Forecast of Changes in Air Temperatures and Heat Indices in the Sevastopol Region in the 21st Century and Their Impacts on Viticulture

Climate is a limiting factor in viticulture, as it defines favorable areas, grape cultivars, and agrotechnical activities. In the Sevastopol region, viticulture main promising agricultural branch. Using outputs of regional climate models from CORDEX project, projections agroclimatic conditions region for two future periods (2021–2045 2046–2070) under representative concentration pathways (RCP4.5 RCP8.5) were obtained. The results our study show trend temperature indices rise (average growing season temperature, effective heat sum, Winkler Huglin indices) region’s transition to higher classes, especially during second period (2046–2070). However, despite indices, will remain suitable grapes cultivars with all ripening periods.
