Revealing wave-wave resonant interactions in ocean wind waves
Davide Maestrini, Giovanni Dematteis, Alvise Benetazzo +1
Ocean wind waves are a fundamental manifestation of complex dynamics in geophysical fluid systems, characterized by a rich interplay between dispersion and nonlinearity. While line…
Mesoscale Eddy -- Internal Wave Coupling. III. The End of the Enstrophy Cascade and Maintenance of Gyre Scale Potential Vorticity Gradients
Kurt L. Polzin, Giovanni Dematteis
We assess a prognostic formulation of triple coherence relating to energy exchange between mesoscale eddies and the internal wavefield and compare with observations from the Sargas…
On the Wave Kinetic Equation in the presence of forcing and dissipation
Davide Maestrini, Daniele Noto, Giovanni Dematteis +1
The wave kinetic equation has become an important tool in different fields of physics. In particular, for surface gravity waves, it is the backbone of wave forecasting models. Its…
Spectral Transfers of Sign-Definite Invariants in Wave Turbulence
Nicholas R. Salvatore, Giovanni Dematteis, Yuri V. Lvov
We consider the spectral transfers of sign-definite invariants in general wave turbulence systems equipped with a wave kinetic equation. We develop a formalism to investigate and t…
Anomalous correlators, negative frequencies and non-phase-invariant Hamiltonians in random waves
Alberto Villois, Giovanni Dematteis, Yuri V. Lvov +2
We investigate a generic non-phase invariant Hamiltonian model that governs the dynamics of nonlinear dispersive waves. We give evidence that initial data characterized by random p…
