Eddy growth and mixing in mesoscale oceanographic flows
Eddy growth and mixing mesoscale oceanographic flows
2009/11/13
We study the relation between changes in the Eulerian topology of a two dimensional flow and the mixing of fluid particles between qualitatively different regions of the flow. In general time dependen...
Mesoscale Variability of Sea Surface Temperatures
Mesoscale Variability Sea Surface Temperatures
2009/3/24
Results of an investigation of the nature of the mesoscale variability of sea surface temperature (SST) in the upwelling zone off the central coast of Oregon are presented. A knowledge of SST mesoscal...

Mesoscale Eddies Oceanic General Circulation Parameter Study
2009/3/24
In this investigation the wind-driven ocean circulation theories are extended to include mesoscale eddies as an integral part of the general circulation of the ocean. A two-layer numerical model of oc...

Mesoscale Eddies Oceanic General Circulation Preliminary Numerical Experiment
2009/3/24
Numerical experiments on the wind-driven ocean circulation in a closed basin show that mesoscale eddies can appear spontaneously during the integration of the equations of motion for a baroclinic ocea...
The Amplitude of Baroclinic Wave Triads and Mesoscale Motion in the Ocean
Baroclinic Wave Triads Mesoscale Motion
2009/3/24
The finite-amplitude dynamics of a resonant triad of baroclinic waves in a slightly unstable baroclinic current is examined. The wave in the triad which is linearly unstable on the current is assumed ...

Mesoscale Eddy Dynamics Eastern Tropical Pacific Ocean
2009/3/7
Active mesoscale (300 km diameter) eddy formation off the Pacific coast of Central America was observed during February 1976 by a thermal infrared sensor aboard the NOAA 4 satellite. These anticycloni...
The Role of Mesoscale Eddies in the General Circulation of the Ocean—Numerical Experiments Using a Wind-Driven Quasi-Geostrophic Model
Mesoscale Eddies Ocean—Numerical Experiments General Circulation
2009/2/23
Results from a two-layer, quasi-geostrophic, general circulation model of the ocean with fine horizontal resolution are presented. As in Holland and Lin (1975a.b), mesoscale eddies spontaneously arise...
Observation of a Baroclinic Eddy：An Example of Mesoscale Variability in the Bering Sea
Baroclinic Eddy Bering Sea Mesoscale Variability
2009/2/18
Drift buoys with shallow (17 m) drogues, released during May 1977 and tracked by satellite, delineated an eddy in the southeastern Bering Sea. Located above complex topography having a depth range of ...
Observations of mesoscale ocean eddies from the 1973 Mid-Ocean Dynamics Experiment (MODE) are used to calculate, by objective analysis, the modal coefficients, which are functions of horizontal positi...
Horizontal Deflection of Acoustic Paths by Mesoscale Eddies
Horizontal Deflection Acoustic Paths Mesoscale Eddies
2009/2/16
The horizontal angular deflection of a ray path through a circular eddy is roughly 2v, where v is the fractional variation in sound speed at the eddy center; v may reach 0.03 for intense Gulf Stream r...

Mid-Ocean Mesoscale Eddies Simulated Dynamic Balances
2009/2/13
Eulerian potential vorticity and heat balances calculated for a multi-layered quasi-geostrophic model are shown to be consistent with those inferred from the MODE data. Above the thermocline the balan...
