We use multiple global chemical models to quantify processes contributing to the ozone response to ENSO (El Niño–Southern Oscillation). We find that changes in transport patterns are the dominant factor in the overall ozone–ENSO responses, with the opposing effects of chemical depletion and increased biomass burning on ozone largely offsetting each other. Models consistently project an increase in tropical ozone–ENSO response associated with strengthening anomalous circulation and more abundant water vapor with global warming.
