Query: Vertical Tracer Mixing in Hot Jupiter Atmospheres   Aerosols appear to be ubiquitous in close-in gas giant atmospheres, and
disequilibrium chemistry likely impacts the emergent spectra of these planets.
Lofted aerosols and disequilibrium chemistry are caused by vigorous vertical
transport in these heavily irradiated atmospheres. Here we numerically and
analytically investigate how vertical transport should change over the
parameter space of spin-synchronized gas giants. In order to understand how
tracer transport depends on planetary parameters, we develop an analytic theory
to predict vertical velocities and mixing rates ($K_\mathrm{zz}$) and compare
the results to our numerical experiments. We find that both our theory and
numerical simulations predict that, if the vertical mixing rate is described by
an eddy diffusivity, then this eddy diffusivity $K_\mathrm{zz}$ should increase
with increasing equilibrium temperature, decreasing frictional drag strength,
and increasing chemical loss timescales. We find that the transition in our
numerical simulations between circulation dominated by a superrotating jet and
that with solely day-to-night flow causes a marked change in the vertical
velocity structure and tracer distribution. The mixing ratio of passive tracers
is greatest for intermediate drag strengths that corresponds to this transition
between a superrotating jet with columnar vertical velocity structure and
day-to-night flow with upwelling on the dayside and downwelling on the
nightside. Lastly, we present analytic solutions for $K_\mathrm{zz}$ as a
function of planetary effective temperature, chemical loss timescales, and
other parameters, for use as input to one-dimensional chemistry models of
spin-synchronized gas giant atmospheres.
