Internal Gravity Waves
Ocean waves move due to gravity: the water at crests is heavier than the air surrounding it and so it falls, overshoots its equilibrium position and then at a trough feels an upward restoring force. The same phenomena occurs below the ocean surface. Cold water lifted upward into warmer surroundings will feel a downward buoyancy force and downwarddisplaced warm water will feel an upward buoyancy...
متن کاملOverturned internal capillary-gravity waves
A vortex sheet formulation of irrotational, incompressible Euler flow is used to compute periodic traveling waves at the interface between two constant-density, two-dimensional fluids, including waves with overturned crests. Branches of traveling waves are computed via numerical continuation, which are jointly continuous in the physical parameters: Bond number, Atwood number and mean shear. Glo...
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 کاملNonlinear 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 کاملFrom Topographic Internal Gravity Waves to Turbulence
Internal gravity waves are a key process linking the large-scale mechanical forcing of the oceans to small-scale turbulence and mixing. In this review, we focus on internal waves generated by barotropic tidal flow over topography. We review progress made in the past decade toward understanding the different processes that can lead to turbulence during the generation, propagation, and reflection...
