Gravity wave (gravitational wave) A wave disturbance in which buoyancy (or reduced gravity) acts as restoring force on parcels displaced from hydrostatic equilibrium.
Gravity Wave
A wave created by the action of gravity on density variations in the stratified atmosphere. A generic classification for lee waves, mountains waves, and many other waves that form in the atmosphere.

Gravity wave
A perturbation along a vertical discontinuity, or gradient, which has gravity as its restoring force; for example ocean waves, storm surges.
acoustic-gravity wave"A wave disturbance with restoring forces that include buoyancy and the elastic compressibility of the fluid medium.
Also used for short duration mesoscale events such as a strong cold front, gravity wave, squall line, etc., lasting less than 2 hours and producing winds or gusts of 34 knots or greater.
