“…In the study we use the free-surface, primitive equation, z-level numerical Model for Enclosed Sea Hydrodynamics (MESH), described by Ibrayev (2001), employing Boussinesq and hydrostatic approximations. Formulation of freesurface condition in the model allows propagation of surface gravity waves and mean sea surface elevation changes in response to non-zero water balance.…”

Abstract.A three-dimensional primitive equation model including sea ice thermodynamics and air-sea interaction is used to study seasonal circulation and water mass variability in the Caspian Sea under the influence of realistic mass, momentum and heat fluxes. River discharges, precipitation, radiation and wind stress are seasonally specified in the model, based on available data sets. The evaporation rate, sensible and latent heat fluxes at the sea surface are computed interactively through an atmospheric boundary layer sub-model, using the ECMWF-ERA15 re-analysis atmospheric data and model generated sea surface temperature. The model successfully simulates sea-level changes and baroclinic circulation/mixing features with forcing specified for a selected year. The results suggest that the seasonal cycle of wind stress is crucial in producing basin circulation. Seasonal cycle of sea surface currents presents three types: cyclonic gyres in December-January; Eckman south-, south-westward drift in February-July embedded by western and eastern southward coastal currents and transition type in August-November. Western and eastern northward subsurface coastal currents being a result of coastal local dynamics at the same time play an important role in meridional redistribution of water masses. An important part of the work is the simulation of sea surface topography, yielding verifiable results in terms of sea level. The model successfully reproduces sea level variability for four coastal points, where the observed data are available. Analyses of heat and water budgets confirm climatologic estimates of heat and moisCorrespondence to: R. A. Ibrayev (ibrayev@inm.ras.ru) ture fluxes at the sea surface. Experiments performed with variations in external forcing suggest a sensitive response of the circulation and the water budget to atmospheric and river forcing.

The results of research directed to the construction of a model for four-dimensional analysis of the ocean with a high spatial resolution are presented in the paper. These are, first, the development of the dynamic core of a hydrostatic ocean model; second, the study of some important physical phenomena in the Arctic and approaches to their simulation; third, the results of application of the dynamic-stochastic data assimilation method in the model of the tropical region of the Atlantic Ocean.

The INM IO numerical World Ocean model is verified through the calculation of the model ocean climate. The numerical experiment was conducted for a period of 500 years following the CORE I pro tocol. We analyze some basic elements of the large scale ocean circulation and local and integral character istics of the model solution. The model limitations and ways they are overcome are described. The results gen erally fit the level of leading models. This experiment is a necessary step preceding the transition to high res olution diagnostic and prognostic calculations of the state of the World Ocean and its individual basins.
