Shift of large-scale atmospheric systems over Europe during late MIS 3 and implications for Modern Human dispersal
Abstract 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...
