Spatiotemporal characteristics and potential drivers of surface air temperature variability in east Antarctica (opens in new tab)

Temperature anomalies in East Antarctica can significantly affect ice sheet stability. However, few studies have focused specifically on this region, leaving a lack of systematic analysis of its temperature variations and driving factors. Utilizing in-situ observations and ERA5 reanalysis from 1979 to 2024, this study systematically investigates the interannual trends, periodicities, and potential drivers of surface air temperature (Ts) in East Antarctica using multiple statistical methods.
