Purpose. The study is purposed at analyzing frequency, speed and duration of the alongshore winds inducing the Ekman upwelling near the Southern Coast of Crimea. Methods and Results. The 6-hour data on the wind speed components at the 10 m height derived from the ERA5 atmospheric reanalysis for 1979-2021, as well as the data of temperature monitoring performed at the Black Sea hydrophysical sub-satellite polygon of Marine Hydrophysical Institute, Russian Academy of Sciences, are used. Frequency and speed of the winds (namely, the southwestern, western and northwestern ones) favorable for development of upwelling near the Southern Coast of Crimea are considered. The multi-year data based calculations show that the seasonal variability in frequency of each of these winds is of an individual character, whereas their average speeds change the same decreasing from winter to summer. In summer, frequency of the western and northwestern winds increases, and that of the southwestern ones - decreases...
