  • An Anisotropic Subgrid-Scale Parameterization for Large-Eddy Simulations of Stratified Turbulence 

    Khani, Sina; Waite, Michael L (AMS, 2020-10-01)
    Subgrid-scale (SGS) parameterizations in atmosphere and ocean models are often defined independently in the horizontal and vertical directions because the grid spacing is not the same in these directions (anisotropic ...
  • Resolution Dependence and Subfilter-Scale Motions in Idealized Squall-Line Simulations 

    Lai, Kwan Tsaan; Waite, Michael L (AMS, 2020-07-08)
    In this paper, the sensitivity of idealized squall-line simulations to horizontal resolution, subgrid turbulence mixing scheme, and subfilter-scale motion is discussed. Inconsistent results from numerical simulations ...
  • Normal Mode Spectra of Idealized Baroclinic Waves 

    Ambacher, Matthew R.; Waite, Michael L (AMS, 2020-02-01)
    Normal modes are used to investigate the contributions of geostrophic vortices and inertia–gravity waves to the energy spectrum of an idealized baroclinic wave simulation. The geostrophic and ageostrophic modal spectra ...
  • Realizing Surface-Driven Flows in the Primitive Equations 

    Bembenek, Eric; Poulin, Francis J.; Waite, Michael L (AMS, 2015-05-01)
    The surface quasigeostrophic (SQG) model describes flows with surface buoyancy perturbations with no interior quasigeostrophic potential vorticity at small Rossby number Ro and O(1) Burger number, where quasigeostrophic ...
  • Dependence of Model Energy Spectra on Vertical Resolution 

    Waite, Michael L (AMS, 2016-04-01)
    Many high-resolution atmospheric models can reproduce the qualitative shape of the atmospheric kinetic energy spectrum, which has a power-law slope of −3 at large horizontal scales that shallows to approximately −5/3 in ...
  • Topographically generated internal waves and boundary layer instabilities 

    Soontiens, Nancy; Stastna, Marek; Waite, Michael L (AIP, 2015-01-06)
    Flow over topography has been shown to generate finite amplitude internal waves upstream, over the topography and downstream. Such waves can interact with the viscous bottom boundary layer to produce vigorous instabilities. ...
  • Random forcing of geostrophic motion in rotating stratified turbulence 

    Waite, Michael L (AIP, 2017-12-29)
    Random forcing of geostrophic motion is a common approach in idealized simulations of rotating stratified turbulence. Such forcing represents the injection of energy into large-scale balanced motion, and the resulting ...
  • Wall turbulence response to surface cooling and formation of strongly stable stratified boundary layers 

    Atoufi, Amir; Scott, K. Andrea; Waite, Michael L (AIP, 2019-08-20)
    This paper investigates the processes by which stable boundary layers are formed through strong surface cooling imposed on neutrally stratified wall-bounded turbulence using high-resolution direct numerical simulation at ...
  • Synchronization of Complex-Valued Dynamical Networks 

    Shen, Yuan (University of Waterloo, 2021-09-27)
    Dynamical networks (DNs) have been broadly applied to describe natural and human systems consisting of a large number of interactive individuals. Common examples include Internet, food webs, social networks, neural networks, ...
  • Backscatter in stratified turbulence 

    Khani, Sina; Waite, Michael L (Elsevier, 2016-11)
    In this paper, kinetic and potential energy transfers around a spectral test fil ter scale in direct numerical simulations of decaying stratified turbulence are studied in both physical and spectral domains. It is shown ...
  • Prandtl number dependence of stratified turbulence 

    Legaspi, Jesse D.; Waite, Michael L (Cambridge, 2020-09-21)
    Stratified turbulence has a horizontally layered structure with quasi-two-dimensional vortices due to buoyancy forces that suppress vertical motion. The Prandtl number Pr quantifies the relative strengths of viscosity ...
  • Coupled models of structured contagion processes in human-environment systems 

    Jentsch, Peter Carl (University of Waterloo, 2021-09-15)
    Models of infectious processes are a common feature in the landscape of applied mathematics. It is rare that these processes are isolated from other significant dynamics in nature, and therefore we can incorporate some of ...
  • Universe Beyond Inflation and ΛCDM 

    Kim, Hyung Jin (University of Waterloo, 2021-09-09)
    The current paradigm of universe, $\Lambda CDM$ model with an early phase of inflation, has been quite successful in describing our universe in a simple manner, yet matching well with the observational evidence. This model ...
  • Effects of a Geostrophic Current on the Propagation and Generation of Internal Tides 

    He, Yangxin (University of Waterloo, 2021-08-30)
    Internal tides (ITs) are ubiquitous in a stratified ocean where they are generated in response to tidal flows incident upon bottom topography. Along-shelf currents or boundary currents are ocean currents commonly observed ...
  • Mathematical modelling of supraglacial meltwater production and drainage 

    Hill, Tim (University of Waterloo, 2021-08-30)
    Mountain glaciers and the polar ice sheets exert a critical control on water resource availability, drive sea level change, and impact global ocean circulation. These and other impacts are controlled by surface meltwater ...
  • A Comparative and Exploratory Study of Homogeneous and Inhomogeneous Stratified Turbulence 

    Siewnarine, Dinesh (University of Waterloo, 2021-08-25)
    The study of turbulence in the oceans and atmosphere is far-flung and ever-reaching in the academic world with research being done theoretically, experimentally and numerically. With great strides in the increasing power ...

    Kim, Jungjoon Leo (University of Waterloo, 2021-08-25)
    Over the last couple of decades, cosmology has become an exciting area to study. Technological developments in both the computational and observational fronts have propelled cosmology into the limelight of modern physics. ...

    Hanson, Taylor (University of Waterloo, 2021-08-24)
    An abundance of evidence exists to support the notion of annual winter blooms of phytoplankton, particularly diatoms, persistent in the surface waters of freshwater lakes located in temperate and boreal climatic zones. ...
  • A Floating Ball and Two Asymptotic Problems in Capillarity 

    Chen, Hanzhe (University of Waterloo, 2021-06-02)

    Skanes-Norman, Joshua (University of Waterloo, 2021-05-27)
    In this thesis, we are concerned with the problem of characterizing noise associated with implementations of quantum circuits. We first explore the notion of error rates of quantum circuits and argue that the semantic ...
