The Met Office said: "Kelvin Helmholtz clouds, or fluctus clouds, are quite rare. "These clouds are more likely to be seen on windy days when there is a difference in density of the air.
Kelvin-Helmholtz instabilities are visible in the atmospheres of planets and moons, such as in cloud formations on Earth or the Red Spot on Jupiter, and the atmospheres of the Sun and other stars. [1] Spatially developing 2D Kelvin-Helmholtz instability at low Reynolds number. Small perturbations, imposed at the inlet on the tangential velocity ...
A curious cloud seen over Smith Mountain looks more like something out of a fairytale than it does real life — and the science behind it is fascinating. What are Kelvin-Helmholtz clouds?
Lens-shaped middle cloud. Includes informal variant altocumulus Kelvin–Helmholtz cloud, lenticular spiral indicative of severe turbulence. Altocumulus volutus (V-27) Elongated, tube shaped, horizontal stratocumuliform cloud. Altocumulus castellanus (V-28) Turreted layer cloud. Altocumulus floccus (V-29) Tufted stratocumuliform clouds with ...
This is an image, captured in San Francisco, which shows the "ocean wave" like pattern associated with the Kelvin–Helmholtz instability forming in clouds. The Kelvin–Helmholtz instability (KHI) is an application of hydrodynamic stability that can be seen in nature. It occurs when there are two fluids flowing at different velocities.

Mammatus clouds filled the sky over Bucks County on Sunday night, June 30, 2024, giving a treat of orange and pink fluffy clouds and filling social media with the spectacular sky.
