For a few days now, lenticular clouds have been observed with the wind and, at dawn or dusk, they remain in attractive reddish colors. It is a beautiful ephemeral moment that we can relive in La Vanguardia’s Readers’ Photos.

This lower lentil-shaped cloud appears to hang from the larger upper one, as if it were a lamp. I captured the image at dawn in Les Masies de Voltregà, Osona region.

The lenticular cloud is shaped like a lentil, as its name indicates, or like a saucer or converging lens. They are stationary and form at high altitudes in mountainous areas and isolated from other clouds.

Among mountaineers these clouds are considered a harbinger of a storm, although in this case, if it rains, it seems that it would be out to sea.

With these clouds you will like: on the one hand, glider pilots continually look for this type of clouds because the atmospheric system that forms them involves large vertical movements of air (the world record for distance gliding flight: 3000 km, and altitude: 14,938 m, were obtained with this type of clouds).

But on the other hand, airline pilots avoid them due to the turbulence created in the rotor systems.
