英文摘要The 8.2 ka event has been extensively studied, whereas its structure is ambiguous in North China. Here we present a high-resolution (similar to 1 year) delta O-18 record from annual laminated speleothem from Beijing to characterize the detailed variability across this event in North China. Our record indicates a dry 8.2 ka event spanning 8.254-8.107 ka BP with a two-stage structure superimposed by three prominent high delta O-18 excursions. The identical structure of speleothem delta O-18 records between North and central China during the event suggests a common forcing/response in East China, whereas the progressively increased offset between their average values may reflect changes in moisture source or rainout effect. A close comparison with the Greenland ice core records suggests a strong linear response of the Asian summer monsoon to the North Atlantic climate changes across the early and middle stages of the event, but a different mechanism in the termination processes.
