Abstract

Based on version 2 of the Louvain-la-Neuve sea Ice Model (LIM2), sensitivity experiments reveal simple relations between ice conditions and the characteristic thickness parameter ho that appears in the parameterisation used to determine changes in open water area during ice growth. In particular, when ho is increased, the ice concentration is decreased during ice growth and increased during the subsequent melting season; the annual mean sea ice volume, thickness and extent all increase with ho. Calibration of ho makes it possible to adjust the model-simulated ice volume and thickness variations to be consistent with observations.
