Abstract

In this work, we consider the mathematical theory of wind generatedwater waves. This entails determining the stability properties ofthe family of laminar flow solutions to the two-phase interfaceEuler equation. We present a rigorous derivation of the linearizedevolution equations about an arbitrary steady solution, and, usingthis, we give a complete proof of the instability criterion of Miles [16]. Our analysis is valid even in thepresence of surface tension and a vortex sheet (discontinuity in thetangential velocity across the air–sea interface). We are thusable to give a unified equation connecting the Kelvin–Helmholtz andquasi-laminar models of wave generation.
