With such a huge transfer of momentum -- a day on Venus is +/- 3 minutes the previous one -- the winds on the ground must be crazy!

- munk-a 5y agoYea actually, prior to reading this article I always thought of the atmosphere as a mostly static shell that just sorta floats around planets - it's interesting to consider how, when the wind pushes on a mountain the mountain pushes back (not literally of course) and that can cause subtle variations in day cycle on earth that could be influenced by spikes in externally acquired heat in differing parts of the atmosphere - but it's crazy to think how much more dramatic the effect is on Venus.
- qayxc 5y agoThe winds on Venus' surface are actually pretty tame ("light breeze", 1 Beaufort, 0.5 to 1 m/s) [1]. Problem is, that even this very slight wind packs a considerable punch at 92 bars of pressure and is comparable to a category 4 hurricane on Earth in terms of power (i.e. it would roughly translate to about 90 m/s; 325 km/h; 200 mph on Earth).
