Effects of surface wave breaking on the oceanic boundary layer
[1] Existing laboratory studies suggest that surface wave breaking may exert a significant impact on the formation and evolution of oceanic surface boundary layer, which plays an important role in the ocean‐atmosphere coupled system. However, present climate models either neglect the effects of wave breaking or treat them implicitly through some crude parameterization. Here we use a one‐dimensi...
متن کاملTurbulence and wave breaking effects on air-water gas exchange
We present an experimental characterization of the effects of turbulence and breaking gravity waves on air-water gas exchange in standing waves. We identify two regimes that govern aeration rates: turbulent transport when no wave breaking occurs and bubble dominated transport when wave breaking occurs. In both regimes, we correlate the qualitative changes in the aeration rate with corresponding...
متن کاملWeakly-compressible SPH and Experimental modeling of periodic wave breaking on a plane slope
Breaking waves have ability to transport large quantities of sediment and significant impact on coastal structures morphology. Hence, modeling of wave breaking is an important subject in coastal and marine engineering. In this research, the periodic wave breaking process on a plane slope is studied experimentally and numerically. Laboratory experiments were conducted to record water surface ele...
متن کاملA Study on Wave Breaking and Wave Interaction
This paper aims to apply two methods namely, Vortex Method and Higher Order Spectral Method to study the wave breaking and wave interaction. The breaking of shallow water gravity wave is performed using Vortex method, while the interaction between two gravity waves is carried out using Higher Order Spectral (HOS) method. In Vortex method an interface defined by a density or velocity discontinui...
متن کاملOn the occurrence of wave breaking
The practicality of common wave breaking criteria is reviewed. Video recordings of the sea surface taken from aboard R/P FLIP are used to extract breaking wave properties. The key quantity is Λ(c)dc, the length of breaking crests per unit area propagating with speeds in the range (c, c+ dc). Independent of wave field development, Λ(c) is found to peak at intermediate wave scales and to drop off...
