The Spectrum of Nearly Inertial Turbulence in a Stably Stratified Fluid
Publisher: American Meteorological Society
Abstract: The assumptions leading to the classical inertial subrange spectral forms are critically examined. It is shown how, by slightly relaxing the assumptions, a form can be obtained for the spectrum in the presence of other ...
A Sharp Cutoff Spectral Differentiator
Publisher: American Meteorological Society
Abstract: Design data and experimental results are presented for an eight-pole optimally flat filter which makes available the first seven derivatives of the filtered input signal.
Wave-Turbulence interactions in the Upper Ocean. Part I: The Energy Balance of the Interacting Fields of Surface Wind Waves and Wind-Induced Three-Dimensional Turbulence
Publisher: American Meteorological Society
Abstract: We analyze in detail the budget of total and fluctuating energy in the surface layer of the ocean. We suggest a rational scheme for separating the budget of turbulence from that of random wind-generated surface waves, and ...
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 ...
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 ...
