This cloud that we were able to see in Llívia, in Baixa Cerdanya, around 1:20 p.m. really looked like a UFO, as can be seen in these photographs in La Vanguardia's Readers' Photos.
The so-called wind clouds usually have shapes that attract our attention. The most characteristic are the lenticular ones, so called because they look like a lentil, but they also take the shape of a flying saucer or UFO, as well as converging lenses.
They are stationary and form mainly at high altitudes in mountainous areas and isolated from other clouds. In this case we can see a solitary UFO cloud.
Among mountaineers these clouds are considered a harbinger of a storm. As a curiosity, glider pilots continually look for this type of clouds because the atmospheric system that forms them involves large vertical movements of air. And the precise location of the rising air is very easy to predict by looking at the orientation of the cloud.
Llívia, at 1223 meters of altitude, is in the Pyrenees, in the Cerdanya valley. It is located at the foot of Turó del Castell and stretches across the Fontanelles plain.
