This paper reports the results from coarse-resolution World Ocean numerical experiments on simulation of the mechanism of the deep water formations in high latitudes of the North Atlantic and in the Southern Ocean. The global large scale geostrophic ocean circulation model with 5 degree resolution on latitude and longitude and 24 levels in the vertical coordinate is used. The surface temperature, salinity, and wind stress with annual cycle are specified from the climatological observed data. In this work, the model of global circulation of the World Ocean is added by the parameterization of the Mediterranean high saline water and including the corrections of the seasonal change surface temperature, salinity.
