vorticity

Definition

A measure of the local spinning motion of a fluid at any point in a flow, representing the tendency of elements of the fluid to rotate.

Etymology

Derived from the Latin 'vortex', meaning a whirlpool or eddy, combined with the suffix '-ity' to denote a state or quality. It entered scientific terminology to describe the rotational characteristics of fluid dynamics.

In the news

The article mentions that gradients in vorticity, along with the Coriolis effect, help govern how large atmospheric motions like the hexagonal jet stream form and maintain their shape on Saturn.

Saturn has a six-sided storm system wider than Earth, and scientists still cannot fully explain why its perfect shape refuses to disappear
