ABSTRACT In this paper, we investigate the vortex–wall interaction on the β-plane, using a submesoscale and internal waves resolving model in an idealised context. Our results bring new insights on the dynamics of oceanic mesoscale eddies as they drift toward a western boundary. We show that there exists a strong cyclone/anticyclone asymmetry in the interaction, contrary to what was suggested in previous studies: anticyclones cannot drift meridionally along the wall because of internal Kelvin Waves–current interactions. This interaction is shown to be an efficient mechanism to generate small coherent submesoscale cyclones, which can travel hundreds of kilometres into the interior of the ocean.

β 平面上的涡-壁相互作用和内部开尔文波-电流相互作用产生的深亚中尺度气旋

摘要在本文中，我们在理想化的环境中使用亚中尺度和内波解析模型来研究 β 平面上的涡-壁相互作用。我们的结果为海洋中尺度涡流向西部边界漂移的动力学带来了新的见解。我们表明相互作用中存在强烈的气旋/反气旋不对称性，这与先前研究中的建议相反：由于内部开尔文波 - 电流相互作用，反气旋不能沿壁沿经向漂移。这种相互作用被证明是产生小的连贯亚中尺度气旋的有效机制，它可以传播数百公里进入海洋内部。
