Consider the following statements about El Nino Modoki
1. Normal El Nino is associated with unusual warming of the eastern tropical Pacific Ocean while El Nino Modoki is associated with unusual warming of western tropical Pacific Ocean.
2. Normal El Nino results in diminished rains in the Indian subcontinent while El Nino Modoki leads to heavy rains in Indian subcontinent.
Which of the statements given above is/are correct?
Both 1 and 2
Incorrect Answer Neither 1 nor 2
Correct AnswerExplanation:
Conventional El Niño is characterized by strong anomalous warming in the eastern equatorial Pacific (see figure below). Whereas, El Niño Modoki is associated with strong anomalous warming in the central tropical Pacific and cooling in the eastern and western tropical Pacific.
During El Niño years probability is high that there will be less rainfall in India but this need not be necessary. During El nino Modoki also there is probability of diminished rainfall in the Indian subcontinent.
Also, due to El Nino Modoki Arabian sea has more number of cyclone during pre-monsoon and post-monsoon seasons as opposed to general phenomena whereas Bay of Bengal has higher number of cyclone during pre-monsoon and post-monsoon.
