Abstract

The change tendency in the duration of the frost-free period in the territory of Georgia is analysed by comparing the last 16 years of data (2007-2022) with the similar one of the previous periods (1951-1965). The early, average and late values of the last spring and first autumn frost dates in the study regions were evaluated. It was revealed that in the period 2007-2022 compared to 1951-1965, the average values of frosts shifted earlier for the last spring frost and later for the first autumn frost, which led to frost-free periods increasing and, accordingly, the length of the vegetation period. The map depicting the duration of increased frost-free periods is presented, the trend of increasing frost-free periods under climate change is revealed, and the dependence of these periods on the North Atlantic Oscillation is also fixed.
