Fr.: onde de gravité
1) A wave that forms and propagates at the free → surface
of a body of → fluid
after that surface has been disturbed and the fluid particles
have been displaced from their original positions.
The motion of such waves is controlled by the restoring force of gravity rather
than by the surface tension of the fluid.
internal gravity wave (IGW)
mowj-e gerâni-ye daruni
Fr.: onde de gravité interne
A wave generated inside a density-stratified fluid under the influence of → buoyancy forces. Known also as → gravity wave or internal wave.
