Pasquill' s stability classification scheme was developed to describe dispersion conditions using routinely-available, surfaced-based measurements of wind speed, cloud cover and insolation, and more practically to specify the diffusion parameters [sigma] y and [sigma] z(standard deviations of horizontal and vertical pollutant spread) used in the Gaussian plume model. 1, record 1, English, - Pasquill%27s%20stability%20classification%20scheme

Assuming that a pollutant is being emitted into the environment, how far and fast does it travel, and what is its fate over time? The Gaussian plume model is a(relatively) simple mathematical model that is typically applied to point source emitters, such as coal-burning electricity-producing plants. … One of the key assumptions of this model is that over short periods of time(such as a few hours), steady state conditions exist with regard to air pollutant emissions and meteorological changes. 3, record 2, English, - Gaussian%20plume%20model

Lorsque l'effet de réflexion sur le sol intervient, l'hypothèse d'une source image fictive implique qu'il n'y a pas d'absorption à la surface du sol et que la réflexion du panache est parfaite. De même cette formule ne tient pas compte des réactions chimiques possibles dans l'atmosphère. En outre, comme elle traduit une répartition Gaussienne [sic] des concentrations sur les axes transversaux, cette dernière ne devient significative que pour des temps d'intégration suffisants, compris entre 10 et 20 minutes selon la structure de la turbulence; mais il est évident que seule une valeur intégrée est biologiquement utilisable et que la connaissance de pointes extrêmes de concentrations ne présenterait pas en principe d'intérêt. Toutefois, avec l'accroissement des puissances d'émission on observe parfois, en atmosphère neutre surmontée d'une inversion, des arrivées de panache au sol même, à proche distance de la cheminée, pendant des durées non négligeables, et d'autant plus dangereuses que les puissances d'émission sont alors considérables. 1, record 3, French, - r%C3%A9partition%20gaussienne%20des%20concentrations
