Washington Post headline: Uranus might be full of surprises
Scientists used to think that things were pretty chill over in the south hemisphere of Uranus. In fact, they thought it was one of the calmest regions of any of the gas giants. But in analyzing images taken nearly three decades ago by NASA's Voyager-2 spacecraft, researchers think they've found a kerfuffle of activity — which might indicate that there's something unusual about the planet's interior.
If you look at these old photos of Uranus, the planet appears to be a stark, featureless ball. And even to scientists, who were able to identify more lively features of the gas giant, it was still considered pretty bland.
But when University of Arizona astronomer Erich Karkoschka took another look, he saw a different story. He presented his findings this week at the meeting of the Division for Planetary Science of the American Astronomical Association.
Karkoshchka believes that Uranus's southern hemisphere rotates in a way never before seen in gas giants. A gas planet's thick atmosphere, filled with clouds, typically shows the same rate of rotation at the top and bottom. But on Uranus, it seems, the southern hemisphere is cycling much more quickly than up north — as much as 15 percent faster.
"The unusual rotation of high southern latitudes of Uranus is probably due to an unusual feature in the interior of Uranus," Karkoshcka said in a statement. "While the nature of the feature and its interaction with the atmosphere are not yet known, the fact that I found this unusual rotation offers new possibilities to learn about the interior of a giant planet."

OK........... too easy to start a joke but go ahead
= new reply since forum marked as read
It was messy, but it wasn't a surprise. 
So the southern and northern hemispheres alternatively point toward Sol in half of Uranus' orbit of some 84 Terran years.
To me, it is not at all surprising that Uranian poles have some weirdness.

No worries, no joke. It's not pronounced that way anyway. It's UR-ah-nus, not ur-AY-nus
We've known about its rotation and orbit for many decades. But my point is knowing that it rotates on its side with respect to the ecliptic, one could hypothesize that the Uranian pole pointing continuously towards the Sun for decades as it revolves around old Sol might have weird weather. Even at that distance, the Sun has effects.
But I am just spit balling here.
In the order of increasing distance from the planet the 13 known rings are designated 1986U2R/ζ, 6, 5, 4, α, β, η, γ, δ, λ, ε, ν and μ.
