The Indian Ocean Dipole/Zonal mode (IOD) is an interannual phenomenon over the tropical Indian Ocean, causing a pronounced impact worldwide. Here, the authors investigate the mechanism of the change in IOD characteristics in a CO2 removal simulation for an earth system model (ESM). As the CO2 concentration increases, the intensity of IOD tends to increase, but at high CO2 concentrations, further increases decrease the IOD intensity.
