Sažetak
The winter situation in a shallow land-locked basin modelling the Adriatic Sea is considered. During the winter the maximum of density is usually observed in the central part of the Adriatic, supporting thermohaline circulation characterized by upwelling along the coasts and downwelling prevailing over a greater part of the sea. Due to deflecting influence of the Coriolis force, long-shore currents appear as well. The present work encompasses two models having different types of friction parametrization. The first one allows for the vertical component of turbulent friction only, the other includes lateral friction as well. Both models give similar results and predict cyclonic circulation in the horizontal plane and downwelling in a greater part of the basin compensated by upwelling along the coasts, in fair agreement with the obesrvations. The modelling results are discussed for varying coefficients of bottom friction, vertical friction and lateral friction.
