HIGH-RESOLUTION STALAGMITE δ¹⁸O RECORDS OF ASIAN MONSOON CHANGES IN SOUTHWEST GUIZHOU DURING THE LATE EPISODE OF MIS3: A TEST OF THE BI-POLAR SEE-SAW MODEL AT CENTENNIAL SCALE

A 10-year resolution oxygen isotope record from the Wulu Cave, based on 9 precise ²³⁰Th dates and 1 317 oxygen isotope measurements, provides a detailed history of the Asian Monsoon from 39.1 kaBP to 29.2 kaBP, spanning the marine isotope stage 3.The fairly good replication of δ¹⁸O signal between the Wulu Cave and the Hulu Cave during the same growth periods indicates that the δ¹⁸O signals well recorded climatic changes and the changes in the monsoon system were are similar over a large area of China. The comparison between the Wulu Cave and Greenland ice core record indicates that the frequency of centennial and millennial scale monsoon events match well with the temperature in North high latitude. Our monsoon characteristics more closely resemble, but are anticorrelated with the features in the Antarctic record, indicating some sort of link to the climate in the high southern latitudes. It means that the Asian monsoon intensity may be impacted by cross-equatorial flow driven by the low temperature of the southern ocean and the change in the vapor heat release. It is believed that the low-latitude monsoon and Antarctic temperature responded to each other in a "see-saw" mode on centennial-millennial scales.
