turbulence

(turbulent flow)
(irregular flow of a fluid)

Turbulence (or turbulent flow) is chaotic flow of a fluid. It is characterized by changes in flow velocity and pressure over space and time, and eddies, i.e., circular or swirling flows, often lasting only a short time.

Turbulence is in contrast to laminar flow in which fluid flows in continuous lines.

Turbulence in the atmosphere is a contributor to seeing and can be detected in gases, e.g., in stars or clouds through the analysis of spectral lines.
