海洋氧同位素第二阶段(MIS)是研究东亚夏季风(EASM)和印度夏季风(ISM)两个亚洲季风子系统演化的理想时期,其环境和气候变化从末次盛冰期(LGM)前到末次冰消期。利用中国西南部三星洞石笋的875个稳定氧同位素比值和43个230 Th年龄,构建并解释了一个新的、可复制的、覆盖30.9- 9.7ka的亚洲夏季风(ASM)年代际分辨率记录。该洞穴的δ 18 O记录与中国其他洞穴的δ 18 O记录显示了相似的长期轨道主导趋势和与北方高纬度气候变化相关的同步千年尺度强、弱季风事件。有趣的是,三星δ 18 O和阿拉伯海记录显示22 ~ 17 ka的ISM减弱,而中国东部和中部的葫芦和青田记录显示20 ~ 17 ka的EASM增强。EASM和ISM之间的这种解耦可能是由于两个ASM子系统响应于与复杂的地理或陆地-海洋配置相关的内部反馈机制的不同敏感性。
Marine Oxygen Isotope Stage (MIS) 2, with its profound environmental and climatic changes from before the last glacial maximum (LGM) to the last deglaciation, is an ideal period for understanding the evolution of the East Asian summer monsoon (EASM) and Indian summer monsoon (ISM), two Asian monsoon sub-systems. With 875 stable oxygen isotope ratios and 43 230Th dates from stalagmites in Sanxing Cave, southwestern China, we construct and interpret a new, replicated, Asian summer monsoon (ASM) record covering 30.9–9.7 ka with decadal resolution. δ18O records from this site and other reported Chinese caves display similar long-term orbitally dominated trends and synchronous millennial-scale strong and weak monsoonal events associated with climate changes in high northern latitudes. Interestingly, Sanxing δ18O and Arabian Sea records show a weakening ISM from 22 to 17 ka, while the Hulu and Qingtian records from East and Central China express a 3-ka intensifying EASM from 20 to 17 ka. This decoupling between EASM and ISM may be due to different sensitivities of the two ASM sub-systems in response to internal feedback mechanisms associated with the complex geographical or land-ocean configurations.
