Abstract: | The geographic extent of the climate oscillations during the last deglaciation is an open question in the world. Here a high
resolution climate record from a 16 000 C-14 a loess sequence in the northwestern margin of the Chinese Loess Plateau is reported.
Comparison with GISP2 record shows that all major climate oscillation (e. g. Oldest Dryas/ Boiling/ Older Dryas/ Allerod/
Younger Dryas) in the North Atlantic region also registered in the record. In addition, the sequence also contains some other
distinctive strengthened winter monsoon periods. It is suggested that a coupling mechanism operate between the two areas,
and climate oscillations in the North Atlantic region may not be a local phenomenon. |
