SGER: Parameterizing Vertical Mixing in the Ocean Component of the Community Climate System Model (CCSM)

在SGER的资助下，PI将在社区气候系统模式（CCSM）的海洋分量中实现基于物理的空间变化垂直扩散的参数化。最近的观测研究表明，在崎岖的海底地形上，海洋中的垂直混合可以得到强烈加强。该项目将评估对海洋环流的影响、热输送及其在气候中的作用。这项工作是重要的，因为它将为CCSM模拟气候变率提供强有力的诊断基础，使用一种新的基于物理的海洋模式扩散方案。

Under this SGER grant, the PI will implement a physically-based parameterization of the spatially varying vertical diffusivity in the ocean component of the Community Climate System Model (CCSM). Recent observational studies show vertical mixing in the ocean can be strongly enhanced over rough bottom topography. The PI will evaluate the impact on the ocean's circulation, its heat transport and its role in climate. The work is important because it will provide strong diagnostics underpinning of simulated climate variability of the CCSM using a new physically-based scheme for diffusivity in the ocean model.
