The Garrett and Munk spectrum describes the turbulence of ocean interior due to internal gravity waves. We use unique large scale Coriolis facility force by waves reproduce main features wave in a stratified fluid laboratory. A transition from weakly nonlinear strongly was indeed observed when increasing buoyancy Reynolds number.

A compressible, viscous and heat conducting fluid is confined between two parallel plates maintained at a constant temperature subject to strong stratification due the gravitational force. We consider asymptotic limit, where Mach number Froude are of same order proportional small parameter. show limit problem can be identified with Majda's model layered ``stack-of-pancake'' flow.

We present the results of a combined experimental and theoretical investigation of sedimentation in a stratified fluid. The theory of sedimentation in a homogeneous ambient is extended to include the influence of a spatially varying particle settling speed. The results of an experimental investigation of latex particles settling in a stably stratified salt water solution are reported. Density v...
