摘要
末次间冰期有着丰富的重建和模拟资料,为研究未来温暖气候提供了一个理想的参考.然而,关于末次间冰期的东亚气候,模拟与重建的结果间长期存在着不匹配的情况,模拟结果普遍较重建结果更为冷干。本研究利用挪威地球系统模式(NorESM1-F),探讨了在末次间冰期模拟试验中纳入全球平均海平面上升能否减少模式-数据的不匹配.该试验结果表明,海平面上升情况下东亚地区会产生一定的增温增湿效应,但不足以消除模式-数据不匹配.基于这些结果,作者探讨了其它可能造成不匹配的因素以供进一步研究.
The Last Interglacial(LIG),with its many reconstructions and simulations,provides an ideal analog for investigating the future warmer climate.However,there has been a persistent mismatch between simulated and reconstructed LIG climates in East Asia,with simulations generally indicating a colder and drier climate than reconstructions.In this study,utilizing the Norwegian Earth System Model(NorESM1-F),the authors investigated whether incorporating the global mean sea-level rise in LIG simulation experiments can reduce the model-data mismatch.The new experiments reveal a discernible,yet insufficient,warming and wetting effect in East Asia resulting from the sea-level rise.Therefore,the model-data mismatch remains unresolved.Based on these results,the authors explore alternative factors that may contribute to this mismatch,offering insights for future studies.
