Short Surface Waves With Growth and Dissipation

  title={Short Surface Waves With Growth and Dissipation},
  author={Jerome A. Smith},
  journal={Journal of Geophysical Research},
The modulation of surface waves by larger-scale flows is central to many forms of remote imaging of the sea surface yet is an incompletely understood process. An excellent example is the modulation of short waves by long ones (e.g., by swell). Observed modulations are of the order of 10 times the long-wave steepness, decrease with both the long-wave frequency and windspeed, and have stable phase, with maximum short-wave amplitudes just forward of the long-wave crests. Assuming a balance between… Expand
Modulation of Short Wind Waves by Long Waves
The behavior of short surface waves (wavelength less than a meter or so) riding on longer wind waves or swell has sparked interest for several decades now. In the problem as posed here, the energeticExpand
On Growth Rate of Wind Waves: Impact of Short-Scale Breaking Modulations
AbstractThe wave generation model based on the rapid distortion concept significantly underestimates empirical values of the wave growth rate. As suggested before, inclusion of the aerodynamicExpand

In this paper we develop a two-scale model of sea-surface roughness, in which for the first time the randomness of both long and short waves is taken fully into account. The model includesExpand
On the cascade mechanism of short surface wave modulation
Abstract. Modulation of short surface ripples by long surface or internal waves by a cascade mechanism is considered. At the first stage, the orbital velocity of the long wave (LW) adiabaticallyExpand
Observation of hydrodynamic modulation of gravity‐capillary waves by dominant gravity waves
[1] Accurate evaluation of the hydrodynamic modulation of short wind waves by dominant gravity waves is needed for various applications of microwave radar remote sensing of the ocean surface. SuchExpand
Observed Variability of Ocean Wave Stokes Drift, and the Eulerian Response to Passing Groups
Waves and currents interact via exchanges of mass and momentum. The mass and momentum fluxes associated with surface waves are closely linked to their Stokes drift. Both the variability of the StokesExpand
Wave–Current Interactions in Finite Depth
The energy, momentum, and mass-flux exchanges between surface waves and underlying Eulerian mean flows are considered, and terms in addition to the classical wave “radiation stress” are identified.Expand
Evolution of a gravity wave spectrum through a current gradient
Transformation of a wind wave spectrum through a region of nonuniform current is investigated. It is shown how an evolution equation for the spectral action can be arrived at by the scaling argumentsExpand
Microwave backscatter from the sea surface: Bragg scattering by short gravity waves
Resonant Bragg scattering forms the basis for the composite or dual-scale model for microwave backscatter from the sea surface. The scatterers are short surface waves that are spatially resonant withExpand
Dissipation source terms and whitecap statistics
Abstract Whitecaps are the main sink of wave energy and their occurrence has been related to the steepness of the waves. Recent parameterizations of the wave dissipation in numerical models are basedExpand


The Interaction between Long and Short Wind-Generated Waves
The interaction of wind-induced short (capillary) and long (gravity) surface waves of disparate scales is analyzed with the use of an expansion procedure accounting for the lowest-order effects ofExpand

Abstract Short, dissipative, surface waves superposed on longer waves cause a growth of the long wave momentum Ml at a ratewhere kl, al are the amplitude and wavenumber of the long waves, so thatExpand
Wave breaking in the presence of wind drift and swell
Wind, blowing over a water surface, induces a thin layer of high vorticity in which the wind stress is supported by molecular viscosity; the magnitude of the surface drift, the velocity differenceExpand

Recent observations of the growth of sea waves under the action of wind have established that the rate of growth is several times greater than has yet been accounted for. In this paper a newExpand
