Where does lightning strike? New maps pinpoint 36.8 million yearly ground strike points in unprecedented detail

A new study shows how often lightning strikes and how it behaves, often hitting the ground with multiple strikes from the same flash.

Monsoons make deserts bloom in the US Southwest, but climate change is making these summer rainfalls more extreme and erratic

Monsoons are weather patterns that bring thunderstorms and heavy rains to hot, dry areas when warm, moist ocean air moves inland. They’re challenging to forecast, especially in a changing climate.
