The article is dedicated to the study of hydrometeorological parameters on a stationary oceanographic platform in the Black Sea. The research paper contains the description developed in the Marine Hydrophysical Institute’s complex for measuring meteorological parameters (wave height, wind speed and direction, free-air and sea temperature, barometric pressure, relative humidity). The measurements were carried out on a stationary oceanographic platform located in the coastal zone of the southern coast of Crimea at a distance of 600 m from the shore. The wind speed and direction sensor was located at a height of 21 m, the sampling resolution was 0.2 Hz. The wind speed was reduced from 21 m to the standard height of observation by the formula assuming the existence of a logarithmic sublayer. The sensors of atmospheric pressure, relative air humidity, air temperature were located at a height of 13 m, the sampling resolution was 1 Hz. The depth of immersion of the water temperature sensor was 1-1.5 m. As a result of the analysis of more than 52,000 hour records of meteorological parameters during 2011-2018, the regime and extreme characteristics for the study area were estimated. The average monthly wind speed in summer is approximately 4.6-4.8 m/s, and in winter - 6-6.5 m/s. The maximum wind speeds on the SOP reached values of 19-26 m/s, and gusts - 39 m/s. The average monthly air temperature varies from 7.3 °C in February to 25.6°C in August. The average annual humidity is 73%. The average monthly temperature of sea water varies from 10.1 °C in February-March to 23.7 °C in August. Seasonal variation is present in the average monthly values of the atmospheric pressure: the lowest values (1006.1 hPa) are observed in July and the highest (1016.1 hPa) - in December.
