The problem is, we don't know. 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 theiry), 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 of the blitz...
