High-Frequency Components of Ocean Waves and Their Relation to the Aerodynamic Roughness
High-Frequency Components Aerodynamic Roughness Ocean Waves
2009/4/2
Ocean waves of high frequency (from about 10 to 200 rad sec−1) were observed by means of a thin capacitance-type wave gage. The representative rms height, hp, of the sea-surface irregularities a...
Continental Shelf Waves：Low-Frequency Variations in Sea Level and Currents Over the Oregon Continental Shelf
Continental Shelf Waves Sea Level Low-Frequency Variations Oregon Continental Shelf
2009/4/2
Sea level variations and currents on the Oregon continental shelf exhibit wavelike characteristics in a frequency band from approximately 0.15 to 0.45 cycle per day (cpd). Shelf wave dispersion curves...

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 ...
