Modeling of Long-Term Evolution of the Black Sea Hydrophysical Fields
In this work a long-term evolution of the Black Sea dynamics (1980-2020) is reconstructed by means of numerical simulation. The model of the Black Sea circulation is z-coordinate model with 4.8 km horizontal space resolution and 40 levels in vertical direction. Mixing processes in the upper layer are parameterized with Mellor-Yamada turbulent model. As the sea surface boundary conditions we used atmospheric forcing functions provided for the Black Sea region by CMCC using regional climate model COSMO-CLM. These data have a spatial resolution of 14km and a daily temporal resolution. To evaluate quality of the hydrodynamic fields derived from the modeling they were compared with in-situ hydrological measurements and also with similar results from physical reanalysis of the Black Sea.
