fluid structure interaction immersed boundary method VOS unstructured grids finite volume method
2011/9/9
This paper presents an improved unstructured grid immersed boundary method. The advantages of both immersed boundary method and body fitted grids which are generated by unstructured grid technology ar...
Surface flow structure of the Gulf Stream from composite imagery and satellite-tracked drifters
Surface flow structure Gulf Stream composite imagery satellite-tracked drifters
2009/11/16
A unique set of coutemporaneous satellite-tracked drifters and five-day composite Advanced Very High Resolution Radionmeter (AVHRR) satellite imagery of the North Atlantic has been analyzed to examine...
Double-Diffusive Convection and its Implications for the Temperature and Salinity Structure of the Ocean and Lake Vanda
Double-Diffusive Convection Salinity Structure Temperature Lake Vanda
2009/4/3
Recently, Fedorov has attempted to interpret some temperature and salinity profiles in the northeast Atlantic, as reported by Zenk, in terms of the results of laboratory experiments in double-diffusiv...
Laboratory Measurement of Heat Transfer and Thermal Structure Near an Air-Water Interface
Laboratory Measuremen Air-Water Interface Thermal Structure Near Heat Transfer
2009/4/3
Experiments have been conducted in a wind-water tunnel to establish a quantitative relationship between wind profile parameters, heat flux through the air-water interface, and the temperature differen...
Thermohaline Structure and Baroclinic Flow Across the Gulf of California Entrance and in the Revilla Gigedo Islands Region
Thermohaline Structure Gulf of California Entrance Baroclinic Flow Revilla Gigedo Islands Region
2009/4/3
The thermohaline structure, vertical stability and baroclinic flow between the Gulf of California entrance and the Revilla Gigedo islands are investigated by means of closely spaced salinity and tempe...
Spectra of Internal Waves：In-Situ Measurements in a Multiple-Layered Structure
Internal Waves Multiple-Layered Structure In-Situ Measurements
2009/4/3
The persistence of layering between 200 and 400 m depth in the Arctic Ocean has enabled construction of accurate internal wave amplitude traces from a 30-hr series of successive temperature profiles t...
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...
Observation of the Structure on Moving Gust Patterns Over a Water Surface (“Cat's Paws”)
Moving Gust Patterns Water Surface
2009/4/2
We report on observations of near-surface Velocity, temperature, stress, buoyancy, and surface wave fluctuations, including successive short-time averages of coherences, phases, autospectra, and proba...
The Effect of Internal Wave Strain on Vertical Spectra of Fine-Structure
Internal Wave Strain Fine-Structure Vertical Spectra
2009/4/2
Vertical spectra of temperature perturbations are due to (i) internal wave displacement in the mean profile and (ii) fine-structure that would still be measured in the absence of internal waves. The f...
Interpretation of Internal Wave Measurements in the Presence of Fine-Structure
Internal Wave Measurements Fine-Structure
2009/3/26
Philips has pointed out that the measurement of the internal wave spectrum and coherence in a stratified medium is distinctly altered when the profile contains fine-scale layers. Garrett and Munk demo...
Fine-Structure Contamination of Moored Temperature Sensors：A Numerical Experiment
Fine-Structure Contamination A Numerical Experiment Moored Temperature Sensors
2009/3/24
Using an inverse fast Fourier transform technique, numerical calculations have been made in order to study the contamination of moored temperature measurements of internal waves by passive temperature...
The Structure and Dynamics of the Ocean Surface Mixed Layer
Structure Dynamics Ocean Surface Mixed Layer
2009/3/24
The present paper describes a one-dimensional unsteady model of the ocean surface mixed layer. The model somewhat resembles the approach of Munk and Anderson in that the differential equations for mea...
Internal Wave Spectra in the Presence of Fine-Structure
Internal Wave Spectra Fine-Structure
2009/3/9
Phillips has shown that an undulating motion of a layered medium relative to a measuring instrument will result in a σ−2 spectrum (frequency or wavenumber) over a bandwidth determined by the thi...
Structure of Wind-Driven Equatorial Currents in Homogeneous Oceans
Wind-Driven Equatorial Currents Homogeneous Oceans
2009/3/9
The properties of wind-driven equatorial currents in homogeneous oceans are investigated for variable wind stresses and variable eddy viscosities. In the case of a uniform westward stress, the calcula...
Currents at 25 m at 13.14N, 59.20W were measured from 2 July 1968 through 30 August 1968. The current meter was attached to a stable spar buoy and the position of the buoy monitored with radar based o...
