Certain results of numerical simulation of processes in the Arctic Ocean

Variations in hydrophysical parameters in the Arctic Ocean and the North Atlantic are studied on the basis of numerical simulation with the use of an ocean circulation model (including ice formation and drift). The main circulation and ice-drift modes have been ascertained depending on atmospheric cycles. The possibilities of the parameterization of intermediate and deep water formation in numerical models of polar ocean dynamics are considered. The effect of the interannual variability of the discharge of Siberian rivers on the distribution and propagation of fresh water in this region are estimated from numerical experiments. The simulation results of the propagation of the dissolved methane from Siberian rivers are presented.
