La vitesse du vent subit des oscillations, irrégulières et très rapides(20 à 25 par min.), qui montrent que l'écoulement de l'air n’ est pas laminaire, mais tourbillonnaire, ou encore turbulent. L'ensemble des tourbillons de toute échelle qui existent dans l'atmosphère constitue la turbulence atmosphérique. 3, record 2, French, - turbulence%20atmosph%C3%A9rique

A random exchange of fluid parcels on any scale from the molecular to the largest eddy. The presumption of randomness implies that any conservative property within the area of mixing is equalized and the gradient thereof is destroyed. The process of mixing is thus irreversible; turbulence enlarges the scale of the mixing parcels and thereby increases the rate of mixing. 2, record 3, English, - mixing

La turbulence atmosphérique dans les basses couches de l'atmosphère ou «mouvement tourbillonnaire» est le mécanisme qui réalise pratiquement la diffusion atmosphérique. Elle provoque un mélange intense des diverses couches d’air dans toutes les directions, ce qui entraîne la dilution de la parcelle d’air polluée et par conséquent la diminution de sa teneur en polluant. 3, record 3, French, - m%C3%A9lange

When an object is so shaped that the layers of fluid just described cannot flow in smooth streams but instead are deflected so abruptly that they break up into disorganized whorls, the irregular mess of swirling fluid thus created is called "turbulence", and is often referred to as "eddy drag". 1, record 4, English, - turbulence

Quand la forme d’un objet ne permet pas aux couches fluides de couler régulièrement, mais provoque une brusque rupture du courant et le sépare en tourbillons, on appelle le fluide tourbillonnaire «turbulence» ou, plus communément, «traînée de turbulence». 1, record 4, French, - turbulence
