Dynamics of Saturn's great storm of 2010-2011 from Cassini ISS and RPWS

► We analyzed Saturn's Great Storm of 2010-2011 as seen by Cassini Orbiter. ► The new storm erupted from the String of Pearls feature. ► The new storm was the longest-lasting storm on Saturn in record. ► The storm spawned the largest tropospheric vortex ever seen on Saturn. ► We captured the convective storm's beginning and end using two instruments.
