Question

La Nina is suspected to have caused recent floods in Australia. How is La Nina different from El Nino?
1. La Nina is characterised by unusually cold ocean temperature in equatorial Indian Ocean whereas El Nino is characterised by unusually warm ocean temperature in the equatorial Pacific Ocean.
2. El Nino has adverse effect on south-west monsoon of India, but La Nina has no effect on monsoon climate.
Which of the statements given above is/are correct?

Accepted Answer

The correct answer is D because both statements provided are incorrect.

Statement 1 is incorrect because both La Nina and El Nino are phenomena primarily associated with the equatorial Pacific Ocean, not the Indian Ocean. La Nina involves unusually cold ocean temperatures in the central and eastern equatorial Pacific, while El Nino involves unusually warm temperatures in that same region.

Statement 2 is incorrect because La Nina has a very significant effect on the Indian monsoon. While El Nino is generally associated with poor rainfall or droughts in India, La Nina is typically associated with better than average rainfall and a stronger south west monsoon. Therefore, saying it has no effect is factually wrong.
