In the central part of the Sea of Azov for the period 2003-2018, cases of intense cyanobacteria blooming were detected in satellite data of high and medium resolution. Such events were observed from 2005 to 2010, and in 2012-2013. The longest of these blooms occurred in 2005, 2006, and 2009. The influence of temperature and wind conditions as well as incoming river discharge on the development of these cyanobacterial blooms is considered. Intense blooms were most often observed at high temperatures of the surface water layer (from 24-26 °C), but in 2005 and 2006 they were also observed at water temperatures of 18-20 °C. It was found that sustained low wind speeds are favorable conditions for the evolution of intense cyanobacterial blooms. An increase in wind speed values from 8-10 m/s and above causes their degradation. A decrease in the volume of river discharge may be one of the reasons for a decrease in the incidence of intense blooms in the later years of the study period. © 2021 Space Research Institute of the Russian Academy of Sciences.
