The middle atmospheres of planets are driven by a combination of radiative heating and cooling, mean meridional motions, and vertically propagating waves (which originate in the deep troposphere). This paper reports infrared observations showing that Saturn has an equatorial oscillation like Earth's and Jupiter's, as well as a mid-latitude subsidence that may be associated with the equatorial motion.
