Short summary
In sea ice models, the flow rule determines how sea ice deforms (opening, closing and shearing) when critical stresses are reached. We implemented in CICE a novel approach to define the flow rule. This is a useful capability as it allows to independently optimize critical stresses and deformations. As opposed to the standard flow rule, the novel approach can lead to a thicker and more active sea ice cover with narrower deformations.
