Purpose. The purpose of the study is to analyze wind conditions leading to the occurrence of coastal upwelling events off the Southern Coast of Crimea (Katsiveli) in the Black Sea based on the calculations of wind upwelling index. Methods and Results. The 6-hour ERA5 reanalysis data of surface wind speed components, long-term measurements of seawater and air temperature near the coast in Katsiveli (1992-2021), as well as satellite maps of sea surface temperature are used. The upwelling index is calculated as Ekman transport driven by alongshore winds. The index is considered to be positive when the transport is directed offshore. For the Katsiveli area, this condition corresponds to winds with a western component. Negative values of the index and onshore water transport correspond to eastern winds. Calculations of the upwelling index shown that the most favorable wind conditions for upwelling events are observed in winter (December and January) and summer (June and July), driven by the high frequency of western winds...
