A survey of small-scale waves and wave-like phenomena in Jupiter's atmosphere detected by JunoCam

In the first 20 orbits of the Juno spacecraft around Jupiter, we have identified a variety of wave-like features in images made by its public-outreach camera, JunoCam.  Because of Juno’s unprecedented and repeated proximity to Jupiter’s cloud tops during its close approaches, JunoCam has detected more wave structures than any previous surveys.  Most of the waves appear in long wave packets, oriented east-west and populated by narrow wave crests.  Spacing between crests were measured as small as ~30 km, shorter than any previously measured.  Some waves are associated with atmospheric features, but others are not ostensibly associated with any visible cloud phenomena and thus may be generated by dynamical forcing below the visible cloud tops.    Some waves also appear to be converging and others appear to be overlapping, possibly at different atmospheric levels.  Another type of wave has a series of fronts that appear to be radiating outward from the center of a cyclone.  Most of these wa...
