Abstract:
In this paper, based on the numerical large-scale geostrophic ocean thermohaline circulation model, the influence of a numerical time step for modeling the large-scale temperature and salinity fields with the use of an implicit time integration method is investigated. It is shown that for a more adequate description of processes of a deep vertical convection and modeling a more realistic ocean thermohaline circulation, it is necessary to apply time steps no more than 10 days. At such time steps, the influence of numerical viscosity (diffusion) is insignificant.
