Why do clouds look fluffy?

When warm air rises from the ground, it carries water vapor with it. When the water vapor meets the cold air found high in the sky, the gas condenses to liquid and forms cumulus clouds. While these fluffy-white clouds look like soft pillows of cotton, they are actually composed of small water droplets.


Where are cirrus clouds located?

Typically found at heights greater than 20,000 feet (6,000 meters), cirrus clouds are composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus generally occur in fair weather and point in the direction of air movement at their elevation.

Why are cirrus clouds so thin?

Cirrus are thin, whispy clouds composed of ice crystals that originate from the freezing of supercooled water droplets and exist where temperatures are below -38 degrees Celsius. … The change in wind with height and how quickly these ice crystals actually fall determine the shapes and sizes the fall streaks attain.

What is cirrostratus in Latin?

The name cirrostratus nebulosus is derived from Latin, the adjective nebulosus meaning « full of vapor, foggy, cloudy, dark« . Cirrostratus nebulosus is one of the two most common forms that cirrostratus often takes, with the other being cirrostratus fibratus.

What causes cirrus clouds to form?

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.

Are clouds fluffy?

Why do clouds turn GREY?

As their thickness increases, the bottoms of clouds look darker but still scatter all colors. We perceive this as gray.

Are cirrus clouds ice?

Cirrus clouds are wispy, feathery, and composed entirely of ice crystals. They often are the first sign of an approaching warm front or upper-level jet streak. Unlike cirrus, cirrostratus clouds form more of a widespread, veil-like layer (similar to what stratus clouds do in low levels).

Is a cirrus cloud high or low?
