Profile
Summary: 

Steffen is interested in ocean and sea-ice variability and predictability, and how these contribute to predictive skill in an Earth System Model on time scales from days to seasons.

Professional interests: 
  • Arctic Predictability
  • Polar–lower latitude linkages in weather and seasonal prediction
  • Ocean–sea-ice–atmosphere interactions
  • Sea ice modelling, observation and data assimilation
  • Natural variability and climate change
Career background:
