If you're unfortunate enough to have experienced a tornado, we imagine you didn't waste much time wondering why there wasn't any lightning along with the tornado; you'd have been too busy either running away or finding somewhere to shelter. It's a fair question though; lightning comes with every other type of storm, so why would a tornado be any different?
The answer of course is that it isn't, as we can see here. The unique atmospheric conditions created by a tornado mean that the lightning just never reaches the ground. Instead, it shoots from cloud to cloud, crackling and fizzing across the sky, often difficult for the human eye to pick out, but obvious to a camera lens. The energy charge from the lightning actually feeds the tornado and helps it to keep spinning. That's the last thing anyone needs!
