A Possible Mechanism for Boundary Layer Mixing and Layer Formation in a Stratified Fluid
Possible Mechanism Layer Formation Boundary Layer Mixing Stratified Fluid
2009/3/9
A plate tilted at 42° from the horizontal is oscillated along its length with frequency ω and amplitude a in a linearly stratified fluid (salt water) of kinematic viscosity ν. If the Reynolds number R...
The Langmuir Circulation Instability as a Mixing Mechanism in the Upper Ocean
Langmuir Circulation Instability Mixing Mechanism Upper Ocean
2009/2/16
A numerical study of the fully nonlinear instability of the ocean to Langmuir circulations is reported. The extended Craik-Leibovich theory is used to compute the development of a mixed layer in an oc...
On the Formation of Whitecaps by a Threshold Mechanism. Part III：Field Experiment and Comparison with Theory
Whitecaps Threshold Mechanism Field Experiment
2009/2/6
This paper is the third in a series of papers which seek to evaluate the hypothesis that deep water whitecapping is predictable in terms of a threshold mechanism involving the vertical acceleration. P...

Whitecaps Monte Carlo Experiments Threshold Mechanism
2009/2/6
This paper is the second of three which seek to evaluate the hypothesis that deep water whitecapping is predictable in terms of a threshold mechanism involving the vertical acceleration.
The geomet...
On the Formation of Whitecaps by a Threshold Mechanism. Part I：Basic Formalism
Threshold Mechanism Basic Formalism
2009/2/6
In this paper and the two which follow we seek to evaluate the hypothesis that deep water whitecapping is predictable in terms of a threshold mechanism involving the vertical acceleration; i.e., that ...
Geostrophic Adjustment：A Mechanism for Frontogenesis
Frontogenesis two-dimensional model motionless fluid
2009/1/20
A simple two-dimensional model is used to determine the geostrophically adjusted state of an initially motionless fluid with lateral density gradient. It is an extension of the much studied two-layer ...
A Mechanism for the Increase of Wind Stress (Drag) Coefficient with Wind Speed over Water Surfaces：A Parametric Model
Wind Stress (Drag) Coefficient Wind Speed Water Surfaces Parametric Model
2009/1/10
A mechanism is proposed for a physical explanation of the increase in wind stress (drag) coefficient with wind speed over water surfaces. The formula explicitly incorporates the contribution of both w...
A Mechanism for the Formation of the Weddell Polynya in 1974
Weddell Polynya high-salinity mixed layer
2009/1/9
The formation of the Weddell Polynya is investigated with a one-dimensional, convective mixed-layer model, using in situ data from late summer 1974 as initial conditions. We propose that a high-salini...
An Ice Breeze Mechanism for an Ice Divergence-Convergence Criterion in the Marginal Ice Zone
marginal ice zone Ice Breeze Mechanism Ice Divergence-Convergence Criterion
2009/1/8
A coupled air-ice-ocean theoretical model for the marginal ice zone (MIZ) is developed and used to show that an off-ice and divergent wind field not only produces a dilation of the MIZ (as is generall...
Geographic and Temporal EddY Variability in the Western North Atlantic as Sensed by Satellite：An Eddy Generation Mechanism
Western North Atlantic Eddy Generation Mechanism Satellite
2009/1/8
This paper has two objectives: to establish the satellite-derived mesoscale sea surface temperature anomaly as a useful oceanographic measure and to use this measure to explore an eddy generation mech...
A Numerical Study of a Shallow Sea Front Generated by Buoyancy Flux：Generation Mechanism
Shallow Sea Front Buoyancy Flux Generation Mechanism
2008/12/27
We studied numerically the frontogenesis of shallow sea fronts such as are observed in the Kii Channel, Japan, during winter, under conditions of sea surface cooling and buoyancy influx from coast and...
The authors present a simple model for the dynamics that couple the atmospheric boundary layer and wind-generated waves. The model is empirically motivated by parameterizations for the sea state-depen...
A Mechanism for the Recurrence of Wintertime Midlatitude SST Anomalies
ocean temperature deep mixed layer Wintertime Midlatitude
2008/12/11
In the early 1970s, Namias and Born speculated that ocean temperature anomalies created over the deep mixed layer in winter could be preserved in the summer thermocline and reappear at the surface in ...
Existence and Formation Mechanism of the North Hawaiian Ridge Current
North Hawaiian Ridge Current ocean circulation
2008/11/13
Available surface drifter data are analyzed to determine the characteristics of the North Hawaiian Ridge Current (NHRC) and its relation to the ocean circulation around the Hawaiian waters. The NHRC i...
A Regional Model of Shelf Circulation near Bass Strait: A New Upwelling Mechanism
A Regional Model Bass Strait Shelf Circulation Upwelling Mechanism
2008/10/27
A study is made of the low-frequency, three-dimensional circulation and upwelling for the western region of Bass Strait, using oceanographic data and the Princeton Ocean Model. A novel radiation condi...
