Abstract

This study analyzes the daily sea surface temperature from the Copernicus database on a grid with a spatial resolution of 0.05° × 0.05°. It calculates the characteristics of total sea surface temperature variability and seasonal variations across multiple temporal scales. A regional synthesis of these characteristics was performed for four areas along the Black Sea coast of the Crimean Peninsula over the 1991–2020 climate period. Characteristics of seasonal and interannual/decadal variability were evaluated using monthly averages, the main part of the synoptic range was evaluated with 10-day averages and the low-frequency part of the mesoscale band was analysed using daily averages. The results show distinct regional patterns. Karkinit Bay differed significantly from the other regions, exhibiting the largest seasonal range and the highest intensity of variability across all bands during winter. The Western region demonstrated the lowest level of temporal variability in all parameters. The Kerch-Feodosia shelf exhibited the highest variability across all bands in autumn. The Southern Coast of Crimea held an intermediate position in terms of temporal variability characteristics between the Western and Kerch-Feodosia regions. Overall, the shelf zone of the Crimean Peninsula shows enhanced regional contrast in sea surface temperature variability across different temporal scales compared to the open Black Sea. One of the primary drivers of these intense water temperature fluctuations is the occurrence of upwelling and downwelling events, which are linked to the variability of wind fields over the region.
