Abstract
Climate vulnerability of the Crimean Peninsula is assessed based on the temperature and precipitation changes for the period 1991–2021 and satellite-derived drought index (VHI) variations for the period 2001–2021. There is an increase of temperature on average by 0.78±0.01 °C per 10 years in summer, and a slight change in precipitation in June and July (within 2±1%). While in August there is a decrease of the precipitation amount by 10–12%. According to analysed data, the most severe drought condition manifestation on the Crimean Peninsula over the last twenty years was observed in 2007, 2017, 2018 and 2020. In the central part of the Crimean peninsula, which belongs to the climatic zone of Steppe Crimea, arid conditions had the greatest manifestation and distribution (zones with extreme and severe drought conditions are observed). Minor areas in the mountainous part of the Crimea also have signs of arid conditions, but for the most part the condition of vegetation is satisfactory in this area. In percentage terms, in 2007 VHI values of extreme and severe drought occupied 57% and 20% of the peninsula’s area accordingly, as well 10% and 29% in 2017, 7% and 22% in 2018 and 11% and 26% in 2020.
