Jupiter, the colossus of the Solar System, hosts unique atmospheric phenomena that have puzzled scientists for centuries. Its atmosphere, composed primarily of hydrogen and helium, is the scene of violent storms and powerful winds that far exceed any meteorological phenomenon on Earth. Thanks to space missions like Juno and the James Webb mission, new secrets about this giant planet have been discovered. To learn more about the fascinating Jupiter, you can visit our article on the planet Jupiter.
One of Jupiter's greatest enigmas has always been the Great Red Spot., a colossal storm that has been active for over 150 years. However, new research has shown that its size is decreasing, and its structure is deeper than previously thought. Furthermore, recent observations have revealed that Jupiter's clouds are not composed solely of ammonia, but rather more complex combinations of chemical elements. To better understand the dynamics of the atmosphere, you can consult the atmosphere formation.
Jupiter's atmosphere: composition and structure
Jupiter's atmosphere is composed mainly of hydrogen and helium., with small traces of methane, ammonia, water vapor, and other compounds. These substances mix and react with each other, generating the impressive bands of color observed from Earth.
Jupiter's atmospheric layers are divided into three main ones: the troposphere, where the clouds and storms; the stratosphere, with unusual wind dynamics; and the thermosphere, which interacts with the planet's magnetic field. For more information on the satellites orbiting this gas giant, you can read our article on the Jupiter satellites.
The Great Red Spot: The Eternal Storm
The Great Red Spot is the largest storm in the Solar System, with a diameter larger than Earth. It is a high-pressure vortex that has persisted for centuries, fueled by powerful atmospheric currents. If you're interested in learning more about Jupiter's superstorm, be sure to check out the article titled the superstorm probe Juno.
Thanks to the Juno probe, it has been discovered that The Great Red Spot extends to a depth of about 500 kilometers., much more than previously believed. In addition, Its wind speed can reach 430 km/h, a figure far higher than any land-based cyclone.
Currents and winds: the dynamics of Jovian atmosphere
Jupiter has an extremely complex wind system, with powerful jet streams that exceed 500 km/h in its upper atmosphere. These streams create large bands of clouds moving in opposite directions, generating a characteristic pattern. To better visualize these climatic dynamics, you can watch the related video at YouTube.
Recent observations by the James Webb Telescope have identified a high-speed current in Jupiter's equatorial stratosphereThis current, which is about 4.800 km wide, moves at speeds greater than those of many land-based hurricanes.
Composition of Jupiter's clouds
Until recently, scientists believed that Jupiter's visible clouds were made of ammonia ice crystalsHowever, recent studies have shown that these clouds are actually more complex, containing ammonium hydrosulfide and particles produced by the interaction of ultraviolet radiation with atmospheric gases.

The Juno probe and its findings
Since arriving at Jupiter in 2016, Juno has provided unprecedented information about the planet's atmosphereIts instruments have made it possible to measure the depth of several storms, analyze the chemical composition of the atmosphere, and map Jupiter's magnetic field.
One of the most fascinating discoveries has been the existence of large cyclones at the planet's polesEight storms at the North Pole and five at the South Pole form stable structures that have remained unchanged for many years. To appreciate the beauty of these cyclones, you can read the article on the beauty of Jupiter's poles.
Advances in the exploration of Jupiter have unraveled many of the mysteries surrounding its atmosphere. The combination of observations from space telescopes like the James Webb telescope and missions like Juno continues to provide crucial data on its composition, storms, and climate dynamics. Many unanswered questions remain, making Jupiter a fascinating object of study for modern astronomy.
