An integral model of the steady-state dynamics of a shallow, small-scale oceanic front is developed. Such fronts have been observed at the boundaries of river plumes discharging into coastal sea water...
On North Pacific Temperature, Salinity, Sound Velocity and Density Fronts and their Relation to the Wind and Energy Flux Fields
North Pacific Temperature Sound Velocity Salinity Density Fronts Energy Flux Fields
2009/3/24
The main oceanic fronts of the North Pacific are investigated and the principal frontogenetic processes described. Fronts are features of the upper ocean and occur near mass transport and energy flux ...
Formation of Meanders, Fronts, and Cutoff Thermal Pools in a Baroclinic Ocean Current
Baroclinic Ocean Current Cutoff Thermal Pools
2009/3/24
Using an analytical model similar to that previously applied by the authors to the atmosphere, calculations are made showing how second-order, nongeostrophic effects can modify a two-layer baroclinic ...
Oceanic Subarctic Fronts of the Central Pacific：Structure of and Response to Atmospheric Forcing
Central Pacific Oceanic Subarctic Fronts Atmospheric Forcing
2009/3/7
The oceanic fronts in the subarctic region of the central North Pacific are investigated and related to atmospheric forcing. The thermohaline structure indicates a near balance between horizontal temp...
The dynamics of downwelling fronts observed along the steep and elongated southern shore of Lake Ontario are investigated by considering the nonlinear response to surface forcing of one-layer and two-...
The Circulation Dynamics and Thermodynamics of Upper Ocean Density Fronts
Circulation Dynamics Thermodynamics Upper Ocean Density Fronts
2009/2/19
This paper extends a previous hydrodynamic circulation model of established, persistent upper ocean density fronts by including a thermodynamic or buoyancy equation in the integral treatment. An analy...
The establishment and maintenance of the mean hydrographic properties of large-scale density fronts in the upper ocean is considered. The dynamics is studied by posing an initial value problem starrin...
In this paper a mechanism is proposed which could be responsible for the formation of sharp horizontal density gradients such as those observed in shallow seas, from fluid which initially has weak hor...
The Dynamics of Oceanic Fronts. Part II：Shelf Water Structure Due to Freshwater Discharge
Shelf Water Structure Freshwater Discharge Oceanic Fronts
2009/2/10
In Part I of this series, a framework was introduced for the study of oceanic frontal dynamics. The dynamics was studied by posing an initial value problem, starting with a near-surface discharge of b...
A Formal Theory of Internal Wave Scattering with Applications to Ocean Fronts
Internal Wave Scattering Ocean Fronts
2009/2/10
A concise theory for scattering of internal waves at localized inhomogeneities (i.e., topographic features, baroclinicity in the density field, variations of the mean sea level, jetlike currents) in t...
Mixed Layers and Fronts in Simple Ocean Circulation Models
Mixed Layers Simple Ocean Circulation Models Fronts
2009/2/9
A three-dimensional regime with a differentially heated mixed layer on top of an ideal fluid interior is considered in a situation which corresponds to the interior of the well-known wind-driven model...
Measurements of Sea-State Variations Across Oceanic Fronts Using Laser Profilometry
Sea-State Variations Oceanic Fronts Laser Profilometry
2009/2/8
As part of the Grand Banks Experiment in May 1979, airborne laser profilometer measurements of the ocean wave field were made across a large cold-water extrusion situated over the Newfoundland Ridge. ...
Benthic Observations on the Madeira Abyssal Plain：Fronts
Fronts Benthic Observations Madeira Abyssal Plain
2009/2/6
Analysis of data from a mooring with five vector-averaging current meters between 10 and 70 m above the bed of the Madeira Abyssal Plain reveals the existence of narrow regions with relatively large g...
Propagating Long Waves on Oceanic Density Fronts：An Analytic Model
Propagating Long Waves Oceanic Density Fronts Analytic Model
2009/1/21
An analytic model of long, propagating free-wave perturbations to an established upper ocean density front is developed. The primary purpose of the model is to illuminate basic frontal wave mechanisms...

2009/1/12
Density fronts on the U.S. southeastern continental shelf, during winter, am formed by (i) breakdown of the shelf-break front by Gulf Stream meanders or strong southward winds or both, (ii) shoreward ...
