“…Anticyclonic circulation was detected at depths below 800 m with current velocities reaching 1.5 cm/s. The intensity of the deep-water longshore anticyclonic circulation in the presented calculations turned out to be lower than in [21].…”

“…In these figures, the anticyclonic circulation is clearly visible at depths of 800 m with current velocities reaching 1.5 cm/s. The depth of the anticyclonic circulation is somewhat lower than the previously mentioned layer-by-layer estimates of mean velocities below the main pycnocline (100-300 m) [21]. This may be a consequence of previously detected temperature deviations of the model and measured values in the 800-1500 m layer.…”

“…The deviation in the 800-1500 m layer is explained by the fact that here the data of ARGO floats on temperature are very different from the mean monthly climatic data, which at depths below 150 m the model data is linked to. In addition, this may indicate increased temperature variability in the 800-1500 m layer, leading to the intensification of currents, found in [21].…”

“…The previously discussed deterioration of the consistency of the compared data in the main pycnocline layer (100-300 m) is also traced. Due to the fact that the ARGO floats do not measure the current velocities directly, validation of model currents is possible only on the basis of the mean current velocities in the deep-water layers calculated in [21] according to their movement data. In accordance to the layer-by-layer estimates of the mean velocities obtained in this work, it is believed that below the main pycnocline (100-300 m) they are ~ 4 cm/s, and in the layer of 800-1200 m they increase to 6 cm/s.…”

If we take into account all the data processed, the highest values of mean velocities are observed in January -March, and the lowest -in June -October [21].…”

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. Conclusion. 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.Acknowledgements: the research was carried out within the framework of scientific projects No. 18-05-00353 and No. 18-35-00512 at the RFBR financial support.For citation: Korshenko, E.A., Diansky, N.A. and Fomin,
