Material transport in the ocean mixed layer (OML) is an important component of natural processes such as gas and nutrient exchanges. It is also important in the context of pollution (oil droplets, microplastics, etc.). Observational studies of small-scale three-dimensional turbulence in the OML are difficult, especially if one aims at a systematic coverage of relevant parameters and their effects, under controlled conditions. Numerical studies are also challenging due to the large-scale separation between the physical processes dominating transport in the horizontal and vertical directions. Despite this difficulty, the application of large eddy simulation (LES) to study OML turbulence and, more specifically, its effects on material transport has resulted in major advances in the field in recent years. In this paper we review the use of LES to study material transport within the OML and then summarize and synthesize the advances it has enabled in the past decade or so. In the first part we describe the LES technique and the most common approaches when applying it in OML material transport investigations. In the second part we review recent results on material transport obtained using LES and comment on implications.

海洋混合层中的物质传输:大涡模拟支持的最新发展

作者(S):Chamecki,M;楚,T; 杨,D;Meneveau, C | 摘要:©2019。美国地球物理联合会。版权所有。海洋混合层 (OML) 中的物质运输是天然气和营养交换等自然过程的重要组成部分。在污染(油滴、微塑料等)的情况下,这也很重要。OML 中小尺度三维湍流的观测研究是困难的,特别是如果一个目标是在受控条件下系统地覆盖相关参数及其影响。由于主导水平和垂直方向传输的物理过程之间的大规模分离,数值研究也具有挑战性。尽管存在这个困难,大涡模拟(LES)在研究 OML 湍流中的应用,更具体地说,近年来,它对材料运输的影响使该领域取得了重大进展。在本文中,我们回顾了使用 LES 来研究 OML 内的物质传输,然后总结和综合它在过去十年左右取得的进展。在第一部分中,我们描述了 LES 技术和在 OML 材料运输调查中应用它时最常用的方法。在第二部分中,我们回顾了使用 LES 获得的材料运输的最新结果并评论了影响。在第一部分中,我们描述了 LES 技术和在 OML 材料运输调查中应用它时最常用的方法。在第二部分中,我们回顾了使用 LES 获得的材料运输的最新结果并评论了影响。在第一部分中,我们描述了 LES 技术和在 OML 材料运输调查中应用它时最常用的方法。在第二部分中,我们回顾了使用 LES 获得的材料运输的最新结果并评论了影响。
