On the Correction of Temperature and Velocity Time Series for Mooring Motion
Publisher: American Meteorological Society
Abstract: Several schemes for correcting temperature and velocity measurements from moored current meters are tested on two moorings, one of which experienced large vertical excursions as the Gulf Stream meandered over it. The ...
Observations of Gulf Stream Meander-Induced Disturbances
Publisher: American Meteorological Society
Abstract: Using moored array data collected across the Gulf Stream at 55°W, the author has investigated the dynamic signatures of the velocity fluctuations at the thermocline (550 m) and near-bottom (4000 m) levels. The cross-stream ...
Mooring Motion Corrections Revisited
Publisher: American Meteorological Society
Abstract: Several schemes are offered for the correction of temperature and velocity in the thermocline for mooring motion. They require measurements from at least two instruments spanning the thermocline and assume that the temporal ...
Observations of Internal Kelvin Waves Trapped Round Bermuda
Publisher: American Meteorological Society
Abstract: Observations of the vertical and horizontal structure of motions near Bermuda have been made with two long-term moored arrays, one relatively far from and the other close to the island. Although not coincident in time, ...
Stochastic Wave Radiation by the Gulf Stream
Publisher: American Meteorological Society
Abstract: A linear, small amplitude model of Rossby waves forced by idealized meanders is presented in order to ascertain whether or not the observed low frequency motions near the Gulf Stream are capable of being so generated. Two ...
Multilayer Hydraulic Control with Application to the Alboran Sea Circulation
Publisher: American Meteorological Society
Abstract: The flow of a single layer of fluid along a channel of variable dimensions is hydraulically controlled when long gravity waves can no longer propagate upstream at the cross-section of minimum area. For a multilayer fluid, ...
Finite Amplitude Effects on Deep Planetary Circulation over Topography
Publisher: American Meteorological Society
Abstract: Steady flow over large-scale bathymetric changes of a uniform zonal current in a two-layer fluid is studied under the assumptions that it is geostrophic, that relative vorticity can be ignored, that variations in the ...
Hydraulie Control and Flow Separation in a Multi-Layered Fluid with Applications to the Vema Channel
Publisher: American Meteorological Society
Abstract: Observations from a recent field experiment in the Vema Channel are briefly described. These show a remarkable change in the configuration of isopycnal surfaces within the channel and the development of thick, nearly ...
Structure of the Circulation Induced by a Shoaling Topographic Wave
Publisher: American Meteorological Society
Abstract: The structure of the potential vorticity flux and a mean flow induced by a topographic wave incident over a bottom slope are investigated analytically and numerically, with focus on the case that bottom friction is the ...
Structure of the Gulf Stream and Its Recirculations at 55°W
Publisher: American Meteorological Society
Abstract: Two years of direct current and temperature observations from an army of 13 current meter moorings deployed near 55°W as part of the SYNOP (Synoptic Ocean Prediction) Experiment have been used to explore the spatial and ...
