  Previously, we have presented the first study to investigate the response of
the Jovian thermosphere to transient variations in solar wind dynamic pressure,
using a coupled, azimuthally symmetric global circulation model coupled with a
simple magnetosphere model. This work (Yates et al., 2013, submitted) described
the response of thermospheric flows, momentum sources, and the
magnetosphere-ionosphere coupling currents to transient compressions and
expansions in the magnetosphere. The present study describes the response of
thermospheric heating, cooling and the auroral emissions to the aforementioned
transient events. We find that transient compressions and expansions, on time
scales <= 3 hours, cause at least a factor of two increase in Joule heating per
unit volume. Ion drag significantly changes the kinetic energy of the
thermospheric neutrals depending on whether the magnetosphere is compressed or
expanded. These processes lead to local temperature variations >= 25 K and a
~2000 TW increase in the total power dissipated in the thermosphere. In terms
of auroral processes, transient compressions increase main oval UV emission by
a factor of ~4.5 whilst transient expansions increase this main emission by a
more modest 37%. Both types of transient event cause shifts in the position of
the main oval, of up to 1 deg latitude.
