A circular pattern of air current created by the movement of an airfoil through the air when the airfoil is generating lift. 4, record 2, English, - wing%2Dtip%20vortex
Record number: 2, Textual support number: 1 OBS
As an airfoil moves through the atmosphere in sustained flight, an area of high pressure is created beneath it and an area of low pressure is created above it. The air flowing from the high-pressure area to the low-pressure area around and about the tips of the airfoil tends to roll up into two rapidly rotating vortices, cylindrical in shape. These vortices are the predominant parts of aircraft wake turbulence and their rotational force is dependent upon the wing loading, gross weight, and speed of the generating aircraft. The vortices from medium to heavy aircraft can be of extremely high velocity and hazardous to smaller aircraft. 4, record 2, English, - wing%2Dtip%20vortex

Record number: 2, Textual support number: 1 OBS
Lorsqu'un tel profil est déplacé de façon continue dans l'atmosphère, une zone de haute pression se crée à l'intrados et une autre de basse pression se crée sur l'extrados. L'air qui circule autour des ailes, de la zone de haute pression vers celle de basse pression, a tendance à former deux tourbillons cylindriques en rotation rapide. Ces tourbillons produisent la majeure partie de la turbulence de sillage d’un aéronef. La force de rotation de ces tourbillons dépend de la charge alaire, de la masse brute et de la vitesse de l'aéronef. Les tourbillons provoqués par les aéronefs moyens et lourds peuvent être caractérisés par de très grandes vitesses et mettre en danger les aéronefs plus petits. 5, record 2, French, - tourbillon%20en%20bout%20d%27aile

Panaches horizontaux. Lorsque la température augmente en fonction de l'altitude, l'air est stable et il n’ existe aucune turbulence verticale. Le brassage horizontal n’ est pas aussi fort que dans les panaches coniques, mais il est toutefois existant. Le panache s’étale donc à l'horizontale, mais peu, sinon aucunement, à la verticale. Comme les vents sont habituellement légers, le panache suit aussi une trajectoire sinueuse à l'horizontale. La concentration des polluants dans les panaches est grande, mais peu d’émissions de sources élevées sont rabattues au sol dans cette situation, sauf lorsque l'inversion est dissipée due à un réchauffement en surface, ou lorsque le terrain monte à la hauteur du panache.

[...] la circulation aux latitudes moyennes est caractérisée par des séquences transitoires creux-crête-creux-onde très importantes. C’est ce qu’on appelle les «ondes de Rossby», d’après Carl-Gustave Rossby, qui a élaboré sa théorie en 1937. Les ondes de Rossby sont principalement inclinées du nord-est au sud-ouest dans l’hémisphère Nord. [...] Les ondes planétaires sont les ondes de Rossby [...] Les crêtes ont tendance à se former au-dessus de grandes chaînes de montagne, comme les Rocheuses, et au-dessus de surfaces constamment chaudes.

Le scintillement des étoiles [...] est produit par les déplacements d’air dans l'atmosphère terrestre. On peut voir cet effet à bien d’autres endroits. Par exemple, si vous regardez le long d’une route longue et chaude par une belle journée d’été, vous allez voir les objets au loin miroiter. L'air chaud se déplaçant vers le haut se mêle à l'air froid, un peu comme de l'eau bouillante dans une casserole. Ceci cause de la turbulence dans l'air. [...] Dans le cas des étoiles, le scintillement est causé parce que la chaleur accumulée dans le sol au cours de la journée(le soleil réchauffe le sol) est libérée graduellement durant la nuit. L'air près du sol reçoit cette chaleur et s’élève à la rencontre de l'air plus froid. L'air chaud et l'air froid se mélangent, créant ainsi de la turbulence. [...] Le scintillement des étoiles se manifeste de deux façons. D'abord, l'éclat de l'étoile change rapidement.

tourbillon en bout d’aile; tourbillon d’extrémité d’aile : Courant d’air circulaire créé par le déplacement d’un profil générateur de portance. Lorsqu'un tel profil est déplacé de façon continue dans l'atmosphère, une zone de haute pression se crée à l'intrados et une autre de basse pression se crée sur l'extrados. L'air qui circule autour des ailes, de la zone de haute pression vers celle de basse pression, a tendance à former deux tourbillons cylindriques en rotation rapide. Ces tourbillons produisent la majeure partie de la turbulence de sillage d’un aéronef. La force de rotation de ces tourbillons dépend de la charge alaire, de la masse brute et de la vitesse de l'aéronef. Les tourbillons provoqués par les aéronefs moyens et lourds peuvent avoir de très grande vitesse et mettre en danger les aéronefs plus petits. 4, record 26, French, - turbulence%20cr%C3%A9%C3%A9e%20par%20les%20tourbillons

Cette conduction agit de manière efficace lorsqu'il y a de la turbulence. Si la turbulence est nulle(de nuit avec vent calme), la conduction est très faible. Mais s’il y a du vent, la turbulence accroît la conduction. Cependant en cas de refroidissement du sol, celui-ci n’ est transmis qu'aux très basses couches de l'atmosphère, ce qui exige un minimum de turbulence(vent faible).

De petites quantités d’air se mélangent habituellement à la suspension lorsqu'on l'agite ou qu'elle tombe dans un cuvier. La plupart des problèmes sont cependant dus à la fosse à eaux blanches. L'eau qui s’écoule librement de la zone de formation sur la toile tombe dans des bacholles de récupération qui canalisent l'eau blanche vers une fosse placée soit sous la toile, soit du côté transmission de la machine. L'eau blanche récupère inévitablement une certaine quantité d’air; un temps de séjour relativement long dans un canal découvert est souhaitable pour que l'air puisse s’échapper et que la turbulence se dissipe avant qu'on ne mélange les eaux de la fosse sous toile avec le reste de la suspension. 1, record 38, French, - entra%C3%AEnement%20de%20l%27air

Roughness length z0 is a measure of the roughness of the surface. It is not normally measured directly, but is defined as the height at which the wind speed becomes zero.

La hauteur de mélange correspond à l'épaisseur de la couche atmosphérique près du sol dans laquelle les polluants peuvent se disperser en quelques heures. Deux principaux mécanismes permettent aux polluants de se disperser rapidement dans la verticale : la turbulence thermique et la turbulence mécanique. La turbulence thermique se produit lorsque l'air est moins dense près du sol, par exemple lors d’une journée ensoleillée et chaude. La turbulence mécanique est due à la variation verticale du vent et elle augmente lorsque les vents sont forts et que la surface du sol est rugueuse. Le programme d’Environnement Canada qui estime la hauteur de mélange, [...] comporte maintenant certains paramètres d’ajustement, dont le principal est celui de la longueur de rugosité. La valeur de ce paramètre dépend de l'environnement dans un rayon de 5 km du site modélisé. Par exemple, la longueur de rugosité en milieu fortement urbanisé est d’environ 1 m, tandis qu'elle est de quelques centimètres au-dessus de surfaces gazonnées. Il est important de noter que les vitesses de vent aux stations météorologiques synoptiques(situées dans les aéroports) sont généralement mesurées au-dessus de surfaces dont la longueur de rugosité est petite(quelques cm). Si les vents étaient mesurés au-dessus de surfaces très rugueuses, leurs valeurs seraient beaucoup plus faibles. 4, record 40, French, - longueur%20de%20rugosit%C3%A9
