Popis: In the background of global warming, the necessity for finding a new predictor of Indian summer monsoon rainfall (ISMR) is realised recently as the relationship between the ISMR and the predictive physical parameters keeps changing both in space and time. We developed a linkage between the satellite-derived sea ice over the Southern Ocean and ISMR through the interaction of physical processes occurring between the cryosphere, hydrosphere, and atmospheric environment. The statistical and possible physical linkage were explored using consistent and reliable 38-year time series observations. Lead-lag cross correlation indicated a significant relationship between Southern Ocean sea ice (SOSI) extent and ISMR over the Bellingshausen–Amundsen Sea (BAS). The most significant relationship was obtained in austral autumn (r = −0.5, p
