The article presents the results of a comparative analysis of long-term changes in temperature anomalies on the territory of the city of Petropavlovsk, Republic of Kazakhstan. The analysis was carried out on the basis of long-term data for 85 years – from 1935 to 2020.According to the results of the analysis, it was revealed that 11 months underwent changes in the anomalies towards an increase in the frequency of positive sign, except for July, in which an increase in the frequency of negative anomalies was recorded by 4, 6% in recent decades.
