Lightning is almost inevitably associated with towering cumulonimbus. Plain old thunderstorms. Professor Isaac teaches meteorology and climatology and is director of Ohio University's Scalia Laboratory for Atmospheric Analysis. Probably one of the most spectacular sights on the planet. So, somebody looking at the blue planet from space would see these features of which we've only just barely become aware of.
Lightning is an electrical discharge through the atmosphere of extremely high voltage.
Isaac says a bolt can generate as much heat as the sun. You start with air and water. But we can expect it at any time during the day. Pay attention to the national weather service. Listen, pay attention to the warnings of severe thunderstorms.
