Eddy Transport in the Ocean: Analysis and Parameterization

本项目旨在发展一种封闭的理论形式，用于分析和模拟涡旋存在下的时间平均流动。在平衡流动的假设下，重点研究了位涡和示踪剂的涡旋输送。平衡假设将允许在散度（或动量）预算中进行必要的近似，以便围绕势涡和示踪剂输运的单个参数化关闭整个方程组。这项工作不仅将为全球海洋模式中涡动输送的参数化提供一个方案，而且还将为海洋环流分析提供一套概念工具。涡流解析模型将用于指导理论发展，并提供测试平台，以比较低分辨率模型与参数化涡流的结果。

Plumb 0095595This project is aimed at the development of a closed theoretical formalism for the analysis and modeling of time-mean flows in the presence of eddies. On the assumption of balanced flow, the approach is focused on eddy transport of potential vorticity and of tracers. Balance assumptions will allow necessary approximations to be made in the divergence (or momentum) budgets in order to close the entire system of equations around a single parameterization for the transport of potential vorticity and of tracers. It is intended that this work will produce not only a scheme for the parameterization of eddy transports in global ocean models, but also a set of conceptual tools for the analysis of the ocean circulation. Eddy resolving models will be used to guide the theoretical development, and to provide testbeds against which to compare results from lower resolution models with parameterized eddies.
