Nettetinternal wave beams are ubiquitous in the geophysical context. The usual pedagogical introduction to internal waves by oscillating a cylinder in a stratified fluid involves the generation of four wave beams in the pattern of Saint Andrews cross (Mowbray & Rarity 1967). Thorough studies of internal wave beams can be found in Voisin (2003). More- Nettetrole of internal gravity waves at transporting momentum from the lower to the upper atmosphere (e.g., Holton et al. 1995, McIntyre 1995). In the ocean, the main role of internal gravity waves is a vertical (diapycnal) mixing of heat and solutants occuring during wave breaking. In all these processes, internal gravity
