Propagation of Barotropic Continental Shelf Waves over Irregular Bottom Topography
Publisher: American Meteorological Society
Abstract: 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 irregularity induces damping ...
Buoyancy Arrest and Shelf–Ocean Exchange
Publisher: American Meteorological Society
Abstract: hen steady flow in a stratified ocean passes between the continental slope and open ocean, its ability to cross isobaths is potentially limited by buoyancy arrest. If the bottom Ekman transport vanishes and there are no ...
Continental Shelf Baroclinic Instability. Part I: Relaxation from Upwelling or Downwelling
Publisher: American Meteorological Society
Abstract: here exists a good deal of indirect evidence, from several locations around the world, that there is a substantial eddy field over continental shelves. These eddies appear to have typical swirl velocities of a few centimeters ...
Surface Cooling, Winds, and Eddies over the Continental Shelf
Publisher: American Meteorological Society
Abstract: odels show that surface cooling over a sloping continental shelf should give rise to baroclinic instability and thus tend toward gravitationally stable density stratification. Less is known about how alongshore winds affect ...
Topographic Drag Due to Barotropic Flow over the Continental Shelf and Slope
Publisher: American Meteorological Society
Abstract: A barotropic model is formulated to investigate the topographic drag due to steady barotropic alongshore flow over the continental shelf and slope. The topography is extensive, irregular and of small amplitude. Topographic ...
A Comparison of Long Coastal Trapped Wave Theory with Observations off Peru
Publisher: American Meteorological Society
Abstract: The agreement between coastal trapped wave theory and observation is studied for the case of observations made off Peru during the 1977 CUEA JOINT-II experiment. Wave properties are calculated using a numerical model with ...
The Effect of Bottom Friction on Low-Frequency Coastal Trapped Waves
Publisher: American Meteorological Society
Abstract: An approximate technique is presented for including the effect of turbulent bottom friction in the forced first-order wave equation governing long generalized coastal trapped waves. The resulting governing equations include ...
Observations of the Response of Thermocline Currents to a Hurricane
Publisher: American Meteorological Society
Abstract: In September 1985, the eye of Hurricane Gloria passed within about 100 km of a current meter mooring in the western North Atlantic. Data from this mooring provide a clear view of the vertical structure of the near-inertial ...
Energy Conservation in Coastal-Trapped Wave Calculations
Publisher: American Meteorological Society
Abstract: A consideration of energy conservation for coastal-trapped waves shows that, for a slowly varying medium, the normalization of the wave modes is not arbitrary. Errors related to incorrect normalization are demonstrated for ...
On the Damping of Free Coastal-Trapped Waves
Publisher: American Meteorological Society
Abstract: A perturbative method is presented for estimating the decay time of subinertial coastal-trapped waves under a wide range of conditions where damping is relatively weak. Bottom friction is sometimes much more important than ...
