    What are altocumulus undulatus clouds?
    Altocumulus undulatus clouds appear as mid-altitude cloud heaps arranged in parallel rows. Stratocumulus undulatus clouds are puffy, undulating clouds low in altitude. Undulatus clouds are a bit more difficult to pick out in stratiform clouds. Cirrostratus undulatus clouds can be described as thin, high-altitude sheets with subtle wave patterns.

    The name is derived from unda, the Latin word for a wave. Sometimes, they are in the form of a continuous layer with an undulating surface. Other times, they are like lines of cloud with gaps in between, as in this fine Altocumulus undulatus, spotted over Fife in Scotland.
