RISComments on “The Significance of Half-inertial Flow in the Eastern Equatorial Pacific”
Publisher: American Meteorological Society
Abstract: It is shown that the instability waves regularly observed in the tropical Pacific and Atlantic oceans do not necessarily contain oscillations of half the local inertial frequency. Rather, it is hypothesized that the flow ...
Temporal Sampling Requirements for Surface Drifting Buoys in the Tropical Pacific
Publisher: American Meteorological Society
Abstract: Drifting buoy data from the eastern tropical Pacific Ocean are used to evaluate the degradation of sea surface temperature and current information incurred by reducing the number of transmissions from drifting buoys using ...
Direct Measurements of Current Shear in the Tropical Pacific Ocean and Its Effect on Drift Buoy Performance
Publisher: American Meteorological Society
Abstract: Measurements of ocean surface currents derived from drift buoy trajectories are subject to errors caused by slippage of the buoy relative to the surrounding water. This slippage error is caused by a number of forces acting ...
Evaluation of Sea Surface Temperature Measurements from Drifting Buoys
Publisher: American Meteorological Society
Abstract: Three drift-buoy designs have been deployed since 1988 in substantial numbers in the tropical Pacific Ocean by United States participants as part of the Tropical Ocean Global Atmosphere (TOGA) Pan Pacific Surface Current ...
Quality Control and Interpolations of WOCE-TOGA Drifter Data
Publisher: American Meteorological Society
Abstract: Satellite-tracked drifting buoy data are being collected by numerous investigators and agencies in several countries for the World Ocean Circulation Experiment-Tropical Oceans Global Atmosphere (WOCE-TOGA) Surface Velocity ...
Tropical Pacific Ocean Mixed Layer Heat Budget: The Pacific Cold Tongue
Publisher: American Meteorological Society
Abstract: Data from satellite-tracked drifting buoys and VOS/XBT profiles for the years 1979?95 were used to evaluate the seasonal cycle of how major oceanic processes redistribute heat in the cold tongue region of the tropical ...
Observation of a Baroclinic Eddy: An Example of Mesoscale Variability in the Bering Sea
Publisher: American Meteorological Society
Abstract: Drift buoys with shallow (17 m) drogues, released during May 1977 and tracked by satellite, delineated an eddy in the southeastern Bering Sea. Located above complex topography having a depth range of 200 to 3000 m, the ...
Steady-State Diagnostic Model of the New York Bight
Publisher: American Meteorological Society
Abstract: A qualitative evaluation is made of the output from a finite-element, steady-state diagnostic model to observed time-averaged currents. The model uses a vorticity balance equation with linear bottom friction and inputs ...
Coastal Flow in the Northern Gulf of Alaska as Observed by Dynamic Topography and Satellite-Tracked Drogued Drift Buoys
Publisher: American Meteorological Society
Abstract: Drifting buoys and dynamic topography over the continental shelf in the northern Gulf of Alaska are used to describe the coastal circulation and flow in the offshelf Alaska Current. One permanent anti-cyclonic eddy is ...
