Laboratory Modeling and Theoretical Studies of Wave Processes in the Ocean. Part2, First Stage Results

摘要

The results of theoretical studies and laboratory modeling of waves and vorticesin the upper ocean are presented. In particular, structure of surface wave contrasts due to the inhomogeneous flow around a dipole-type obstacle, wave drag in a stratified fluid in the presence of a critical layer, and vortex pair motion in the presence of a pyncnocline are calculated. The experiments deal with different aspects of propagation of strong (nonlinear) surface gravity waves: self-steepening of wave packets and amplitude dependence of phase velocities in traveling and standing (counterpropagating) waves. These results are believed to be important to better understand the processes in the upper ocean to be observed by remote sensing methods.
