Mammatus are bulbous formations that are found under other clouds.

While most clouds have flat bottoms, mammatus have round pouches that are caused by sinking air.

This has led to cloud physicists referring to the shape as being caused by negative buoyancy.
Their name is said to be derived from the Latin for breast.

The clouds, which often form in turbulent air, can stretch for hundreds of miles and can be a sign of a gathering storm.

For the clouds to form, there must be a sharp change in temperature.
