黄土高原粉尘物质的搬运、沉积过程与来自中高纬度地区的季风密切相关.在第四纪时期,由于高纬度地区的冰期条件变化(如大陆冰盖的厚度与范围等)可对西伯利亚-蒙古高压的强度和位置起很大程度的控制作用,从而导致冬季风的风力和风向作相应的改变.重建冬季风的演化历史将有助于我们深入理解在全球变化的背景下,东亚地区气候变化的动力机制.
The handling and deposition of dusty matter in the Loess Plateau are closely related to the monsoons coming from middle and high latitudes.In the Quaternary period, due to the changes of glacial conditions in high latitudes (such as the thickness and range of the continental ice sheet), the Siberian-Mongolian The intensity and location of high pressure play a significant role in controlling the wind and wind direction of the winter monsoon, and the evolution of the winter monsoon will help us to understand the climate change in East Asia in the context of global change The power mechanism.
