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.

However, the time-lag differences motivate the potential to investigate vertical propagation of atmospheric gravity waves starting at the surface due to the cooling and subsequent re-warming signal.
Gravity waves (GWs) are generated by convection, topography, instability, tropical cyclones, and various adjustment processes in the atmosphere [49, 50].

If we want to find wave field near the caustic, then it is necessary to use special approximation of the solution, and in the paper a modified ray method is proposed in order to build uniform asymptotic expansion of integral forms of the internal gravity wave field.
The presence of the free surface allows the propagation of gravity waves at the speed of [square root of gh].
From this one can hypothesize that ordinary gravity waves (the waves that compose the standing wave) move at near infinite velocities since its frequencies would be so high coming from an infinitesimally small portion of matter.

VVCARDUCCI could never quite shake off Gravity Wave in the opening maiden at Salisbury and, despite being done at 1.03, she was worn down on the line.
