Abstract
The effects of penetrating short-wave radiation on the Arctic Ocean water temperature and sea ice state have been studied with an ocean-ice general circulation model. Numerical experiments show that during summer period, while the ice thickness is reduced to 2 m, the absorption of penetrating radiation results in the formation of the subsurface temperature maximum. This temperature maximum gradually decays during the fall season due to strong vertical mixing and heat flux to the ice and underlying waters.
