Modeled Physics for Ocean Climate Research

本研究通过数值模拟考察了海洋在气候变化中的作用。该方法有三个组成部分：1)利用现有的大尺度三维海洋模型探索其对亚网格尺度表示的敏感性；2)利用有限区域理想化过程模型对亚网格尺度表示进行细化；3)利用地球物理流体动力学的理论结果来组织调查。该项目将解决交叉密度混合，底部地形的影响，以及热量，动量，涡度和化学成分的横向通量。这些结果的应用将对气候影响研究和生物地球化学具有重要意义。

This study examines the role of oceans in climate change via numerical modeling. The approach has three components: 1) use existing large-scale 3-dimensional ocean models to explore their sensitivity to sub-grid scale representations, 2) use limited area idealized process models to refine the sub-grid scale representations, 3) use theoretical results from geophysical fluid dynamics to structure the investigation. The project will address the cross-density mixing, effects of bottom topography, and the lateral fluxes of heat, momentum, vorticity, and chemical constituents. Application of the results will be important for climate impact studies, and for biogeochemistry.
