When atmospheric rivers fall to the ground, they often release this water vapor in the form of rain or snow.
Where do most atmospheric rivers occur?
Atmospheric rivers are long, dense regions in the atmosphere that transport moist air from the tropics to high altitudes. The moist air, combined with strong wind speeds, produces heavy rain and snow when it falls, especially in mountainous areas.
