These frightening clouds have just been categorized into the International Cloud Map

As if you were underwater and looked at the surface of a screaming ocean.

In the winter of 1803, a British pharmacist named Luke Howard published an article titled "On the Modification of Clouds", in which he made a classification of four main types of clouds including: high clouds and clouds. medium, low clouds, and vertical clouds . In the next century, these terms were further developed and became popular at the end of TK19, which was like a tool in the hope of encoding the most unusual element of nature.

Classify some main clouds.

But all of this has been replaced by a huge International Cloud Map , published in 1896, which quickly became the global standard for cloud classification. Cloud map is divided into four levels of importance level reduction: categories, forms, diversity, and finally the additional features of the cloud.

But 10 years ago, Gavin Pretor-Pinney, a graphic designer decided to create new terms for clouds because of their special shapes. Even in 2004, he founded a Cloud Appreciation Society, a very active online organization with over 56,000 followers via Facebook and thousands of members in nearly 100 countries. family around the world.

Participants are free to post as well as enjoy photos of clouds with the shape of seahorses, ghosts, cyclists, dinosaurs . But after the website is not operating long, Pretor-Pinney received a few photos that did not overlap with any existing cloud classification. A picture taken from the 12th floor in a building in Cedar Rapids, Iowa, looks like the beginning of the apocalypse - a violent flicker in the sky of the city.

The image immediately caused confusion and confusion for followers. Pretor-Pinney described the cloud as the shape of a wave, as if you were underwater and looked at the surface of a screaming ocean. And every six months, Pretor-Pinney received a similar picture in his mailbox. At the same time, he began to wonder if this was a completely new kind of cloud - the first addition to the International Cloud Map for half a century?

Fortunately, the World Meteorological Organization is currently in the process of preparing a new edition of the International Cloud Map. Pretor-Pinney went to the British Royal Meteorological Association and was asked to have scientific arguments for creating a new kind of cloud. So he went to Reading University, where a graduate student accepted to write about this new type of cloud in his thesis.

On this year's meteorological day, the World Meteorological Organization finally recognized the Pretor-Pinney clouds in the updated version of the International Cloud Map, although its name was refined to "asperitas" instead of "undulatus asperatus" as originally. This is the first new addition to the cloud map for more than half a century.

Accurate identification and observation of clouds can help meteorologists adjust weather forecasts, better understand regional ecology and even predict larger changes in global climate. The change in classification can have a significant impact on what is measured and forecasted in the future.

Although these clouds look very cruel, it's good to have a campaign with a large pool of resources so they can be recognized by the scientific community.

Occupying the threshold of beauty of newly classified clouds.
