Abstract

Abstract

Thermodynamic coupling plays an important role in the simulation of sea ice and general oceanic circulation.It is an important factor to represent the ice-ocean interaction.It is necessary to copy with such a process with detailed tur bulence model,however,this treatment is limited by computation especially for the climate model. And the temper ature of the upper oceanic mixed layer in ice zone was assumed at the freezing point of seawater, which is often set to a constant,in most of the ice models and coupled ice-ocean models.Such an assumption is exact enough for the inner ice zone.But there exist exceptions when ice floe advects to a warmer waters in the marginal ice zone or when the freezing point varies with the salinity of seawater under ice bottom for salt rejection while freezing or for freshening while melting.A new thermody namic coupling scheme is presented according to the energy balances between the coupled ice-ocean system.The scheme neither keep the temperature of the mixed layer at the freezing point of seawater nor consider the detailed turbulent processes at the ice-ocean interface.
