0 a type of cumulus (= a tall, rounded, white cloud with a flat base) formed in a very thin layer and often in a regular pattern
A few cirrocumulus clouds were coming up from the east when we started, but we left them behind, and nothing was visible during the night but a thin hazy veil.
Towards afternoon, cirrocumulus and cirrostratus began to appear moving northward.
It is a fairly uncommon phenomenon, most often observed in altocumulus, cirrocumulus, lenticular clouds and cirrus clouds.
Cirrocumulus lenticularis forms when stable air is forced upward; this is usually due to orographic features, but can occur away from mountains as well.
Cirrocumulus clouds never cast self-shadows and are translucent to a certain degree.
Convection at high altitudes can produce another high-based genus called cirrocumulus, a pattern of small cloud tufts that contain droplets of supercooled water.
Cirrocumulus castellanus is an indicator of atmospheric instability at the level of the cloud.
