{{Refimprove|date = August 2015}}The Reading '''Intermediate General Circulation Model''' ('''IGCM'''), is a simplified or "intermediate" [[Globalglobal climate model]], which is developed by members of the [http://www.reading.ac.uk/meterology Department of Meteorology]{{Dead link|date=January 2020 |bot=InternetArchiveBot |fix-attempted=yes }} at the [[University of Reading]], and by members of the [http://www.meteo.mcgill.ca/bourqui/ Stratospheric Dynamics and Chemistry Group] of the [[McGill Atmospheric and Oceanic Sciences|Department of Atmospheric and Oceanic Sciences]] at [[McGill University]].
The IGCM is based on the primitive-equations [[Baroclinity|baroclinic]] model of Hoskins and Simmons, which has been converted to run on workstations. Several variations have been developed by adjusting representations of the physics.
