"Would you like to go to the North Pole?" With an emphatic and affirmative "Yes!," this middle-school science teacher found herself off on the adventure of a lifetime. In the summer of 2004, I spent s...
Barotropic tides generate energetic internal tides, smaller-scale
waves, and turbulence as they flow through Luzon Strait, between Taiwan and
the Philippines. Three-dimensional numerical simulatio...
The sun inputs huge amounts of heat to the ocean, heat that would stay near the ocean's surface if it were not mechanically mixed into the deep. Warm water is less dense than cold water, so that heate...
Examining Breaking Internal Waves on a Shelf Slope Using Numerical Simulations
Numerical Simulations Internal Waves

The influence of wave breaking on wave statistics for finite-depth random wave trains is investigated experimentally. This paper is to investigate the influence of wave breaking and water depth on the...
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,...
Numerical Simulation of Dam Breaking Using Smoothed Particle Hydrodynamics and Viscosity Behavior
meshless method smoothed particle hydrodynamics (SPH) dam breaking free surface flow
2011/9/9
Smoothed particle hydrodynamics (SPH) is a Lagrangian meshless particle method. It is one of the best method for simulating violent free surface flows in fluids and solving large fluid deformations. D...
Probability Distributions of Breaking Wave Heights Emphasizing the Utilization of the JONSWAP Spectrum
Breaking Wave Heights JONSWAP Spectrum
2009/3/7
An approximate determination has been made of the probability distribution function for breaking wave heights in the deep ocean. It was necessary to make simplifying assumptions of the joint distribut...
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...
Detection of Breaking Events in a Wind-Generated Wave Field
Wind-Generated Wave Field fetch-limited wave field wave breaking
2009/1/21
Measurements were made of the surface elevation of a fetch-limited wave field (fetch 7 km, wind speed about 6 m s−1). Good high-frequency response was attained by the use of a very thin, bare wi...
On the Fluid Dynamical Theory of Turbulent Gas Transfer Across an Air-Sea Interface in the Presence of Breaking Wind-Waves
Fluid Dynamical Theory Turbulent Gas Transfer Air-Sea Interface Breaking Wind-Waves
2009/1/20
It is shown that in order to describe the transfer of gases in the liquid near the air-sea interface, the vertical structure of three-dimensional small-scale turbulence in turbulent patches generated ...
Lateral Wave Breaking and “Shingle” Formation in Large-Scale Shear Flow
Lateral Wave Large-Scale Shear Flow “Shingle” Formation
2009/1/16
The temporal evolution of large amplitude quasi-geostrophic disturbances in a piecewise uniform potential vorticity flow is elucidated by numerical solutions of the “contour dynamica” equations. Later...
Breaking of wind-generated waves was studies in a laboratory tank. The critical surface slope and global wave steepness for inception of breaking were evaluated. Besides the frequency of occurrence, t...
