Both Earth and Jupiter have equatorial oscillations in their atmospheres. An analysis of over two decades of observations of Saturn's stratospheric emission finds a similar oscillation. The period is 14.8 ± 1.2 terrestrial years, roughly half of Saturn's year, suggesting the influence of seasonal forcing, as is the case with the Earth's semi-annual oscillation.
