Scattering of internal gravity waves
Internal gravity waves play a fundamental role in the dynamics of stably stratified regions of the atmosphere and ocean. In addition to the radiation of momentum and energy remote from generation sites, internal waves drive vertical transport of heat and mass through the ocean by wave breaking and …

Interference and resonance of internal gravity waves
Internal waves are propagating disturbances within stratified fluids, arising from a balance of gravity, buoyancy, and rotation. As well as being of fundamental scientific interest, they are ubiquitous in a variety of forms in the Earth's oceans, where they are responsible for driving vertical …

Nonlinear interactions among standing surface and internal gravity waves
… to measure the momentum transfer from surface to internal gravity waves in a nonlinear, resonant interaction. The interacting waves form triads for which σ1s - σ2s ± σI = 0 and κ1s - κ2s ± κI = 0; σj and κj being the frequency and wavenumber of the jth wave. In particular, the experiment is …

Experimental study of internal gravity waves over a slope
… wave tank to investigate the propagation of internal gravity waves up a sloping bottom in a fluid with constant Brunt-Vaisala frequency. Measurements of the wave motion in the fluid interior were primarily taken with electrical conductivity probes; measurements in the boundary layer were made …

Nonlinear interactions of internal gravity waves in a continuously stratified fluid
Internal gravity waves are buoyancy-driven oscillations which can arise in a density-stratified fluid. They exist throughout the oceans and atmosphere, the oceanic internal wavefield being sufficiently energetic for nonlinear effects to play an important role in the internal wave dynamics. …

Measurements and models of fine-structure, internal gravity waves and wave breaking in the deep ocean
… are interpreted in terms of thermocline-trapped internal wave modes in the presence of temperature and density fine-structure. Two turning-point uniformly valid asymptotic solutions to the internal wave equation are developed to describe the wave functions. Mode decay beyond the turning point in …

Instabilities of finite-width internal wave beams
Internal gravity waves are fundamental to the dynamics of density stratified fluids and the instability mechanisms by which these waves dissipate their energy are a potentially significant factor that underlies the distribution of energy and momentum in the natural environment. Recently, it has …

Tsunami monitoring using airglow imaging systems
Tsunamis generate internal gravity waves (IGWs) that propagate vertically into the atmosphere and can create detectable signatures in the ionosphere. These signatures have consistently been observed in the presence of a tsunami for over a decade in the total electron content and for over 5 years in …

ACCELERATED NOISE INTERFEROMETRY-BASED PASSIVE ACOUSTIC CHARACTERIZATION OF THE LITTORAL OCEAN
… acoustic propagation environment, e.g., due to internal gravity waves and tides. Using the data acquired in the Shallow Water 2006 experiment on the continental shelf off New Jersey, this thesis focuses on accelerating the noise-interferometry process by judiciously selecting periods where …

Formation of RAAN-Spread CubeSat Constellations Utilizing Onboard Low-Thrust Propulsion
Internal gravity waves are waves in the atmosphere caused by the interaction of air with differing buoyancy. This instability can cause weather phenomena to occur as the wave travels vertically and horizontally over large distances. To characterize these internal gravity waves, radio occultation …

Theoretical and experimental study of nonlinear internal gravity wave beams
… like the atmosphere and the oceans, support internal gravity waves due to the effect of buoyancy. This type of wave motion is anisotropic since gravity provides a preferred direction. As a result, a localized source oscillating at a frequency below the buoyancy frequency in a uniformly …

A global map of tidal dissipation over abyssal hills
Internal gravity waves are complex oscillations widely found in fluids exhibiting density stratification, such as the ocean. Such waves may be produced by tidal currents flowing over rough seafloors; they are then called internal tides. As they travel away from the seafloor, internal tides tend to …

Multi-Scale Atmospheric Dynamics of Extreme Saharan Dust Storms Resulting in Dust Transport Out of Africa to Iberia and the Atlantic
… jets, (d) hydraulic jumps, and (e) mesoscale internal gravity waves. Moreover, we also highlight that the interaction between moisture from the Eastern Atlantic and a residual convective cold pool could trigger unseasonably strong moist convection and a haboob on the Atlas' southern foothills. …
