Record 1 2004-03-19

English

Subject field(s)
  • Atmospheric Physics
DEF

The rate of change of pressure with distance.

OBS

pressure gradient; barometric gradient. Mathematically, [it is] a vector, perpendicular to an isobaric line or surface, directed toward low pressure and with a magnitude equal to the rate of change of the pressure with distance. It is equal to -Vp, p being the pressure, or to -[delta]p/[delta]n, n being the distance along the normal directed towards low pressure.

OBS

pressure gradient: the term is sometimes loosely used to denote simply the magnitude of the gradient of the pressure field.

OBS

pressure gradient: term standardized by ISO and officially approved by the International Civil Aviation Organization (ICAO).

French

Domaine(s)
  • Physique de l'atmosphère
DEF

Taux de variation de la pression avec la distance.

OBS

Mathématiquement, [le gradient de pression est un] vecteur perpendiculaire à l'isobare ou à la surface isobare dirigé vers les basses pressions et dont l'intensité est égale au taux de variation de la pression en fonction de la distance.

OBS

gradient de pression : terme normalisé par l'ISO; uniformisé par l'Organisation de l'aviation civile internationale (OACI).

Spanish

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

Tasa de variación de la presión con la distancia.

OBS

Matemáticamente, vector perpendicular a la isobara o a la superficie isobárica dirigido hacia las bajas presiones y cuya magnitud es igual a la tasa de variación de la presión en función de la distancia.

OBS

gradiente de presión; gradiente barométrico: términos aceptados oficialmente por la Organización de Aviación Civil Internacional (OACI).
