Breaking Internal Waves on Sloping Topography: Connecting Parcel Displacements to Overturn Size, Interior-Boundary Exchanges, and Mixing
Published in Journal of Phsyical Oceanography, 2025
Using LES, this work looks at the internal tide breaking process on sloping bottom topography, finding a strong dependence on the length scale we term the ‘effective wave height’ from the initial overtuns to the ejection of near-boundary fluid into the interior. There is also a discussion of the subsequent water-mass transformation and mixing in the BBL using both a volume budget and buoyancy fluxes.
