Equatorial Ocean Response to Rapidly Translating Wind Bursts
Publisher: American Meteorological Society
Abstract: The response of the ocean at low latitude to idealized westerly wind bursts can be described as a wave wake composed of equatorial gravity and Rossby-gravity modes. The excited waves are those with phase speeds that match ...
Deep Currents and Their Interpretation as Equatorial Waves in the Western Pacific Ocean
Publisher: American Meteorological Society
Abstract: Vertical profiles of current and density made within 5° latitude of the equator along longitudes 168 and 179°E (the vicinity of the Gilbert Islands) reveal multiple deep current reversals which are confined to the equator. ...
Variability in the Upper-Ocean Internal Wave Field at a Sargasso Sea Site
Publisher: American Meteorological Society
Abstract: Two 3.5 month time series records of upper-ocean current and density profiles collected in opposite seasons as part of the LOTUS (Long-Term Upper-Ocean Study) project at 34°N, 70°W indicate substantial variation in the ...
Equatorial Wave Vertical Modes Observed in a Western Pacific Island Array
Publisher: American Meteorological Society
Abstract: A two-year array of sea-level and deep current and temperature measurements made in the Gilbert Group, Republic of Kiribati, is used to verify the hypothesis that equatorial gravity waves in baroclinic modes are responsible ...
Implications of Ocean Bottom Reflection for Internal Wave Spectra and Mixing
Publisher: American Meteorological Society
Abstract: A linear internal wave model for reflection off a sloping bottom applied to a field of horizontally isotropic waves typical of the deep ocean leads to a strongly perturbed frequency-vertical wavenumber energy spectrum. The ...
Moored Observations of Deep Low-Frequency Motions in the Central Pacific Ocean: Vertical Structure and Interpretation as Equatorial Waves
Publisher: American Meteorological Society
Abstract: Two-year time series of current and temperature collected in the deep equatorial central Pacific 0cean as part of the Pacific Equatorial Ocean Dynamics (PEQUOD) project indicate that motions with vertical scales comparable ...
The Subinertial Momentum Balance of the North Atlantic Subtropical Convergence Zone
Publisher: American Meteorological Society
Abstract: The upper-ocean to forcing by pressure gradients and wind stress is examined using observations from the Frontal Air?Sea Interaction Experiment. A moored way acquired time series of winds. upper-ocean currents, temperatures, ...
Subthermocline Eddies over the Washington Continental Slope as Observed by Seagliders, 2003–09
Publisher: American Meteorological Society
Abstract: n the California Current System, subthermocline, lenslike anticyclonic eddies generated within the California Undercurrent (CU) are one mechanism for lateral transport of the warm, saline waters of the CU. Garfield et al. ...
Horizontal Stratification during Deep Convection in the Labrador Sea
Publisher: American Meteorological Society
Abstract: eep convection?the process by which surface waters are mixed down to 1000 m or deeper?forms the primary downwelling of the meridional overturning circulation in the Northern Hemisphere. High-resolution hydrographic ...
Buoyant Eddies Entering the Labrador Sea Observed with Gliders and Altimetry
Publisher: American Meteorological Society
Abstract: Intense, buoyant anticyclonic eddies spawned from the west Greenland boundary current were observed with high-resolution autonomous Seaglider hydrography and satellite altimetry as they entered the Labrador Sea interior. ...
