Cirrus Clouds : New Study
A new study has found a significant statistical correlation between thunderstorms occurring around the world and the formation of wispy cirrus clouds, which might increase global warming.
- Cirrus Clouds are delicate, feathery clouds that are made mostly of ice crystals.
- They are thin and wispy in appearance, often appearing as delicate, high-altitude filaments or strands.
- Their wispy shape comes from wind currents, which twist and spread the ice crystals into strands.
- They are usually white or have a light grey colour. In the daytime, they are whiter than any other cloud in the sky.
- They are commonly known as “mare’s tails” because they are shaped like the tail of a horse.
- Typically found at heights greater than 20,000 feet (6,000 metres), cirrus clouds are composed of ice crystals that originate from the freezing of supercooled water droplets.
- They generally occur in fair weather and point in the direction of air movement at their elevation.
