Abstract Long‐term observations of nonlinear internal waves in the South China Sea reveal seasonal to interannual variability. During two selected segments inverted echo sounder observations, tidal forcing Luzon Strait is almost identical, but observed amplitudes are very different. The effects Kuroshio and mesoscale eddies, reproduced by HYbrid Cooridnate Ocean Model (HYCOM) reanalysis simulation, then investigated. can enhance zonal tilt thermocline induce intruding flow Strait. segments,...
Abstract The modulation of anticyclonic subsurface‐intensified mode‐water eddies (MWEs) on the oceanic physical and biological responses to tropical cyclones (TCs) is investigated using satellite measurements, in situ observations numerical model outputs. Extreme cooling surface (4.2°C) mixed‐layer (2.3°C) observed a MWE, which can be remarkably stronger than those adjacent cyclonic eddy non‐eddy environments. special thermodynamic structure above lens MWEs, would favor TC‐induced...
The interaction between internal waves and submarine seamounts is three-dimensional (3D). In this work, we conduct laboratory experiments to investigate the role of seamount on reflection waves. Experimental results show that energy focused after phase wave front become curved. focusing region was nearly 2 times as scattering region. There a strong induced mean flow whose strength high 50% reflected wave. generated by variation velocity amplitude in both x axis y axis. These indicate from 3D...
Abstract The breaking of internal solitary waves (ISWs) over slope‐shelf topography induces energy dissipation and enhances mixing. In this work, high‐resolution, laboratory‐scale simulations are employed to investigate the instability mechanisms ISWs. We find that increasing nonhydrostatic pressure during deformation contributes an adverse gradient, which plunging flow for overturning. Shear convective instabilities trigger wave breaking. Wave‐induced vortexes induce strong shearing enhance...
Abstract The effects of Surface Solitary Waves (SSWs), which are created by Internal (ISWs), on optical imaging were investigated in this paper. We explored the connection between SSWs and images using simulations experiments with calm water surface conditions. An experimental platform was built a controlled laboratory environment where in‐situ wave data could be gathered simultaneously. different ISWs successfully observed. revealed inverse bright dark patterns for ISW types (depression or...
Abstract Reflection of the K 1 internal tides (ITs) in northern South China Sea (SCS) is investigated using a high‐resolution three‐dimensional numerical model. The simulated results indicate that westward ITs generated at Luzon Strait (LS) first impact continental slope SCS, and thereafter are reflected. There total 0.31 GW energy reflected, suggesting weak reflection considering 3.54 from LS. Two reflected beams revealed. southeast one more energetic can propagate across deep basin,...
Abstract The inversion of remote sensing signatures internal solitary waves (ISWs) can retrieve dynamic characteristics in the ocean interior. However, presence ubiquitous large‐amplitude ISWs poses challenges to commonly used weakly nonlinear methods for parameter retrieval. Through laboratory experiments, we establish a relationship between surface features and by imaging mechanism. results demonstrate that strong nonlinearity significantly influences retrieval ISWs, primarily manifested...
Internal solitary waves (ISWs) typically manifest as soliton or wave trains in the ocean. Previous studies have extensively explored dynamic properties of individual ISWs over topography. However, when distance between successive a train is less than certain threshold, interaction multiple with topography introduces mutual interference, leading to more complex dynamical process. Therefore, this study established numerical model based on OpenFOAM and analyzed processes two interacting...

However, a succedent research process may be impeded by dimensionality existing sensors. In present study, high-resolution sensor (VHTS) designed from cilium-shaped structure. The VHTS based on bionic principle and MEMS manufacturing technology. A systematic investigation conducted to improve meet stringent requirements in applications. measuring sensitivity...
We quantitatively study the relationship and differences between internal waves generated on two kinds of continental margin in laboratory. Experimental results show that steepness shelf break exerts a strong influence spatial structure margin. When oscillatory barotropic tide flows over with an abrupt is not resonant its slope, three energy rays are generated, while gentle break, only can be found waves. Moreover, we compare flux, width kinetic flux these find phases by interaction lag behind tide.
Abstract A series of laboratory experiments are performed to investigate the scattering low-mode internal tides at a continental shelf by varying criticality parameter and normalized topographic height independently. wide-range synchronized particle image velocimetery (PIV) measures velocity fields tides. Beams radiate from both break bottom slope, indicating that energy transfers low modes higher modes, which is verified modal decomposition. Energy also transferred harmonics, whose...
Optical remote sensing has been an important method to investigate the internal solitary wave (ISW). However, acquiring ISW amplitude from optical images most difficult problem. In this letter, a is proposed for inverting of ISW. A simulation platform established detect ISWs in laboratory, which offers corresponding and images. The experimental results show that characteristic parameters are changed with amplitude. relationship between them nonlinear related hierarchical structure. Hence,...
Internal solitary waves (ISWs) in the South China Sea (SCS) are considerably modulated by background currents. In this study, a three-dimensional high-resolution non-hydrostatic model is configured to investigate how Kuroshio influences generation and evolution of ISWs northern SCS. Three runs conducted, including one control experiment without two sensitivity experiments with different paths. Luzon Strait (LS), reduces westward baroclinic energy flux radiated into SCS, resulting weakened...
