Steffen Tietsche

Senior Scientist
Research, Earth System Predictability, Extended Range

Summary:

Steffen is interested in ocean and sea-ice variability and predictability, and how these contribute to predictive skill in an Earth System Model.

Professional interests:
  • Subseasonal-to-decadal predictions
  • Sea ice modelling, observation and data assimilation
  • Ocean–sea-ice–atmosphere interactions
  • Ocean reanalysis
  • Forecasting in a changing climate
  • Polar–lower latitude linkages in weather and seasonal prediction
