Three tiers of experiments in the Global Monsoons Model Intercomparison Project (GMMIP), one of the endorsed model intercomparison projects of phase 6 of the Coupled Model Intercomparison Project (CMIP6), are implemented by the First Institute of Oceanography Earth System Model version 2 (FIO-ESM v2.0), following the GMMIP protocols. Evaluation of global mean surface air temperature from 1870 to 2014 and climatological precipitation (1979–2014) in tier-1 shows that the atmosphere model of FIO-ESM v2.0 can reproduce the basic observed atmospheric features. In tier-2, the internal variability is captured by the coupled model, with the SST restoring to the model climatology plus the observed anomalies in the tropical Pacific and North Atlantic. Simulation of the Northern Hemisphere summer monsoon circulation is significantly improved by the SST restoration in the North Atlantic. In tier-3, five orographic perturbation experiments are conducted covering the period 1979–2014 by modifying the surface elevation or vertical heating in the prescribed region. In particular, the strength of the South Asian summer monsoon is reduced by removing the topography or thermal forcing above 500 m over the Asian continent. Monthly and daily simulated outputs of FIO-ESM v2.0 are provided through the Earth System Grid Federation (ESGF) node to contribute to a better understanding of the global monsoon system.

CMIP6 全球季风模型比对项目实验的 FIO-ESM v2.0 输出

全球季风模式比对项目 (GMMIP) 的三层实验是耦合模式比对项目 (CMIP6) 第 6 阶段认可的模式比对项目之一,由第一海洋学地球系统模型第 2 版 (FIO) 实施-ESM v2.0),遵循 GMMIP 协议。对1870-2014年全球平均地表气温和一级气候降水(1979-2014)的评估表明,FIO-ESM v2.0的大气模型可以再现基本观测到的大气特征。在第 2 层,耦合模型捕获内部变率,SST 恢复到模型气候学加上热带太平洋和北大西洋观测到的异常。北大西洋海温恢复显着改善了对北半球夏季风环流的模拟。在第 3 层中,通过修改指定区域的地表高程或垂直加热,进行了涵盖 1979-2014 年期间的五次地形扰动实验。特别是,通过去除亚洲大陆 500 m 以上的地形或热强迫,南亚夏季风的强度减弱。FIO-ESM v2.0 的月度和日模拟输出通过地球系统网格联盟 (ESGF) 节点提供,有助于更好地了解全球季风系统。通过修改指定区域的地表高程或垂直加热,在 1979-2014 年期间进行了五次地形扰动实验。特别是,通过去除亚洲大陆 500 m 以上的地形或热强迫,南亚夏季风的强度减弱。FIO-ESM v2.0 的月度和日模拟输出通过地球系统网格联盟 (ESGF) 节点提供,有助于更好地了解全球季风系统。通过修改指定区域的地表高程或垂直加热,在 1979-2014 年期间进行了五次地形扰动实验。特别是,通过去除亚洲大陆 500 m 以上的地形或热强迫,南亚夏季风的强度减弱。FIO-ESM v2.0 的月度和日模拟输出通过地球系统网格联盟 (ESGF) 节点提供,有助于更好地了解全球季风系统。
