I want to suggest a few new uses for winds that I think would be great.
Seed spreading- From your inventory, you can choose to release the wind in the direction you're facing, and many tiles away, depending on the strength of the wind, plants will start to grow in a scattered pattern. Plants on heath should naturally do this.
Scare animals- Same thing with releasing it from your inventory, but it should be able to scare an animal away long enough to get away. Larger animals like bears would need almost hurricane strength wind to scare them.
The already mentioned windmills- Would produce high quality flour, or maybe another type of flour called Finely Ground Flour.
Instruments- A form of outdoor village instrument that ran off of wind that gave certain buffs would be good.
Also, since the skill is "Storm Chasing", we should also be able to collect things like rain water in jars, and lightning with rods. These could be used for various things, and would be interesting to see them with a mystical use, not scientific.
