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.

Plumb 0095595该项目旨在开发一种封闭的理论形式主义，用于分析和模拟存在涡流的时间平均流。在平衡流的假设下，该方法着重于位涡和示踪剂的涡动输运。平衡假设将允许在散度（或动量）收支中进行必要的近似，以便围绕位涡和示踪物输运的单个参数化来封闭整个方程系统。这项工作的目的不仅是为全球海洋模式中的涡旋输送参数化制定一个方案，而且还为分析海洋环流提供一套概念工具。涡分辨模型将用于指导理论的发展，并提供测试平台，以比较低分辨率模型与参数化涡的结果。
