To get an insight into dynamics of the oceanic surface boundary layer we develop an asymptotic model of nonlinear dynamics of linearly decaying three-dimensional long10 wave perturbations in weakly stratified boundary layer flows. Although in nature... Read More about A novel (2+1)d nonlinear evolution equation for weakly stratified free surface boundary layers.

Collapses of linearly decaying three-dimensional perturbations in homogeneous and weakly stratified boundary layers (2020)
Thesis
Oloo, J. Collapses of linearly decaying three-dimensional perturbations in homogeneous and weakly stratified boundary layers. (Thesis)

The physical mechanisms of why an orderly laminar flow suddenly becomes turbulent are still poorly understood, despite more than a century of incessant efforts. The thesis puts forward a radically new approach to understanding the fundamental challen...

We study the nonlinear dynamics of localized perturbations of a confined generic boundary-layer shear flow in the framework of the essentially two-dimensional generalization of the intermediate long-wave (2d-ILW) equation. The 2d-ILW equation was ori... Read More about Boundary layer collapses described by the two-dimensional intermediate long-wave equation.

Blow-up of subsurface vorticity waves in the ocean under strong winds (2019)
Presentation / Conference Contribution
Oloo, J., & Shrira, V. (2019). Blow-up of subsurface vorticity waves in the ocean under strong winds. Geophysical Research Abstracts, 21,

Understanding mixing in the uppermost part of the water column is crucial for modelling air-sea interaction. Specific mechanisms of mixing under strong wind conditions are poorly understood. Under strong winds entrainment of air bubbles into the wate... Read More about Blow-up of subsurface vorticity waves in the ocean under strong winds.
