中文摘要：

在这研究，作者在古气候建模 Intercomparison 工程(PMIP ) multimodels 模仿并且为冰川的海洋表面(MARGO ) 工程的重建由 Multiproxy 途径重建了的上次冰川的最大值(LGM ) 海表面温度(SST ) 调查了变化，集中于模型数据比较。结果证明 PMIP 模型生产了更大的海洋比 MARGO 在北方太平洋和热带海洋冷却，特别地在西北的太平洋，在 modeldata 失配更大的地方。所有模型没能在北方大西洋捕获异常东方西方 SST 坡度。另外，在模型之中的大差异在中间纬度的海洋被观察，特别地与在 PMIP 的第二个阶段的模型一起。尽管这些模型与 MARGO 显示出更好的同意，在 PMIP 的第三个阶段的最近的模型没在模仿 LGM 海洋表面条件显示出实质的进步。也就是说，在当模特儿的社区的改进仍然被需要在 LGM 期间为气候的更好的理解描述 SST。

英文摘要：

In this study,the authors investigated changes in Last Glacial Maximum （LGM） sea surface temperature （SST） simulated by the Paleoclimate Modelling Intercomparison Project （PMIP） multimodels and reconstructed by the Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface （MARGO） project,focusing on model-data comparison.The results showed that the PMIP models produced greater ocean cooling in the North Pacific and Tropical Ocean than the MARGO,particularly in the northwestem Pacific,where the modeldata mismatch was larger.All the models failed to capture the anomalous east-west SST gradient in the North Atlantic.In addition,large discrepancies among the models were observed in the mid-latitude ocean,particularly with models in the second phase of the PMIP.Although these models showed better agreement with the MARGO,the latest models in the third phase of the PMIP did not show substantial progresses in simulating LGM ocean surface conditions.That is,improvements in the modeling community are still needed to describe SST for a better understanding of climate during the LGM.
