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.
