gravity wave

[′grav·əd·ē ‚wāv]
(fluid mechanics)
A wave at a gas-liquid interface which depends primarily upon gravitational forces, surface tension and viscosity being of secondary importance.
A wave in a fluid medium in which restoring forces are provided primarily by buoyancy (that is, gravity) rather than by compression.

Height profiles of atmospheric gravity waves from a coordinated observation.
Oscillations in wind velocity due to atmospheric gravity waves appear at all altitudes, as shown in Fig.
These above results suggest that the turbulent layer in the mesosphere is caused by the breaking of atmospheric gravity waves.
Frequency and vertical wave number spectra of atmospheric gravity waves
Atmospheric gravity waves are seldom monochromatic in the real atmosphere.
First, we introduce a semi-empirical model for the frequency spectrum of atmospheric gravity waves.
A theory that fully explains the spectra of atmospheric gravity waves has not yet been developed, but, there has been some explanation of the form of the high wave number portion of the vertical wave number spectra.
40) The GPS-RO technique thus provides a unique opportunity to observe the global morphology of atmospheric gravity waves, by taking advantage of superior vertical resolutions of approximately 200 m.
The temperature data obtained via GPS RO offers outstanding altitude resolution, which makes it possible to analyze medium-scale temperature disturbances in the stratosphere due to atmospheric gravity waves.
Therefore, in the equatorial region, cumulous convection appears to be an important excitation mechanism for atmospheric gravity waves.
They in turn excite atmospheric gravity waves, which propagate upward carrying momentum and energy.
