On Friday, November 14, rare Asperitas clouds could be seen in the sky over the capital area. This Latin word, meaning “roughness,” refers to the distinct wavy structures at the bottom of some clouds.

Leading researcher and head of the climate dynamics laboratory at the Moscow Institute of Physics and Technology, Olga Zolina explained in a commentary to AGN “Moscow“The appearance of such clouds, often called “ghosts”, is due to atmospheric instability – it leads to the mixing of horizontal and vertical air flows.
Professor of Physics and Technology at the School of Applied Mathematics and Informatics at the Moscow Institute of Physics and Technology and employee of the Russian Hydrometeorological Center Mikhail Tolstykh said that “evil” clouds can usually be observed in the summer. Their appearance signals atmospheric instability and may be accompanied by thunderstorms.
Previously, there was one in the capital region observe a rare case is mammals. These are pocket-like structures that hang at the lower edges of powerful cumulonimbus clouds, also known as cumulonimbus clouds. Their appearance can cause risks to the aviation industry and extreme weather events can occur.
