“…In order to verify the reliability of the δ 13 C record from Lake Mayinghai, we compared it with climatic records from the loess deposits of the Chinese Loess Plateau (CLP). In order to minimize the influence of local nonclimatic factors, the ages of paleosol development, which directly reflects humidity fluctuations, should be synthesized from across a wide area (Chen et al, ). A synthesis of paleosol development based on 310 dates from 77 sites on the CLP is shown in Figure b (Wang, Chen, et al, ), and a record of paleosol occurrence based on 335 dates from 75 sites in the dunefields of eastern China is shown in Figure c (Li et al, ).…”

The late Holocene is generally regarded as an interval of monsoon recession and decreased precipitation in North China. However, the extent to which this affected the status of lakes in North China is unclear. In the study, we analyzed multiple proxies (δ13C, magnetic susceptibility [χlf], and exogenous element concentrations) from Lake Mayinghai, an undisturbed alpine lake in North China. We also compared the results with previously published paleoenvironmental records from the Chinese Loess Plateau. We aimed to determine the extent of the influence of variations in the East Asian summer monsoon (EASM) on the status of Lake Mayinghai during the late Holocene. The results demonstrate that negative δ13C values at Lake Mayinghai correspond to high sedimentary tree pollen content and high reconstructed precipitation, indicating that variations in δ13C likely reflect variations in vegetation and the EASM in North China. A comparison of the δ13C record with other proxies from the same core reveals an abrupt change in the EASM at ~3 kyr before present (BP), which is also evident in other regional climate records from the Chinese Loess Plateau. The rapid decline in EASM intensity at ~3 kyr BP is also consistent with changes in the status of Lake Mayinghai, Lake Gonghai, Lake Ganhai, and Lake Daihai, in that these lakes underwent an abrupt retreat after 3 kyr BP, demonstrating that the rapid decline in EASM intensity at ~3 kyr BP had a large impact on lake evolution in North China.

“…Recent studies have suggested that the influence of the ISM has broadly extended into central and southern parts of eastern China during the past 2,000 years (Xu et al, ). These may result in complicated spatial monsoon patterns in continental China (J. Chen et al, , ). Because the limit of monsoonal influence may vary with relative strength of the EASM and ISM, it is possible that oceanic proxies (Li et al, ; Yamada et al, ) and Chinese continental records (Wang et al, ; Yi et al, ; Zheng et al, ) might better represent two alternate sources of precipitation, respectively.…”

The East Asian summer monsoon (EASM) is a key component of the Asian Monsoon system affecting regional precipitation in East Asia and thus human culture, society, and development. Despite this, decadal‐ to centennial‐scale EASM dynamics remain poorly understood over the last millennium. Here we used high‐resolution benthic microfossil proxies to reconstruct EASM variability for the last 1,000 years from a brackish lake in South Korea. We compared this EASM record with Asian Monsoon proxy records from East China (i.e., continental proxy) and East Asian coasts (i.e., oceanic setting), and identified four pervasive EASM strengthening events at 1250, 1450, 1550, and 1900 CE and their deviation, likely related to land‐ocean temperature gradients. Our results indicate that data from the oceanic setting under the direct influence of the Pacific High are important in understanding the EASM dynamics over the last millennium. It is also noteworthy that EASM variability shows striking similarity to changes in the Atlantic meridional overturning circulation, implying the causal relationship.

“…Precipitation in northern China has long been considered as an appropriate proxy for EASM (An et al ., ; Zhou et al ., ; Liu et al ., , ; Chen et al ., , ). In our study, the inferred decreased precipitation during the late deglaciation indicates a weakened EASM, and the persistent increasing (or decreasing) inferred precipitation in the early (or late) Holocene indicates an enhanced (or weakened) EASM (Fig.…”

“…Thus, the hypothesis of seasonality is not inconsistent with the upstream interpretation. These results support the conclusions that precipitation volume in northern China, rather than in southern China, is a reliable indicator of the strength of the EASM (Liu et al ., , ; Chen et al , , ), and the stalagmite records from southern China may not reflect the history of the EASM.…”

We investigate chironomid assemblages in a sediment core from Gonghai Lake, which is located on the East Asian summer monsoon (EASM) boundary in northern China, to quantify EASM variability during the past 13.5 ka BP. Six significantly different chironomid assemblage zones indicate that maximum precipitation and water depth occurred in the mid‐Holocene (8270–2700 cal a BP) and the minimum period was the past 1250 years. A modern dataset of 44 lakes near Gonghai Lake was sampled to calibrate the response of chironomid assemblages to precipitation. Our results demonstrate that mean annual precipitation is the most significant environmental variable influencing modern chironomid assemblages in this monsoonal region. Maximum EASM precipitation in the mid‐Holocene, indicated by chironomid assemblages in the monsoon fringe, contrasts with the early Holocene EASM maximum suggested by stalagmite δ18O data from southern China, but is consistent with other evidence. Our findings are compatible with the proposal that the stalagmite δ18O variations in southern China may not reliably reflect the evolution of EASM since the last deglaciation.
