Cloth Simulation
Simple Cloth simulation seems to work quite well with Wind effector.
Just play anim and move (G) the Empty arround.
It can be used as a proxy mesh for more detailed model with Surface Deform Modifier.
Spring Bone add-on
just a quick test ... it has gravity parametr, but they can't be influence by effectors like wind.
