Uncommon cloud formations, which have traditionally been associated with various UFO sightings, have recently been observed in the northern skies of the UK.
This unique cloud structure received its nickname due to the smooth, symmetrical oval or circular shapes it manifests, which many have likened to the science fiction portrayal of flying saucers.
Additionally, they are sometimes called pancake clouds, as they may appear flat and layered.
However, the formal designation is lenticular clouds, derived from a Latin term meaning “lens-shaped”.
These clouds, which are quite infrequent in the UK, were detected earlier this week over northern regions including Gateshead, Newcastle, Cumbria, and Scotland.
The formation occurs when the atmosphere is stable, and winds traverse hills and mountains from the same or similar directions at varying altitudes through the troposphere—the lowest layer of Earth’s atmosphere, as stated by the Met Office.

According to the Met Office, “When air travels across a mountain range, under particular conditions, it can create a series of significant standing waves in the air downstream, similar to the ripples that form in a river due to an obstruction.”
“If sufficient moisture exists in the air, the wave’s upward movement can lead to water vapor condensing, resulting in the hallmark appearance of lenticular clouds.”

Do the clouds indicate anything?
These UFO-like clouds may not transport anyone skyward, yet they can generate powerful, gusty winds on the ground within a confined area.
Pilots typically steer clear of flying in proximity to them due to the potential for significant turbulence, as noted by the Met Office, whereas adept glider pilots are keen on them since they serve as a visual cue indicating where the air is likely to ascend.
