Clouions

Clouions are a type of cloud that form at high altitudes, typically above 20,000 feet (6,000 meters). They are composed of ice crystals and are often associated with cold weather conditions. Clouions can take various shapes and sizes, including thin, wispy strands and puffy, cotton-like formations. They are often seen in the winter months and can indicate the presence of a warm front or a low-pressure system.

Clouions are a type of cirrus cloud, which are the highest clouds in the Earth's atmosphere. They are typically thin and transparent, and their ice crystals can create a halo effect around the sun or moon. Clouions can also indicate the approach of a storm, as they often precede the arrival of a warm front or a low-pressure system.

Clouions are an important part of the Earth's weather patterns, as they can help to regulate the temperature and humidity of the atmosphere. They can also play a role in the formation of other types of clouds, such as altostratus and nimbostratus. Despite their delicate appearance, clouions can have a significant impact on the weather and climate of the Earth.
