It is known that changes in atmospheric pressure affect the water level in observation wells, wells, the flow rate of springs and the supply of groundwater to watercourses. The mechanisms of this phenomenon have not yet been fully disclosed. In the journal "Hydrosphere. Hazard processes and phenomena," (volume 3, issue 3) an article by a team of authors has been published, in which a hypothesis has been put forward about the presence of a baric effect of atmospheric influence on the moisture capacity of organogenic horizons of tundra soils. According to the proposed assumption, with a decrease in atmospheric pressure, the capillary moisture capacity of tundra soils containing an aquifer increases, its water output decreases, and this lowers the water level in the pits and reduces the permafrost runoff. With a sharp increase in pressure and a reduction in the moisture capacity of soils, the retained moisture is discharged, which, taking into account the current supply of the horizon with meltwater, leads to a jump in the permafrost and restoration of river runoff. The interpretation of the data of short-term field observations proposed in the article is questionable. Considering that the described effect is still poorly understood and a comprehensive discussion is needed to understand it, this article presents considerations on the debatable issues raised about the role of atmospheric pressure in the formation of river runoff.
