Probably something to do with preventing static electricity build up. 
I've tried it with the combine when harvesting. The theory being that
the straw passing through the moving parts of the combine builds up 
static electricity and it causes dust to stick to the machine and
windows. I can't say for sure if it helps all that much.
Not sure if it would be such a good thing during a lightning storm.
