That relative motion can be generated by weather pattern (which are indeed driven by pressure differences) or by the motion of a conveyance that I ride through a placid indoor space. Nor is wave-like behavior necessary: a steady-state flow is still a breeze. There is a lot here that could be part of a nice discussion of wind in general, but it's poking around "where does a natural wind come from" instead of the thermal transfer from moving air question the OP asked. | |
| May 31, 2017 at 17:02 | comment | added | Eph | @dmckee A breeze is a relatively small deviation of the mean velocity from zero with a corresponding pressure gradient that allows that velocity to propagate (in a wave like fashion). Saying a breeze is not a pressure phenomena is like saying light is only a small deviation in electric field, it's not a magnetic phenomena . | |

Pressure differences are highly related to the wind (though I'm not a meteorologist and don't know enough about it to say if it's a thermal action creating pressure difference that drives the wind, or thermal variations drive movement which creates pressure differentials, etc.). Either way I agree it isn't accurate as is. | |
