Incorrect Statement Explanation:

1. While La Niña conditions enhance the rainfall associated with the Northeast monsoon, it has a negative impact on rainfall associated with the Southwest monsoon:
- This statement is incorrect. La Niña conditions typically bring below-average rainfall to the Indian subcontinent during the Northeast monsoon (October to December) and enhance the rainfall during the Southwest monsoon (June to September).
- During La Niña, the sea surface temperatures in the Pacific Ocean are cooler than normal, leading to increased rainfall over the Indian subcontinent during the Southwest monsoon season.
2. During El Niño, there is abnormal surface warming observed along the eastern and central regions of the Pacific Ocean:
- This statement is correct. El Niño is characterized by above-average sea surface temperatures in the central and eastern Pacific Ocean, which can lead to changes in weather patterns around the world.
- The abnormal surface warming during El Niño can result in drought conditions in some regions and increased rainfall in others, depending on the location and intensity of the phenomenon.
Therefore, the correct answer is option 'A) 1 only.

  • While El Niño the expression heard more commonly in India, is the abnormal surface warming observed along the eastern and central regions of the Pacific Ocean (region between Peru and Papua New Guinea), La Niña (Spanish for ‘little girl’) is an abnormal cooling of these surface waters.
  • Together, the El Niño and La Niña phenomena are termed as El Niño Southern Oscillation (ENSO). These are large-scale ocean phenomena which inflence the global weather — winds, temperature and rainfall. They have the ability to trigger extreme weather events like droughts, floods, hot and cold conditions, globally.
  • While La Niña conditions enhance the rainfall associated with the Southwest monsoon, it has a negative impact on rainfall associated with the Northeast monsoon.
