东亚冬季风(EAWM)不仅在亚洲气候系统中起着重要的作用，而且还将冷空气从北半球的高纬度输送到南半球，起着连接极地和热带气候系统的作用。然而，由于缺乏适当的委托书记录，EAWM过去的变化迄今尚未明确确定。本文首先将湖光玛尔湖的泥沙捕集试验和百年来的沉积记录与东亚季风、西伯利亚高压(SH)和北极涛动(AO)的现代记录相比较，建立了EAWM的指数。其次，基于HML中的沉积硅藻组合，我们提供了过去14,500年来EAWM强度的连续记录。这一记录来自两种浮游硅藻物种相对丰度的波动。与EAWM强度的联系是通过引发湍流混合的高风速，这刺激了浮游物种颗粒Aulacoseira的生产力。过去14500年的硅藻记录表明，从全新世早期到晚期，EAWM由强到弱。这既与高纬度地区冬季温度的变化有关，也与热带地区的厄尔尼诺现象有关。我们的记录表明，在全新世，EAWM和东亚夏季风(EASM)在轨道时间尺度上是同相的而不是反相关的。在千年时间尺度上，末次冰期-全新世过渡期间，EAWM与EASM呈反位相。而在全新世早、中期，东亚夏季风与东亚夏季风的关系表现出空间差异。在中国北部，记录到明显的反相，而在中国南部，没有观察到反相。在全新世晚期，我们没有发现EAWM和EASM之间有任何明确的关系。我们还探讨了东亚季风和澳大利亚夏季风之间的联系。南半球夏季日照的ASM反位相是一个谜一般的例外，不能用经典日照理论解释。在全新世早期，东亚季风与澳大利亚夏季风(ASM)同相，这提供了第一个直接证据，支持了EAWM的强度至少部分地影响了ASM的强度的假设。
The East Asian winter monsoon (EAWM) not only plays an important role within the Asian climate system, but also carries cold air from the high northern latitudes across the Equator to the Southern Hemisphere, acting as a link between the polar and tropical climate systems. However, past changes of the EAWM have not been clearly established so far due to the lack of suitable proxy records. Here, we at first establish an index of the EAWM by comparing the results of a sediment trap experiment and 100-year sedimentary record from Huguang Maar Lake (HML) with modern records of the EAWM, Siberian High (SH) and Arctic Oscillation (AO). Secondly, we present a continuous record of the strength of the EAWM for the past 14,500 years based on sedimentary diatom assemblages in HML. The record is derived from fluctuations in the relative abundance of two planktonic diatom species. The link with the EAWM intensity is through high wind speeds inducing turbulent mixing, which stimulates the productivity of the meroplanktonic species Aulacoseira granulata. The diatom record of the past 14,500 years shows that the EAWM shifted from strong to weak from the early to late Holocene. This linked to both changes in winter temperature at high-latitudes and in El Niño conditions in the tropics. Our record shows that the EAWM and East Asian summer monsoon (EASM) as recorded in stalagmites, were in-phase instead of anti-correlated on orbital time scales during the Holocene. On a millennial time scales, the EAWM was anti-phase with the EASM during the Last Glacial–Holocene transition. However, during the early–middle Holocene the relationship between the EAWM and EASM shows spatial variations. In northern China, the records show significant anti-phase, but in southern China the anti-phase was not observed. During the late Holocene, we did not find any clear relationship between the EAWM and EASM. We also explored the link between the EAWM and the Australian summer monsoon (ASM). Anti-phase of the ASM with summer insolation in the Southern Hemisphere is an enigmatic exception that cannot be explained by the classic theory of insolation. During early Holocene the EAWM was in-phase with the Australian summer monsoon (ASM), which provides the first direct evidence to support the hypothesis that the intensity of the EAWM affected, at least in part, the strength of the ASM.
