Effects of Long Waves on Wind-Generated Waves

Wind-generated water waves: two overlooked mechanisms?

From research on stratospheric dynamics there has emerged what might prove to be some useful fresh ideas about the problem of water-wave generation by wind. As pointed out in an earlier contribution (1993), water waves can be systematically amplified by two irreversible, ratchet-like mechanisms that depend on spatio-temporal inhomogeneities, such as wind gustiness and wave groupiness. Neither m...

Generalized Stability Analysis of Wind Generated Surface Water Waves

The shear instability mechanism for generation of surface water waves (Miles 1957) is re-examined in light of the nonnormality of the underlying linear operator. The associated eigenproblem and adjoint eigenproblem are solved numerically and a clarification to previous perturbation solutions of the eigenproblem discussed. The optimal excitation problem is solved in the asymptotic limit t → ∞ an...

Effects of radio waves on male fertility

In recent years, male fertility has changed due to the effects of environmental, health and lifestyle factors and the infertility rate has increased, to the extent that male fertility may be affected by extreme heat, exposure to pesticides, radiation, substances Changes in radioactivity, lifestyle, stress and occupation. In the environment, there are ionizing and non-ionizing rays whose effect...

Turbulent flow structure in experimental laboratory wind-generated gravity waves

Weak turbulent approach to the wind-generated gravity sea waves

We performed numerical simulation of the kinetic equation describing behavior of an ensemble of random-phase, spatially homogeneous gravity waves on the surface of the infinitely deep ocean. Results of simulation support the theory of weak turbulence not only in its basic points, but also in many details. The weak turbulent theory predicts that the main physical processes taking place in the wa...
