Turbulent mixing is a crucial driver of heat and nutrient and current distributions through the world oceans. Away from direct atmospheric surface forcing, most of the turbulent mixing in the ocean interior is driven by breaking internal gravity waves. Global levels and patterns of mixing are hence set by the detailed geography of internal wave generation, propagation and breaking. The NSF-funded Climate Process Team (CPT) on ocean mixing has been working for the past five years to develop, implement, test and refine new parameterizations of diapycnal (vertical) mixing for use in global ocean and coupled climate models. In particular, the CPT has concentrated on turbulent mixing due to breaking internal waves, including internal tides, wind-driven near-inertial internal waves, and more recently, internal lee waves. In all cases the diverse membership of the CPT, consisting of sea-going observationalists, theorists, those doing numerical process studies, and members of two national modeling centers, has allowed multi-faceted approaches to tackling these issues. Thirty to forty participants are expected for this workshop, including a few international scientists and a good number of early career scientists. This workshop will further our ability to understand and improve the veracity of the ocean component of climate models. Improved climate models will benefit many fields within oceanography, as well as the ability for society as a whole to anticipate and adapt to a changing climate as effectively as possible.The workshop has multiple goals. The first goal is to pull together the collective state of knowledge from both the members of the Climate Process Team on Ocean Mixing and invited participants on topics including the global geography of diapycnal mixing, associated global energy budgets, the net influence and model sensitivity to the different processes, and best practice tools and techniques that span multiple process experiments. Intensive working time will allow for active collaboration between participants working on similar problems. Finally, participants will reconvene to identify issues that need concentrated work, steps forward, and step back to consider the most interesting and important open questions for the field as a whole in the decade to come. Three clear outcomes are anticipated: a reenergized level of communication and understanding within the active turbulent mixing community; the dissemination of several products for broad community use, including the microstructure observations database, the CVMIX repository of code modules, and a best practices website of commonly used observational analysis techniques and a whitepaper summarizing our collective state of the field knowledge.

湍流混合是热量和营养物以及洋流在世界海洋中分布的一个关键驱动因素。 远离直接的大气表面强迫，海洋内部的大部分湍流混合是由破碎的内部重力波驱动的。 因此，全球的混合水平和模式是由内波产生、传播和破碎的详细地理情况决定的。在过去的五年里，NSF资助的海洋混合气候过程小组（CPT）一直致力于开发，实施，测试和完善用于全球海洋和耦合气候模型的纵贯（垂直）混合的新参数化。特别是，CPT集中在湍流混合由于打破内波，包括内潮汐，风驱动的近惯性内波，最近，内部背风波。在所有情况下，CPT的成员组成的不同，包括航海观测，理论家，那些做数值过程研究，和两个国家模拟中心的成员，允许多方面的方法来解决这些问题。预计将有30至40名与会者参加这次研讨会，其中包括一些国际科学家和许多早期职业科学家。这次研讨会将进一步提高我们理解和提高气候模型海洋部分准确性的能力。改进的气候模型将使海洋学的许多领域受益，并提高整个社会尽可能有效地预测和适应气候变化的能力。研讨会有多个目标。第一个目标是汇集海洋混合气候过程小组成员和受邀与会者的集体知识状态，主题包括全球地理的纵贯混合，相关的全球能源预算，不同过程的净影响和模型敏感性，以及跨越多个过程实验的最佳实践工具和技术。密集的工作时间将使从事类似问题工作的参与者能够积极合作。最后，与会者将再次召开会议，确定需要集中工作的问题，向前迈进，并后退一步，考虑未来十年整个领域最有趣和最重要的开放问题。三个明确的结果是预期的：活跃的湍流混合社区内的沟通和理解的重新激活的水平;传播的几个产品广泛的社区使用，包括微观结构观测数据库，代码模块的CVMIX存储库，和常用的观测分析技术的最佳实践网站和白皮书总结我们的集体状态的领域知识。
