The number and location of Jupiter's circumpolar cyclones explained by vorticity dynamics

N Gavriel, Y Kaspi - Nature geoscience, 2021 - nature.com
The Juno mission observed that both poles of Jupiter have polar cyclones that are
surrounded by a ring of circumpolar cyclones (CPCs). The north pole holds eight CPCs and …

Long-term tracking of circumpolar cyclones on Jupiter from polar observations with JunoCam

F Tabataba-Vakili, JH Rogers, G Eichstädt, GS Orton… - Icarus, 2020 - Elsevier
We use observations from the JunoCam instrument on the Juno spacecraft to map the polar
regions of Jupiter between 2016 and 2018. These polar maps track the long-term evolution …

Modeling the stability of polygonal patterns of vortices at the poles of Jupiter as revealed by the Juno spacecraft

C Li, AP Ingersoll, AP Klipfel… - Proceedings of the …, 2020 - National Acad Sciences
From its pole-to-pole orbit, the Juno spacecraft discovered arrays of cyclonic vortices in
polygonal patterns around the poles of Jupiter. In the north, there are eight vortices around a …

The climate system and the second law of thermodynamics

MS Singh, ME O'Neill - Reviews of Modern Physics, 2022 - APS
The second law of thermodynamics implies a relationship between the net entropy export by
Earth and its internal irreversible entropy production. The application of this constraint for the …
