UP SLOPE WIND [4 records]

Record 1 2017-11-23

English

Subject field(s)
  • Skydiving, Paragliding and Hang Gliding
CONT

Paragliders have no rigid structure and are kept in shape by the internal pressure of air, with the pilot suspended by lines beneath. The pilot is clipped into a harness and oriented in a sitting position for maximum comfort. After laying out the wing and lines, launching is simply a matter of moving down the slope a few steps to tension the lines and allow the wind to inflate the wing and raise it above you. A short run forward to pick up airspeed and you’re airborne!

CONT

Paraglider pilots launch from gentle hillsides with their gliders already opened for flight; if the glider isn’t flying properly, the launch can be aborted before leaving the ground. Paragliding launches are not as "committing"; if you want to stop your launch, you just stop running and the canopy floats down behind you. The pilot runs down a gentle slope and glides away from the mountain.

CONT

The take-off, contrary to popular belief, does not involve a leap off a cliff, all you have to do is run a few steps to be airborne.

Key term(s)
  • take off
  • takeoff

French

Domaine(s)
  • Parachutisme, parapente et deltaplane
CONT

Le décollage s'effectue en général dans une pente. Le parapentiste place son aile à terre, bien étalée (en forme de corolle) et face à la pente. Il s'installe dans sa sellette en veillant bien à respecter les vérifications d'usage (points d'accrochages de la sellette, casque, radio et pas de nœuds dans les suspentes). Il faut qu'il y ait une légère brise qui remonte la pente face à lui pour lui faciliter le décollage et que les conditions météorologiques soient adaptées.

CONT

Le décollage dépend aussi des conditions aérologiques et de la structure du relief choisi. On ne saute pas, on ne se jette pas, on décolle et un décollage est rapide lorsqu'il y a un peu de vent de face, et nécessite un peu plus de temps et de course d'élan lorsque le vent est faible ou nul.

Record 3 2003-09-26

English

Subject field(s)
  • Atmospheric Physics
DEF

A gentle wind blowing up a valley or mountain slope in the absence of cyclonic or anticyclonic winds, caused by the warming of the mountainside and valley floor by the sun.

CONT

A valley breeze develops during the day as the sun heats the land surface and air at the valley bottom and sides ... As the air heats it becomes less dense and buoyant and begins to flow gently up the valley sides. Vertical ascent of the air rising along the sides of the mountain is usually limited by the presence of a temperature inversion layer. When the ascending air currents encounter the inversion they are forced to move horizontally and then back down to the valley floor. This creates a self-contained circulation system. If conditions are right, the rising air can condense and form into cumuliform clouds.

French

Domaine(s)
  • Physique de l'atmosphère
DEF

Vent anabatique soufflant le jour le long des pentes, des vallées vers les montagnes.

CONT

Brise de pente et brise de vallée. De jour, le réchauffement de l'air le long des pentes produit un flux ascendant vers les crêtes, d'où un courant général vers le haut de la vallée, c'est la brise d'aval. De nuit, au contraire, l'air se refroidit au contact du sol et a tendance à descendre le long des pentes vers le fond de la vallée où s'instaure un courant général vers le bas de la vallée, c'est la brise d'amont.

Spanish

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

Viento anabático que sopla por las laderas hacia arriba durante el día.

Record 4 2003-06-09

English

Subject field(s)
  • Atmospheric Physics
DEF

A diurnal thermally driven flow directed up a mountain slope, and usually occurring during daytime; part of the slope wind system.

OBS

upslope winds : anabatic wind, foehn wind, etc.

Key term(s)
  • up-slope wind
  • up slope wind

French

Domaine(s)
  • Physique de l'atmosphère
CONT

Le vent montant de la vallée ou descendant de la montagne, met [...] à l'épreuve plus d'un joueur.

CONT

[...] on distingue plusieurs sortes de vents : vent de mer (sur le littoral), vent de terre, vent ascendant, vent descendant et foehn.
