Query: Lightning generation in moist convective clouds and constraints on the
  water abundance in Jupiter   Recent Juno observations have greatly extended the temporal and spatial
coverage of lightning detection on Jupiter. We use these data to constrain a
model of moist convection and lightning generation in Jupiter's atmosphere, and
derive a roughly solar abundance of water at the base of the water cloud.
Shallow lightning, observed by Juno (Becker et al., 2020, Nature, 584, 55-58)
and defined as flashes originating at altitudes corresponding to pressure less
than 2 bars, is reproduced, as is lightning at a deeper range of pressures,
including those below the water cloud base. It is found that the generation of
lightning requires ammonia to stabilize liquid water at altitudes corresponding
to sub-freezing temperatures. We find a range of local water abundances in
which lightning is possible, including subsolar values of water--consistent
with other determinations of deep oxygen abundance.
