Abstract
The Tibetan Plateau, which is climatically dominated by the westerlies and the Asian monsoon, has a major influence on the atmospheric circulation and water resources of Asia. However, it remains unclear of the long‐term (e.g., millennial‐ and orbital‐scale) status and origin of the water resources in the plateau. In this study, we used the presence of a long‐distance pollen component (e.g., Tsuga) in a sedimentary section from eastern Pamir as a tracer to characterize the air movements in the western Tibetan Plateau during the late Holocene. Based on modern backward trajectory analysis, we suggest that the pollen of Tsuga was transported by the paleo‐monsoon from the southeastern Tibetan Plateau to eastern Pamir during the late Holocene (e.g., 3,200–1,750 cal years B.P.). Our findings provide evidence of paleo‐monsoon movement and potential moisture transport paths from the southeastern Tibetan Plateau to eastern Pamir during the late Holocene.
