While atmospheric rivers vary in size and shape, those containing large amounts of water vapor, strong winds, and that stall over watersheds vulnerable to flooding, can
create extreme rainfall and floods.
In 2014, Climate Central helped
create the World Weather Attribution (WWA) initiative, a groundbreaking international effort to analyze and communicate the possible influence of climate change on
extreme weather events such as storms,
extreme rainfall, heat waves, cold spells, and droughts.
