The turbulent centuries-old whirlpool of Jupiter's Great Red Spot was shaken but not destroyed by a series of
Smaller storms force chunks of redsclouds flake off, thus reducing the larger storm. But new research has shown that these violations are "superficial." They are visible to us, but they are only on the surface of the red spot, without affecting its full depth.
The new study was published in the Journal ofGeophysical Research: Planets, AGU's journal dedicated to the study of the formation and evolution of planets, moons and objects in our solar system and beyond.
"Intense vorticity [Big redspots], together with its large size and depth compared to interacting vortices, guarantees a long service life, ”explains Agustín Sánchez-Lavega, professor of applied physics at the University of the Basque Country in Bilbao, Spain and lead author of the new paper. As the larger storm absorbs these smaller storms, it "gets its energy from the energy of their rotation."
Jupiter's red spot is shrinking at leastleast the last 150 years. During this time, it decreased from about 40 thousand kilometers in 1879 to 15 thousand kilometers today. Researchers are still unsure about the reasons for this process and how the stain was originally formed. New data show that it is small anticyclones that can help support the Great Red Spot.
