Internal wave Wikipedia

Internal waves are gravity waves that oscillate within a fluid medium rather than on its surface To exist the fluid must be stratified the density must change continuously or discontinuously with depth height due to changes for example in temperature and or salinity If the density changes over a small vertical distance as in the case of the thermocline in lakes and oceans or an
