Lab-based mini-atmosphere reveals how turbulence changes on different scales

With a new lab-based experiment, researchers in the UK and France have recreated the characteristic cascades of energy and angular momentum that underpin key features of Earth's atmosphere. Reporting in Physical Review Letters, a team led by Peter Read at the University of Oxford has gained fresh insights into how energy fluctuations in turbulent flows are linked to their size, while also uncovering behaviors that current atmospheric models can't yet explain.
