Ocean physics comes up to explain Jupiter’s atmospheric vortices

(ORDO NEWS) — The Juno satellite (“Juno”) NASA, which moves in the Jupiter system and its 79 satellites, sends high-quality images of the Jupiter system to Earth, and these images allowed oceanographers on our planet, who previously studied the Earth’s oceans, to see amazing similarities in the movement of water flows in the Earth oceans and streams of dense gas in the vicinity of the poles of Jupiter and assume the unity of the driving forces of these streams.

Lead author Lia Siegelman, an oceanographer at the Scripps Institute of Oceanography at the University of California, San Diego, USA, decided to conduct her research after she noticed that atmospheric eddies around Jupiter’s poles resemble the oceanic eddies she studied. while in graduate school.

Using a set of imagery and principles of geophysical fluid dynamics, Siegelman and her team were able to prove the long-standing assumption that wet convection – when hot, less dense air rises upward – is responsible for the formation of these atmospheric vortices.

Siegelman and her colleagues analyzed a set of infrared images of Jupiter’s northern circumpolar region, and in particular, a group of polar vortices. From these images, scientists were able to calculate the wind speed and direction from the movement of the clouds.

In the next phase of the work, the team interpreted the infrared images in terms of the thickness of the clouds. Hot regions corresponded to thin clouds, and in these regions one could look deep into the planet’s cloud cover. The cold areas were covered with thick, impenetrable clouds.

These findings allowed the authors to better understand the energetics of our solar system. Because clouds on Jupiter form when hot, less dense air rises upward, the researchers have found that this skyrocketing air is a source of energy to power larger structures, up to polar atmospheric vortices.
