A Wave Torn Apart —Chris Howland (University of Cambridge)

The turbulent breakdown of an internal gravity wave in a sinusoidal shear flow. The wave is refracted by the shear, leading to a turbulent transition through a combination of convective and shear instabilities. Local kinetic energy dissipation rate is visualised on a log-scale using a cmocean colour map.
