Asperitas (cloud) - Wikipedia Asperitas (formerly known as Undulatus asperatus) is a cloud formation first popularized and proposed as a type of cloud in 2009 by Gavin Pretor-Pinney of the Cloud Appreciation Society Added to the International Cloud Atlas as a supplementary feature in March 2017, it is the first cloud formation added since cirrus intortus in 1951 [ 2 ]

The Undulations of Wave Clouds - NASA Earth Observatory Wave clouds (sometimes called undulatus or billow clouds) like these are the product of atmospheric gravity waves They typically form when something forces a mass of air upward The air cools as it rises and, if there is enough moisture in the air, the water condenses and forms clouds
Undulatus - International Cloud Atlas Clouds in patches, sheets or layers, showing undulations These undulations may be observed in fairly uniform cloud layers or in clouds composed of elements, separate or merged Sometimes a double system of undulations is in evidence This term applies mainly to Cirrocumulus, Cirrostratus, Altocumulus, Altostratus, Stratocumulus and Stratus
undulatus - Glossary of Meteorology A cloud variety composed of merged or separate elements that are elongated and parallel, either suggestive of ocean waves or arranged in ranks and files Sometimes two distinct wave systems are apparent (biundulatus)
Undulatus Asperatus: An Epic And Rare Cloud Formation Undulatus asperatus (or alternately, asperatus) is a cloud formation, proposed in 2009 as a separate cloud classification by the founder of the Cloud Appreciation Society If successful it will be the first cloud formation added since cirrus intortus in 1951 to the International Cloud Atlas of the W
