Thermal stratification of the atmosphere is characteristic of the Nocturnal Boundary Layer(NBL), particularly in basin topography where surface cooling combines with drainage flows from competing sources to create a complex thermal structure that can play an important role in transport and diffusion of pollution. 5, record 1, English, - thermal%20stratification

Atmospheric stability describes the thermal stratification or vertical temperature structure of the atmosphere. Generally, six or seven different classes of atmospheric stability are used to describe the atmosphere. These classes range from extremely unstable (when atmospheric turbulence is greatest) to extremely stable (when atmospheric mixing is at a minimum and wind speeds are low). When the atmosphere is unstable, pollutants can rapidly diffuse through a large volume of the atmosphere. When the atmosphere is stable, pollutants will diffuse much more slowly in a vertical direction 6, record 1, English, - thermal%20stratification

L'inversion de température [...] affecte les 50 premiers mètres de la troposphère. Avec la nuit, surtout en hiver, le sol se refroidit plus rapidement que les couches d'air. Au cours de la nuit les premières couches d'air vont peu à peu devenir plus froide que celle située au dessus, la stratification thermique (plus on monte, plus il fait froid) est donc inversée. 4, record 1, French, - stratification%20thermique

La stratification thermique de l'air est importante pour la compréhension de la dispersion des polluants. Si la température diminue de façon constante avec l'altitude, l'atmosphère est alors dite instable, le polluant se disperse davantage en hauteur. S'il se met en place une couche d'inversion, c'est à dire que la température augmente de nouveau en altitude, l'atmosphère est dite stable. Si le polluant est émis en dessous de cette limite d'inversion, dans la couche limite atmosphérique, le polluant sera bloqué dans sa progression verticale, tandis que s'il est émis au dessus, sa dispersion vers le sol sera bloquée. 5, record 1, French, - stratification%20thermique

La lithosphère est l'enveloppe la plus externe de la Terre qui comprend la croûte et une partie du manteau sous-jacent. On distingue trois lithosphères, thermique, chimique et mécanique. La lithosphère thermique est caractérisée par une forte augmentation de la température avec la profondeur, contrairement au manteau sous-jacent qui est quasiment à une température uniforme. Elle correspond à la couche limite thermique supérieure du manteau en convection. [...] La lithosphère thermique est par définition la couche limite thermique supérieure du domaine convectif [...] 4, record 2, French, - couche%20limite%20thermique

La région se trouvant entre le noyau et le manteau est appelée la «couche D» qui est uniquement conductrice de chaleur; une région conductrice séparée par deux zones convectives est appelée une couche-limite thermique. Dans de telles zones, se développent des hétérogénéités thermiques mais aussi des hétérogénéités dans la structure (la vitesse des ondes élastiques n'augmente pas autant que dans le reste du manteau inférieur). 5, record 2, French, - couche%20limite%20thermique

Boundary Layers. A consequence of any fluid-surface interaction(as is found in convective heat transfer) is the development of a region in the fluid through which the velocity varies from zero at the surface to a finite value... associated with the flow. This region is known as the hydrodynamic, or velocity boundary layer. If there is a difference in the surface and flow temperatures, there will also develop a region in the fluid through which the temperature varies... in the outer flow... This region, called the thermal boundary layer, may be smaller, larger or the same size as that through which the velocity varies. 2, record 4, English, - thermal%20boundary%20layer

Couches limites et dynamiques. Quel que soit le régime d'écoulement, il demeure une sous-couche laminaire (couche limite dynamique) dont l'épaisseur est d'autant plus réduite que le nombre de Reynolds est grand. L'épaisseur de cette couche limite varie en fonction de nombreux paramètres : nature du fluide, température, rugosité de la paroi... L'analogie de Reynolds montre que le gradient thermique est particulièrement important au voisinage de la paroi, c'est à dire dans la sous-couche laminaire. Quel que soit le régime d'écoulement du fluide, on considère que la résistance thermique est entièrement située dans le film laminaire qui joue le rôle d'isolant thermique (couche limite thermique). 2, record 4, French, - couche%20limite%20thermique
