Calculations predict that, if Jupiter's observed zonal flows persist to a depth ~1000 km below the cloud layers (corresponding to a pressure ~10 kbar), they will produce gravity anomalies on the order of a few mgal in high-degree zonal components of the gravitational field, referenced to the field expanded to tenth degree. This signature would be detectable by a low-periapse Jupiter orbiter with a sensitivity to accelerations at the same level as the Galileo orbiter.
