Fall 2013
An idealized process study is presented describing the cross-equatorial flow of grounded abyssal ocean currents in a differentially-rotating meridional channel with parabolic bottom topography. In particular we fully examine the dependence of the cross-equatorial volume flux on the underlying...

Fall 2013
The Kelvin-Helmholtz instability is the inertial destabilization of a parallel shear flow in a density stratified fluid under the influence of gravity. For example, this type of instability manifests itself as surface waves in the ocean when wind blows over the water surface. In this thesis we...

Nonlinear Evolution of Localized Internal Gravity Wave Packets: Theory and Simulations with Rotation, Background Flow, and Anelastic Effects
DownloadFall 2023
A series of three studies investigates theoretically and numerically the evolution, stability, and pseudomomentum transport of fully localized three-dimensional internal gravity wave packets, as they self-interact nonlinearly with their induced mean flow. The first study considers a rotating,...

Spring 2018
As internal gravity wavepackets propagate upward in the atmosphere, their amplitude experiences exponential growth so that nonlinear effects influence their evolution. This thesis examines the weakly and fully nonlinear evolution, stability, and overturning of horizontally and vertically...
