摘要: Landfast ice covers large surface areas of the winter Siberian Seas. The immobile landfast cover inhibits divergent and convergent motion, hence dynamical sea growth redistribution, decouples river plumes in coastal seas from atmosphere, positions polynyas at edge offshore. In spite potentially effects, state-of-the-art numerical models usually do not represent its correct extent. A simple parametrization based on bathymetry internal strength is introduced effects simulated Arctic Ocean are demonstrated. simulations suggest that impacts halocline stability through enhanced brine production located closer to shelf break by redirecting water Canadian Basin. These processes strengthen Basin, but erode Makarov Eurasian Basins.
