Abstract

The results of research work conducted at the Caspian Federal Agricultural Research Center, Russian Academy of Sciences, in Astrakhan oblast in 2024 are reported. The aim of this work was to identify climate changes and to determine their trend in the region. The quantitative climate indices were calculated based on the datasets containing average monthly air temperatures and monthly sums of precipitation for the period of 1978–2023. The evaporative capacity was calculated according to the methods of A.I. Budagovskii, G.T. Selyaninov, and N.A. Shumova. As a result of this study, a negative trend in the Selyaninov hydrothermal coefficient and the Vysotskii–Ivanov moisture coefficient was revealed. The analysis of the meteorological data for 46 years showed that the region is experiencing actual climate change leading to arid warming.
