Atmospheric rivers—relatively long, narrow regions in the atmosphere—transport most of the water vapor outside of the tropics. When a large atmospheric river makes landfall, extreme precipitation—sometimes double the amount of rain that fell in the preceding 5 months—and flooding can result. The frequency and intensity of atmospheric rivers and droughts are just two realms explored in a new report that focuses on the effects of climate change across the United States.
