Imagine a swing. Someone pushes it quickly and often—those are wind gusts over the ocean. The swing itself rocks slowly—that's El Niño, the warm patch in the ocean that changes weather worldwide. Previously, scientists couldn't unite these two motions in one model: the rapid pushes disrupted the slow rhythm.
The new model works like a bridge between fast wind gusts and slow currents. It showed that the strength of the gusts depends on how warm the ocean already is. Warm water intensifies the wind, and the wind further warms the water. That creates a feedback loop.
The model reproduced what is observed in the ocean: sometimes the warm patch appears near the coast, sometimes in the center, and sometimes it persists for two consecutive years. The frequencies matched real observations over 71 years. Even rare, very strong El Niño events were correctly captured by the model.
Now scientists can run the model on an ordinary laptop and generate thousands of years of virtual climate. This will help better predict the droughts and floods that El Niño brings.
The model reproduces delayed super El Niños, similar to the 2014-2015 event, when strong easterly wind bursts temporarily suppressed the growth of warming, and then westerly bursts pushed it to extreme levels.
In Kim Stanley Robinson's novel 'The Ministry for the Future', extreme climate events, including heat waves and floods, are linked to changes in tropical circulation. Although there is no direct description of MJO-ENSO, the idea that small atmospheric disturbances can trigger global consequences echoes the mechanism of El Niño initiation by wind bursts.
