Intraannual and interannual changes in clouds in Ufa

The study of cloud cover and its characteristics (quantity and forms) is of practical interest, especially for large cities. Cloud cover, having a dual effect (albedo and greenhouse), is an important factor in the formation of the thermal regime in the conditions of global climate change. This article presents the results of the analysis of daily, annual and long-termchanges in thecloudcover regime in thecity of Ufa (Republic of Bashkortostan). Urgent data from long-term observations of clouds (1966–2020) were used for the analysis. The main patterns of the daily course of clouds in the months of the cold and warm period of the year are revealed. The long-term dynamics of cloud cover has shown that its number has a significant upward trend.
