Feedback loop between Arctic sea-ice decline and eddy dynamics: Lessons from an ultra-high resolution climate model Open
The Arctic sea ice is vanishing at an alarming pace, far outstripping the predictions of many current climate models (Shu et al., 2020). This growing discrepancy suggests that vital oceanic processes—especially (sub)mesoscale eddies respon…
