Kelvin-Helmholtz cloud (wave-shaped)

Kelvin-Helmholtz clouds are true works of art in the sky. Their spectacular shape, reminiscent of waves about to break, is not accidental: it appears when two layers of air slide over each other at different speeds. This difference in speed creates atmospheric instability that makes the cloud undulate, just like wind sculpts waves on the ocean's surface.

Rare and often short-lived, these clouds generally form in windy weather, at medium altitudes, and disappear as quickly as they appeared. Observing them is therefore a small privilege for the eyes… and a treat for science and weather enthusiasts.

Elegant, dynamic, and scientifically fascinating, Kelvin-Helmholtz clouds prove that physics can be incredibly beautiful. Bring these celestial waves into your collection by adding the Kelvin-Helmholtz sticker: a touch of science, movement, and poetry for your everyday life.
