The problem is, we don't know. Well, the rain and thunder can't be prevented, like a butterfly can't change the course of a storm. But it could prevent a lightning bolt from blitzing the ringer, while it could change the paths of the lighting strokes so he'll be blitzed down and stop his ringing, which has happened frequently.
So it could influence the storm and paths of lightning (chaos theory), but the energy thrown down from the clouds and the rain falling will not be influenced. Maybe if the ringer gives off a strong directed yell it will bump off the blitz...
So, while the ringing might influence the chaotic processed that are super sensitive to initial conditions, like lighting flashes are, it will have no effect on the clouds that run, the wind that blows and the rain that falls.
