Dynamical Meteorology and Climatology Unit

The Modular Arbitrary-Order Ocean-Atmosphere Model: A coupled ocean-atmosphere model to explore the impact of such coupling on the atmosphere variability.

The atmospheric component of the model is based on the papers of Charney and Straus (1980), Reinhold and Pierrehumbert (1982) and Cehelsky and Tung (1987), all published in the Journal of Atmospheric Sciences. The ocean component is based on the papers of Pierini (2012), Barsugli and Battisti (1998). The coupling between the two components includes wind forcings, radiative and heat exchanges.

Documentation is included with the code.
