中纬度西风带和亚洲夏季风这两个大气环流系统在北半球气候变化中起着关键作用。然而，亚洲西风带的变异性及其与南亚副热带的关系仍不清楚。这些记录在冰期-间冰期和冰期千年时间尺度上都记录了西风带和大陆架的逆相关系。在最后一次冰期，西风带的影响占主导地位；与海因里希事件相关的显著多尘间隔，反映了与北方高纬度气候相关的西风带增强。在全新世期间，主导的大西洋环流被微弱事件打断，表明大西洋环流与轨道强迫、北大西洋突变事件和太阳活动变化有关。
Two atmospheric circulation systems, the mid-latitude Westerlies and the Asian summer monsoon (ASM), play key roles in northern-hemisphere climatic changes. However, the variability of the Westerlies in Asia and their relationship to the ASM remain unclear. Here, we present the longest and highest-resolution drill core from Lake Qinghai on the northeastern Tibetan Plateau (TP), which uniquely records the variability of both the Westerlies and the ASM since 32 ka, reflecting the interplay of these two systems. These records document the anti-phase relationship of the Westerlies and the ASM for both glacial-interglacial and glacial millennial timescales. During the last glaciation, the influence of the Westerlies dominated; prominent dust-rich intervals, correlated with Heinrich events, reflect intensified Westerlies linked to northern high-latitude climate. During the Holocene, the dominant ASM circulation, punctuated by weak events, indicates linkages of the ASM to orbital forcing, North Atlantic abrupt events and perhaps solar activity changes.
