Abstract

Within the framework of the numerical model of a two-layer ocean with the depth of layers corresponding to the average ocean conditions, the evolution of large-scale circulation under the action of an external stationary vorticity flow under constant dissipation parameters is studied, the time scales of long-period oscillations of the energy of flows are analyzed. The temporal variability of the enstrophy spectrum of the system of flows is considered, the connection of oscillations of the total energy of large-scale circulation with oscillations of the position of the center of mass of the enstrophy spectrum of the system is revealed.
