The invasion of lenticular clouds that occurred yesterday at dusk in the sky of the Osona region was a harbinger of today's strong winds. In this series of photographs captured in Torelló for La Vanguardia Readers' Photos we can enjoy this beautiful spectacle in the sky.
Lenticular clouds are called that because they are shaped like a lentil, as their name indicates, or there are also those who see them as a saucer or converging lens.
They are stationary and form mainly at high altitudes in mountainous areas and isolated from other clouds. Among mountaineers these clouds are considered a harbinger of a storm. Or, at the very least, a change in weather, which, in this case, has mainly brought wind. Because, if it rains, nothing, the drought persists in Catalonia.
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 lenticular clouds because of the turbulence created in the rotor systems.
