Numerical Model of Convection Driven by a Surface Stress and Non-Uniform Horizontal Heating
Convection Driven Surface Stress Non-Uniform Horizontal Heating
2009/4/3
This paper examines the two-dimensional convective motion of a nonrotating incompressible Boussinesq fluid heated non-uniformly from below. The fluid container is rectangular; the side and top boundar...
Theoretical Aspects of Wind-Driven Currents in a Sea or Lake of Variable Depth with No Horizontal Mixing
Wind-Driven Currents Variable Depth with No Horizontal Mixing
2009/4/3
Steady-state wind-driven circulations in a basin of variable depth, with only vertical turbulent mixing, are considered. The geostrophic flow away from the coast is determined for an arbitrary bottom ...
Horizontal Coherence of Temperature Microstructure
Horizontal Coherence Temperature Microstructure
2009/3/24
Temperature gradient records from vertical lowerings of an array of four thermometers are used to trace microstructure features horizontally over a distance of 46 cm. Identifiable features are found t...
A Numerical Study of Time-Dependent Turbulent Ekman Layers over Horizontal and Sloping Bottoms
Time-Dependent Turbulent Ekman Layers Sloping Bottoms Horizontal
2009/3/24
A numerical study is made of a time-dependent turbulent Ekman bottom boundary layer. Parameters for the model were chosen to simulate conditions near the bottom of the Florida Current in the Straits o...
A Determination of Horizontal Divergence in the Gulf Stream off Cape Lookout
Horizontal Divergence Gulf Stream off Cape Lookout
2009/3/9
A horizontal divergence of 2×10−5 sec−1 was determined by tracking three shallow drogues in the speed axis of the Gulf Stream. Concurrent bathythermograph soundings along a drogue track su...
Horizontal Random Temperature Structure of the Ocean
Horizontal Random Temperature Structure Ocean
2009/3/7
A theoretical model of the spatial spectrum of horizontally distributed thermal microstructure is developed for anisotropic turbulence. A two-term power law representation is obtained for the horizont...
Horizontal Diffusion Characteristics in Lake Ontario
Horizontal Diffusion Characteristics Lake Ontario
2009/3/7
Experimental data on the diffusion of fluorescent dye patches were obtained in Lake Ontario, to study large-scale horizontal diffusion characteristics. In each experiment, a slug of water-soluble rhod...
Horizontal Divergence and Vorticity Estimates from Velocity and Temperature Measurements in the MODE Region
Horizontal Divergence MODE Region Vorticity Estimates
2009/3/7
Estimates of horizontal derivatives of velocity made by differencing velocity measurements are used to show that the observed velocity field due to low-frequency mesoscale motions during the prelimina...
An Experimental and Theoretical Study of the Turbulent and Laminar Convection Generated under a Horizontal Ice Sheet Floating on Warm Salty Water
Turbulent Horizontal Ice Sheet Floating Laminar Convection Generated Warm Salty Water
2009/3/7
In an experimental and theoretical study we model a phenomenon which occurs in the summer polar oceans; namely, the melting of flat sheets of either glacial ice or desalinated sea ice which float over...
On the Effects Of Horizontal Variability of Wind Stress on the Dynamics of the Ocean Mixed Layer
Horizontal Variability Ocean Mixed Layer Wind Stress
2009/2/18
The one-dimensional bulk mixed-layer model of Niiler (1975) is extended to two (or three) dimensions to take account of horizontal variation in wind stress on mixed-layer dynamics. Both surface stirri...
The Horizontal Coherency of the Motion of Summer Arctic Sea Ice
Horizontal Coherency Summer Arctic Sea Ice
2009/2/18
Four ice floes in the permanent arctic ice pack were instrumented during the summer of 1975. Spectral and cross-spectral analysis of the complex time series of the ice motion and of the surface winds ...
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...
Observations of the Horizontal Interactions between the Internal Wave Field and the Mesoscale Flow
Horizontal Interactions Internal Wave Field Mesoscale Flow
2009/2/10
Momentum and energy transfers from the mesoscale horizontal velocity shear to the internal wave field have been deduced from an analysis of a closely spaced, 25 km, moored current-meter array. The cor...
Effects of Horizontal Advection on Upper Ocean Mixing：A Case of Frontogenesis
Horizontal Advection Upper Ocean Mixing Frontogenesis
2009/2/10
The wind stress on the ocean surface induces horizontal advection and vertical mixing, two mechanisms which are capable of changing the surface water density. Advection and mixing can enhance or parti...
