Why is there a hexagonal storm on Saturns northern pole ?

It's a common structure in fluid dynamics, it even exists in hurricanes on Earth, however the cold temperatures on Saturn enhances the effect.

The effect can be duplicated in a spinning pail of water with some food coloring.

interior the North a hexagonal formation outlining a critical maelstrom maintains to be unexplained. in spite of wind speeds of 530 kilometers in line with hour interior the hexagon and 500 kilometers in line with hour outdoors, the hexagon does not seem to pass different than with the planet's rotation. The north polar hexagon became seen in attitude by the two Voyager probes as they flew by the gas substantial in November 1980 and then in August 1981, so it incredibly is a protracted-lived phenomenon. The imaging team maintains to income archives in hopes of looking a potential by which convection can manage and shield a six-sided formation in a spinning cloud layer.

I went through this storm when I visited Saturn yesterday. The aliens told me not to worry about it.
