Abstract

Purpose. The present paper is focused on theoretical analysis of hydrophysical characteristics of the Black Sea in 2011.

Methods and Results. The Black Sea hydrophysical characteristics are calculated using a version of the marine circulation σ-model (Institute of Numerical Mathematics Ocean Model – INMOM) for the Black, Azov and Marmara seas (BAMS) with high spatial 1 km resolution and 20 σ-levels distributed non-uniformly over the depth. Quality of the simulated salinity and temperature fields is assessed by their comparison with the data of the ARGO deep-profiling floats available for the period under consideration. Degree of correspondence of the modeled current fields to the observed ones is estimated based on the average deep-sea current velocities calculated from the data on the Argo profiling floats’ movements.

Conclusions. The comparative analysis results show that the INMOM adequately reproduced vertical distribution of the Black Sea hydrophysical characteristics. Comparison of the simulated temperature and salinity fields with those derived from the ARGO buoys data demonstrates the fact that the strongest deviations of the characteristics under study are observed in the sea upper layers (0‑100 m); whereas in the deep-water layers (300–1500 m), the degree of consistency between the simulated results and the field data is much more higher. On the depths below 800 meters, the deep-sea anticyclonic flows with the velocities attaining 1.5 cm/s are present. The revealed feature is not typical of the generally accepted scheme of the Black Sea cyclonic circulation.
