Analysis of numerical modelling of Jupiter's atmospheric activities

Placed at 484 milion of miles from the Sun, Jupiter arouses a great interest in the scientific community for several reasons. Named as the king of the Roman gods, the first observations of this planet can be located during the 7th-8th century BC, suggesting how humans have always been interested and fascinated by what's there beyond the "visible sky". Jupiter has represented for many years the concept of the unknown, owing to the difficulty in observing not only the planet itself but what was under its atmosphere which, through many missions such as Juno, turned out to be the most characteristic element of this planet: atmospheric outbursts, violent thunderstorms and the longevity of cyclonic and anticyclonic spots are only some of the features that most impressed the researchers. Various models of the jovian turbulent dynamic activity have been presented during the years, and especially in the last ones some similarities have been outlined between Jupiter's vortex dynamics and the Earth's oceanic activities, proposing how the knowledge about the Earth has to be researched "outside". The uncertainties related to the inner part of the planet and the actual reasons of the survival of its main spots (with the Great Red Spot as the most famous one) are still present currently. In particular, this thesis work aims to investigate the behavior of the circumpolar cyclones that characterizes Jupiter's poles, by proceeding in two ways: a discussion of the main models of Jupiter's atmosphere reported in the last 40 years and a consequent attempt to explain the particular features of the vortex spots, such as their longevity or stable location.
