Surface wind modification near mid-latitude ocean fronts : observational and dynamical analysis

Creator:: O'Neill, Larry W.
Abstract:: Interactions between surface winds and meanders in mid-latitude sea surface temperature (SST) fronts with horizontal length scales of 100-1000 km are investigated from satellite observations and numerical simulations. Observations from the Sea- Winds scatterometer on the QuikSCAT satellite show that the magnitude, direction, curl, and divergence of the surface wind...

Numerical and assimilative studies of the equatorial Pacific cold tongue

Creator:: Perez, Renellys Christine
Abstract:: Numerical model and assimilation experiments were conducted in the tropical Pacific Ocean to obtain a better understanding of the processes that control the cold tongue surface mixed layer temperature balance during August 1999 to July 2004. The numerical model was first applied to test two hypotheses (asymmetric background currents and...

An empirical statistical model relating winds and ocean surface currents : implications for short-term current forecasts

Creator:: Zelenke, Brian Christopher
Abstract:: An empirical statistical model is developed that relates the non-tidal motion of the ocean surface currents off the Oregon coast to forecasts of the coastal winds. The empirical statistical model is then used to produce predictions of the surface currents that are evaluated for their agreement with measured currents. Measurements...

The reflection, transmission and scattering of internal waves at ocean fronts

Creator:: Stabeno, Phyllis Jean
Resource Type:: Dissertation
Full Text:: limited to those fronts which do not intersect the surface or bottom of the ocean. The model used here

Modeling studies of ocean circulation using inverse methods and bifurcation theory

Creator:: Vernieres, Guillaume
Abstract:: We present a study of the ocean circulation using state of the art numerical and data assimilation techniques. The second chapter of the thesis presents the development and application of generalized inversion to a simple dynamical model of Lake Kinneret. The intent was to develop the necessary tools to implement...

Field validation of a nearshore circulation model for alongshore-nonuniform flows

Creator:: Wilson, Gregory W.
Abstract:: We investigate, theoretically and experimentally, the problem of modeling depth-integrated (2DH) surf zone circulation on an alongshore-nonuniform natural beach, with waves approaching from an arbitrary angle. An approximate theoretical model is developed, which captures the important effect of advection in the alongshore dynamics, and shows that a nondimensional parameter Re[subscript]s...

Unstable jet flow along zonal ridge topography

Creator:: Witter, Donna Lynn
Abstract:: Motivated by observations of locally enhanced sea level variability near steep topographic slopes in regions of strong time-mean flows, effects of zonal ridge topography on zonal oceanic jet flow are investigated. Unstable wave properties and the dynamics of eddy-mean flow interaction are evaluated as a function of topographic geometry using...

Shear and convective turbulence in a model of thermohaline intrusions

Creator:: Mueller, Rachael
Abstract:: Thermohaline interleaving is an important mechanism for laterally fluxing salt, heat, and nutrients between oceanic water masses. Interleaving is driven by a release of potential energy resulting from the vastly differing diffusivities of heat and salt in seawater. The flows are composed of stacked intrusions that flux more buoyant and...

The time-averaged circulation of the north Pacific Ocean : an analysis based on inverse methods

Creator:: Zaron, Edward D.
Abstract:: The time-averaged velocity field in the North Pacific was estimated in two sets of inverse calculations. The planetary geostrophic equations were the basis for dynamical models of the flow in each case. The inverse estimates of the circulation were obtained by minimizing a positive-definite cost function, which measured the inconsistency...
