Turbulence comes in bursts in stably stratified flows
There is a clear distinction between simple laminar and complex turbulent fluids; however, in some cases, as for the nocturnal planetary boundary layer, a stable and well-...- publication PDF

How waviness in the circulation changes surface ozone: A viewpoint using...
Local finite-amplitude wave activity (LWA) measures the waviness of the local flow. In this work we relate the anticyclonic part of LWA, AWA (anticyclonic wave activity), to...- publication PDF
