Scientists Reveal Why Jupiter and Saturn’s Polar Weather Looks So Different
Although Jupiter and Saturn are similar gas giants, their polar weather patterns are strikingly different. Saturn hosts a single, massive hexagonal storm at its north pole, while Jupiter features a central cyclone surrounded by smaller vortices. New simulations suggest the contrast may arise from differences deep inside the planets. A denser, “harder” interior could support Saturn’s dominant storm, whereas Jupiter’s softer interior may limit vortex growth, allowing multiple cyclones to coexist at its poles.
