- El Nino-Southern Oscillation (ENSO) - El Nino creates strong vertical shear that suppresses hurricane activity whereas it increases the temperature of the Eastern Pacific waters, reducing wind shear and therefore increasing Eastern Pacific activity. La Nina reduces Atlantic wind shear therefore increasing Atlantic hurricane formation but increases Eastern Pacific shear which decreases Eastern Pacific storms.
How does El Niño affect hurricane season?

El Niño suppresses Atlantic hurricanes and boosts eastern Pacific activity, and La Niña does the reverse.
