A Comparison of Length Scales and Decay Times of Turbulence in Stably Stratified Flows
Publisher: American Meteorological Society
Abstract: An examination of average values of a buoyancy length scale, LR = (?/N3)½, and a Thorpe scale, LT, computed from vertical profiles of oceanic turbulence at 150°W in the tropical Pacific Ocean, shows reasonable agreement ...
Pacific Equatorial Turbulence
Publisher: American Meteorological Society
Abstract: In January and February 1979 a free-fall vehicle was deployed at 150°W near the equator to sample velocity and temperature microstructure. Airfoil shear probes on the vehicle are able to resolve the peak of the velocity ...
Energy Flux and Generation of Diurnal Shelf Waves along Vancouver Island
Publisher: American Meteorological Society
Abstract: Recent observations along the west coast of Vancouver Island reveal among diurnal-period currents due to a tidally driven continental shelf wave superimposed upon a Kelvin wave. The energy flux of this system is investigated ...
Bottom Stress Estimates from Vertical Dissipation Rate Profiles on the Continental Shelf
Publisher: American Meteorological Society
Abstract: Measurements of the near-bottom distribution of the turbulent dissipation rate on the continental shelf west of Vancouver Island are used to calculate bottom stress. A free-failing vertical profiler with microstructure ...
The Generation of Diurnal Period Shelf Waves by Tidal Currents
Publisher: American Meteorological Society
Abstract: 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, homogeneous ocean of ...
Diurnal-Period Continental Shelf Waves along Vancouver Island: A Comparison of Observations with Theoretical Models
Publisher: American Meteorological Society
Abstract: Current and sea level data from the Coastal Oceanic Dynamics Experiment conducted of Vancouver Island from May 1979 to September 1980 reveal shelf waves of diurnal period whose motions dominate the flow over the continental ...
Confidence Limits for Friction Velocity Determined from Turbulence Profiles in Coastal Waters
Publisher: American Meteorological Society
Abstract: It is possible to determine the friction velocity u* at the ocean bottom in coastal waters by measuring a profile of the local rate of turbulent dissipation. A single profile of dissipation gives one computation of u*. The ...
Turbulent Dissipation Over the Continental Slope Off Vancouver Island
Publisher: American Meteorological Society
Abstract: Thirteen profiles of the rate of viscous dissipation of turbulent kinetic energy &epsi? were made over the continental slope off Vancouver Island between 12 and 14 May 1980 in conjunction with CTD and moored current-meter ...
Anticyclonic Eddies in the Alaskan Stream
Publisher: American Meteorological Society
Abstract: Anticyclonic eddies propagating southwestward in the Alaskan Stream (AS) were investigated through analysis of altimetry data from satellite observations during 1992?2006 and hydrographic data from profiling float observations ...
