RISA Simple Kinematic Mechanism for Mixing Fluid Parcels across a Meandering Jet
Publisher: American Meteorological Society
Abstract: Recent observations of fluid parcel pathways in the Gulf Stream using isopycnal RAFOS floats revealed a striking pattern of cross-stream and vertical motion associated with meanders (Bower and Rossby 1989). In an attempt ...
Potential Vorticity Balances and Horizontal Divergence along Particle Trajectories in Gulf Stream Meanders East of Cape Hatteras
Publisher: American Meteorological Society
Abstract: Trajectories of 37 isopycnal RAFOS floats launched in the Gulf Stream off Cape Hatteras have been analyzed to examine the dynamics of meanders from a Lagrangian viewpoint. Using the float data in conjunction with information ...
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 ...
Lagrangian Observations of Meddy Formation during A Mediterranean Undercurrent Seeding Experiment
Publisher: American Meteorological Society
Abstract: Mediterranean eddies (meddies) play an important role in maintaining the temperature and salinity distributions in the North Atlantic, but relatively little is known about their early life histories, including where, how ...
Lagrangian Observations of the Deep Western Boundary Current in the North Atlantic Ocean.
Publisher: American Meteorological Society
Abstract: Twenty-six RAFOS floats were deployed in the deep western boundary current (DWBC) of the North Atlantic Ocean between the Grand Banks and Cape Hatteras in 1994?95 and tracked acoustically for up to two years. Half of the ...
Lagrangian Observations of the Deep Western Boundary Current in the North Atlantic Ocean.
Publisher: American Meteorological Society
Abstract: In this study, the authors analyze the trajectories of 18 RAFOS floats, launched in the deep western boundary current (DWBC) between the Grand Banks and Cape Hatteras to investigate the kinematics and dynamics in the region ...
Evidence for Barotropic Wave Radiation from the Gulf Stream
Publisher: American Meteorological Society
Abstract: Highly energetic velocity fluctuations associated with topographic Rossby waves are frequently observed over the continental slope and rise off the United States and Canadian east coast. It has been suggested that the ...
Interannual Variability in the Pathways of the North Atlantic Current over the Mid-Atlantic Ridge and the Impact of Topography
Publisher: American Meteorological Society
Abstract: Recent studies have indicated that the North Atlantic Ocean subpolar gyre circulation undergoes significant interannual-to-decadal changes in response to variability in atmospheric forcing. There are also observations, ...
The Influence of Propagating Waves on Cross-Stream Excursions
Publisher: American Meteorological Society
Abstract: A kinematic model is developed to examine the relationship between meander propagation and Lagrangian pressure change within a meandering jet. Basically, the model equates changes in pressure along the path of a water ...
Eddy Seeding in the Labrador Sea: A Submerged Autonomous Launch Platform Application
Publisher: American Meteorological Society
Abstract: wo submerged autonomous launch platforms (SALPs) were deployed at 500-m depth on a deep-water mooring in the northeastern Labrador Sea from 2007 to 2009 to automatically release profiling floats into passing warm-core ...
