耦合模式比较计划（CMIP）是气候模拟研究领域的重要国际合作平台，服务于气候模式比较、气候变率、气候预测和气候预估。改善气候模式在东亚和西北太平洋地区的模拟性能，一直是气候模式领域面临的一项挑战。针对第五次耦合模式比较计划（CMIP5）中的气候模式，本文提供了综合鲁棒性分析。本文从气候平均态、年际变率、中上新世（MP）和过去千年的历史气候变化、气候预估的角度，对CMIP5 模式的优缺点进行了评估。另外，还评估了区域气候模式相对于驱动其运行的全球气候模式带来的模拟增值。从CMIP3 到CMIP5，模式的可信度明显提高，气候平均态、年际变率和过去气候变化的模拟情况有所改善，但在CMIP5 模式中，一些之前已知的偏差，如西北太平洋副热带高压脊线的位置和与之相关的降水偏差等，仍然很明显。对于年际振幅的模拟也存在明显的缺陷，如厄尔尼诺- 南方涛动（ENSO）与季风的关系。在模拟平均气候态和年际变率时，耦合模式的表现通常优于单独大气模式。多模式比较的结果表明，尽管在克劳修斯- 克拉珀龙方程约束下模式预估的降水一致增加，但未来气候预估仍存在明显的不确定性。对东亚- 西北太平洋地区的动力降尺度预估而言，区域海洋- 大气耦合模式是一个较好的选择。

The Coupled Model Intercomparison Project (CMIP) is an international community-based infrastructure that supports climate model intercomparison, climate variability, climate prediction, and climate projection. Improving the performance of climate models over East Asia and the western North Pacific has been a challenge for the climate-modeling community. In this paper, we provide a synthesis robustness analysis of the climate models participating in CMIP-Phase 5 (CMIP5). The strengths and weaknesses of the CMIP5 models are assessed from the perspective of climate mean state, interannual variability, past climate change during the mid-Pliocene (MP) and the last millennium, and climate projection. The added values of regional climate models relative to the driving global climate models are also assessed. Although an encouraging increase in credibility and an improvement in the simulation of mean states, interannual variability, and past climate changes are visible in the progression from CMIP3 to CMIP5, some previously noticed biases such as the ridge position of the western North Pacific subtropical high and the associated rainfall bias are still evident in CMIP5 models. Weaknesses are also evident in simulations of the interannual amplitude, such as El Niño-Southern Oscillation (ENSO)-monsoon relationships. Coupled models generally show better results than standalone atmospheric models in simulating both mean states and interannual variability. Multi-model intercomparison indicates significant uncertainties in the future projection of climate change, although precipitation increases consistently across models constrained by the Clausius-Clapeyron relation. Regional ocean-atmosphere coupled models are recommended for the dynamical downscaling of climate change projections over the East Asia-western North Pacific domain.
