Abstract |
|
内容記述 |
Near-inertial and double-inertial internal waves (NIWs and DIWs) are frequently observed in the frontal region of the Sea of Japan during typhoon events. However, the mechanisms behind their generation, propagation, and dissipation, particularly under the influence of mesoscale structure of the Tsushima Warm Current (TWC), remain unclear. This study employs a numerical model with wind forcing from Typhoon Tapah (September 2019) to investigate these wave behaviors. Two experiments, one with the TWC (WITH-TWC) and one without it (NO-TWC), reveal striking contrasts. The TWC generates mesoscale features with negative relative vorticity, which effectively trap NIWs and prevent their escape. DIWs, in contrast, grow rapidly, radiate poleward, and dissipate within a few days. Modal dispersion theory explains how NIWs remain confined to mesoscale features, while DIWs and higher-frequency waves escape due to their higher group velocities. The DIW wave energy concentrates predominantly in the lowest vertical modes (typically, 1st–3rd), enabling efficient long-distance energy transfer with minimal distortion. A statistical analysis further indicates that regions of negative vorticity coincide with enhanced wave kinetic energy, especially for NIWs, supporting the interpretation that anticyclonic eddies act as effective traps and amplifiers of wave energy. These findings underscore the critical role of mesoscale eddies in regulating energy pathways of typhoon-induced internal waves, advancing general understanding of ocean mixing and energy redistribution in the Asian marginal seas. |
