We examine the long-term evolution of a random wind wave field generated by constant forcing, by comparing numerical simulations of the kinetic equation and direct numerical simulations (DNS) of the dynamical equations. While the integral characteris... Read More about Effects of finite non-Gaussianity on evolution of a random wind wave field..

Spectral evolution of weakly nonlinear random waves: kinetic description versus direct numerical simulations (2018)
Journal Article

Kinetic equations are widely used in many branches of science to describe the evolution of random wave spectra. To examine the validity of these equations, we study numerically the long-term evolution of water wave spectra without wind input using th...

The existing wave turbulence paradigm assumes, in particular, a proximity to stationarity and spatial homogeneity of the wave field under consideration, which is often violated in nature. In this review, we outline a new theoretical approach free fro... Read More about Towards a New Picture of Wave Turbulence.
