A simple nonlinear model of the generation of Kelvin waves is presented and applied to internal Kelvin waves in Lake Michigan. It is shown that a Kelvin wave which has a wavelength longer than the Ros...
The three-dimensional circulation produced in a homogeneous ocean by a steady wind stress is investigated when the bottom topography contains a discontinuity in gradient, such as occurs at the edge ...
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 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...

Equilibrium Range Wind-Generated Gravity Waves
2009/3/24
Phillips' hypothesis concerning the equilibrium range in the spectrum of wind-generated surface waves in deep water can be expressed either in the frequency form S(ω)ω−5 or the wavenumber form (...
Theory of Steady Wind-Driven Currents in Shallow Water with Variable Eddy Viscosity
Steady Wind-Driven Currents Shallow Water Variable Eddy Viscosity
2009/3/24
A theory is given for steady wind-driven currents in shallow water (friction depth comparable to total depth) in which the vertical eddy viscosity varies linearly with depth, from zero at the bottom t...

Continental Shelf Currents Tropical Storm Delia
2009/3/7
Storm currents are a significant part of the design hydrodynamic flow field in areas subject to tropical storms. In September 1973, Tropical Storm Delia passed over the instrumented Buccaneer platform...

Nonlinear Theory Gravity Waves Ocean's Surface Interpretation
2009/3/7
In a previous paper (Weber and Barrick, 1977), a generalization of Stokes’ perturbational technique permitted us to obtain solutions to higher orders for gravity-wave parameters for an arbitrary, two-...

Sea Straits II—Two-Layer System Wide Estuaries
2009/2/23
A frictionless nonlinear model with allowance for motions which are far from a state of geostrophic balance is considered in order to describe the dynamics of outflows consisting of two layers of flui...
