The correct answer is 2 only.

Key Points

  • El Nino Modoki:-
    • Modoki was a Japanese term that means The same thing but different.
    • El Nino Modoki was a new type of El Nino which formed in the Central Pacific, not in the Eastern Pacific Hence 1 is not correct.
    • It warmed the central pacific with a greater potential for making landfall along the gulf coast and coast of central America.
  • Normally El Nino results in diminished hurricanes in the Atlantic ocean but El Nino Modoki results in a greater number of hurricanes with greater frequency, Hence statement 2 is correct.

Additional Information

  • El Nino Effect-
    • El Nino is a climate pattern that refers to the unusual warming of surface waters in the eastern tropical pacific ocean.
    • It was first recognized by Peruvian fishermen off the Peru coast.
  • Hurricanes-
    • These are large, swirling storms.
    • They produce winds of 119 km/h or higher.
    • They form over warm ocean waters.
    • It starts out as a tropical disturbance.
    • Two factors are responsible for the formation of Hurricanes-
      • Warm Ocean Waters
      • Winds that don't change much in speed or direction.
