- C.Both 1 and 2
- D.Neither 1 nor 2
▶ Answer & Explanation
Correct answer: B. 2 only
El Niño Modoki, also known as a central Pacific El Niño, is characterized by warmer sea surface temperatures in the central Pacific, unlike the traditional El Niño which typically forms in the eastern Pacific. The impacts of El Niño Modoki on Atlantic hurricanes are generally considered to be less pronounced or even opposite to those of a canonical El Niño, which tends to suppress hurricane activity. El Niño Modoki, conversely, is associated with an increase in Atlantic hurricane activity.
