What are Clouds?
Cirrus clouds are located very high in the troposphere (about 7 km). They look curly and wispy, hence the name cirrus, which means "curl." These clouds are usually made of ice crystals, not water droplets.
Cumulus clouds are low level clouds (about 2 km). The are white and puffy clouds that look like balls. The bottom of cumulus clouds are usually flat, while the top is rounded. These clouds usually mean the weather will be nice, and are sometimes called "fair-weather clouds."
Stratus clouds are the lowest lying clouds (between 0-2 km). They usually cover the entire sky like a blanket and usually resemble fog that does not touch the ground. Stratus clouds usually bring light mist and drizzle, but do not cause storms even though they look dark.
Other Types of Clouds
Cirro- Clouds with the cirro- prefix are usually high in the sky with cirrus clouds.
Alto - Alto means middle, so clouds with this prefix are usually located in the mid level.
Strato- Clouds with the strato prefix mean that it forms in the low level.
Nimbus- Clouds with the nimbus prefix (or suffix) usually cause heavy rain and storms.
This type of cloud starts low and goes very,very high. They begin as cumulus clouds in the lower troposphere, and stacks up with other clouds. The cumulonimbus usually causes heavy storms and sometimes even tornadoes. It is shaped like a very big anvil.
