* Stratus: These are flat, gray clouds that cover the sky like a blanket. They often produce drizzle or light snow.
* Cumulus: These are fluffy, white clouds with flat bases. They are often called "fair weather clouds" but can develop into towering cumulonimbus clouds that produce thunderstorms.
* Stratocumulus: These are low, lumpy clouds arranged in rows or patches. They often produce light rain or snow.
* Nimbostratus: These are dark, gray clouds that can produce heavy rain or snow. They often cover the entire sky and can be associated with thunderstorms.
* Cumulonimbus: These are towering clouds that are associated with thunderstorms. They can reach high into the atmosphere and produce heavy rain, hail, lightning, and strong winds.
These clouds are typically found below 2,000 meters (6,500 feet) in altitude. They are made up of water droplets, but they can also contain ice crystals if the temperature is cold enough.
