“…Downward movements in anticyclones lead to an additional lowering of the pycnocline and its maximum deepening. Convergence in anticyclones leads to the surface water accumulation, which causes an increase of cold storage in their cores to maximum values and intensive formation of CIL waters [11,13,23,36,37]. The accumulation of surface waters with the same properties and the lowering of the main pycnocline contribute to the weakening of the upper layer stratification in anticyclones [13].…”

“…Convergence in anticyclones leads to the surface water accumulation, which causes an increase of cold storage in their cores to maximum values and intensive formation of CIL waters [11,13,23,36,37]. The accumulation of surface waters with the same properties and the lowering of the main pycnocline contribute to the weakening of the upper layer stratification in anticyclones [13]. The authors of [36] show that MLD in the Sevastopol eddy can reach high values excessing 50-60 m. In winter, the RMS deviation for the MLD values is quite large and is 10 m for the central part of the sea and 15 m for the continental slope area.…”

“…To study the effect of eddies on MLD, the method of composite analysis of altimetry and hydrological data was used [13]. Mesoscale eddies were identified by geostrophic velocity data obtained from measurements of satellite altimeters.…”

“…Since the main pycnocline is lowered in anticyclones, in January MLD in these eddies sharply increases. The deepening of the pycnocline is determined by intensity of the eddies [13] and it can be expected that in the most intense anticyclones MLD can reach even greater values.…”

“…The intensity of the large-scale circulation at seasonal and interannual scales is determined by the wind vorticity [8][9][10]. Vertical movements in mesoscale eddies also lead to a significant change in the position of isopycnic surfaces [11][12][13]. For example, in anticyclones, the depth of the pycnocline may deepen by 50 m, and in cyclones, the pycnocline can rise by 40 m relative to unperturbed values [13].…”

Spatio-temporal variability of the mixed layer depth (MLD) in different areas of the Black Sea in 1985-2017, its relationship with basin dynamics and atmospheric forcing are studied. Methods and Results. The study is based on the hydrological data archive for 1985-2017 including the measurements of the ship expeditions, the Argo buoys and the moored buoy "Aqalog". Seasonal and interannual variability of the mixed layer depth was determined using the density criterion (dr = = 0.07kg/m 3) between the surface layers and the base of the upper mixed layer. Conclusions. In January-March, the large-scale and mesoscale dynamics significantly affects the mixed layer depth variability. Minimum monthly average values of the mixed layer depth in winter are observed in the mesoscale cyclonic eddies and in the center of the sea (20-30 m), the moderate valueson the periphery of the basin (40-45 m) and the maximum onesin the mesoscale anticyclones (60-70 m). Several times the mixed layer depth values exceeding 150 m were detected in the downwelling areas of the basin. Analysis of the whole period (1985-2017) shows that the mixed layer density was never more than 1015 kg/m 3. This isopycnal limits the maximum possible depth of the upper mixed layer. The impact of wind velocity on the spatial and temporal variability of the mixed layer thickness is the largest in spring and autumn when the seasonal thermocline is weak. It is less important in summer when solar heating stabilizes the upper layer, and in winter when the mixed layer depth is large. Rise of the mixed layer depth in summer is observed in recent years that is associated with rise of the wind speed in a warm period of a year.
