Abstract
Interest in understanding the influence of forest ecosystems on the formation of climate parameters continues to grow. This paper examines two approaches to the study of interaction between Siberian forests and the atmosphere. Based on the results of the analysis, it was suggested that the formation of a 4-year cycle in precipitation over forest areas may occur with the participation of tree transpiration. This finding will help us to understand the emergence of similar cyclical patterns in meteorological data from other regions with extensive forest ecosystems. The results may be useful for specialists dealing with problems of biosphere-atmospheric interaction.
