When the RH is lower, though, it has the effect of replacing saturated air (next to the liquid water source) with air that isn't saturated. This does increase the rate of evaporation, but the wind isn't causing the evaporation. It's just providing a better environment for evaporation to occur.
The OP seems to be saying that the wind can blow the molecules off the surface. That's accurate, more or less, isn't it? Blowing spray into the air, increasing surface area, etc, can cause more evaporation, no?
