El Nino is dominating the climate conversations across the world. From increased temperature to storms and heavy rainfall, the natural phenomenon has caused bizarre weather anomalies. But what happens when El Nino begins to weaken? In some cases, the Pacific Ocean undergoes a remarkable reversal, shifting from unusually warm to unusually cool conditions and triggering La Nina. The transition is not automatic, but when it happens, it can reshape weather patterns across continents.
The World Meteorological Organisation (WMO) has warned that El Nino’s peak is yet to come and its effects will continue till February 2027.
El Nino and La Nina alternate as part of the ENSO cycle, but not according to a fixed or predictable schedule.
the climate system can occasionally experience the same phase consecutively (such as back-to-back La Nina years) While they often alternate. These are the opposite phases of a natural climate pattern that occurs every 3-7 years.
Together, they are called ENSO, short for El Nini-Southern Oscillation, according to US agency National Oceanic and Atmospheric Administration (NOAA). They do as part of the ENSO cycle, but not according to a strict or predictable schedule.
their impact is felt across the world, resulting in a wide range of changes to global weather While both the weather phenomena originate in the Pacific Ocean. A change in the temperature of the Pacific Ocean, for instance, can influence rainfall in India, droughts in Africa and storms across other parts of the world.
