Purpose. The aim of the study is to specify the features in changes of the Black Sea surface water temperature off the Crimea coast on a synoptic scale in summer 2022 based on the contact and satellite measurements of water temperature and surface wind. Methods and Results. The data of hydrological measurements carried out during the 122nd (June 7–23, 2022) and 123rd (August 16–31, 2022) cruises of the R/V Professor Vodyanitsky in the northern part of the Black Sea were used. Sea water temperature was measured by the CTD complex IDRONAUT OCEAN SEVEN 320 PlusM, and the wind speed and direction – by the AIRMAR-220WX ship meteorological station. The study also included the daily averaged satellite-derived data on sea surface temperature taken from the Black Sea – High Resolution L4 Sea Surface Temperature Reprocessed with the 0.01° × 0.01° spatial resolution, as well as the data on wind speed taken from the Global Ocean Hourly Sea Surface Wind and Stress from Scatterometer and Model with the 0.125° × 0.125° spatial resolution (Copernicus Marine Environment Monitoring Service). Based on the contact and satellite measurements, statistical characteristics of the water temperature and wind speed distributions were calculated. It was shown that the differences in temperature distributions revealed from the data of the two-stage surveys in the above-mentioned cruises had been conditioned by the features of a temperature seasonal cycle and by the synoptic variations of surface wind. A significant inverse correlation was found between the wind speed module and the temperature, the maximum level of which was observed in the western part of the survey area, approximately between Cape Aiya and Cape Sarych. Conclusions. It is shown that based on the contact and satellite measurement, in summer 2022, the values of synoptic temperature anomalies on the sea surface were the highest in the area of noticeable coastal shelf expansion, i.e., in the Feodosiya Bay and between Sarych and Ayu-Dag capes. The temperature synoptic changes were conditioned mainly by the variations in the local wind speed. © 2023, Yu. V. Artamonov, E. A. Skripaleva, A. V. Fedirko, N. V. Nikolsky
