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. Blow-up of subsurface vorticity waves in the ocean under strong winds. Presented at EGU General Assembly 2019, Online

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.
