Abstract
The paper analyzed the simulation results of the Black Sea circulation in 2011 and 2016. Numerical experiments were carried out with a horizontal resolution of 1.6 km and took into account the real atmospheric forcing SKIRON. The simulated temperature and salinity were compared with observations. It revealed the correspondence to real data except some deviations caused by the movement of intensive mesoscale eddies. Analysis of velocity fields showed that the reducing of the wind influence in 2016 led to the weakening of the Rim Current in contrast to 2011. The Sevastopol anticyclone in the spring-summer of 2011 was weaker than in 2016, but the Batumi anticyclone was stronger in 2011 due to intensification of coastal circulation near the Anatolian coast. The eddy energy associated with mesoscale variability had been growing in 2011 due to both barotropic and baroclinic instability processes. The eddy energy had been decreasing during 2016 and started increasing only at the end of 2016 due to development of baroclinic instability processes.
