Sometimes cumulus clouds are white and there are only a few of them in the sky; other times they can be heavy and gray. They’re usually low-level clouds, only about 1000 meters (3300 feet) above the ground.
When do you see cumulus clouds?
Usually you get cumulus clouds when warm air rises from the ground carrying water vapor with it by evaporation. When the warm wet air rises up and meets some cold air, the water vapor gets colder and condenses into drops of water, making a cloud.
Why does warm air rise?
Which cumulus clouds are rain clouds?
When cumulus clouds are white and puffy, that usually means it’s not going to rain right away. But if they grow into big gray clouds, you can expect rain. Or it might snow if it is cold enough.
