WMO Warns of Unprecedented Strength in Ongoing El Nino Event
Source:The Hindu ↗
ఇది ఎందుకు ముఖ్యం
Understanding climate patterns like El Nino is critical for India's monsoon forecasting, disaster management, agricultural planning, and ensuring food security.
సారాంశం
The World Meteorological Organization (WMO) has issued warnings regarding an ongoing El Nino event, indicating that its strength could reach unprecedented levels, triggering severe global climate anomalies, extreme weather events, and impacts on agriculture and water security.
ముఖ్య అంశాలు
- The World Meteorological Organization (WMO) warned that the El Nino event could be unprecedented in strength, impacting global weather patterns.
- El Nino involves the warming of sea surface temperatures in the central and eastern tropical Pacific Ocean.
- Such intense climatic anomalies severely influence monsoons, agricultural output, water security, and trigger extreme weather phenomena globally.

What are the primary phases and oceanic-atmospheric indicators of the ENSO cycle?
- El Niño Phase: Abnormal warming of central and eastern tropical Pacific Ocean sea surface temperatures, weakening Walker circulation and disrupting global monsoons.
- La Niña Phase: Abnormal cooling of the eastern Pacific, strengthening trade winds, enhanced upwelling off South America, and usually robust Indian monsoons.
- Neutral Phase: ENSO neutral phase with near-normal sea surface temperatures and standard atmospheric circulation patterns across the equatorial Pacific basin.

El Niño and Indian Food Security
El Niño-induced drought and agricultural stress directly intersect with food security mandates, public distribution systems, and fiscal burdens from crop insurance (PMFBY).
ENSO cycle mechanics combined with Indian monsoon spatial variation will likely feature in a multi-statement Prelims question.
