Interaction Features of Internal Wave Breathers in a Stratified Ocean
Fluids, 2020 Oscillating wave packets (breathers) are a significant part of the dynamics of internal gravity waves in a stratified ocean. The formation of these waves can be provoked, in particular, by the decay of long internal tidal waves. Breather interactions can

A Model Sensitivity Study of Ocean Surface Wave Modulation Induced by Internal Waves
Earth and Space Science, 2022 Nonlinear internal waves are an upper ocean phenomenon that drives horizontal surface current gradients, which in turn modulate ocean surface waves. Under certain conditions, this wave‐current interaction creates ocean surface roughness heterogeneity, in

Fluctuations of radio occultation signals in sounding the Earth's atmosphere [PDF]
Atmospheric Measurement Techniques, 2018 We discuss the relationships that link the observed fluctuation spectra of the amplitude and phase of signals used for the radio occultation sounding of the Earth's atmosphere, with the spectra of atmospheric inhomogeneities.

Buoyancy waves in Pluto's high atmosphere: Implications for stellar occultations [PDF]
, 2008 We apply scintillation theory to stellar signal fluctuations in the high-resolution, high signal/noise, dual-wavelength data from the MMT observation of the 2007 March 18 occultation of P445.3 by Pluto.

Scalar and Tensor Inhomogeneities from Dimensional Decoupling [PDF]
, 1996 We discuss some perturbative techniques suitable for the gauge-invariant treatment of the scalar and tensor inhomogeneities of an anisotropic and homogeneous background geometry whose spatial section naturally decomposes into the direct product of two ...

The instability of internal gravity waves to localised disturbances [PDF]
Annales Geophysicae, 1995 The instability of an internal gravity wave due to nonlinear wave-wave interaction is studied theoretically and numerically. Three different aspects of this phenomenon are examined. 1.

Gravity wave propagation in the realistic atmosphere based on a three-dimensional transfer function model [PDF]
Annales Geophysicae, 2007 In order to study the filter effect of the background winds on the propagation of gravity waves, a three-dimensional transfer function model is developed on the basis of the complex dispersion relation of internal gravity waves in a stratified ...

A Brief Overview of Gravity Wave Retrieval Techniques From Observations
Frontiers in Astronomy and Space Sciences, 2022 Atmospheric gravity waves (GWs) are important in driving the middle and upper atmosphere dynamics on Earth. Here, we provide a brief review of the most common techniques of retrieving gravity wave activity from observations.
