How is an atmospheric river different from a hurricane?
Scientists generally distinguish atmospheric rivers from other storms based on the large amounts of water they carry through the atmosphere – also called vertically integrated water vapor transport, or IVT. “It’s water moving quickly over your head,” Swain said.
What are the effects of an atmospheric river?
When atmospheric rivers flow through the land, they can cause hurricane-like conditions with intense and rapid precipitation, cyclonic force winds, and greatly increased wave heights. In October 2021, an atmospheric river event hit California, severely affecting the San Francisco Bay Area.
