A computational database will be investigated for cyber-enabled discovery of spatio-temporal transport and mixing dynamics in geophysical turbulent flows modeled through simulation. It will be possible to identify vortical flow structures and follow them in time to compute conditional flow quantities, thereby, quantifying the dynamical role of these structures. The database provides an efficient extensible framework for formulating and validating hypotheses. It combines the machinery of an imperative model of spatial data retrieval with powerful computational facilities tailored to dynamic representations of irregular time-dependent structures, overcoming limitations of relational databases in handling such data. Broader impacts of this research are in its contributions to the national infrastructure for research and education in Computer Science, Geosciences and Mechanical and Aerospace Engineering; it will lead to a computational methodology applicable to any field that involves time-dependent, multi-scale physical phenomena and admits mathematical rules to characterize features that are posited to be dynamically important.Two Ph.D. students will be trained and will work together with collaborators outside their own fields, enabling cross-disciplinary teaching and training. Research results will be integrated into high-performance computing courses and the database will be used as a tool in graduate courses in turbulence and computational fluid dynamics. The software produced by the investigation will be disseminated publicly. The investigators will actively recruit from under-represented groups.

将研究一个计算数据库，以通过模拟模拟地球物理湍流中的时空传输和混合动力学。这将是可能的，以确定涡流结构，并按照他们的时间来计算条件流量，从而量化这些结构的动态作用。该数据库为制定和验证假设提供了一个有效的可扩展框架。它结合了一个强制性的空间数据检索模型的机械与强大的计算设施量身定制的动态表示不规则的时间相关的结构，克服了关系数据库在处理这些数据的局限性。这项研究的更广泛的影响是在其贡献的国家基础设施的研究和教育在计算机科学，地球科学和机械和航空航天工程;它将导致适用于任何领域的计算方法，涉及时间依赖性，多尺度的物理现象，并承认数学规则来表征被假定为动态重要的功能。学生将接受培训，并将与自己领域以外的合作者一起工作，从而实现跨学科的教学和培训。研究成果将被纳入高性能计算课程，数据库将被用作湍流和计算流体动力学研究生课程的工具。调查所产生的软件将公开分发。调查人员将积极从代表性不足的群体中招募人员。
