COMPARISON OF GALILEO PROBE AND EARTH-BASED TRANSLATION RATES OF JUPITER EQUATORIAL CLOUDS

The Doppler wind speeds derived from Galileo probe data are comparable with the maximum translation speeds observed in the equatorial zone b y Voyager 1 and the Hubble Space Telescope, Slower published values of east-west winds are based on measurements of larger features and shou ld be interpreted as translation rates of large weather systems intera cting with the wind. The nature of the hot-spot region that the Galile o probe entered is compatible with a high-speed jet at 6 degrees north , The hot spot is associated with an equatorial weather system that sp ans 5 degrees of latitude and translates at 103 meters per second.
