通过对气候敏感的沙漠/黄土过渡带中湖沼沉积进行高分辨率的~(14)C年代学和气候代用指标的研究,揭示了东亚季风气候存在着干冷(11.2～10.6kaBP)、湿凉(10.6～10.2kaBP)和干冷(10.2～10.0kaBP)的颤动特征。沙漠/黄土过渡带地处欧洲下风区,通过西风带与极地北大西洋气候相联系。晚冰期上述地区大气和海面温度变化引起西伯利亚～蒙古高压强度的变化,进一步影响东西区域性海-陆气压梯度的增强与减弱。因此,这一时期东亚季风气候这种百年尺度的快速颤动可视为高纬极地大陆气团与太平洋暖湿气团相互作用的写照。
Through the study of high-resolution (14) C geochronology and climatic proxy indicators in the climate-sensitive desert / loess transitional zone, it is revealed that the East Asian monsoon climate is characterized by dry and cold (11.2-10.6kaBP), cool and humid ~ 10.2kaBP) and dry and cold (10.2 ~ 10.0kaBP). The desert / loess transition zone is located in the downwind region of Europe and is linked to the polar North Atlantic climate by the westerlies. Changes of atmospheric pressure and sea surface temperature in the above glaciers during the late glacial ice caused the changes in the high-pressure intensities in Siberia and Mongolia, which further affected the enhancement and weakening of the regional sea-land pressure gradient. Therefore, the rapid quivering of the East Asian monsoon climate at this century-long scale can be regarded as a reflection of the interaction between the continental air masses in the high latitudes and the warm and humid air masses in the Pacific Ocean.
