El Niño is a climate pattern that occurs when sea surface temperatures in the central and eastern Pacific Ocean become abnormally warm. This causes a range of weather changes across the world, including droughts, floods, and extreme temperatures.
Characteristics of El Niño:
a) Increased surface pressure over the Indian Ocean, Australia, and Indonesia
- During El Niño, the trade winds weaken and the warm water that has accumulated in the western Pacific Ocean moves eastward. This causes increased rainfall over Australia and Indonesia, which leads to higher atmospheric pressure in these regions.
b) Rise in warm air near Peru
- El Niño causes warm water to pool near South America, which leads to a rise in warm air in the region.
c) Fall in air pressure over eastern and central Pacific Ocean and Tahiti
- As warm water moves eastward, it causes a fall in air pressure in the eastern and central Pacific Ocean and Tahiti. This leads to changes in atmospheric circulation and weather patterns.
d) Below-average sea surface temperatures across the east-central Equatorial Pacific
- This is not a characteristic of El Niño. In fact, El Niño is defined by above-average sea surface temperatures in the central and eastern Pacific Ocean.
Conclusion:
Therefore, option D is the correct answer as below-average sea surface temperatures across the east-central Equatorial Pacific is not a characteristic of El Niño.

The term El Niño refers to the large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific.
Typical El Niño effects are likely to develop over North America during the upcoming winter season.
La Niño which means cooling of ocean surface water it is opposite of the El Niño southern oscillations.
