The cooling by 5°C from 21 ka to 12.8 ka implies the equatorward shift of the subarctic boundary in the northwestern Pacific by ~2.8° in latitude. This shift was a result of the stronger summer Okhotsk High. The Okhotsk High was likely enhanced by the combined effects of El Niņo-like conditions in the tropical Pacific and the heating of the land surface of northeastern Siberia.
