Abstract
As a member of the Chinese modeling groups, the coupled ocean-ice component of the Chinese Academy of Sciences’ Earth System Model, version 2.0 (CAS-ESM2.0), is taking part in the Ocean Model Intercomparison Project Phase 1 (OMIP1) experiment of phase 6 of the Coupled Model Intercomparison Project (CMIP6). The simulation was conducted, and monthly outputs have been published on the ESGF (Earth System Grid Federation) data server. In this paper, the experimental dataset is introduced, and the preliminary performances of the ocean model in simulating the global ocean temperature, salinity, sea surface temperature, sea surface salinity, sea surface height, sea ice, and Atlantic Meridional Overturning Circulation (AMOC) are evaluated. The results show that the model is at quasi-equilibrium during the integration of 372 years, and performances of the model are reasonable compared with observations. This dataset is ready to be downloaded and used by the community in related research, e.g., multi-ocean-sea-ice model performance evaluation and interannual variation in oceans driven by prescribed atmospheric forcing.
摘要
中国科学院地球系统模式2.0版CAS-ESM2.0参与了第六次国际耦合模式比较计划CMIP6并参加了海洋模式比较计划OMIP1。在该试验中,采用CAS-ESM2.0中的海洋海冰分系统耦合模式在给定1948−2009年core2的强迫下积分6个循环(共372年),模拟的月平均结果已发布在CMIP6的ESG数据服务器上。本文对该数据集进行了初步评估,包括全球海温、海表温度、海表盐度、海表高度、南北极海冰密集度、大西洋经圈翻转环流等。通过与观测对比表明,模式模拟的海洋基本变量较为合理。该数据集可供从事海洋多模式模拟比较、海洋的年际变化等相关研究的科学家下载使用。
