Lightning Reloaded!

Spiral clouds of steel blue and ink black, miles-long bolts of lightning, which for a moment appear to cast a spider's web across the sky. Lightning is beautiful, frightening and much more than heavy weather: recent research data indicate that heavy storms and lightning in Africa are generating the notorious Atlantic hurricanes which hit the Caribbean and the US coast every summer. The bolts are even connected to climate change and obviously influence the earth's magnetic field. Where do these lightning strikes come from? How are a billion volts generated and randomly unloaded and where do they go?
