Abstract
The features of the spatio-temporal changes in the absolute minimum air temperatures in the basin of Lake Sevan are considered. The data of daily observations of the extremes of the minimum temperatures of the surface air layer at seven meteorological stations for the period 1935–2019 were used as the initial material. It was found that at all meteorological stations currently operating on the territory of the Lake Sevan basin, a tendency of an increase in the absolute minimum temperatures of both monthly and annual values is mainly observed. Moreover, the smallest changes are observed in the summer months. It was also found that in the Lake Sevan basin, the annual number of days with a temperature of –20°C and below tends to decrease. This natural dynamics testifies to the fact that in the studied area in terms of temperatures, a softening of winters is recorded. As a result, it turns out that on the territory of the Lake Sevan basin it is possible to grow more thermophilic agricultural crops that have not been grown before.
