Record 1 2011-07-21

English

Subject field(s)
  • Atmospheric Physics
  • Geophysics
DEF

Two intense electric currents, flowing around the auroral oval from the day side towards the night side and meeting somewhat west of midnight.

OBS

auroral electrojets: when used in the singular (auroral electrojet) it designates one of the two currents flowing around the auroral oval: "one flows eastward along the evening part of the auroral oval and the other flows westward in the morning part".

Key term(s)
  • auroral electro-jets
  • auroral electro jets
  • auroral electrojet
  • auroral electro-jet
  • auroral electro jet

French

Domaine(s)
  • Physique de l'atmosphère
  • Géophysique
CONT

De puissants courants électriques sont également générés et précipités dans l'ionosphère dans les zones aurorales oû sont produits des courants est-ouest intenses appelés «électrojets auroraux». Les perturbations magnétiques observées à hautes latitudes sont déclenchées par les champs magnétiques de ces électrojets.

Key term(s)
  • électrojet auroral

Record 2 2004-09-24

English

Subject field(s)
  • Atmospheric Physics
  • Geophysics
DEF

A current that flows in the ionosphere in the auroral zone.

OBS

auroral electrojet: when used in the plural (auroral electrojets) it generally designates both currents flowing around the auroral oval.

OBS

Auroral electrojets: Narrowly concentrated ionospheric currents; one flows eastward along the evening part of the auroral oval and the other flows westward in the morning part.

OBS

electrojet: Intense sheet of electric current, a few degrees wide in latitude and at an altitude of about 100 km, located near 67°N or S magnetic latitude (auroral electrojet) or near the magnetic equator (equatorial electrojet).

OBS

Electrojet [is] a region of sheet current flowing in the E Region of the ionosphere.

Key term(s)
  • auroral electro-jet
  • auroral electro jet
  • auroral electrojets

French

Domaine(s)
  • Physique de l'atmosphère
  • Géophysique
OBS

Électrojet : Nappe de courant électrique intense, large de quelques degrés de latitude et à environ 100 km d'altitude, située vers 67° de latitude géomagnétique N ou S (électrojet auroral) ou près de l'équateur magnétique (électrojet équatorial).

Spanish

Campo(s) temático(s)

corriente eléctrica a chorro: Lámina de corriente eléctrica muy intensa, con una anchura de unos pocos grados de latitud a una altitud de unos 100 km, situada en la proximidad de los 67° N y S de latitud geomagnética (corriente eléctrica en chorro auroral) y cerca del ecuador magnético (corriente eléctrica en chorro ecuatorial).

Key term(s)
  • corriente auroral de electrones en chorro
