Andhra Pradesh and the next El Niño challenge

📌 Summary:

• Context: Even before El Niño formed over the Pacific, Andhra Pradesh in May faced oppressive heat, warm nights and intense heatwaves — daytime temperatures stayed above 44°C for nine consecutive days, peaking at 48.3°C
• Core concern: The record heat heralds a disturbing weather pattern of scanty rainfall and more heatwaves associated with El Niño; on July 12, 2026 the IMD (Amaravati) still issued heatwave alerts for the State
• Causal chain: El Niño (warming of the central-eastern equatorial Pacific) typically weakens the Indian monsoon → reduced rainfall → drought stress, heat stress and pressure on water, agriculture and power
• India's / State vulnerability: Andhra Pradesh has repeatedly borne the brunt of past El Niño events, exposing gaps in heat action and drought preparedness
• Direction of solution (as flagged): the State needs proactive heat-action and drought-preparedness planning ahead of the next El Niño rather than reactive relief

🎯 UPSC Relevance: GS3 (Disaster Management — drought and heatwaves) and GS1 (climatology — El Niño/ENSO and the monsoon). A case study in climate-linked disaster preparedness and early warning.

📝 Prelims Facts:

• El Niño is the warm phase of the El Niño-Southern Oscillation (ENSO), marked by warming of the central and eastern equatorial Pacific
• El Niño years are generally associated with a weaker/deficient Indian southwest monsoon
• Heatwaves are declared by the IMD based on threshold temperatures and departures from normal; India has notified heatwaves for state-level disaster response

🔑 Key Term: El Niño-Southern Oscillation (ENSO) — a coupled ocean-atmosphere phenomenon in the tropical Pacific whose warm (El Niño) phase tends to suppress Indian monsoon rainfall.
