● The Hindu: Indian Ocean Dipole (IOD) is an event which the western Indian Ocean becomes alternately warmer and then colder than the eastern part of the Indian ocean. So first statement is wrong. ● A positive IOD leads to greater monsoon rainfall and more active (above normal rainfall) monsoon days while negative IOD leads to less rainfall and more monsoon break days (no rainfall). So yes, IOD can influence El Nino's impact on Monsoon. So second statement is right.
