Title: Comparing Stokes drift for internal and surface gravity wave packets
Abstract:
Although the leading-order motion of waves is periodic (in other words backwards and forwards) many types of waves, including those driven by gravity, induce a mean flow as a higher-order effect. Because they transport energy, momentum and other tracers, wave-induced mean flows have important consequences for climate, environment, air traffic, fisheries, offshore oil and other industries. I compare and contrast existing and new results for the Stokes drift and associated return flow for surface gravity wave packets on an unstratified fluid to new results for the Stokes drift and its "return flow" for Boussinesq internal gravity wave packets on a linearly stratified fluid. I do so by exploring a perturbation expansion in two small parameters, the steepness and the bandwidth of the packet, and provide numerical and experimental validation.
Bio:
Dr Ton van den Bremer is a Chancellor's Fellow at the University of Edinburgh (since October 2015). His research focusses on geophysical fluid mechanics ranging from oceanic and atmospheric waves to buoyancy driven flow. Ton has previously worked as a post-doctoral research associate the VU University Amsterdam and an Adjunct Lecturer in Environmental Economics at Amsterdam University College (2015). Ton holds a DPhil in Engineering Science from the University of Oxford (2015), where his thesis examines mean flows induced by gravity waves in geophysical applications. He was College Lecturer at Keble College (2013-2014). He holds an MEng in Engineering from Imperial College London (2009) and an MPhil in Economics from the University of Oxford (2011).
