East meets west: eastern North Pacific controls on precipitation variability in western North America

Session ID#: 27357

Session Description:
The Pacific Ocean is the most important factor controlling weather and climate patterns across western North America. However, the future of the Pacific and its effects on land under predicted climate changes are still a major source of uncertainty that could affect both marine and terrestrial systems. Ocean-atmospheric patterns such as the ENSO and PDO, as well as less-well understood phenomena like atmospheric rivers affect the magnitude and timing of precipitation in western North America. The use of geochemical and biological proxies makes it possible to identify the role that variability in marine conditions has on patterns of terrestrial precipitation. This session encourages submissions utilizing an array of climate-based proxies, especially from sites in the eastern North Pacific or western North America. The goal of the session is to enhance our understanding of the complicated relationships between variability in marine conditions and the downstream effect on terrestrial environments.
