Kelvin wave propagation along straight boundaries in C-grid finite-difference models [PDF]

, 2013
Discrete solutions for the propagation of coastally-trapped Kelvin waves are studied, using a second-order finite-difference staggered grid formulation that is widely used in geophysical fluid dynamics (the Arakawa C-grid).

Stratospheric Sudden Warmings as Self-Tuning Resonances. Part II: Vortex Displacement Events

, 2011
Vortex displacement stratospheric sudden warmings (SSWs) are studied in an idealized model of a quasigeostrophic columnar vortex in an anelastic atmosphere.

Relative Sea‐Level Change, Tidal Evolution and Energy Dissipation Across the Patagonian Shelf Since the Last Glacial Maximum

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Tides play a key role in regulating shelf‐sea environments, influencing sediment dynamics, habitat distribution, long‐term carbon burial, coastal hazards, and water quality, with important socio‐economic consequences. Yet the long‐term evolution of shelf sea tides in response to sea‐level change remains poorly understood. We have developed the

Tidal Modulation of Waves Around the Aleutian Islands

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Forming a critical part of the North Pacific Great Circle Route, the narrow passes of the Aleutian Islands are considered among the United States' most treacherous waters for maritime navigation. This study investigates the tidal modulation of surface gravity waves throughout the archipelago using a high‐resolution, unstructured‐grid, coupled ...

Development of a Mesoscale‐ and Tide‐Resolving Ocean–Biogeochemistry Model for the Pacific: Tidal Enhancement of the Biological Carbon Pump

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract This study presents a new physical‐biogeochemical simulation of the Pacific Ocean that resolves mesoscale dynamics and explicitly includes tidal forcing. The primary objective is to develop and document a modeling framework that serves both as a detailed record of model configuration and forcing preparation, and as a reference for future ...

Impact of Intertidal Areas on Tidal Propagation in Tidally Dominated Estuaries. Part II: A Comprehensive Sensitivity Study

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract This is Part II of a two‐part theoretical study on the impact of intertidal areas on tides in tidally dominated estuaries. Part I developed an analytical model that resolves tidal motions in the channel and intertidal regions which are dynamically coupled through the water exchange between both regions.

Three‐Dimensional Characteristics and Dominant Forcing Mechanisms of Third Waves Generated by Nonlinear Near‐Inertial Wave and Internal Tide Interactions

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Nonlinear interactions between internal tides (ITs) and near‐inertial waves (NIWs) generate the “third waves” at frequencies corresponding to the sum of IT and NIW frequencies. The third waves drive oceanic energy cascade, yet under what conditions these waves are generated remain poorly quantified.

Novel Insights on Ocean Internal Waves: Quantitative Surface Manifestations and Upper Ocean Layer Displacements From the Surface Water Ocean Topography Mission (SWOT) Measurements

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission provides unprecedented high‐resolution simultaneous observations of both sea surface height anomalies and sea surface roughness. Specifically, it enables more precise analysis of strong internal waves. Off the Amazon Shelf, in the Indonesian Seas, and near the Mascarene Ridge, internal wave

On the β$$ \beta $$‐effect in the baroclinic instability of a continuously stratified atmosphere

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 774, January 2026 Part A.
We solve the quasi‐geostrophic equation numerically to analyze baroclinic instability in a continuously stratified atmosphere. On the β$$ \beta $$‐plane, deviations from classical models alter instability growth rates and modal structures, leading to the emergence of unstable lobes and a stable region at very large wavelengths.

Three Drivers of 21st‐Century Changes in Ocean Tides

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract Numerical model simulations are conducted to study the response of barotropic ocean tides to 21st‐century climate change, as manifested by sea level rise, increasing ocean stratification, and expanding Antarctic ice shelf cavities. Emphasis is placed on surface elevations, with projections of M2 ${\mathrm{M}}_{2}$, S2 ${\mathrm{S}}_{2}$, K1 ${\
