  Stratospheric heating, condensation, convective transport of non-equilibrium
species, and deep radiative energy transport are important processes in the
atmospheres of the solar jovian planets. They likely affect the atmospheres of
extrasolar giant planets and brown dwarfs as well. Stratospheric temperatures
control thermal fluxes in strong molecular bands, and may dramatically affect
observed spectra. Condensation processes affect the appearance of an object,
alter the abundances of atmospheric species, and influence the fluxes of both
reflected and emitted radiation. Convection can dredge up non-thermochemical
equilibrium species from the deep atmosphere to the observable atmosphere.
Finally deep radiative zones can limit the effectiveness of deep convection and
alter the boundary condition at which the planet radiates energy to space. Here
I discuss the role these processes may play in the atmospheres of brown dwarfs
and extrasolar giant planets.
