Abstract
The present modeling results support a view that the surface resulting circulation of waters in the Kara Sea is cyclonic, including one large-scale gyre in the south-western part of the Sea, one mesoscale gyre in the eastern part of the Sea and differently directed currents in the southern, central and northern parts of the Sea. The use of a high-resolving grid allows to reveal two mesoscale gyres in the south-western part of the Sea and an additional six mesoscale gyres having a different direction of rotation in the remaining part of the Sea. A comparison of two solutions performed, obtained for the overall (tidal + wind+ thermohaline) and combined (wind + thermohaline) forcing allows to quantify a contribution of tides to the formation of surface resulting circulation of waters. It turns out that tides introduce detectable changes in this circulation which origin is assumed to owe to wind and thermohaline factors.
