Multi-scale variability of the Asian monsoon recorded in an annually-banded stalagmite during the Neoglacial from Qixing Cave, Southwestern China

Contrasting Patterns in Abrupt Asian Summer Monsoon Changes in the Last Glacial Period and the Holocene

“…The yellow area represents the Qinghai‐Tibetan Plateau. The numbers indicate locations for the (1) Kulishu (39°41′N, 115°39′E, Ma et al, ), (2) Qingtian (31°20′N, 110°22′E, this study), (3) Sanbao (31°40′N, 110°26′E, Zhao et al, ), (4) Tian'e (31°43′N, 110°38′E, this study), (5) Heshang (30°27′N, 110°25′E, Liu, Henderson, et al, ), (6) Hulu (32°30′N, 119°10′E, Wang et al, ), (7) Wulu (26°03´N, 105°05′E, this study), (8) Dashibao (26°05′N, 105°03′E, Zhao et al, ), (9) Yamen (25°29′N, 107°54′E, Yang et al, ), (10) Dongge (25°17′N, 108°05′E, Zhao et al, ), (11) Yongxing (31°35′N, 111°14′E, Chen et al, ), (12) Qixing (25°59′N,107°16′E, Zhang et al, ), and (13) Mawmluh (25°15′44″N, 91°52′54″E, Berkelhammer et al, ) caves. These records were chosen for their high‐resolution data, well‐constrained chronologies, and sufficient coverage of the weak ASM events.…”

“…Although these climate oscillations are not comparable to HSs in the last glacial period regarding the amplitude, duration, and remote effect, it has been suggested that AMOC variability could be involved in some cases (Bond et al, ; Ellison et al, ). The Bond events in Asian speleothem δ 18 O records generally fall within a range of 0.8 to 1‰ (see supporting information), which is indicative of a noticeable ASM decline during these periods (Berkelhammer et al, ; Dykoski et al, ; Liu, Henderson, et al, ; Liu et al, , ; Sinha et al, ; Zhao et al, ; Zhang et al, ). These cave records were constrained by precisely dated or annually counted chronologies that were well reproduced at a centennial scale.…”
