Wind velocity has much to do with air density. The less dense the air, the greater the volocity, in general.

However, closer to the sun, the solar energy takes a more overriding role.

If you ever get a chance to see The Chronicles of Riddick, staring Vin Diesel, do so. There's an amazing scene involving what might happen along the terminator of a planet with an Earth-like atmosphere that is nevertheless in an orbit such as Mercury or at a more Earth-like orbit but around a far hotter star than is the Sun.

I found it fascinating!

Perception isn't reality. It's merely an abstraction thereof, and quite often not a very good one at that.

I am human. Fully human.

hmm ... interesting thought - but wouldn't that mean that the giant planets should have slower wind velocities than the terrestrial planets? And that Mars, Mercury, and some of the satellites, should have the highest?

Fun to watch, perhaps ... but I can't see a planet like that keeping an Earth-like atmosphere for very long ... Venusian, yes; Earth, no ...

Where did all the oxygen come from? (you know, the stuff that was merrily lighting up the horizon and that presumably everybody was breathing?)

And did you see any signs of water? [/off topic]
