"...the clouds on the periphery of some of Jupiter's polar cyclones rotate counterclockwise, while the core of the cyclones rotate clockwise."
"Last year the Juno team reported on the cyclones of the south pole. At that time, Juno's Jovian Infrared Auroral Mapper instrument captured images of a new cyclone appearing to attempt to join the five established cyclones revolving around the massive central cyclone at the south pole.
"That sixth cyclone, the baby of the group, appeared to be changing the geometric configuration at the pole - from a pentagon to a hexagon," said Bolton. "But, alas, the attempt failed; the baby cyclone got kicked out, moved away, and eventually disappeared.""
Birkeland currents perhaps?
