An analysis of the velocities of drifters in the vortex structure in the northwestern part of the Black Sea is carried out. Drifters were deployed in an anticyclonic eddy, previously identified from satellite images. The rotational and transport components of the velocity in the eddy are calculated. A good agreement between the calculated velocities of the vortex center displacement based on drifter data and sequential satellite images obtained from AVHRR, MODIS scanners in the optical and infrared ranges was demonstrated. The trajectories of drifters rotation are elliptical with the ratio of the lengths of the axes 1.2–1.3. The ellipse axes rotate clockwise. It is shown that the frequency of velocity change in a vortex is about twice as much as the rotation frequency. That is characteristic of elliptical motion with a constant angular velocity. The direct effect of wind amplification on the displacement of the entire vortex structure has been demonstrated.
