Instability of the zonal jets and longitudinal thermal waves in a Jovian atmosphereJupiter atmosphere observations conducted during the Voyager 1 and 2 encounters indicate slowly moving large-scale features; ground-based measurements with the NASA IR Telescope Facility have noted large scale waves that are either fixed or slowly moving relative to system III. These observations suggest features originating deep in the atmosphere. The present suggestion of an alternative source proceeds from a model of the jets which views the observed waves as due to the quasigeostrophic instability of the jets in the upper troposphere; these are of sufficient duration to give the impression of permanence under observational conditions.
