The effects of mixed layer dynamics on ice growth in the central Arctic.

The thermodynamic ice model of Thomdike (1992) is coupled to a one dimensional, two layer ocean entrapment model to study the effect of mixed layer dynamics on ice growth and the variation in the ocean heat flux into the ice due to mixed layer entrapment. Model simulations show (i) the existence of...

Description
Summary:The thermodynamic ice model of Thomdike (1992) is coupled to a one dimensional, two layer ocean entrapment model to study the effect of mixed layer dynamics on ice growth and the variation in the ocean heat flux into the ice due to mixed layer entrapment. Model simulations show (i) the existence of a negative feedback between the ice growth and the mixed layer entrainment; and (ii) the underlying ocean salinity has a greater effect on the ocean heat flux than does variations in the underlying ocean temperature. Model simulations for a variety of surface forcing and initial conditions demonstrate the need to include mixed layer dynamics for realistic ice prediction in the Arctic.
