  In Paper II we described the extreme changes in Jupiter's North Equatorial
Belt (NEB) which took place in 2011-12: quiescence, narrowing, and fading of
the belt, along with acceleration of the prograde NEBs jet to super-fast speed.
Here we describe how this anomalous state was terminated in 2012, in a rapid
and vigorous disturbance known as a NEB Revival, the first in living memory. At
the same time, the North Temperate Belt (NTB) had entered a similar preparatory
state, which was terminated by a NTB Revival initiated by a typical outbreak on
the super-fast NTBs jet. The two concurrent Revivals appeared to constitute a
'great northern upheaval' that extended from the equator to 38N, which may have
been the first such event ever recorded. We compare this dual event with the
more typical 'Global Upheavals', which consist of near-simultaneous Revivals of
the NTB and the South Equatorial Belt (SEB), along with equatorial coloration,
and we discuss the current understanding of Global Upheavals.
