Mysteries Swirl Around Cyclones At Saturn's Poles

Riding with Robots writes "New images of Saturn from the robotic spacecraft Cassini are shedding new light on monstrous storms that swirl at both poles of the ringed planet. 'These are truly massive cyclones, hundreds of times stronger than the most giant hurricanes on Earth,' said one mission scientist. Cumulus clouds twirl around the vortices, betraying the presence of giant thunderstorms lurking beneath. But the storms do not disturb the bizarre hexagonal cloud formation previously reported."

    Don't you think this kind of research will help us better understand our own planet? After all, you don't get to understand how humans work by only studying humans. You study related -- and not so related -- animals and plants.

    I would be curious to know how far down these things go. They look like Taylor columns to me, and in principle could go all the way to the other side, assuming there isn't a rocky core down there somewhere.

      Rotating fluids that are perturbed tend to form columns parallel to the axis of rotation called Taylor columns, after G.I. Taylor. On the Earth, these are sometimes seen over seamounts in the oceans, and back when people assumed that Jupiter had a surface, it was hypothesized that the Great Red Spot was a taylor column over an obstruction on the surface below. This now seems highly unlikely, as a solid surface seems highly unlikely. Some more theory is here.

      More recently, it has been hypothesized that the belts of the gas giants Jupiter and Saturn (which are organized in pairs at opposite latitudes) may be Taylor columns (i.e., that they may extend part or all the way through the planet as cylinders, keeping the same distance from the rotation axis). A Taylor column at the pole could in principle go all the way through the planet, if there was nothing below it, or could mark the size of a rocky core, thousands of kilometers down. Thus my original question.

      This explains the idea pretty well :

      The proposed atmospheric cylinders were first demonstrated in a series of laboratory experiments 25 years ago to chart atmospheric flow in a wholly gaseous planet. Friederich Busse, University of Bayreuth, Germany, and John Hart, University of Colorado, Boulder, used liquid-filled spheres with high rotation speeds and imposed interior-exterior temperature differences. The experiments showed that the convective and most other disturbances in these fast-rotating spheres of fluid almost always produced cylindrical vortices parallel to the test vessel's spin axis, called Taylor columns.

    Instead of worrying about Saturn's cyclones, how about worrying about earth's cyclones, hurricanes, tornadoes and tsunamis?

    Lets reserve the funding for this within our own earth please. On one hand, people talk about making the earth "green" and on the other hand, they blow up useful money into researching how the universe was built, whether Mars has life on it, how cyclones and tsunamis occur on Saturn. Does the scientific community not have its priorities right and consistent?

    Do they come with unusual cloud formations?

    The hexagonal clouds are not a mystery. They in fact prove that there are legislators somewhere else even dumber than the ones we choose for ourselves. Obviously the government of Saturn has declared the value of PI to be exactly 3 and the clouds are only obeying the law.

    Speaking as a physicist, physical insight is always increased when you look at a broader problem. Studying cyclones only on the Earth is like trying to understand gravity while limiting your observations to distances between the ground and the height of a tree. You can come up with a great linear gravitational potential function, but you will never understand the physical significance of gravity. Only when you look at the broader problem do you begin to understand how gravity actually works. From there you can make assumptions, develop the math, and use it as a stepping stone to jumpstart other ideas, like classical electrodynamics (which itself provided the stepping stone for the complete rewrite of gravitational theory).

    The benefits of studying weather patterns and geology outside of the narrow range that we observe on the Earth could be enormous. By observing the bizarre, we might be able to gain some insight into the mundane. These cyclones are a perfect chance. We have a pretty good idea on how cyclones work on the Earth, but the cyclones on Saturn are a mystery. By unraveling how these cyclones work, it should be possible to make a much more robust theory on how all cyclones will work.

    The hexagonal clouds are no mystery. You see, Saturn is far away. It was never meant to be looked at up close. The Designers just didn't bother to waste a lot of polygons on it to approximate a sphere. It's just a low-poly model with some texturing tricks to hide the edges.

    If we want to see it in higher resolution we have to get our spacecraft new graphics cards, that's all.
