Types of clouds #4

An altocumulus cloud is a mid-level cloud that is usually about 1 kilometre thick. It comes from the latin word altus, which means high. It is described by many patches and rolls, like many small islands in the sky. If you see altocumulus clouds in the morning and it is really humid that day, then there is a good chance that there will be a thunderstorm later in the day.
