These are whats commonly called light pillars. They are said to occur due to light reflecting from ice crystals. But Since light is also part of the electromagnetic spectrum, maybe something else is happening here?
"North and South Pole magnets are not only holding together the earth and moon, but they are turning the earth around on its axis. Those magnets which are coming form the sun are hitting their own kind of magnets which are circulating around the earth and they hit more on the East side than on the West side, and that is what makes the earth turn around. North and South Pole magnets make the lightning, in earth's North hemisphere the South Pole magnets are going up and the North Pole magnets are coming down in the same flash. The North lights are caused by the North and South Pole magnets passing in concentrated streams, but the streams are not as much concentrated as they are in the lightning. The radio waves are made by the North and South Pole magnets. Now about the magnet size. You know sunlight can go through glass, paper and leaves, but it cannot go through wood, rock and iron, but the magnets can go through everything. This shows that each magnet is smaller than each particle of light." EDL
