2012 - Science Or Superstition?/AFA/6

If a stream of solar particles can cause radio fade-out, it can also affect satellite communications. But I don't think that it's going to have any large-scale geophysical effect on the Earth. And I suppose you could, if you really want to push it, you could connect with weather, but we have to remember that the bulk of the effects it produces - hurricanes, tornadoes - is entirely encased within the Earth. It's got a lot more to do with rotation and circulation of air than it does with these outside effects. But I would admit that it could have a meteorological effect.
