Mixing depth. The thickness of the atmospheric layer near the surface in which air pollutants are dispersed by turbulence. At the top of the mixing layer a barrier to the dispersion is often formed by a temperature inversion. 5, record 1, English, - mixed%20layer

[Ce modèle] se caractérise en particulier par la prise en compte non plus d'un certain nombre de couches arbitrairement désignées, mais par la caractérisation de trois couches ayant une existence physique : une couche de surface, comprise entre le sol et la couche de mélange et dans laquelle existent des phénomènes tels que dépôt sec, qui affectent le profil vertical des polluants - une couche de mélange s'étendant jusqu'à la couche d'inversion - une couche d'inversion au-dessus de la couche de mélange. 7, record 1, French, - couche%20de%20m%C3%A9lange

The region from the surface of the earth to an altitude of about 12 km is called the troposphere. In this region most of the earth's weather features appear, and the majority of the atmospheric mixing occurs. 3, record 2, English, - atmospheric%20mixing

Les concentrations de polluants sont réduites par le mélange atmosphérique, lequel dépend d'un certain nombre de conditions météorologiques comme la température, la vitesse du vent, ainsi que le mouvement des systèmes de pression haute et basse et leur interaction avec la topographie locale, par exemple les montagnes et les vallées. 3, record 2, French, - brassage%20de%20l%26rsquo%3Bair
