Event Details & Abstract: 

Refreshments served 30 minutes prior to start of talk in front of the JILA Auditorium. Jupiter is girded by about 30 strong atmospheric jets — visible atmospheric cloud bands and belts that encircle the entire planet along various lines of latitude. NASA's Juno spacecraft is presently in orbit around Jupiter and is acquiring striking images of the Jovian cloud layer in addition to high resolution gravity and magnetic field data. One of the main goals of Juno is to understand whether the Jovian Jets are trapped in the relatively shallow weather layer, or if they extend to much greater depths into the planet’s interior.

In this colloquium, I will discuss how Jovian-style atmospheric jets and vortices form. I will then go over the recent results in which Jovian-style jet flows were generated in a rotating jacuzzi-esque laboratory experiment (Cabanes et al., NatPhys 2017). Our lab predictions will then be compared to the analysis of the presently available Juno data. Finally, future directions for this unique lab set-up will be discussed.
