The atmospheres of the Earth, Jupiter and Saturn show a remarkably similar phenomenon in their equatorial regions: vertical, cyclic patterns, descending alternate temperatures and wind systems that repeat over a period of several years.
These patterns, known as Quasi Periodic Oscillation (QPO) in Saturn and Quasi-Quadriennial Oscillation (QQO) in Jupiter, due to their similarities with the so-called Quasi Biennial Oscillation (QBO) of the Earth, seem to be a defining characteristic of the middle layers of a planetary atmosphere.
