Abstract
The analysis of the dynamics of the moisture regime in the Central forest-steppe was performed using the hydrothermal coefficient of G.T. Selyaninov (HTC) calculated based on the data of meteorological stations No. 34123 “Voronezh”, No. 27930 “Lipetsk”, No. 34214 “Belgorod”, No. 34009 “Kursk”. The frequency of severe droughts (HTCm-s 0.3-0.6) at the named meteorological stations over the past 85 years (1940-2024) is from 3 to 6, moderate droughts (HTCm-s 0.6-0.8) – from 3 at the meteorological station “Kursk” to 14 at the meteorological station “Belgorod”. A strong contribution of precipitation amounts to the HTC for the period May-September values was revealed, the relationship is high (r = 0.91), the contribution of air temperatures is less, the relationship is significant (r = 0.69). The dynamics of the hydrothermal coefficient values for the period May–September shows a general decrease in the level of moisture supply in the Central Forest-Steppe territory, especially in the last thirty years. A significant increase in average air temperatures is observed at all meteorological stations. The distribution of precipitation amounts by half-years showed a decrease in both the warm and cold periods at the meteorological stations “Belgorod” and “Lipetsk” and a slight increase in the cold period at the meteorological stations “Voronezh” and “Kursk”. The average HTC values for the observation period at the named meteorological stations were: “Voronezh” – 1.06, “Lipetsk” – 1.07, “Belgorod” – 1.03, “Kursk” – 1.25. In the last thirty years: “Voronezh” – 1.03, “Lipetsk” – 0.96, “Belgorod” – 0.94, “Kursk” – 1.22.
