Lenticular Cloud Over Mount Fuji: The Stunning UFO-Like Phenomenon

One of nature’s most captivating sights is the lenticular cloud forming over Mount Fuji in Japan.

These rare formations often appear as a perfectly stationary “flying saucer” or UFO hovering directly above the iconic volcano’s summit, creating breathtaking and otherworldly photos that frequently go viral.

Lenticular clouds (scientifically known as altocumulus standing lenticularis) develop when moist air is forced upward by a topographic barrier, such as a mountain.

As the air flows over Mount Fuji, it creates standing atmospheric waves. Water vapor condenses at the wave crests, forming smooth, lens-shaped clouds that remain fixed in position despite strong winds.

Why Mount Fuji is Perfect for Lenticular Clouds

The symmetrical cone shape and isolated position of Mount Fuji make it an ideal obstacle for generating these atmospheric waves.

When winds are strong and perpendicular to the mountain, the conditions are ripe for spectacular lenticular cloud displays, especially at dawn or dusk when lighting enhances their dramatic appearance.

A Warning Sign for Aviators

While beautiful from the ground, these clouds signal significant turbulence and wind shear in the atmosphere. Pilots avoid flying near lenticular clouds because the powerful mountain waves can pose serious hazards to aircraft.

This natural wonder continues to fascinate photographers, hikers, and skywatchers around the world, reminding us of the incredible beauty hidden in atmospheric physics.
