The role of Lagrangian drift in the generation of surface waves by wind
L. R. Seitz, Mara A. Freilich, Nick Pizzo
A nonlinear stability analysis entirely in the Lagrangian frame is conducted, revealing the fundamental role of the wave-induced mean flow in modifying further wave growth and prov…
Deep flows transmitted by forced surface gravity waves
Nick Pizzo, Gregory L. Wagner
We examine a two-dimensional deep-water surface gravity wave packet generated by a pressure disturbance in the Lagrangian reference frame. The pressure disturbance has the form of…
Momentum, energy and vorticity balances in deep-water surface gravity waves
Aidan Blaser, Raphaël Benamran, A. Bia Villas Bôas +2
The particle trajectories in irrotational, incompressible and inviscid deep-water surface gravity waves are open, leading to a net drift in the direction of wave propagation common…
Exact planetary waves and jet streams
Nick Pizzo, Rick Salmon
We investigate exact nonlinear waves on surfaces locally approximating the rotating sphere for two-dimensional inviscid incompressible flow. Our first system corresponds to a beta-…
