5/5🧵Key findings:
1) In Enderby Land, significant increases in snow accumulation❄️ – approx 32 % of regional annual average – occur during all extreme El Niño events considered
2) 2015/16 El Niño-SMB changes across Antarctica extend beyond 5th & 95th probability distributions for SON average

4/5 🧵We examine the range of seasonal SMB responses across different Antarctic catchments during different intensities of ENSO events using high-resolution output from a reanalysis-forced Antarctic regional climate model

3/5 🧵 It is essential that we understand how and why snow accumulation varies to accurately predict Antarctica’s future, and the balance between regions of ocean-driven mass loss 🌊 & regions of increased snow accumulation ❄️from climate variability & extreme events 🌨️🌧️

2/5 🧵 Our new research considers how different intensities of ENSO events over the past 40 years impact the balance between snow accumulation 🌨️and melt🧊, to support better future predictions about how Antarctica will contribute to sea level rise 🌊
