“…It was taken into account that the accumulation of the accessible potential energy in the baroclinic layer occurs throughout the entire wintertime [5,28]. Indeed, the peak of the maximum wind field vorticity is recorded in January, while the maximum intensification of currents occurs in March.…”

“…Long-periodic oscillations of the pycnocline position were revealed in [27]. Studies of the interdecadal variability of the accessible potential energy for August showed the presence of the energy maximum over the period from 1961 to 1970 and its minimum, from 1976 to 1985 [28]. Gradual strengthening of stratification in the pycnocline layer was revealed from the 1960s to the 1980s [3].…”

The Black Sea density fields and geostrophic circulation in the 0-300-dbar layer are reconstructed from the February archive hydrological data for several decades from 1951 to 1995 and then their interdecadal variability is studied. A gradual rise of the pycnocline is noted in the dome region of large-scale cyclonic gyrals from 5 m at the top of the pycnocline to 10-15 m at 100-300-m levels. Differently directed tendencies of long-term variability of the winter circulation are revealed: circulation intensification in the upper 0-50-m layer (except for the southwestern sea) and weakening in the lower pycnocline 200-300-m layer. The connection with the wind vorticity variability, river runoff, precipitation, and air temperature is analyzed. Strengthening of the cyclonic wind vorticity in the 1960s and the early 1970s is in good agreement with the circulation intensification of that time in the eastern sea.
