Abstract
The work presents the results of the analysis of climatic changes of the lower stratiform clouds (Sc, St, Ns) over the territory of Siberia for the past 45 years (from 1969 to 2013), performed by the data of the 60 ground-based meteorological stations. The study of long-term changes of the amount and base height of low clouds were realized, using the curves of interannual variation, as well as linear trends and their intensity values.
