Record 1 2022-11-30

English

Subject field(s)
  • Atmospheric Physics
CONT

In addition to the vertical distribution of air temperature, there also exists a horizontal distribution of air temperature, due to the differential heating of the incoming solar radiation between the low and high latitudes. Typically, the air temperature decreases poleward in the troposphere.

Key term(s)
  • air temperature horizontal distribution

French

Domaine(s)
  • Physique de l'atmosphère

Spanish

Record 2 2022-11-30

English

Subject field(s)
  • Atmospheric Physics
CONT

The earth's atmosphere is mostly transparent to the incoming solar radiation, and hence the above radiation from the sun is absorbed by the earth surface. The earth's atmosphere in turn absorbs the terrestrial long wave radiation from the earth surface resulting in a situation where the atmosphere is primarily heated from below. This results in a vertical distribution of air temperature, wherein the air temperature decreases with height.

Record 3 2003-10-23

English

Subject field(s)
  • Climatology
  • Geophysics
CONT

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.

CONT

The atmospheric regions of the homosphere can be described by the pattern of the temperature distribution : the troposphere... ;the stratosphere... ;the mesosphere... ;the thermosphere... Vertical profile of the total concentration in the homosphere, air mixing is sufficient to maintain an uniform air composition : 78% N2, 21% O2 and 1% Ar.

French

Domaine(s)
  • Climatologie
  • Géophysique
CONT

On groupe sous le nom de turbulence toute une catégorie de phénomènes assez différents, mais qui se traduisent tous par l'agitation et le brassage de l'air dans une couche d'épaisseur limitée (quelques dizaines ou quelques centaines de mètres).

CONT

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.
