亚洲季风（AM）气候研究的一个巨大障碍是普遍缺乏对大规模季风变化的长期观测。在这里，我们基于树木年轮年表网络（1600-1991），对中国和蒙古（CM）夏季主要水分模式的时间变化进行了充分验证的重建。重建揭示了过去四个世纪以来大规模AM的重大变化，这与有记录的时期中国历史上的戏剧性事件相吻合。这些事件包括明朝的灭亡（公元1644年）和中国大跃进期间的灾难性饥荒（1958-1961）。总体而言，重建的 AM 强度与过去四个世纪的北半球温度代理非常吻合。然而，这种关系在近几十年来已经破裂，增加了季风动力的主要驱动力本质上已从自然转向人为的可能性。引文：Li, J., et al.

A great impediment of Asian monsoon (AM) climate studies is the general lack of long-term observations of large-scale monsoon variability. Here we present a well-verified reconstruction of temporal changes in the dominant summer moisture pattern over China and Mongolia (CM), based on a network of tree-ring chronologies (1600-1991). The reconstruction reveals significant changes in the large-scale AM over the past four centuries, which coincide with dramatic episodes in Chinese history over the period of record. These episodes include the fall of the Ming Dynasty (AD 1644) and the catastrophic famine during China's Great Leap Forward (1958-1961). Overall, the reconstructed AM strength corresponds well with Northern Hemisphere temperature proxies over the past four centuries. Yet, this relationship has broken down in recent decades, raising the possibility that the major driving force of monsoon dynamics has shifted from natural to anthropogenic in nature.
