英文摘要Submesoscale ocean eddies inhibit the growth of La Nina and El Nino events, according to an analysis of long-term high-resolution global climate simulations. The El Nino/Southern Oscillation is characterized by irregular warm (El Nino) and cold (La Nina) events in the tropical Pacific Ocean, which have substantial global environmental and socioeconomic impacts. These events are generally attributed to the instability of basin-scale air-sea interactions in the equatorial Pacific. However, the role of sub-basin-scale processes in the El Nino/Southern Oscillation life cycle remains unknown due to the scarcity of observations and coarse resolution of climate models. Here, using a long-term high-resolution global climate simulation, we find that equatorial ocean eddies with horizontal wavelengths less than several hundred kilometres substantially inhibit the growth of La Nina and El Nino events. These submesoscale eddies are regulated by the intensity of Pacific cold-tongue temperature fronts. The eddies generate an anomalous surface cooling tendency during El Nino by inducing a reduced upward heat flux from the subsurface to the surface in the central-eastern equatorial Pacific; the opposite occurs during La Nina. This dampening effect is missing in the majority of state-of-the-art climate models. Our findings identify a pathway to resolve the long-standing overestimation of El Nino and La Nina amplitudes in climate simulations.
