Beschreibungen/Notizen

• Jupiter's banded appearance may appear unchanging to the casual observer, but closer inspection reveals a dynamic, ever‐changing system of belts and zones with distinct cycles of activity. Identification of these long‐term cycles requires access to data sets spanning multiple Jovian years, but explaining them requires multispectral characterization of the thermal, chemical, and aerosol changes associated with visible color variations. The Earth‐based support campaign for Juno's exploration of Jupiter has already characterized two upheaval events in the equatorial and temperate belts that are part of long‐term Jovian cycles, whose underlying sources could be revealed by Juno's exploration of Jupiter's deep atmosphere. Key Points Jupiter's dark belts exhibit cycles of plume activity and color changes over long timescales A jet stream outbreak in Jupiter's North Temperate Belt was captured shortly after Juno's arrival Juno may help to reveal the sources generating Jupiter's belt/zone variability
