Abstract
The Flux-Anomaly-Forced Model Intercomparison Project (FAFMIP) is an endorsed Model Intercomparison Project in phase 6 of the Coupled Model Intercomparison Project (CMIP6). The goal of FAFMIP is to investigate the spread in the atmosphere-ocean general circulation model projections of ocean climate change forced by increased CO2, including the uncertainties in the simulations of ocean heat uptake, global mean sea level rise due to ocean thermal expansion and dynamic sea level change due to ocean circulation and density changes. The FAFMIP experiments have already been conducted with the Flexible Global Ocean-Atmosphere-Land System Model, gridpoint version 3.0 (FGOALS-g3). The model datasets have been submitted to the Earth System Grid Federation (ESGF) node. Here, the details of the experiments, the output variables and some baseline results are presented. Compared with the preliminary results of other models, the evolutions of global mean variables can be reproduced well by FGOALS-g3. The simulations of spatial patterns are also consistent with those of other models in most regions except the North Atlantic and the Southern Ocean, indicating large uncertainties in the regional sea level projections of these two regions.
摘要
通量距平强迫模式比较计划(FAFMIP)是第六次国际耦合模式比较计划(CMIP6)的比较计划之一。FAFMIP利用 CMIP6 中的大气-海洋耦合环流模式(AOGCM)对海表施加动量通量、热通量和淡水通量扰动,旨在研究在 CO2 强迫下模式模拟的海洋热吸收,由热膨胀引起的全球平均海平面上升,及由海洋密度和环流导致的动力海平面变化等方面的不确定性。本文简要介绍了中国科学院大气物理研究所开发的FGOALS-g3模式的FAFMIP模拟结果,该数据集已在地球系统网格联合会(ESGF)数据节点上发表共享。与参与FAMFIP的其他模式结果对比分析表明,FGOALS-g3可以基本再现变量的全球平均变化特征。除了北大西洋和南大洋以外,FGOALS-g3模拟的大部分区域的海平面空间分布特征与其他模式结果相一致,表明这两个区域的海平面变化模拟存在很大的不确定性。
