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.

根据这项SGER赠款，PI将在社区气候系统模型（CCSM）的海洋部分实施基于物理的空间变化垂直扩散率参数化。最近的观测研究表明，在粗糙的海底地形上，海洋中的垂直混合会大大增强。PI将评估对海洋环流的影响，其热传输及其在气候中的作用。这项工作是重要的，因为它将提供强有力的诊断支持的模拟气候变率的CCSM使用一个新的物理为基础的计划，在海洋模型中的扩散。
