英文摘要 | The mid-Pleistocene transition (MPT) of the global climate system, marked by a shift of previously dominant 41-ka cycles to lately dominant 100-ka cycles roughly in the mid-Pleistocene, is one of the fundamental enigma in the Quaternary climate evolution. The process and origin of the MPT remain of persistent interest and conjecture. Here we present high-resolution astronomically tuned magnetic susceptibility (MS) and grain-size records from a complete loess-paleosol sequence at Chaona on the central Chinese Loess Plateau. These two proxies are well-known sensitive indicators to the East Asian summer and winter monsoons, respectively. The records reveal a remarkable two-step simultaneous enhancement of the East Asian summer and winter monsoons at 0.9 Ma and 0.64 Ma, respectively, accompanied with an onset of a clear 100-ka cycle at 0.9 Ma and of a final, predominant 100-ka cycle starting at 0.64 Ma. The mid-Pleistocene stepwise rapid uplift of the Tibetan Plateau could be the mechanism driving the simultaneous enhancement of East Asian summer and winter monsoons and the shift of the periodicities during the kin by complex positive feedbacks.
