TURBOSPHERE [3 records]

Record 1 2011-06-07

English

Subject field(s)
  • Atmospheric Physics
  • Geophysics
  • The Earth (Astronomy)
DEF

A region of a planetary atmosphere in which mixing occurs predominantly through turbulence.

CONT

Turbosphere [is] that part of the troposphere where the mixing of the atmosphere is achieved more by convection than by diffusion. Its upper limit is the turbopause, an ill-defined layer about 100 km above the earth's surface.

CONT

The turbosphere, 0 to 100 km, is the region where convection effectively mixes atmospheric constituents. ... The homosphere, 0 to 85 km, has the same vertical extent as the turbosphere and the combination of troposphere, stratosphere, and mesosphere.

OBS

Based on a dynamical process distribution, the atmosphere can be divided into: turbosphere, diffusosphere and exosphere.

OBS

"Turbosphere" is a subdivision of the atmosphere based on its mixing process whereas the "homosphere" is a subdivision of the atmosphere based on its chemical composition.

DEF

Subdivision de l'atmosphère basée sur son processus de mélange.

OBS

L'homosphère est une subdivision de l'atmosphère basée sur sa composition chimique.

OBS

Le «Dictionnaire de termes nouveaux des sciences et des techniques» définit la «turbosphère» comme étant une «Zone de transition d'une vingtaine de kilomètres d'épaisseur entre la zone d'atmosphère en équilibre de mélange (homosphère) et la zone d'atmosphère en équilibre de diffusion (hétérosphère).»

Record 2 2004-12-06

English

Subject field(s)
  • Atmospheric Physics
  • Geophysics
  • The Earth (Astronomy)
DEF

Atmospheric region lying between the Earth's surface and a height of 80 km, in which the composition of the atmosphere is almost constant apart from small variations in its minor constituents (CO2, O3 and H2O).

CONT

Homosphere [is] the lower of two portions of the atmosphere as distinguished by the general homogeneity of their composition (the other portion is the heterosphere); it extends from the surface to an altitude of 80 to 100 kilometers above the earth, closely coinciding with the neutrosphere, and is characterized by uniformity of composition.

CONT

... above the homosphere (sometimes called the turbosphere) is the heterosphere.

OBS

Most authors use the term "turbosphere" in the sense of "homosphere"; thus they may be considered synonyms. However, if "turbosphere" is considered strictly based upon the atmospheric division, they are not synonnyms. The turbosphere pertains to the dynamical process distribution: turbosphere, diffusosphere and exosphere and the hemosphere to the composition distribution: homosphere and heterosphere.

OBS

Based on atmospheric characteristics (temperature, dynamical process, particle distribution, chemical composition, ionization, etc.), the atmosphere can be divided into different layers.

French

Domaine(s)

DEF

Région de l'atmosphère s'étendant de la surface terrestre à une altitude de 80 km, dans laquelle la composition atmosphérique est presque constante, sauf de petites variations des constituants mineurs (CO2, O3 et H2O).

OBS

L'homosphère comprend la troposphère, la stratosphère, la mésosphère et la thermosphère. Les principaux constituants (oxygène et hydrogène) y sont en proportions pratiquement constantes.

OBS

Homosphère, hétérosphère et mésosphère : divisions de l'atmosphère selon sa composition. Troposphère, stratosphère, mésosphère et thermosphère : divisions de l'atmosphère selon la température.

OBS

Cette zone s'étend sur une centaine de kilomètres (cinquante pour certains auteurs) dans l'atmosphère à partir de la surface terrestre.

DEF

Región de la atmósfera que se extiende entre la superficie de la Tierra y una altitud de 80 km, en la que la composición de la atmósfera es casi constante, si se exceptúan pequeñas variaciones en los componentes minoritarios (CO2, O3 y H2O).

Record 3 2002-02-13

English

Subject field(s)
  • Atmospheric Physics
  • Geophysics
  • The Sun (Astronomy)
DEF

The [solar] atmospheric region characterized by turbulence.

CONT

The concept of the turbosphere around the Sun was formulated: it is a region in the solar atmosphere where chaotic turbulent velocities dominate over the regular radial expansion of the plasma. The turbosphere is delimited by the nonstationary and highly structured surface - turbopause - in the solar-wind formation region.
