The Surface Water and Ocean Topography (SWOT) mission resolves these features through wide-swath interferometry, but internal tides often mask these observations.

Conflict of Interest The authors declare no conflicts of interest relevant to this study. Data Availability Statement The monthly Niño 3.4 and DMI data are obtained from https://psl.noaa.gov/data/timeseries/month. Xmitgcm (Abernathey et al., 2021) and xgcm (Abernathey et al., 2022) are used for post-processing of the model simulations and for computation of the internal tide energy budget, respectively. ORAS5 data are obtained from the Copernicus Marine Service: https://doi.org/10.48670/moi-00024.

1 Introduction Internal tides (ITs), or baroclinic tides, are internal gravity waves that oscillate at tidal frequencies. Tidal flow over topographic features such as seamounts, mid-ocean ridges, and continental slopes cause vertical motions along the interfaces of ocean layers with varying densities to generate ITs (Bell, 1975; Wunsch, 1975).
