If you were to look at it from a real life perspective, then yes...they would be different. Air is the atmosphere from which we breathe, wind is movement of particles of air from within the atmosphere, mostly through differences in temperature (and on a similar token, pressure), as well as the Coriolis effect for its direction. Real life doesn't hold as much weight here, however.

From an anime / magic standpoint, no, they wouldn't be different, as both could be used to achieve the same thing since more or less they are the same, just one comes from within the other.

If I recall [EDIT: They do, I just checked], the Dust page classifies them as "Wind or Air." Most of these dual kinds are just wording issues, not separate kinds, however. (Lightning/Electric, Fire/Burn, to name a couple others.)

So no, I wouldn't classify them as different, even if they fundamentally IRL are.
