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.

这个气候过程团队的目标是制定和测试海洋内部内部波混合的参数化，以纳入最新的气候模型。内部波被认为是管理海洋整体嗜热结构的主要机制，并且可能对气候变异性具有重要意义。该项目有望减少与最小规模的物理过程相关的气候预测的不确定性，而气候模型无法明确解决。该项目将解决海洋混合的三个方面：内部波生成位点的近场混合，由于波场中的内波能分解而导致的混合，以及由于内部波能量远离源的破坏而导致的远场混合。参数化将基于波浪物理，辐射平衡理论的基于数据的关系以及过程模型的结果。除了基于合理的理论思想之外，参数化还将基于根据微观结构观察的增长数据集的观察结果。
