turbulence
TUR-byuh-luhns
/ˈtɜː.bjə.ləns/
Violent or unsteady movement of air or water, or of some other fluid.
Refers to chaotic, stochastic fluid motion characterized by rapid pressure and velocity changes.
The story behind the word. The word traces back to the Latin 'turba', which meant a crowd, brawl, or noisy confusion. Just as a rowdy crowd moves unpredictably and chaotically, turbulent water or air swirls in a wild, disorganized fashion.
Word relationships
- instability: Instability is a state of being prone to change, while turbulence is the active, chaotic motion itself.
- commotion: Commotion is general noisy confusion, whereas turbulence is specifically fluid or aerodynamic chaos.
- calm: Calm implies complete stillness, whereas laminar flow is moving but highly organized.
- tranquility: Tranquility is a peaceful state of mind or environment, not a fluid dynamic state.
Commonly confused with
- disturbance: A disturbance can be a single interruption, whereas turbulence is a continuous state of chaotic fluid mixing.
Word family
- turbulent (adjective): Characterized by conflict, disorder, or confusion; not controlled or calm.
- turbulently (adverb): In a wild, chaotic, or unsteady manner.
Collocations
- severe turbulence
- encounter turbulence
- atmospheric turbulence
- clear-air turbulence
Example sentences
- "The airplane encountered severe turbulence while flying over the Rocky Mountains, causing the cabin to shake violently." Aviation experience
- "Atmospheric turbulence is often invisible to the naked eye, making it difficult for pilots to avoid without radar." Meteorological report
Memory hook
Think of a 'turbulent' crowd at a 'turbo' charged rock concert, pushing and swirling in all directions. Turbulent = Turbo-violent crowd.
When not to use
Avoid using in purely static contexts; it requires active, chaotic motion.
Fun facts
- Artist Vincent van Gogh accurately captured the mathematical structures of fluid turbulence in his famous painting 'The Starry Night' during a period of intense personal crisis.
