SGER: Causes and Consequences of Errors in the Simulation of the North Atlantic Current in Community Climate System Model (CCSM)

这项工作的科学重点是了解在共同体气候系统模式(CCSM)中模拟北大西洋洋流路径的系统误差的动力学原因，并诊断在更广泛的气候系统中海洋表面温度、表面通量和海洋输送所产生的误差的后果。科学方法将是在标准分辨率CCSM海洋模拟和耦合模拟以及过去几年进行的大量高分辨率并行海洋模式海洋模拟中分析这一洋流系统的动力和热力学平衡。这项研究的结果将用于指导未来版本的CCSM在非涡旋分辨和涡旋分辨分辨率下的海洋组件模式配置决策。更广泛的影响：CCSM在世界各地被数百名科学家和学生使用。因此，CCSM性能的提高使大量气候科学家受益。

The scientific focus of this effort is to understand the dynamical causes of systematic errors in the simulation of the path of the North Atlantic Current in the Community Climate System Model (CCSM), and to diagnose the consequences of the resulting errors in sea surface temperature, surface fluxes, and ocean transports on the broader scale climate system. The scientific approach will be to analyze the dynamical and thermodynamic balances of this current system in both standard resolution CCSM ocean only and coupled simulations, as well as a plethora of high-resolution Parallel Ocean Model (POP) ocean-only simulations that have been conducted in the last several years. The outcome of this study will be used to guide ocean component model configuration decisions in future versions of CCSM at both non-eddy-resolving and eddy-resolving resolutions. Broader impacts: The CCSM is used by a couple of hundred scientists and students, worldwide. Improved performance of the CCSM, therefore, benefits a large number of climate scientists.
