A study conducted by an international team of researchers led by Agustín Sánchez-Lavega, professor of Physics at the UPV/EHU, reveals the existence of a rich diversity in the atmospheric phenomena confined inside Jupiter's spot as a result of the intense hurricane winds blowing around its periphery at speeds of about 450 km/hour.
The results are published in the Astronomical Journal. Jupiter's Great Red Spot, a long-lived, oval-shaped whirlwind measuring 20,000 km, is perhaps one of the most popular atmospheric phenomena in the solar system; according to this study, it contains cumulus clouds of clustered storms produced by the condensation of ammonia vapour, narrow gravity waves similar to those that form on the Earth when the wind blows on mountain summits. Yet calm reigns at its centre where the clouds move by rotating in the opposite direction at maximum speeds of only 25 km/hour.
Phenomena - Layer - Km - Thick - Roof
"These phenomena are confined to a thin layer only 50 km thick, which represents the roof of the clouds of the spot, while inside, the spot probably goes down to a depth of a couple of hundred kilometres," say the researchers. They used the images taken by the JunoCam during its close flyby across the Great Red Spot. These and other aspects of this phenomenon are the focus of the research that the Juno mission will be conducting over the next few years.
The Great Red Spot, observed for the first time with certainty 150 years ago, shows up through the telescope owing to...
