In a small lab at Penn State University, lightning may be happening on a scale smaller than a deck of cards. Victor Pasko, a professor of electrical engineering, and his team have shown that under ...

Thunderstorm clouds have a lot of air moving around inside them, including updrafts and downdrafts, which can be strong. Updrafts transport tiny drops of rain and ice crystals to the top of the ...

Inside a thunderstorm, warm air is forced upward in a strong updraft. As the air rises, ice and water particles collide inside the cloud, creating electrical charges. Those collisions build up ...

Researchers at Stony Brook University may have captured lightning in a bottle — or at least explained one of the theories of how it is created. Working with researchers in Spain and China, Stony Brook ...
