Air–Water Momentum Flux Observations over Shoaling waves
Publisher: American Meteorological Society
Abstract: This paper drab, with simultaneous momentum flux observations from four towers placed at different depths along a shore-normal line at the west end of Lake Ontario, Canada. The towers were at nominal depths of 12, 8, 4, ...
Nonstationary Analysis of the Directional Properties of Propagating Waves
Publisher: American Meteorological Society
Abstract: It is proposed that the sea surface be studied in a way that takes into account the observed groupiness of wind-generated waves. A new method of analysis to study the directional properties of the surface is developed. It ...
Deep-Water Field Evaluation of the NDBC-SWADE 3-m Discus Directional Buoy
Publisher: American Meteorological Society
Abstract: This paper presents the results of an experiment designed to assess the directional spectrum resolution qualities of the pitch-roll-heave National Data Buoy Center-Surface Wave Dynamics Experiment (NDBC-SWADE) 3-m discus ...
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 ...
Riding the Crest: A Tale of Two Wave Experiments
Publisher: American Meteorological Society
Abstract: This paper gives a general overview of two ocean wave experiments. The experimental goals of the Surface Wave Processes Program (SWAPP) and of the Surface Wave Dynamics Experiment (SWADE) are quite different but complementary. ...
Estimating Sea Spray Volume with a Laser Altimeter
Publisher: American Meteorological Society
Abstract: own-looking laser altimeters are commonly used to measure the sea surface elevation. However, because the laser radiation is attenuated by spray droplets suspended along the transmission path, it is presumed that altimeters ...
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 ...
Measurement of Directional Wave Spectra Using Aircraft Laser Altimeters
Publisher: American Meteorological Society
Abstract: A remote sensing method to measure directional oceanic surface waves by three laser altimeters on the NOAA LongEZ aircraft is investigated. To examine feasibility and sensitivity of the wavelet analysis method to various ...
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 ...
