Here are some specific types of low-level clouds:

* Stratus: These are flat, gray clouds that often cover the entire sky. They can produce light drizzle or mist.

* Cumulus: These are fluffy, white clouds that look like cotton balls. They often form on sunny days and are usually harmless.

* Stratocumulus: These are gray or white, patchy clouds that are often arranged in rows or patches. They can produce light rain or snow.

* Nimbostratus: These are dark gray, rain-producing clouds that can cover the entire sky. They are associated with prolonged periods of rain or snow.
