Thermohaline Structure and Baroclinic Flow Across the Gulf of California Entrance and in the Revilla Gigedo Islands Region
Thermohaline Structure Gulf of California Entrance Baroclinic Flow Revilla Gigedo Islands Region
2009/4/3
The thermohaline structure, vertical stability and baroclinic flow between the Gulf of California entrance and the Revilla Gigedo islands are investigated by means of closely spaced salinity and tempe...
Wind–Induced Baroclinic Motions at the Edge of the Continental Shelf
Wind–Induced Baroclinic Motions Continental Shelf
2009/4/2
In a two-layer model of stratified fluid flow, motions in the internal mode are governed by the distribution of an equivalent depth he. For a typical continental shelf, the distribution of he with dis...
An experimental study is made of a baroclinic vortex produced in a two-layer fluid. After the equivalence between the experiment and the heated annulus experiment of Hide is established, it is argued ...
Time and Length Scales of Baroclinic Eddies in the Central North Pacific Ocean
Length Scales Baroclinic Eddies Central North Pacific Ocean
2009/3/26
The time and length scales of baroclinic eddies in the eastern half of the North Pacific Subtropical Gyre are examined using four data sets: 1) single vertical sections of temperature, based on closel...
Coastal current observations taken at five locations in Lake Ontario during IFYGL, in periods of summer stratification, are presented and interpreted in terms of a linear dynamical model. Wind-stress ...
Baroclinic instability is examined in a two-layer, quasi-geostrophic model for linearized mesoscale waves (i.e., with periods of a few months and length scales near the internal deformation radius). T...
Baroclinic Instability over a Slope. Part II：Finite-Amplitude Theory
Baroclinic Instability Finite-Amplitude Theory
2009/3/24
Baroclinic instability of a circular current is modified by the presence of a unidirectional bottom slope. An analytical theory is developed for the slightly unstable flow regime over a weak slope. Th...
Baroclinic Instability over a Slope. Part I：Linear Theory
Baroclinic Instability Slope Linear Theory
2009/3/24
We consider the instability properties of a circular current in the upper layer of a two-layer quasi-geostrophic ocean over a unidirectional slope. This particular flow-topography geometry is intended...
The Amplitude of Baroclinic Wave Triads and Mesoscale Motion in the Ocean
Baroclinic Wave Triads Mesoscale Motion
2009/3/24
The finite-amplitude dynamics of a resonant triad of baroclinic waves in a slightly unstable baroclinic current is examined. The wave in the triad which is linearly unstable on the current is assumed ...
On Secondary Baroclinic Instability and the Meridional Scale of Motion in the Ocean
Secondary Baroclinic Instability Meridional Scale
2009/3/24
The stability of the marginally stable baroclinic wave in a uniform zonal shear flow is studied. Although the single, marginally stable wave on a horizontally uniform baroclinic current has little or ...
Coastal-trapped waves are studied in a two-layered, non-flat shelf model. Internal Kelvin wave and quasi-geostrophic waves appear as eigenmodes of the system. The latter reduce to the familiar barotro...
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 ...
Baroclinic Boundary Currents and Long Edge-Waves in Basins with Sloping Shores
Baroclinic Boundary Currents Sloping Shores Long Edge-Waves
2009/3/9
Earlier work on baroclinic “coastal jets” and Kelvin waves in constant-depth basins is extended to basins with sloping shores. Baroclinic coastal jets are again found to be set up by an inflow or outf...
Baroclinic Instability in the Denmark Strait Overflow
Baroclinic Instability Denmark Strait Overflow
2009/3/7
Current meter records and hydrographic data taken in the Denmark Strait overflow during a one-month experiment in August-September 1973 are analyzed. Mean conditions indicate that a strong, cold overf...
Finite-Amplitude Baroclinic Disturbances in Downstream Varying Currents
Finite-Amplitude Baroclinic Disturbances Downstream Varying Currents
2009/3/7
The finite-amplitude dynamics of baroclinic disturbances in currents whose cross-stream structure varies in the downstream direction is investigated.
It is first shown under what circumstances downst...
