# Pacific Ocean Prepares for Impact: NASA Detects Precursors to a Powerful El Niño

The Pacific Ocean, usually a calm giant, is beginning to show worrying signs. NASA satellites have recorded a massive movement of warm water masses, which could become the prologue to the formation of the El Niño climate phenomenon as early as 2026. This event has the potential to overturn the weather map of the entire planet.

### The Hidden Mechanism of Climate Anomaly

Scientists are focusing on so-called Kelvin waves — giant currents of warm water that serve as a reliable harbinger of El Niño. These waves move eastward through the equatorial zone of the ocean and have already reached the coast of South America. Their movement is being monitored by the Sentinel-6 Michael Freilich satellite, created as part of a collaboration between NASA and the European Space Agency.

The monitoring system's principle of operation is simple and effective: the satellite measures the ocean surface level every 10 days. Since warm water has the property of expanding, even a slight heating causes a rise in sea level. This is how scientists discovered the anomaly: in mid-May, the ocean level off the coast of Peru exceeded the long-term norm by more than 15 centimeters.

### How Winds Trigger Global Changes

The formation of Kelvin waves depends directly on the behavior of winds over the western part of the equatorial Pacific Ocean. Under normal conditions, easterly winds drive warm water westward. However, when these winds weaken or change direction to the west, the warm mass begins to accumulate and gradually move toward the shores of South America.

The accumulation of warm water off the coasts of Colombia, Ecuador, and Peru is a classic scenario for the development of El Niño. Josh Willis, a sea level researcher at NASA's Jet Propulsion Laboratory, notes that the current process is still lagging behind the super-powerful phenomena of 1997 and 2015, but the situation is changing rapidly.

### Global Consequences for Weather

El Niño is not just a local warming of the ocean. Changes in surface temperature in the central and eastern parts of the Pacific Ocean restructure atmospheric flows and storm trajectories worldwide. The result is sharp contrasts: in some regions, torrential rains and floods rage, while in others, heat and droughts reign.

History knows examples of both moderate and catastrophic manifestations of this phenomenon. The powerful El Niño of 2015–2016 caused widespread droughts in Africa and devastating floods in California. Séverine Fournier, deputy scientific lead of the Sentinel-6 project, emphasizes: "Each cycle is unique, but they almost always make the year hot and cause major changes in precipitation."

### When to Expect the Peak of the Anomaly

The peak activity of El Niño usually falls between November and January, so the final scale of its impact will only become clear at the end of the year. For now, meteorologists predict that this summer will be cooler and not as hot as in previous years. The weather will resemble spring more, which could be a pleasant surprise for many regions.

Nevertheless, Western Europe is currently suffering from record heat. Temperatures recorded at the end of May are more characteristic of July. This clearly demonstrates how complex and unpredictable the modern climate system can be.
