Continental Shelf Waves：Low-Frequency Variations in Sea Level and Currents Over the Oregon Continental Shelf
Continental Shelf Waves Sea Level Low-Frequency Variations Oregon Continental Shelf
2009/4/2
Sea level variations and currents on the Oregon continental shelf exhibit wavelike characteristics in a frequency band from approximately 0.15 to 0.45 cycle per day (cpd). Shelf wave dispersion curves...
Currents [O(0.1 m sec−1)] and sea-level variations [O(0.1 m)] on the continental shelf can be produced when atmospheric disturbances pass by. Since the atmospheric systems have length scales lar...
Continental Shelf Waves and Alongshore Variations in Bottom Topography and Coastline
Continental Shelf Waves Bottom Topography Alongshore Variations Coastline
2009/3/7
The effects of alongshore variations in bottom topography and coastline on the wind-stress-forced barotropic motion over a continental shelf and slope are studied. Perturbation methods are used to obt...
Current measurements from three stations along the east coast of Florida at about 300 m water depth with a maximum longshore separation of 180 km were used to analyze for the presence of propagating w...
Previous studies of forced, long continental shelf waves on an f-plane have considered motion on the shelf and slope which is driven by an alongshore component of the wind stress, essentially through ...
The Effects of a Variable Coriolis Parameter, Coastline Curvature and Variable Bottom Topography on Continental Shelf Waves
Variable Coriolis Parameter Coastline Curvature Variable Bottom Topography Continental Shelf Waves
2009/3/7
The effects of a variable Coriolis parameter, coastline curvature and variable bottom topography on continental shelf waves are examined for the case when the variations occur on a length scale much g...
Free, Stable Continental Shelf Waves in a Sheared, Barotropic Boundary Current
Stable Continental Shelf Waves Free Barotropic Boundary Current
2009/3/7
The dispersion characteristics of stable, discrete, barotropic, continental shelf wave (CSW) modes propagating in a barotropic boundary current are strongly modified by the dynamical effects of nonuni...
Equatorial Shelf Waves on an Exponential Shelf Profile
Equatorial Shelf Waves Exponential Shelf Profile
2009/2/23
The theory of barotropic nondivergent waves trapped on an exponential shelf lying on an equatorial β-plane is presented. The bottom contours are parallel to the equator so that phase propagation is ei...
Resonant Interactions between Shelf Waves, with Applications to the Oregon Shelf
Resonant Interactions Shelf Waves Oregon Shelf
2009/2/19
From the inviscid, unforced, barotropic long-wave equations for a rotating system, it is shown that resonant interactions between three continental shelf waves can occur. Evolution equations governing...
Diffraction of Continental Shelf Waves by Irregular Alongshore Geometry
Continental Shelf Waves Irregular Alongshore Geometry
2009/2/18
Diffraction of continental shelf waves by irregular alongshore geometry, such as ridges, canyons and bumps, is examined. The full barotropic, shelf-wave equation is treated, and the solutions include ...
Propagation of Barotropic Continental Shelf Waves over Irregular Bottom Topography
Barotropic Continental Shelf Waves Irregular Bottom Topography
2009/2/16
Using a geometry which roughly approximates that of a typical continental shelf and slope, the effects of a random bottom topography on free barotropic shelf waves are found. The bathymetric irregular...

Continental Shelf Waves Alongshore Variations Bottom Topography
2009/2/13
The effects of alongshore variations in bottom topography on wind-stress-forced barotropic motion over a continental shelf and slope are studied. An idealized channel model with a weakly sloping botto...
The Scattering of Continental Shelf Waves by an Isolated Topographic Irregularity
Continental Shelf Waves Isolated Topographic Irregularity
2009/2/13
A model for the scattering of a continental shelf wave by a small, isolated and smooth topographic irregularity is developed. It is found that a wave of frequency ω, incident on a bump of a sufficient...

2009/2/8
The low-frequency current fluctuations on the Oregon shelf changed dramatically from winter to spring, 1975. A much faster offshore energy decay occurred simultaneously with a sharp decrease in the al...

Diurnal Period Shelf Waves Tidal Currents
2009/2/7
Continental shelf waves of diurnal period are shown to be generated by tidally induced Reynolds stresses within a bottom Stokes-scale boundary layer. The theory is applicable to a uniformly rotating, ...
