A similar to 2200-year moisture history of the southern Altai Mountains (i.e., Chinese Altai) was established based on peat delta C-13(celluose) data obtained at Yushenkule (YSKL) Peat. Generally speaking, the moisture record from YSKL Peat exhibits a "cool-wet" DACP (Dark Age Cold Period from similar to 500 to similar to 800 CE), a "warm-dry" MWP (Medieval Warm Period from similar to 800 to similar to 1200 CE), a "cool-wet" LIA (Little Ice Age from similar to 1200 to similar to 1900 CE), and a "warm-dry" CWP (Current Warm Period since similar to 1900 CE). But, RWP (Roman Warm Period from prior to similar to 100 CE to similar to 500 CE) is an exception (i.e., "warm-wet"). If the heat-water combinations within those major temperature-change events are further examined, the "warm-dry/cool-wet" generalization collapses. The comparisons between the variations in the peat delta C-13(celluose)-based moisture obtained from YSKL Peat and the variations of reconstructed climatic variables in the referenced sequences suggest that the moisture variations in the Altai Mountains have been basically controlled by the precipitation that was primarily modulated by the NAO variations.
