The space agency explains the phenomenon.
NASA decided to highlight on one of its sites a photograph of the island of Madeira, covered by clouds in a phenomenon that the American space agency took advantage of and explain in detail.
The photograph was taken on July 16 by the Moderate Resolution Imaging Spectroradiometer (MODIS), which is on board the Terra satellite. The image serves to explain the strange pattern that covers the island, with NASA indicating that “this cloud trail is an observable part of a wind pattern called ‘von Kármán vortices'”.
The vortexes were made when a fluid flow (of wind) comes into contact with a solid object that, in this case, is our Madeira Island disturbing the air mass and creating the pattern that can be seen in the image.
