Given the size and variable nature of the great red spot is it right to assume that the source of the energy is just from the flow of the atmosphere?

I will not add my idea because that is (well not even under consideration) but has the driving source of the GRS ever been thought to be from within the planet in much the same way the magnetic field lines are that drive the sun?

It is noted that Jupiter gives off more heat than it receives and that there is an exceptionally high current detected indicating possibly that the source is internal and not a creation of wind.
