  text: The Indian summer monsoon rainfall (ISMR) has been declining since the 1950s.
    However, since 2002 it is reported to have revived. For these observed changes
    in the ISMR, several explanations have been reported. Among these explanations,
    however, the role of the eastern equatorial Indian Ocean (EEIO) is missing despite
    being one of the warmest regions in the Indian Ocean, and monotonously warming.
    A recent study reported that EEIO warming impacts the rainfall over northern India.
    Here we report that warming in the EEIO weakens the low-level Indian summer monsoon
    circulation and reduces ISMR. A warm EEIO drives easterly winds in the Indo–Pacific
    sector as a Gill response. The warm EEIO also enhances nocturnal convection offshore
    the western coast of Sumatra. The latent heating associated with the increased
    convection augments the Gill response and the resultant circulation opposes the
    monsoon low-level circulation and weakens the seasonal rainfall.
