INTERNAL GRAVITY WAVES The study of internal gravity waves provides many challenges: they move along interfaces as well as in fully three-dimensional space, and they do so at relatively Chapter 8 Internal Gravity Waves: Basics Supplemental reading: Holton (1979), sections 7.1-4 Houghton (1977), sections 8.1-3 Pedlosky (2003) Lindzen (1973) Atmospheric waves (eddies) are important in their own right as major com­ ponents of the total circulation. They are also major transporters of energy and momentum. For a medium to propagate a disturbance as a wave there must be a ... L4: Internal Gravity Waves T.M. Rogers Waves, Instabilities and Turbulence in GAFD, 8-14 July 2019 Cargese The study of internal gravity waves provides many challenges: they move along interfaces as well as in fully three-dimensional space, at relatively fast temporal and small spatial scales, making them difficult to observe and resolve in weather and climate models. Solving the equations describing their evolution poses various mathematical challenges associated with singular boundary value ... Internal wave, a type of gravity wave that occurs on internal "surfaces" within ocean waters. These surfaces represent strata of rapidly changing water density with increasing depth, and the associated waves are called internal waves. Internal waves manifest themselves by a regular rising and It is shown here that many or most of the observational data may be interpreted on the basis of a single physical mechanism, namely, internal atmospheric gravity waves. A comprehensive picture is envisaged for the motions normally encountered, in which a spectrum of waves is generated at low levels of the atmosphere and propagated upwards. The ... These waves may be unstable through parametric instability, which results in turbulence and mixing. After a brief review of the main properties of internal gravity waves, we show how the parametric instability of a monochromatic internal gravity wave organizes itself in space and time, using energetics arguments and a simple kinematic model.
