Short summary
The interplay between the El Niño–Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) is well-researched in the tropical Indian Ocean, but their effects on the Southern Hemisphere's extratropical regions during spring are less studied. We show that the positive phase of the IOD can strengthen the El Niño circulation anomalies, heightening their continental impacts. On the other hand, negative IOD combined with La Niña shows less consistent changes among the different methodologies.
