Periods of Greater Atlantic Hurricane Activity Linked to Weaker U.S. Landfalls


During periods of greater Atlantic hurricane activity, a protective barrier of vertical wind shear and cooler ocean temperatures forms along the U.S. East Coast, weakening storms as they approach land, according to a new study by NCEI scientist, Jim Kossin. In his paper, “Hurricane Intensification along United States Coast Suppressed during Active Hurricane Periods (link is external),” published in Nature, Kossin identifies this “buffer zone” and describes its relationship with both active and inactive periods of Atlantic hurricane activity.
