I don’t believe there is a high enough density of molecules in the “air” on the moon to produce the same thing we call wind on earth. Sure, they’re going to move around a bit, but they’re unlikely to collide with each other often enough to create a detectable trend of common movement, aka wind.

Great article, I suppose this depends on the definition of wind. But vertical movement of molecules due to a decrease in density from temperature changes sounds like wind with more steps to me.
