Saturn’s gravitational field induced by its equatorially antisymmetric zonal winds

Anderson, John D.; Schubert, Gerald; Kong, Dali +1 more

The cloud-level zonal winds of Saturn are marked by a substantial equatorially antisymmetric component with a speed of about 50ms^-1 which, if they are sufficiently deep, can produce measurable odd zonal gravitational coefficients ΔJ _2k+1, k = 1, 2, 3, 4. This study, based on solutions of the thermal-gravitational wind equatio…
