Clouds

Meteorologists, who are scientists who study weather, separate the clouds into four basic groups. Cumulus clouds are formed as the air rises and expands out in all directions, giving them a fluffy “piled” look. Cumulonimbus clouds are sometimes called “thunderheads” because they are so large and dark. Above many, Cirrus clouds are located high in the troposphere, so they are filled with tiny ice crystals. This gives the clouds a feathery appearance while the wind makes them thin and flowing. Having a layered look, Stratus clouds form low in the sky, diligently bringing rain. These different clouds can tell us a lot about what kind of weather is approaching!By Jill
