High cirrus clouds are pushed along by the jet stream, sometimes traveling at more than miles-per-hour. When clouds are part of a thunderstorm they usually travel at 30 to 40 mph. Why do clouds form at different heights in the atmosphere?
The characteristics of clouds are dictated by the elements available, including the amount of water vapor, the temperatures at that height, the wind, and the interplay of other air masses.
How is fog formed? There are many different types of fog, but fog is mostly formed when southerly winds bring warm, moist air into a region, possibly ending a cold outbreak. As the warm, moist air flows over much colder soil or snow, dense fog often forms. Warm, moist air is cooled from below as it flows over a colder surface.
Cirrus and cirrocumulus clouds appear at the same altitude , so some people tend to confuse them when they try to identify high clouds. However, what makes them different is that cirrocumulus clouds are formed by cloudlets that form a bigger cloud while cirrus clouds look more fiber-like. However, the best way to differentiate them is to see their color and shape.
The cirrostratus clouds are more translucent and are often layered. As you could see, there is a lot to know about cirrus clouds. Yet, there is a lot more to know about clouds. That way you can keep studying with them and help them understand more things about clouds. Download our app. July 16, 5 min read. What Are Cirrus Clouds? How Do Cirrus Clouds Form? Cirrus Cloud Facts There are many things to know about cirrus clouds.
Cirrus Clouds Species As mentioned before, cirrus clouds are divided into species. The five cirrus clouds species are : Cirrus Castellanus Cirrus castellanus clouds are often called turrets. Cirrus Fibratus Similar to its name, cirrus fibrates clouds look fiber-like. Cirrus Floccus Unlike cirrus fibratus, cirrus floccus looks puffy and bigger than the previous cloud types. Cirrus Spissatus These clouds sometimes lack a specific form. Cirrus Uncinus Cirrus uncinus clouds are very similar to cirrus fibratus clouds.
Cirrus Cloud Supplementary Features Clouds tend to have supplementary features attached to them. They are: Cirrus Fluctus Cirrus fluctus clouds look like waves or curls. Cirrus Mamma These clouds are similar to cirrus spissatus clouds.
These delicate clouds are wispy, with a silky sheen, or look like tufts of hair. In the daytime, they are whiter than any other cloud in the sky. While the Sun is setting or rising, they may take on the colours of the sunset. Cirrus clouds form from the ascent of dry air, making the small quantity of water vapour in the air undergo deposition into ice to change from a gas directly into a solid.
Cirrus is made up completely of ice crystals, which provides their white colour and form in a wide range of shapes and sizes. Cirrus clouds can also form through contrails , the vapour trails left by planes as they fly through a dry upper troposphere.
