The question of how forest ecosystems influences climate parameters is of growing scientific interest. This work analyzes two approaches to the study of interaction between Siberian forests and the atmosphere. Based on the analysis results, we suggest that a four-year cycle in precipitation over forest areas can be caused by tree transpiration. This finding is to help understanding similar cyclic patterns in meteorological data in other regions with large forest ecosystems. The results can be useful for specialists dealing with problems of biosphere-atmospheric interaction.
Ageev et al. (2026) studied this question.
