This work presents the results of modification of the ocean climate model of the Institute of Numerical Mathematics (INM) RAS. The main code changes are related to the revision of the dissipation calculation of the horizontal velocity components, isopycnal diffusion and also to modifications of schemes of time integration of scalars and the components of velocity. Test runs conducted with the CORE-II protocol demonstrated that the proposed changes lead to a significant increase in the computational efficiency of the ocean climate model.
Keywords: climate modelling; terrain-following ocean model; parallel scalability.
