What are atmospheric rivers? – NOAA

Atmospheric rivers are relatively long, narrow regions in the atmosphere – like rivers in the sky – that transport most of the water vapor outside of the tropics. These columns of vapor move with the weather, carrying an amount of water vapor roughly equivalent to the average flow of water at the mouth of the Mississippi River. When the atmospheric rivers make landfall, they often release this water vapor in the form of rain or snow…

‘Rivers in the Sky’: How Atmospheric Rivers Control Nearly All of Earth’s Precipitation – Popular Mechanics

On Jan. 28, 2020, the GOES West satellite traced the path of an atmospheric river flowing across the northern Pacific Ocean (courtesy of NOAA, Public Domain, via Flickr).

“Atmospheric rivers are literally rivers in the sky, the rivers of water vapor that transport massive amounts of water in the atmosphere,” Marty Ralph, a hydrometeorologist, tells Popular Mechanics. Ralph is the founding director of the Center for Western Weather and Water Extremes with the Scripps Institution of Oceanography in San Diego, where he has pioneered research on how atmospheric rivers influence the West Coast…

Atmospheric rivers have been in the news a lot over the past couple of months, from a late October atmospheric river that brought record-breaking rainfall across Northern California to a mid-November storm that led to catastrophic flooding in Washington. A new atmospheric river storm is hitting the Western U.S. now and more are likely on their way. But what exactly is an atmospheric river?

California was lashed by the final in a series of lethal atmospheric rivers Monday night — as officials warned it could take weeks to clean up the sustained heavy rains, snow and floods that’ve hit the state.

The latest: A mandatory evacuation order was issued for a flooded mobile home park in Acampo after 175 residents left voluntarily earlier Monday, per the San Joaquin County Sheriff’s Office…
