Arctic sea ice predictability on daily-to-weekly timescales: sensitivity to initial positional errors under different rheology formulations

Abstract. We investigate short-term (daily-to-weekly) winter Arctic sea-ice predictability using a coupled ice–ocean model, and focusing on how sensitive forecasts are to initial uncertainty in the location of sea ice features (e.g., leads, ridges, etc.). In this context, two rheologies are compared: elastic–viscous–pl...
