This all looks very impressive. What I do, is hold my right arm up, straight over my head would be 100%, as I move my arm down and to the right or left, I adjust based upon where my arm position would be if I was a clock. Once my direction is adjusted accordingly, I divide the wind strength in half and then hit the ball. It seems to work pretty well.
If calculating this, it would look something like this:
u = my arm * cos(θ) v = ws * sin(θ) where θ is the wind direction using "arm" direction, and ws is the wind speed (ie, the magnitude of the wind vector).
Hope this helps.
