Ocean mixing is relevant for climate because it drives vertical transport of water, heat, carbon and other tracers. Understanding the life cycle of internal waves, from generation to dissipation, is therefore important for improving the representation of ocean mixing in climate models. Here, we provide evidence from a regional realistic numerical simulation in the northeastern Pacific that the wind can play an important role in damping internal waves through current feedback. This results in a reduction of 67% of wind power input at near-inertial frequencies in the region of study. Wind-current feedback also provides a net energy sink for internal tides, removing energy at a rate of 0.2 mW/m 2 on average, corresponding to 8% of the local internal tide generation at the Mendocino ridge. The temporal variability and modal distribution of this energy sink are also investigated. specialized PACIFIQUE ETATS UNIS 032 13 1 5915 [11 p.] 2023 2045-2322 https://www.documentation.ird.fr/hor/fdi:010088110 10.1038/s41598-023-32909-6 2045-2322 [F B010088110] https://www.documentation.ird.fr/hor/fdi:010088110 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2023-07/010088110.pdf IRD - Base Horizon / Pleins textes 2023-07-06 2025-02-24 fdi:010088110 fre
