In this letter we show how the nonlinear evolution of a resonant triad depends on the special combination of the modesâ€™ phases chosen according to the resonance conditions. This phase combination isâ€¦ (More)

A novel discrete model (D model) is presented describing nonlinear wave interactions in systems with small and moderate nonlinearity under narrow frequency band excitation. It integrates in a singleâ€¦ (More)

We suggest a way of rationalizing intraseasonal oscillations of Earth's atmospheric flow as four meteorologically relevant triads of interacting planetary waves, isolated from the system of all ofâ€¦ (More)

Traditionally resonant interactions among short waves, with large real wavenumbers, were described statistically and only a small domain in spectral space with integer wave-numbers, discreteâ€¦ (More)

A model of laminated wave turbulence is presented. This model consists of two co-existing layers one with continuous wavesâ€™ spectra, covered by KAM theory and Kolmogorov-like power spectra, and oneâ€¦ (More)

It is well known that the dynamics of a Hamiltonian system depends crucially on whether or not it possesses nonlinear resonances. In the generic case, the set of nonlinear resonances consists ofâ€¦ (More)

Different dynamics, described by kinetic equation and clipping method is shown as well as a role of approximate resonances in wave turbulence theory. Applications of clipping method are sketched forâ€¦ (More)

The influence of an underlying current on three-wave interactions of capillary water waves is studied. The fact that in irrotational flow resonant three-wave interactions are not possible can beâ€¦ (More)

The model of laminated wave turbulence presented recently unites both types of turbulent wave systems-statistical wave turbulence (introduced by Kolmogorov and brought to the present form by numerousâ€¦ (More)

The structure of discrete resonances in water wave turbulence is studied. It is shown that the number of exact 4-wave resonances is huge (hundreds of millions) even in a comparatively small spectralâ€¦ (More)
