Summary
editDescriptionStratocumulus Undulatus Asperitas in Allier (FRANCE) on May, 6th 2015.jpg |
Français : Dans la matinée du 6 mai 2015, vers 7H35, des nuages aux allures mystérieuses caractérisées par des ondulations fascinantes déferlent dans le ciel de l'Allier. Ces formations nuageuses nommées "Asperitas" paraissent menaçantes, mais apportent rarement des précipitations. Ce phénomène rarissime se produit surtout dans les contrées anglo-saxonnes (États-Unis, Nouvelle-Zélande, Royaume-Unis) mais aussi en France. Les conditions de formation de ce ce type de nuage demeurent pour le moment inconnues. Est-ce un nuage particulier ou non ? Cette question divise les scientifiques de l' Organisation météorologique mondiale. Certains pensent que ce type de nuage rarissime (observé pour la première fois dans les années 50) devrait être intégré dans l' Atlas International des Nuages. |
