A regional model of the semidiurnal internal tide on the Australian North West Shelf [PDF]

Journal of Geophysical Research: Oceans, 2001
A fully three‐dimensional nonlinear primitive equation model is applied to a study of the semidiurnal internal tide on the Australian North West Shelf, a region of strong barotropic and baroclinic tide. The model shows a significant internal tide over most of the continental slope region, predominantly between 100‐ and 1000‐m depths.

Generation of Submesoscale Vortices by Tidal Currents Near a Water Headland

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract This study investigates the generation of high‐frequency, submesoscale vortices by baroclinic tidal flow near a coastal headland off southeast Korea. Using a combination of shipboard surveys and a triangular array of three bottom‐mounted acoustic Doppler current profilers, we characterize the structure and dynamics of these motions.

Drivers of F‐Region Ionosphere Tidal Variability Caused by the Madden Julian Oscillation: Separating E‐Region Dynamo and Field‐Aligned Wind Effects

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The Madden–Julian Oscillation (MJO), a recurring intraseasonal (30–96 days) disturbance in the troposphere, strongly influences the E‐region and F‐region ionosphere through its modulation of atmospheric tides. Among these, the diurnal eastward wave number 3 (DE3) tide, driven by MJO‐modulated latent heating, carries MJO signals upward into the

Cold Pool Formation Over the Taiwan Bank Driven by Shoaling Internal Tides

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Cold, saline, and chlorophyll‐rich surface waters are frequently observed over the Taiwan Bank in the southern Taiwan Strait, forming a distinct feature referred to as the Green–Cold Pool (GCP). Despite its ecological importance, the physical mechanisms sustaining this cold pool remain unclear.

A global summary of seafloor topography influenced by internal-wave-induced turbulent water mixing [PDF]

Ocean Science
Turbulent water motions are important for the exchange of momentum, heat, nutrients, and suspended matter, including sediments in the deep sea. The motions occur in a deep sea that is generally stably stratified in density.

Internal Wave Climates of the Philippine Seas [PDF]

Oceanography, 2011
Internal wave measurements from moorings and profiling floats throughout the Philippine Archipelago, collected as part of the Office of Naval Research Philippine Straits Dynamics Experiment, reveal a wealth of subsurface processes, some of which have not

Semidiurnal M₂ internal tides in the Indo‐Australian Basin

Geophysical Research Letters, 2006
Clear signals of internal tide propagation are found at the semidiurnal M2 frequency in the eastern South Indian Ocean over the abyssal plain of the Indonesian Australian Basin. We find a spatially and temporally coherent internal tide with phase propagation estimated from satellite altimetry suggesting generation along the Indonesian Archipelago and ...

Vertical Structure of Semidiurnal Internal Tide in Uchiura Bay, the Head of Suruga Bay.

Oceanography in Japan, 2002
駿河湾奥内浦湾での半日周期内部潮汐の鉛直構造を調べるため,2000年夏季に水深98mの地点で水温と流速の係留観測を実施した。各層の水温記録から求めた鉛直変位の振幅は上層と中層で大きく,位相は下層に向かいやや遅れる傾向を示した。東西流の振幅は上層と下層で大きく,躍層を境に上下で位相が逆転していた。南北流の振幅は中層で極大をとり,下層に向かい位相が遅れていた。力学モード解析により,鉛直変位と東西流は第1モードが卓越し,両者は定在波の位相関係にあることが分かった。しかし,南北流は第2モードが卓越し,東西流とは異なる波に伴う流れであることを示唆した。次に,半日のバンドパスフィルターを施した記録を用い,力学第1モードの東西流と各層の南北流との相関を調べた。下層で東向きの第1モードの流れに対し ...

Generation of internal waves by a semidiurnal barotropic tide in the Mid-Atlantic ridge area

Physical Oceanography, 1996
Internal waves occurring in the specific Mid-Atlantic ridge area as a result of the impinging of a barotropic tide are studied in the terms of the linear theory for surface waves. The ocean is assumed to be double-layered, with a tidal wave running onto it at an arbitrary angle.
