heres a quick idea i just came up with for what you want(untested, just a theory):
1) for hair blowing in the wind, you could set up a bone(or set of bones, depending on the complexity of the hair); set up a dumby object on the head that has the 'wind force' applied to it; apply another force like elastic so that the dumby object cant go too far. then, rotate/position the bones/limbs of the hair to match the dumby object. then, they hair will flow in the direction of the wind.
2)for leaves swirling in the wind, you might not even need physics(except for the leaves colliding into other objects). to have them swirl, you could use a mathematical function for a spiral; have the leaves' x and z positions follow the spiral(with randomness added in so that it doesnt look fake). then, set the y as a function being so that the leaves move closer to the ground as x and z approach 0 on the spiral. also, to add even more realism, you could move all of leaves in a group in one direction so that the leaves spiral while heading in a certain direction
i could go into more complexity with this if i had dark physics, but thats the gist you could work with. i hope you could understand what i ment
