Gravity Wave
Weather
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.
Climate Change
Gravity wave (gravitational wave) A wave disturbance in which buoyancy (or reduced gravity) acts as restoring force on parcels displaced from hydrostatic equilibrium. There is a direct oscillatory conversion between potential and kinetic energy in the wave motion.
