Peculiarities of the generation of deep and bottom waters in the area of coastal flaw polynyas
Abstract
Peculiarities of the processes of interconnected salinity fields and flows in the patches of unfrozen water behind the icebound coastal areas are analysed according to the results of numerical simulation. A three-dimensional unsteady hydrostatic model is used. The initial salinity distribution is taken to be double-layer. The salt flow caused by intensive ice generation in a coastal flaw polynya is specified by means of boundary conditions. The structure of interaction of salinity fields and flows is given in the process of generation.
