Verification of Numerical Models of Lake Ontario: Part I. Circulation in Spring and Early Summer
Publisher: American Meteorological Society
Abstract: Data from the 1972 International Field Year on Lake Ontario have been used to test the performance of three-dimensional hydrodynamical models of large lakes. The models vary with regard to computational details, but their ...
Verification of Numerical Models of Lake Ontario. II. Stratified Circulations and Temperature Changes
Publisher: American Meteorological Society
Abstract: Data from the 1972 International Field Year on Lake Ontario are used to test the performance of three-dimensional hydrodynamic models of large lakes. This study is a sequel to a previous report concerning the quasi-homogeneous ...
Generation and Propagation of Downwelling Fronts
Publisher: American Meteorological Society
Abstract: The dynamics of downwelling fronts observed along the steep and elongated southern shore of Lake Ontario are investigated by considering the nonlinear response to surface forcing of one-layer and two-layer fluids on a ...
On the Joint Effect of Baroclinicity and Topography
Publisher: American Meteorological Society
Abstract: A simple two-layer model is constructed to illustrate the combined effect of baroclinicity and topography over an idealized continental slope region. It is shown that an assumed thermohaline circulation leads to topographic ...
The mean Circulation of Unstratified Water Bodies Drive by Nonlinear Topographic Wave Interactions
Publisher: American Meteorological Society
Abstract: A critical evaluation is presented of the conventional view that long-term mean circulation of homogeneous basins may be identified with the quasi-steady response of linear models to atmospheric forcing. Based on climatological ...
On the Theory of Atmospheric Development
Publisher: American Meteorological Society
Abstract: The baroclinic instability problem is formulated as an initial value problem to evaluate the effects of the initial configuration of the wave perturbation. The vertical shape of the initial perturbation is found to be as ...
The Nonlinear Dynamics of Cyclone Waves
Publisher: American Meteorological Society
Abstract: The development of atmospheric cyclones is studied from the viewpoint of the instability of large-scale wave perturbations superimposed on a zonal current. The stability properties of the observed mean January flow are ...
Topographic Response of Nearshore Currents to Wind: An Empirical Model
Publisher: American Meteorological Society
Abstract: Observations of winds and currents along the northshore of Lake Ontario are analyzed to evaluate effects of topographic wave propagation on wind-driven currents. Lagged cross-correlations and spectral transfer functions ...
Reliability of Circulation Models
Publisher: American Meteorological Society
Abstract: Current meter observations in Lake Ontario covering the 140-day period from 4 November 1982 to 23 March 1983 are used to evaluate the performance of circulation models for different time scales. The measurements were taken ...
