Query: Formation of Jets and Equatorial Superrotation on Jupiter   The zonal flow in Jupiter's upper troposphere is organized into alternating
retrograde and prograde jets, with a prograde (superrotating) jet at the
equator. Existing models posit as the driver of the flow either differential
radiative heating of the atmosphere or intrinsic heat fluxes emanating from the
deep interior; however, they do not reproduce all large-scale features of
Jupiter's jets and thermal structure. Here it is shown that the difficulties in
accounting for Jupiter's jets and thermal structure resolve if the effects of
differential radiative heating and intrinsic heat fluxes are considered
together, and if upper-tropospheric dynamics are linked to a
magnetohydrodynamic (MHD) drag that acts deep in the atmosphere. Baroclinic
eddies generated by differential radiative heating can account for the
off-equatorial jets; meridionally propagating equatorial Rossby waves generated
by intrinsic convective heat fluxes can account for the equatorial
superrotation. The zonal flow extends deeply into the atmosphere, with its
speed changing with depth, up to depths at which the MHD drag acts. The theory
is supported by simulations with an energetically consistent general
circulation model of Jupiter's outer atmosphere. A simulation that incorporates
differential radiative heating and intrinsic heat fluxes reproduces Jupiter's
observed jets and thermal structure and makes testable predictions about as-yet
unobserved aspects thereof. A control simulation that incorporates only
differential radiative heating but not intrinsic heat fluxes produces
off-equatorial jets but no equatorial superrotation; another control simulation
that incorporates only intrinsic heat fluxes but not differential radiative
heating produces equatorial superrotation but no off-equatorial jets.
