Researchers understand the causes of “geometric storms” on Jupiter

US scientists have modeled storms on Jupiter and understood why they form geometric shapes. However, in order to understand their origin, a new mathematical model is needed.

In order to understand the origin of geometric cyclones on Jupiter, the researchers developed a computer model based on the size and speed of the hurricanes. They focused on what phenomena can keep these geometric patterns stable without merging with each other.

The researchers found that the stability of storms depends on how deeply the cyclones penetrate Jupiter’s atmosphere. In addition, they found anticyclone rings around each of them – rings of wind rotating in the opposite direction from the storm. Moreover, if its strength is too small, the cyclones merge, and if it is large, they are separated from each other.

Now scientists want to find out why most of the eddies remain average and allow the geometry of the storms to be preserved. “Right now, we have no idea what makes them maintain perfect strength. For this we need other models, ”they said.

In 2016, NASA’s Juno probe entered orbit around Jupiter and discovered giant cyclones geometrically arranged around the poles. At the planet’s North Pole, there are eight vortices surrounding the central vortex, and six at the South Pole.

“We were surprised that Jupiter’s poles are not like the poles of other planets,” said lead author Cheng Li, a planetary scientist at the University of California, Berkeley. “We have never seen anything like a cluster of cyclones in a strict structure before.”

According to their calculations, each giant storm has a width of 4 to 7 thousand kilometers, and they surround their poles at a distance of 8.7 thousand kilometers. They continue throughout the observation of the planet.
