Atmospheric river storms create $1 billion-a-year flood damage

Researchers found that flooding has caused nearly $51 billion in damages to western states in the last 40 years. More than 84 percent of these damages were caused by atmospheric rivers (ARs), long narrow corridors of water vapor in the atmosphere capable of carrying more than twice the volume of the Amazon river through the sky. https://www.sciencedaily.com/releases/2019/12/191204152842.htm
