Sea Ice Formation in a Coupled Climate Model Including Grease Ice
Abstract Sea ice formation processes occur on subgrid scales, and the detailed physics describing the processes are therefore not generally represented in climate models. One likely consequence of this is the premature closing of areas of open water in model simulations, which may result in a misrep...
