Il n’a pas forcément été visible partout aujourd’hui, du coup le #QuizzEnergieClimat vous amène un peu de soleil ! ☀️😊

Question n°84 :
L’activité solaire varie de façon cyclique. Quelle est la durée (période) de ces cycles ?

Réponse question n°84 :
La durée des cycles solaires est de 11 ans.
Notez l’échelle verticale sur le graphique, la variation est de l’ordre de 1 W/m2
