Waves in the Ocean
In this document we will discuss three types of waves: wind-driven waves, tides and tsunamis. When the wind blows on the surface of the ocean it produces ripples, waves, and swell. Gravitational forces (mostly from the moon and sun) plus centrifugal forces in the solar system produce tides. Tectonic forces such as earthquakes that cause vertical displacements of the ocean floor, submarine volca...
متن کاملCould waves mix the ocean?
A finite-amplitude propagating wave induces a drift in fluids. Understanding how drifts produced by many waves disperse pollutants has broad implications for geophysics and engineering. Previously, the effective diffusivity was calculated for a random set of small-amplitude surface and internal waves. Now, this is extended by Bühler & Holmes-Cerfon (J. Fluid Mech., 2009, this issue, vol. 638, p...
متن کاملComparative analysis on sensitivities of Love and Rayleigh waves
Love waves are generally less employed than Rayleigh waves in near-surface shear-wave (S-wave) investigations because acquiring S-wave data is not as easy as acquiring P-wave data. The dispersion of Love waves, however, is independent of Poisson’s ratio. This character can be the valuable basis to improve the S-wave velocity imaging. The sensitivity of earth properties to the dispersion curve o...
متن کاملLove waves in a piezoelectric layered structure
Consider a layer made of a m3m insulator crystal, with faces cut parallel to a symmetry plane. Then bond it onto a semi-infinite mm2 piezoelectric substrate. For a Xor Y -cut of the substrate, a Love wave can propagate in the resulting structure and the corresponding dispersion equation is derived analytically. It turns out that a fully explicit treatment can also be conducted in the case of a ...
متن کاملOcean Waves Workshop 2015
The present study investigates the conspicuous shortcomings of the whitecapping dissipation model implemented in WAM Cycle 4.5 [1], following the lead of the work of [2] and [3]. Its dependence on an overall wave steepness unavoidably yields systematic errors when more than one wave system is propagating. The distinctive, complex orography of the Catalan littoral and the fact that the Mediterra...
