Unusual Clouds
In nature, there are clouds that closely resemble ocean waves; they are called "Kelvin-Helmholtz clouds."
One cannot fail to mention the beautiful Glory clouds.
These clouds form in several clusters and can be several kilometers long. To this day, scientists are unable to explain the origin of this type of cloud.
In addition to wave-like and roll-shaped clouds, there are lenticular or lens-shaped clouds named after Jacques Cousteau.
Perhaps the most unusual and interesting clouds are the Asperatus clouds.
Asperatus clouds are so rare that they were only classified in 2009.
Mother-of-pearl clouds are neighbors of the northern lights: they are most often seen in polar regions, such as in Iceland, Oslo, or the Swedish Kiruna.
Sky holes are large openings in the middle of clouds. They form when ice crystals in the clouds begin to melt.

Teardrop-shaped clouds. Such clouds form beneath regular clouds. This rare phenomenon occurs due to the mixing of air and clouds with different humidity, where heavier clouds hang below lighter ones.
Mushroom-shaped clouds. They also form over areas with elevated temperatures, such as over forest fires, for example.
Fire rainbow or circumhorizontal arc. Despite the name, a fire rainbow has nothing to do with fire or rainbows. This optical phenomenon occurs due to the refraction of light in tiny ice crystals that make up cirrus clouds. As a result, the cloud entirely transforms into a bright rainbow against the blue sky.
