Vortex dynamics in cylindrical containers encapsulate a range of complex fluid behaviours driven by rotational motion. In these geometries, the interplay between centrifugal forces and viscous effects ...

Roughly twenty miles above Earth's surface, in a largely invisible layer of the atmosphere called the stratosphere, some of the most dramatic temperature changes on our planet unfold. Major sudden ...

When the polar vortex stumbles, the weather at ground level can pivot from mild to brutal in a matter of days. A circulation that usually spins quietly above the pole can suddenly send lobes of Arctic ...
