The plume of Mississippi and Atchafalaya River system (MARS) is normally confined to the continental shelf
and extends westward. During March 2010, while weather in North America was dominated by unu...
Nonlinear dynamics of wind waves:multifractal phase/time effects
Nonlinear dynamics of wind waves multifractal phase time effects
2009/11/16
In addition to the bispectral coherence method, phase/time analysis of analytic signals is another promising avenue for the investigation of phase effects in wind waves. Frequency spectra of phase flu...

2009/11/16
Asymmetry of wind waves was studied in laboratory tank tinder varied wind and fetch conditions using both bispectral analysis of wave records and third-order statistics of the surface elevation. It is...

2009/11/11
The coastal ocean may experience periods of fluctuating along-shelf wind direction, causing shifts between upwelling and downwelling conditions with responses that are not symmetric. We seek to unders...
Theoretical interpretation of fetch limited wind-drivensea observations
Theoretical interpretation fetch limited wind-drivensea observations
2009/11/11
We show that the results of major fetch limited field studies of wind-generated surface gravity waves on deep water can be explained in the framework of simple analytical model. The spectra measured i...
The results of theoretical and numerical study of the Hasselmann kinetic equation for deep water waves in presence of wind input and dissipation are presented. The guideline of the study: nonlinear tr...

stochastic stability regional ocean models uncertainty in wind forcing
2009/11/3
A shallow-water model was used to understand model error induced by non-Gaussian wind uncertainty. Although the model was simple, it described a generic system with many degrees of freedom randomized ...
Nonlinear momentum transfer from wind to wave has been studied on the basis of a perturbation expansion procedure. Two nonlinear effects are presented, namely the generation of higher harmonies of the...

Wind-Generated Current Phase Speed Wind Waves
2009/4/3
Measurements of drift were made in a wind and wave facility at different elevations below the mean water level. The drift profiles were obtained for reference wind speeds, Ur=3.1, 5.7 and 9.6 m sec...
Theoretical Aspects of Wind-Driven Currents in a Sea or Lake of Variable Depth with No Horizontal Mixing
Wind-Driven Currents Variable Depth with No Horizontal Mixing
2009/4/3
Steady-state wind-driven circulations in a basin of variable depth, with only vertical turbulent mixing, are considered. The geostrophic flow away from the coast is determined for an arbitrary bottom ...

Wind Effects Juan de Fuca Submarine Canyon Currents Observed
2009/4/3
Juan de Fuca submarine canyon has depths exceeding 200 m extending completely across the continental shelf. Observations of currents in the canyon during winter 1970 showed relatively large currents a...

2009/4/3
The nonlinear interaction of wave-induced air motion and the turbulent wind is examined in spectral space with the aid of a model developed through two averaging processes. The averaging periods are d...
The response of a simple Great Lake model to wind stress is studied theoretically. The model is of constant depth and of circular shape, continuously stratified with a thermocline region of linear den...
Water motion in the barotropic mode, directly forced by suddenly imposed wind stress, is investigated in basins with arbitrary topography, but paying special attention to long basins, in which the dep...
