Kinematics of Turbulence Convected by a Random Wave Field
Publisher: American Meteorological Society
Abstract: Turbulent velocity spectra measured beneath wind waves show a large enhancement about the central wave frequency. A ?5/3" frequency dependence can be seen both above and below the central peak, but with an apparent increase ...
Oceanic Turbulence Dissipation Measurements in SWADE
Publisher: American Meteorological Society
Abstract: Recent experiments measuring turbulence dissipation rates in the upper ocean can be divided into two types: those supporting an analogy between the upper ocean and lower atmosphere, with dissipation rates following wall ...
Wave-Turbulence Interactions in the Upper Ocean. Part II. Statistical Characteristics of Wave and Turbulent Components of the Random Velocity Field in the Marine Surface Layer
Publisher: American Meteorological Society
Abstract: We present the results of an analysis of field data collected by Donelan who used a miniature drag sphere to measure velocities beneath wind waves on Lake Ontario. Linear statistical techniques are used to separate the ...
Directional Wave Spectra from a Swath Ship at Sea
Publisher: American Meteorological Society
Abstract: During the Surface Wave Dynamics Experiment (SWADE), the swath ship Frederick G. Creed was equipped with an array of wave staffs for the estimation of wave directional spectra. This paper reports on the first such estimates ...
Estimates of Kinetic Energy Dissipation under Breaking Waves
Publisher: American Meteorological Society
Abstract: The dissipation of kinetic energy at the surface of natural water bodies has important consequences for many Physical and biochemical processes including wave dynamics, gas transfer, mixing of nutrients and pollutants, and ...
Three-Dimensional Mapping of Fluorescent Dye Using a Scanning, Depth-Resolving Airborne Lidar
Publisher: American Meteorological Society
Abstract: Results are presented from a pilot study using a fluorescent dye tracer imaged by airborne lidar in the ocean surface layer on spatial scales of meters to kilometers and temporal scales of minutes to hours. The lidar used ...
