gravity wave

n.
1. A wave induced in a fluid, especially the ocean or atmosphere, by the interaction of gravity with other forces on the motion of the fluid.
2. A gravitational wave. Not in technical use.

gravity wave

n
1. (General Physics) a wave propagated in a gravitational field, predicted to occur as a result of an accelerating mass
2. (General Physics) a surface wave on water or other liquid propagated because of the weight of liquid in the crests

An atmospheric gravity wave excited at a low altitude propagates upward and reaches an altitude at which its horizontal phase speed becomes equal to the horizontal background wind speed in the direction of propagation.

Atmospheric gravity waves were a secondary focus and multiple radiosonde flights were added to the schedule to collect necessary datasets in an attempt to answer the question of whether eclipse-induced stratospheric gravity waves can be detected with radiosonde data.
This project will study a class of atmospheric waves (known as atmospheric gravity waves) and associated travelling ionospheric disturbances at high latitudes, along with the possible connections between this wave activity and geomagnetic activity.

Atmospheric gravity waves resemble waves produced in water when a floating object is pushed down and released.
According to Yuter, "these waves cause up-and-down motions in the atmosphere, akin to a boat bobbing on the ocean." The scientists believe that at nighttime, winds moving offshore from the southwestern coast of Africa interact with stable air over the ocean, forming the atmospheric gravity waves. The waves travel westward through the cloud field and trigger mixing and cloud evaporation.

A new study has found that atmospheric gravity waves that emanate from the eyewall of hurricanes may be an indicator of a storm's magnitude--a finding that potentially provides a valuable new method of estimating peak hurricane wind speeds from remote locations.
