A continuous 7.44 m lake core was successfully drilled at Gun Nuur Lake, northern Mongolia, and analyses on environment magnetic parameters, organic matter content and organic δ~(13)C were conducted in an attempt to retrieve the Holocene chronosequence of climatic changes based on 6 AMS ~(14)C dates. We found that the Holocene climate in northern Mongolia has been alternating between cold (or cool)/wet conditions and warm/arid conditions, and also punctuated with a series of abrupt climate shifts. The abrupt climate shifts occurred around 1750, 2800, 4000, 5200, 7200, and 9200 aBP (~(14)C age), being chronologically correlative to those abrupt climatic events recorded in the highlatitude North Atlantic Ocean. The correlation indicates that the climatic changes in northern Mongolia were linked with those in the North Atlantic Ocean probably via the North Atlantic Oscillation-affected westerly winds. The strength and position of westerly winds might have modulated the Siberian-Mongolian high pressure sys A continuous 7.44 m lake core was successfully drilled at Gun Nuur Lake, northern Mongolia, and analyzes on environment magnetic parameters, organic matter content and organic δ ~ (13) C were conducted in an attempt to retrieve the Holocene chronosequence of climatic changes based on 6 AMS ~ (14) C dates.
