Non-linear propagation of waves on two-dimensional liquid sheets
… behavior of antisymmetric as well as symmetric waves on a two-dimensional liquid sheet is studied, the effects of the surrounding fluid being taken into account. The non-linear Schrödinger equation governing the wave motion is derived by the method of multiple scales. Modulatory stability, …

Evolution of atmospheric baroclinic waves
The evolution of atmospheric baroclinic waves is investigated by a six-layer forced dissipative quasi-geostrophic $\beta$-plane channel model. In the control run, the model has: (i) a realistic zonal thermal forcing, (ii) a surface Ekman layer, a Newtonian cooling and an interior biharmonic …

Interference and resonance of internal gravity waves
Internal waves are propagating disturbances within stratified fluids, arising from a balance of gravity, buoyancy, and rotation. As well as being of fundamental scientific interest, they are ubiquitous in a variety of forms in the Earth's oceans, where they are responsible for driving vertical …

Harmonic generation and parametric excitation in a beam-plasma system
Harmonic generation by wave-wave and wave-particle interactions and parametric excitation of plasma and ion-acoustic waves by a beam-plasma instability are studied, theoretically and experimentally, in a cold beam-plasma system. The dispersion relations for plasma and ion-acoustic waves are …

Phase-resolved reconstruction and forecast of nonlinear irregular wave field based on direct numerical simulations
… reconstruction and forecast of ocean wave field based on measurements is of basic scientific interest and practical importance in ocean science and marine engineering. This capability aids and expands the use and interpretation of field and wave basin measurements, contributing to the …
