Declining Arctic sea ice thickness and extent over the past several decades has resulted in extensive regions of thin ice vulnerable to melting. We use the ERA-5 reanalysis along with a fully coupled atmosphere-ocean-ice model (Navy ESPC) to explore the role of Arctic cyclones in summertime sea-ice change. Cyclone influence on short-term changes in sea ice vary markedly between early and late summer. Cyclones account for over 70% of the annual poleward moisture transport into the Arctic. We utilize the coupled Navy ESPC to examine the key processes that led to sea ice loss during an intense cyclone.
