Pileus (Latin for "skullcap") is a smooth cloud found
attached to either
a mountain top or growing cumulus tower.

The lifted air that produces pileus clouds is typically drier than the
moist air from lower levels often responsible for
cumulus clouds.
There is little tendency
for any significant vertical growth in pileus clouds, which is why
they take on a smoother, horizontal shape.
