人工智能 破浪 复杂性 模型预测 海洋气候模拟
2023/6/19
Waves break once they swell to a critical height, before cresting and crashing into a spray of droplets and bubbles. These waves can be as large as a surfer’s point break and as small as a gentle ripp...
Modeling Loads Caused by Breaking Waves Striking Vertical Walls
vertical breakwater breaking wave wave loads particle imaging velocimetry (PIV)
2011/9/9
Breaking waves can have tremendous destructive impact on vertical walls, yet they are poorly understood. By using particle imaging velocimetry (PIV) technology and high-precision pressure transducers,...
Wind Stress and Roughness Length over Breaking Waves
Wind Stress Roughness Length Breaking Waves
2009/3/7
The effects of surface wave breaking on the adjacent atmospheric boundary layer are examined. It is argued that the transition from aerodynamically smooth to rough flow in a neutral atmosphere corresp...
A method to evaluate the frequency of occurrence of breaking waves in deep water is developed based on the joint probability distribution of wave excursion and associated time interval for a non-narro...
Statistics of Breaking Waves Observed as Whitecaps in the Open Sea
Breaking Waves Whitecaps Open Sea
2009/1/10
Conventional observations of waves carried out with a buoy in open sea conditions were supplemented with simultaneous visual observations of whitecaps to identify breaking events in the buoy records. ...
Radar Returns from the Sea Surface—Bragg Scattering and Breaking Waves
Radar Returns Breaking Waves Sea Surface—Bragg Scattering
2009/1/6
Recent ideas on the structure of the equilibrium range of wind-generated ocean waves are applied to the question of radar backscattered returns from the sea surface. It is shown that the backscatterin...
Effect of Breaking Waves on the Transport of Heat and Vapor Fluxes from the Ocean
atmospheric surface layer high sea Transport
2008/12/19
One method of studying the complexities of the atmospheric surface layer over the ocean during high sea states is to consider the waves as moving drag objects for the wind. The study treats transport ...
Energy Dissipation by Breaking Waves
Energy Dissipation Breaking Waves field measurements
2008/12/16
Recent field measurements by Agrawal et al. have provided evidence of a shallow surface mixed layer in which the rate of dissipation due to turbulence is one to two orders of magnitude greater than th...
Estimates of Kinetic Energy Dissipation under Breaking Waves
Kinetic Energy Dissipation Breaking Waves
2008/12/9
The dissipation of kinetic energy at the surface of natural water bodies has important consequences for many Physical and biochemical processes including wave dynamics, gas transfer, mixing of nutrien...

Kinetic Energy Dissipation Breaking Waves
2008/12/3
It is noted that the results of recent experiments on the enhancement of turbulent kinetic energy (TKE) dissipation below surface waves can be stated as follows. TKE dissipation is enhanced by a facto...
Spectral Energy Balance of Breaking Waves within the Surf Zone
Spectral Energy Balance Breaking Waves Surf Zone
2008/7/3
The spectral energy balance of ocean surface waves breaking on a natural beach is examined with field observations from a cross-shore array of pressure sensors deployed between the shoreline and the o...
Free-Wave Energy Dissipation in Experimental Breaking Waves
Free-Wave Energy Dissipation Experimental Breaking Waves
2008/7/3
Several transient wave trains containing an isolated plunging or spilling breaker at a prescribed location were generated in a two-dimensional wave flume using an energy focusing technique. Surface el...
Bubbles Produced by Breaking Waves in Fresh and Salt Waters
Bubbles Produced Breaking Waves Fresh Salt Waters
2008/7/1
A greater volume of air is entrained by breaking waves to produce many more bubbles in salt, than in fresh, water. There are, however, little differences in their sizes. These results are consistent w...
