“…Besides the ice core studies, many investigations on environmental significance of speleothems isotopes were also carried out, and the isotopic evolutions from rainfall to drip water were observed across China, e.g., Luo et al (2013, 2014, Tan et al (2015), Zeng et al (2015). Luo et al (2008) and Peng and Li (2012) reviewed some progress on this subject; the main conclusion was that the drip water isotopes is jointly influenced by precipitation isotopic ratio and local environment, and the explanations of monsoon intensity and circulation effect were popular in speleothems isotope studies.…”

In the paper, the development of precipitation isotope observation networks in China was reviewed, and recent achievements in isoscape and environmental effect of precipitation stable isotopes were summarized; the hydrological process studies based on precipitation isotopes in China during recent decade were also reviewed. In past decades, the spatial and seasonal patterns of precipitation isotopes have been investigated nationwide, especially after the participation in GNIP (Global Network of Isotopes in Precipitation) and the establishment of CHNIP (Chinese Network of Isotopes in Precipitation), although long-term measurements are still limited; besides the nationwide network, a series of regional networks has been widely established across China. From the traditional manual drawing to the computer-aided mapping, and then to the simulation using isotope-equipped models, the productions of precipitation isoscape have been improved. The main factors controlling precipitation isotopes were summarized, and the potential significances of isotopes in climate proxies were mentioned. The recent studies about influence of raindrop sub-cloud secondary evaporation on isotopes were reviewed; based on the precipitation isotope and other parameters, the contribution of recycled moisture (evaporation and transpiration) in local precipitation can be estimated using three-or two-component mixing models. Finally, some prospects of precipitation isotope studies in China were presented.

“…Although the stalagmite  18 O record is widely regarded as a recorder of the local  18 O in precipitation (Zeng et al, 2015), it is not a direct recorder since the  18 O values may potentially be biased by local effects such as the "buffering effect" of soil water (Genty et al, 2014). Therefore, more records related to the past variation of the isotopic composition of precipitation are needed, especially D records since they can be directly compared with  18 O records.…”

“…The estimated uncertainty of ∼ 0.53 ‰ in the δ 18 O detailed in Sect. 2.1.2, along with difference in evaporation in the two caves, is likely to contribute to producing a negative δ 18 O. Cave-monitored data suggest evaporation may occur during dripping, and enhanced processes in a dry season could result in heavier drip water δ 18 O values (Zeng et al, 2015), especially in a wellventilated cave.…”

“…From them, LF6 with the lowest drip rate but highest variation has been selected, as it is considered to record climate information more efficiently. The lowest drip rate of LF6 from Liangfeng cave suggests fresh water is being mixed with delayed transit stored water at this drip site (Zeng et al, 2015) and may pro- (Duan et al, 2016).

Abstract. The 8.2 ka BP event could provide important information for predicting abrupt climate change in the future. Although published records show that the East Asian monsoon area responded to the 8.2 ka BP event, there is no high-resolution quantitative reconstructed climate record in this area. In this study, a reconstructed 10-year moving average annual rainfall record in southwest China during the 8.2 ka BP event is presented by comparing two highresolution stalagmite δ 18 O records from Dongge cave and Heshang cave. This decade-scale rainfall reconstruction is based on a central-scale model and is confirmed by interannual monitoring records, which show a significant positive correlation between the regional mean annual rainfall and the drip water annual average δ 18 O difference from two caves along the same monsoon moisture transport pathway from May 2011 to April 2014. Similar trends between the reconstructed rainfall and the stalagmite Mg / Ca record, another proxy of rainfall, during the 8.2 ka BP period further increase the confidence of the quantification of the rainfall record. The reconstructed record shows that the mean annual rainfall in southwest China during the central 8.2 ka BP event is less than that of present by ∼ 200 mm and decreased by ∼ 350 mm in ∼ 70 years experiencing an extreme drying period lasting for ∼ 50 years. Comparison of the reconstructed rainfall record in southwest China with Greenland ice core δ 18 O and δ 15 N records suggests that the reduced rainfall in southwest China during the 8.2 ka BP period was coupled with Greenland cooling with a possible response rate of 110 ± 30 mm • C −1 .
