Semidiurnal internal tide incoherence in the equatorial Pacific [PDF]

Journal of Geophysical Research: Oceans, 2017
AbstractThe jets in the equatorial Pacific Ocean of a realistically forced global circulation model with a horizontal resolution of cause a strong loss of phase coherence in semidiurnal internal tides that propagate equatorward from the French Polynesian Islands and Hawaii.

Disentangling Internal Tides From Balanced Motions With Deep Learning and Surface Field Synergy

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract A fundamental challenge in ocean dynamics is disentangling balanced motions and internal waves. Extracting internal tidal (IT) imprints from surface data is a central part of this challenge. Traditional harmonic analysis fails under strong incoherence and poor temporal sampling, as in global satellite observations.

Surface Thermal Tides and Radiative Adjustment in Venus's Deep Atmosphere

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Thermal tides on Venus have been extensively studied near the cloud tops, where their three‐dimensional structure and contribution to the atmospheric momentum budget have been characterized from temperature and wind fields. However, their downward propagation and influence within the deep atmosphere remain uncertain, and their behavior in the ...

Process-based modelling of nonharmonic internal tides using adjoint, statistical, and stochastic approaches – Part 1: Statistical model and analysis of observational data [PDF]

Ocean Science
A substantial fraction of internal tides cannot be explained by (deterministic) harmonic analysis. The remaining nonharmonic part is considered to be caused by random oceanic variability, which modulates wave amplitudes and phases.

Modeling Semidiurnal Internal Tide Variability in the Southern California Bight

Journal of Physical Oceanography, 2012
Abstract The Regional Oceanic Modeling System (ROMS) is applied in a nested configuration with realistic forcing to the Southern California Bight (SCB) to analyze the variability in semidiurnal internal wave generation and propagation. The SCB has a complex topography with supercritical slopes that generate linear internal waves at the ...

Assessing Dynamical Contributions to SWOT Sea Surface Height in an Internal Tide Hotspot

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission has revealed high‐frequency sea surface height anomaly (SSHA) variability associated with internal gravity waves, yet comparison with in situ observations remains limited. Here, we analyze a mooring array beneath the swaths of SWOT Cal/Val south of New Caledonia, an internal tide (IT ...

A Global View on Internal Tides

Russian Journal of Earth Sciences
This is a review paper on generation of internal tides in the global ocean based on literature data and publications of the author. Energy fluxes of semidiurnal internal tide generation over submarine ridges were estimated based on modeling and ...

Tidal Mixing on the Antarctic Continental Slope Enhances Ocean Heat Transport With Implications for Sea Ice

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Ocean microstructure measurements collected during three austral summers (2023–2025) along the Antarctic continental slope off Dronning Maud Land show enhanced subsurface mixing. Mean turbulent dissipation between 100 and 800 m depth is an order of magnitude higher than in the open ocean, with an extreme event reaching 3×10−6 $3\times 1{0}^{-6}

Propagating Internal‐Tide‐Induced Wave Stresses Resolve Discrepancies in Ocean Surface Tide Energetics

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Ocean tides are a major energy reservoir in Earth's climate system, yet global tide models systematically fail to reproduce observed tidal energetics. This limitation arises because existing models do not adequately represent how tide‐generated internal waves in the deep ocean regulate ocean tide energy, accounting only for their initial ...

Tidal forcing, energetics, and mixing near the Yermak Plateau [PDF]

Ocean Science, 2015
The Yermak Plateau (YP), located northwest of Svalbard in Fram Strait, is the final passage for the inflow of warm Atlantic Water into the Arctic Ocean. The region is characterized by the largest barotropic tidal velocities in the Arctic Ocean.
