Абстракт
The algorithm for splitting k- turbulence equations is used to parameterize viscosity and diffusion coefficients in the ocean general circulation model. The k- equations are split into stages describing the transport-diffusion and generation-dissipation of the turbulent kinetic energy and frequency function . At the generation-dissipation stage, the equations are solved analytically. Calculations of circulation in the North Atlantic-Arctic Ocean for 1948-2009 have been carried out. The experiments demonstrate an adequate reproduction of hydrophysical characteristics and high efficiency of the algorithm. It is shown that considering the climatic annual mean buoyancy frequency in the turbulence equations at the generation-dissipation stage is an important factor in improving the accuracy of simulated fields.
