Jupiter has a metallic Hydrogen core that creates a Magnetosphere similar to the one created by Earth's Iron core. Scientists have known that Jupiter generates more energy than it receives from the Sun, but how it affectes the Atmosphere below the surface layer of clouds was unclear. They are still trying to work out the way the Atmosphere is affected by the combination of these energy sources, but they are learning to make a distinction between the two effects. This data shows effects that to be a result of Energy generated by Jupiter. They are thought to be below any possible influence of the sun. (Of course the scientists could always be surprised again. That seems to happen fairly often.)

So, it looks like Arthur C. Clarke had it right about Jupiter in his book, 2010
