Lightning

A new map shows the distribution of lightning strikes across the Earth over the past two decades.

Hot and humid cities can birth more summer thunderstorms than rural areas in the Southeast.

The sun may be partly responsible for lightning strikes on Earth, and scientists think fluctuations in the sun's magnetic field could be used to predict lightning storms weeks in advance.

Expect a 50 percent increase in lightning strikes within the United States by 2100 if temperatures continue to rise due to greenhouse gas emissions.

A high-speed camera run by the University of Florida's Lightning Research Laboratory caught an unusual bolt from the blue in Gainesville.

Before the Hawaii-bound storm Julio strengthened into a hurricane, a NASA satellite spotted a high-energy flash of "dark lightning" coming from the swirling clouds.

Eerie radio signals called whistlers have been detected from volcanic lightning for the first time.

A new study finds in an increase in lightning strikes after large solar winds. The findings suggest that particles from the sun may interact with the atmosphere to make lightning more likely.

The origin of the mysterious reddish lighting above thunderstorms, known as atmospheric sprites, has long puzzled scientists, but they now have some idea how it forms.
