La Nina is suspected to have caused recent floods in Australia. How is La Nina different from El Nino?
- La Nina is characterized by unusually cold ocean
- El Nino has adverse effects on the south-west monsoon
of India, but La Niña has no effect on monsoon climate. Which of the statements given above is/are correct?
Explanation
The correct option is "Neither 1 nor 2" because both statements contain inaccuracies regarding the climatic phenomena. Firstly, La Niña is characterized by unusually cold ocean temperatures in the equatorial Pacific Ocean, not the Indian Ocean, while El Niño features unusually warm temperatures in the same region. Secondly, both El Niño and La Niña can significantly impact monsoon patterns in India; El Niño typically leads to weakened monsoons, while La Niña can enhance them. Understanding these distinctions is crucial for comprehending the complex interactions of global climate systems, which is a key focus for UPSC examinations.
