The stability over time of the zonal jets on the giant planets has been debated. An analysis of observations from the Cassini spacecraft reveals an acceleration of wind velocities in Saturn’s high-altitude equatorial jet between 2004 and 2009, by 20 m s−1 at tropopause level and by 60 m s−1 in the stratosphere.
