Abstract

The surface perturbation in a viscous stratified liquid is investigated in a 2D formulation. Expressions for the dynamics of periodic surface motion and the fine-scale structure of currents are derived. Distributions of the wave and ligament components of density, density gradients, and pressure are constructed. A fine structure accompanying the wave component of the flow in physically measurable variables is identified.
