Since magnetic field is frozen into core. Climate and atmosphere. Tilt of Jupiter's equator from orbital plane only 3 degrees. Has cloud layers - complicated chemistry and turbulent motions. Total thickness is 80 km.
Colors are due to holes in upper atmosphere.
Bright zones - above upward moving currents. Dark belts - material is sinking like storm systems on Earth but stretched all the way around Jupiter due to rapid rotation. Great Red Spot Giant cyclone 4x radius of Earth. Rotates counterclockwise each 6 days. Jupiter emits 2x as much heat as it receives from the Sun.
