  • The dark colour of clouds in thunderstorms is caused by water accumulation.

  • A lightning stroke can heat the air through which it travels to an incredible 30,000 degrees Celsius, which is five times hotter than the surface of the sun.

  • The average flash of lightning could light a 100-watt light bulb for more than three months.

  • To estimate the number of miles between you and a thunderstorm, count the number of seconds between the flash of lightning and the next clap of thunder, and then divide this number by five.

  • The average thunderstorm releases the energy equivalent to a 20 kiloton nuclear weapon.
