This bizarre cloud formation has formed rings round the top of a mountain. The lenticular cloud sits atop the towering Mount Fuji, in Japan, during an otherwise blue skied day.
The lens-shaped clouds are formed at high altitudes, when a moist air flow encounters obstructions - such as mountains or buildings - which disrupt the air flow and create standing waves in the atmosphere. These waves form on the downwind side and as the moisture in the air condenses, it forms these odd-shaped clouds.
Photographer Akihiro Shibata spotted the clouds circling the top of Mount Fuji, which is the highest mountain in Japan at 3,776m, while at Yamanashi Prefecture Lake Tanuki, in Fujinomiya, Japan. SEE OUR COPY FOR DETAILS.
