The effect of ENSO on Arctic sea ice as a source of predictability
Thesis (Master's)--University of Washington, 2019 ENSO is the primary mode of global climate variability but its links to Arctic sea ice are uncertain, in part due to the short observational record. The Community Earth System Model is used to constrain the effect of ENSO on Arctic sea ice conce...
