GCM Study of Tropical–Subtropical Upper-Ocean Water Exchange
Tropical–Subtropical Upper-Ocean Water Exchange
2008/12/17
Experiments with an oceanic general circulation model indicate that the tropical and subtropical oceanic circulations are linked in three ways. Far from coast in the oceanic interior, equatorial surfa...
A Closer Look at Particle Exchange in the Gulf Stream
Particle Exchange Gulf Stream eddy-resolving GCM
2008/12/16
The trajectories of 95 isopycnal floats deployed in the Gulf Stream in the last decade have shown that a substantial amount of particle exchange takes place between the Gulf Stream and the surrounding...
Influence of Space-Time Averaging on the Ocean-Atmosphere Exchange Estimates in the North Atlantic Midlatitudes
Space-Time Averaging North Atlantic Midlatitudes Ocean-Atmosphere
2008/12/16
“Classical” and “sampling” methods of air-sea exchange estimates are considered. On the basis of meteorological observations at ocean weather stations in the North Atlantic, datasets of midlatitudinal...
A Simple Model of the Mass Exchange between the Subtropical and Tropical Ocean
Mass Exchange Subtropical Tropical Ocean
2008/12/16
A simple ventilated thermocline model is used to study the subtropical-tropical mass exchange. It is found that the water subducted in the western subtropical gyre (recirculating window) tends to reci...
A Numerical Study of the Circulation of the Bering Sea Basin and Exchange with the North Pacific Ocean
Bering Sea Basin North Pacific Ocean three-layer hydrodynamic model
2008/12/15
A limited-area, primitive equation, three-layer hydrodynamic model, with realistic coastlines and bathymetry and ° resolution, is used to investigate the circulation of the Bering Sea basin and the ad...
Frictionally Modified Rotating Hydraulic Channel Exchange and Ocean Outflows
Ocean Outflows rotating hydraulic control model
2008/12/12
Laboratory experiments of two-layer exchange through channels of circular and half-circular cross section are described. Simple theoretical limits on exchange for the circular channels are obtained fr...
Time-Dependent Two-Layer Hydraulic Exchange Flows
Time-Dependent Two-Layer Hydraulic Exchange Flows
2008/12/11
A theory is presented for time-dependent two-layer hydraulic flows through straits. The theory is used to study exchange flows forced by a periodic barotropic (tidal) flow. For a given strait geometry...
Lagrangian Studies of Fluid Exchange between the Gulf Stream and Surrounding Waters
Fluid Exchange Surrounding Waters Gulf Stream
2008/12/11
Between spring of 1988 and winter of 1990, 75 RAFOS floats were released east of Cape Hatteras near the center of the Gulf stream on the 26.8 σt surface, O (15°C). The purpose of this sequential deplo...
Air–Ice–Ocean Momentum Exchange. Part 1：Energy Transfer between Waves and Ice Floes
ocean surface waves marginal ice zone ice floes
2008/12/10
The energy exchange between ocean surface waves and ice floes in the marginal ice zone (MIZ) involves the scattering and attenuation of wave energy and the excitation of oscillation modes of the ice f...
Fluid Exchange across a Meandering Jet Quasiperiodic Variability
Fluid Exchange meandering jet developed two-dimensional kinematic model
2008/12/10
In this paper, the motion of fluid parcels in the two-dimensional kinematic model of a meandering jet developed by Bower and Samelson is studied. The earlier work is extended by considering quasiperio...
The Subtropical/Subpolar Gyre Exchange in the Presence of Annually Migrating Wind and a Meandering Jet：Water Mass Exchange
mean Lagrangian transport Water Mass Exchange Annually Migrating Wind
2008/12/3
A simple barotropic double gyre–jet ocean circulation model is developed, driven by surface wind. The model consists of a subtropical gyre in the south and a subpolar gyre in the north and a meanderin...
Exchange Geometry Revealed by Float Trajectories in the Gulf Stream
Exchange Geometry Float Trajectories Gulf Stream
2008/12/3
In an effort to understand the extent to which Lagrangian pathways in the Gulf Stream indicate fluid exchange between the stream and its surroundings, trajectories of RAFOS floats are viewed in a fram...
Assessing seasonality of biochemical CO2 exchange model parameters from micrometeorological flux observations at boreal coniferous forest
seasonality biochemical CO2 exchange model parameters micrometeorological flux observations
2010/1/18
The seasonality of the NEE of the northern boreal coniferous forests was investigated by means of inversion modelling using eddy covariance data. Eddy covariance data was used to optimize the biochemi...
Circumpolar transport and air-surface exchange of atmospheric mercury at Ny-Ålesund (79° N), Svalbard, spring 2002
