Curious, beautiful and, at the same time, terrifying and hypnotic. This is how this UFO cloud that we see in La Vanguardia's Readers' Photos was shown and that was perched in the sky above the beautiful town of Alquezar, in the province of Huesca. And I fall short when describing it, since it appears on the list of the ten best towns in Spain.
Several minutes passed and I couldn't stop looking at it, since in my imagination I saw tiny colorful beings that came out of it in peace to greet us as if it were a mother ship. And so on until it dissipated, becoming soft cloudy threads.
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.
