A fractal model for the sea state bias in radar altimetry
fractal model sea state bias radar altimetry
2009/11/13
The Kirchhoff approximation is used to determine the sea state bias in radar altimetry. A weakly nonlinear model of the sea waves is used to derive the joint moments of two different points separated ...
Numerical Simulation Studies of Oceanic Anomalies in the North Pacific Basin. I：The Ocean Model and the Long-Term Mean State
Oceanic Anomalies North Pacific Basin Long-Term Mean State
2009/2/23
A three-dimensional, prognostic numerical model of the North Pacific Ocean, possessing an actual coastal configuration and ten layers (but constant depth), has been developed in order to show the phys...
Steady-State Diagnostic Model of the New York Bight
Steady-State Diagnostic Model New York Bight
2009/2/19
A qualitative evaluation is made of the output from a finite-element, steady-state diagnostic model to observed time-averaged currents. The model uses a vorticity balance equation with linear bottom f...

Steady-State Energy Balance Short Gravity Wave Systems
2009/2/18
Steady-state energy balances of short gravity wave systems generated in a wave tank with and without airflow have been measured and compared with the predictions of perturbation theory. Wind-wave spec...
Simulation and Verification of Lake Ontario’s Mean State
International Field Year for the Great Lakes Mean State
2009/2/10
A numerical dynamic model based on primitive equations has been developed for Lake Ontario. Many experimental tests for parameter selections and alternative formulations of physical processes in the m...
Continuously Stratified Models of the Steady-State Equatorial Ocean
Stratified Models Steady-State Equatorial Ocean
2009/2/9
Two linearized, vertically diffusive steady-state models are formulated on an equatorial β-plane. The purpose is (a) to investigate the vertical boundary-layer structure in a continuously stratified o...
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. ...
Steady-State Diagnostic Model of Summer Mean Circulation on the Georgia Shelf
Steady-State Diagnostic Model Georgia Shelf Summer Mean Circulation
2009/2/8
The Galt (1975) diagnostic model was used to investigate summer circulation on the Georgia shelf. The steady-state model uses a finite-element method to solve the depth-integrated vorticity equation f...
Effects of Variable and Anisotropic Diffusivities in a Steady-State Diffusion Model
Steady-State Diffusion Model Anisotropic Diffusivities Variable
2009/2/8
The hypothesis that variations in eddy diffusivity may account for some aspects of the observed distributions of oceanic scalars is examined by generating solutions to the diffusion equation with spat...
Double-Diffusive Interleaving. Part II：Finite Amplitude, Steady State Interleaving
Double-Diffusive Interleaving Finite Amplitude Steady State Interleaving
2009/1/16
The exponentially growing solutions of the linear stability analysis of double-diffusive interleaving are allowed to grow to finite amplitude. At this stage the double-diffusive fluxes across the intr...
