QUE SIGNIFIE ELECTROJET EN ANGLAIS
Electrojet
Un électrojet est un courant électrique qui circule autour de la région E de l'ionosphère terrestre. Il y a deux électrojets: au-dessus de l'équateur magnétique et à proximité des cercles polaires nord et sud. Les électrojets sont des courants de Hall transportés principalement par des électrons à des altitudes de 100 à 150 km. Dans cette région, la fréquence du gyroscope électronique est beaucoup plus grande que la fréquence de collision neutre en électrons. En revanche, les principaux ions de la région E ont des gyrofréquences bien inférieures à la fréquence de collision neutre ionique. Kristian Birkeland a été le premier à suggérer que les courants électriques polaires sont connectés à un système de filaments qui s'écoulent le long des lignes de champs géomagnétiques dans et loin de la région polaire.
définition de electrojet dans le dictionnaire anglais
La définition de l'électrojet dans le dictionnaire est une bande étroite d'ions se déplaçant rapidement dans l'ionosphère, sous l'influence du champ magnétique terrestre, provoquant des affichages auroraux.
