High-Frequency Components of Ocean Waves and Their Relation to the Aerodynamic Roughness
High-Frequency Components Aerodynamic Roughness Ocean Waves
2009/4/2
Ocean waves of high frequency (from about 10 to 200 rad sec−1) were observed by means of a thin capacitance-type wave gage. The representative rms height, hp, of the sea-surface irregularities a...
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...
Variation of Bulk-Derived Surface Flux, Stability, and Roughness Results Due to the Use of Different Transfer Coefficient Schemes
Bulk-Derived Surface Flux Transfer Coefficient Schemes
2009/1/15
Ten published bulk transfer coefficient schemes are used with more than 2600 sets of shipboard observations made in the North Atlantic at Ocean Station C over a one-year period. Using the same input d...
Effective Roughness Length for Turbulent Flow over a Wavy Surface
Roughness Length Turbulent Flow Wavy Surface
2009/1/4
A two-equation turbulence model is used to calculate the effective roughness length for two-dimensional turbulent flow over small amplitude, wavy surface topography. The governing equations are solved...
Residual Circulations Due to Bottom Roughness Variability under Tidal Flows
Tidal Flows nonlinear interaction residual circulation flows
2008/12/16
Tidal flows over irregular bathymetry are known to produce residual circulation flows due to nonlinear interaction with gradients of depth. Using the depth-averaged vorticity equations, the generation...
On the Dependence of Sea Surface Roughness on Wind Waves
Sea Surface Roughness Wind Waves
2008/10/27
The influence of wind waves on the momentum transfer (wind stress) between the atmosphere and sea surface was studied using new measured data from the RASEX experiment and other datasets compiled by D...
Simulation of the Wind-Forced Near-Surface Circulation in Knight Inlet: A Parameterization of the Roughness Length
Wind-Forced Near-Surface Circulation Knight Inlet Roughness Length
2008/7/11
Month-long observations of along-channel velocity made close to the surface of Knight Inlet are used with a numerical model to estimate the roughness length z0 on the water side of the air–sea interfa...
Influence of Bottom Friction on Sea Surface Roughness and Its Impact on Shallow Water Wind Wave Modeling
Bottom Friction Sea Surface Roughness Shallow Water Wind Wave Modeling
2008/7/1
Using a selected subset of the measured data obtained in shallow waters near Vindeby, Denmark, during RASEX (Risø Air–Sea Experiment), the role of bottom friction dissipation in predicting wind...
Phase Distribution of Small-Scale Ocean Surface Roughness
Phase Distribution Small-Scale Ocean Surface
2008/6/20
Remote sensing is becoming an important tool for oceanographic research. As the resolution of remote sensors is becoming comparable to the wavelength of dominant ocean surface waves, the usual assumpt...
Bed-roughness effects on boundary-layer turbulence and consequences for odor-tracking behavior of blue crabs (Callinectes sapidus)
boundary-layer turbulence odor-tracking behavior of blue crabs
2014/4/22
We employed laser-induced fluorescence (LIF) measurements of odorant plume structure and behavioral
observations to examine how turbulence affects the three-dimensional structure of odorant plumes an...
Effects of surface roughness and oscillatory flow on the dissolution of plaster forms: Evidence for nutrient mass transfer to coral reef communities
surface roughness oscillatory flow dissolution of plaster forms nutrient mass transfer coral reef communities
2014/5/8
We dissolved plaster forms in seawater to examine the effects of surface roughness and flow conditions on masstransfer rates. Plaster blocks with varying roughness were dissolved under both steady and...
