Abstract

Abstract: Sea ice lateral melting parameterization scheme of Community Sea Ice Model version 5(CSIM5) is described in detail. Then we used the CSIM5 to simulate the effect of Sea ice lateral melting parameterization scheme on the change of the thickness and area of sea ice. The results show that: (1) Lateral melting thermal process will decrease sea ice thickness and sea ice area. The significant thickness ablation regions distribute in the Siberian Sea and the Greenland Sea and significant the sea ice area of ablation regions distribute around sea ice edge region ; (2) Lateral melting impact on sea ice thickness more obvious in summer than in winter, impact on sea ice area more significant in winter than in summer ; (3) The lateral melting scheme can better simulate the sea ice area seasonal changes;(4) Sea Surface Temperature (SST) is the very important impact factor on the sea ice lateral melting process and the large values of the lateral boundary melting rate distribute near the SST zero line .
