How do ring clouds form in the Earth's atmosphere and what impact do they have on weather patterns?

Ring clouds, also known as "cirrus clouds," form in the Earth's atmosphere when ice crystals are carried by high-altitude winds. These clouds are thin and wispy in appearance. Ring clouds do not have a direct impact on weather patterns, but their presence can indicate the presence of an approaching weather system. They are often associated with fair weather, but can also signal the arrival of a storm.
