Seasonal and interannual variability of the Ekman pumping velocity in the Black Sea is studied based on ERA-Interim reanalysis data of 10 m wind speed for the period 1979?2015. Upward Ekman pumping prevails in the annual cycle due to the predominance of the cyclonic wind curl over the Black Sea. The maximum upward Ekman pumping occurs in winter. In June, the basin averaged pumping velocity is directed downwards. The magnitude and spatial distribution of the Ekman pumping velocity depends on the direction of the wi...
