Internal Wave
Internal waves are gravity waves that oscillate within, rather than on the surface of, a fluid medium. They are one of many types of wave motion in stratified fluids (another example being Lee waves). A simple example is a wave propagating on the interface between two fluids of different densities, such as oil and water. Internal wave motions are ubiquitous in both the ocean and atmosphere, where they create wave clouds. Nonlinear solitary internal waves are called solitons.

Famous quotes containing the words internal and/or wave:
“What makes some internal feature of a thing a representation could only its role in regulating the behavior of an intentional system.”
—Daniel Clement Dennett (b. 1942)
““Speaking of contraries, see how the brook
In that white wave runs counter to itself.
It is from that in water we were from
Long, long before we were from any creature.”
—Robert Frost (1874–1963)
