El Niño & Monsoon
• El Niño = abnormal warming of central & eastern equatorial Pacific Ocean; generally weakens India’s south-west monsoon.

• La Niña = abnormal cooling of eastern Pacific; generally supports better monsoon rainfall in India.

• El Niño affects India by disturbing Walker Circulation - the east-west wind circulation across the tropical Pacific.

• During El Niño, moisture transport towards the Indian subcontinent weakens —> below-normal rainfall risk.

• India’s major El Niño-linked deficient monsoon years: 1972, 1982, 1987, 2002, 2009, 2015.

• ENSO phases: El Niño, La Niña, ENSO-neutral.

• IOD = Indian Ocean Dipole: temp. contrast between western and eastern Indian Ocean.

• Positive IOD:
• Western Indian Ocean = warmer than normal
• Eastern Indian Ocean = cooler than normal
• Can partly neutralise El Niño’s negative impact on monsoon.

Concept Link:
• El Niño + Negative IOD —> Strong monsoon suppression
• El Niño + Positive IOD —> Monsoon impact may reduce/partly neutralise.
