Abstract The aim of the research was to analyze the changes in weather conditions for the period 1961–2020 according to the Uman meteorological station. To achieve this goal, an analysis of changes in air temperature and precipitation over two multi-year cycles (1961–1990 and 1991–2020) was conducted, which allowed to predict the possible consequences for agricultural production. As a result of research it was found that the amount of precipitation for the seasons 1961–1990 and 1991–2020 decreased in winter, spring and summer by 75 mm, but increased by 28 mm in autumn, so in the context of the year their total deficit was 47 mm. The distribution of precipitation by the seasons 1961–1990 and 1991–2020 has changed: winter – from 22 to 19.1 %; spring - from 22.4 to 22 %; summer - from 36.8 to 33.8 %; autumn – from 18.8 to 25.1 % of their annual number. The interseasonal amplitude of temperature fluctuations in 1991-2020 decreased by 0.1 and 0.2 C in the autumn-winter and winter-spring periods and by 0.6 and 1 °C increased in the spring-summer and summer-autumn periods compared to with indicators in 1961–1990. The data obtained show a sharp rise in temperature over the past 30 months for agricultural formations of various forms of ownership in Cherkasy region.
