A high‐resolution monsoon record of millennial‐scale oscillations during Late MIS 3 from Wulu Cave, south‐west China
ABSTRACT A speleothem record from south‐western China characterizes in detail the millennial‐scale changes in Asian Monsoon (AM) intensity from 39.3 to 28.7 ka. The calcite δ 18 O profile, with an average resolution of ∼8 years, shows several strong monsoon events concurrent with Greenland Interstad...
