Short summary
This study evaluates the impact of enhanced seasonality characteristic of the Marine Isotope Stage 31 (MIS31) on the El Niño–Southern Oscillation (ENSO). Based upon coupled climate simulations driven by present-day (CTR) and MIS31 boundary conditions, we demonstrate that MIS31 does show a strong power spectrum at interannual timescales but the absence of decadal periodicity. The implementation of the MIS31 conditions results in a distinct global monsoon system and its link to the ENSO.
