Internal gravity waves occur in the atmosphere and oceans as a result of their internal density stratification. In the atmosphere, the flow is sometimes visualized naturally by rows of cloud bands, condensation regions near the wave crests. In the oceans, they have excited intense interest because of their strong effects on acoustic propagation. To a fluid mechanician, they offer a beautiful array of phenomena, mostly as a consequence of their anisotropy (the restoring force in the oscillation, gravity, acts only vertically). These waves can be...
