英文摘要: Using simulations performed by all available climate models participating in the latest Paleoclimate Modelling Intercomparison Project (PMIP) phase 3 (PMIP3), we revisited the climate over China and the East Asian monsoon during the last glacial maximum (LGM; 21,000 years ago). Similar to previous results obtained from the PMIP phases 1 and 2 (PMIP1/2) models, all nine models reproduced colder than the pre-industrial annual and seasonal temperatures over China during the LGM and underestimated the annual cooling as evidenced by proxy data. The LGM annual and seasonal precipitation and evaporation over China consistently decreased in the models, whereas the very small LGM change in net precipitation (precipitation minus evaporation) differed among models. The annual net precipitation change during the LGM was broadly consistent with reconstructed moisture conditions over most parts of China, especially over the western Tibetan Plateau where the PMIP1/2 models disagreed with the proxy data. Moreover, the LGM winter monsoon circulation weakened (strengthened) over the East Asian continent in four (one) of five models; the summer monsoon circulation generally weakened in two models, whereas it weakened north and strengthened south of about 30°N over East Asia in three models. The spatial patterns of the LGM change in East Asian winter and summer monsoons in the PMIP3 models differed somewhat from those in the PMIP1/2 simulations. © 2016 Elsevier B.V. Citation statistics:
