Oh, the abilities?
Air currents/movements.
Basically pushing with air. Whether for herself to suddenly change her directional movement, or for a target to push them away/pull closer.
Although useless against bullets, those go at a high enough speed to 'punch' through the current. Thrown weapons can be easily diverted, while bolts/arrows can only have their trajectory altered by a few degrees.
Also, if used creatively, creating a downwind from your opponent towards you can make eavesdropping slightly easier, as well as masking your own sound.
She can also use it to slightly increase a projectile's range. No, she can not control the air inside a person's lungs, blood, etc. However, having nearby sand/dust blown into someone's eyes is really, really gonna suck.
I highly doubt she would think of a tornado or hurricane. She's not that reckless/unpredictable.
