Thermal oscillation induced by an interaction between sea ice and ocean in a numerical polar ice-ocean model

A numerical model of simplified Arctic Ocean and Greenland-Norwegian Seas is presented. The essential effects of sea ice, river runoff, surface cooling, and water exchange between the Greenland-Norwegian Seas and the Atlantic Ocean are included. A thermal oscillation occurs due to an interaction bet...

Description
Summary:A numerical model of simplified Arctic Ocean and Greenland-Norwegian Seas is presented. The essential effects of sea ice, river runoff, surface cooling, and water exchange between the Greenland-Norwegian Seas and the Atlantic Ocean are included. A thermal oscillation occurs due to an interaction between the sea ice and the ocean. The river runoff forms a low-salinity surface layer, which is essential to the oscillation. Parameters governing the time scale of the oscillation are also discussed.
