A novel unified hydrodynamic model proposes a single mechanism to explain the contrasting equatorial jet stream directions on gas giants (eastward on Jupiter/Saturn) and ice giants (westward on Uranus ...

Top: The Rossby wavenumber-5 pattern is shown with the black line (median) and gray ribbon (full zonal range of preferred phase). The authors define the wave5-PC index to express the number of weeks ...
