Analysis of Seasonal Energy Characteristics of the Marmara Sea Upper Layer Dynamics

Purpose. The aim of the work is to assess role basic forces in formation dynamic structures upper layer Marmara Sea different hydrological seasons. Methods and Results. numerical model developed Marine Hydrophysical Institute, Russian Academy Sciences, was used calculate hydrodynamic energy characteristics sea circulation. horizontal spatial resolution 1.22 × 0.83 km, 18 horizons were vertically, time step 0.5 min. waters inflowing through Bosporus Dardanelles straits corresponded available observational data. On surface, daily average fields tangential wind stress, heat fluxes, precipitation evaporation for 2008 preset; these parameters calculated using regional atmospheric MM5. Spatial distributions vortex corresponding flows seasons considered. Having been analyzed, seasonal current velocity components kinetic budget showed that during year, vortices formed mainly by two mechanisms. In central part sea, generation a large-scale anticyclone its variability are basically conditioned forcing, whereas evolution coastal cyclonic eddies caused buoyancy force. where buoyancy, pressure friction forcing takes place, zones local extremes distinguished. Two them areas water inflow Bosphorus straits. strongest observed region certainly fact Black have decisive influence on nature extreme values other result coastline structure heterogeneities, leads eddies, source which potential energy. Conclusions. Analysis results performed experiment makes it possible conclude Sea, while those cyclones – effect
