One-dimensional mixed layer ocean and sea ice model with prescribed oceanic heat transport
December 1995. We describe a simple two-layer thermodynamic ocean-ice model, which has been developed for coupling to an atmospheric general circulation model (GCM). The model ocean is thermally active above the annual mixed layer maximum. It consists of an upper mixed layer, which exchanges heat wi...
