Dr. Marty Ralph, Director, Center for Western Weather and Water Extremes (CW3E) at UCSD’s Scripps Institution of Oceanography joins us to kick off 2022 by discussing his research into atmospheric rivers, the long narrow bands of concentrated water vapor that produce major amounts of rainfall. We discuss how they relate to El Nino, La Nina, and last year’s bomb cyclone, and how his research is helping California reservoir operators prepare for future storms to save water and help California manage its climate-change future.
