A circular red-pink cloud appeared in the sky over the Turkish city of Bursa during sunrise, featuring a large hole in its center. The British newspaper "Daily Mail" reports that this type of formation is known as a "lenticular cloud" – a cloud that forms when the air is stable and winds blow across hills and mountains from the same direction or similar at varying heights through the troposphere. The name "lenticular clouds" is derived from the Latin term "Altocumulus lenticularis," which translates to "lens-like."
These clouds are recognized for their curved, saucer-like appearance and are typically found at altitudes ranging from 6,400 to 16,500 feet. The newspaper quoted the British Meteorological Office stating that "these strange, unnatural clouds sometimes form downwind of hills or mountains." The office added, "These clouds closely resemble the traditional shape of flying saucers in science fiction, and true lenticular clouds are considered one of the most common explanations for sightings of unidentified flying objects worldwide."
"If there is sufficient moisture in the air, the wave's upward motion will cause water vapor to condense, creating the unique appearance of lenticular clouds," according to the British Meteorological Office. Last month, noctilucent clouds – among the rarest clouds in the world – appeared over the San Francisco Bay Area, shortly after a SpaceX rocket launch.
