Changes in behaviors of East Asian monsoons and westerly jet axis since the last interglacial period were reconstructed using piston cores retrieved from the NW Pacific, and their relation with millennial-scale climatic changes in the North Atlantic were examined. The results suggest that changes in the position of westerly jet played a role of linking changes in East Asian monsoons with climatic changes in the Northern Atlantic. The results further suggest that the phase relation between changes in the North Atlantic climate and East Asian monsoons reversed between the last glacial and the Holocene. Ventilation rate of North Pacific Intermediate Water also varied in association with these changes during the last glacial period. The results of the last interglacial reconstruction further suggest that westerly jet axis and East Asian monsoon front may shift northward in response to the global warming.

利用从西北太平洋提取的活塞样，重建了末次间冰期以来东亚季风和西风急流轴的变化，并分析了它们与北大西洋千年尺度气候变化的关系。结果表明，西风急流位置的变化对东亚季风的变化与北方大西洋气候变化有联系作用。结果进一步表明，在末次冰期和全新世之间，北大西洋气候和东亚季风变化之间的相位关系发生了逆转。在末次冰期，北太平洋中层水的通气率也随这些变化而变化。末次间冰期重建的结果进一步表明，西风急流轴和东亚季风锋可能在全球变暖的影响下向北移动。
