Firstly, there's a definitive rotation around the pole.
Secondly, there's an obvious black spot in the center of the cloud formation. It seems at times to take on a hexagonal shape, much akin to the to 'polar storms' (moniker courtesy the brilliant boys and girls at NASA) found on the other heavy atmosphere planets they've investigated so far.
It's already been pointed out by Mr. Thornhill that a characteristic of Birkland currents is hexagonal lobing- seen at the poles of the heavy atmosphere planets and many hexagonally-shaped craters on Mars, Mercury, and many moons in our solar system.
I think that clinches the 'electrical connection' quite nicely- those clouds are a layer of plasma in the high atmosphere entering glow mode, most likely co-related to the new solar cycle.
That's my take on it, anyway. I have no proof, I'm a layman, and I can think however I wanna!
