Dispersion of Floatables in Lake Currents
Publisher: American Meteorological Society
Abstract: A group of ten sub-surface drogues were released in a cluster in the epilimnion 15 km offshore near Oshawa, Lake Ontario, and the subsequent drift and horizontal spread were followed for 72 h using the radar/decca navigation ...
On the Mean Path of a Buoyant Chimney Plume in Non-Uniform Wind
Publisher: American Meteorological Society
Abstract: Based on the turbulent entrainment hypothesis of Morton et al. and the eddy diffusivity hypothesis, approximate theories have been developed for the rise of a buoyant chimney plume in the atmospheric boundary layer, ...
Horizontal Diffusion Characteristics in Lake Ontario
Publisher: American Meteorological Society
Abstract: 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 rhodamine dye solution was ...
Observations of Lateral Shear in the Nearshore Zone of a Great Lake
Publisher: American Meteorological Society
Abstract: Observations of currents across a nearshore zone from 2 to 6 km offshore indicate that unsteady longshore flow and complete reversals in flow are usually accompanied by large values of lateral shear. These values often ...
Experimental Studies of Relative Diffusion in Lake Huron
Publisher: American Meteorological Society
Abstract: Experimental data were obtained in Lake Huron on the distribution of mean concentration and meansquare fluctuation about the center of gravity of a diffusing plume of fluorescent dye. Some of the mean concentration profiles ...
Structure of the Flow within the Coastal Boundary Layer of the Great Lakes
Publisher: American Meteorological Society
Abstract: Properties of the nearshore flow have been observed in some detail in Douglas Point, Lake Huron. Time series flow data obtained from a network of current meters deployed in a coastal chain perpendicular to the local shoreline ...
Coastal Boundary Layer Characteristics during Summer Stratification in Lake Ontario
Publisher: American Meteorological Society
Abstract: Simultaneous measurements of Eulerian and Lagrangian currents along the north shore of Lake Ontario are analyzed to provide the mean flow properties and horizontal turbulent exchange characteristics in the coastal boundary ...
Comparative Analysis of Spectral, Empirical Orthogonal Function, and Wavelet Decompositions for an Upwelling Event
Publisher: American Meteorological Society
Abstract: The recently developed wavelet transform, conventional spectral, and empirical orthogonal function decompositions have been applied to the vertical temperature profiles characterized with an isolated upwelling event and ...
Probability Distribution of Concentrations Measured in the Wake of a Continuous Point Source in Coastal Currents
Publisher: American Meteorological Society
Abstract: A generalized statistical model is proposed to determine the probability density function of the concentration history measured at a fixed point in the wake of a continuous point source in coastal currents. An application ...
