“…The numerical analysis of currents according to the described model can be performed by using various methods, e.g., the diagnostic method, i.e., for a given density field, or various modifications of the adaptation method [8]. Note that the adaptation method gives more consistent temperature, salinity, and velocity fields.…”

“…However, the application of this method to shallow-water basins, such as the Balaklava Bay, leads to strong smoothing of all calculated fields. As a result, some actually existing small-scale specific features of these fields often "disappear" [8,9]. Since the indicated small-scale features can be quite important for the description of the transport processes in the analyzed bay, we use the diagnostic method.…”

The Princeton Ocean Model is adapted to the water area of the Balaklava Bay for the numerical analysis of circulation. The calculations are performed with the help of the diagnostic method by using the data of the hydrological survey carried out in the bay in August 1992. We study the structure of the surface and bottom currents in the analyzed period as well as the vertical circulation of waters and the circulation averaged over the depth. The obtained three-dimensional fields of currents are used for the numerical analysis of the process of propagation of passive contaminating impurities from the sources located on the coasts of the Balaklava Bay.

The vertical variability of the geometric, dynamic, and thermohaline characteristics of Black Sea eddies is studied using three-dimensional identification of closed streamlines based on the results of simulations of the NEMO model in 2006–2016. The vertical extent of eddies depends linearly on their orbital velocity and significantly affects the speed of their translation motion. The influence of the background current on the upper part of the eddy leads to the mean tilt of the vertical axis of anticyclones in the cyclonic direction and this tilt is maximum in the zone of the Black Sea Rim Current. The eddies occupying the upper layer (up to 150 m) move relatively quickly at a speed of 0.08–0.14 m/s, since they are advected by the Rim Current. The most intense eddy dynamics is observed over the continental slope in the upper 20–70 m layer, where the probability of observing eddies exceeds 30%. Several maxima appear in the surface layer on the shallow northwestern shelf near the mouths of the Danube, Southern Bug, and Dnieper rivers. The relationship between the orbital velocity of eddies, their thermohaline structure, and stratification were estimated. Stability decreases in anticyclonic eddies within the layer 40–100 m due to the lowering of the pycnocline, and in cyclones it increases due to its elevation; in the underlying layers a compensating change of the opposite sign is observed. However, as the orbital velocity increases in the eddies of both signs, a decrease in stratification occurs in the upper 0–100 m layer, which is probably associated with an increase in the vertical shear of the current velocity. Three-dimensional identification of eddies makes it possible to track in detail changes in the individual characteristics of an eddy during its evolution. Using the example of an eddy off the Anatolian coast, it is shown that intensification of anticyclones is associated with the processes of entrainment of shelf waters, which can be one of the important sources of potential energy for anticyclones in the Black Sea.
