This study investigates the link between Atlantic Niño/Niña and Atlantic hurricane activity. Observations show that Atlantic Niño enhances African easterly wave activity and low-level cyclonic vorticity, increasing the likelihood of powerful hurricanes near the Cape Verde islands. This elevated risk extends to the Caribbean and the U.S. The study contrasts Atlantic Niño/Niña's influence with that of El Niño-Southern Oscillation (ENSO) and the Atlantic Meridional Mode (AMM), demonstrating Atlantic Niño/Niña's unique contribution to hurricane formation, particularly of major hurricanes in the deep tropics.
