“…Pausata et al (2011) used a climate model with an embedded oxygen-isotope model to simulate a Heinrich event and found that the variations of stalagmite δ 18 O values in southern China mainly reflected δ 18 O changes in the source vapor from the Indian Ocean rather than local precipitation amount. Liu et al (2015) also indicated that the stalagmite δ 18 O records during the Holocene from the East Asian summer monsoon region are essentially a signal of the isotopic composition of precipitation, which is largely determined by the upstream depletion mechanism over the Indian Ocean and the Indian monsoon region.…”

Abstract. In the Asian monsoon region, variations in the stable isotopic composition of speleothems have often been attributed to the "amount effect". However, an increasing number of studies suggest that the "amount effect" in local precipitation is insignificant or even non-existent. To explore this issue further, we examined the variability of daily stable isotopic composition (δ 18 O) in precipitation from September 2011 to November 2014 in Nanjing, eastern China. We found that intra-seasonal variations of δ 18 O during summer were not significantly correlated with local rainfall amount but could be linked to changes in the moisture source location and rainout processes in the source regions. Our findings suggest that the stable isotopes in summer precipitation could signal the location shift of precipitation source regions in the inter-tropical convergence zone (ITCZ) over the course of the monsoon season. As a result, changes in moisture source location and upstream rainout effect should be taken into account when interpreting the stable isotopic composition of speleothems in the Asian monsoon region. In addition, the temperature effect on isotopic variations in non-monsoonal precipitation should also be considered because precipitation in the non-monsoon season accounts for about half of its annual precipitation.

“…The northeastern Tibetan Plateau is located in a transitional zone between the EASM and ISM, and it is still not clear which of these monsoon systems (ISM or EASM) controls the precipitation over this area. 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.…”

“…While the Holocene variability of the precipitation associated with the East Asian summer monsoon (EASM) has been discussed in detail (e.g. Hu et al, 2008;Cai et al, 2010;Chen et al, 2015;Liu et al, 2015Liu et al, , 2017Chen et al, 2016), studies of temperature change on different temporal and spatial scales may provide deeper insights to past climate fluctuations and facilitate the prediction of future climate change. During the past few decades, various studies have reconstructed temper-ature change on different timescales in northern China, using for example pollen (e.g.…”

Abstract. Long-term, high-resolution temperature records which combine an unambiguous proxy and precise dating are rare in China. In addition, the societal implications of past temperature change on a regional scale have not been sufficiently assessed. Here, based on the modern relationship between chironomids and temperature, we use fossil chironomid assemblages in a precisely dated sediment core from Gonghai Lake to explore temperature variability during the past 4000 years in northern China. Subsequently, we address the possible regional societal implications of temperature change through a statistical analysis of the occurrence of wars. Our results show the following. (1) The mean annual temperature (TANN) was relatively high during 4000-2700 cal yr BP, decreased gradually during 2700-1270 cal yr BP and then fluctuated during the last 1270 years. (2) A cold event in the Period of Disunity, the Sui-Tang Warm Period (STWP), the Medieval Warm Period (MWP) and the Little Ice Age (LIA) can all be recognized in the paleotemperature record, as well as in many other temperature reconstructions in China. This suggests that our chironomidinferred temperature record for the Gonghai Lake region is representative. (3) Local wars in Shanxi Province, documented in the historical literature during the past 2700 years, are statistically significantly correlated with changes in temperature, and the relationship is a good example of the potential societal implications of temperature change on a regional scale.
