Two-Dimensional Free Oscillations in Natural Basins
Two-Dimensional Free Oscillations Natural Basins
2009/4/3
A method is designed to calculate normal modes of natural basins. The purpose is to determine the period and configuration of free oscillations in a way that provides for the full two-dimensionality o...
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...
An Analysis of Inertial Oscillations Observed Wear Oregon Coast
Inertial Oscillations Wear Oregon Coast
2009/3/7
Nearly two months of current meter data taken during the summer of 1973 at eleven depths at a station off the coast of Oregon in 100 m of water have been analyzed. The spectra show an 8% increase in t...
Irregular Grid Finite-Difference Techniques：Simulations of Oscillations in Shallow Circular Basins
Irregular Grid Finite-Difference Techniques Oscillations Shallow Circular Basins
2009/3/7
Finite-difference techniques for irregular computational grids are presented. Successful simulations of transient normal mode oscillations in shallow circular basins, where analytic solutions are know...
Inertial oscillations in current records in the top 100 m of the ocean collected on three moorings 50 and 70 km apart are examined. At 12 and 32 m depth the records are horizontally coherent at inerti...
Inertial Oscillations on the Continental Shelf of the Gulf of Lions—Observations and Theory
Inertial Oscillations Lions—Observations Continental Shelf
2009/2/9
Observations in the Gulf of Lions (northwestern Mediterranean Sea) in summer have shown that gusts of wind lasting a few days generate transient upwellings and inertial motions. Oscillations at the in...
Generation of Coastal Inertial Oscillations by Time-Varying Wind
Coastal Inertial Oscillations Time-Varying Wind
2009/1/21
The excitation of coastal inertial oscillations by a rapidly varying wind is investigated. It is shown that the mean-square response to a completely random forcing is ¯2 δ2dt, where δ is the re...
Oscillations of Dynamic Topography in the Eastern Equatorial Pacific
sea surface temperature Dynamic Topography Eastern Equatorial Pacific
2009/1/16
For 14 months in 1980–81, surface dynamic height was monitored with inverted echo sounders at five sites from 0 to 9°N along 110°W. These records show that the SEC/NECC equatorial current system was w...
A solution for a concentrated line front translating at speed U is given. It is shown that the frequency is near-inertial if Uc1, where c1 is the long internal wave speed of the first baroclinic mode....
Nondivergent Planetary Oscillations in Midlatitude Ocean Basins with Continental Shelves
Planetary Oscillations Midlatitude Ocean Basins Continental Shelves
2009/1/13
Free oscillations in square, midlatitude basins with continental shelves and planetary vorticity gradients are numerically computed using the nondivergent shallow-water equations. The topography may r...
A Two-Dimensional Model of Inertial Oscillations Generated by a Propagating Wind Field
Two-Dimensional Model Inertial Oscillation Propagating Wind Field
2009/1/12
A linear, two-dimensional, continuously stratified, viscous model has been developed to study the inertial oscillations generated by a propagating wind field. The model, an extension of that of Kundu ...

Near-Inertial Oscillations Drake Passage Internal
2009/1/10
The kinetic energy levels Of horizontal oscillations near and above the inertial frequency are described based on 84 current records made during 5 years at Drake Passage. Instrument depths ranged from...
Intraseasonal Oscillations in Sea Level along the West Coast of the Americas
Intraseasonal Oscillations Americas Sea Level
2009/1/7
Hourly observations of coastal sea level at stations from Peru to British Columbia are analyzed for low-frequency content. A space-time contour plot of sea level, from four years of data during the 19...
Observations of 20-Day Period Meridional Current Oscillations in the Upper Ocean along the Pacific Equator
Meridional Current Upper Ocean Pacific Equator
2009/1/6
Prominent oscillations of the meridional current, with a mean period of approximately 20 days, have been observed in the upper ocean over several years from May 1979 to October 1985 using moored curre...
The authors describe a self-sustaining baroclinic inertial oscillation whose energy source rests in a uniform horizontal temperature gradient. This energy is released through the agency of a stratific...
