Jupiter’s fearsome polar cyclones are driven by similar forces to the huge ocean vortices on Earth

Studies suggest that Jupiter’s horrific polar cyclones are driven by forces similar to the giant ocean vortices on Earth.

  • Researchers examined a series of infrared images of Jupiter’s polar cyclone
  • Next, we calculated the speed, height, and other factors of these storms.
  • The team discovered that the storm was as powered as a marine cyclone.










A new study reveals that the dreaded cyclone that stretches across Jupiter’s poles is driven by forces that resemble the giant ocean vortices on Earth.

Pictures of violent eddy in the polar regions of Jupiter’s gastric atmosphere were sent back to Earth by NASA’s Juneau spacecraft for study by scientists.

Using these images, a team at the University of California, San Diego compared Jupiter’s eddy motion and physics with a large cyclone on Earth.

The team says that understanding Jupiter’s energy system, which is much larger than Earth, may help explain the mechanisms working on our own planets.

Numerous swirling clouds of Jupiter’s dynamic north-south temperate belt are captured in this image from NASA’s Juno spacecraft.

Jupiter: Basic

Jupiter is the fifth planet from the Sun and the largest in the solar system.

It is a huge gas sphere, mainly made of hydrogen and helium, containing some heavy elements.

“Jupiter’s familiar stripes and swirls are actually cold, windy clouds of ammonia and water floating in the atmosphere of hydrogen and helium,” NASA said.

“Jupiter’s iconic Great Red Spot is a giant storm larger than Earth, which has been furious for hundreds of years.”

Planets are twice as large as all other planets combined, and the Great Red Spot alone is large enough to fit the entire Earth inside.

One spacecraft – NASA’s Juno Orbiter – is currently exploring this huge world.

Using a series of images in addition to the principles used in geophysical fluid dynamics, lead author Lia Siegelman states that moist convection (when hotter, less dense air rises) drives Jupiter’s cyclones. I found evidence to prove the long-standing hypothesis.

“When we saw the richness of turbulence around the Jupiter cyclone with all filaments and small turbulence, it reminded us of the turbulence you saw in the ocean around the vortex,” the researchers explained. ..

“These are especially noticeable in high-resolution satellite images of plankton bloom, for example.”

Understanding Jupiter’s energy system, which is on a much larger scale than Earth, is the physical working on our own planet by highlighting some energy routes that may also exist on Earth. It also helps to understand the mechanism.

“It’s fascinating to be able to study distant planets and find physics that apply to them,” she said. “It raises the question, do these processes also apply to our own blue dots?”

Juno was the first spacecraft to capture images of Jupiter’s poles, as previous satellites orbited the equatorial region of the Bigger Than Worlds.

Juno is equipped with two camera systems. One is for visible light images and the other uses the Jupiter Infrared Aurora Mapper (JIRAM) to capture thermal features.

The team was able to study infrared images of the Arctic region, especially around polar vortex clusters, and calculate wind speed and direction from those images. They did this by tracking the movement of clouds between images.

Next, we interpreted the infrared image in terms of cloud thickness, discovered that the hot regions corresponded to thin clouds, and provided a deeper view of the atmosphere.

Cold regions represent thick cloud cover and cover Jupiter’s atmosphere. The combination of these provides clues to the energy of the system that produces the eddy.

Because Jupiter’s clouds form when hotter, less dense air rises, researchers have found that rapidly rising air in the clouds supplies large circumpolar stars and polar cyclones on a large scale. I discovered that it functions as an energy source.

Scientists have been able to study these polar cyclones since Juno arrived at the Jupiter system in 2016.

Eight of these cyclones occur in Jupiter’s North Pole and five in the South Pole, according to US researchers.

Using these images, a team at the University of California, San Diego compared Jupiter's eddy motion and physics with a large cyclone on Earth.

These storms have existed since the first observations five years ago, but researchers do not know how they occurred or how long they circulated, but moist convection they. I now know that it supports.

Researchers first hypothesized this energy transfer after observing lightning in a Jupiter storm.

Junho will continue to orbit Jupiter until 2025, providing researchers and the general public with novel images of the planet and its extensive lunar system.

The findings are published in the journal Nature Physics.

NASA’s Juneau exploring Jupiter reveals the secrets of the largest planet in our solar system

The Juno probe reached Jupiter in 2016 after traveling 1.8 billion miles from Earth for five years.

The Juno probe reached Jupiter in 2016 after traveling 1.8 billion miles from Earth for five years.

The Juno probe reached Jupiter on July 4, 2016, after a five-year journey of 1.8 billion miles (2.8 billion km) from Earth.

After a successful braking operation, it entered a long polar orbit that flew within 3,100 miles (5,000 km) of the planet’s swirling cloud tops.

The probe skimmed once every two weeks within just 2,600 miles (4,200 km) of the planet’s clouds. This is too close to provide global coverage on a single image.

No other spacecraft has ever orbited so close to Jupiter, but the other two have plummeted to destroy the atmosphere.

To complete that dangerous mission, Juneau survived a radiant storm that lifted a circuit generated by Jupiter’s strong magnetic field.

Large vortices of high-energy particles that move at near the speed of light are the harshest radiative environments in the solar system.

To address this situation, the spacecraft was protected by special radiation-resistant wiring and sensor shields.

Its most important “brain” (spacecraft flight computer) was housed in an armored vault made of titanium and weighing about 400 pounds (172 kg).

This aircraft is expected to study the composition of the planet’s atmosphere until 2025.
