How could the El Niño/La Niña climate cycle affect South Asia?
El Niño cycle may increase drought and flood risks across South Asia The strengthening El Niño event, which is characterized by above-average sea surface temperatures in the tropical Pacific, is expected to shift global rainfall patterns. This shift increases the risk of both drought and floods in various regions, including South Asia. For instance, reports note that El Niño impacts Sri Lanka, increasing its drought risk. These climate shifts can lead to severe consequences for South Asia, such as crop failures, food shortages, and disruptions to water supplies.

How it reaches South Asia
-
Scientific bodies are monitoring the transition from La Niña to El Niño. Research published in Communications Earth & Environment found that even if carbon dioxide emissions ceased, changes to ocean temperatures, winds, and rainfall patterns in the tropical Pacific could endure for hundreds of years. Meanwhile, authorities are preparing for severe weather associated with the El Niño season, which is noted to be more than 36% stronger than before the industrial era.
The full event32independent outlets -
The El Niño/La Niña phases are part of the El Niño–Southern Oscillation (ENSO) cycle, which involves coherent year-to-year variations in sea surface temperatures and atmospheric circulation across the equatorial Pacific Ocean. The National Oceanic and Atmospheric Administration tracks these changes to predict global weather patterns.

The warming of the tropical Pacific alters atmospheric circulation, causing changes in tropical rainfall patterns around the globe. This can result in increased risks of drought and floods in different regions, such as Southeast Asia and South Asia, potentially leading to crop failures and food shortages.

The facts so far
As reported. Each one links to where it comes from.
- El Niño and La Niña represent opposite extremes in the El Niño/Southern Oscillation (ENSO) cycle.thenassauguardian.com
- El Niño is likely to bring above-average temperatures to much of the globe and shift rainfall patterns, increasing the risk of drought and floods in different regions.miragenews.com
- Consequences of El Niño can include crop failures, food shortages, famine, disruptions to water supplies, and increased risks of wildfires.thenassauguardian.com
Why it matters
South Asia relies heavily on predictable weather patterns, particularly monsoon cycles, for its agriculture and water security. The potential for El Niño to shift rainfall patterns introduces significant risks of both prolonged drought and severe flooding. These climate extremes directly threaten food supplies and can lead to economic disruption and population displacement.
Globally, the ENSO cycle is a major driver of interannual variability in tropical climate. While the reports note that El Niño is a natural climate phenomenon, the increasing strength of these events due to climate change means that the potential for severe, widespread impacts is growing, requiring preparation for major resource shortages.

Beyond this explainer
Questions worth asking
Ideas the web ties closely to this story that the explainer doesn't mention. These are prompts for your own research: Brind hasn't answered them.
-
About Decadal Cycles
How might longer-term decadal climate cycles interact with the short-term shifts caused by El Niño to influence South Asia's monsoon reliability?
-
About Different Altitudes
Since climate shifts affect rainfall, how might the impact of El Niño differ between low-lying coastal areas and regions at different altitudes in South Asia?
