"Arctic Sea Ice Predictability in a Changing Cryosphere"

Abstract:
Forty years of satellite observations have documented a striking decline in Arctic sea ice area. These changes have spurred research into the predictability and prediction of Arctic sea ice on seasonal-to-interannual timescales
In this talk, I will address two related questions: (1) What is the inherent predictability of Arctic sea ice and what physical mechanisms underlie this predictability? and (2) How can this knowledge improve operational sea ice predictions? I will present findings on the relative roles of the ocean, sea ice, and atmosphere in controlling Arctic sea ice predictability. I will also present evidence for a spring predictability barrier, which may limit our ability to predict the summer sea ice minimum.

Light refreshments will be served.
