Crepuscular rays are an optical effect produced when light goes through a dusty atmosphere. They are rays of light that appear to diverge outward from the setting sun, and are visible only when the atmosphere contains a certain amount of dust particles. 7, record 1, English, - crepuscular%20ray

rayons crépusculaires : Bandes d’un bleu foncé qui rayonnent à partir du Soleil et traversent la lueur pourpre pendant le crépuscule. Ce sont les ombres de nuages situés à l’horizon ou derrière l’horizon. 3, record 1, French, - rayon%20cr%C3%A9pusculaire

Si, dans la basse atmosphère, quelque chose, comme une colline ou un nuage, bloque une partie de la lumière solaire, on voit alors apparaître ce qui reste de lumière comme des rayons. Ceux-ci, intensifiés par la diffusion de la lumière dans l'air situé entre l'obstacle et l'observateur semblent diverger directement du soleil. On les appelle rayons crépusculaires ou échelle de Jacob en Angleterre. Ils peuvent apparaître autant au lever qu'au coucher du soleil, lorsque celui-ci est bas à l'horizon ou même sous l'horizon. On peut voir de tels rayons surtout quand l'atmosphère contient assez de particules de poussière ou de brume de sorte que la lumière solaire des régions sans ombre est diffusée directement vers l'observateur. En réalité, ces rayons sont parallèles, mais à cause de l'effet de parallaxe, on dirait qu'ils convergent vers le soleil. Cet effet rappelle les rails d’un chemin de fer qui semblent converger quand on les regarde au loin. La couleur de ces rayons est souvent dans les teintes de rouge ou jaune, tout simplement parce que le bleu a déjà été diffusé par les molécules d’air. 2, record 1, French, - rayon%20cr%C3%A9pusculaire
