Impact of climate change on the freezing characteristic parameters in the Samtskhe-Javakheti region. Naili Kapanadze, Marika Tatishvili, Irine Mkurnalidze, Ana Palavandishvili/Transactions IHM, GTU. -2024. -vol.135. pp. 54-58 - Georg, Summ. Georg., Eng. According to the 2007-2022 weather stations data in the Samtskhe-Javakheti region, the intensity distribution of frosts of different power has been studied. The early, average and late values of the dates of the last spring and the first autumn frost in the research period have been established. In 2007-2022 period compared to the 1951-1965 one, the shift in the average values of freezing has been revealed for the last spring frosts 1-14 days earlier, and for the first autumn frosts 7-10 days later, which increased the duration of frost-free periods and, accordingly, the duration of the vegetation period by 11- 21 days, which corresponds to 10-17%. An exception is Akhaltsikhe, where the reduction of frost-free periods by 15 (9%) days will be observed. The trend of increasing frost-free periods and the dependence of these periods on the Arctic Oscillation has been revealed.
