Abstract
Interdecadal cyclicity of tree ring increment on the upper and lower limits of the forest in mountainous regions of Inner Asia was estimated. This data and records from Teeli meteorological station were used to reconstruct June and July temperatures since 1715 and May and June water discharge of the Buyant River (Mongolia) since 1474. Verification of the detected cycles using the instrumental hydrometeorological data allowed concluding that 21–45-year cycles of tree ring growth had been caused by climtic oscillations.
