This project is a collaborative effort to use recent mathematical developments to improve numerical modeling of the World Ocean by considering how to parameterize how ocean currents interact with topography. Theories based on statistical mechanics calculations predict the flows that occur as the system evolves towards a state of maximum entropy. These flows will be used to develop parameterizations of how the flows interact with topography in coarsely resolved models and these models will then be compared to highly resolved models. The results will be used to develop parameterizations for the widely used POP and MOM models of ocean circulation which are widely used in climate prediction studies.

该项目是一项合作项目，旨在通过考虑如何参数化洋流与地形的相互作用，利用最新的数学发展来改进世界海洋的数值模拟。基于统计力学计算的理论预测了系统向最大熵状态演化时发生的流动。这些流将用于开发流如何与粗解析模型中的地形相互作用的参数化，然后将这些模型与高分辨率模型进行比较。研究结果将用于为气候预测研究中广泛使用的海洋环流 POP 和 MOM 模型开发参数化。
