A slowing Atlantic Ocean current is projected to intensify powerful storms in California while reducing snowfall over Greenland, according to a new University of California, Riverside study. … The study in Nature Communications found that as the AMOC [Atlantic Meridional Overturning Circulation] slows, changes in ocean temperatures affect the amount of moisture the atmosphere can hold and strengthen high-altitude winds that steer storms across the Northern Hemisphere. Stronger winds allow storms to transport more moisture toward the West Coast, creating atmospheric rivers. … Although stronger atmospheric rivers increase flood risk and damage to infrastructure, they could also create opportunities to capture more water if communities expand storage capacity and improve forecasting.
