“…To test the strength of spatial representation of our reconstruction, we further compared it with several tree-ring-based reconstructions farther from our study area, including an annual previous August-current July precipitation reconstruction for the Zhangye area (HYG) (Zhang et al, 2011b), a January-June moisture balance reconstruction for the eastern Qaidam Basin (Yin et al, 2016b) , and an annual (previous July-current June) precipitation reconstruction for the north-eastern Tibetan Plateau (Yang et al, 2014). In addition, the May-September historical document-based dry-wet index series for northern China (Zheng et al, 2006) and in the stalagmite oxygen stable isotope record from the Huangye Cave in central China (Tan et al, 2010) were also included ( gure 6h and 6i).…”

“…In the 10-30 yr scales, precipitation displayed more signi cant effects on the social vicissitudes (Yin et al, 2016a). For example, in the late 3rd century, persistent drought occurred in Northwest China (He et al, 2013;Liu et al, 2009;Wang et al, 2019;Yang et al, 2014;Yin et al, 2016b) , more than 100000 people in Gansu Province migrated to Sichuan Province due to years of famine, which led to the outbreak of war and the subsequent establishment of the Cheng Han regime (Compile Group of Chinese Military History, 2002). Too little precipitation can trigger pasture deterioration and nomadic migrations, especially for people in northern and north-western China (Pei and Zhang, 2014).…”

Moisture conditions, especially those that occur as multi-decadal anomalies, have profound impacts on society, especially in arid and semi-arid regions. However, the lack of high-resolution climatic data for the rst millennium CE greatly limits our understanding how moisture variations have in uenced history.Here, we present an 1882-year (134-2015 CE) tree-ring chronology developed from the Qilian juniper (Juniperus przewalskii Kom.) growing in the western Qilian Mountains, northwest China. The tree-ring index correlates signi cantly with the May-June self-calibrating Palmer Drought Severity Index (sc-PDSI)and could therefore be used to reconstruct May-June moisture variations since 241 CE. The reconstruction re ects moisture conditions at the annual to multi-decadal time scales over the past two millennia. During the period from the 3rd to 8th centuries, there were prominent interdecadal uctuations, with the 3rd century and the late 5th century being the wettest and driest periods in the reconstruction, respectively. The transition from the wet 3rd century to the dry 5th century corresponded with key events in Chinese history, namely the demise of the Western Jin Dynasty and the chaotic Southern and Northern Dynasties, as well as the fall of the ancient Loulan Kingdom in eastern Xinjiang. Thus, our reconstruction provides new evidence for the close linkage between abnormal climate conditions and social changes in ancient times.

“…The possible solar contribution of the Gleissberg century cycle to climate changes over at least the last millennium has been reported from the North Atlantic region (Moffa-Sánchez et al, 2014;Ogurtsov et al, 2002aOgurtsov et al, , b, 2015. In arid Central Asia, several records documented the solar fingerprint by the evidence of ∼ 200-year periodicity between the proxy data and solar activity time series (Zhao et al, 2009;Yin et al, 2016), and sediment records from Lake Toson and Lake Manas exhibited periodicities of 93 years and 70 to 100 years respectively through the spectral and wavelet analysis, which may be linked with the Gleissberg solar cycle (Ling et al, 2018;Song et al, 2015). However, still, rare records in ACA documented the good relationship between the effective humidity changes and the fluctuations of the Gleissberg cycle.…”

Abstract. Hydroclimate changes have exerted a significant influence on the historical trajectory of ancient civilizations in arid Central Asia where the central routes of the Silk Road have been hosted. However, the climate changes on different timescales and their possible forcing mechanisms over the last millennium remain unclear due to low-resolution records. Here, we provide a continuous high-resolution humidity history in arid Central Asia over the past millennium based on the ∼1.8-year high-resolution multiproxy records with good chronological control from Lake Dalongchi in the central Tian Shan. Generally, the climate was dry during the Medieval Warm Period (MWP) and Current Warm Period (CWP) and wet during the Little Ice Age (LIA), which could be attributed to the influence of the North Atlantic Oscillation (NAO) and the Atlantic Multidecadal Oscillation (AMO). Furthermore, we find that the humidity oscillation was dramatic and unstable at multidecadal to century scales. Especially within the LIA, four wet episodes and three dry periods occurred. The continuous wavelet analysis and wavelet coherence show that the humidity oscillation is modulated by the Gleissberg cycle at the century scale and by the quasi-regular period of El Niño–Southern Oscillation (ENSO) at the multidecadal scale. Our findings suggest that the effect of the solar cycle and the quasi-regular period of ENSO should be seriously evaluated for hydroclimate predictions and climate simulations in arid Central Asia in the future.

“…Our analysis shows that precipitation reconstruction based on tree-ring data in the region with an API between 200 and 600 mm is not only influenced by the Asian summer monsoon [ 45 ], which generally contains a 2.5- to 2.8-year quasi-biennial oscillation (QBO characteristic) according to the characteristics of the Asian summer monsoon variations [ 49 ], but also influenced by other factors such as the Pacific Decadal Oscillation, El Niño-Southern Oscillation (ENSO) and solar activity. Since these sequences generally contain 3- to 5-year, 7- to 8-year, 11-year and centennial periodicities [ 12 , 50 ], synthetic influences by both ENSO and solar activity are also likely [ 45 ]. In addition, large-scale land–sea coupling is also reflected in the TRW records in this region, as they show very high correlation with the sea-surface temperatures of the tropical Indian Ocean, the equatorial Pacific Ocean, the East China Sea and the Sea of Japan [ 43 ], indicating that the sea-surface temperature changes surrounding China have a direct impact on the strength of the Asian summer monsoon, thereby affecting the changes in precipitation in the area.…”

The numerous temperature and precipitation reconstructions in China based on tree-ring-width data have played significant roles in furthering the understanding of past climate changes. However, the geographical variability in the responses of trees to climate variations in China remains largely undetermined. Here, we describe an important spatial boundary in the response of trees to climate variations, namely the 600-mm annual precipitation isoline. We found that, to the north of this line, tree-ring widths are usually positively correlated with precipitation and negatively correlated with growing-season temperature. To the south of this line, the tree-ring widths respond positively to temperature, and winter half-year temperatures are the main reconstructed parameters, especially on the third topographical step of China. We also found that precipitation reconstructions based on tree-ring data and the Palmer Drought Severity Index almost exclusively fall in the region of the 200- to 600-mm annual precipitation isolines, not other regions. Our findings indicate that, when using multiple tree-ring-width chronologies for large-scale past climate reconstructions, the climatic signal of each tree-ring-width series should be carefully considered.
