了解大尺度大气系统的过去动态对我们了解欧洲的古气候条件至关重要。东南欧目前位于大西洋、地中海和大陆性气候带的交界处。过去相关大气系统相对影响的变化一定记录在该地区的古档案中。通过比较多瑙河下游盆地两个黄土-古土壤序列的高分辨率粒度、环境磁和地球化学数据与欧亚大陆其他古记录，我们重建了东南欧过去的气候模式以及欧洲主要大尺度环流模式的相关相互作用，特别是在海洋同位素阶段3晚期（40,000-27,000年前）。我们证明，在这段时间间隔内，西伯利亚高压的增强对欧洲气候产生了至关重要的影响，导致欧洲主要地区的大陆条件增加，西风带向南移动。这样的气候和环境变化，加上坎帕尼亚Ignimbrite/Y-5火山喷发，可能推动了解剖学上的现代人向中欧和西欧的扩散，指出了东欧平原上的一条走廊是他们扩散的重要途径。
Understanding the past dynamics of large-scale atmospheric systems is crucial for our knowledge of the palaeoclimate conditions in Europe. Southeastern Europe currently lies at the border between Atlantic, Mediterranean, and continental climate zones. Past changes in the relative influence of associated atmospheric systems must have been recorded in the region’s palaeoarchives. By comparing high-resolution grain-size, environmental magnetic and geochemical data from two loess-palaeosol sequences in the Lower Danube Basin with other Eurasian palaeorecords, we reconstructed past climatic patterns over Southeastern Europe and the related interaction of the prevailing large-scale circulation modes over Europe, especially during late Marine Isotope Stage 3 (40,000–27,000 years ago). We demonstrate that during this time interval, the intensification of the Siberian High had a crucial influence on European climate causing the more continental conditions over major parts of Europe, and a southwards shift of the Westerlies. Such a climatic and environmental change, combined with the Campanian Ignimbrite/Y-5 volcanic eruption, may have driven the Anatomically Modern Human dispersal towards Central and Western Europe, pointing to a corridor over the Eastern European Plain as an important pathway in their dispersal.
