Add more PATO qualities once they have been added to PATO. When present in aggregates, individual cirrocumulus clouds are merged or separate, and regularly arranged in a thin patch, sheet or layer. Most of the small structural elements have an apparent width of less than one degree. Strongly supercooled water droplets may occur but are usually rapidly replaced by ice crystals. When well-illuminated by sunlight (excluding during sunrise and sunset) cirrocumulus clouds appear white. Absence of any precipitation. envoCloudAtlas water-based cloud high atmospheric level
