Cirrocumulus castellanus is a type of cirrocumulus cloud. The name cirrocumulus catellanus is derived from Latin, meaning "of a castle".[1] These clouds appear as round turrets that are rising from either a lowere line or sheet of clouds.[2] Cirrocumulus castellanus is an indicator of atmospheric instability at the level of the cloud.[3] The clouds form when condesnation occurs in the base cloud, causing latent heating to occur. This causes air to rise from the base cloud, and if the air ascends into conditionally unstable air, cirrocumulus castellanus will form.[4]
