Energy Transfer from High-Shear, Low-Frequency Internal Waves to High-Frequency Waves near Kaena Ridge, Hawaii
Publisher: American Meteorological Society
Abstract: vidence is presented for the transfer of energy from low-frequency inertial?diurnal internal waves to high-frequency waves in the band between 6 cpd and the buoyancy frequency. This transfer links the most energetic waves ...
Subharmonic Energy Transfer from the Semidiurnal Internal Tide to Near-Diurnal Motions over Kaena Ridge, Hawaii
Publisher: American Meteorological Society
Abstract: onlinear energy transfers from the semidiurnal internal tide to high-mode, near-diurnal motions are documented near Kaena Ridge, Hawaii, an energetic generation site for the baroclinic tide. Data were collected aboard the ...
Parametric Subharmonic Instability of the Internal Tide at 29°N
Publisher: American Meteorological Society
Abstract: bservational evidence is presented for transfer of energy from the internal tide to near-inertial motions near 29°N in the Pacific Ocean. The transfer is accomplished via parametric subharmonic instability (PSI), which ...
Scaling Turbulent Dissipation in the Transition Layer
Publisher: American Meteorological Society
Abstract: ata from three midlatitude, month-long surveys are examined for evidence of enhanced vertical mixing associated with the transition layer (TL), here defined as the strongly stratified layer that exists between the well ...
Wirewalker Dynamics
Publisher: American Meteorological Society
Abstract: wirewalker exploits the difference in vertical motion between a wire attached to a surface buoy and the water at the depth of a profiling body to provide the power to execute deep profiles: when the wire?s relative motion ...
Energy Flux and Dissipation in Luzon Strait: Two Tales of Two Ridges
Publisher: American Meteorological Society
Abstract: nternal tide generation, propagation, and dissipation are investigated in Luzon Strait, a system of two quasi-parallel ridges situated between Taiwan and the Philippines. Two profiling moorings deployed for about 20 days ...
Global Patterns of Diapycnal Mixing from Measurements of the Turbulent Dissipation Rate
Publisher: American Meteorological Society
Abstract: he authors present inferences of diapycnal diffusivity from a compilation of over 5200 microstructure profiles. As microstructure observations are sparse, these are supplemented with indirect measurements of mixing obtained ...
Climate Process Team on Internal-Wave Driven Ocean Mixing
Publisher: American Meteorological Society
Abstract: cent advances in our understanding of internal-wave driven turbulent mixing in the ocean interior are summarized. New parameterizations for global climate ocean models, and their climate impacts, are introduced.
