Collaborative Research: Representing internal-wave driven mixing in global ocean models

这个气候过程小组的目标是制定和测试参数化的内波混合在海洋内部的最先进的耦合气候模式。内波混合被认为是控制海洋总体温盐结构的主要机制，可能对气候变异产生重大影响。该项目有望减少与气候模型无法明确解决的最小尺度物理过程相关的气候预测的不确定性。该项目将涉及海洋混合的三个方面：内波生成地点的近场混合、波场中传输的内波能破裂引起的混合以及远离源的内波能破裂引起的远场混合。参数化将基于波动物理学、辐射平衡理论和过程模型结果的数据关系。除了基于合理的理论思想外，参数化还将基于来自不断增长的微观结构观测数据集的观测结果。

The goal of this Climate Process Team is to formulate and test parameterizations for internal wave mixing in the ocean interior for inclusion in state of the art coupled climate models. Mixing by internal waves is thought to be a primary mechanism governing the overall thermohaline structure of the oceans, and may have significant implications for climate variability. The project promises to reduce the uncertainty in climate prediction associated with the smallest scale physical processes that cannot be explicitly solved by climate models. The project will address three aspects of ocean mixing: near field mixing at internal wave generation sites, mixing due to breakdown of internal wave energy transported in the wave field, and far field mixing due to breakdown of internal wave energy away from sources. Parameterizations will be based on data-based relations for wave physics, radiation balance theory, and results from process models. In addition to be being based on sound theoretical ideas, the parameterizations will also be based on observational results from the growing data set of microstructure observations.
