Q: 4 (IAS/2010)
A new type of El Nino called El Nino Modoki appeared in the news. In this context, consider the following statements:
1. Normal El Nino forms in the Central Pacific ocean whereas El-Nino Modoki forms in Eastern Pacific ocean.
2. Normal EI Nino results in diminished hurricanes in the Atlantic ocean but El Nino Modoki results in a greater number of hurricanes with greater frequency.
Which of the statements given above is/are correct ?

The correct answer is option 2, which states that the normal El Nino results in diminished hurricanes in the Atlantic Ocean, but El Nino Modoki results in a greater number of hurricanes with greater frequency.

Breaking down both the options, option 1 is incorrect because it states that the normal El Nino forms in the Central Pacific Ocean, while the El Nino Modoki forms in the Eastern Pacific Ocean. In reality, it`s the opposite. The normal El Nino forms in the Eastern Pacific Ocean and El Nino Modoki forms in the Central Pacific Ocean.

Option 2 is correct as during a normal El Nino event, the atmospheric conditions usually result in fewer hurricanes forming in the Atlantic Ocean due to increased wind shear. However, El Nino Modoki has been linked to increased hurricane activity in the Atlantic Ocean due to different atmospheric conditions it creates.

So, option 2 correctly depicts the discussed phenomenon.
