“…Our analysis of climate change in SAT of the Black Sea-Sea of Azov region (1980-2020) and SST of the Black Sea (1982-2020) using NASA MERRA-2 satellite datasets [29] and the NOAA OI SST v2 high resolution dataset [38], respectively, as well as a comparison of the obtained temporal variability of the average annual SST in the Black Sea with the available data on the SST of the Sea of Azov in different years [9,3] showed that warming of these southern seas was observed throughout the entire period considered. The linear trend of the average annual SST in 1982-2020 in the Black Sea as a whole was +0.052°C/year, and the average annual water temperature, since 2010, often exceeded 16°C (maximum 16.71°C in 2018).…”

“…The nature of the variation in the average annual SST values over time in the Black and Azov Seas is on average the same [5,16]. According to Dashkevich and Kulygin [9], in 1982-2015, an increase in the average annual SST (on average) in the Sea of Azov itself and in Taganrog Bay was observed; the increase in 2000-2015 versus 1982-1999 averaged 0.95°C in the sea and 0.84°C in the bay. An increase in the average annual SST was observed from the mid-1990s to 2010 (trends of +0.05°C/year in the sea itself and +0.04°C/year in the bay); then, until 2015, a slight decrease was observed.…”

“…The highest average annual SST in 1982- 3), i.e., ~2.8°C higher than the average annual SST of the Sea of Azov. In 2019, the average annual SST in Taganrog Bay was 13°C [3]; therefore, in the Sea of Azov itself, it was several tenths of a degree higher (within 0.7°C, as comparison of the data in [9] shows). In the Black Sea in 2019, the average annual SST was 16.34°C (Fig.…”

Climate Change in the Hydrometeorological Parameters of the Black and Azov Seas (1980–2020)

To study the nature of climate change in the hydrometeorological parameters of the Black and Azov Seas—surface air temperature (SAT), sea surface temperature (SST), ice cover, and sea level—under conditions of ongoing global warming, we used reanalyses and remote sensing data, as well as information from known publications of recent years. It was found that against an increase in SAT over the Black–Azov Sea region (+0.053°C/year in 1980–2020) and SST of the Black Sea (+0.052°C/year in 1982–2020), the values of these parameters in the 2000s differ significantly from those in the 1980s–1990s: the maximum average monthly summer and minimum average monthly winter temperatures have increased, as well as the number of mild winters. The average annual SST of the Black Sea, which practically did not exceed 15°C in the 1980s–early 1990s, has exceeded 16°C in most cases since 2010 (maximum 16.71°C in 2018). In the 2010s, the average monthly winter minima, with the exception of the winters of 2011/2012 and 2016/2017, did not fall below 8°С. A consequence of the increase in winter temperatures was a decrease in the ice concentration in the Sea of Azov (the trend of the mean monthly concentration is –1.2%/10 years). From about 2004–2010 in the Black Sea and since 2004 in the Sea of Azov, the tendency towards increase in their levels (on average) has been replaced by a slight decrease, so that the average positive trends for the period 1993–2020 (+0.32 ± 0.16 cm/year in the Black Sea and +0.21 ± 0.05 cm/year in the Sea of Azov) were approximately 2.5 times less than in 1993–2012. The reason for this decrease in levels (on average) in the last 10–15 years was apparently a decrease in the incoming part of the freshwater balance of both seas, which is indirectly confirmed by the observed increase in salinity of their waters.
