The polar regions are among the most sensitive areas to global warming and hold a key to understanding the pace and trajectory of climate change. In this context, we investigate the responses of Antarctic snowfall, sea ice extent, and ice sheet dynamics to major modes of climate variability—including the El Niño–Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Southern Annular Mode (SAM)—and explore the underlying dynamical mechanisms governing these interactions. Building on this understanding, our work aims to improve the performance and reliability of cryospheric models. This study seeks to elucidate how both remote and local climate variabilities influence the stability of the Antarctic cryosphere, how these mechanisms affect predictability, and how such scientific insights are being integrated into the advancement of climate modeling frameworks.
