The atmosphere of Venus contains strong winds and is said to have a "super rotation" because the atmosphere (above a certain altitude) moves faster than what the ground does.
No one can disagree with the fact that the atmosphere moves faster than the ground at most altitudes. However, does the wind pattern literally rotate around the planet as the common wording implies? Or... does the atmosphere actually zig-zag from the day side to the night side (nonetheless faster than the ground movement), making the common description of "super rotation" a popular misconception? This is one case where I think that pictures ask the question better than text:
This is just one example. I think that the underlying notion is pretty obvious.
This illustration comes from the Wikimedia Commons. It is, in fact, the most detailed illustration of the wind pattern on Venus that Wikipedia has. In spite of my trying, I can not find any evidence that the image was ever depreciated and removed from the relevant English page due to changing science, or the less relevant page for that matter. The image timestamp actually predates the corresponding article, which casts suspicion on the accuracy of those time stamps in general. Overall, the use history is very unclear to me. Also note, here is a site which might be the source and contains the diagram in English.
Please do not mistake this illustration for the one currently displayed on the Wikipedia page, since that one shows Meridional flow only. This question is strictly about zonal flow.
Mechanistically, I can understand the Zig Zag a lot better since the sun's heat is the driving force. If the pattern was a true rotating, then where is the driving force coming from? There's not choked flow coming from the cold side or anything like that, so the driving force from the expansion of the gas due to heating can't exert a net-force along latitude lines. But it's difficult to track down the science, since I can't tell who is just incorrectly recounting something they heard from somewhere else, and who actually understands.
So which is it? Does the wind pattern really rotate, or does it just zig zag?
