Record 1 2023-09-22

English

Subject field(s)
  • Atmospheric Physics
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

... the rotating, localized lowering of the cloud base beneath the rain-free portion of a thunderstorm that often precedes tornado development ...

CONT

Wall clouds can range from a fraction of a mile up to nearly five miles in diameter, and normally are found on the south or southwest (inflow) side of the thunderstorm. Even though this cloud is lowering, it remains attached to the rain free cloud base of the thunderstorm. It is usually located south or southwest of the visible precipitation area, and marks the strongest updraft in the thunderstorm. The wall cloud develops as the strong updraft draws in surface moisture from several miles away.

OBS

"Wall cloud" also is used occasionally in tropical meteorology to describe the inner cloud wall surrounding the eye of a tropical cyclone, but the proper term for this feature is "eyewall. "

French

Domaine(s)
  • Physique de l'atmosphère
  • Phénomènes météorologiques, climatiques et atmosphériques
CONT

Le précurseur typique de la tornade est le mur de nuages. C'est une partie de la base du nuage qui semble s'abaisser vers le sol. On le trouve normalement sur le flanc arrière droit de l'orage. Autrement dit, si l'orage arrive de l'ouest, il faut regarder vers sa partie sud-ouest. Le mur de nuages se forme dans la zone sans précipitations et montre généralement un mouvement de rotation, sous la base du nuage.

Key term(s)
  • nuage mur

DEF

The ring of thunderstorms that surrounds a storm’s eye.

OBS

The heaviest rain, strongest winds and worst turbulence are found in the eyewall.

Record 3 2012-12-20

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
DEF

The distance from the center of a tropical cyclone to the location of the cyclone’s maximum winds.

CONT

In well-developed hurricanes, the radius of maximum winds is generally found at the inner edge of the eyewall.

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
DEF

Record 5 2012-11-21

English

Subject field(s)
  • Atmospheric Physics
  • Atmospheric, Climatic and Meteorological Phenomena
CONT

Some of the outer rainbands may strengthen and organize into a ring of thunderstorms-an outer eyewall-that slowly moves inward and robs the inner eyewall of its needed moisture and angular momentum.

Key term(s)
  • outer eye-wall
  • external eye-wall

French

Domaine(s)
  • Physique de l'atmosphère
  • Phénomènes météorologiques, climatiques et atmosphériques
CONT

Quand l'œil intérieur se forme, la convection qui entoure le mur de l'œil peut s'organiser en anneaux distincts. En fin de compte, l'œil intérieur commence à sentir les effets de la subsidence qui résulte du mur de l'œil externe, et le mur de l'œil intérieur s'affaiblit, pour être remplacé par le mur de l'œil externe.

PHR

Intensification du mur de l'œil externe.

Record 7 2012-10-31

English

Subject field(s)
  • Atmospheric Physics
CONT

The concentric eyewall is often observed in intense hurricanes. The small inner eyewall could be replaced by an outer one. Such eyewall replacement may result in a rapid change in intensity. It is still not clear how the concentric eyewall forms and how it replaces the inner eyewall.

Key term(s)
  • concentric eye wall

French

Domaine(s)
  • Physique de l'atmosphère
CONT

Quelques-uns des cyclones les plus intenses exhibent deux, voire même plusieurs murs de l'œil concentriques [...] Quand l'œil intérieur se forme, la convection qui entoure le mur de l'œil peut s'organiser en anneaux distincts.
