Learn about projected changes in west coast extreme precipitation due to global warming.

Atmospheric Rivers (ARs) are long and narrow bands of highly-concentrated water vapor that occur in association with winter storms, especially over and near ocean basins. These features are often associated with extreme precipitation and flooding, especially along the mountainous West Coast of North America which receives the majority of its precipitation during the winter months.

Several studies have suggested that climate change could precipitate shifts in the location and intensity of the jet stream, which in turn could impact the location and frequency of ARs. In his Speaker Series presentation Mike Warner will describe his research into these projected shifts and the anticipated impact on associated extreme weather events along the West Coast.
