🌊🌬️El Niño & La Niña (ENSO Phenomenon)

🌺El Niño

Meaning: Abnormal warming of sea surface temperature in the central & eastern equatorial Pacific Ocean.

🌾Effect on trade winds: Weaken

🪵Impact on India:

Weak/deficient South-West Monsoon

Droughts, heat waves


🌲Global effects:

Heavy rains in South America

Droughts in Australia & Southeast Asia


La Niña❄️⛄

Meaning: Abnormal cooling of sea surface temperature in the central & eastern equatorial Pacific Ocean.

🌻Effect on trade winds: Strengthen

Impact on India:
Stronger monsoon, above-normal rainfall

Flood risk


Global effects:
Wet conditions in Australia & Southeast Asia

Colder winters in parts of North America


🦖Key Differences (Quick Table)

Feature. El Niño La Niña

Sea temp. Warmer Cooler
Trade wind Weak Strong
monsoon. Weak Strong
ENSO. Warm Cold phase
