IAPSO/SCOR Conference on Ocean Mixing

知识价值：了解海洋混合过程对大规模海洋环流很重要。在一系列过程实验之后，对风和流、内波、海底地形和粗糙度、分层和混合之间相互作用的定量和定性理解正在迅速发展。在过去几年中，人们对潮汐与海底地形的相互作用及其对海洋混合的影响的兴趣日益浓厚。这种兴趣部分源于最近的分析和实地结果，这些结果表明，这些相互作用可以贡献很大一部分所需的能量，以迫使远离物理边界的海洋盆地进行混合。对这一机制的充分理解可能会增强我们对发生在空间尺度上的混合过程进行参数化的能力，这些混合过程比典型的涡旋解析海洋环流模式的网格尺度更小。这次国际会议由国际海洋物理科学协会（IAPSO）和海洋研究科学委员会（SCOR）的海洋混合问题工作组提议，将汇集海洋混合领域的主要科学家，作为IAPSO/SCOR工作组收集有关最近发现的信息的机制。更广泛的影响：改进的参数化方案可能会减少(1)模式正常运行所需的混合强度和(2)海洋中测量到的混合之间长期存在的数量级差异。模式参数化方面的这种改进应使建模者能够编制出其结果与观测结果更吻合的模式，并对海洋对全球变化的影响作出更准确和精确的预测。因此，拟议的活动可能会产生重要的社会影响。会议的结果将在《深海研究II》的特刊中进行总结，该特刊将记录该领域的状况，并将会议的信息更广泛地提供给无法参加会议的物理海洋学家和其他海洋科学家

Intellectual Merit: Understanding of ocean mixing processes is important for large-scale ocean circulation. A quantitative as well as a qualitative understanding of the interactions among winds and currents, internal waves, seafloor topography and roughness, stratification, and mixing is developing rapidly following a number of process experiments. Interest has heightened over the past few years in tidal interactions with seafloor topography and the ensuing impacts on ocean mixing. This interest stems in part from recent analytical and field results indicating that these interactions can contribute a significant portion of the energy needed to force mixing in ocean basins remote from physical boundaries. A full understanding of this mechanism may enhance our ability to parameterize mixing processes that occur at spatial scales smaller than the grid scales typifying even eddy-resolving ocean general circulation models. This international conference, proposed by a Working Group on Ocean Mixing of the International Association for the Physical Sciences of the Oceans (IAPSO) and the Scientific Committee on Oceanic Research (SCOR) will bring together the leading scientists in the field of ocean mixing to serve as a mechanism for the IAPSO/SCOR working group to gather information on recent findings, difficulties involved with parameterization of mixing in numerical ocean models and future directions and opportunities..Broader Impacts: Improved parameterization schemes may decrease the long-standing, order-of-magnitude disagreement between (1) mixing intensity needed in order for models to behave properly and (2) mixing measured in the ocean. Such improvements in model parameterizations should allow modelers to produce models whose results agree better with observations and result in more accurate and precise predictions of the effects of the ocean on global change. Thus, the proposed activity could have important societal impacts. The findings of the confer3ence will be summarized in a special issue of Deep-Sea Research II that will document the state of the field and make information from the conference available more broadly to physical oceanographers and other ocean scientists who are unable to attend the conference
