Workshop On Ocean Mixing: Recent results and future prospects from combining process studies, theory and numerical modeling approaches; Scripps Inst.; Oct.27-29, 2015

湍流混合是全球海洋中热量、营养物质和洋流分布的关键驱动力。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内部重力波的破碎驱动的。因此，混合的全球水平和模式是由内波产生、传播和破裂的详细地理情况决定的。由美国国家科学基金会资助的海洋混合气候过程小组（CPT）在过去五年中一直致力于开发、实施、测试和完善用于全球海洋和耦合气候模型的垂直混合的新参数化。CPT特别关注由破碎内波引起的湍流混合，包括内潮、风驱动的近惯性内波，以及最近的内背风波。在所有情况下，CPT的不同成员，包括海上观测者、理论家、从事数值过程研究的人员，以及两个国家模拟中心的成员，允许采用多方面的方法来解决这些问题。预计将有30至40名与会者参加本次研讨会，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式中海洋成分准确性的能力。改进的气候模式将使海洋学的许多领域受益，也将使整个社会尽可能有效地预测和适应气候变化的能力受益。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参与者的集体知识，涉及的主题包括：海底混合的全球地理、相关的全球能源预算、不同过程的净影响和模式敏感性，以及跨越多个过程实验的最佳实践工具和技术。密集的工作时间将允许从事类似问题的参与者之间进行积极的协作。最后，与会者将再次聚集在一起，确定需要集中精力工作的问题，向前迈进，并退后一步，考虑未来十年整个领域最有趣和最重要的开放性问题。预计会有三个明确的结果：在活跃动荡的混合社区中，沟通和理解的水平将重新焕发活力；为社区广泛使用的几个产品的传播，包括微观结构观测数据库，代码模块的CVMIX存储库，以及常用观测分析技术的最佳实践网站和总结我们的领域知识集体状态的白皮书。

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.
