incorporates fluid dynamics
(Navier-Stokes equations), rotation,
and thermodynamics.
Such a model can be analytic
or can be fleshed out with
computer-based numerical simulations.

Such models have been developed for the
Earth, but also adapted to other
planets and moons. With the study
of extra-solar planets, there is much
opportunity for using them.

**GCM** can also stand for **global climate model**,
and detailed global climate models can be
general circulation models.
