“…Model-proxy comparison therefore suggested the climatic optimum on the northeastern Tibetan Plateau lagged the peak summer insolation by ~3.5 ka. It is therefore suggested that ostracod δ 18 O proxy records are not reasonable for measuring the amount of precipitation on the northeastern Tibetan Plateau, arguing the conclusion drawn by others (Lister et al 1991;Liu et al 2007;Wang et al 2011;An et al 2012). …”

“…A relatively dry climate during the early Holocene is also indicated by the significantly low lake levels of Qinghai Lake during this period (Liu et al 2013Wang et al 2014b). However, ostracod δ 18 O records from Qinghai Lake indicate a drying trend in this region throughout the Holocene, closely following Northern Hemisphere summer insolation (Liu et al 2007;Wang et al 2011;An et al 2012). This drying trend is further supported by hydrogen isotope records from Qinghai Lake (Thomas et al 2016) and Genggahai Lake (Rao et al 2016).…”

“…A number of palynological studies have concluded the EASM to have been the dominant factor influencing precipitation changes during the Holocene Liu et al 2015a;, and the strength of the EASM is believed to have been suppressed by the continental ice sheets during the early Holocene (Chen et al 2015a, b). Other studies, however, based on stable hydrogen and oxygen isotope records (Liu et al 2007;Rao et al 2016;Thomas et al 2016), suggest that the precipitation over this area has been governed during the Holocene by the ISM.…”

“…18 O values of core sediments in Qinghai Lake, which receive the signal from precipitation δ 18 O, are traditionally regarded as a proxy that can reflect the amount of precipitation over this region (Lister et al 1991;Liu et al 2007;Wang et al 2011;An et al 2012). However, observed precipitation δ…”

a b s t r a c t a r t i c l e i n f oThe numerical meta-analysis of 92 proxy records (72 sites) of moisture and/or temperature change confirms earlier findings that the dominant trends of climatic evolution in monsoonal central Asia since the Last Glacial roughly parallel changes in Northern Hemisphere summer insolation, i.e. the period following the Last Glacial Maximum was characterized by dry and cold conditions until 15 cal. kyr BP, followed by a warm, wet period coincident with the Bølling/Allerød warm period and terminated by a cold, dry reversal during the Younger Dryas period. After an abrupt increase at the start of the Holocene, warm and wet conditions prevailed until ca. 4 cal. kyr BP when moisture levels and temperatures started to decrease. Ordination of moisture records reveals strong spatial heterogeneity in moisture evolution during the last 10 cal. kyr. The Indian Summer Monsoon (ISM) areas (northern India, Tibetan Plateau and southwest China) exhibit maximum wet conditions during the early Holocene, while many records from the area of the East Asian Summer Monsoon indicate relatively dry conditions, especially in north-central China where the maximum moisture levels occurred during the mid-Holocene. We assign such phenomena to strengthened Hadley Circulation centered over the Tibetan Plateau during the early Holocene which resulted in subsidence in the East Asian monsoonal regions leading to relatively dry conditions. Our observations of the asynchronous nature of the two Asian monsoon subsystems on millennial time scales have also been observed on annual time-scales as well as implied through the spatial analysis of vertical air motion patterns after strong ascending airflows over the Tibetan Plateau area that were calculated from NCEP/NCAR reanalysis data for the last 30 years. Analogous with the early Holocene, the enhancement of the ISM in a 'future warming world' will result in an increase in the asynchronous nature of the monsoon subsystems; this trend is already observed in the meteorological data from the last 15 years.

Knowledge of the paleoclimatic record of the northeastern Tibetan Plateau (NETP) can potentially improve our understanding of the evolution of the Asian summer monsoon (ASM). However, the history of climate change and inferred spatial extent of the ASM on the NETP since the last deglaciation remain unclear. Here, we use several environmental proxies from the sediments of Hala Lake (beyond the modern limit of ASM), including chironomids, loss‐on‐ignition, grain size and element data, to explore the climatic history of the NETP and the northern boundary of the ASM since the last deglaciation. The results document a series of climatic events during the deglaciation, including Heinrich Event 1, the Bølling–Allerød interstadial and the Younger Dryas event. The records also reveal the timing of the megathermal and precipitation maximum, the lake‐level maximum, and strongest chemical weathering, which occurred during ~10–7 ka. The inferred precipitation maximum during the early Holocene in the Hala Lake basin, which can be verified by the simulated precipitation change, is consistent with that in typical Indian summer monsoon (ISM) regions, suggesting that the ISM has penetrated into Hala Lake basin at that time. The monsoon‐dominated climate in the Hala Lake basin during the early Holocene and the westerlies‐dominated climate in the arid central Asia indicate that the maximum areal extent of the ASM on the NETP since the last deglaciation lay to the northwest of Hala Lake basin. In combination with other published records, the northernmost boundary of the ASM over China since the last deglaciation has been tentatively delineated, to shed some lights on this long‐standing debate.
