Altimetry-observed semi-annual cycle in the South China Sea: Real signal or alias of K1 tidal error?
sea level semi-annual cycle satellite altimetry South China Sea
2009/11/17
There have been a number of applications of satellite altimetry to seasonal and interannual sea level variability in the South China Sea. However, these applications usually exclude shallow waters alo...
The Structure of the Residual Flow in an Offshore Tidal Stream
Residual Flow an Offshore Tidal Stream
2009/4/3
A theoretical account is given of the turbulent boundary layer at the ocean floor beneath a co-oscillating tidal flow. A parameterization, involving the techniques described by Johns and Dyke, is used...
Tidal Oscillations of an Enclosed Rotating Fluid
Enclosed Rotating Fluid Tidal Oscillations
2009/4/2
Observations of surface waves in a tilted rotating circular basin of paraboloidal bottom reveal quantitatively the limitations of the predictability of tides by linear inviscid analyses. Through nonli...
Tidal and Sub-inertial Fluctuations in the Florida Current
Sub-inertial Fluctuations Florida Current
2009/3/26
A 50-day time series was obtained from a current meter mooring in the Florida Current off Miami. The results agree with earlier observations regarding the significance of several-day oscillations in t...
New co-amplitude and cotidal charts of the central Pacific Ocean have been constructed for constituents M2, S2, N2, K1 and O1. The charts exhibit some significant differences from previous attempts. A...
On the Calculation of Tidal Currents in Homogeneous Estuaries
Tidal Currents Homogeneous Estuaries
2009/3/7
This paper describes a new approach to the computation of tidal flow in homogeneous estuaries with irregular boundary configurations and of arbitrary depth. The governing equations are the standard ve...
Predicting Changes in Tidal Regime：The Open Boundary Problem
Tidal Regime The Open Boundary Problem Predicting Changes
2009/3/7
Attempts to predict the impact on a tidal regime of large engineering structures are generally based on the use of a numerical model which is calibrated to reproduce the natural tidal regime and then ...
The Modeling of Tidal Flow in a Channel Using a Turbulence Energy Closure Scheme
Turbulence Energy Closure Scheme Tidal Flow
2009/2/23
A parameterization scheme is developed that is suitable for the modeling of turbulence in marine systems and an application is made to the determination of the tidal structure in an elongated channel....
Non-Tidal Variability in the Chesapeake Bay and Potomac River：Evidence for Non-Local Forcing
Non-Tidal Variability Chesapeake Bay Potomac River Non-Local Forcing
2009/2/23
Non-tidal variability in the Chesapeake Bay and Potomac River, and its relation to atmospheric forcing, is examined from two-month sea level and bottom current measurements. The dominant sea level flu...
Some Effects of an Elliptic Ridge on Waves of Tidal Frequency
Elliptic Ridge Waves Tidal Frequency
2009/2/23
A numerical finite-difference model using the Laplace tidal equations on an f-plane was developed to predict how tidal motion is disturbed by an elliptic ridge. With the use of an open-ocean matching ...
A Study of Tidal Energy Dissipation and Bottom Stress in an Estuary
Tidal Energy Dissipation Bottom Stress Estuary
2009/2/19
A Method for inferring an area-averaged bottom stress and energy dissipation rate in a tidal estuarine channel is presented. The one-dimensional continuity and momentum relations are developed using s...
A new general theory has been developed to determine both the tidal response of estuaries and the effects of cross-channel tidal barriers on this response. The theory is shown to be widely applicable ...
Tidal Exchange through a Strait：A Numerical Experiment Using a Simple Model Basin
Tidal Exchange Simple Model Basin Strait
2009/2/19
In order to investigate the mechanism of tidal exchange through a strait, we numerically track the Lagrangian movement of water particles over a full cycle of the M2 tide. As a result, it is found tha...

Topographic Rectification Georges Bank Tidal Currents
2009/2/18
The rectification of M2 tidal currents on the sloping sides of Georges Bank is predicted to make an important year-round contribution to its observed mean clockwise circulation. A rectification mechan...
The Relationship of Tidal and Low-Frequency Currents on the North Slope of Georges Bank
Tidal Low-Frequency Currents North Slope of Georges Bank
2009/2/18
Measured currents at the steeply sloping north edge of Georges Bank show an unusually strong correlation between tidal and lower frequency components. The dominant current constituents are the rotary ...
