摘要：

This paper analyzes the surface air temperature data for the city of Sukhum for the period 1961-2022. These values are presented as time series of average annual temperatures. As a result, we get 2 main components: trend, spectrum (including cycles). In general, the average annual temperature has a predominantly positive trend, i. e. over the entire period the temperature has increased by 1.31 degrees, which may occur against the background of global warming. Accordingly, another task of the current work was to identify cyclic components and determine their physical nature. A quasi-two-year, 5-6-year, solar activity cycle and a multi-year cycle (2-3 decades) are observed.
