Cirrocumulus lacunosus is a type of cirrocumulus cloud. The name cirrocumulus lacunosus is derived from Latin, meaning "full of hollows". Cirrocumulus lacunosus is a relatively rare cloud form that occurs as a layer of cloud with circular holes in it. Formation is commonly attributed to a cool layer mixing with a warmer, higher layer of the atmosphere. These holes normally have frayed edges, and they are often arranged in a manner that resembles a net or a honeycomb.
