Climatic changes on millennial time scales--Evidence from a high-resolution loess record

摘要: Studies on a high resolution loess section in Huining County reveal that the behavior of climate shows instability during last glaciation. Results reflect Loess Plateau oscillates millennial time scales glacial period. These can be teleconnected with records Dansgaard-Oeschger cycles and Heinrich events latitudes. also demonstrate variations intensity wind regime have close correlation changes global ice sheets volume. All these suggest two-level fordngs may drive central Asia. The first level is volume second short superimposed upon nearly scale.
