近日，我室延伸团队成员张永垂副教授关于次中尺度涡旋现象的研究成果被SCI期刊Ocean Dynamics接受并发表。该文章由国防科技大学张永垂为第一作者，国防科技大学陈希教授为通讯作者，实验室主任董昌明教授和西北工业大学工程师汪洋为合作作者共同发表。
Recently, OMOL’s extended team member, associate professor Yongchui Zhang’s research on submesoscale eddy phenomena was accepted and published by the SCI journal Ocean Dynamics. This joint publication featured the National University of Defense Technology (NUDT)-affiliated Yongchui Zhang as the first author, NUDT-affiliated Xi Chen as the corresponding author, in junction with OMOL’s director, Professor Changming Dong and Northwestern Polytechnic University’s Yang Wang.
论文题目为“Observation of submesoscale turbulence in a cyclonic eddy”。次中尺度，作为海洋中尺度动能耗散的通道，其尺度在一阶斜压Rossby波变形半径和湍流边界层厚度尺度之间，在海洋能量平衡中发挥重要作用。在本次工作中，根据黑潮延伸体海洋中尺度涡旋网格化观测数据，采用Helmholtz和波涡分解方法将涡旋分为中尺度涡（地转涡旋）和次中尺度（惯性-重力波）两部分，定量确定了从中尺度到亚中尺度的过渡长度尺度以及次中尺度和深度的关系。该文章条理清晰，视角独特，为涡旋现象的研究和应用提供了新的思路和方法。
Entitled “Observation of submesoscale turbulence in a cyclonic eddy”, the article explores the submesoscale, lying between the first Rossby baroclinic radius of deformation and the thickness of the turbulent boundary layer, forms a pathway for ocean mesoscale kinetic energy dissipation and plays a crucial role in oceanic energy balance. In that paper, based on gridded observational data of a mesoscale eddy in the Kuroshio Extension region, Helmholtz and wave-vortex decomposition was employed to decompose the eddy into mesoscale (geostrophic) and submesoscale (inertia-gravity waves) components which allowed for the quantitative determination of the length-scale of transition from mesoscale and submesoscale, and relationship between the submesoscale and depth. The article is well-constructed, possesses a unique perspective and provides new insight and methodologies in both the theoretical research and practical applications of eddies.
