These two Cassini images taken 23 minutes apart show many vortices and turbulent wakes in Saturn’s atmosphere. They also show the overall filamentary structure of the flow in the atmosphere. Many of the narrow cloud streaks that extend and curl over great distances maintain their integrity, rather than mixing with neighboring air parcels. This type of behavior is a characteristic of what scientists call “two-dimensional turbulence”.
