Earth’s Newest Cloud is Terrifying And Apocalyptic – Video


On World Meteorological Day — nine years after the classification was first submitted of these cloud formation— the World Meteorological Organization finally recognized Pretor-Pinney’s clouds in the updated version of the International Cloud Atlas, though the name has been tweaked to “asperitas.” They’re the first new addition to the Atlas in over half a century.

Pretor-Pinney described the formations as “localized waves in the cloud base, either smooth or dappled with smaller features, seldom descending into acute points as if viewing a roughened sea surface from below. Varying levels of illumination and depth of cloud can point to dramatic visual effects.” Asperitas clouds tend to be low-lying and are generate by weather fronts that create moving waves in the atmosphere.
