Bore formation,evolution and disintegration into solitons in shallow inhomogeneous channels
Bore formation evolution disintegration shallow inhomogeneous channels
2009/11/12
The propagation of nonlinear surface waves in channels of smoothly variable in space cross section is studied theoretically and by means of numerical computations. The mathematical model describing wa...
Negative Oceanic Heat Flux as a Cause of Water-Mass Formation
Negative Oceanic Heat Flux Water-Mass Formation
2009/4/3
Regions of large (>60 kcal cm−2 year−1) net annual heat flux from the oceans to the atmosphere are found only on the western sides of Northern Hemisphere oceans and in the Norwegian Sea, a...
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 ...
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...
Warm core closed mesoscale eddies have been repeatedly observed off the southeastern coast of Australia. One eddy was observed to close off around latitude 35°S during the period February–March 1975. ...
A Dynamical-Numerical Study of the Formation and Evolution of Large-Scale Ocean Anomalies
sea surface temperature Formation Large-Scale Ocean Anomalies
2009/2/23
To identify oceanic processes responsible for the formation and evolution of large-scale thermal anomalies, a series of initial-value model simulations are carried out using a 10-level primitive equat...
Winter Circulation in the Western Gulf of Maine：Part 1. Cooling and Water Mass Formation
Winter Circulation Western Gulf Water Mass Formation
2009/2/23
The mean circulation on the northeast continental shelf in the region of the Gulf of Mexico is discussed in terms of a simple box model, based on volume transports and mean salinities estimated from e...
Mixing and Water-Mass Formation in the Australian Subantarctic
Water-Mass Formation Australian Subantarctic
2009/2/10
A cruise south of eastern Australia confirmed the formation of a Subantarctic Mode Water type in late winter on the equatorward side of the Subantarctic Front. This water type, mixed with the winter s...
The Formation of Labrador Sea Water. Part II. Mesoscale and Smaller-Scale Processes
Labrador Sea Water Mesoscale Smaller-Scale Processes
2009/2/6
In a previous paper, Clarke and Gascard argued that the formation of Labrador Sea Water was taking place in a cyclonic gyre set up each winter in the western Labrador Sea.
Within the gyre and at it...
The Formation of Labrador Sea Water. Part I：Large-Scale Processes
Labrador Sea Water Large-Scale Processes
2009/2/6
Data obtained in the western Labrador Sea during March 1976 by Hudson are analysed to show that new Labrador Sea Water was being formed at this time. On the basis of hydrographic and moored current-me...
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...

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...

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 ...
Formation of Eddies and Transverse Currents in a Two-Layer Channel of Variable Bottom with Application to the Lower St. Lawrence Estuary
Transverse Currents Two-Layer Channel Variable Bottom Lower St. Lawrence Estuary
2009/2/5
Baroclinic shelf waves and Kelvin waves in a two-layer channel of variable bottom are discussed using a simple numerical model. Two different propagation directions are shown to be possible, analogous...
Mutual Intrusion of a Gravity Current and Density Front Formation
Mutual Intrusion Gravity Current Density Front Formation
2009/1/20
A two-dimensional prognostic model was employed to examine the mutual intrusion of a gravity current and the formation of a density front. The results indicated strong vertical motion near the front a...
