摘要: 基于贵州雾露洞石笋(WU3)9个230Th年龄和1 317个氧同位素数据,建立了39.1~29.2 kaBP平均分辨率为10 a的亚洲夏季风强度变化序列,揭示了深海氧同位素3阶段(MIS3)晚期千年-百年尺度亚洲夏季风演变过程。雾露洞和葫芦洞石笋δ18O记录在重叠时段具有很好的重现性,表明石笋δ18O记录可反映大尺度区域性季风环流特征。雾露洞记录与格陵兰冰心δ18O记录对比表明,千年-百年尺度季风突变事件频率与高北纬气温呈现较好的相似性,表明低纬季风与北极气候存在遥相关。在事件结构及转型模式上,雾露洞记录与南极EDML冰心δ18O在反相位关系下呈现出细节上的一致性,反映亚洲季风可能受到南半球气候因素的影响,其机制可能是南大洋潜热释放通过越赤道气流影响了亚洲季风强度的变化。亚洲季风和南极温度的反相位关系进一步证实南北半球气候在千年-百年尺度上响应"see-saw"模式。Abstract: A 10-year resolution oxygen isotope record from the Wulu Cave, based on 9 precise 230Th dates and 1 317 oxygen isotope measurements, provides a detailed history of the Asian Monsoon from 39.1 kaBP to 29.2 kaBP, spanning the marine isotope stage 3.The fairly good replication of δ18O signal between the Wulu Cave and the Hulu Cave during the same growth periods indicates that the δ18O signals well recorded climatic changes and the changes in the monsoon system were are similar over a large area of China. The comparison between the Wulu Cave and Greenland ice core record indicates that the frequency of centennial and millennial scale monsoon events match well with the temperature in North high latitude. Our monsoon characteristics more closely resemble, but are anticorrelated with the features in the Antarctic record, indicating some sort of link to the climate in the high southern latitudes. It means that the Asian monsoon intensity may be impacted by cross-equatorial flow driven by the low temperature of the southern ocean and the change in the vapor heat release. It is believed that the low-latitude monsoon and Antarctic temperature responded to each other in a "see-saw" mode on centennial-millennial scales.
