Record 1 2012-03-07

English

Subject field(s)
  • Air Pollution
  • Atmospheric Physics
  • Chimneys (Building Elements)
DEF

An atmospheric phenomenon whereby a smoke plume, formerly retained by an inversion layer near its emission level, is rapidly pushed down to ground level by turbulence when the inversion breaks up, causing high concentrations of pollutants at ground level.

French

Domaine(s)
  • Pollution de l'air
  • Physique de l'atmosphère
  • Cheminées (Éléments du bâtiment)
DEF

Processus par lequel la pollution accumulée sous une couche stable en altitude est ramenée au sol par mélange convectif.

CONT

Inversion de température en altitude. Les polluants s’accumulent au niveau où règne l'inversion de température. Selon que l'inversion se situe dans les couches inférieures ou supérieures au panache de fumée, celui-ci est tourmenté vers le haut(«lofting») ou vers le bas(«enfumage»).

Spanish

Campo(s) temático(s)
  • Contaminación del aire
  • Física de la atmósfera
  • Chimeneas (Elementos de edificios)
DEF

Proceso por el cual la contaminación acumulada debajo de un estrato estable es transportada hasta el suelo por la agitación convectiva.

Record 3 2002-07-16

English

Subject field(s)
  • Atmospheric Physics
  • Brush, Prairie and Forest Fires
DEF

Smoke at a high atmospheric level in the (relative) absence of smoke at lower levels.

CONT

Smoke Aloft -- Until recent decades, the impact of the lifted portion of smoke was ignored because it seemed to "just go away." These impacts are generally not realized until the mechanisms of dispersal bring the dispersed smoke back to ground level. Because the smoke has already dispersed over a broad area, the intensity of ground-level exposure is minimal. The duration of exposure may include the better part of a day, however, and the area of exposure may be large.

French

Domaine(s)
  • Physique de l'atmosphère
  • Incendies de végétation
DEF

Fumée établie à un niveau élevé dans l’atmosphère libre en l’absence (relative) de fumée aux niveaux inférieurs.

Record 4 2002-04-18

English

Subject field(s)
  • Atmospheric Physics
DEF

Top of a ... smoke ... layer which is confined in a low-level temperature inversion and which has the appearance of a horizon when viewed from above against the sky.

French

Domaine(s)
  • Physique de l'atmosphère
DEF

Sommet d’une couche de [...] fumée [...] confinée par une inversion de température à basse altitude et qui a l'aspect d’un horizon lorsqu'elle est vue d’en haut sur le fond du ciel.

Spanish

Campo(s) temático(s)
  • Física de la atmósfera
DEF

Parte superior de una capa de [...] humo [...] limitada por una inversión de temperatura a baja altura y que se asemeja al horizonte cuando se mira desde arriba contra el fondo del cielo.
