Higher-order spectral analysis of nonlinear ocean surface gravity 'waves
Bispectral and trispectral analyses are used to detect secondary and tertiary wave components resulting from nonlinear interactions among largeamplitude ocean surface gravity waves in 8and 13-m water depths. Bispectra of bottom-pressure measurements indicate forced secondary waves at frequencies 2fp about twice the primary power spectral peak frequency fp. However, the interpretation of the bis...
متن کاملNonlinear Hyperbolic Surface Waves
We describe examples of hyperbolic surface waves and discuss their connection with initial boundary value and discontinuity problems for hyperbolic systems of PDEs that are weakly but not uniformly stable.
متن کاملDispersion Relations for Nonlinear Waves and Schottky Problem
An approach to the Schottky problem of specification of periods of holomorphic differentials on Riemann surfaces (or, equivalently, specification of Jacobians among all principaly polarized Abelian varieties) based on the theory of Kadomtsev Petviashvili equation, is discussed. Introduction. Dispersion relations for linear and nonlinear waves. One of the first exercises in a course of PDE is in...
متن کاملShock Waves and Compactons for Fifth-order Nonlinear Dispersion Equations
The following question is posed: to justify that the standing shock wave S−(x) = −signx = − { −1 for x < 0, 1 for x > 0, is a correct “entropy” solution of fifth-order nonlinear dispersion equations (NDEs), ut = −(uux)xxxx and ut = −(uuxxxx)x in R × R+. These two quasilinear degenerate PDEs are chosen as typical representatives, so other similar (2m+ 1)th-order NDEs with no divergence structure...
متن کاملOcean surface waves in an ice free Arctic Ocean
The retreating of Arctic ice edge implies that global ocean surface wave models have to be extended at high latitudes or even to cover the North Pole in the future. The obstacles for conventional latitude-longitude grid wave models to cover the whole Arctic are the polar problems associated with their Eulerian advection schemes, including the CFL restriction on diminishing grid-length towards t...
