However, the evidence of past glaciations differs greatly between Western and Eastern Alps, while contrast between Southern and Northern Alps is not evident. The main purpose of this paper is to interpret variability of humidity during the last interglacial-glacial cycle in the Alpine region, based on results of various surveys performed in the Alpine region. Results show that distribution of moisture throughout the Alps was most even during the Late Würmian, while precipitation was mainly concentrated in the (North)Western Alps during the Early Würmian and in the (North)Western and along all the Southern Alps during the Middle Würmian. The Eastern Alps were rather dry during both episodes. Such moisture distribution can be explained by paths of prevailing winds. Moisture distribution is directly linked with atmospheric and oceanic circulation.展开更多
