The exploration of the Jovian system (Jupiter and its natural satellites) is of prime interest for present (Juno NASA’s mission) and upcoming (Juice ESA’s mission) spacecraft missions. This archetypal planetary system constitutes, in a way, a miniature of the solar system and other unachievable exosystems. The laboratory project presented in this movie focuses on Jupiter internal dynamics, which is of crucial interest as it sets the whole planetary environment, including the giant magnetosphere, in which an incredible diversity of celestial bodies and potentially certain forms of life are enclosed. This video try to answer the question about what could be at the origin of zonal Winds on Jupiter.

Movie of flow direct observation at 75 rotation per minutes. From the top lid camera fixed in the rotating frame, we record a 2 minutes movie accelerated 6 times, using black Indian ink as a flow tracer. Record initiates after 3000 rotation times when black ink is injected at two diametrically opposed locations on the free surface. The center of the frame corresponds to the center of the cylindrical tank (planetary pole). Within the first 10 seconds of the movie, ink is rapidly advected in the azimuthal direction by the zonal jets, while radial transport is inhibited. Then prograde and retrograde motions clearly appear. Small-scale mixing is clearly visible at the interface between two adjacent jets.
