“…Indeed, the oxygen isotope concentration of stalagmites from Fukugaguchi Cave in North Central Japan had a significant negative correlation with rainfall amount in winter. The rainfall in this area mainly occurs in wintertime and is caused by winter wind [50]. From this point of view, when the source of water vapor is constant, continuous heavy monsoon rainfall will lead to a gradual negative bias of oxygen isotopes in the north China monsoon marginal area, which also explains the negative correlation between oxygen isotope concentration and rainfall amount in stalagmites in this area [15][16][17]48].…”

Based on stable hydrogen and oxygen isotope data (δ 18 O, δD) and meteorological observation data for complete hydrological annual precipitation from 2016 to 2017 in the monsoon marginal region of northern China (Fengxiang and Ningwu), the isotopic characteristics of precipitation and the sources of water vapor in these two regions combined were studied. The results showed that δ 18 O and δD values in the wet season (June through September) were higher than in the dry season (October to May of the following year) in Fengxiang and Ningwu. The intercept and slope of the meteoric water line in the two regions were somewhat low, revealing that the water vapor in the rainfall comes mainly from the tropical ocean. On a synoptic scale, significantly positive correlations among dry season precipitation, δ 18 O, and temperature manifested temperature effects, but in the wet season, the temperature effect was not significant. On a monthly scale, a relationship did not exist between the change in trend of the average value of monthly weighted δ 18 O in precipitation and the average temperature change value in the two regions. However, in the wet season, significantly negative relationships can be found between the average monthly weighted δ 18 O in precipitation and rainfall amount, which indicated a remarkable rainout effect. Further investigation revealed that continuous precipitation made the values of δ 18 O and δD more negative under the same source of water vapor (the rainout effect). Because the annual rainfall in the monsoon marginal region of Northern China is mainly made up of monsoon rainfall, the oxygen isotope index of geological and biological records, such as stalagmites and tree rings, which inherit meteoric water isotope information, can be used to reconstruct past rainfall changes in northern China.

The Holocene stalagmite FG01 collected at the Fukugaguchi Cave in Itoigawa, central Japan provides a unique high-resolution record of the East Asian winter monsoon. Because of the climate conditions on the Japan Sea side of the Japanese islands, the volume of precipitation during the winter is strongly reflected in the stalagmite δ 18 O signal. Examination of the carbon isotopes and the Mg/Ca ratio of FG01 provided additional information on the Holocene climate in Itoigawa, which is characterized by two different modes separated at 6.4 ka. Dripwater composition and the correlation between the δ 13 C and Mg/Ca data of FG01 indicate the importance of prior calcite precipitation (PCP), a process that selectively eliminated 12 C and calcium ions from infiltrating water from CO 2 degassing and calcite precipitation. In an earlier period (10.0-6.4 ka), an increase in soil pCO 2 associated with warming and wetting climate trends was a critical factor that enhanced PCP, and resulted in an increasing trend in the Mg/Ca and δ 13 C data and a negative correlation between the δ 13 C and δ 18 O profiles. A distinct peak in the δ 13 C age profile at 6.8 ka could be a response to an increase of approximately 10% in C4 plants in the recharge area. At 6.4 ka, the climate mode changed to another, and correlation between δ 18 O and δ 13 C became positive. In addition, a millennial-scale variation in δ 18 O and pulsed changes in δ 13 C and Mg/Ca became distinct. Assuming that δ 18 O and PCP were controlled by moisture in the later period, the volume of precipitation was high during 6.0-5.2, 4.4-4.0, and 3.0-2.0 ka. In contrast, the driest interval in Itoigawa was during 0.2-0.4 ka, and broadly corresponds to the Little Ice Age.

“…The oxygen stable isotope composition (δ 18 O) of stalagmites reflects that of rainwater, which enables the use of such data as a paleomonsoon proxy (e.g., Wang et al, 2001Wang et al, , 2005Wang et al, , 2008Yuan et al, 2004;Cheng et al, 2009;Sone et al, 2013). Stalagmite carbon stable isotope compositions (δ 13 C) can be used as proxies for veg-tionally been used to reconstruct atmospheric and hydrologic circulation patterns, identify scavenging processes, determine co-precipitation, and define redox reactions in aqueous phases (e.g., Johannesson et al, 1995;Greaves et al, 1999;Dia et al, 2000;Playà et al, 2007).…”
