Using the simulations performed by 15 climate models under the latest protocol of the Paleoclimate Modeling Intercomparison Project (PMIP) Phase 3 (PMIP3), the authors revisited the annual and seasonal temperature changes over China during the mid-Holocene. Similar to the previous results produced by PMIP Phase 1 (PMIP1) and 2 (PMIP2) models, 14 (15) of the 15 PMIP3 models reproduced colder annual (boreal winter and spring) temperature in response to mid-Holocene insolation changes, with an average cooling of 0.33 K (1.31 K and 1.58 K) over China. The mid-Holocene boreal summer (autumn) temperature increased in all (13) of the 15 PMIP3 models, with an average warming of 1.02 K (0.61 K) at the national scale. Those changes simulated by the PMIP3 models were similar to those from the PMIP2 simulations but generally weaker than those from the PMIP1 models. A considerable mismatch still existed between the simulated cooling by the PMIP3 models and the reconstructed warming for annual and winter temperatures over China during the mid-Holocene, as was also the case between the previous PMIP1/2 simulations and proxy data.
过去利用36个PMIP1/2模式试验数据研究发现，35个模式模拟全新世中期中国年和冬季偏冷，与多源地质记录显示的偏暖相反。为探究模式与记录不一致的原因，我们利用PMIP3试验中15个模式结果再次检查了全新世中期中国温度变化。结果表明：14（15）个模式模拟我国年平均（冬季）偏冷，这与PMIP1/2试验结果类似，PMIP3模式结果与地质记录仍然不一致，重建和模拟工作有待进一步开展。
