Weird Clouds

Weird Clouds

Cloud enthusiast, Neil Stevenson, recently sent us this video of ‘weird’ clouds he had filmed above Keswick in the Lake District, UK.

Society founder, Gavin Pretor-Pinney, told us that he’s always called them ‘eyebrow clouds’ as they do rather have that appearance. He says they are caused by turbulence as the wind blows over raised ground such as a mountain peak, which fits with the Lake District location. As these clouds have very small and very regularly sized droplets they do often produce iridescent colours which result from the sunlight being diffracted around the tiny droplets.
