Building a Hurricane Season in the Atlantic Ocean

NASA researchers use computer models to study hurricanes, focusing on three ocean patterns: El Niño Southern Oscillation, North Atlantic Oscillation, and Atlantic Meridional Mode. These factors influence hurricane formation by affecting sea surface temperatures, pressure, and wind speed. El Niño and La Niña impact Pacific temperatures, altering Atlantic wind conditions. The North Atlantic Oscillation involves pressure differences that affect hurricane likelihood. The Atlantic Meridional Mode describes temperature variations north of the equator. Case studies from 2005 and 2013 illustrate these patterns' effects on hurricane seasons.

Describe the impact of the Atlantic meridional mode on hurricane activity.
