Nonlinear internal waves in the South China Sea: Observation of the conversion of depression internal waves to elevation internal waves
[1] The conversion of depression nonlinear internal solitons to elevation internal waves has been observed twice at the South China Sea continental shelf break. Shipboard X-band radar, tow-yo CTD, ADCP and high frequency acoustic flow visualization of the process are presented. The data focuses on up slope propagation of depression internal solitons from a water depth of 264 m to a water depth ...
متن کاملNonlinear internal waves in the upper atmosphere
This paper considers the large-scale dynamics generated in the upper atmosphere by the destabilization of a linear internal gravity wave and its eventual restabilization through nonlinear processes into a coherent pattern. The assumption of a strongly dissipative medium is relevant to wave propagation in the thermosphere range above 100 km. A parametric instability analysis is carried out invol...
متن کاملSeafloor Pressure Measurements of Nonlinear Internal Waves
Highly resolved pressure measurements on the seafloor over New Jersey’s continental shelf reveal the pressure signature of nonlinear internal waves of depression as negative pressure perturbations. The sign of the perturbation is determined by the dominance of the internal hydrostatic pressure (pWh) due to isopycnal displacement over the contributions of external hydrostatic pressure ( 0g H; H ...
متن کاملNonlinear Dynamics of Hydrostatic Internal Gravity Waves
Stratified hydrostatic fluids have linear internal gravity waves with different phase speeds and vertical profiles. Here a simplified set of partial differential equations (PDE) is derived to represent the nonlinear dynamics of waves with different vertical profiles. The equations are derived by projecting the full nonlinear equations onto the vertical modes of two gravity waves, and the result...
متن کاملTranscritical generation of nonlinear internal waves in the presence of background shear flow
While the occurrence of large amplitude internal waves in the Earth’s natural bodies of water is widely documented, the generation of these waves remains an active area of exploration. We discuss numerical simulations of transcritical flows of a density strat ified fluid with a dual focus on the role of a background shear current and transitions of the background current from super to subcriti...
