Constraints on the latitudinal profile of Jupiter’s deep 1 jets 2

The observed zonal winds at Jupiter’s cloud tops have been shown to be closely linked 21 to the asymmetric part of the planet’s measured gravity field. Here we examine to what 22 extent, and at which latitudes, must the flows at depth resemble those at the cloud level 23 in order to match the gravity signal. We show, using both the symmetric and asymmet- 24 ric parts of the measured gravity field, that the observed cloud-level wind profile between 25 25 ◦ S and 25 ◦ N must extend unaltered to depths of thousands of kilometers. Poleward, 26 the midlatitude deep jets also contribute to the gravity signal, but might differ some- 27 what from the cloud-level winds. We analyze the likelihood of this difference and give 28 bounds to its strength. We also find that to match the gravity measurements, the winds 29 must project inward in the direction parallel to Jupiter’s spin axis, and decay inward in 30 the radial direction. 31
