Le mouvement de l'air turbulent se manifeste sous forme de poussées momentanées et rapides qui peuvent présenter une orientation absolument quelconque. Parmi celles-ci, on peut distinguer : les rafales qui ne concernent que les variations de la vitesse horizontale du vent, sans modification de direction; les mouvements verticaux qui englobent tous les courants aériens ascendants ou descendants. 5, record 1, French, - courant%20descendant
Record number: 1, Textual support number: 1 OBS
Le terme «rabattant» semble employé par les pilotes pour décrire le phénomène de courant descendant lors du survol des régions montagneuses. Cependant, cette particularité n'est consignée dans aucune source. De plus, le terme «rabattant» est un terme de jargon. 6, record 1, French, - courant%20descendant

On a attribué longtemps la turbulence à la présence de «trous d'air», en fait il n'y a pas de «trous» dans l'air, la turbulence est généralement due à des déflections vers le haut ou vers le bas du vent horizontal. 7, record 1, French, - courant%20descendant

The microburst has a strong downflow descending very close to the ground. The ground turns the vertical winds into horizontal winds. The maximum horizontal extent of a microburst is on the order of 4 km in diameter but can be less than 1 km in diameter. Despite this small scale, an intense microburst can induce horizontal wind radials as high as 160 km/h. 5, record 3, English, - microburst

La microrafale est caractérisée par un fort courant descendant qui arrive très près du sol. En se rapprochant du sol, le vent vertical devient un vent horizontal. Le diamètre maximal de la microrafale est de l'ordre de 4 km, mais il arrive qu'il soit inférieur à 1 km. Malgré cette petite échelle, une microrafale de forte intensité produit des vents horizontaux pouvant atteindre 160 km/h. 4, record 3, French, - microrafale

Violent and damaging downdraught reaching the surface, associated with a severe thunderstorm. 2, record 4, English, - downburst
Record number: 4, Textual support number: 1 CONT
Downbursts occur in regions of a severe thunderstorm where the air is accelerated downward by exceptionally strong evaporative cooling occurs (a dry downburst) or by very heavy rain which drags dry air down with it (a wet downburst). When the rapidly descending air strikes the ground, it spreads outward in all directions in a circle, like a fast-running faucet hitting the sink bottom. Dr. Fujita has defined downbursts as a surface wind in excess of 62 km/hr (39 mph) caused by a small-scale downdraft from the base of a convective cloud. He further subdivided downbursts into two categories macrobursts and microbursts. 3, record 4, English, - downburst

Des rafales descendantes ou «avalanche d'air» sont également associés aux orages violents. Il s'agit de courants d'air descendants qui s'étendent lorsqu'ils touchent la surface du sol et produisent des vents directs pouvant atteindre jusqu'à 200 km à l'heure. Comme les tornades, les rafales descendantes peuvent causer des dommages considérables. De tels rafales produisent un bruit assourdissant, semblable à celui d'une tornade. 5, record 4, French, - rafale%20descendante
