Completely different clouds that will happen throughout a extreme thunderstorm
Uncommon, swirling cloud formations had been not too long ago noticed spinning close to the Canary Islands within the Atlantic Ocean off the coast of northwestern Africa, however though they resemble hurricanes, these clouds don’t have the facility related to one of the vital damaging forces of nature on Earth.
The swirling clouds are referred to as “von Karman vortices.” They’re named after Theodore von Karman, a co-founder of NASA’s Jet Propulsion Laboratory and one of many first scientists to explain the bizarre atmospheric phenomenon, in keeping with NOAA’s Nationwide Environmental Satellite tv for pc Knowledge and Info Service (NESDIS).
NESDIS says the clouds happen when the prevailing wind is diverted by elevated land options akin to islands, mountains or volcanoes.
In a tweet posted by the Nationwide Hurricane Heart’s Tropical Evaluation and Forecast Department, a collection of swirling von Karman vortices may be seen in a satellite tv for pc loop spinning south of the Canary Islands. They had been attributable to the air flowing to the southwest across the tall mountains related to the island chain.
AMERICA’S FAVORITE PUNCTUATION MARK IS ALSO A TYPE OF CLOUD
The elevated land options, such because the mountains of the Canary Islands, disrupt the circulate of wind and trigger the air and clouds to spin in a spiral form that resembles hurricanes.
The wind depth impacts the sample of the cloud swirls. These vortices are pushed by prevailing winds, which NESDIS says can change seasonally and trigger variations within the course and construction of the vortices.

NESDIS says Guadalupe Island (off the western coast of Mexico’s Baja California Peninsula) and the Canary Islands and Cape Verde Islands (off the western coast of Africa) are frequent spots for von Karman vortices type. As well as, satellites have additionally captured pictures of the spinning clouds over the Juan Fernandez Islands off the coast of Chile.
They’ve additionally been noticed close to Tristan da Cunha, a distant volcanic island within the South Atlantic Ocean; Jeju Island, South Korea’s largest island; and the Kuril Islands, a volcanic archipelago within the Pacific Ocean, in keeping with NESDIS.
