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 ka B.P. to 29.2 ka B.P., 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 monsoon characteristics more closely resemble, but are anti-correlated 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.
