Reflection of Internal Gravity Waves by small Density Variations
Internal Gravity Waves small Density Variations
2009/4/3
The propagation of small-amplitude internal gravity waves through a finite layer of varying Brunt-Väisälä frequency is analyzed. A two-scale analysis is used and it is shown that the am...
