中文摘要：中尺度涡垂向流速在海洋物质和能量输送、调节全球碳氧循环和理解涡旋动力学中扮演着重要角色,是近年来海洋学热点问题之一。本文从空间结构、时间演变和调控机制等不同角度,系统地归纳了海洋中尺度涡垂向流速的研究进展。基于数值模拟和动力诊断的结果显示,中尺度涡垂向流速在不同分辨率下有所不同。中尺度分辨率下,垂向流速的水平分布以偶极子或四极子结构为主,而亚中尺度下,则主要为正负交替的螺旋涡丝状结构且流速增强。与水平流速类似,中尺度涡垂向流速呈现涡心弱、边缘强的特征,常在次表层达到最大值。对于中尺度涡垂向流速的时间演变,数值模拟与实测诊断合成的结果存在明显差异,亟待更多研究。中尺度涡垂向流速受涡度的平流、涡旋的传播和变形、亚中尺度过程、涡-风相互作用、涡-涡相互作用和地形强迫等多种机制调控,其与调控机制的量化关系有待发展。此外,次表层涡旋的报道日渐增多,其垂向流速性质有待探究。

外文摘要：The vertical velocity within mesoscale eddies plays a crucial role in ocean energy and mass transport,carbon-oxygen cycle and eddy dynamics,and thus becomes a hot topic in the research of ocean mesoscale-submesoscale processes.This overview paper aims to review the recent progress in research in this field and systematically summarize the spatial structure,evolution pattern and regulating mechanism of eddy vertical velocities.Numerical modeling and dynamic diagnosis have revealed that the structure and intensity of eddy vertical velocities is highly resolution-dependent.At mesoscale,the vertical velocity within eddies mainly shows a horizontal dipole structure,while strong alternating positive and negative spiral filaments appear in the case of submesoscale resolution.The vertical velocities are generally weak at eddy center but strong at the edge.Vertically,maximum values are mostly found in the subsurface layer.For the temporal evolution of eddy vertical velocities,the results derived from numerical models differ from that derived from observation estimates.On the other hand,evolution of vertical velocities during the eddy lifecycle remains insufficiently characterized.Meanwhile,multiple mechanisms modulate the eddy vertical velocity,including the advection of vorticity,eddy propagation and deformation,submesoscale progresses,eddy-wind interaction,eddy-eddy interaction and topography forcing.Quantifying the relative contribution of these mechanisms to the vertical velocity remains a challenge.Furthermore,the vertical velocity within subsurface intensified anomaly eddies is also worth pursuing.
