  The observed zonal winds at Jupiter's cloud tops have been shown to be
closely linked to the asymmetric part of the planet's measured gravity field.
However, other measurements suggest that in some latitudinal regions the flow
below the clouds might be somewhat different from the observed cloud-level
winds. Here we show, using both the symmetric and asymmetric parts of the
measured gravity field, that the observed cloud-level wind profile between
25$^{\circ}$S and 25$^{\circ}$N must extend unaltered to depths of thousands of
kilometers. Poleward, the midlatitude deep jets also contribute to the gravity
signal, but might differ somewhat from the cloud-level winds. We analyze the
likelihood of this difference and give bounds to its strength. We also find
that to match the gravity measurements, the winds must project inward in the
direction parallel to Jupiter's spin axis, and that their decay inward should
be in the radial direction.
