Short summary
This study integrates high-resolution ERA5 reanalysis with precise ice core isotope measurements to assess summer water isotope variability at Hercules Névé in East Antarctica. By focusing on the austral summer (DJF), it minimizes post-depositional effects and elucidates the roles of temperature, precipitation, and wind patterns, including effects from the Amundsen Sea Low and Zonal Wave-3. The 40-year record refines paleoclimate reconstructions and Antarctic climate understanding.
