计算预测，如果观测到的木星纬向流持续到云层以下1000公里的深度（对应于类似于10千巴的压力），它们将在引力场的高度纬向分量中产生几毫克的重力异常，参考引力场扩展到10度。这一特征将被低近日点木星轨道器探测到，它对加速度的灵敏度与伽利略轨道器相同。(C) 1999学术出版社。
Calculations predict that, if Jupiter's observed zonal flows persist to a depth similar to 1000 km below the cloud layers (corresponding to a pressure similar to 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. (C) 1999 Academic Press.
