Atmospheric Rivers: Weather, Climate, & Societal Interactions

Created by Lauren E. Gentile, Ph.D.

This story map cascade describes how NOAA research is trying to better understand atmospheric rivers, their impacts on communities, and forecast them. The story map also uses a case study to illustrate the complexities of extreme event impacts (floods from ARs, droughts, and frosts) for water resource management in Sonoma County, California.

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2017, the United States experienced a record-tying 16 climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 362 lives, and had significant economic effects on the areas impacted, costing more than $306 billion. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
